LIFE: ITS NATURE, ORIGIN, DEVELOPMENT, AND THE PSYCHICAL RELATED.TO THE PHYSICAL. BY SALEM WILDER. BOSTON: Press oe Rockwell and Churchill, 39 Arch Street. 188 6. Copyright, 1886, SALEM WILDER. Press of Rockwell and Churchill, Boston. PREFACE. The writer is impressed with the idea that much more might be properly written concerning the Nature of Life and the duties which must accompany living. He does not expect to add much which is new; but the thoughts here recorded have remained after an extended reading of emi- nent authors who have written upon like subjects. Moral questions receive special attention, and are dis- cussed from a common-sense point of view; but a striking coincidence is to be noted in the fact that those nations which have done most to enlighten the world through biological, psychological and physiological investigations have been professedly Christian. The sceptical as well as the believing have a right to know from what stand-point the writer urges his views ; and both may ask why he speculates concerning matters beyond the comprehension of the human intellect. The belief of an author cannot alter the significance of a single fact, nor can the disbelief of any other man affect the position of actual truth; yet our peculiar views upon moral and religious subjects do color our reason- ings, even when dealing with matters not directly moral or religious. Many passages have been wrought into the text which PREFACE. others might have allowed to appear as notes. Certain parts of the work consist of fugitive thoughts written at various times during the past ten years, and in some instances these thoughts are imperfectly interwoven, and there will be found many digressions from the main line of the argument. Certain imperfectly understood teachings of nature have been perverted by a class of eminent men, and some one should restate these teachings from a different point of view. The writer has endeavored not to state as fact what does not rest upon good authority; but in writing what follows he assumes a serious responsibility. In the border lands of theory and speculation the lines of truth are not always clearly defined. To mislead is easy, and to mislead in important lines of thought may do harm; yet men must bear the responsibility of their honest convictions. If the following pages shall incline readers to think and seriously inquire " What is truth ? ” the chief desire and ex- pectation of the author will be realized. s. w. Boston, February, 1886.

CHAPTER I. LIFE, WHAT IS IT? In treating a subject concerning which so little is posi- tively known the writer proposes to present a few significant facts and considerations. Let us inquire concerning some of the general character- istics of that incomprehensible and invisible element or mani- festation which we call life. Life in its essence is a mystery ; but the earth teems with numberless varieties of living creatures, and the phenomena of life are so common that we look upon them as part of the course of nature. We are not inclined to inquire concern- ing life’s origin and extent except in meditative moments, or when impelled to serious thought by the vicinage of death. Then we are often disposed to inquire whence? whither? But when we attempt to push our inquiries into the nature of life we may read over the portals of its temple, "Walk softly here,” for the ground on which we tread is under thickest mystery. Why do we say of one that he is alive, and of another that he is dead? What is life? and also its opposite, death ? 2 WHAT IS LIFE? For present purposes I assume that life is a manifestation of the vital energy or principle which preserves health and strength in living beings. But in one sense this assumption does not bring us a just conception of the proper answer. I however assume that a vital energy or principle exists, though well aware that biolo- gists are in dispute upon this very point. Dr. H. C. Bastian (p. 56, "Beginnings of Life ”) says : " Two fundamentally opposite doctrines have been main- tained again and again as to the nature of life, under one or the other of which all the views ever promulgated on this subject may be ranged. According to the one school, life is to be regarded as the principle or cause of organization; and, according to the other, life is the product or effect of organization.” H. C. Bastian and others regard life as the effect of or- ganization. Hunter, Huxley, and many other eminent physiologists regard life as the cause rather than the consequence of or- ganization. If life is merely the result of organization, then men and animals are simply organized machines brought together by and under the complete control of the mechanical forces of nature. Chemists have labored to produce living matter, but so far have utterly failed in these endeavors. Organic matter has been analyzed, and its chemical constituents, carbon, oxygen, nitrogen, sulphur, etc., are well known. But when chemists combine these elements in the same proportions no breath comes,, no throbbing heart, no blood circulation; in fact, not the slightest trace of what we distinguish by the name of life. WHAT IS LIFE? 3 It should be borne in mind that living protoplasm has not been and cannot be analyzed. A chemist can say that dead protoplasm is compounded of carbon, nitrogen, oxygen, sulphur, etc. ; but, when he attempts to analyze living proto- plasm, death takes place, and it is only dead protoplasm which he analyzes. What escapes in the passage from life to death cannot be recognized by chemistry, and probably it has no chemical quality. By using poisons which would destroy all animal life chemists may produce certain substances like those produced in the animal system at normal temperature ; or, by using a degree of heat utterly destructive to animal life, something similar has been produced. But in animals these are pro- duced with moderate temperature, and without poisons. So radically different are the actions of chemicals in the laboratory and the chemical actions in living beings which produce like results. Yet some have asserted that the pro- duction of urea by chemists is an indication that life in ani- mal organisms is the result of chemical action or chemical combinations. Dr. Lionel Beale, the distinguished physiologist and mi- croscopist, writing on this point, says (" Protoplasm, or Matter of Life,” p. 270), "All the force, all the heat, all the motion, in the non-living universe is incompetent to de- velop a living monad; and this the physicists know. In their view of the construction of living beings they ignore the fact of the existence of an already existing organism ; but this existence is absolute. They ingeniously invest attendant circumstances and external conditions in the garments of causes, and persuade the public that these are all in all. They then ignore, or deny, the inheritance of life, which is all in all, and without which all matter, all force, all possible 4 WHAT IS LIFE? attendant circumstances and external agencies are as nothing.” Huxley admits that carbonic acid, water, and ammonia cannot combine to produce protoplasm, or the matter of life, unless the principle of life presides over the operation. Even Hseckel, the monistic naturalist, admits that life cannot be produced by chemistry. However, there is chemical action in the animal system, and the work of waste and repair of the animal tissues con- stantly goes on. But no chemist has ever been able to pro- duce the simplest animal organism, much less intelligence, the distinguishing trait of all higher forms of animal life. Chemists may analyze and combine as they will, but some- thing is still wanting. The germ of life must be implanted before the living active machine can be set in motion. We confess that from the teachings of science we have no knowledge of life separate from matter; for all manifesta- tions of life we have ever seen, whether animal or vegetable, have been connected with matter. But that is by no means proof that life cannot exist separate from matter, or that the vital principle is not something different from any mate- rial substance, and resident in matter, but not of it, and placed there by the eternal and life-giving intelligence. Science gives us no positive light in regard to the origin of intelligence, though theories are abundant enough. Here, as in regard to the origin of life, we may "walk softly,” for more is unknown than is known. Yet I have no sympathy with those, on the one hand, who tell us it is irreverent to pry into the secrets of nature, for nature does not reveal her secrets; nor do I sympathize with those metaphysicians who tell us that we have no right to study what cannot be comprehended by our reason. The WHAT IS LIFE? 5 one would shut from us all matters of faith in the unseen; and the other would prevent us from investigating whatever might tend to make us distrust authority in spiritual things. The Duke of Argyll has, in substance, said, "When men tell me that I must not search for truth in a certain direction the fair inference is that they fear I may discover valuable truth hidden there.” When we try to describe life in the abstract we cannot do it with any degree of fulness or clearness. Herbert Spencer defines life to be " The continuous adjustment of internal relations to external relations.” His definition has been much praised ; but it does not seem to convey a full and complete meaning, for life seems to comprise more than a "continuous adjustment” alone. The life principle appears to be the cause of this " continuous adjustment,” for, if the life principle does not precede, this " continuous adjustment ” never takes place. This adjustment seems to be the product or consequence of the life principle. With death this "continuous adjustment” ceases. In fact the ceasing of this "continuous adjust- ment” is what we call death. Grindon says that Spencer’s definition is not that of life itself, but it merely describes certain "phenomena of life.” "A definite and clear definition of life itself is yet to be given.” The difficulty in defining the word " life ” arises from the different conceptions of what life really is. One conception may be called the metaphysical, and another the physiologi- cal. Spencer’s definition is chiefly physiological; but it seems to me that the metaphysical view which arises from our own consciousness should be considered as important as the physiological. These differences of opinion doubtless arise from different points of observation. 6 WHAT IS LIFE? Dr. Letourneau (in his Biology, p. 34) says: " The definition of H. Spencer, ' The continual agreement between interior and exterior relations ’ has the fault of being too abstract, and of soaring so high above facts that it ceases to recall them.” "It would be better to descend nearer to the earth, and to limit ourselves to giving a short summary of the principal vital facts which have been observed.” "Doubt- less life depends upon a twofold movement of decomposition and renovation, simultaneous and continuous; but this movement produces itself in the midst of substances having a physical state, and most frequently a morphological state, quite peculiar to them. Finally, this movement brings into play diverse functions in relation with this morphological state of the living tissues, habitually composed of cells and fibres endowed with special properties,” Spencer’s definition is not comprehensive enough nor clear enough to suit Dr. Letourneau, and he gives the fol- lowing definition of life : " Life is a twofold movement of simultaneous and continual composition and decomposition, in the midst of plasmatic substances, or of figurate ana- tomical elements, which, under the influence of this indwell- ing movement, perform their functions in conformity to their structure.” Some assert that the tendency of present scientific thought is towards considering life to be the result of organization. Nevertheless I must question the rightfulness of this ten- dency. An authority no less than Herbert Spencer, in answer to the question, "Does life produce organization, or does organization produce life?” states, "that function is from beginning to end the determining cause of structure.” As above intimated there is a great lack of clearness in the various meanings which different writers attach to the WHAT IS LIFE? 7 word "life.” Some regard life as an entity, or something like what the human soul is supposed to be, a something which can exist separate from matter. This is the meta- physical view. Others regard life as a " condition,” or a result of the union of a force, or something called vitality, with matter. In this connection the statement is often repeated, "Force cannot exist without matter, nor matter without force.” Thus, in regard to the question whether life is the cause or the result of organization, if life can exist separate from matter, surely life may, and doubtless should, precede organ- ization. But, if life is "a condition,” or simply a process of action, and cannot exist unless connected with matter, then organization may precede or be coexistent with the life. Lawrence says (Lectures, p. 65), " Life presupposes or- ganization, as the movements of a watch presuppose the wheels, levers, and other mechanism of the instrument.” This statement is the physiological view, and regards life as simply a " condition ” dependent upon organization. But life exists in absolutely structureless matter, and if there is no structure, where is the organization? Can there be organization without organs ? Haeckel says there are " or- ganisms without organs,” strange as this may sound. On the other hand, many believe that there can be no animal organization unless life precedes or is antecedent to the organization. Most of this difference of opinion arises (as above intimated) from the different ideas entertained as to what life in the abstract really is. Those who take the physiological view use the word life in a sense nearly equiva- lent to the verb "to live.” While we know little of the abstract principle of life we know that a certain amount of violence will deprive an ani- 8 WHAT IS LIFE? mal of life. We also know that if the blood is drawn off the life goes out with it. We also know that when the life once leaves a plant or an animal it never returns. We cannot tell the exact seat of the life. The ancient Jews were commanded not to eat the blood, " for the blood is the life.” Strange as it may seem, the blood has life in itself, and its white corpuscles are believed to be living or- ganisms ; yet we cannot say that the blood is the life itself, any more than we can say that the heart is the life. Life permeates all the vital organs, and in fact is in every part of a living body. We cannot definitely locate it in any par- ticular part of the physical system. But, if there is no par- ticular seat of life, where does death begin? Dr. Papillon says, in his work, "Nature and Life” (pp. 309 and 310), "If life is everywhere ; and if, consequently, death occurs everywhere, in all the elements of the system, what must be thought of that point in the spinal marrow which a famous physiologist styled the vital knot, and in which he professed to lodge the principle of life itself? The point which Flourens regarded as the vital knot is situated nearly at the middle of the prolonged spinal cord that is, the middle of that portion of the nerve-substance which con- nects the brain with the spinal marrow. This region, in fact, has a fine and dangerous excitability. A prick, or the penetra- tion of a needle into it, is enough to cause the instant death of any animal whatever. It is the very means used in physiologi- cal laboratories to destroy life swiftly and surely in dogs. That susceptibility is explained in the most natural way. This spot is the starting-point of the nerves that go to the lungs. The moment that the slightest injury is produced in it there follows a check on the movements of respiration, and ensuing death. This vital knot of Flourens enjoys no sort of special 9 SEAT OF LIFE. prerogative. Life is not more concentrated nor more essential in it than elsewhere ; it simply coincides with the initial point of the nerves animating one of the organs indispensable to vitality, the organ of sanguification ; and in living organisms any alteration of the nerves controlling a function brings a serious risk as to its complete performance. There is, there- fore, no such thing as a vital knot, a central fire of life, in animals. They are collections of an infinity of infinitely small living creatures, and each one of these microscopic living points is its own life-centre, for itself. Each, on its own account, grows, produces heat, and displays those char- acteristic activities which depend upon its structure. Each one, by virtue of a preestablished harmony, meets all the rest in the ways that they require, just as each lives on its own account, so on its account each dies; and the proof that this is so is found in the fact that certain parts taken from a dead body can be transferred to a living one without suffering any interruption in their physiological ac- tivity, and in the fact that many organs which seem to be dead can be excited anew, awakened out of their torpor, and animated to extremely remarkable vital manifestations.” Though life cannot be located specially in any particular part of the body, and thus we cannot say that it resides in any particular organ of the body, or that it especially resides in the blood, yet, as a part of the blood (the white corpus- cles are by some anatomists supposed to be living organ- isms), it might naturally be supposed (as the fact really is) that there should be a live blood and a dead blood, just as really as there may be a live egg and a dead egg. Live blood has heat, and is generally in a fluid state. Dead blood is generally comparatively solid, though it often remains in a fluid state in the veins for some time after death. The 10 WHAT IS LIFE ? fluidity of the blood has been shown generally to depend on its life, and not on its heat or circulation. If you draw off blood and keep it at the same temperature as the living blood, and also keep it in circulation by artificial means, it will still become partially solid, the same as if allowed to become cool. Without blood there can be no life in any air-breathing animal; and yet we are no nearer to the answer to our question, "What is Life?” when we say it resides in the blood or in the heart, or in protoplasm, than we should be if asked what kind of men live in Boston, and we should answer that they live in brick or in stone houses. If the blood is life’s house, that does not inform us what the life is. It is wonderful how the principle of life can keep the human system so many years at a temperature just right for rapid decomposition; and yet this principle counteracts all this tendency to decay, keeps the system from putrefac- tion, and causes the whole work of increasing physical strength to go on till the man attains his highest vigor. How life is prolonged, or by what abstract principle vital action is carried on, has not been revealed to mortals. In closing his address at Nashville, August, 1877, Prof. O. C. Marsh uses the following language : "In this long history of ancient life I have said nothing of what life itself is ; and for the best of reasons: because I know nothing. Here, at present, our ignorance is dense ; and yet we need not despair. Light, heat, electricity and magnetism, chemical affinity and motion, are now considered different forms of the same force; and the opinion is rapidly gaining ground that life, or vital force, is only another phase of the same power. Possibly the great mystery of life may thus be PRINCIPLE OE LIFE. 11 solved; but, whether it be or not, a true faith in science knows no limit to its search for truth.” Men have attempted to tell how life originated, and they talk of its ultimate principle, "protoplasm, or the physical basis of animal and vegetable life.” But though protoplasm is called the ultimate, were not its original elements dead matter until they received new qualities from the principle of life ? These questions have been discussed by profound students, but no voice has yet clearly answered the question, " What is Life ? ” Some assert that all life, whether animal or vegetable, is of the same nature ; and that plants as well as animals have nerve centres. Though this theory of nerve centres may not receive general assent, there are things which seem to indicate that some plants have organs of sensation. For instance, the sensitive plant will close itself on the approach of an intruder, just as a rabbit will burrow on the approach of an enemy. If you touch a certain part of the blossom of the common barberry with a pin, the stamens will close tightly around the pin, as if to hold it a prisoner. There may be, however, reason to believe that these actions of plants are caused by electricity or a like force. Bbeckel represents the mimosa when it folds its leaves as acting from the same forces in nature and the same principles as men do when they think ; but I venture the opinion that there is considerable difference in the quality of such action. However, there appears to be something like instinct in plants and trees. Plant a tree that needs moisture near a stream of water, and it will send out its roots in the direc- tion of the water. On the contrary, plant a tree that needs a dry soil in a similar position, and its roots will run away from the water, and towards a dry soil. 12 WHAT IS LIFE ? Life in the lower order of animals has a great similarity to that in the vegetable kingdom. In fact the animal and vegetable kingdoms seem to ran together, or into each other. There is an order of life which cannot with certainty be classed as either animal or vegetable, but which seems to partake of the nature of both. There is a considerable number of living organisms which may be either animal or vegetable, and I am not sure that some do not in certain respects partake of the nature of both. Some plants have motions like those of animals. Certain kinds of algae, when the cases or bulbs which hold their seeds burst, scatter the seeds, and these seeds sometimes travel around an hour or two with a rapid motion through the water like living animals. But they afterwards settle upon a rock, and grow into a plant like the parent stock. These seeds are called zoospores. Huxley (p. 160, "Science and Culture”) says: "At the present day, innumerable plants and free plant cells are known to pass the whole or part of their lives in an actively locomotive condition, in no wise distinguishable from that of one of the simpler animals, and while in this condition their movements are, to all appearance, as spontaneous as much the product of volition as those of such animals.” In regard to the supposition that some plants may have nervous centres and systems, Huxley says (p. 164, " Sci- ence and Culture”), of what is called Yenus’ fly-trap: " Touch one of them with the end of a fine human hair, and the lobes of the leaf instantly close together, in virtue of an act of contraction of part of their substance, just as the body of a snail contracts into its shell when one of its ' horns ’ is irritated.” " The reflex action of the snail is the result of the presence of a nervous system in the animal.” NERVOUS SYSTEMS. 13 It does not necessarily follow because contractility of muscle in animals shows a nervous system to exist in the animal that a nervous system also exists in plants when they have similar motions ; but Huxley says : " It suggests a suspicion of their identity which needs careful testing.” He further says (p. 165) : "The question whether plants are provided with a nervous system or not', thus acquires a new aspect, and presents the histologist with a problem of extreme difficulty, which must be attacked from a new point of view and by the aid of methods which have yet to be invented.” " Thus it must be admitted that plants may be contractile and locomotive; that, while locomotive, their movements may have as much appearance of spontaneity as those of the lowest animals ; and that many exhibit actions comparable to those which are brought about by the agency of a nervous system in animals.” He also mentions a case that occurred not long since which shows how extremely difficult it is to decide as to what kingdom certain active particles belong. Prof. Tyndall made an infusion of hay, and soon there appeared in the infusion what seemed to be living animals. He showed some of this infusion to Huxley, and asked him whether he thought the moving creatures were animal or vegetable. After examination, as they undoubtedly came from vegetable matter, Huxley decided that they were vegetable and not animal. Tyndall did not believe in Huxley’s decision, and said he would as soon " think that a sheep was a plant.” Huxley afterwards spent much time in making careful exami- nations, and finally states that he cannot "certainly say whether the creature is an animal or a plant.” But he still believes it to be a plant. 14 WHAT IS LIFE? He also quotes the eminent botanist, De Bary, when de- scribing the zoospores which cause the potato-rot, and the way they make their lodgements on the plants as they swim about: " Foreign bodies are carefully avoided, and the whole movement has a deceptive likeness to voluntary changes of place which are observed in microscopic animals.” Bear in mind that these moving zoospores are vegetable, and not animal; and that they swim in the moisture on potato-leaves as a fish would swim in a mill-pond; and after a while a spear-like protuberance comes out from the side of the zoospore and penetrates the potato-plant. Then they multiply so rapidly that in a day or so millions are grown on a single plant, and, being very minute, are carried by the winds whatever way they blow, and thus in a short time they spread over miles of territory, carrying dis- ease, or perhaps death, to the potato-plants. You can feed some minute animals (not one five-hundredth of an inch long) as well as you can feed cattle. Huxley states that you may put finely ground carmine into water in which certain kinds of animalcules live, and they will feed upon it, and when filled will become so tinged with carmine that it can readily be seen in their bodies. Their manner of feeding proves that such are animals and not vegetables. The singular nutrimental peculiarity of all living animals is, that their nutriment is taken from without, and assimilated, and what they do not need to retain is generally thrown out through excretory ducts. The taking of food is like this even with the little infusoria, which are so low down in the animal scale that they have no mouths, but take food in on all sides. This food then goes towards their centres, and from the centre there is another action towards the outside, which car- ries out of the animal what it does not need for its nutrition. 15 LOWER FORMS OE LIEE. Strange manifestations of life are found in those animals which look so much like vegetables that it is difficult to dis- tinguish the one from the other. Mr. Wallace, as quoted by Mivart (p. 45, "Gen. of Species ”), says of certain butterflies found in Sumatra which look like leaves of trees : "These butterflies frequent dry forests, and fly very swiftly. They were seen to settle on a flower or a green leaf, but were many times lost sight of in a bush or tree of dead leaves. On such occasions they were generally searched for in vain, for, while gazing intently at the very spot where one had disappeared, it would often suddenly dart out, and again vanish twenty or fifty yards farther on. On one or two occasions the insect was detected reposing, and it could then be seen how completely it assimilates itself to the surrounding leaves. It sits on a nearly upright twig, the wings fitting closely back to back, concealing the antennas and head, which are drawn up be- tween their bases. The little tails of the hind wing touch the branch, and form a perfect stalk to the leaf, which is supported in its place by the claws of the middle pair of feet, which are slender and inconspicuous. The irregular outline of the wings gives exactly the perspective effect of a shrivelled leaf. We thus have size, color, form, markings, and habits all combining together to produce a disguise which may be said to be absolutely perfect; and the protec- tion which it affords is sufficiently indicated by the abundance ot the individuals that possess it." "Some insects, called bamboo and walking-stick insects, bave a most remarkable resemblance to pieces of bamboo, to twigs and branches.” Of these latter insects Mr. Wallace says ; " Some ol these are a foot long, and as thick as one’s finger, and their whole 16 WHAT IS LIFE ? coloring, form, rugosity, and the arrangement of the head, legs, and antennas, are such as to render them absolutely identical in appearance with dry sticks. They hang loosely about shrubs in the forest, and have the extraordinary habit of stretching out their legs unsymmetrically, so as to render the deception more complete.” Thus, speaking of one of the walking-stick insects, Mr. Wallace says : " One of these creatures, obtained by myself in Borneo (Ceroxylus laceratus), was covered over with folia- ceous excrescences of a clear olive-green color, so as exactly to resemble a stick grown over by a creeping moss or junger- mannia. The dyak who brought it to me assured me it was grown over with moss, although alive, and it was only after a most minute examination that I could convince my- self it was not so.” Again, of the leaf-butterfly, he says : "We come to a still more extraordinary part of the imitation, for we find rep- resentations of leaves in every stage of decay, variously blotched and mildewed, and pierced with holes, and in many cases irregularly covered with powdery black dots, gathered into patches and spots, so closely resembling the various kinds of minute fungi that grow on dead leaves that it is impossible to avoid thinking at first sight that the butterflies themselves have been attacked by real fungi.” There are certain grasshoppers which look almost exactly like leaves. Instances of a similar nature might be multi- plied, showing in what wonderful ways nature exhibits the varieties of life. Probably the fact that animals or insects mentioned above look so much like vegetables may be the means of preserving their lives from natural enemies; and hence be the indirect means of keeping the species in existence. 17 STRANGE FORMS OF LIFE. H. L. Fairchild, in "Popular Science Monthly” for September, 1882, writing of the means of defence, of which breaking apart may be an example, says : " Oddest of all defensive methods is that of snapping off the tail. The blind-worm, or the slow-worm, is a little, snake-like lizard, common to the Old World. When alarmed, it contracts its muscles in such a manner and degree as to break its tail off at a considerable distance from the end. But how can this aid it? The detached tail then dances about very lively, holding the attention of the offender, while the lizard him- self slinks away. For a considerable time the tail retains its capability of twisting and jumping every time it is struck. The lizard will then grow another tail, so as to be prepared for another adventure. There are other lizards which have similar power, though in a less degree. The American glass-snake, so called, is one.” The limbs of certain reptiles, and of some other animals grow like vegetable shoots. If a serpent loses his tail he can have another by growth. If a lobster loses a claw, or a lizard a leg, another will grow to replace it. If a snail loses his head even, another will grow on in course of two or three months. Cut some animals into two or more pieces and each part will grow into a separate individual. Take the polype for instance, cut that into several pieces, and each piece will grow into an individual organism like the original one. If you cut off the part which may be called its tail from that piece will grow all the other parts of the body, till it completes itself, mouth and all, like the original animal. Huxley states (p. 85, "Origin of Species ”) : "And so far does this go that some experimentalists have carefully examined the lower orders of animals, among them the Abbe Spallanzani, who made a number of experiments upon 18 WHAT IS LIFE? snails and salamanders, and have found that they might mutilate them to an incredible extent; that you might cut off the jaw, or the greater part of the head, or the leg, or the tail, and repeat the experiment several times, perhaps, cut- ting off the same member again and again ; and yet each of those types would be reproduced according to the primitive type ; nature making no mistake, never putting on a fresh kind of leg, or head, or tail, but always tending to repeat, and to return to the primitive type.” But if you cut off a man’s finger one will not grow to replace that. Life in the lizard’s leg, the lobster’s claw, and in the serpent’s tail is like that pertaining to the very lowest types of animals. This also resembles life in the vegetables, in the skin of the higher animals, and in the nails or hoofs of certain animals. Herbert Spencer remarks : " The highest animals repair themselves to a very small extent, mammals and birds only in the healing of wounds. The power of reproducing lost parts is the greatest where the organization is the lowest.” The lowest animals are like certain plants which can be divided again and again, and each separate part will grow into a plant like the original one. Plough through a horseradish bed, and the pieces that are carried away by the plough and left in other places will grow into perfect roots. Often this is the cause of considerable trouble to the gardener. A strange thing connected with animal organisms is the appearance of life excited by a galvanic battery after death. The length of time that these appearances of life will continue is generally greatest in the lower animals. Take a common frog, cut it in two, and hours afterwards, STRANGE PHENOMENA. 19 on the application of the battery to the backbone, the part will jump as if alive. Dr. Bastian says (p. 27, " Beginnings of Life ”) : " Durino- winter the muscles of certain fishes and certain O reptiles have been known to contract for a week after death; though in birds and mammals this property of the voluntary muscles disappears after a few hours.” From the researches of Nysten upon the bodies of decapitated criminals, it appears that in man, as in the lower animals, a certain order is observed amongst the different muscles of the body in the loss of this vital property. Contractions from electrical stimuli ceased in the left ventricle of the heart after forty- five minutes; in the muscles of the extremities, after seven hours; and last of all, in the right auricle of the heart, which on this account had been previously spoken of by Galen as ultimum moriens. In one instance Nysten found that this portion of the human heart could be made to contract sixteen and a half hours after the death of the individual.” When a man is 'decapitated we consider him dead. But query : lias all life actually left the right auricle of the heart, so long as galvanism will cause it to contract ? A considerable portion of a man’s body may be dead before the brain dies ; why also may not one part of the vital organs even be dead before all the heart dies ? Dr. Beale says (p. 261) : " The life of a man or the life of an animal is something very different from what is termed the ' life ’ of a white blood-corpuscle, or of a mucus, or pus corpuscle; inasmuch as many hundreds of white blood-corpuscles, or elemental units of the tissues, might die in the man, without the life of the man being affected. Moreover, the man himself might perish, and some of his living particles remain alive.” 20 WHAT IS LIFE? A man is not always dead when all outward signs of life have disappeared. Instances are not uncommon where per- sons are resuscitated after they are supposed to be dead, as in cases of persons apparently drowned. An acquaintance of mine once apparently died of a contagious disease, and preparations for burial were being made. The man told me that he was conscious of what was going on, but that he could not exhibit any signs of life. After a while one of the attendants thought he detected signs of life, and the prepara- tions were postponed, and the man lived. In a case like this, decomposition only would seem to be certain evidence that the man was really dead. In "Nature and Life” (pp. 325 and 326), Dr. Pa- pillon says : " A zealous philanthropist quite lately gave a sum for a prize of twenty thousand francs to the discoverer of an infallible sign of death. Doubtless the intention is excellent, but we are safe henceforward in regarding the sex- ton’s work without alarm; the signs already known are clear enough to prevent any mistake, and to make the fatal risk of premature burial impossible.” "We must point out in the first place the immediate signs of death. The first and most decisive is the absolute stop- page of the heart’s pulsations, noted for a duration of at least five minutes, not by the touch, but by the ear. ' Death is certain,’ says the reporter of the Commission named in 1848 by the Academy of Sciences to award the prize of competition as to the signs of true death, ' when positive ces- sation of pulsation of the heart in the subject has been ascer- tained, which is immediately followed, if it has not been preceded, by cessation of respiration and of the functions of sensation and motion.’ The remote signs equally deserve attention. Of these, three are recognized : corpse-like rigid- SIGNS OF DEATH. 21 ity, resistance to the action of galvanic currents, and putre- faction. As we have already seen, rigidity does not begin till several hours after death ; while general and complete dis- appearance of muscular contractility, under the stimulus of currents, and last of all, putrefaction, are only manifest at a still later period. These remote signs, particularly the last, have this advantage, that they may be ascertained by those unacquainted with medicine ; and it is very well to pay some attention to them in countries where physicians are not charged with the verification of the disease, but they are of no importance wherever there are doctors to examine the heart with instruments, and to decide promptly and surely upon the death from the complete stoppage of pulsation in that organ.” The question, what death really consists of, is a very inter- esting and profound one. Prof. Joseph Be Conte, in his treatise on the " Correla- tion of the Vital with the Chemical Forces,” says (p. 200) : "As organic matter is so much matter taken from the com- mon fund of the matter of earth and air, embodied for a brief space to be again by death and decomposition returned to that common fund, so also it would seem that the organic forces of the living bodies of plants and animals may be re- garded as so much force drawn from the common fund of physical and chemical forces, to be again refunded by death and decomposition, —yes, by decomposition ! We can under- stand this. But death ! Can we detect anything returned by simple death ? What is the nature of the difference between the living organism and the dead organism? We can detect none, physical or chemical. All the physical and chemical forces withdrawn from the common fund of nature, and em- bodied in the living organism, seem to be still embodied in 22 WHAT IS LIFE? the dead, until, little by little, it is returned by decomposition. Yet the difference is immense, it is inconceivably great. What is the nature of this difference, expressed in the formula of science? What is it that is gone, and whither is it gone? There is something here which science cannot yet understand. Yet it is just this loss which takes place in death and before decomposition, which is in the highest sense the vital force.” But equally great is the change from death to life. At one moment matter is inert, or dead, and in another it is alive, without the least chemical change that we can detect. This change is instantaneous. The line believed to exist between the living and the dead can be crossed instantly ; but how wide is the gulf, and how immeasurably deep the chasm ! Well may we ask in wonder, What is this force or energy which makes this wondrous transformation ? Life has many varied forms and strange shapes, especially when it is hard to tell whether it is animal or vegetable. Some animals are planted like vegetables. Others, like the clam, live and grow without seeming to travel; though I believe as a matter of fact, the clam does change its dwell- ing-place. There are also other striking similarities between animal and vegetable life. Trees grow by secretion, as well as animals. In fact, the white corpuscles in the blood of a man (which are about one twenty-five hundredth of an inch in diameter) are almost identical in chemical constituents with the corpuscles in the sap of certain trees. These white corpuscles in the blood of a healthy man are about one to three hundred of the red, and are somewhat larger than the red corpuscles. In some dis- eased persons, however, the white become equal in number to the red corpuscles* (Bastian, p. 225.) SIMILARITY OF ANIMAL AND VEGETABLE LIFE. 23 Thus in such diseased persons the blood approaches in its chemical composition the sap in the trees. Girdle a tree so that the sap cannot go up under the bark, and the tree will die, as an animal will die if you stop the circulation of its blood. The blood of the tree circulates under the bark, and the little tubes which carry the sap to its leaves correspond to the veins of a man. The leaves of a tree are its lungs, and they also take in some of its nutriment; they inhale carbonic acid gas, which man exhales. There is a difference, however, in the way a tree shows its death. It does not fall down at once, like an animal; but the first sign of death is the withering of its lungs, or leaves, or their fall. Neither is the decay of a tree accompanied by that offensive odor which accompanies decaying animal mat- ter ; though in some decaying vegetables, as the cabbage and the potato, the odors are anything but sweet. However,when you attempt to distinguish the lowest orders of animals from vegetables, it is very important that the odors of decay should be duly noted; for if they are not, it may be impossible to determine whether they are animal or vegetable. The sponge, for instance, on the rocks and shells where it grew, was for a long time supposed to be a vege- table ; but when odors from decay and from burning were noticed they were so distinctly animal that the sponge is now conceded to be animal, and not a vegetable. There is a similarity of construction between animals and vegetables. The tree has a bark for a covering, and the animal, a skin. Cut the bark of a tree, and the sap, or the tree’s blood, will flow. So also, cut the skin of an animal, and some of the vital fluid, or blood, will flow. But cut the limb off a tree, and it may not injure its vigor. It may 24 WHAT IS LIFE? make it even more vigorous. Certain trees and vegetables thrive all the better for priming. Not so with the higher order of animals. By cutting off their limbs a definite loss of power occurs. Cut a tree down, and it may sprout and become a vigorous tree again. But of man, Job said, "As the waters fail from the sea, and the flood decayeth and drieth up, so man lieth down, and riseth not: till the heavens be no more, they shall not awake, nor be raised out of their sleep.” Men and animals decay with age, and so also plants and trees. There is a turning-point in the lives of trees and animals. Perhaps, after a vigorous life of from two hundred to five hundred years, the highest vigor of a tree may be reached, and then, like an old man, it may be on the down-hill of life. There are also health and disease in both plants and animals. Both need food. The tree must have earth and moisture, or it will die of hunger and thirst, like an animal deprived of nourishment. How similar the origin of fowls and the oak ! The changes of the chicken in the shell, like the germ in the acorn, can be observed during its early development, and until it bursts its shell. The chick has nutriment in its crop from the yolk of the egg to sustain it until it has strength to go in search of other food. Quite similar is the germ of the acorn before it bursts its shell. The acorn itself furnishes food to nourish it until its roots can go down into the earth in search of other nour- ishment. How similar this to the mammalian mother, who carefully nurses her young till it can take other food! There is also in each of these cases an expenditure of en- ergy, and this energy must be supplied by combustion from SIMILARITIES. 25 within until it can get nourishment from without. Thus, as we might suppose, the egg during the season of incubation grows lighter in weight. So likewise the acorn sprouting loses much of its solid substance in feeding the shoot. Like- wise the caterpillar, when it comes forth a butterfly from its chrysalistic state, is much lighter than when, as a caterpillar, it entered the chrysalis. In some cases nine-tenths its weight is lost during development. The energy required for de- velopment in this case must be supplied from combustion within. So, also, all energy of development must be sup- plied from within when it cannot be had from without; for Nature will not be cheated out of her just dues ; and she will supply no energy, no development, except it be paid for in a legal way. No human government can more strongly demand " legal tender ” than Nature does. How strangely, also,will Nature assert herself, even in the youngest creatures ! Place the eggs of a duck under a hen, and let her hatch them out. Why do the little ducks so soon take to the water, where the hen, their foster-mother, does not dare to go ? Who taught the little duck that its foot was shaped just right for swimming ? Why does it not heed the example and instructions of the only mother it has known, and keep away from water ? Why is the whole nature con- tained in the egg from which it comes forth? "From a bad egg comes a bad crow,” is a familiar quotation. Who but the great Author of all life can fully explain all the laws of heredity or descent? Trees and animals have a similarity of structural organi- zation. The animal has a bony skeleton, to give it form and strength. Even the tortoise has a skeleton ; but that is on the outside instead ,of inside. So the tree has in every year’s growth a part that is stronger and harder than the 26 WHAT IS LIFE? other part; and it has also cells, through which moisture and other nutriment circulate. Trees breathe through their leaves, and also gather some nourishment through them ; and light and heat are as necessary to trees as they are to animals. If you keep a tree constantly stripped of its leaves, it will die, as surely as a man will if his lungs are so filled or so im- paired that he cannot get oxygen to keep up the vital fires. With man life means action. We speak, and justly too, of a man of no energy as a lifeless character; for he does not show qualities that we have a right to look for in a being endowed with life. Even a lazy man will speak slightingly of another lazy man. Again, observe the similarity of physical structure in man and birds and quadrupeds: how the fore legs of quadru- peds and the wings of birds correspond to the arms of men. Yet in some parts of anatomical structure there is a wide difference between birds and men, especially in the position and shape of their lungs, and in the construction of their bones. Bones of birds are more hollow, and thus are made as light as possible for the strength required. Their breathing-apparatus is more generally distributed throughout the body than in men or quadrupeds. A consid- erable portion of the bird’s lungs is near the outside, and directly under the wings; hence a pressure under the wings of a bird on each side of the body will stop its breath, and death will generally ensue within one minute. But, unlike men, birds can breathe through the hollows in their bones. H. L. Fairchild, in "Popular Science Monthly” for April, 1882, says ; " Except in water-birds, the hollow bones also contain air, and by their connection with the lungs respiration BIRDS AND QUADRUPEDS. 27 can be continued through an opening in the arm or thigh bone, although the windpipe may be tied.” I will now mention some curious phenomena connected with the development of life through a mixture of races : One of the strangest characteristics of living things appears in what are called hybrids. These hybrids may be either animal or vegetable. They are the progeny of what appear to be two different species of plants or animals. I say appear to be different species, for I do not believe that radically dif- ferent species can interbreed. Hybrids do not interbreed between themselves. The offspring of the ass and the mare is called a mule. The horse will also interbreed with the zebra and the quagga. But horses, asses, quaggas, and zebras belong to different branches of the same family. Progeny from the inter- mixture of either of these are infertile among or between themselves, though they sometimes interbreed with the original stock. The most singular trait of the cross between the horse and the ass is the difference between the mule and the hinny ; the mule being the offspring of a jackass and a mare, and the hinny the offspring of a stallion and a she-ass. Now one would naturally suppose that the offspring of a she-ass and a stallion, and a he-ass and a mare, would be alike ; but they are not; the mule has the head, ears, and tail of the ass, and the body of a horse, but brays like an ass ; while the hinny has the head, ears, and tail of a horse, and the body of an ass, but neighs like a horse ; so strangely different in hybrids are the qualities transmitted by the male and female parents. The dog and the fox will interbreed, but their offspring are infertile with each other, though they may interbreed with 28 WHAT IS LITE ? the parent stocks. The wolf and the dog, being of a nearer relationship, will interbreed, and their offspring are fertile, and rear a race of wolf-dogs. This ability to propagate a race easily, in a great measure indicates the nearness of the relationship between races which seem to be different from each other. SIMILARITIES IN ANIMALS. 29 CHAPTER 11. SIMILARITIES IN LIVING CREATURES. I wish now to call attention to certain similarities, both physiological and instinctive, which pertain to nearly every class of animals, and also to the harmonious and unvarying action of the laws of nature in connection with all animated existences. General rules apply to many characteristics of nearly every variety of living beings. The brain, stomach, heart, liver, how very similar their operations in different animals ! But the heart and stomach in different orders of animals are very differently constructed. Hunter, in his classification of animals, places,— first, " mammalia and birds ; having a heart with four cavities. Second, reptilia and amphibia; having a heart with three cavities. Third, fishes and mollusks (pars) ; having a heart with two cavities. Fourth, articulated animals; having a heart with one cavity. Fifth, medusas; having the heart and stomach identical.” Notwithstanding these radical differences of construction the circulation of the vital fluids and the action of the vital organs have a wonderful similarity. How strangely alike are men and animals in their affec- tions and in their anger ! What strange variations of form and habits, and yet what similarity of tastes ! Brutes appear to have their seasons of hilarity, depression, and even sorrow. How piteous the moans of a dog that has lost his 30 WHAT IS LIFE? master; how joyous at meeting an old acquaintance; how like, in some respects, a playful child and a playful kitten ! Each will cry from a sense of loneliness, and each likes to be caressed. How like in their industry are active human beings and bees ! Each improves the time in active labor. Each has a disposition to accumulate against the time of need. Bees, like men, when they have accumulated property are dis- posed to keep and defend it. What a remarkable instinct (or shall I call it intelligence?) bees show in the con- struction of their comb, the house for their young, and the storehouse of their food ! The mathematical proportions of these houses are as correct as those in any human habita- tion. Their hexagonal shape, and pyramidal bases placed as they are, make the strongest possible structure consider- ing the amount of material used. It has been stated that the bee is so made physically that it could not make its comb in any other shape; but I do not believe this statement, for I think the contrary can be shown. Obstructions have been pur- posely placed where bees would like to build their comb ; and, to avoid these obstructions, on the one side they have built their cells larger externally than at the bottom of these cells; but on the other side they made the orifices of the cells smaller than the cells were at the bottom, and thus built the faces of the comb on a regular curve instead of straight, but still kept regular mathematical proportions. This seems to show intelligence of no mean order. But suppose the previous statement, that the bees’ physical construction is such that they can build their comb in only one way, were true; then what intelligence so constructed the bees themselves that they can BEES 31 make their comb only in correct mathematical proportions? Did this happen fortuitously ? I do not suppose any man ever directed the construction of a public edifice, who more thoroughly adapted all its pro- portions to secure the proper strength, than do these bees, taught by the supreme intelligence, or by nature. Some- times they show remarkable intelligence in the construction of defensive works to keep out moths that might destroy their young, and themselves even, if these moths could get access to their homes. It is a pity that human beings are not better imitators of the bees in this respect. The organization of the bee is a very complex one, with a delicately organized nervous system; in fact the very anatomy of the bee indicates a high degree of intelligence. If man has been evolved, or developed from lower animals, as Darwin supposes, we might reasonably expect, from the highly complex and intelligent organization of the bees, that they would be our near relatives. But Haeckel can find no common ancestors without going back through thirteen grades to the primitive worms, and rather despond- ingly remarks (p. 252, vol. 1, "Evolution of Man”): " Unfortunately, we lose by this the relationship which might otherwise connect us with termites, ants, bees, and other virtuous members of the articulate class. Among these insects are many well-known patterns of virtue, which the fable-wrriters of old classic times held up as examples for men. In the civil and social arrangements of the ants, especially, we meet highly developed institutions which we may even yet regard as instructive examples. But unfor- tunately these highly civilized animals are not related to us.” Prof. Oscar Schmidt says (p. 28) : " Hours do not 32 WHAT IS LIFE ? suffice to describe the structure of the bee. Even externally, its body, which possesses so highly complicated a structure, promises a rich development of the interior. The mandu- catory apparatus can be rendered comprehensible only by comparison with the oral organs of the whole insect world. The various divisions of the alimentary canal are each pro- vided with special glands. The rich psychical life, all the actions which imply intelligence, calculation, and perception of external situation, are rendered possible by a highly devel- oped nervous system, and the marvellously complex sensory organs with it, of which the eyes are especially remarkable. Independently of the generative organs, consisting of mani- fold parts of greater or less importance, the history of the multiplication and development of the bee demands a study of itself.” Thus, from the very complexity of the bee’s structure, we might naturally look for the high degree of intelligence which bees manifest. The higher order of animals seems to possess considerable intelligence. The ant (spoken of above) has been com- mended for its activity, and the sluggard has been advised to imitate it. But when we speak of intelligence in animals we are told that they work entirely by instinct. lam not, however, willing to admit that instinct accounts for all the manifestations of intelligence they exhibit. Ants appear to have a kind of language by which they communicate with each other, and in such a way as to be perfectly understood. Who has not seen signs of intelligence among dogs, and to some extent reason ? They also appear to have certain sense of right and wrong. Some years since, at Bye, N.H., two large dogs went together about two miles from their homes, in the night- MORAL SENSE IN ANIMALS. 33 time, to where a flock of sheep was kept, and killed several of the sheep. They did this more than once; and these destroyers could not be detected for a long time, but were at last discovered; and the first thing that attracted attention and raised suspicion against them was their guilty appear- ance on days succeeding their bloody excursions. A watch was set, the dogs were detected, and paid the penalty with their lives. It may be answered that these dogs did not have any sense of right or wrong, but that they feared punishment, and this made them appear guilty after their wrong-doing. But why this fear, when no one saw them kill the sheep ? If we suppose they feared that some one saw them, does not this very fear imply a species of reason ? Instances of a similar nature might be multiplied, many of them coming under my personal observation, which show that dogs have in their mental make-up much that is akin to reason, and (without indorsing the Darwinian theory in every respect) I think that their actual relationship to the genus homo in their mental characteristics may be nearer than some are williim to acknowledge. O O Agassiz goes beyond this in his book on the classification of animals (pp. 96 and 97), and writes as follows : " When animals fight with one another, when they asso- ciate for a common purpose, when they warn one another in danger, when they come to the rescue of one another, when they display pain or joy, they manifest impulses of the same kind as are considered among the moral attributes of man. The range of their passions is even as extensive as that of the human mind, and I am at a loss to perceive a difference of kind between them, however much they may differ in degree, and in the manner in which they are expressed. The 34 WHAT IS LIFE? gradations of the moral faculties among the higher animals and man are, moreover, so imperceptible that to deny to the first a certain sense of responsibility and consciousness would certainly be an exaggeration of the differences which distinguish animals and man. There exists, besides, as much individuality within their respective capabilities, among animals, as among men, as every sportsman, every keeper of menageries, and every farmer or shepherd can testify, or any one who has large experience with wild, tamed or domesticated animals.” If dogs had the gift of speech doubtless they would exhibit intelligence which would surprise us, for they might learn from each other facts of history, and a thousand other things of which we now suppose them to be profoundly ignorant. Look at a human infant! If it was not for knowledge transmitted to it through spoken, written, or sign language, how high would it be likely to rise in the scale of intelli- gence? It is true its brain is large, but that very size of brain needs attention; and the child must have culture, else bad results will be likely to follow. Notwithstanding what has been written to show that highly elaborated languages with nearly perfect grammatical structure, do not necessarily indicate any particular revela- tion of language to man (and while I am willing to admit that all languages in their inception may have been very simple), yet I am constrained to consider the power of speech to be a direct gift to man, as the crowning intelligent being on the earth. Moreover, the Creator has given to man vocal organs differing greatly from those of all other animals ; so that, even if the dog or the horse had as large and as active a brain, and were as well constituted mentally MEN AND APES. 35 as man, jet they would not be able to articulate any known human language. Thus the Creator has not only endowed men with large brains but also with suitable physical organs, through which their thoughts can be communicated, and thus the experience of one may be the guide of the many. But though we may be complimentary to the intelligence of the higher animals, let us understand that the gulf which separates the brute from the human is very wide, deep, and in fact impassable, so far as any light from science has shown. The development of the highest order of the brute creation is upon a radically different basis. Take the young of the highest anthropoid races at the time of birth and compare it with the human infant. No one species of apes is in every respect nearest like the human species. In some respects the orang is nearest, and in other respects the chimpanzee, but for the purposes of comparison take the latter. At the time of birth, the infant chimpanzee looks (in some respects) more intelligent than the human infant. But as each develops in its natural way a wide divergence appears. The upper part of the forehead, which represents the reasoning faculties, fills out and becomes strongly devel- oped in the human infant as it grows older, while in the infant chimpanzee, the forehead, instead of becoming fuller, begins to recede, and the shape of its brain seems to indicate a tendency towards less rather than more intelligence as its body becomes developed. So very marked is this divergence between the infant chimpanzee and the human child as each grows older that it can be accounted for only by admitting that the great intelligence which presides over all nature, and over all the laws of birth and development, has from the very first fixed this radical difference. This filling out of the human fore- 36 WHAT IS LIFE ? head before the infant can talk shows that it has inherited something through its very constitution which tends towards thought and reflection; while the receding forehead of the anthropoids as they grow towards maturity show that they inherit a constitution tending exactly in an opposite direc- tion. This difference will doubtless forever remain. M. Quatrefages, in his "Human Species,” says (p. 379) : "In drawing comparisons between men and apes, the sphe- noidal angle, discovered by M. Yirchow, studied by M. Welker, and which, thanks to M. Broca, may be measured without making a section of the skull, presents special in- terest.” These experiments and measurements show that in man the average sphenoidal angle measures, in infancy, 141 degrees, but in the average adult 134 degrees, showing a decrease of seven degrees in the size of this angle, from infancy to adult age. But, on the contrary, in apes, —take the sajou for instance : At birth this angle measures 140 degrees, or one degree less than in the human infant; but at mature age it measures 174 degrees, or an increase of 34 degrees. In the orang, at birth this angle measures 155 degrees, and in the adult 174 degrees, or just the same as the sajou, but showing an increase of 19 degrees between infancy and adult life, giving an average increase of degrees of this angle in the apes. But in the average human this angle decreases 7 degrees from infancy to mature age. But, notwithstanding human superiority to the speechless animals, our domestic animals are entitled to kind and con- siderate treatment. Life even in the brutes is a wonderful thing. If life is merely a mechanical operation, as some suppose, why should a horse flee from a wild beast on account of fear ? What other mechanical operation has fear ? 37 WHENCE LIFE-GIVING POWER? Who ever knew a steam-engine to turn out of its course for any beast from fear? Still, there are many things about a steam-engine that much resemble muscular action of animals. o The active energies of each are supported by combustion. The combustion of a peck of oats in a horse develops power, just as really as a peck of coal burned under the boiler of a locomotive. But what a difference in the results ! The oats are turned not only into muscular and motive power but into tissues and nerves that have sensations ; and they also furnish food to repair wasted tissues. But the combustion of coal under a boiler repairs no wasted tissues, and builds up no body that can feel pain, or emotions of fear, joy, or sorrow. It takes the vital principle to make combustion perform this double duty. As the physical system is supported through combustion, and largely receives its strength through this, several ques- tions naturally arise. First, Whence originates life-giving power? Can this power be derived from the purely mechanical laws of nature? Or is there a force, whether personal or impersonal, behind, or antedating the laws of nature, which originated and ordained these immutable natural laws, and from which comes this life-giving power in accordance with these im- mutable laws ? The varieties of plants and animals are almost infinite in number; and yet all these can be arranged in a few classes, and in some respects they are all constructed and developed upon one general plan. Every variety of living thing seems perfectly formed for the purposes of its existence. How does all this happen to be so ? Did all this happen without purpose, or without what (for want of a better term) we call intelligent direction? 38 WHAT IS LIFE? Notwithstanding all the dust thrown by those who repeat the statement that the theory of evolution annihilates the idea of design in creation, the fact still remains that some power has acted in a manner which we are accustomed to call intelligent, and this power lies back of all the phenomena of evolution, and the process of evolution is one manifesta- tion of the way in which this power has been and is still working. If we deny purposive direction in this, we might as well assert that Handel’s grand oratorios or Beethoven’s sublime symphonies were composed and arranged by throw- ing mud-balls at random on a musical staff, and then writing the notes where these mud-balls struck. More than 1,900 years ago, Cicero, in substance, asked what would be thought of a man who should assert that a valuable book could be written by throwing lettered blocks into the air and allowing them to fall at random, with the expectation that they would so fall and arrange themselves as to compose a nice poem or a logical argument? Nice poems and logical arguments are not produced without careful, intelligent thought; nor is it likely that as wonderful and complex things occur in nature without purposive direction. In nature there is everywhere as much harmony, and as real an exhibition of intelligent methods, as is seen in the production of great musical com- positions or in logical arguments. Everywhere not only harmonious arrangements are found but also the nicest mathematical proportions, whether we look among plants and animals, or to the planetary systems. As much care seems to be given to the construction of tiny insects as to the balancing of worlds and systems of worlds, which go on their ceaseless rounds through the immensity of space, and always in perfect order. If we doubt that these nicely harmonious arrangements DESIGN IN CREATION. 39 were made by an infinitely wise being, and suppose they do not indicate the intelligence and power of a creator, by what magical power do they happen to exist? Why may we not as well suppose that the telescope of Lord Bosse made itself, or that it was constructed without intelligent instruction, as to suppose that even the eye of a fly made itself, or was con- structed by nature without a superintending, creative and intelligent power? Why may we not as well suppose that the finest coins ever struck olf in a mint simply happened to fall in that shape without a die to give them shape or form ? There can never be an event under the laws of nature without a cause, and this cause must of necessity be of a nature related to this event, and must be powerful enough to produce it; and no effect can be greater than its cause. The less (except through outside help) can never produce the greater; so, not the smallest insect lives which was not caused to exist by a power capable of producing life, and also by a power above our comprehension ; for, if we could comprehend the full action of this power, we might our- selves originate life. Scientific research has not yet demon- strated how life originally came into existence on the earth. But every man knows it does exist on the earth, and this not without a cause, and a cause also that is equal to the event, viz., the production of life. Those who believe in the mechanical and chemical theory of life think they find in nature alone all the power neces- sary to evolve life, or to raise inorganic matter to the plane of organic, or living matter. Though to my mind it is extremely unphilosophical to attempt to account for the origin of life without recognizing the existence of an almighty, eternal, and intelligent being as the original 40 WHAT IS LIFE? Creator, yet the Creator works so largely and so unerringly through secondary causes, or through the laws of nature, to such an extent, that in one sense I do not wonder that some never look beyond these secondary causes, but recognize them as existing eternally, and hence in their minds they dispense with any idea of an original great first cause. They do not recognize in this cause an acting, thinking, eternal intelligence. The manifestations of life on the earth furnish us with all that we know for a certainty of any life. Vegetable life is largely dependent upon one of these secondary causes, viz., the sun. Blot out the sun, and all life on the earth would cease ; nay, more, the planets would rush into space no one knows where, nor to what ruin. The rays of the sun falling upon trees and plants contribute to their growth, and in fact to a considerable extent feed them. Then plants and vegetables furnish food to herbivorous animals, and these in O turn furnish food to carnivorous animals. But notice this : carnivorous animals and birds of prey prefer to feed upon plant and grain eating animals. (They like to take food one remove from vegetables, but seldom desire to take it two removes from vegetables.) Thus, flesh-eating animals are not generally accustomed to feed upon other exclusively flesh-eating animals. A singular and distinguishing trait or characteristic of nearly every species of birds of prey is that the female is considerably larger and stronger than the male. In almost every variety of hawks the spread of the wings of the female is from two to four inches greater than that of the male, and they are correspondingly stronger. The female eagles weigh, on the average, about a pound more than the male eagles, and they are in a corresponding degree more powerful. I BIRDS OF PREY. 41 have never heard of eagles feeding upon the flesh of other flesh-eating birds ; but they rob fish-hawks of fishes which they have caught for their own use. Ben. Franklin did not like this habit, and was much opposed to putting the eagle on our national coat-of-arms, for, said he, "the eagles do not get an honest living.” However, the eagles are a type of the rapacity, heartless- ness, and cruelty of carnivorous animals. They live by the seizure and death of others. But this again, in a figure, is a type of the subsistence of living creatures in general. Nearly all live by the destruction or assimilation of other orders ; and some will even eat others of their own species. Plants live upon inorganic, and animals upon organic nature. It may be said that when big fishes eat little ones this is a general type of the subsistence of all animated existence. The large tree, " monarch of the forest,” overtops and stunts all other vegetation within its reach. It must be fed, and hence withholds nutriment and sunshine from weaker vegetation. So with animals, even to the highest, man. The great and strong generally take from the small and weak; and there is no reasonable hope that a similar con- dition of things will not remain so long as the present order of things exists. We dream of the millennium, and indulge other fond hopes, and to some extent there may be improvement, and Hope says, "there is a good time coming.” But the character of human nature will ever remain substantially the same. The communist dreams of the time when all men will have equal privileges, and all be in a certain sense equal; but so long as nature favors one man with more intelligence than another, just so long will one be superior to another; and as long as one is superior, so long 42 WHAT IS LIFE ? will he not only claim a preeminence, but will obtain a certain eminence. There are, however, some noble exceptions to this general rule, especially when the learned instruct the ignorant, the morally strong try to lift up and strengthen the morally weak, and the physically strong defend the defenceless, and the wealthy give of their abundance to comfort the indigent. Though a grasping nature inheres in all men, scarcely any are totally devoid of sympathy, and in some the spirit of kindness is very strongly developed. These show that, after all its defects, human nature is not entirely devoid of godlike sympathy. But we must look facts squarely in the face ; and some of these facts are not of such an assuring nature as we might desire. Philanthropists look forward to the blissful time when wars shall cease, and when the knowledge of the laws which govern health will be so well understood that there can be no wide-spread epidemics, and when the average life will be much longer than it now is. This is well as a sublime dream ; but what do stern facts indicate? If wars cease, and the average of life is greatly lengthened, population will wonderfully increase. Exceeding great numbers must be fed, and well fed too, or pestilence will stalk abroad, and again diminish the number of the living. But if pestilence does not come, and food is short, the hungry must and will have food, and the rule, get food "honestly if you can, but get it,” will be applied. Man is a lighting animal, and will always so remain. Those in possession of fertile and pro- ductive fields will not give them up without a struggle; hence wars will be inevitable. When we consider what the present population of this NATURAL INCREASE OF LIFE. 43 little globe would have been in the regular course of in- crease if none bad lost tbeir lives by accident, wars, or pestilence, we see that the present power of food production by the earth would not suffice to feed one-tenth of the number that would be here. Under favorable circumstances races of men increase very rapidly. Had it not been for untimely deaths from famine, pestilence, accidents, or wars, there would not be standing-room on the whole earth for the immense number of human beings which would now be in existence. From one single pair, providing each couple should pro- duce four children, within thirty generations, or in less than one thousand years,—the living descendants would number near three thousand millions, or more than twice the present number of all the human inhabitants of this globe. Doubtless food production can be increased greatly beyond our present needs ; but let the present population be ‘in- creased one hundred-fold, as it would be within a thousand years if the dreams of certain philanthropists could be real- ized, and then the bosom of mother Earth could not furnish the needed supply of food. There is such a thing as a balance of forces in nature, and a limit to the supplies for both vegetable and animal life. Certain birds and beasts of prey, which men are anxious to destroy, are doubtless very useful in the economy of nature. Take owls, for instance. What good do they do ? They often destroy the farmer’s chickens, and this is placed to their debit; but, if we credit them with the great numbers of mice and other injurious vermin which they destroy, we shall find a large amount to be placed to their credit. It is doubtful if any living creature has been made in vain, although some may question 44 WHAT IS LIFE ? what good can come from the existence of certain insects, the mosquito for instance, or certain venomous serpents. We talk of the survival of the fittest. Doubtless, in a general way there is truth in the doctrine of such survival; but we might also say the survival of the most fortunate; for how often do the strongest succumb to accident, or un- foreseen calamities ? A large proportion of humanity is carried along by force of circumstances, as wood is carried by currents of water, or as straws are carried by the winds. It is true, that some men seem superior to circumstances, and appear to make circumstances serve their purposes, and weave the web of life’s actions according to their desires ; and some woi’k themselves into other currents ; but it is doubtful if even the most fortunate reach anywhere near the goal of their ambition. There are always other worlds to conquer, or, if we cannot find them, —like Alexander, we weep because we cannot find others to conquer. But it is asked, Why not make laws to restrain the grasp- ing propensities of strong men, and so protect the weak that all may stand financially upon a level ? When men can stop the natural ebbing and flowing of the tides, then, and not till then, will they be able to turn back the tide of the tendencies of human nature. Suppose, for instance, laws were made for an equal distribution of prop- erty, and carried into effect, how long would it be before the distribution would be as unequal as it is now ? On account of the improvidence of many who never before had any spare money, and the freeness with which they would spend it, doubtless there would be given to business an impetus such as it never before received, and immense fortunes would in a very short time be acquired by shrewd financial operators. Probably within twenty years there would be men with LIVING UPON OTHERS. 45 greater fortunes than any man now possesses. But why not make laws which will render such an accumulation impossible ? When we make laws which prevent men from honest accu- mulation we shall take away the greatest stimulus to activity, and the remedy would be much worse than the disease. The lazy and the improvident will alvrays be found in human society, and it is questionable how far it is the duty of the industrious and frugal to help the indolent, especially when such assistance tends to encourage indolence and shiftlessness. Look at the immense numbers which society has to main- tain on account of habits of inebriation. By what law of right do the intemperate and slothful live upon the temperate and frugal ? It is said that whatsoever a man sows, that shall he also reap ; and, if one will sow to rum, what can he expect to reap but drunkenness and the untold evils which it brings ? Through habits of sloth, intemperance and sensuality, drunk- ards make themselves, in a measure, unfit to take proper care of themselves, and then, like carnivorous animals, they prey upon the benevolent community which supports them ; but with this difference, viz., that carnivorous animals generally feed upon animals of other species, while the lazy, slothful and improvident live upon their own species. Some men are especially like the carnivorous animals to this extent, viz., that they consider everything which comes within reach of their claws to be lawful plunder. Others may be likened to children who cannot understand, when they want a certain thing, why they should not have it, although they have not the shadow of a right to its pos- session. But this is not all in regard to the intemperate and 46 WHAT IS LIFE ? criminal classes : they fasten upon the succeeding generation a lot of lazy, diseased, incompetent, and too often vicious descendants; and such live upon the industry of their own species, and become parasites upon the substance of their own race. • From such views of nature and of life, the statement has been confidently made that the Creator cannot be an infinitely wise and benevolent being if He designed that the world of organic life should be as we now find it. The statement is also made, that if animals were created for the purpose of being destroyed to furnish food to other animals, this shows a cruel, instead of a benevolent, design. But this is by no means a logical conclusion. Even if one animal loses its life to give food to another, it by no means necessarily follows that there was no kindness in the creation of the animal thus destroyed ; for we must remember that death, in some way, is a necessity, or the production of life must be stopped, else, as stated above, no sufficient amount of food could be produced by the earth to feed the animals which would be brought into existence. But why could not the Creator have so formed His creatures that they could exist without food ? We may ask a dozen other similar questions ; but, before we can convict the Creator of cruelty in creat- ing animals, we must consider another fact which relates to the balance of existing happiness and unhappiness. If there is much more happiness than unhappiness enjoyed by animals as a whole, was not their creation a benevolent act? It is evident that most animals generally live without fear, and most, if not all, appear to enjoy themselves well, and the short fear that may exist previous to being destroyed cannot be an equivalent or offset to their comparatively long time of enjoyment. ENJOYMENTS AND SUFFERINGS. 47 Take even insects which are devoured by the birds, who knows that in their brief lives they may not enjoy all that their natures are capable of? There must be suitable food for plants, animals, and men, or these cannot continue to exist. Until the objector can show that the animal creation in general does not enjoy more than it suffers, in consequence of its existence, then a balance of benevolence instead of malevolence must be credited to the creating or originating power. But I assume, even in the case of men, who are gifted with the power of reason, and also of reflection upon both their sorrows and their joys, that in general they enjoy more than they suffer. A great proportion of the sufferings of men, however, is caused by unnecessary violations of the laws of nature, though many of these violations may be committed ignorantly. The laws of nature however do not suspend their regular operations to favor one who has ignorantly transgressed them. And the very fact that the laws of nature are invariable in their operations is a blessing; for, if they were not so, how could we with certainty calculate anything in regard to the results of our own or others’ acts ? Even with men natural death is a benevolent reality; for, if no one ever died a natural death, murders would be the rule, since, as above stated, the earth would be so crowded that food enough to feed the human race could not be pro- duced, and hunger would drive to madness, and madness to murder, to get those out of the way who were consuming the food which others needed. But again, in regard to the assertion that an infinitely wise and benevolent power never could have originated the present order of nature, those making these assertions refer especially to the sufferings of men; but even in the case of 48 WHAT IS LIFE ? men, if, as a general rule, they did not enjoy more than they suffer, suicides would be more common. Instead of suicides being one in five hundred, more or less according to the condition of the people, they would be the rule rather than the rare exception. It may be said, in answer, that fear of death or fear of an unknown future existence may so restrain men that many of the unhappy who otherwise might com- mit suicide now refrain from doing so. Here arise two considerations : First, a man must have a conviction that there may be a future life, in which he may be less happy than here, otherwise such a fear would not restrain him. Second, why this fear, if there is not some ground for apprehension on this point? Those who do not believe in a creative power do not believe in a conscious future life; so if the atheist thinks he has more unhappiness than happiness in consequence of his existence, why does he not put an end to his existence? The very fact that he does not argues one of two things : first, he either has some fears in regard to a future existence, or he is conscious that he enjoys more than he suffers in consequence of his existence. But some who claim to be very wise, and to see farther into natural causes than others, assert that blind, unconscious causes could produce all that we see of life; and, further, they seem to think that they have relieved an intelligent designer of a great stigma by attempting to show that an intelligent being could not possibly have formed nature as it is. Such may be wise, but I cannot comprehend such wis- dom. I now call attention to another characteristic of life, viz., its uncertainty. With ordinary machines, like watches, or mill-machinery, we can calculate very nearly how long they will last. Liv- UNCERTAINTY OF LIFE. 49 ing organisms, however, have a recuperative or repairing power in case of injuries (unless they are of a fatal char- acter), while mere mill-machinery has within itself no re- cuperative power; and in this respect the living machine is far above the merely mechanical; yet in the plant bearing the fairest flowers there may be an unseen worm gnawing its vitals. " Thou must decay !” is stamped on all living things. While the presence of life lifts inorganic matter into organic, and thence up through plant into animal life, the departure of life sends this same matter back to its elements ; and thus ever the ceaseless round goes on from death to life and from life to death again. The sunlight acting on the elements causes the grass to grow, and the grass feeds the cattle, producing milk and flesh, and these in turn become food for men and other animals. Then again these higher organisms return to the elements, constantly going from lowest to highest, and back again to lower forms of matter. How like are these changes to the emotions and feelings of living, loving, and intelligent creatures ! Byron wrote, “Man! Thou pendulum between a smile and a tear.” So hearts exuberant and full of joy to-day may be sad or bursting with anguish to-morrow. Nothing on earth is stationary. 50 WHAT IS LIFE ? CHAPTEE 111. WHENCE IS LIFE? Problems which arise in connection with the origin of life and conscious existence are numerous and interesting. For more than two thousand years human intellects have wrestled with these questions, and, as history is said to repeat itself, so the theories advocated and taught by Zeno two thousand two hundred years ago find advocates to-day among highly intelligent men. Inasmuch as some prom- inent writers are now disposed to ridicule and treat as chimerical, ideas, which, for all that they have ever shown to the contrary, may be founded in truth, I will, before proceeding to the direct consideration of questions concerning the origin of life, give a short historical sketch of discussions, and also inquire whether all that is now declared to be scientific has just claims to that proud distinction. Zeno contended that the vital force filled all things, and was ever ready to burst into animated existence whenever favorable conditions existed, and that this vital force con- trolled all things, but that it was an invisible principle, and not a personal God. Thus to worship this was simply an absurdity, which ignorant or illiterate men might indulge in without special harm. So certain moderns contend that everything, even to our conscious existence, springs from eternal and unalterable laws of nature. While many are silent on the question of belief in the existence of a personal Deity, others, like the WHENCE IS LIFE ? 51 Stoics, declare that matter is eternal, and that it has in itself the power of originating life, and thus that the idea of a self- existent and omniscient Creator is a delusion, a mere figment of the imagination. The Stoics contended that life in animals and men is only a part of this everywhere-present vital flame, which simply bursts into a new development in the individual; and, as matter goes its ceaseless round, through inorganic to organic, and from organic back again, so life is simply a phenomenon, an emanation, followed by absorption through death, and thus this vital flame or emanation goes back and forth eternally from death to life and from life to death again. We of the present age consider ourselves wonderfully favored with knowledge of a great number of accurately known facts ; but in this matter of life and its origin, if we throw aside the reasonings of Plato, who taught before the Stoics existed, and who acknowledged a Supreme intelligence or intelligences, and build our knowledge, as Zeno did, simply upon known facts, and pursue our inductive reason- ings only from known facts, we may well come to the con- clusion, from the paucity of such facts to build upon, that in regard to the origin of our existence we can never know the truth with any considerable degree of certainty. Also in many other matters we can never know the absolute truth, and thus well may we ask, as Pilate did, " What is truth ? ” It is very certain that those who are most confident that they hold the truth in its genuineness and purity as the only absolute truth are quite as likely to be in error as those who modestly and sincerely ask, " What is truth ? ” So the decidedly positive writers of the present time, when speculating in regard to life’s origin, are searching in WHAT IS LIFE ? 52 regions where no positive demonstrations exist in our present state of knowledge; and they may well moderate their pre- tension to positive knowledge. They will be wise if they admit that men who are not scientific, but who base their opinions concerning these points on simple statements of what they regard as a direct revelation from God, may really be as philosophical as the positive writers who reject all ideas of revelation, and attempt to reason not from known facts but from premises which have their bases in simple assump- tions. It is quite important that we be able to separate the known from the unknown, and ascertain what is fact, in opposition to what is assumed. Examples are not wanting of men confessedly of high scientific attainments who have adopted theories to account for physical phenomena, and reasoned from premises of which neither they nor any other men ever had experi- mental knowledge. Sometimes such theories have been generally accepted; but subsequent experiments or obser- vations have shown conclusively that these assumed prem- ises could not be true, and not till then have these theories been abandoned. Take, for instance, the kinetic theory of the gases (which may or may not be true), and also that of a luminiferous ether, with which space is (very properly) supposed to be filled; how scientific men have theorized about them, when in neither case have these philosophers ever shown that anything actually demonstrable is known of the supposed facts on which these theories have been built. Who ever saw the ultimate atoms of gases going in straight lines with inconceivable velocities, and either dodg- ing or striking against each other when they happen to meet? Who knows whether these supposed atoms are WHENCE IS LIFE? 53 elastic or non-elastic ? Able scientists disagree here; yet men supporting such theories, while the question whether the atoms are elastic or non-elastic, or, in fact, whether they actually exist under the conditions supposed, is uncertain, have been called scientific. But when some unscientific speculator suggests that facts which no human philosophy has ever explained may possibly be explained by divine revelation, he is (by these philosophers) set down as a victim of credulity, and no philosopher. Of course no man who bases his belief on things demonstrably untrue can be a philosopher. Let it also be fully understood that no in- telligent man has a moral right to put confidence in any theory or doctrine which contradicts well-ascertained and demonstrable facts. Without attempting to decide whether or not this belief in divine revelation is justified by fact from a scientific point of view, I do assert that it may be as philosophical to resort to revelation for an explanation of some things which have never been otherwise explained as it is for a scientist to assume that the theory of the kinetic action of the gases is true, or that an all-pervading ether must exist, simply because he cannot otherwise explain certain phenom- ena, when, in fact, neither has any certain knowledge as to whether his theories are based on facts or not. I say this: that consistency may be considered in argument; and I also ask, how it happens that one speculator who reasons from supposed facts is a philosopher, and another, reasoning from premises also uncertain, is no philosopher? It matters not, so far as real philosophy is concerned, whether these supposed revelations are found in the Koran, or Book of Mormon, or in the Christian or Jewish Scriptures, the believer in either (until the contrary can be shown) 54 WHAT IS LIFE ? has just as good a claim to be considered a philosopher as the scientist who founds his theory of the origin of life on suppositions which he cannot prove to be facts ; e.g. "spontaneous generation.” Thus the men who take their opinions from and build theories of life’s origin on statements made by men eighteen hundred, or even three thousand, years ago, who claimed to get their facts through direct revelation from the original Creator of all things, are as justly entitled to respectful con- sideration as Dr. Hgeckel in his "Natural History of the Creation; ” for he draws his conclusions in many cases as largely from the mysterious and the unknown as do the most credulous supporters of the supernatural or miraculous origin of life. Granted that neither knows for a certainty what the truth is in regard to questions at issue : it may be well to remind these over-positive writers, who ridicule the idea of direct revelation, that they do not hold all the wis- dom or intelligence of this world, and that truths may pos- sibly exist which they do not comprehend, and hence refuse to acknowledge. I am well aware that to certain men this language will be offensive; but no man has a moral right to throw aside supposed revelation from the Supreme Being as worthless without first fairly and intelligently considering whether such supposed revelation is really what it purports to be. It is quite popular with some to scout the idea that the statements of the Bible in regard to the origin of life are of any value, and point to the utter unreliability of the Bible when quoted on any ordinary scientific question. Granted that the Bible is of little value in regard to the common scientific questions (since it is not a scientific book) : that by no means shows that in matters beyond the domain of WHENCE IS LIFE? 55 positive sciences its utterances may not be of great value. Of course there can be no need of any revelation concerning matters of which men can obtain full knowledge by study; for to make a divine revelation in such a case would not only be unnecessary, but it would be a direct encourage- ment to slothful mental habits. Many who reject revelation, and throw it aside as unworthy of notice, have never sufficiently studied its teachings to comprehend what it professes to reveal. What would be thought of a man, who, by learning that, two hundred and fifty years ago, astronomers thought that the sun was not over five millions of miles distant from the earth, should now reject all present calculations of astronomers because they teach that the sun is over ninety millions of miles away ? This would be entirely parallel with the acts of those who throw the idea of revelation aside without proper considera- tion because three hundred years ago, or even in later years, ignorant men have claimed meanings for its teachings which were never intended by its writers. If one receives the Bible as a revelation from God, or the Supreme Ruler of the universe, he should expect to find many statements which the present generation will but imperfectly understand; and many of its teachings will not be thoroughly understood until, through the evolution of events, or by the progress of scientific knowledge, light bursts upon our imperfectly informed students of its mys- teries. No man has a right to throw aside such a book as worth- less until he has first candidly studied it with the purpose of harmonizing its apparent discrepancies, supposing such apparent discrepancies to exist; and no man who. studies 56 WHAT IS LIFE ? such a book while prejudiced against it can be an impartial judge either of its value or worthlessness. Let me not be understood by this to attempt to discourage scientific research. True scientific inquiry is one of the noblest pursuits in which men can engage. What lam now objecting to is the egotism displayed by certain parties claiming to be scientific. Having said this by way of explanation, I will now attempt to develop some ideas connected with the question " Whence is life ? ” A book was written long ago not expressly to teach geography or astronomy, or any other physical science ; but that book does profess to teach us the origin of life and its final destiny, and makes positive assertions about matters w'hich have long puzzled scientific men. Among these assertions are the following : "In the beginning God created the heaven and the earth.” " And God said, Let the waters bring forth abundantly the moving creature that hath life, and fowl that may fly above the earth.” And farther on it says, "So God created man in his own image : in the image of God created he him ; male and female created he them.” And, " God breathed into the nostrils the breath of life: and man became a living soul.” How do these statements agree with the scientific teach- ings? Was there a beginning? Was there an original creation? Was life first developed in the waters? Was man made after the other animals? Was man the last creature into whom was breathed the breath of life ? Does not geology indicate that successive races of animals lived before man existed on the earth ? Does not natural history WHENCE IS LIFE? 57 indicate that the earliest living creatures appeared in the waters ? The Duke of Argyll says, p. 113, "Primeval Man,” " The evidence of geology has always been, that among all the creatures which have in succession been formed to live upon this earth, and to enjoy it, man is the latest born. This great fact is still the fundamental truth in the history of creation. That history, as geology has revealed it, has been a history of successive creations and of successive destruc- tions, old forms of life perishing, and new forms appearing; so that the whole face of nature has been many times •renewed.” Well, then, how about the other two assertions, viz., of an original creation; and, that God was the Creator? Are these as likely to be true as the other two ? The statements rest on the same original evidence, viz., the Book. This book, moreover, states that out of the ground " God formed every beast of the field and fowl of the air.” Can any one show that this is not also true? Certainly in the ground are found all the materials which enter into the bodily composition of men, beasts of the field, and the fowls of the air; and who can show that they were not thus formed as above stated, even if the popular development theories prove to be true ? or that it took millions of years to develop a perfect man from the original germs ? This book conveys the idea that God was the author and originator of all life. Do we know, or does any one know, to the contrary? I do not introduce this inquiry to contradict anything which science has demonstrated; but when the Book states truly all facts concerning which we have positive scientific testimony on this subject, is it not reasonable to presume 58 WHAT IS LIFE ? that its other statements, which science cannot prove to be either true or untrue, may also be true? What right, in the absence of contrary information, has any one to assert that they are not true ? But some do not assent to this manner of statement, and, if it can be shown that this statement is not founded on actual fact, then it must be acknowledged that the origin of life is involved in obscurity ; for when we leave this con- clusion, and try to find this origin through scientific research, the most learned men disagree, and, if they speak freely, they admit that they have only suppositions for foundations of many of their hypotheses. My inquiries are now limited to the life which is on the earth. I do not attempt to inquire into the character or origin of life on the planets or stars (from want of proper information on this point), though the discussion of planet life might be as sensible and profitable as many of the discussions concerning evidence in support of certain modern scientific hypotheses. Yet searching inquiry into the foundation principles of scientific truth (if of a practical character) is one of the most noble occupations in which an intelligent being can be engaged. Some, however, assert that all natural bodies are living, and that the distinction generally thought to exist between the living and the non-living does not really exist. But it seems to me that there is a distinct line between the living and the dead which should be evident to every one whose mind has not become befogged with speculative ideas. I propose to examine some of these philosophic speculations in relation to the origin of life, and see if we can deduce any useful or profitable conclusions concerning the same; and also bring to view as much real truth as may be gleaned from my means of investigation. WHENCE IS LIFE? 59 The most important question connected with man’s origin and destiny is one which science cannot demonstrate, viz., "If a man die shall he live again ? ” The question whether man is to continue in a state of conscious existence after death is much more important than how he happened to be in existence, or whence his life came. As far as science has been able positively to teach, both questions are involved in mystery ; and they are not only intimately connected, but that pertaining to a future existence (if it can be shown that a future existence is probable) has a momentous bearing upon man’s highest welfare. But in writing thus it is proper to remember that some do not believe in the immortality of the soul, or in its spiritual existence, and hence such must be approached from another direction, and must be reasoned with on other grounds, if we are to have satisfactory arguments with them. Materialistic doctrines are preached, printed, and urged with vigor, and are read far and wide, and it is unwise for those who claim to be guided by reason to throw such thoughts and supposed dis- coveries aside without due consideration. But that my readers who feel so great delight in the con- templation of a blissful future existence may not be disturbed by the course of this discussion, it is proper to remark at this stage that the questions which arise in discussions between materialism and spiritualism run into each other to a greater extent than the decided advocates of either theory seem to imagine. Suppose, for instance, that a materialist assumes that souls of men (if they have any) are material: what then ? Does he know that it is so, or does any one know to the con- trary? We can easily Imagine that a material essence may exist and yet be a thousand times more tenuous than the 60 WHAT IS LIFE ? most subtle gas we know of; it may still be material and yet of such extreme tenuity that no human intelligence can tell whether it is material or immaterial. Thus the dis- cussions concerning the question whether the spirit of man is material or immaterial are not of so essential importance as many suppose, and the decision either way (which of course no man can positively give) cannot touch the question of all questions, the one of supreme importance, viz., that pertaining to the continued conscious existence of moral and intelligent beings after death; though I am aware that some of the best men fear that the admission of a doubt upon this immaterial question may be attended with disastrous consequences to cherished beliefs and brightest hopes. I do not share these fears ; for, if assured of a con- tinued conscious and happy existence, it is not of much consequence whether this existence is continued in material or immaterial garments. But to return to our question: "Whence is life?” We may properly inquire, where do we discover the first appearance of life ? It is generally conceded that the basis of all physical life is " protoplasm,” or, as Dr. Beale more properly calls it, "bioplasm.” I shall, however, use the term protoplasm, because it is so generally used by a large class of writers on the point under consideration. Protoplasm consists of minute particles of organic matter. These particles, or molecules, enter into the composition of all living plants and animals, and now two distinct theories of the origin of life confront us. As stated in a previous chapter, for ages past physiolo- gists of two different schools have opposed each other on the question whether life is a cause or aA effect. One school of physiologists claims that life is simply the result of the WHENCE IS LIFE? 61 organization of matter, and hence life cannot exist separate from matter. The other school asserts that life is not the result of organization, but is the cause of the organization of matter into living beings. These two theories are as wide apart as the poles, and the whole question turns upon one actual fact, and this fact fixes, or determines, the position which life holds in connec- tion with all animated existences upon earth. Briefly stated, it is whether life is the cause which precedes and regulates the formation of living organisms, or whether life follows and is added to the organization as a result. Is the principle of life the cause which operates to pro- duce or evolve living beings ? Does it impel the particles of protoplasm or bioplasm to come together, and become distributed throughout the organism, so that bones and muscles grow and build themselves up into visible corporeal frameworks ? We must bear in mind that one distinguishing trait of liv- ing matter is motion. Many confound the action of living matter with that of crystallization, and represent their actions to be similar. But the action of living matter differs greatly from that of crystallization, from the fact that living matter moves by internal power, while crystallization never does this. Organic matter, or bioplasm, goes by its own motion to inorganic matter, and takes it up and as- similates it. Inorganic matter has no power itself to move, though it may be attracted by another body. Doubtless life exists in granules of protoplasm or bioplasm long before their molecules become large enough to be seen by or with the most powerful microscopes. And a motion similar to that in the smallest particles which we can discover doubtless exists before we can by 62 WHAT IS LIFE ? any means discover any motion. Can we then conclude that the corporeal system is brought together by chemical or other causes, and life simply a concomitant, resulting from the organization, brought in by natural causes, and thus worked into the wonderful living mechanisms found in various animals, and in the highest types of humanity? In regard to the commencement of human physical exist- ence and the acts which spring from inherited tendencies, Dr. Maudsley says : "No power of microscope or chemistry» no power which science can make use of will enable us to distinguish the human ovum from the ovum of a quadruped; yet it is certain that the former has inherited in its nature something whereby it develops under suitable conditions into the form of a man, and that the latter has in like manner inherited something whereby, under suitable conditions, it develops into a quadruped.” (p. 21.) The nature of the man as well as of the beast is contained in the ovum, even when it is less than one hundredth of an inch in diameter, when no microscope can enable us to tell the beast from the human, and yet, when but little enlarged from this minute state, the living creature is already divided into two sides, which resemble two leaves, and molecular actions are then going on as surely as in the mature organism. When more enlarged, minute specks representing beginnings of arms and legs appear; but even then it is impossible to tell whether it is a biped or a quadruped, although the whole peculiar nature is already there ; so true is it now, as in the days of Adam, that " every living thing brings forth after its kind.” The nature being in the ovum, if we are to look for the starting-point wTe must look for germs of life antecedent to anything which wTe can detect with the micro- scope, even to the first atom of living matter, which attracts WHENCE IS LIFE? 63 to itself another congenial atom of like matter and then com- mences to build the physical framework of the living animal. The ultimate principle of life must be then in these living particles. But this does not explain when or where the personal life of separate individuals commences. To show that living action can be seen in minute specks of bioplasm, I quote (second hand) from Dr. Beale. " One characteristic of every kind of living matter is spontaneous movement. This, unlike any movement of non-living matter yet discovered, occurs in all directions, and seems to depend on changes in the matter itself rather than on im- pulses from without. I have been able to watch the move- ments of small amoeba under a magnifying power of five thousand diameters. Several of these were less than a hundred thousandth part of an inch in diameter, and yet were in a state of most active movement. The alterations in form were very rapid. They might be described as minute portions of very transparent material, exhibiting the most active movement in various directions in every part, and capable of absorbing nutrient materials. A portion of what was one moment at the lowest point would pass in an instant to the highest. One part seemed, as it were, to pass through the other parts, while the whole mass moved, now in one, now in another direction. What movements in lifeless matter can be compared with these ? ” Doubtless the living principle commences to build the ovum when it is as minute as these specks of living matter; and this is- as really life, in one of its phases, as the life in mature individuals. But the life of a separate individual as a real personality commences when the seed, or male cell, and egg, or female cell, coalesce and become one; and this, in most cases, doubtless occurs before these combined cells 64 WHAT IS LIFE? are one hundredth of an inch in diameter. Then these combined cells commence to throw off other cells of two different kinds, and one kind goes to build up the outside framework of bones, muscles, limbs, skin, etc., and the other kind goes to form our inside organs, as heart, lungs, stomach, bowels, etc. ; and thus the framework goes on till the physical form is complete. Not only every beast, but every plant, brings forth after its kind, and the nature of the plant is contained in the, seed. Why should trees planted side by side, with their roots running in like soil, secrete juices so different from each other? Why should the maple secrete sugar, while by its side the deadly nightshade secretes poison? What power short of infinite intelligence could endow these trees with such wondrous powers of discrimination that none ever make a mistake, and secrete any nourishment which can change their distinctive characters? Water is supposed to be the vehicle which carries nourish- ment over the tree or plant, and leaves it where it belongs. Water holds in solution various kinds of protoplasm, and carries them over the living tree to its smallest twig1 and the O O most tiny bud. Afterwards the water is evaporated, and passes into the air pure water; but it leaves in the tree some of the solid matter which it previously held in solution. A large part of the living tree is water. So of our own bodies, over 70 per cent, is water, and about the same pro- portion of our blood is water. Without water there can be no living, active, physical existence. Water in our blood is believed to carry over our bodies the nourishment needed to sustain us, placing particles which make our bones and mus- cles and brains just where they belong. We have said that living actions are in the ovum when it WHENCE IS LIFE? 65 is only a minute globule, and that life has distinguishing traits in the little embryo, though we cannot tell what kind of animal it is ; but even at the very first existence the life principle is exercising its preserving influences ; for let life be destroyed, and then what? The molecular action which is peculiar to life ceases instantly, and the very first chemi- cal or molecular action that succeeds is that peculiar to dead bodies, and in the direction of decomposition. No chemical differences just before death and just after can be detected in the mature animal; but the ceasing of the living kind of molecular action is instantaneous at death (or really is death), though digestion or chemical action often continues in the stomach after death. But digestion is not a vital action. Now what is the power which causes an instantaneous stoppage of living action? What is that which leaves the body that instantaneously produces a difference so radical? Is this change the result of disorganization? Or does the departure of the living principle cause this change? If organization is the cause of life, and life merely the result, would not the character of the organization instantly change at death? But can we detect any difference in the physical organization just before and just after death? So far as can be seen with the most powerful microscopes, the very com- mencement or beginning of every animal organism is accom- panied by life. If organization is the cause of life, then life is its effect. As the cause must always precede the effect, so if organization is the cause of life, then organization must pre- cede life. But, if this does so precede, why is it that no man with the most powerful microscope ever saw animal or vege- table organization beginning before life is in it? Are they coexistent ? It is quite a different thing to suppose that life’s 66 WHAT IS LIFE ? principle is the cause of organization ; for the principle of life, if it has a real existence, is invisible, and hence could not be expected to be seen doing this work of organization. Its work can only be seen in its effects. Rapid vital action can be seen in the most minute amoeba; but no such action was ever seen in inorganic matter. If departure of life causes a change towards decomposition, why should not the entering in of life be the immediate cause of composition or organization? It is true that those who understand that the original creation of man, as described in Gen. 2 : 7, is to be taken as a literal statement of fact will find that man was made out of the dust of the earth, and his physical organization com- pleted before God breathed into him the breath of life. In this one case, as stated, organization preceded life. But there is little fear that those who contend that organization preceded life will cite the case of the original creation of man as an authority to which they would appeal in regard to the present manner of the production of life. Prof. James Orton, in his work on comparative zoology, speaking of the lowest organisms, p. 30, says: "It has been supposed that muscular and nervous matter is diffused in a molecular form ; but all we can say is, that the highest power of the microscope reveals no organized structure whatever, i.e., there are no parts set apart for a particular purpose, but a fragment is as good as the whole to perform all the function of life. The animal series, therefore, begins with forms that feel without nerves, move without muscles, and digest without a stomach; in other words, life is the cause of organization, and not the result of it. Animals do not live because they are organized, but are organized because they are alive.” Herbert Spencer says : " Does structure originate function, WHENCE IS LIFE? 67 or does function originate structure ? is a question about which there has been disagreement. Using the word func- tion in its widest signification, as the totality of all vital actions, the question amounts to this: Does life produce organization, or does organization produce life ? ” " To answer this question is not easy, since we habitually find the two so associated that neither seems possible without the other; and they appear uniformly to increase and decrease together.” . . . "There is, however, one fact implying that function must be regarded as taking precedence of structure. Of the lowest rhizopods, which present no distinctions of parts, and nevertheless feed, and grow, and move about, Prof. Huxley has remarked that they exhibit life without organization.” (" Biology,” pp. 153 and 154, vol. 1.) " It may be argued that, on the hypothesis of evolution, life necessarily comes before organization. On this hypoth- esis, organic matter in a state of homogeneous aggregation must precede organic matter in a state of heterogeneous aggregation. But since the passing from a structureless state to a structured state is itself a vital process, it follows that vital activity must have existed while there was yet no structure; structure could not else arise. That function takes precedence of structure seems also implied in the defi- nition of life. If life consists of inner actions so adjusted as to balance outer actions, —if the actions are the substance of life, while the adjustment of them constitutes its form, then may we not say that the actions to be formed must come before that which forms them? that the continuous change which is the basis of function must come before the structure which brings function into shape? "Or, again, since, throughout all phases of life up to the 68 WHAT IS LIFE ? highest, every advance is the effecting of some better adjust- ment of inner to outer actions, and since the accompanying new complexity of structure is simply a means of making possible this better adjustment, it follows that function is from beginning to end the determining cause of structure.” ("Principles of Biology,” vol. 1, p. 167.) It seems to me that these extracts ought to carry convic- tion ; but I will quote once more, and this time from the Duke of Argyll, He says : "The deeper we go into science the more certain it becomes that all the realities of nature are in the region of the invisible ; so that the saying is literally and not merely figuratively true, that the things which are seen are tem- poral, and it is only the things which are not seen that are eternal. For example, we never see the phenomena of life dissociated from organization : yet the profoundest physiolo- gists have come to the conclusion that organization is not the cause of life, but, on the contrary, that life is the cause of organization, life being something a force of some kind, by whatever name we may call it which precedes organi- zation, and fashions it, and builds it up. This is the conclu- sion come to by the great anatomist Hunter, and it is the conclusion indorsed in our own day by such men as Dr. Carpenter and Prof. Huxley, men neither of whom have exhibited in their philosophy any undue bias towards either theological or metaphysical explanations.” ("Feign of Law,” p. 118.) Many are now looking for the beginning of life among very minute animals which are as little as possible removed from inorganic matter, and if they could only once see in- organic matter changing into organic, and observe in what this change consists, and how it is accomplished, then a WHENCE IS LIFE? 69 starting-point might be found. Some are still sanguine that this process will be discovered. I do not belong to this hopeful class. It seems to me to be quite as profitable to scrutinize with more care the origin of animals higher in the scale of life. The inductive method can just as well be applied here, and apparently with quite as much profit. But most of this kind of investigation seems to have fallen into the hands of those who are inclined to believe that all the forces which make these wondrous changes inhere in matter itself. Many of them are careful not to express their opinions, as to how or by whom this power became fixed in nature, though some are ready enough to state that, in their opinion, this power was never placed in nature, but that it has existed there eternally. Since writing this last paragraph I see that Prof. Birks takes a similar view as to the proper place to begin investi- gations, when speaking of individuality (p. 279, " Modern Physical Fatalism”), as follows : " The objections which have been raised to the essential individuality of life are drawn entirely from its lowest and most obscure forms, or microscopic animalcules, invisible to the naked eye. These are exceedingly minute in size, their number immense, their modes of reproduction very similar, and the laws of their reproduction very difficult to trace. But it surely reverses the first lesson of genuine philosophy to have recourse to the most obscure corner of a wide and important science for its definitions. This is to interpret day by night, and clear sunshine by mist or darkness. In all the higher forms of life, with which mankind has been familiar for long ages, the marks of individuality are clear, decisive, and irresistible.” 70 WHAT IS LIFE? It may be asked, What good can come from inquiry into such hidden mysteries ? In turn, I ask, What harm can come from it ? The truth can stand the most searching inquiry; and any theory which cannot abide the most searching inves- tigation had better be surrendered. I have no fears for the safety of eternal truth. Materialists contend that there is no such thing as " vital force ” separate from matter. Monists assert that there can be only one original force in the universe. Dr. Haeckel, the greatest living exponent of monism, or the unity of force and matter, writes (p. 456, vol. 2, "Evo- lution of Man”) : "Goethe says, matter can never exist and act without spirit, neither can spirit without matter. The real materialistic philosophy asserts that the vital phe- nomena of motion, like all other phenomena of motion, are effects or products of matter.” That is, that all active forces in living animals are the product of matter. " The other opposite extreme, spiritualistic philosophy, as- serts, on the contrary, that matter is the product of a motive force, and that all material forms are produced by free forces entirely independent of the matter itself. Thus, ac- cording to the materialistic conception of the universe, matter, or substance, precedes motion, or active force. Ac- cording to the spiritualistic conception of the universe, on the contrary, active force, or motion, precedes matter.” That is, the spiritualistic view is that there must have been an active spiritual force to organize matter into worlds as well as into living animals, or else they could not have existed. Dr. I Deckel adds, in regard to both the materialistic and spiritualistic views, as follows : " Both views are dualistic, and we hold them both to be equally false. A contrast to WHENCE IS LIFE? 71 both views is presented in the monistic philosophy, which cun as little believe in force without matter as in matter without force.” Also, " The spirit and mind of man are but forces which are inseparably connected with the material substance of our bodies.” Again (on p. 457) : " The magnet attracting iron filings, powder exploding, steam driving the locomotive, are active inorganic substances. They work by active force, just as does the sensitive mimosa when it folds its leaves at a touch, as does the amphioxus when it buries itself in the sand, as does man when he thinks.” " Only in these latter cases the combination of the differ- ent forces appearing as phenomena of motion is much more complex and much less easily recognized than in the former cases.” Although Haeckel does not say in so many words that the active inorganic and organic forces are just the same in kind, or that the living forces in men are of the same quality as the explosive qualities in gunpowder, yet, by all fair rules of reasoning, he leaves us to infer that all the dif- ference he believes to be in these forces is in their com- plexity, and not in their kind; that is, they appear to be different merely because one is more pronounced. But in the quality of the acts there is no difference : both proceed from the same forces in nature; and these are one and in- divisible in their real nature. On p. 17, vol. 1, Dr. Haeckel says of the doctrine of evolution, "ithas enabled us to substitute everywhere unconscious causes acting from necessity for conscious purposive causes.” He adds that the monistic philosophy " must ultimately prevail through philosophy.” It is easy to make the statement that there is no need of 72 WHAT IS LIFE? any spiritual being to organize matter into worlds, or to put life into living animals, if we are able to " substitute unconscious causes everywhere for the conscious causes,” which people have thought must have existed, and thus dispense with the necessity of any intelligent planning and organizing of the universe, because the causes of all these things have acted from necessity. But how does this account for the origin of things? How could this necessity of which he speaks exist unless some power behind or antecedent to this necessity ordered that things should of necessity take place? To attempt to account for the origin of things in this way is simply to plunge into greater darkness ; for it accounts for nothing till he informs us how this necessity came to exist. Prof. Birks says : " The attempt to get rid of purpose or design, so as to refer all the acts of living creatures to mechanical laws and processes alone, is revolting to the common-sense of mankind. Under learned phrases it strives vainly to conceal an unusual amount of self-con- tradiction and logical absurdity. The hive bee aims at constructing its cell, and then storing it with honey; the bird uses much skill in building its nest and preparing it for the • future process of incubation. The mason does not seem more truly to follow the design of the architect than insects of various kinds satisfy the outlines of some plan or type in forming their habitations, which has been appointed to. them from the beginning.” Now if nature alone (without any intelligence control- ling the laws of nature) teaches the bees to build their combs, and the birds to build their nests, we may be un- reasonable to require an answer as to how this supposed necessity happened to exist. But, in regard to the sup- WHENCE IS LIFE? 73 posed innate powers of nature, or the power of originating life, which monists contend inheres in matter, it may be re- marked that if the Deity, in pursuance of his plan, chose to endow matter with life-originating powers, without doubt he had the power to do so. But the simple question now to be answered is, has he done so? All persons who believe that the body and the soul are separate and different qualities or entities are called dualists; and those who believe that the soul may exist prior to, or separate from, or independent of the physical organization are called spiritualists. But these last are also dualists. Under this classification all who believe the teachings of Socrates and Plato are spiritualists, though of necessity they are dualists. We have stated our belief that " Life is the cause of organization ; ” and thus you will see that we must also believe in a principle of life existing antecedent to any out- ward manifestations of life either in men or animals, and in fact ■ that this indispensable force underlies all physical life. On the other hand, materialists and monists deny that there is any living or life-giving force separate from or dis- connected with matter; and the reason they can maintain what seems fallacious is because we cannot see any mani- festations of force or being unless that force is connected with or acts on matter. Even an emotion of the soul, though doubtless immaterial, cannot be perceived by us except through the action of the brain, a physical organ, and thus it is impossible to demonstrate the existence of soul, mind, or feelings separate from our bodies ; and this is why monists have the courage to challenge men to confute their statements. 74 WHAT IS LIFE? It has been asserted that since the brain is the organ of the mind, mind cannot exist except in connection with the brain. While conceding that man can see no manifestations of mind except through its physical organ, the brain, no one is justified in asserting that mind may not precede the very organization of the brain, and have existed prior to and hence separate from it. For anything that man knows to the contrary preexisting mind not perceptible by man may have been the cause which gave to the brain its particular shape, and then took the brain as its organ of communication with other intelligent creatures. For all that we know mind may be coexistent with life, and doubtless was in the beginning, if there ever was a beginning. So it may be coexistent with life in the ovum, at the very commencement, when the first combined cells begin to throw off other cells, and thus commence the development of the embryo. When men assert that soul cannot exist separate from matter they state what they do not know; and thus we are again thrown back upon first principles, and obliged to reason not from what we can see with our eyes but upon general manifestations of existence as displayed all around us. Much has been written upon this subject. I will now give some extracts from leading thinkers, that we may see the grounds of difference between them. There are different grades of each of the classes enumerated above, but when I refer to either of them it is as scientists, not as religion- ists. Thus, among spiritual scientists there are two essen- tially different classes. Some are of the Berkeley stamp, who do not believe in the existence of matter, and think " All being may be reduced to mind, or ideas in a mind.” WHENCE IS LIFE? 75 J. G. Fichte says : "One of the two, spirit or matter, we must let drop : the actually true and real being is spiritual; and there is no other being.” Czolbe says (See "Voc. Phil. Sci.,” by Krauth, p. 908) : " The power of organisms cannot be explained by the plan- less and formless chemical and physical activities. Nothing is left us but to throw ourselves into the arms of mysti- cism by accepting a supersensuous vital force, or in acknowl- edging the eternity of matter to acknowledge also the eternity of form.” On the other hand, Moleschott " opposes the doctrine of vital force, as he defines it,—a force without substratum, and yet endowed with personal quality.” Schopenhauer says (Krauth, p. 909): "The polemic against the supposition of a vital force is stupid.” " The denial of the vital force is absurd. Were there not a peculiar force of nature, to which it is as essential to act in conformity with aim as it is essential to gravity to draw bodies towards each other; did it not move, guide, regulate the whole complicated mechanism of organism, life would be an illusion, an imposition, and we should have a mere automaton, a plaything of mechanical, physical, and chemical forces. It is not disputed that physical and chem- ical forces are at work in organisms, but that which holds them together and guides them, so that an organism con- forms to its purpose, comes to being and subsists, that is vital force.” " The vital force certainly uses and brings into its employ the forces of inorganic nature, but by no means consists of them ; just as little as a blacksmith consists of his hammer and anvil.” " Hence, not the very simplest plant life can be explained by those forces, as, for example, by capillary attraction, or by endosmosis, to say nothing of animal life,” 76 WHAT IS LIFE? " A fundamental distinction between the vital force and all other forces of nature has been in the fact that when the vital force once forsakes a body it never takes it into pos- session again.” How radically different this from the action of natural, chemical, and mechanical forces, as electricity, magnetism, etc. ! The same body may be magnetized and demagnetized, or electrified and relieved of its electricity, many times, with- out change in the appearance of the body. So simple chemical elements may be compounded, decomposed, and recompounded, almost to any extent. Why? Because such action is mechanical instead of vital. It seems to me that nearly every one who comes with un- prejudiced mind to a careful study of the vital forces or prin- ciple must reach the conclusion that something besides mere mechanical and chemical forces is required to originate, build up, and preserve living, thinking, and reasonable men. This question concerning an original living force is in- timately connected with the origin of our conscious existence, and with the question, how can mental and spiritual exist- ences be connected with physical systems ? Here is a region in which reason and philosophy must take the place of physical demonstrations ; for, notwithstanding all claims to the contrary, there are no physical demonstrations on this point. The Duke of Argyll well says ("Reign of Law,”p. 271) : " Science should be allowed without suspicion or remonstrance to pursue her proper object, which is to detect, if she can, what the method of this work has been. There is no point short of the last and the highest at which science can be satisfied. Her curiosity is insatiable. It is a curiosity rep- resenting man’s desire for knowledge. But that desire ex- WHENCE IS LIFE? 77 tends into regions where the means of investigation cease and in which the processes of verification are of no avail. Above and behind every detected method in nature there lies the same ultimate question as before, what is it by which this is done? It is the great mystery of our being that we have powers impelling us to ask such questions on the his- tory of creation, when we have no powers enabling us to solve them.” "The faculties of both reason and imagination fall back with a sense of impotence upon some favorite phrase, some form of words built up out of the materials of anal- ogy, and out of the experience of a mind, which, being finite, is not creative. We beat against the bars in vain. The only real rest is in the confession of ignorance, and the con- fession, too, that all ultimate physical truth is beyond the reach of science.” This again brings us face to face with the question, " Whence is life? ” The Duke further says (p. 273) : Crea- tion by law, evolution by law, development by law, or, as including all those kindred ideas, the reign of law, is nothing but the reign of creative force directed by creative knowledge, worked under the control of creative power, and in fulfilment of creative purpose.” And after all our in- quiries concerning the origin of life, and under what law it came into existence, the reflecting mind cannot help going further, and asking, " whither ? ” With those who contend that life, soul, and matter are inseparable, we cannot hold much argument on the direct question of the origin of life ; for if life and intelligence are of necessity coupled with matter, or sprung from matter, there is nothing to argue about. But until monists and materialists can bring something beyond mere assertion, I shall proceed on the theory that a vital principle, or living 78 WHAT IS LIFE? force, underlies all physical life, and that all living beings now on the earth received their life from antecedent life just as certainly as they have received their physical systems from beings with physical organs. And further, that all life now on the earth had its origin in the first self-existent being. But why assume the existence of a self-existent being? How can we comprehend this ? We comprehend this just as well as men do the assertion that matter must have existed eternally. There is quite as direct evidence of a self-existent, Almighty intelligence, as there is that matter, even in its simple elements, is eternal. If matter is eternal, it seems evident that its eternal qualities must inhere in its simple elements, or in cosmic vapor, and not in compound bodies, as matter now generally exists. However, before proceeding further in the direct line of argument, let us consider some preliminaiy speculations and facts concerning the first origin of things. Every event which now occurs has some antecedent, and every effect has a cause ; but, if the same laws of cause and effect always existed, how could we get to the first cause, or a cause which was not caused? Is there an infinitely-extended chain of causes without a beginning? We have two alternatives, viz., either to suppose that during past time or eternity the same relations of cause and effect which now act by or through invariable antecedents and sequence did not then exist as they do now, and hence that parts of what we now recognize as the laws of nature have not been eternally in existence, or we may assume that all natural laws have eter- nally existed. But if we assume that something is self-existent, or always existed, what is that something? Mind certainly exists, and matter certainly appears to exist. Did mind WHENCE IS LIFE? 79 precede the existence of matter? Or have both mind and matter existed eternally? Or has matter alone existed from all eternity, while mind has not so existed ? And has mind been evolved from matter, as some suppose? If so, by what process was this evolution accomplished ? Or, on the other hand, did mind, through its act or acts, cause matter to be spoken into existence? Our minds are so constituted that it is easier to conceive that both mind and matter existed eter- nally than to suppose that something material was created out of nothing. But we are necessarily driven to one of three conclusions : first, either the supposed existence of matter is a delusion; or, secondly, something has been created out of nothing ; or, thirdly, that matter existed eternally. Can we believe that mind is the product of matter? How can we account for its existence ? Can we conceive it as self- existent ? If only one principle or entity can be self-exist- ent, is that entity mind or matter, material or immaterial? The same difficulties arise in regard to the origin of life as in regard to the origin of intelligence and of conscious existence; and the question naturally arises, How did life first happen to exist? Can it be that life, by its very nature, was self-existent? Or was there an original self-existent being, who, from his very nature, is the father of all suc- ceeding life, or, figuratively speaking, the fountain from which all succeeding streams of life have flowed ? Speculate as we may, there must be solid truth which would answer all these questions if we are able to discover it. But the difficulty which stares us in the face is the question, How can we discover the foundation truths in regard to these questions ? Two thoughts readily arise: First, we may never be able to know these facts ; and, second, it may not be necessary that we should ever know. Another 80 WHAT IS LIFE? question is this : if it is beyond the capacity of the human mind to discover all the facts pertaining to the origin of life through investigation and study, would a self-existent intel- ligence be likely to reveal to men the foundation facts in regard to life’s origin ? Is it really necessary that man should know this? If it is, does it not seem likely that a being who nearly all thoughtful men believe existed eternally might reveal the most important facts concerning this origin to man? Men claiming to be inspired and instructed by a self-existent intelligence have written what they assert to be a divine revelation in regard to life’s origin. Is it im- probable that these men have had revealed to them the real truth ? Is it reasonable to believe that all life has been re- ceived from a self-existent life ? Can we think of a more probable origin, or name one easier to be understood? Surely, if it is necessary for us to know the fundamental truths concerning this question, should we not reasonably expect that this knowledge would be revealed to us ? It is easier to ask than to answer these questions ; but our subject leads us to consider these questions and inquire how near we may approximate to the proper answers. Following out these lines of thought, we may assume that everything compounded from simple substances must have been in simple elements before it could be compounded; and if so, the compound body must have come into existence as such later than these simple elements, and hence, from its very nature (if the above supposition is correct), the com- pound cannot be eternal.1 1 While discussing questions concerning the origin of things, it is well to re- member that we do not for a certainty know what either spirit or matter is; but we must use these words according to their commonly accepted meanings. WHENCE IS LIFE? Take, for instance, one of the most common elements in nature, water: is it not philosophic to suppose that oxygen and hydrogen existed in immense quantities within the region occupied by the solar system before these gases united in the proportion of eight to one in weight and two to one in volume to form Avater, under the laws of nature? Then what power first set the chemical, attractive, or other forces at work to make the compound? Was it not the same invisible and eternal power which, under natural laws, said, let intelligence and brains be united? As the oxygen might have existed separate from and independent of the hydrogen, so mind, or intelligence, might have existed prior to the existence of any physical organs. Who knoAvs to the contrary ? We must keep in mind that life and intelligence are essentially different things ; and, although avc are accustomed to group them together, avc do not know how intelligence can exist separate from some kind of life. We suppose that life may exist without intelligence ; but we believe that in- telligence cannot exist without accompanying life. Yet in- telligence may linger in a man even Avhen we can detect no signs of mind remaining. For instance, a pressure upon the brain may destroy all appearance of intelligence, and the removal of that pressure restore the power of action to the brain, and with it the power of memory and reason. This could not have been the case if the intelligence did not really exist somewhere (though to our senses in an im- perceptible degree), while the pressure continued upon the brain. But life exists in a tree without any accompanying mani- festations of intelligence which we can see ; and yet wre do not know that trees may not have dim outlines of intelligence ; 82 WHAT IS LIFE? but we take it for granted that they have no intelligence. But we have no tangible evidence that any intelligence now exists upon the earth without physical life, as we can per- ceive no intelligence except in living animals. We infer then that some kind of life must be coexistent with all intelligent action, as intelligence can be manifested only by living beings. But if, on the other hand, the visible mani- festations of being in the world imply intelligent organiza- tion, then some intelligent power or force must have been coexistent with, if not existent prior to, the first physical organization. It seems evident that the compound bodies which we now see, cannot, in the very nature of things, have been eternally in existence as such. Well, then, did these simple elements, or cosmic vapors, rush blindty and by chance into the orderly combinations and exquisitely beautiful arrangements of worlds and systems of worlds as they are now, with all their surprising harmonies, and that without intelligent guidance ? If we can show that at the outset there must have been intelligent guidance, of course intelligence must have been coexistent with the first atom, or at least must have existed before the first ultimate atoms began to be attracted together, or rushed together, as believers in a chance world express it. If our conceptions concerning the necessary connection of life with intelligence are correct, then a life not connected with a physical organization must have existed in the very beginning (if there ever was a beginning), or at least before the first original atoms of matter began to be attracted together, life being coexistent with the first intelligence. It then appears that life and intelligence would naturally be coexistent, and that each existed antecedent to the very WHENCE IS LIFE? 83 first movements of matter even if they did not precede the very existence of matter. And if life was coexistent with the simple elements of matter, and these elements have existed eternally, it follows that life, or a living principle, must also have existed eternally. But it is as easy for me to conceive that intelligence and some kind of life may have existed prior to the primary elements of matter as to believe that both life and matter are eternal. Certain men tell us that the human mind cannot conceive of such a thing as self-existent life or intelligence; but I beg to dissent from that statement, which is simply an assumption, and also to say that, if parties making that statement cannot conceive of self-existent intelligence, it by no means follows that others may not be able to conceive of something pertaining to it, and they have no right to assert that others cannot justly reason about it. The king of Siam could not understand how water, through the action of cold, could become solid, for he had never seen ice,—and hence he rejected the statement that water could be made solid as absolutely absurd, because inconceivable to him. I do not claim that the human mind can fully comprehend the idea of self-existence, or that it can comprehend the idea of the creation of something out of nothing, supposing such a thing ever could have happened ; but we know that some- thing does exist, and the question is how that something came to exist, provided it did not exist eternally. The creation of something out of nothing seems unthink- O O able; and yet the fact of its being unthinkable by no means proves that it could not have been done, although I cannot comprehend any process through which it could have been done. 84 WHAT IS LIFE? The mind is a mysterious thing, and no one has any right to assume that others may not understand or comprehend certain things because he cannot comprehend them. So with infinity and space. I have no doubt that some men have a kind of dim comprehension of what has generally been considered incomprehensible. lam not alone in this opinion, for such thinkers as R. W. Emerson and Theodore Parker have plainly intimated as much on this point; and I do not think they can be classed with those who believe too readily in the supernatural, or that they were unduly credu- lous. I intend to examine the theory of spontaneous generation, but can now only glance at it, and the examination must be postponed for subsequent treatment. Dr. Eheckel believes that men and animals have descended from minute living organisms called monera, and that these original organisms came from matter by "spontaneous gen- eration” in the "Laurentian period.” This is the way he accounts for the first origin of life upon the earth, rather than admit that it received its existence from a self-existent creator; but I cannot see how it is easier, or indeed how it is as easy, to imagine that matter, without preexisting intel- ligence, could originate intelligence through chemical action, as it is to conceive that life and intelligence were originally self-existent. He simply substitutes matter, as the originat- ing power, for living intelligence. Hence his theory of " spontaneous generation ” does not help us one particle towards the solution of the question, whence is life? All the evidence in favor of his theory is entirely assumed, for no man ever saw "spontaneous generation,” or anything like it. Besides, the investigations of M. Pasteur, the distin- guished French chemist and physiologist, during the past WHENCE IS LIFE? 85 fifteen years, aided by the able scientist Prof. Tyndall, and also by the exhaustive experiments of other competent chem- ists, have apparently exploded the evidence which certain chemists and naturalists had previously adduced in favor of the theory of "spontaneous generation,” and proved that facts which they supposed indicated spontaneous generation did not indicate its existence, and that neither in the present nor past history of the world has positive evidence been pro- duced which shows that such a thing as spontaneous genera- tion ever existed. The germ theory, which shows the fallacy of spontaneous generation theories, of itself does not state how, in the first place, these life-germs came to have existence; but experi- ments tend to show that no living creatures now come into existence except through life-germs. As such a thing as spontaneous generation cannot be shown to exist now, is there any good reason to think it ever existed on the earth? The forces of nature (according to all we know, or as far as we can produce any evidence) are not now less than formerly. The doctrine of the conservation of energy, gen- erally accepted by our scientific friends, forbids the idea that any particle of force is ever lost. Every cause now must have its full effect, and that effect must be properly related to and equal to its cause, and vice versa. And until some one can show that in some past time present laws of cause and effect did not exist we must be- lieve that they have existed substantially the same as now ever since, and probably before, this earth was condensed into its present nearly globular shape. So now, as man begets man, life begets and has begotten life, and there can be no new life except from antecedent life. We could never have had life, according to the present 86 WHAT IS LIFE? laws of nature, unless there was antecedent life. But there must have been an original life; and that original, or first life could not have been begotten, from the want of any pre- existing life to beget it; and hence we are forced to the con- clusion that this original life was self-existent. Advocates of the spontaneous generation theory, however, try to avoid this last conclusion by assuming that " spon- taneous generation ” existed in the early ages of the earth; and they assume this without definite evidence that such a thing ever existed, and against what appears to be almost conclusive evidence that it has no present existence. Now let some one show that, from the nature of the case, there could not be an original, self-existent, living, intelli- gent being, and then I will confess the reasonableness of the wildest scepticism concerning a belief in an original self- existent creator. But in default of this, I must insist that it is reasonable to believe that all the life of which we see the manifestations is derived from a self-existent fountain of life, and is produced through infinite creative power. How life comes into existence through secondary causes and is developed through the laws of nature will be con- sidered in other chapters. DEVELOPMENT THEORIES. 87 CHAPTER, IY. DEVELOPMENT THEORIES. In a previous chapter I inquired respecting the origin of life, and it is now proper to examine various theories concern- ing development of life; for some biologists assert that all present living beings have descended from one common ancestor. One of these theories is known as the hypothesis of Lamarck; another, the Darwinian, a great advance and improvement upon Lamarck’s. Some who advocate these or like theories think they see a complete chain of life from the lowest to the highest types. There is a common tendency among many who advocate radical development theories to accuse such as cannot see the consistency of extreme theories of lacking intelligence, or in effect saying that the reason why some men do not understand and fully accept these theories is because of their ignorance, or want of logical power. It is well known that Sir Charles Lyell, the eminent geolo- gist, came reluctantly to agree to a part of Darwin’s theories. In commenting upon this reluctance, Prof. Allen, in his bio- graphical sketch of Lyell in "Popular Science Monthly,” March, 1882, writes ; " I have illustrated this matter thus fully because it is one which very clearly shows the weak side of Lyell’s intellect. With all his breadth of mind and freedom from prejudice, he was not ever one of those who really get to the deepest bottom of things. His tendencies were all in the 88 THE DEVELOPMENT OF LIFE. right direction, and his instinct always inclined him to the true solution ; but he did not build himself up a set of first principles to start with, firmly based upon a philosophical foundation, and make these the fixed criteria of his judgments throughout.”1 In Mr. Allen’s article I find no other facts stated which indicate any lack of deep reasoning, except this one, viz., that it did not comport with Lyell’s judgment to readily and fully embrace the popular development theories, including the supposed descent of man from ape-like mammals. I mention this instance —by no means an uncommon one— from the fact that I have been particularly struck with the number of statements which occur in the writings of certain authors charging a lack of intelligence against those who do not accept doctrines of radical evolutionists. That all life on the earth is modified by, or made to con- form to, external as well as internal conditions is so per- fectly natural that it was impressed upon the writer’s mind before he has any recollection of learning that it was taught by men of science. If we vary the conditions surrounding us, whether in regard to climate, light, heat, or moisture, those very changed conditions must modify the physical sys- tems of men, and with these physical modifications will come somewhat analogous mental changes. For instance, the reason that most of the inhabitants of Africa are negroes is not necessarily because they originally sprung from black progenitors, but rather because of the physical character- 1 David Hume would hardly agree with Mr. Allen in regard to making a set of “first principles “fixed criteria of judgments throughout.” He says (Essays, p. 93), “ When a philosopher has once laid hold of a favorite principle which per- haps accounts for many natural effects, he extends the same principle over the whole creation, and reduces to it every phenomenon, though by the most violent and absurd reasoning.” INFLUENCE OF CLIMATE. 89 istics of that continent taken in connection with habits of living through many generations. These peculiar character- istics, however, originated anterior to any historical records. When European nations have colonized tropical countries, the descendants of these colonists have not taken on the peculiar characteristics of negroes, but generally, after a few generations, these descendants have ceased to produce off- spring, and hence the races have run out. This fact strik- ingly shows how necessary certain environments are to the very existence of any race. Had these descendants been able to continue through many generations, perhaps some traits of negroes might have appeared in them. Different races of animals and men live on the earth be- cause the earth is fitted to be their place of residence, and not because they were first made to live whether their physical surroundings were suitable or not. Make the physical changes in the character of the earth great enough, and not a human inhabitant could exist upon it. Doubtless evolution through natural selection has had an immense influ- ence in shaping the character and kinds of life, but it is doubtful whether it has done all that the ardent advocates of the doctrine believe it has. Guyot teaches that even the mountains and the sound of the winds of a country will cause harshness or melody in the sounds of human language. To a certain extent man must O o be dependent upon physical environments; and whatever doctrines we may advocate concerning the origin and descent of species, and however great or however little stress we may lay upon the laws of heredity, natural selection, or any other theory of evolution, we must admit that the operations of laws of evolution go far beyond mere animals and plants. They probably extend even to the formation of worlds ; and 90 THE DEVELOPMENT OF LIFE. yet no man ever saw any one race of beings transformed into another distinct race. The general positions of evolutionists are probably correct, yet it does not necessarily follow that all their assumptions are correct. Among those which may be fairly considered of doubtful character may be mentioned that of the supposed development of the human race from a catarrhine species of apes. It may be asked, why, if the writer is inclined to think that the theory of the descent of men from animals some- what resembling apes may be shown to be probably true, he does not say so, and let the matter rest there? He does not desire to express any decided opinion con- cerning the actual scientific value of this hypothesis ; but the conviction is forced on his mind that, whether the hypothesis is correct or incorrect, it is put forth by radical evolutionists with a greater degree of positiveness than our present knowl- edge on the subject justifies. But this theory now seems to be making strong headway, and carries before it most of those who do not stop to question the validity of widely prevalent ideas, and it has all the advocates it needs. The danger now is that important facts which appear to point in another direction may be overlooked. If, however, the writer must choose between the old belief in several universal cataclysms, by which all the animals which have inhabited the earth at certain geological periods have been suddenly swept entirely off and a new set of ani- mals suddenly created by successive almighty fiats, and the doctrine that the various species of animals which now in- habit the earth have been developed by infinitesimal and almost imperceptible accretions through immense ages from previously existing varieties, and these from one or more EARLY RACES OE MEN. 91 original germs, he thinks there is no doubt that the latter theory agrees better with what we know of the workings of nature’s laws, and thus it may seem probable that man is really of animal extraction ; but, if so, it is likely that the race branched off long before the state of apehood was reached, and some reasons for this opinion can be given. My efforts will be directed toward showing that this descent might not be through apes, and facts will be produced which throw doubt upon his animal extraction. The writer takes ground in common with evolutionists on certain points as stated by Prof. Edward S. Morse in "Popular Science Monthly,” December, 1876, p. 189, viz. : " If man has really been derived from an ancestor in common with the ape, we must expect to show, first, that in his earlier stages he recalls certain persistent characters in the apes ; second, that the more ancient man will reveal more ape-like features than the present existing man ; and, third, that certain characteristics pertaining to early men still per- sist in the inferior races of men.” Prof. Morse then devotes several pages attempting to prove that such characteristics do pertain to the earliest races of men. He cites measure- ments and descriptions by Prof. Wyman of certain skulls and bones found in the United States, and microcephalic skulls from other places, and also mentions the Neanderthal and Engis skulls. Why he does not quote from the Duke of Argyll, who writes concerning an ancient skull, " This most ancient of all known human skulls is so ample in its dimensions that it might have contained the brains of a philosopher,” the writer does not know. Suffice to say, however, that from the evidence which he mentions, Prof. Morse draws the conclusion that, "To a mind unbiassed by preconceived opinions, and frankly willing 92 THE DEVELOPMENT OF LIFE. to interpret the facts as they stand revealed by the study of these ancient remains the world over, the evidence of man’s lowly origin seems, indeed, overwhelming.” Notwithstanding the apparent probability that Prof. Morse is correct in this conclusion, the evidence given does not appear to be " overwhelming.” But, without taking excep- tion to the excellent spirit in which the Professor writes, I cannot help remarking that here indeed trouble comes, perhaps from " preconceived opinions ; ” but it is pertinent to ask whether it was on account of " preconceived opinions ” that Virchow declared at Munich that " at this moment there are few naturalists who are not of opinion that man is allied to the rest of the animal world. Vogt is of opinion that a con- nection will be found, if not with apes, then, perhaps, in some other direction. I should not be alarmed if proof were found that the ancestors of man were vertebrated animals. I work by preference in the field of anthropology, yet I must declare that every step of positive progress which we have made in the domain of prehistoric anthropology has really moved farther away from the proof of this connection.” He further states that, " only ten years ago, when a skull was found in peat, or in the lake dwellings, a wild and undevel- oped state was seen in it. We were then scenting monkey air. But these old troglodytes turn out to be quite respectable society.” Some may try to evade the force of this by asserting that Virchow is not a consistent evolutionist. But on p. 840, " Popular Science Monthly,” October, 1882, the following statement occurs concerning Virchow : " His attitude tow- ards Darwinism has been likewise misapprehended. Far from being an opponent of Darwinism, he should be regarded as one of its forerunners.” EARLY RACES OF MEN. 93 Is it on account of " preconceived opinions ” that Prof. Boyd Dawkins (who is styled by Grant Allen a " consistent and bold evolutionist ”) states that, in his opinion, the "cave ” or " river-drift ” men were fully equal to the modern Esqui- maux ? Is it on account of " preconceived opinions ” that Dr. Mitchell, of Edinburgh, gives his opinion that the " cave men ” were fully equal to the present races of savages, if not equal to the present average Englishmen? Now let us shift our question. Was it on account of " preconceived opinions ” that a great many evolutionists ten years since were " scenting monkey air ? ” and so much so that questionable facts concerning certain peculiarities per- taining to fossil specimens of men and animals were colored to make them support the opinions of those who believe that man must of necessity have descended from ape-like ances- tors? This disposition to grasp every fact which is doubt- ful in character, and claim that the very fact of its being doubtful argues in favor of the animal descent of man, appears to be prima facie evidence that such claimants are at least partially aware that no unequivocal evidence pointing directly to such animal origin has been dis- covered. Some writers suppose that the fossil human skulls, con- cerning which so much has been written, may not have belonged to primitive men at all. These men might have lived upon the outskirts of a much higher civilization then existing, and at the same time in other parts of the earth much higher races of men may have lived. The difference of the style of living and the culture may have been as great between men inhabiting Egypt and Europe in those remote times as the difference which now 94 THE DEVELOPMENT OF LIFE exists between the highest nations of Europe and the pres- ent Egyptians. When the men who bore the Engis and Neanderthal skulls were living and acting their parts, races of much higher culture and mental ability may have lived in locali- ties around Persia, China, or Babylonia. Who knows to the contrary ? The real value of any hypothesis may be approximately known by the number of facts which it fairly explains, or which are fairly explained by it. For instance, if out of ten well-known facts nine appear to perfectly agree with or be consistent with an hypothesis, and only one known fact is apparently inconsistent with the supposed hypothesis, then, generally speaking, we may say that there are nine chances in ten that the hypothesis is a correct one. If one fact appears utterly inconsistent with the hypothesis, then we may justly reject the hypothesis, or hold the theory provi- sionally, and look for further light. Thus, with the general theory of evolution, so many facts appear to be perfectly consistent with it, and so few appar- ently inconsistent with it, it must be confessed that the prob- abilities of its general correctness greatly outweigh the probabilities that it is not correct. But it is one thing for a general theory to be correct, and quite another to assert that all the apparent inferences from that theory must of necessity be correct. Let us now briefly examine the common assertion that if the workings of nature are always consistent, man must of necessity have descended through the lower animals. That a healthy reaction against inordinate haste to assume as proved the statement that man must have descended from ape-like animals has set in is one of the favorable signs of LAWS OF DEVELOPMENT. 95 the times. If we are to proclaim such an origin, let it be from proper evidence, and not by jumping to a conclusion from a limited number of specimens. According to Virchow, as above quoted, the latest geological and paleontological evidence seems to point away from rather than towards proof of man’s animal extraction. Narrowed down, the question at issue is, Are the laws relating to the origin and development of man in any way different from those pertaining to the origin and development of the rest of the animal creation? or, Was the way or method of man’s creation in any way different from that by which other animals were originally produced? The writer does not presume to assert that man was pro- duced by an exceptional method ; but he does assert that the contrary has not been shown ; and some facts would seem to indicate that the laws relating to the production of man may possibly have been different from those which were most active in the origin and development of other animals. Huxley pertinently remarks in regard to his own opinions : "We scientific men get an awkward habit —no, I won’t call it that, for it is a valuable habit —of reasoning, so that we believe nothing unless there is evidence for it; and we have a way of looking upon belief which is not based upon evi- dence not only as illogical but as immoral.” But the particular point to which attention will be first called is not so much the question of actual fact concerning the line of man’s descent as the dogmatic style of argument favored by some radical advocates of the theory of man’s descent from pithecoid ancestors. These dogmatic assertions are repeated, notwithstanding the fact that such a competent anthropologist as Quatrefages says that certain changes in the skulls of men and apes as they go from youth to adult 96 THE DEVELOPMENT OF LIFE. life show that man could not have descended from a pith- ecoid ancestor. In the "Contemporary Review” for March, 1883, Rev. George Edmundson writes as follows: " Popular scientific lecturers and writers have acquired in these days a very unpleasant habit of dogmatism. They assume an air of infallibility, and express in no measured language their mean opinion of those who do not swallow a new-fangled doctrine, however unpalatable or distasteful, without making one wry face. Science is declared to be the unerring guide to all truth and its teachings. Well, 'New professor is but old prophet writ large.’ Not such is the spirit of truly great discoverers and thinkers, men of the stamp of Newton and of Darwin : such men are always modest and reserved in their assertions; but the mantle of the master does not always descend upon the disciple.” Dr. Lionel Beale, several years since also noticed the tendency to disparage the intelligence of disbelievers in certain theories, and writes (pp. 103, 104, "Matter of Life ” ) : " If a physical writer should be in any doubt about gaining the desired number of converts to his views, and should feel a little misgiving lest some of his readers might not be inclined to accept the conclusions upon which he de- sired they should rely, it would be easy for him to add to his arguments a little literary terrorism. He might remark with effect, that, ' an argument like the above must, indeed, be convincing to any one who possesses any mind at all. He who hesitated to accept such a demonstration would thereby prove himself to be foolish, or savage, or both; ’ and so forth, the metaphors being varied from time to time to suit the circumstances of each particular case.” Even so eminent a naturalist and scholar as Haeckel, a LITERARY TERRORISM. 97 man who ought to be above all attempts at intellectual or literary terrorism, is moved to say (p. 332, "History of Crea- tion,” vol. 2) : "The recognition of the theory of development and the monistic philosophy based upon it forms the best criterion for the degree of man’s mental development.” On the contrary, it may be confidently asserted that there is now a large proportion of partial students of natural history who accept so-called scientific statements which they cannot com- prehend, in a way quite analogous to what obtained during the middle ages, when men accepted theological dogmas they could not comprehend; and their fears of the social conse- quences from rejection of scientific dogmas are as real though of a somewhat different kind. Hence you will fre- quently hear men who confess they never read a page from the writings of Darwin, Lamarck, or Hseckel say, "Well, it really seems that the evolutionists have proved their case ; for nearly all intelligent scientific men have accepted the doc- trines of evolution.” However, there are several rational examples of men in high position who indorse Darwin in the main, and honestly state their positions, and also as honestly state that part of Darwin’s hypothesis has not been proved, and in fact may be incapable of proof in our present state of knowledge. Among such authors may be mentioned Darwin himself and Huxley. They certainly have done much to help men in important lines of investigation. But we meet two classes of evolutionists : the one recog- nizes an intelligent power behind and directing all the phe- nomena of evolution; while the other can see only a blind and unintelligent force directing nature’s laws, but concern- ing the nature of which force we are and must be in total ignorance. This last class is apt to be the most positive in 98 THE DEVELOPMENT OF LIFE. their assertions that their propositions must inevitably prove correct. But the constant repetition by the atheistic that certain supposed ways of working by the Creator are not scientific, and that those who do not assent to those assertions are either ignorant or illogical, is of questionable taste, to say the least. Can such bind the Creator to work just in their own way or not at all ? Who is the author of the very laws of nature? We grant that if the Deity in creating man has chosen to work upon the Darwinian or Lamarckian plan He has the power and right to do so, just as well as upon some other plan. The simple question at issue is one of fact, viz., has He done so? All statements that He must have done so, and that it would be unscientific to suppose He could do any other way, are the merest non-sequiturs, and the pretence that science has thrown any decisive light on the way life first came into existence is the boldest quackery, as all careful students of facts concerning life’s origin well know. If the rocks show that creation came about in a certain way, bring out the facts. Facts, and not unsupported theories, are what we want. Huxley has well described what should be understood by scientific reasoning; and it is but just to say that, while all proper deference should be paid to scientific statements, there is as much real scientific cant as there is religious cant. On p. 57, "Origin of Species,” Huxley writes as follows: "You have all heard it repeated, I dare say, that men of science work by means of induction and deduction, and that by the help of these operations, they, in a sort of sense, SCIENTIFIC INVESTIGATIONS. 99 wring from nature certain other things, which are called natural laws, and causes, and that out of these, by some cunning skill of their own, they build up hypotheses and theories. And it is imagined by many that the operations of the common mind can be by no means compared with these processes, and that they have to be acquired by a sort of special apprenticeship to the craft. To hear all these large words, you would think that the mind of a man of science must be constituted differently from that of his fellow-men; but if you will not be frightened by terms you will discover that you are quite wrong, and that all these terrible apparatus are being used by yourselves every day and every hour of your lives.” " Probably there is not one here to-night who has not in the course of the day had occasion to set in motion a complex train of reasoning, of the very same kind, though differing of course in degree, as that which a scientific man goes through in tracing the causes of natural phenomena.” In another place he says (pp. 54, 55) : "I must dwell a little on tliis point, for I wish you to leave this room with a very clear conviction that scientific investigation is not, as many people seem to suppose, some kind of modern black- art. I say that you might easily gather this impression from the manner in which many persons speak of scientific inquiry, or talk about inductive and deductive philosophy, or the principles of the' Baconian philosophy.’ I do protest that, of the vast number of cants in this world, there are none, to my mind, so contemptible as the pseudo-scientific cant which is talked about the ' Baconian philosophy.’” As Huxley further explains, if you buy an apple that is hard and green, and you find it sour, and then buy another hard and green, and find the same result, you suspect that 100 THE DEVELOPMENT OF LIFE. all hard and green apples may be sour. This is inductive reasoning. Does not any farmer’s boy know enough to reason in this way? But suppose he should afterwards find apples that were hard and green which were not sour, then he would say that the conclusions he drew from the first two apples were wrong in certain cases, and he would also see that his first deduction was wrong, or at least that his rule was not of universal application. The great trouble with present scientific men is that they are inclined to go too fast, and draw their conclusions from too few facts. And this is especially true in regard to theories claimed to result from the teachings of geology. On p. 38, "Origin of Species,” Huxley writes, concerning the amount of our geological knowledge, as follows : " Under these circumstances it follows that, even with reference to that kind of imperfect information which we can possess, it is only about the ten-thousandth part of the accessible parts of the earth that has been examined properly. Therefore, it is with justice that the most thoughtful of those who are concerned in these inquiries insist continually upon the im- perfection of the geological record; for, I repeat, it is ab- solutely necessary, from the nature of things, that that record should be of the most fragmentary and imperfect character. Unfortunately this circumstance has been constantly for- gotten. Men of science, like young colts in a fresh pasture, are apt to be exhilarated on being turned into a new field of inquiry, and to go off at a hand-gallop, in total disregard of hedges and ditches, losing sisrht of the real limitation of their O 7 o o inquiries, and to forget the extreme imperfection of what is really known. Geologists have imagined that they could tell us what was going on at all parts of the earth’s surface during a given epoch ; they have talked of this deposit SCIENTIFIC REASONING. 101 being contemporaneous with that deposit, until, from our little local histories of the changes at limited spots of the earth’s surface, they have constructed a universal history of the globe as full of wonders and portents as any other story of antiquity.” This is the candid testimony of a strictly scientific man ; for in his writings I have never seen any intimation that he believes in any supernatural revelation. His book of revela- tion consists of science and its teachings. The human intellect is a wondrously complicated piece of machinery, and men equally intelligent and equally learned differ in their conclusions when the same facts are placed before them. Especially is this true in matters where truth must be definite and cannot contradict itself. One would naturally suppose that scientific reasoning from the same data would invariably lead to the same conclusions ; but the fact is quite the reverse. Especially is this so in regard to the matter of our previous inquiry, " Whence is life?” And like differences arise concerning the other question which we now have under consideration, viz., given life already orig- inated, how has it been developed into the living creatures we now see around us ? When examining this question, certain evidence will weigh heavily in one mind, and the same evidence be considered very light by another mind. When searching for scientific truth all agree that we ought to lay aside all prejudice, and come with the most sincere desire to ascertain just what the exact truth is ; and it is of no consequence, so far as actual truth is concerned, whether one man believes a fact to be truth or not: truth is always truth; and no man’s opinion can alter an actual fact. 102 THE DEVELOPMENT OF LIFE. But, when we try to philosophize about truths which are, in a measure, concealed, the opinions of intelligent men who have investigated these lines of truth should have due weight in shaping our opinions. This is especially true respecting certain statements, which, from their very nature, must be hard to comprehend; for we should bear in mind, in regard to many assertions concerning the origin and development of life, that, with our present knowdedge, we cannot with certainty tell whether they are based on truth or not, though we well know that they must be either true or false. I cannot better illustrate this than by comparing the opin- ions of two learned naturalists, Louis Agassiz and Ernst Haeckel, in regard to the origin of species. Agassiz came to the investigation of this question with a great reverence for the Creator of all things, whom he believed to be an Almighty Intelligence. Haeckel comes to the subject from an exactly opposite stand point. However, when we attempt to compare the opposite posi- tions taken in their published works in regard to the origin of species, we should bear in mind that the " Classification of Species,” by Agassiz, was written before the publication of Darwin’s " Origin of Species ; ” and if Agassiz had had the benefit of Darwin’s investigations previous to writing his " Classification ” doubtless he would have written differently in several respects. One test of the clearness with which any debater sees his conclusion may be observed in his manner of carrying on the discussion. The man (other things being equal) most cloudy in his appreciation of the exact truth is most likely to lose his temper in the discussion, and perhaps accuse his opponent with not properly treating the subject, or of being DISCUSSIONS. 103 ignorant and lacking intelligence. Above all, when discuss- ing a subject concerning which neither knows with certainty what the truth is, this bitterness is likely to be manifested. Cloudiness of perception has been the fruitful source of religious persecution. Because religious bigots could not demonstrate their statements to be true, and because their declarations were not received for truth without demonstra- tion, the fagot and the Inquisition have been brought into requisition. Let us lay it down as a general rule in scien- tific as well as in religious discussions that the party who sees most clearly the truth will be most tolerant of the mis- takes of opponents, especially when he has reason to believe these mistakes are honest ones. Because of his confidence in what he believes to be true he will have additional con- fidence that he can make others see the truth, and thus can afford to wait till time shall make the facts plain. I propose to quote somewhat from the writings of various authors, that the reader may get a clear idea of the wide divergence of conclusions at which they arrive, while each has the same facts from which to draw his conclusions. All scientific investigations, however, should be based on the rejection of all hypotheses that apparently contradict common-sense until such hypotheses are proved true be- yond reasonable doubt. Men naturally love new views, and if these views tend to undermine long-settled convictions, the charm is all the greater, with a large proportion of studious men. It must be admitted, however, that some (through previous habits of thought) hold on to antiquated ideas, when it would be much better if they would open their minds to receive new views of truth. Dr. Haeckel states the radical evolutionary position as 104 THE DEVELOPMENT OF LIFE. follows (vol. 2, "History of Creation,” p. 278) : "The most ancient ancestors of man, as of all other organisms, were liv- ing creatures of the simplest kind imaginable, organisms without organs, like the still living monera. They consisted of simple, homogeneous, structureless and formless little lumps of mucus, or albuminous matter (protoplasm), like the still living Protamoeba primitiva.” " The form value of these most ancient ancestors of man was not even equal to that of a cell, but merely that of a cytod, for, as in the case of all monera, the little lump of protoplasm did not as yet possess a cell-kernel. The first of these monera originated in the beginning of the Laurentian period, by spontaneous generation, or archigony, out of so-called ' inorganic com- binations,’ namely, out of simple combinations of carbon, oxygen, hydrogen, and nitrogen.” "The assumption of this spontaneous generation, that is, of a mechanical origin of the first organisms from inorganic matter, has been proved, in our thirteenth chapter, to be a necessary hypothesis.” The way Hseckel proves this is shown by the following extract from vol. I, " History of Creation,” pp. 347, 348 : " The origin of the first monera by spontaneous genera- tion appears to us as a simple and necessary event in the process of the development of the earth. We admit that this process, as long as it is not directly observed or re- peated by experiment, remains a pure hypothesis. "But I must again say that this hypothesis is indispensa- ble for the consistent completion of the non-miraculous history of the creation, that it has absolutely nothing forced or miraculous about it, and that certainly it can never be positively refuted.” But we are not yet through our difficulties. If we admit 105 HiECKEL’S THEOEY. that probably the origin of all life came through spontaneous generation of monera, how many of these monera were at first so generated? Did all life descend from one single original microscopic speck, that is from one single moner? To make Hasckel’s theory consistent, it seems to me that we must presume that all living beings are either descended from one single original moner, or else suppose that mo- nera may still be spontaneously generated. The gist of his argument is this : that this spontaneous generation hypothesis " can never be positively refuted,” and does not necessitate anything miraculous about creation, and, notwithstanding there never has been any proof of its ex- istence either by experiment or observation, yet, as the hypothesis seems perfectly consistent, and cannot be " posi- tively refuted,” it should be received and considered to be true. Here the doctor completely begs the question when he assumes that the creation was non-miraculous; for the question whether it was or was not miraculous contains the gist of the whole matter in dispute. If he was possessed of infinite knowledge, and was in every way infallible, his authority would constitute a final answer to the question. But, being of a sceptical turn of mind, I am led to ask, what does this announcement prove, according to his own state- ments ? Is it not clearly this, viz. : that it is necessary to assume that life came through spontaneous generation, or his doctrine that life and its development can be accounted for through non-purposive causes cannot stand ? " Spon- taneous generation” is a thing that no man ever saw (as Hasckel himself admits), and, according to the most careful scientific tests, has no present existence, and, in so far as we know, the laws of nature have not changed since they were first instituted, and there seems to be no good reason to be- 106 THE DEVELOPMENT OF LIFE. lieve that " spontaneous generation ” ever took place. Then would not one naturally infer that he has built his mechani- cal or chemical theory of the origin of life upon a foundation which probably never had an existence ? He seems to prophesy, as Huxley expresses it, "back- wards,” and somewhat as Moses did when he wrote, "In the beginning God created the heavens and the earth.” But his statement is varied to suit the advanced knowl- edge of present times. Instead of being simply, "in the be- ginning,” it is, "in the beginning of the Laurentian period” the ancestors of men were not created, but spontaneously generated. He does not attempt to tell us how long ago this took place, but we infer from other statements that the Laurentian period must have been since the earth became cool enough to condense the hot mist, or steam that once enveloped the earth, into water. We accept this supposition about the temperature of the earth before animal or plant life could exist, inasmuch as it was stated by Thales, six hundred years before Christ, that no animal life could exist without water, and that life came from water : and a statement which has gone so many years without being successfully contradicted must be supposed to be true. But suppose it should be shown that it is highly probable that life existed on the earth long ages before the " beginning of the Laurentian period,” how will that comport with the positive assertion that the "most ancient ancestors of man as of all other organisms” " originated in the beginning of the Laurentian period ” ? Prof. Fiske, in vol. 2, p. 39, "Cosmic Philosophy,” says : " It is now generally admitted that even the Laurentian strata are modern compared with the beginnings of life upon our globe.” DU BOIS REYMOND. 107 In reference to an address of Du Bois Reymond, at Leipzig, in 1873, Haeckel says, p. xx., "Evolution of Man” : " This eloquent address, the source of such triumph to the opponents of the theory of evolution, the cause of such pain to all friends of intellectual advance, is essentially a great denial of the history of evolution.” In that address Du Bois Reymond asserts, concerning the origin of sensation and consciousness, " We shall never know that 'lgnorabimus.’ ” On p. xxi. he writes : "With this 'lgnorabimus ’ the Berlin School of Biology tries to stop science in its advance along the paths of evolution. This seemingly humble but really audacious ' Ignorabimus ’ is the ' Ignoratis ’ of the infallible Vatican and of the 'Black International’ which it leads; that mischievous host against which the modern civilized state has now at last begun in earnest ' the struggle for culture.’ ” It is difficult to see just what the infallible "Vatican” has to do with this fact in natural science. Either Haeckel is right, or he is wrong, in his assumptions concerning the origin and development of life and consciousness, and whether he is right or wrong must be decided by the teach- ings of natural scieiice. A scientific fact cannot be changed by scientists, or by statements of pope, cardinal, bishop, or any other eccle- siastic. Facts in natural history cannot be altered; but there evidently is a limit somewhere to our knowledge, and intelligent men differ as to where this line is to be drawn. If Du Bois Reymond thinks we shall never understand the origin of consciousness, and Mr. Haeckel thinks we shall understand this origin, let Haeckel show plainly the how of the existence of this origin, and we will believe in him. But run- ning away from the question to anathematize pope, cardinals 108 THE DEVELOPMENT OF LIFE. and churches cannot help us to the desired information. So, of the origin of life, if Eheckel can demonstrate that his order in creation is correct, or the fact that original " spontaneous generation ” took place, let him do so, and then we must believe in him, nolens volens. But if Du Bois Reymond differs from him in opinion respecting what are actual facts in natural history, or thinks we can never know for a certainty what are the actual facts in certain phases of the development of life and intelligence, why, on that account, should the Berlin physiologist and the Berlin School of Biology be accused of working to sustain, or in harmony with the " Black International,” whatever that may mean? Much has been written about man’s place in nature, and the attempt has been made to show that man has had, and still continues to have, false opinions concerning the impor- tance of the position he holds in nature, and the tendency of the writings of several of the most prominent naturalists has been to show that man has no right to believe he is a being o O " destined for eternity ” or to an immortal existence. They further intimate that this supposition, or rather " delusion,” about immortality, in which man indulges, warps his reason- ing when considering facts concerning his origin. Also that his belief in immortality makes him think he occupies a radically different sphere from that occupied by other animals, and this gives him false and altogether too exalted ideas of his actual place in nature. But, query : If a belief in immortality warps his reasoning powers in one way, will not the non-belief in immortality warp the reasoning powers in another way ? Is it possible that be- lief in oneway will warp a sane man’s mind in one direction, and that non-belief may not warp his mind in another direction ? LAMARCK AND DARWIN. 109 On reading Hreckel further, we find another astonishing truth (provided it is truth) stated as follows : In vol. 2, "History of Creation,” p. 264, he writes : "Just as the geo- centric conception of the universe namely, the false opinion that the earth was the centre of the universe, and that all its other portions revolved around the earth was overthrown by the system of the universe established by Copernicus and his followers, so the anthropocentric conception of the universe the vain delusion that man is the centre of terrestrial nature, and that its whole aim is merely to serve him is overthrown by the application (attempted long since by Lamarck) of the theory of descent to man. As Coper- nicus’ system of the universe was mechanically established by Newton’s theory of gravitation, we see Lamarck’s theory of descent attain its causal establishment by Darwin’s theory of selection.” But if it shall be shown that Lamarck’s theories are merely suppositions, and far from being demonstrated, and that some parts of Darwin’s hypotheses are as yet far from receiving anything like proof; and if we shall find that in our present state of knowledge it is actually impossible to attain to proof of the correctness of these assumptions con- cerning the descent of man, will not this indicate that the assertions of the doctor are too positive? Let us see what Huxley (who is one of the strongest supporters of Darwin’s views) says of the principal part of Lamarck’s hypothesis. In "Origin of Species” (p. 144), he says: "Take the Lamarckian hypothesis, for example. Lamarck was a great naturalist, and, to a certain extent, went the right way to work. He argued from what was un- doubtedly a true cause of some of the phenomena of organic nature. He said it is a matter of experience that an animal THE DEVELOPMENT OF LIFE. may be modified more or less in consequence of its desires and consequent actions. Thus, if a man exercise himself as a blacksmith his arras will become strong and muscular; such organic modification is a result of this particular action and exercise. Lamarck thought that by a very simple sup- position based on this truth he could explain the origin of the various animal species; he said, for example, that the short-legged birds, which live on fish, had been converted into the long-legged waders by desiring to get the fish with- out wetting their feet, and so stretching their legs more and more, through successive generations. If Lamarck could have shown experimentally that even races of animals could be produced in this way, there might have been some ground for his speculations. But he could show nothing of the kind, and his hypothesis has pretty well dropped into oblivion, as it deserved to do.” Now, if, on further investigation, it should appear that parts of Darwin’s theory of the descent of man may possibly be- long alongside of Lamarck’s, which "dropped into oblivion, as it deserved to do,” what will become of the doctor’s demon- stration founded upon Darwin’s hypothesis ? Haeckel considers Lamarck to be the real founder of Darwin’s theory, for (on p. 85, vol. 1, "Evolution of Man,”) he says : " These are the principal outlines of the theory of Lamarck, now called the theory of descent or transmutation, and to which, fifty years later, attention was again called by Darwin, who firmly supported it with new proofs. Lamarck, therefore, is the real founder of this theory of descent or transmutation, and it is a mistake to attribute its origin to Darwin. Lamarck was the first to formulate the scientific theory of the natural origin of all organisms including man, and at the same time to draw the two ultimate inferences MAN’S PLACE IN NATURE. from this theory; firstly, the doctrine of the origin of the most ancient organisms through spontaneous generation ; and, secondly, the descent of man from the mammal most closely resembling man, the ape.” But let us see how Mr. Huxley agrees with Haeckel upon this point. Huxley (in "Origin of Species,” p. 144) says : " I said in an earlier lecture that there are hypotheses and hypotheses, and when people tell you that Mr. Darwin’s strongly-based hypothesis is nothing but a mere modification of Lamarck’s, you will know what to think of their capacity for forming a judgment on this subject.” I suppose that most men who give careful attention to this subject at once perceive that the moving forces in Lamarck’s and Darwin’s theories come from radically different points. Lamarck’s initiatory impulses towards development come from wants within the organism ; while the modifying powers, according to Darwin’s theory, generally come from without, or through the environments. But, in trying to fix the proper sphere of man in the animal creation, Haeckel looks at him as a mere animal, and would dissect him as he would a frog or a horse, simply to find out his physiological, morphological, and anatomical structure, regardless of any difference in mental structure between man and other animal existences. In so far as he confines himself to the mere physical structure to the exclu- sion of all mental characteristics, he may be fair if he states that that is all he is looking for, and providing he does not deny that he ought to take into consideration the mental characteristics when he attempts to fix man’s full station. But he cannot find man’s full sphere without taking into consideration his peculiar mental qualities as distinguished from those of the brutes. Haeckel has told us that we must, 112 THE DEVELOPMENT OF LIFE. for the time being, divest ourselves of all our " deep-rooted prejudices” which we have imbibed in our youth, and leave out of consideration all our notions respecting the " spiritual sicfe” of our natures, if we would arrive at the genuine truth respecting our descent. But if we would arrive at the genuine truth of our inheritance, we must take into con- sideration all of the facts bearing on the case ; and we shall be more liable to arrive at false conclusions if we try to restrict the field of observation. Mental as well as physical characteristics are inherited; and my point is, that if there is an essential difference in the mental constitutions of men and the brutes, or a difference so great and marked as to make it appear evident that one mental constitution could not be inherited or developed from the preceding one, then this very fact would seem to show that the physical side, so intimately connected with the mental, could not be inherited from any ape-like animal. A mere naturalist examining man in physical structure only, as he would a bug or a bee, does not take into con- sideration the whole man. 113 MAN’S RANK IN NATURE. CHAPTER V. MAN IN HIS COMPOUND NATURE. Man is a compound animal, having mind as well as body. If it is of no consequence whether there is a radical difference between men and brutes in their mental structures, then to compare them only anatomically or physiologically is fair. But there appears to be a radical mental difference, and hence it is not fair to compare men with mere animals by the physiological organization alone, and by such comparison attempt to fix man’s real rank in nature, for nature comprises the mental as well as physical organization. It may be said that beasts have mental traits in many respects like men, granted; but it is not granted in the highest and most im- portant respect. True, the beasts have loves and hatreds, joys and sorrows, somewhat analogous to those of men; but their sorrows differ from men in this, that the very elements which add depth and intensity to the pangs of sorrow in men arise from their reflective faculties, and their feelings of joy are often most active in anticipation of some future good. There is, however, a disposition to be faithful in some beasts, and some will defend their acquired possessions like men. Dogs lament the loss of friends, as instances of watching the graves of their masters will show. Animals have memory; and the growth and decay of their bodies areas regular as with men. We may be asked who knows that the lives of the brutes are not coexistent with those of men? If man has a soul, who knows that brutes 114 THE DEVELOPMENT OF LIFE. have no souls? In what does man differ from brutes except in the degree of intelligence? This question is a fair one. But we know what men desire and think about and talk about. We know they have hopes and fears concerning a future life, and these hopes and fears seem to be inborn ; but we have no evidence that brutes have the least idea of any future or spiritual existence; and we have absolutely no evidence that they have the least apprehension of anything pertaining to a spiritual life. But we do know that in many intelligent men one of the very strongest of all desires centres in the hope of eternal life, or of a conscious existence after death. Many have suffered death in its most repulsive forms rather than speak one word indicating a doubt of the realities of a spiritual existence. If we call these hopes and fears superstitious, that does not alter the fact of their existence, nor does it explain how these hopes and fears came to exist. Notwith- standing the high authority claimed in favor of the ghost theory, or that the belief in another or spiritual self originally came from dreams, that does not satisfactorily explain how men originally came to believe that they possess an immortal self. Peschel, in regard to another radical difference, says (p. 5, " Races of Men ”) : "We cannot conclude these obser- vations without answering the accusation, which may per- haps be silently made, that we leave out of sight the intel- lectual functions of mankind. We at once repeat what Darwin has already said, that the motions of conscience as connected with repentance, and the feelings of duty, are the most important differences which separate us from the ani- mal ; that in the latter there is no capability of solving a mathematical problem, or of admiring a landscape painting, MR. WALLACE. 115 or a manifestation of power. Neither can any reflection take place respecting the correlation of phenomena, and still less as to the hypothesis of a First Cause or a Divine Will.” Hear Mr. Wallace, a naturalist of no mean order, who was getting ready to publish his own theory of development when, in 1859, Darwin hurried up the publication of his book (quoted by Mivart, p. 301): "Mr. Wallace ob- serves, that on his view man is to be placed 'apart,’ as not only the head and culminating point of the grand series of organic nature, but as in some degree a new and distinct order of being.” Also, on p, 302, Mivart has the follow- ing : "At length, however, there came into existence a being in whom that subtle force we term mind became of greater importance than his mere bodily structure. Though with a naked and unprotected body, this gave him clothing against the varying inclemencies of the seasons. Though unable to compete with the deer in swiftness, or with the wild bull in strength, this gave him weapons with which to capture or ovei’come both. Though less capable than most other animals of living on the herbs and the fruits that unaided Nature supplies, this wonderful faculty taught him to govern and direct Nature to his own benefit, and make her produce food for him when and where he pleased. From the moment when the first skin was used as a covering; when the first rude spear was formed to assist in the chase; when fire was first used to cook his food; when the first seed was sown, or shoot planted, a grand revolution was effected in Nature, a revolution which in all the previous ages of the earth’s history had had no parallel; for a being had arisen who was no longer necessarily subject to change with the changing universe, a being who was in some degree superior to Nature, inasmuch as he knew how to control and regulate 116 THE DEVELOPMENT OF LIFE. her action, and could keep himself in harmony with her, not by a change in body but by an advance in mind.” Physical science probably can never prove or disprove (in a sense of actual demonstration) the reality or non-reality of the existence of a soul either in or separate from the body. What our consciousness witnesses, reason and analogy must be brought into requisition if we would balance these proba- bilities. But the objection is urged that speculations concerning our spiritual natures cannot be considered scientific, because neither the positive nor the negative side of the question can be demonstrable ; yet these same objectors may speculate concerning the character or nature of the inhabitants of the planets, or concerning the nebular hypothesis, and call such speculations scientific. Hseckel (in chap. 22, "Hist, of Creation”) gives descrip- tions of manlike apes, and shows how similar they are to men in several respects. But what does this amount to upon the point under consideration until he can show psychological as well as physical similarities ? While he tries to show that man holds a certain relationship to the apes he as clearly states that man could not possibly have descended from any of the present races of apes, and that even the fossil remains of the immediate ancestors of man have not yet been dis- covered. He says (p. 277, vol. 2, "Hist, of Creation”) : "I must here also point out what in fact is self-evident, that not one of all the still living apes, and consequently not one of the so-called Manlike Apes, can be the progenitor of the Human Race. This opinion, in fact, has never been maintained by thought- ful adherents of the Theory of Descent, but it has been assigned to them by their thoughtless opponents. The Ape- EARLIEST MEN. 117 like progenitors of the Human Race are long since extinct. We may possibly still find their fossil bones in the tertiary rocks of southern Asia or Africa. In any case, they will, in the zoological system, have to be classed in the group of tail-less narrow-nosed Apes.” Even the very bones of the supposed ancestors, which might show the connecting link between man and the sup- posed ancestral race have never been found, and this is the very thing needed to furnish anything like proof of the correctness of his supposed line of descent. There is no geological evidence to show that any ape-like race of animals from which man could have descended existed prior to or since man’s first existence. There is evidence of man’s very early existence, but no definite evidence has been pro- duced that any ape-men, from which man might have de- scended, have existed during the whole records of time. How then can any one positively assert that man has de- scended from apes when it cannot be shown that ape-men existed before or since the earliest men? If such ape-men existed earlier than or even during the earliest periods of man’s existence, why should we not be able to find such a fossil-monkey or ape-man skull as well as fossil men’s skulls ? Some kinds of apes, or ape-like animals, existed very far back in the history of the earth. A. 11. Wallace, who in gen- eral supports Darwin’s Theory of Descent, writes (" Popu- lar Science Monthly” for Nov., 1876, p. 64) : "But so far back as the miocene deposits of Europe, we find the remains of apes allied to these various forms, and especially the gib- bons ; so that in all probability the special line of variation which led up to men branched off at a still earlier period.” This agrees with the statement of Darwin; but neither 118 THE DEVELOPMENT OE LIFE. Wallace nor Darwin intimates that he thinks man could pos- sibly have descended from any of the ape-like animals which existed in the miocene periods. Peschel (pp. 4, 5, "Races of Man”) says : "It is only a popular misapprehension, that, by the theory of transmuta- tion of species, man is supposed to be descended from one of the four highest species of apes. Neither Darwin nor any of his adherents ever asserted anything of the sort, but, on the contrary, they maintain that the ancestors of mankind branched off, in the first or earliest part of the tertiary period, from species of the Catarrhine group long since extinct.” But that the reader may see what Darwin says concern- ing the origin of man, I will quote extracts from Darwin, pp. 155-157, "Descent of Man.” On the birthplace and antiquity of man: "We are nat- urally led to inquire, where was the birthplace of man at that stage of descent when our progenitors diverged from the Catarrhine stock ? The fact that they belonged to this stock clearly shows that they inhabited the Old World, but not Australia nor any oceanic island, as we may infer from the laws of geographical distribution. In each great region of the world the living mammals are closely related to the extinct species of the same region. It is therefore probable that Africa was formerly inhabited by extinct apes closely allied to the gorilla and chimpanzee; and as these two species are now man’s nearest allies, it is somewhat more probable that our early progenitors lived on the African continent than elsewhere. But it is useless to speculate on this subject; for two or three anthropomorphous apes, one the Dryopithecus of Lartet, nearly as large as a man, and closely allied to Hylohates, existed in Europe during the DARWIN’S THEORY. 119 Miocene age ; and since so remote a period the earth has certainly undergone many great revolutions, and there has been ample time for migration on the largest scale.” " At the period and place, whenever and wherever it was, when man first lost his hairy covering, he probably in- habited a hot country; a circumstance favorable for the frugiferous diet on which, judging from analogy, he sub- sisted. We are far from knowing how long ago it was when man first diverged from the Catarrhine stock, but it may have occurred at an epoch as remote as the Eocene period; for that the higher apes had diverged from the lower apes as early as the Upper Miocene period is shown by the existence of the Dryopithecus.” " The great break in the organic chain between man and his nearest allies, which cannot be bridged over by any ex- tinct or living species, has often been advanced as a grave objection to the belief that man is descended from some lower form; but this objection will not appear of much weight to those who, from general reasons, believe in the general principle of evolution. Breaks often occur in all parts of the series, some being wide, sharp and defined, others less so in various degrees; as between the orang and its nearest allies, —between the Tarsius and the other Lemuri- dse, between the elephant, and in a more striking manner between the Ornithorhynchus or Echidna, and all other mam- mals. But these breaks depend merely on the number of related forms which have become extinct. At some future period, not very distant as measured by centuries, the civilized races of man will almost certainly exterminate, and replace, the savage races throughout the world. At the same time the anthropomorphous apes, as Prof. Schaaff- hausen has remarked, will no doubt be exterminated. The 120 THE DEVELOPMENT OF LIFE. break between man and his nearest allies will then be wider, for it will intervene between man in a more civilized state, as we may hope, even than the Caucasian, and some ape as low as a baboon, instead of as now between the negro or Australian and the gorilla.” "With respect to the absence of fossil remains, serving to connect man with his ape-like jwogenitors, no one will lay much stress on this fact who reads Sir C. Lyell’s discussion, where he shows that in all the vertebrate classes the dis- covery of fossil remains has been a very slow and fortuitous process. Nor should it be forgotten that those regions which are the most likely to afford remains connecting man with some extinct ape-like creature, have not as yet been searched by geologists.” Two remarks of Mr. Darwin in the above are especially worthy of attention. The first refers to the fact that serious breaks in the chain of evidence occur, and he says : " This objection will not appear of much weight to those who, from general reasons, believe in the general principle of evolu- tion.” Very true, for, when one becomes a strong believer in the general principles of any theory, it is not difficult for his imagination to supply all the necessary connections so as to make the whole system entirely consistent. If this imagina- tion could be considered in the light of evidence, then almost any popular theory or system might be rounded out into beautiful and symmetrical proportions. The second assertion is as follows : " With respect to the absence of fossil remains, serving to connect man with his ape-like progenitors, no one will lay much stress on this fact who reads Sir C. Lyell’s discussion, where he shows that in all the vertebrate classes the discovery of fossil remains has DARWIN’S THEORY. 121 been a very slow and fortuitous process.” Surely so; but why, in effect, assume that the evidence which is lacking would, if it could be discovered, be favorable to one theory, when perhaps by further searching for these missing links something might be discovered which would be the very reverse of favorable to the theory? It is very strange that while man-like apes nearly as large as a man existed in Europe during the Miocene age, and geological evidence should fully attest yet we do not find evidence that these apes were developed upward or became of a higher order during the immense time inter- vening between the Miocene and Pliocene ages. We may talk about the " imperfection of the geological record ” with much truth ; and the very fact that it is imperfect should make us modest in our assumptions concerning the full pur- port of its teachings. But, if man has been developed from an ape-like race, why should we not expect to find some direct evidence of the former existence of a race from which man might have descended as well as find the remains of man-like apes which lived long ages before we have any evidence that man existed? Or, in other words, why should we not find some definite geological evidence of the existence of ape-men before we assume as an undoubted fact that such a race ever existed ? It is also worthy of note that there is a difference of opinion between Darwin and Hasckel in regard to the birth- place of man. In his map Hgeckel places the supposed " Paradise ? ” in Lemuria, a locality now under the waters of the Indian Ocean. Darwin did not think the birthplace of men could have been on any " oceanic island,” but that "it is more probable that our progenitors lived on the African continent than elsewhere.” Darwin also thought 122 THE DEVELOPMENT OF LIFE. that "when man first lost his hairy covering he probably inhabited a hot country.” Several questions naturally arise from this last idea. First, how does any one know that man ever had a " hairy covering ” to lose ? Those who believe in Haeckel’s law of biogeny may conclude, from the fact that the human embryo for three or four months previous to birth is covered with woolly hair, that this is evidence that man’s ancestors once had a "hairy covering.” Haeckel says (vol. 2, pp. 206, 207, "Evolution of Man”) : "During the last three or four months before birth the human embryo is usually covered by a thick coating of delicate woolly hairs. This embryonic wool-covering is often lost during the last weeks of embryonic life, and, at any rate, soon after birth, when it is replaced by the thinner permanent hair covering.” " Occasionally the dark hair is retained for several weeks, or even months, after birth. This remarkable woolly cover- ing can only be explained as an inheritance from our pri- mordial long-haired ancestors, the Apes.” Surely this is a very clear explanation; but it lacks one important element, viz., proof of the truth of its inference, viz., that because the human embryo has a hairy covering which it generally loses before birth, therefore its primordial ancestors must have had a hairy covering, which their human descendants have lost. We must infer from the theory of natural selection that this loss of the original " hairy covering” (if it ever occurred) was of special advantage, for "the survival of the fittest,” or the most useful, is its motto. Possibly, in a very hot climate, loss of hair might be an advantage. But how about such advantage to those who inhabit a very cold climate? Would not this " hairy covering ” (which it is supposed they lost) SPIRITUAL NATURES. 123 be of immense advantage to men who inhabit a cold climate ? According to the foundation principles of " natural selection,” why should not a " hairy ” or fur-like covering now grow to protect men who need such a covering? Is "Nature blundering,” as Lewes expresses it? It is said that at the time of birth the young of apes are hairless, and that hair is an after-growth. Does not this very fact seem to indicate that the development of men and apes is in this respect in entirely different directions ? And may not this also indicate that this supposed hairy covering never existed on the ancestors of men ? But we will further consider the probability of the truth of this descent theory from diverse points of view. There are many things involved, and circumstances to be considered, besides those which relate to mere anatomy, morphology, or physiology. Before we assume that man is a mere animal, and nothing more, it will be well to explain how the belief that man has a spiritual nature has become so nearly uni- versal. Are these hundreds of millions of intelligent men who believe in a spiritual existence all deluded? Certainly they must be, if there is no spiritual existence. But before we assert dogmatically that all these millions are deluded would it not be well to exhibit something in the nature of proof that such is the case, rather than depend upon mere assertions ? Because a thousand men deny that there is any such thing as spiritual existence, when, from the very nature of the case, they cannot know whether it exists or not, these denials, no matter how positively made, are no evidence that spiritual existences may not be real entities. We must make certain allowances for almost universal convictions when reasoning concerning matters, which, from their very nature, must be 124 THE DEVELOPMENT OF LIFE. uncertain, or our doctrines will rest upon very insecure foundations. It is useless to repeat as applicable to this case the fact that the ancients were deceived when thinking that the earth stood still, and that the sun revolved around it. Conceptions and convictions of a spiritual nature are of a very dilferent kind. Desires and aspirations after continued existence are in the very constitutions of our natures. How came these, and how were these desires implanted? Desires for long life are one means of securing the continuance of life. When a healthy man craves food we naturally infer that such food is needed, and also that such craving is one means used by nature to indicate what is necessary for continued corporeal existence. When we assert the universal and harmonious application of nature’s laws shall we overlook these mental laws, and say that all mental desires are mere shadows, and without any reality behind them? Is life really a complete mockery ? The apparently inborn conceptions and convictions con- cerning man’s spiritual nature are not things which can be measured by a mathematical rule, or discovered by micro- scope or telescope, for spirit (if it exists) is invisible. Rules of reasoning which properly apply to purely material sub- stances may not be at all applicable to spiritual matters. The materialist denies that spiritual existences are real. How does he know this ? To assume that such is the fact is begging the question; for he knows not whether spiritual existences are real or unreal. I place the almost universal convictions of mankind (how- ever these convictions may have originated) against any dog- matic assertions that these convictions are all delusions; and, if they are not delusions, then materialistic doctrines THEORY OF ANALOGIES. 125 cannot be true, and man is a compound of physical and spiritual existence. Certain doctrines concerning man’s descent take for granted the assumption that man, outside of his physical or- ganization, can have no spiritual nature, and that intelligence and life cannot exist separate from a physical system ; but until some different kind of evidence is produced to show that man may not have a spiritual as well as a physical nature, any theory built upon such a negative assumption must, of necessity, rest upon uncertain foundations. One strange characteristic of many professedly scientific reasonings is, that while their authors treat those arguments which tend to induce a belief in man’s spiritual nature as entirely unscientific unless they are based upon clearly de- monstrable facts, yet, when they argue for their own favor- ite theories from positions which they have never shown to rest upon the rock-bed of truth, they proclaim themselves to be the champions of purely scientific methods. The theory that man descended from certain man-like apes is founded almost entirely upon analogies drawn from the production of plants and animals ; and so long as no bones of any race from which man could have sprung by direct descent have been found, why should we (upon the evidence offered) receive the theory as anything beyond an hypothesis which future investigation may or may not show to have truth for its foundation ? This theory of descent appears plausible, and also seems to accord with much which we know of the operations of nature’s laws. The chief objection which I now raise is against the positiveness with which the truth of the theory is asserted. There can be no doubt as to how the laws of evolution apply in the development of each human being 126 THE DEVELOPMENT OF LIFE. from a single cell; nor that the intellectual and moral facul- ties which so distinguish the man from the brute are, in some sense, the result of progressive development; and surely this line of development may be typical of man’s line of descent from an original one-celled ancestor, but the burden of proof is on the other side. Such bones as evolutionists state should belong to the im- mediate ancestors of man may yet be found; but when a theory so different from what has generally been supposed to be true is proposed, something besides analogies should be adduced before it should be placed in the region of proved facts. I am aware that the answer will be that nature always acts in a uniform way, and that, if the doctrine of evolution in regard to the lower animals is correct, it is only reasonable to conclude that the same laws must also apply to the devel- opment of man ; and if a lower order of animals can be de- veloped into a higher order, then man has probably been developed from a lower order. But if, while man is an animal he is also something more than animal, then, as before inti- mated, another factor comes in to modify our reasonings and analogies. But nature does not always work in the same direction of development. If she worked universally from the lower to a higher state of development, we might assume that there could not be any exceptions to the direction of developments. But there are very notable exceptions. The author of " Cosmic Philosophy,” himself a strong evolutionist, states, in a note to pp. 450, 451, vol. 1 : " Kowalewsky has discovered some wonderful likenesses between the embryonic development of the ascidian and that of the amphioxus, or lowest known vertebrate. Of all the ' missing links,’ the assumed absence of which is so persist- ABERRANT FORMS. 127 ently cited by the adherents of the dogma of fixity of species, the most important one would here appear to have been found; for it is a link which connects the complex and highly-evolved vertebrate with a very lowly form which passes its natural existence rooted plant-like to the soil, or rather to the sea-bottom. The ascidian cannot, indeed, be regarded as typifying the direct ancestors of the vertebrata. It is a curiously aberrant and degraded form, and its own progenitors had doubtless once ' seen better days.’ In its embryonic state it possesses a well-marked vertebral column, and it behaves in general very much as if it were going to grow to something like the amphioxus. But it afterwards falls considerably short of this mark. Already in early life its vertebras begin to become ' rudimentary ’ or evanescent; and when fully matured it stops swimming about after its prey, and, striking root in the submarine soil, remains there- after standing, with its broad pitcher-like mouth ever in readiness to suck down such organisms floating by as may serve for its nutriment. That vertebrae should be found in the embryo of such an animal is a most interesting and striking fact. It would seem to mark the ascidian as a ret- rograded off-shoot of those primitive forms on the way toward assuming the vertebrate structure, of which the more fortunate ones succeeded in leaving as their representa- tive the amphioxus.” This case shows a decided break in the general lines of development; and how many more as striking anomalies may exist we have not yet the means of knowing. The case of the ascidians used as a " missing link ” seems O to point in an exactly opposite direction from the general line of evolution. It much better accords with Plato’s theory of degenera- 128 THE DEVELOPMENT OF LIFE. tions running downward than with the theory that devel- opment is always upward. Its manner of development also seems inconsistent with the quite generally proclaimed theory that every vertebrate in its immature condition passes through conditions which pertain to all orders of the animal creation which are below it. Reasoning from analogy, may we not as justly assume (for all that has been shown to the contrary) that man may have a line of development from ancestral races as different from the general line as that which we find in the ascidians ? So long as the brain is the organ of the mind, man’s real position in nature and the probabilities relating to his line of descent cannot be fully and fairly balanced without keep- ing prominently in mind his mental structure and the testi- mony of his consciousness in regard to his position as a moral agent. But, we may be asked, if ideas of God, immortality, and moral responsibility are innate in man, why not class as beasts certain races of men which seem to have no ideas of a moral nature or a future life ? Upon the question whether such ignorant and degraded races do exist, authorities are divided. Some assert posi- tively that such races do exist; while others as positively assert, that, upon a better or more intimate acquaintance with such races, ideas of God and a future life are found to exist, and that the reason why certain travellers were unable to discover indications of such conception was a want of confidence of these savages in these travellers, but that when one becomes sufficiently intimate with them to acquire their confidence he plainly recognizes evidences of a belief in a Supreme Being or beings. But upon the supposition that races as degraded as above supposed do really exist, I IDEA OE IMMORTALITY. 129 can’t say to what depth of degradation certain races may have descended, nor from what height of former intellectual and spiritual development they may have fallen ; but surely the idea of immortality is implanted in the minds of a ma- jority of the people comprising the most intellectual races, and if we deny that this idea of immortality is a rational one, we must admit that these cultivated and fairly educated people have in some way imbibed more irrational notions concerning the origin and destiny of our being than such most ignorant and degraded races have; for, generally speaking, the most enlightened races do believe in man’s spiritual nature. While reflecting upon the strange positions taken by certain men of acknowledged scientific attainments, it has seemed tome that the majority of common-sense men, though less learned, are more likely to be right on the question of man’s destiny than the most learned speculators in the physical sciences can be, while leaving out of view the spirit- ual side of man’s nature. Either we must admit that the prevailing belief of the most intelligent and cultivated races concerning God and immortality is in its general features probably true, rather than the negations or absence of belief of the most igno- rant races; or we must admit that such study of things pertaining to the unknown conditions of existence as the most intelligent and enlightened races have been accustomed to give serves to mislead rather than give correct ideas of the real facts of the case. It is really curious to observe how extremes meet, —as ex- emplified in the case of men supposed to be so ignorant and degraded that they have no ideas of God or of immortal existence, and hence do not apprehend anything relating to 130 THE DEVELOPMENT OF LIFE. immortality, and certain learned men who reject doctrines implying the existence o*1 God and the immortality of the human soul. Whether one believes that these lowest races of men are right or wrong concerning a conscious immortal existence, in so far as they have any opinions upon the subject, the strange coincidence still exists between those supposed to be so ignorant as to have no conceptions of a Supreme Intelligence, and atheistic writers, who conceive that an Omniscient and Supreme Intelligence cannot be in existence. It would appear to be strange if the most degraded and ignorant races and a few of the learned men should be right, while the majority of learned men and the great body of men comprising the fairly intelligent common people should be in the wrong on this question. But it cannot be true that study tends to mislead and draw away from rational truth, if the student gives proper consideration to all facts which ought to be considered. The reason why many become atheistic through study is doubtless because they entirely disregard facts pertaining to the " spiritual side of man’s nature,” and hence while looking at one side they take only partial views of the whole field. What then can we expect, but that they should have one-sided and contracted views ? This, it seems to me is just what we do find. Upon this point the sceptic Hume (whom I suppose, no one will accuse of lack of intelligence) says in his "Essays,” p. 551 : " Though the stupidity of men, barbarous and uninstructed, be so great that they may not see a Sovereign Author in the more obvious works of nature to which they are so much familiarized; yet it scarcely seems possible that any one of good understanding should reject that idea, when once it is suggested to him.” BELIEF IN OVERRULING POWER. 131 Again, he says, p. 552, ibid.: " The universal propensity to believe in invisible, intelligent power, if not an original instinct, being at least a general attendant of human nature, may be considered as a kind of mark or stamp, which the Divine Workman has set upon his work ; and nothing surely can more dignify mankind than to be thus selected from all other pai'ts of the creation, and to bear the image or impres- sion of the Creator.” " What a noble privilege is it of human reason to attain the knowledge of the Supreme Being, and, from the visible works of nature, be enabled to infer so sublime a principle as its Supreme Creator ! ” " Look out for a people entirely destitute of religion; if you find them at all, be assured that they are but few degrees removed from brutes.” Darwin takes a somewhat different view, as follows, p. 12G, "Descent of Man ” : " The ennobling belief in God is not universal with man ; and the belief in spiritual agencies naturally follows from other mental powers. The moral sense perhaps affords the best and highest distinction between man and the lower animals.” I will now introduce a witness whom even Haeckel will not try to discredit, viz., Mr. T. H. Huxley. Mr. Huxley has with great ability discussed questions pertaining to the origin of species, and candidly states that positive proof that one species of animals has changed into another has not yet been adduced. On p. 141, "Origin of Species,” writing of changes of species ; Mr. Huxley says : "For you see, if you have not done that you have not strictly fulfilled all the conditions of the problem; you have not shown that you can produce by the cause assumed all the phenomena which you have in nature. Here are the phenomena of hybridism staring you in the 132 THE DEVELOPMENT OF LIFE. face, and you cannot say, 'I can, by selective modification, produce these same results.’ Now it is admitted on all hands that, at present, so far as experiments have gone, it has not been found possible to produce this complete physiological divergence by selective breeding. I stated this very clearly before, and I now refer to the point, because, if it could be proved not only that this has not been done, but that it cannot be done, if it could be demonstrated that it is im- possible to breed selectively, from any stock, a form which shall not breed with another produced from the same stock; and if we were shown that this must be the necessary and inevitable result of all experiments, I hold that Mr. Darwin’s hypothesis would be utterly shattered. But has this been done ? Or what is really the state of the case ? It is simply that, so far as we have gone yet with our breeding, we have not produced from a common stock two breeds which are not more or less fertile with one another.” Also Huxley writes ("Man’s Place in Nature,” p. 127) : " But, for all this, our acceptance of the Darwinian hypothesis must be provisional so long as one link in the chain of evidence is wanting; and so long as all the animals and plants certainly produced by selective breeding from a common stock are fertile, and their progeny are fertile with one another, that link will be wanting; for, so long, selective breeding will not be proved to be competent to do all that is required of it to produce natural species.” If all the difficulties which Huxley here states have so far prevented the truth of the Darwinian theory concerning changes of species from being demonstrated were removed, even then more evidence would be required before the Darwinian hypothesis of the descent of man could be con- sidered proved. For if, by selective breeding from a common PRODUCTION OF NEW VARIETIES. 133 stock, races should be produced so different that they are not fertile between themselves, that would simply show that natural selection may account for differences of races of animals ; but that would not show that it can account for the difference between men and animals. If we could by extra care in selective breeding produce such a race as Mr. Huxley supposes might be produced, it would simply show what could be done under the intelligent guidance of man among animals ; but it would by no means show that such a race ever did or probably ever would be produced through the guidance of mere instinct, or through the dim intelligence of the brutes. We have no reason for supposing that the general species of animals have had any- thing more than brute intelligence or instinct to guide them towards the almost numberless variations of development which we find. But if it has not been shown that by the greatest care in selective breeding among animals, under the intelligent guidance of men, the required differences or transmutations of species can be obtained, how long would it take to pro- duce such results by chance-breeding alone, or by natural selection, without intelligent guidance? And if, among animals quite similar in their general structure and habits, men have not been able to produce new species by careful selected breeding, how long wTould it take, through blind chance, to develop men from apes? We must, however, confess that the statement of Agassiz, that each separate existing species represents a separate creative thought of God, does not now find a favorable re- O ' sponse from a majority of naturalists. If Agassiz were still living, and were again to write upon the same subject, he probably would considerably modify 134 THE DEVELOPMENT OF LIFE. some of his former statements. But we must not be hasty in concluding that he was greatly in error in his statement above quoted; for the history of past scientific theories in relation to evolution, and creation, including the origin of life, is sufficient evidence of the utter unreliability of theories which may carry all before them in the scientific world for even a century. Take, for instance, the case of the evolution theory, based upon the idea that every human being that ever lived or ever will live was in the germ in the ovary of Mother Eve, and also the other contrary theory, that all life comes from the male or sperm cell, and that the germs of all subsequent human life were in the loins of Adam. The first theory held its ground against all scientific comers for about a cen- tury ; and the second had powerful defenders for about another century. These two theories were disputed about by most intelligent and most learned men, who were pitted against each other in argument for nearly a century, and why ? Because there were no naturalists or biologists of suffi- cient learning and ability to convince the world that either of these theories was incorrect, and remove the weight of error that inhered in both. I will now give a short history of these theories, partly taken from the more extended history by Haeckel. The theory of encasement, or that of the ovulists, viz., that the germs of all subsequent human existences were in the ovaries of Eve, held it§ ground and was generally ac- cepted till 1690. Then the theory of the animalculists, or that all came from the loins of Adam, took its turn, and the two entered into a contest for supremacy. Leeuwenhoek, in 1690, started the spermatozoid theory. OYULIST THEORY. And from that came the doctrine that the germs of every human being which has ever existed or ever will exist to the very latest time were in the loins of Adam, and that each spermatozoon had in its microscopic proportions en- wrapped the germs of an almost infinite number of human beings who were to succeed in all generations. From Hebrews, 7 ; 10, it is evident that a similar belief obtained in the time of St. Paul, for he there represents Levi, the great- grandson of Abraham, as paying tithes to Melchisedec while he was in the loins of Abraham. Abraham's meeting with Melchisedec was several hundred years before the Levitical priesthood was established. These two theories of evolution, the one of the male running back to Adam, and the other of the female running back to Eve, had vigorous defenders, and these discussions were continued through the period allotted to several generations. Among the celebrated defenders of the ovulist theory wei’e Leibnitz, Bonnet, and Haller. On the other side were Leeuwenhoek, the originator, and afterwards Spalanzani and other very learned men. Haller contended that there was no such thing as any new creation, and that the germs not only of life but the germs of every member of the body existed from the beginning, and that every form of life is but the unfolding of what existed from the very first creation. This is evolution in earnest; and I may say that Haller’s disciples still survive, for I have heard the same, or nearly the same, statement made by a well-educated gentleman within a short time. Haller went so far as to calculate the number of human beings in the ovaries of Mother Eve, and (according to Haeckel’s statement) this number was " 200,000,000,000,” supposing that the world would stand six thousand years. 136 THE DEVELOPMENT OF LIFE. What was to become of the world after that time we are not informed. The celebrated Leibnitz went so far as to claim that the souls of men were in monads or the primary ele- ments of matter. According to him the monads were "without extent, incorruptible, and so constituted that their whole future is contained in their beginning.” "In every monad might be read the world’s history from beginning to end; each of them being a kind of Deity.” " God is the absolute, original monad, from which all the rest are gen- erated ; the primitive and necessary substance, in which the detail of changes exists emanantly.” (" Am. Gyc.,” p. 325, vol. 10.) Either the ovulist or the animalculist theory held sway with the majority of men, both learned and unlearned, until after the beginning of the nineteenth century. From 1690 to 1812 one or the other theory held the uppermost position among scientific men; and for about two hundred years one or the other of these theories held especial promi- nence in scientific discussions. The supporters of present evolutionary theories are not superior in intellectual vigor to Leibnitz, Haller, and others, who, a hundred or more years ago, were fully satisfied that they were correct in the views which they promulgated con- cerning the origin and development of life. So also the doctrine of cataclysms, which Cuvier believed, and which hosts of other great men believed, held almost universal acceptance until Lyell showed that the building of the earth’s different strata might have been accomplished through long ages, quietly, and under the regular operations of nature. The fact that a theory may apparently explain certain heretofore unexplained phenomena by no means shows that “THE WAYS OF MONKEYS.” 137 some other theory may not explain these phenomena much better. * While it is true that men and apes are wonderfully similar in their affectionate attachments, and the grief of the ape mother on being deprived of her children by death is much like that of the human mother, and the disposition to curiously examine and investigate concerning all objects within their reach is much alike in men and apes, yet some- thing more than proof of similarities of disposition and phys- ical structure is needed to show that one of these species could ever have descended from the other. The assent of a majority of the most learned naturalists and biologists for a whole generation is not enough, in a matter like the origin of the human race (concerning which unimpeachable evidence has not been obtained from science), to reasonably induce a fully settled belief in theories which have not, and probably cannot, at present, be demonstrated. In "Popular Science Monthly” for June, 1885, there is a very able article on " The Ways of Monkeys,” from the pen of the noted German naturalist, Alfred E. Brehm. Brehm had extensive and uncommon opportunities for studying the nature and habits of the apes, both in captivity and in the wilds where they live, and he closes his article as follows : " Was the ancestor of the human race a monkey ? That is the vexed question which still raises so much dust. " There is no doubt that man is not more and not less than the chief creature in the animal kingdom, and that the monkeys are his immediate neighbors; but I cannot see why this fact should logically involve the assumption that our great-great-uncles were gambolling in Paradise in the shape of apes. The doctrine of gradual evolution may seem trust- worthy in the highest degree, and beautiful from the scientific 138 THE DEVELOPMENT OF LIFE. stand-point, but it is based upon a simple hypothesis ; and a hypothesis is not a proof; and here I wish not to be misun- derstood. Even if the physical and intellectual development and perfection of humanity throughout the succession of thou- sands of centuries is a fact, there is no authority for the in- ference that, eo ipso, a monkey-nest was the cradle of man- kind. " Darwin’s treatise on the variation of species gave rise to the ardent controversy of our days. Darwin used the wrong word. It is not 'species’ he ought to have said, but ' varieties ; ’ for species never interbreed with each other. Man and monkey, though belonging to the same group, represent two distinct species. There is, consequently, a simple and irrefragable natural law refuting peremptorily the thesis of the enthusiastic propugnators of the pedigree root- ing somewhere amid a grinning tribe gambolling in the wild forests of Asia or Africa. The criterion that the human race has large, round hands, and blunt, canine teeth would be sufficient of itself to establish the truth that no monkey-blood is pulsating in our veins. But there are more distinctive features. Men have strong, well-shaped legs, walk con- stantly in an erect posture, and enjoy the faculty of speech. " The monkeys rank near humanity in the general organ- ization of the world ; they show in many instances much like- ness with mankind, physically as well as intellectually. Bui a further concession would be a denial of positive natural laws. Nay; old Adam was not a monkey, not a baboon, not even a chimpanzee ! ” This declaration of Dr. Brehm will be considered scientific scepticism. But do we not sadly need more of this kind of scepticism? It is curious to observe, however, that those most impatient with this kind of scepticism are accustomed HiECKEL AND HUXLEY. 139 to compliment other kinds of scepticism with the name of philosophical inquiry. In one respect Eheckel differs widely from Mr. Huxley. With Huxley scientific scepticism is a duty. He says, in substance, "compel assent if you can,” or compel me to re- ceive the proposed hypothesis if you can, and I will receive it. But Hreckel says of Darwin’s Theory of Descent ("Hist, of Creation,” p. 28) : "In any case we are in duty bound to accept this theory till a better one be found which will under- take to explain the same amount of facts in an equally simple manner. Until now we have been in utter want of such a theory.” And, further, when he wishes to show that there is no necessity for supposing that there was an original Crea- tor, he says : "It cannot fail to appear, in the light of the Doctrine of Descent, no longer as the ingeniously designed work of a Creator building up according to a definite pur- pose, but as the necessary consequence of active causes which are inherent in the chemical combination of matter itself, and in its physical properties.” (p. 27, "Hist, of Creation.”) How has the doctor or any one else learned that these " active causes which are inherent in the chemical combina- tion of matter itself” are naturally " inherent ? ” How does he know that these " inherent ” qualities are not the agencies of the very Creator he would so summarily dispense Avithr It is easy for most men to believe what they really wish to believe. 140 THE DEVELOPMENT OF LIFE. CHAPTER YI. THE DEVELOPMENT OF LIFE. The question whether there is a designing intelligence behind the phenomena which we observe in nature will con- tinually meet us. Does the material universe (as well as the entire list of animals) exhibit itself so unskilfully and clumsily consti- tuted that its construction is disgraceful to or unworthy of a designing intelligence ? Is it because all nature is so o o o poorly arranged for intended purposes that a certain class of writers must attribute its existence to blind, unconscious, purposeless forces, or to necessity? Because we can see no evidence of design in certain things which exist, shall we assume that the many apparent evidences of design are all deceptive ? This raises questions concerning the connection between mind and matter, and concerning their dependence on or independence of each other : whether mind is dependent upon matter for its existence, or whether mind existed prior to or can exist independent of matter. Is it reasonable to suppose that the mind, which moulds matter according to its purposes, which uses matter as it wills, to which all matter is subject, can be itself subject to material laws, and itself the child of matter? Like begets like: can intelligence spring from a source which is not itself intelligent, or from something having a less intellectual nature than an intelligent being? Can in- MIND AND MATTER. 141 telligence be evolved from mere matter, which it is supposed has no intelligence? What is the real origin of thought? How did it first have an existence? Whence came the consciousness of our own existence ? Is the idea that thought can have been evolved or derived from an unthinking source a thinkable one ? Must we not conclude that there is a self-existent intelli- gent source of thought, unless we are prepared to confess that an effect has been produced without any adequate cause ? Can the mind, through which matter is made subservient to the desires of man, be itself derived from matter? Is a machine the producer of the mind which first conceives the idea of its construction ? Which precedes in the order of time, the machine, or the plan of the machine, in the mind of its inventor? Carry this idea through the whole realm of nature, even to the construction of the worlds which consti- tute the universe, and you will find that the analogy holds good. Sidney Billing says (p. 8, "Scientific Materialism”): " When the symbol photographed in the eye receives transla- tion it becomes our reality. How then can it be said the major (mind) has its origin in the minor? (matter) ; logi- cally we know all majors are composed of minors, but this can be said only of related things; pile as we may atom on atom we should never elicit mind; pile idea on idea and a wisdom would be attainable approaching the precincts of infinitude. Perceptive knowledge is built up of the symbols of things, not of things. How then can we say that the symbolical expression of that we term matter, objective forms, creates the subjecting intellect?” But I hear it repeated, that living and active forces inhere 142 THE DEVELOPMENT OF LIFE. in the very atoms of which the universe itself consists. Well, how did these active forces get into these atoms ? Who placed them there ? Did these forces make themselves ? Were they self-originating? Were they self-existent? If we predicate self-existence of matter, by what just reasoning can we deny self-existence to intelligence? Agassiz went to the very bottom of this subject, and acknowledged a first and ultimate cause; but Eheckel says, " All our knowledge is limited, and we can never apprehend the first causes of any phenomena.” While it is not likely that avc shall ever " apprehend ” or comprehend " first causes,” we know that there must have been a first cause, or "cause of causes,” or else an endless chain of causes. Agassiz refers all to a great first cause. Haeckel does not inquire about the first cause, but only in regard to the action of secondary causes. He does not seem to consider that these secondary causes must be dependent for their action on a great first cause. Ido not think Darwin ever denied the creative acts of a great first cause. Darwin started in his calculation and theories with life already in existence, and reasoned from what has succeeded the first creation. Darwin closed his enlarged and corrected sixth edition of the " Origin of Species ” with these words : " There is grandeur in this view of life, with its several powers, having been originally breathed by the Creator into a few forms or into one, and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being evolved.” Here Darwin 7 O acknowledges that the Creator originally breathed life into " a few forms or into one.” But if you ask the atheistic class how life or living beings CREATIONS. 143 came to exist on the earth, when it is evident from the teachings of geology that there was once a time when no life existed on the earth, the answer readily comes, "By sponta- neous generation.” But if this " spontaneous ” theory is true, what has been spontaneously generated? Bits or particles of protoplasm? How large were these particles of the first living matter? If molecules of livingmatter can be spontaneously generated, why may not larger living particles also be generated spontaneously ? How do we know that what we call " spontaneous ” is not something ordered by a divine creative power ? And if this " spontaneous ” or creative power could bring into being from non-being molecules of living matter, why could not this force or power also bring into being larger masses of proto- plasm, or even living animals? And if animals of the very simplest structure, why not those of more complex structure, or even animals of the higher orders ? Where shall we stop the possibilities of this power, whether we call it creator, living force, or by any other name? Some power has brought the living from the non-living. Then by what philosophical consistency can we ridicule the idea of special creations, even if we cannot prove that there ever has been any special creation? We have been accustomed to see nature work in certain ways, and we have never observed it to work in any dif- ferent way, and hence we infer that it cannot work in any other way. But this is by no means the necessary conclusion ; and yet from the very constitution of our minds we are in- clined to draw such an inference. If we had never seen anything spring up and grow as certain kinds of vegetation do, and one should attempt to explain how such a thing 144 THE DEVELOPMENT OF LIFE. might exist, we might doubt its existence. His statement might seem to us as wonderful and inexplicable as some other events which have been deemed miraculous, and this simply because it was so different from anything we had ever seen or contemplated. So we see living things produced in certain ways. We know that animals and plants come into existence in certain ways, and we infer that they have always come into existence in the same way, and we also infer that they cannot be brought into existence in any other way; but this last inference is by no means a necessary one. The fact that we have never known a certain thing to exist furnishes no proof that such a thing has not existed, or may not exist. Thus both spontaneous generation and the " Immaculate Conception ” have been supposed to exist, and probably as many believe that the " Immaculate Con- ception ” actually took place as believe that " spontaneous generation ” ever took place ; and the believers in the " Im- maculate Conception ” are not inferior intellectually to the believers in r' spontaneous generation ; ” yet nearly all be- lievers in spontaneous generation ridicule the doctrine of the " Immaculate Conception.” But whether either spontane- ous generation or the " Immaculate Conception ” ever ex- isted may be incapable of proof or disproof through any scientific demonstrations. Because there is a general similarity of plan in the build- ing up of all animals, trees, and vegetables, and all other living things, the inference is drawn that all these forms have descended from some common ancestor. It is just here that the development and the former creative theories branch off from each other. Their point of contact is like the entering part of a wedge, and from that point they diverge. Evolutionists contend that it is easier and more philosophical SIMILARITIES. 145 to believe that this striking resemblance in all animal ex- istences is caused by development through the laws of de- scent from a common ancestor than to believe it comes from separate creative acts. But this similarity does not stop on the earth, or with life on the earth either in the animal or vegetable forms; but the same proportions and similarities run through the plan- etary systems ; and we might ask, From what ancestors did the planetary system descend? How about the solar sys- tem ? How comes it that there are such striking proportions between the planetary distances and the groups of leaves on the trees and the flowers in the garden or on the hill-side? (See Agassiz on "Classification,” p. 193.) Why should pro- portional numbers of the various orders of plants so corre- spond to the distances of the planets? This question, if answered, might carry out the develop- ment hypothesis to its philosophical or logical conclusions. But, further, how comes it that the solar system appears to be but a picture, or type of the universe, which certain astronomers have supposed revolves around a great central sun at a period numbering millions of years ? It can easily be conceived how the moon may, in a figurative manner, be called a child of the earth, for perhaps fifty millions of years ago (more or less) the moon may have been thrown off from the surface of the earth when the earth’s revolutions were so rapid as to overcome the attrac- tive forces. It is not probable that in like manner the planets can be called children of the sun, for it appears probable that the earth became consolidated from cosmic vapor earlier in time than the sun. Doubtless all suns, stars, and planets are governed by 146 THE DEVELOPMENT OE LIFE. fixed and immutable laws, and their shapes, being nearly globular, are substantially alike. And further, perhaps their material substances or chemical combinations may be sub- stantially alike. This is all within the range of probability. By " immutable laws ” I mean the observed antecedence and sequence of events, and their connection with and de- pendence upon each other. When we assume this immu- tability we do not know that there may not be thousands of antecedents and consequents, the nature of which we cannot comprehend. But what reflective and unbiassed man can see all this immense system, commencing at the smallest particle which can be seen with the microscope, and trace it up through all sizes and types, and find the same beautiful order run- ning from the smallest animalcule to the largest planets and suns, and then see no Supreme Architect for all these in- finite variations ? I am aware that those who do not believe that mind or spirit can have a real existence separate from matter, but who assume that mind is a mere process or a variation of some form of life, will not consider this mode of treatment scientific. But before such become too positive in their statements concerning the nature of the original mind, in- telligence, or spiritual existence, it will be well for them to give us something besides speculative assumptions upon which they build their theories. Which is the more dignified and the more reasonable? to believe in the existence of an Almighty Intelligent Power, who created, and still sustains the universe by his constant care, or to believe that dead, soulless, mindless matter, without any purpose, and through " unconscious causes,” brought into existence the sun, planets, and stars through space ARRANGEMENT OF THE UNIVERSE. 147 illimitable, together with all the intelligence of rational creatures ? In regard to the beautiful and perfect arrangement of the heavenly bodies, Robert Chambers, the author of " Yestiges of the Creation,” says (pp. 17, 18, Harper’s edition) : " Proportions of numbers and geometrical figures rest at the bottom of the whole. These considerations, when the mind is thoroughly prepared for them, tend to raise our ideas with respect to the character of physical laws, even though we do not go a single step further in the investigation; but it is impossible for an intelligent mind to stop there. We advance from law to law, and ask, What is that? Whence have come all these beautiful regulations? Here science leaves us, but only to conclude, from other grounds, that there is a first cause, to which all others are secondary and ministrative, a primitive, almighty will, of which these laws are merely the mandates. That great Being, who shall say where is his dwelling-place, or what his history? Man pauses breathless at the contemplation of a subject so much above his finite faculties, and can only wonder and adore.” Opinions of scientific men on these points are no better than those of so many farmers. Reason and common-sense must be our guide here (if we reject the idea of revelation), for all know that certain facts exist which man has never ex- plained. The lines that somebody once wrote about two kinds of fools are applicable here, viz. : "The simple fool is he who knows that he does not know; the compound fool is he who does not know that he does not know.” Possibly, if the advocates of various conflicting theories concerning the origin of things could better understand the positions of their opponents, there might not appear to be a very wide divergence at the real foundations of their 148 THE DEVELOPMENT OF LIFE. beliefs; but these differences of opinion now seem to be radical at the very foundation. But I may remark that all men believe there is an invisible force or power acting through nature; and the very germ of the whole inquiry on this point lies in this, viz. ; is this invisible power an intelli- gent one? Does this intelligent power (if it exists) exist separate from and independent of matter? or, if it exists and inheres in matter now, did it exist prior to matter, and organize matter into bodies as they now exist? or, if matter in its elements is eternal, and spirit eternal also, did this intelligence or power create the forces that drew these ele- ments of matter together into worlds and systems of worlds ? Are what we call the laws of nature simply unconscious forces ? or are they manifestations of an intelligent being by whose power these forces were created, and by whose will they are kept in unerring operation? If one admits that these forces are under intelligent or purposive direction, he admits the most essential part of the theistic argument; for if this intelligent power exists and acts, it matters little (from a scientific stand-point) by what name we call it, whether we call it God, Allah, Jehovah, or by some other name. But in a religious sense it makes a vast difference, for no one would consider a simple power of nature worthy of adoration and worship. But if this power is like or akin to what we term personal, and of the highest intelligence, it is in the highest degree proper that he should be revered and worshipped; for by this power all life, all good must be held. All our well-being, not only now but for the whole of our existence (be that longer or shorter), and whether the soul survives the body or not, is in his keeping. If the soul does not survive the dissolution of the body, then all the happiness we can ever experience will be in this world, INTELLIGENCE AND SYMPATHY. 149 and even that is of the greatest moment; for it is the greatest boon we can have. If this intelligence exists and is, or is like a personal being, it is certainly reasonable to hope that he may have sympathies and affections. Every intelligent creature of which we have any knowledge has sympathy ; and why should we imagine that the very highest intelligence should be devoid of sympathy? and if not devoid of sympathy, why, in a scientific sense, is it not reasonable to strive to be worthy of this sympathy, and why should we not also hope that we may do something towards deepening this sympathy in our behalf? If we believe as the major part of the greatest thinkers in the most enlightened nations of the earth have believed in regard to the soul’s im- mortality, or as Socrates and his illustrious disciple Plato taught, or as, later, Jesus taught, " That man is a being des- tined for eternity,” then this question concerning immortal existence must be a very important one ; and if the belief in its reality is founded on fact then this idea deepens into one of supreme importance. In the presence of this question all others dwindle into comparative insignificance. But if we conclude that we cannot demonstrate the cor- rectness or incorrectness of the existence of an almighty and benevolent Intelligence, and a conscious immortal existence, still this is no trifling question, for it lies at the very root of our most important interests. It would seem as if all might be agreed here. lam aware that it is impossible for human thought to grasp the terms Infinity, Omnipotence, Omni- science, and the like, and that in attempting to apply human words to describe The Ineffable, or one infinitely above all our conceptions, we can make but a sorry approach towards such expressions as we would like to make. Being ourselves of limited intellectual powers, we cannot fathom the myste- 150 THE DEVELOPMENT OF LIFE. rious essence of a power infinitely above our highest intel- lectual conceptions ; but in speaking of Him we are obliged to use human language, and are also confined within the limits of human thought; hence all our descriptions and con- ceptions of the Divine One must of necessity be very imper- fect. But though we cannot comprehend the idea of infinity or eternity, we are not debarred from reasoning■ concerning them. Considerable misunderstanding has arisen concerning what is meant by the term " creative theory.” Many understand by this something like Milton’s poetical descriptions, or that each separate species of animals was originally created with characteristics essentially like those they now possess. But it by no means follows that another theory may not properly claim the name creative. Any theory which necessitates the existence of an original creator is a creative theory. The theory which is distinctively in opposition to the " spontaneous generation ” theory of life is properly called creative. The doctrines of evolution as taught by Darwin necessitate the existence of creative intelligence to start life into being, as Darwin himself intimates in the closing paragraph of his "Origin of Species,” and any theory which calls for this creative beginning is properly styled a creative one. It is true that Huxley demolished a certain theory which he called creative, viz., "The Miltonic Theory; ” but even Huxley was obliged to admit that some time during past ages the present laws of nature might not have acted in the invariable order in which they now act. Even if only one form or type of life was originally created, and all succeeding types or forms however varied have been evolved from that original form, creative intelligence is none the less needed to start that original form of life. The DESIGNING POWER. 151 intelligent being or power who set in motion causes which would result in such a surprising variety of living creatures through descent from one single form (if life has thus been evolved) must be indeed of the very highest order of in- telligence. If this being set in order laws through which the world both animate and inanimate would run on without any disturbance of its natural relations for millions of years without intelligent supervision, that being must, if possible, be of even a higher order of intelligence than one that should originate a system that would run regularly with intelligent supervision. What I claim, however, is that this immense machinery of life, as well as of inorganic nature, which, we say, is governed by the laws of nature, could not originate itself; but it must have been originated or set in motion by a power, force, or being having an infinitely high order of intelligence. Nothing less than this could plan and execute all that is involved in the continued preservation of life, as well as keep in regular orbits the planetary worlds. If the Darwinian theory is correct, and all animals and plants have been, through countless ages, developed from a "few original forms,” then this very system of develop- ment, so constant and regular in its operations, necessitates the existence of an Omnipotent and Omniscient Power to or- dain, guide, regulate and execute these complicated natural laws so that, ever acting, they never clash or fail in their unvarying regularity. Much ingenuity and a considerable amount of learning have been employed to show that the all-pervading power, "which every reflecting person must see exists, and which governs all the operations of nature, is not an intelligent being, but only a blind force, or simple necessity, operating 152 THE DEVELOPMENT OF LIFE. in a manner purely mechanical. While others admit that there must have been an intelligent power to originate natural laws, they contend that, when once instituted, these laws run on without need of any intelligent supervision. Dr. Hitchcock, on pp. 294, 295, " Religion and Geology,” writes concerning the position of the advocates of this last theory as follows : "I know, indeed, that La Place, and some other advocates of this latter hypothesis, do not admit any necessity for a Deity even to originate matter or its laws; and to prove this was the object of the nebular hypothesis. But how evident that in this he signally failed ! For even though he could show how nebulous matter, placed in a certain position, and having a revolution, might be separated into sun and planets by merely mechanical laws, yet where, save in an infinite Deity, lie the power and the wisdom to originate that matter, and to bring it into such a condition, that, by blind laws alone, it would produce such a universe so harmonious, so varied, so nicely adjusted in its parts and relations, as the one we inhabit? Especially, how does this hypothesis show in what manner these worlds could be peopled by countless myriads of organic natures, most exquisitely contrived, and fitted to their condition ? The atheist may say that matter is eternal. But if so, what but an infinite mind could in time begin the work of organic creation ? If the matter ex- isted for eternal ages without being brought into order, and into organic structure, why did it not continue in the same state forever? Does the atheist say, All is the result of laws inherent in matter? But how could those laws remain dormant through all past eternity, that is, through a period literally infinite, and then at length be aroused into in- tense action? Besides, to impute the present wise arrange- BUDDHIST THEORIES. 153 ments and organic creations of the world to law is to endow that law with all the attributes with which the theist invests the Deity. Nothing short of intelligence, and wisdom, and benevolence, and power, infinitely above what man possesses will account for the present world. If there is, then, a power inherent in matter adequate to the production of such effects, that power must be the same as the Deity ; and, therefore, it is truly the Deity, by whatever name we call it.” The idea that blind, unconscious forces are the ruling powers of the world well agrees with the leading tenets of Buddhism. The Buddhist religion does not mention any God as the creator and ruler of the world. Neither do they have any idea of the moral quality of any act being at all changed or modified because it is according to the will of any God. All the idea of morality they have is simply a fitness of things, and the consequences of acts follow not as we should suppose, with invariable sequence, but often by a sort of fitful irregularity. But their doctrine of transmigra- tion of souls gives them the chance to account for all the evils which befall any one here; for the sufferings which one has here are the result of acts which he may have committed in a previous state of existence when he might have been an elephant, or, perhaps, a tiger. This well accords with the evolutionary theory of inherited tendencies, characters, or traits. Arnold, in " Light of Asia,” p. 96, writes : “ That once and wheresoe’er, and whence begun Life runs its rounds of living, climbing up Erom mote, and gnat, and worm, reptile and fish, Bird and shagged beast, man, demon, deva, God, To clod and mote again; so are we kin To all that is.” 154 THE DEVELOPMENT OF LIFE. Of course, with the absence of a belief in an eternal self- existent Deity, the idea of immortality must, of necessity, be absent. But according to Buddhist teachings, the least time which the bad will have to stay in one of their one hundred and thirty-six hells is ten millions of years, and the least time in their heaven is ten billions of years; yet this is not immortality, for at the end of these immense cycles death comes, and then the unfortunate must be born again, into what shape, whether animal, vegetable, or human, no one previously knows. Buddha arrived at such a state of knowledge that he could remember what he did when he was in the shape of several different animals before he was born a man, so the sacred books inform us,—and that, to him, must amount to a demonstration of his line of descent. Speculations concerning the origin of the universe, as well as of organic life, are no new thing. Plato noticed the arrangements and motions of the planets and those of animated nature; for, according to Bain, he considered the Cosmos, "in its totality a vast and com- prehensive animated being; the model for it is the Idea of Animal the Self-Animal. As created, the Kosmos is a scheme of rotatory spheres, and has both a Soul and a Body. The Soul, rooted at the centre, and pervading the whole, is self-moving, and the cause of movement in the Kosmical body.” ("Mind and Body,” p. 147.) This universal Soul typified the laws of attraction or gravitation. Plato likewise believed in degrees of intelligence and station, and in a line of reasoning like that of the present evolution- ists, only he starts from a different stand-point. He starts with the gods as the highest intelligence, and then runs down in a series of degeneracies through men to the animals. He makes the seat of the immortal soul in the brain; but PLATO 155 this soul has to contend with two other principles which sadly hamper it in its harmonious acts and desires. He also believed in self-existent ideas, or intelligence anterior to the formation of the world; but it would seem that Plato believed in the eternal existence of matter in its simple con- stituents, a scientific idea which many modern philoso- phers still cling to. It is evident, however, that Plato believed in one original great First Cause, or one eternal, intelligent, self-existing Being, who was the organizer of all things; but that, sub- sequently, other inferior deities presided over the destinies of the Cosmos. These inferior deities may well represent the secondary causes, or natural laws. In regard to the creation, or, rather, formation of worlds, the theory of La Place has been widely received, and may be as philosophical as any other which has been proposed. Summarized by Dr. Hitchcock, it is as follows, p. 287 : "He (La Place) supposes that, originally, the whole solar system constituted only one vast mass of nebulous matter, being expanded into the thinnest vapor and gas by heat, and more than filling the space at present occupied by the planets. This vapor he still further supposes had a revolution from west to east on an axis. As the heat diminished by radiation, the nebulous matter must condense, and consequently the velocity of rotation must increase, and an exterior zone of vapor might be detached, since the central attraction might not be able to overcome the increased centrifugal force. This ring of vapor might sometimes retain its original form, as in the case of Saturn’s ring; but the tendency would be, in general, to divide into several masses, which, by coalescing again, would form a single 156 THE DEVELOPMENT OF LIFE. mass, having a revolution about the sun, and on its axis. This would constitute a planet in a state of vapor; and by the detachment of successive rings might all the planets be produced. As they went on contracting, by the same law, satellites might be formed to each ; and the ultimate result would be solid planets and satellites, revolving around the sun in nearly the same plane, and in the same direction, and also on their axes.” The above statement applies to the formation of the solar system ; but it is only a part of the nebular hypothesis ; and why should the solar system be created, or formed in a man- ner different from the formation of other worlds comprising the universe ? And if this thin cosmic vapor originally filled the whole space, and even beyond that now occupied by the solar system, why should not a like cosmic vapor from which the entire universe has been formed exist and also fill all space ? This still leaves us in the dark as to how this cosmic vapor happened to be in existence before this motion com- menced. La Place thought he could dispense with the necessity of a creator, and substitute natural causes or laws in his place ; but he only pushed the inquiry one degree further back, and the question still recurs, what less than infinite intelligence and power could have instituted these laws of nature ? The monists contend that there is really but one original force in the universe, and that what we call living and dead matter are one and the same, as to their ultimate vital con- dition and forces. Haeckel says (in vol. 1, "History of Creation,” p. 23, as quoted in another place) : "We thus arrive at the extremely important conviction that all natural bodies which are known to us are equally animated, that the 157 EOBINET. distinction which has been made between animate and inani- mate bodies does not exist.” However, he is not the first to discover, even among moderns, that all things are "equally animated ; ” for, accord- ing to Henslow, Robinet wrote, more than a hundred years ago, that all things alike have sentient perceptions ; all grow, desire, and propagate. Thus he says, fire is hungry and voracious ; it feeds on air, and if air be wanting, it expires. So, too, air feeds on water, while water feeds on other sub- stances. And thus he accounts for such minerals as salt, iron, etc., being found in mineral springs. The following quotation will illustrate his style of reasoning : " I have sought for the germs of stones and the vessels which contain them ; nor have my researches been fruitless. I have even discovered how stones and minerals eject their germs. If I have been unable to detect their sexes, how many animals and plants are in the same condition ! Finally we have seen an infinity of foetal stones and metals in their wombs, with their envelops and placentas; we have seen them growing and nourishing them like animals. There may be stones which multiply by budding, as is the case with trees and some animals. But observations are wantingl to confirm this conjecture.” (" Evolution of Living Things,” pp. 16, 17.) The words, " Observations are wanting to confirm,” in this last sentence, are well introduced by Robinet; and I think that " observations ” to prove that all things are " equally animated ” will be " wanting to confirm that con- jecture ” for a long time to come. Monists contend that the forces which build the crystals are living as well as those which build the bodies of living animals, but the difference between the living and the dead, 158 THE DEVELOPMENT OF LIFE. or between the organic and inorganic matter, is radical. The crystal is built from the outside by natural forces, and when its particles or molecules are once placed in their natural positions, by inherent natural forces, they may remain asons of time without the least change, unless taken away by absorption or by being dissolved or ground away. To change a crystal in the least degree without mechani- cal violence, the very force which caused it to be built up must be reversed, and stronger forces must operate in a different direction. When the crystal is once built it is built to last forever, or till other forces in nature commence to take the molecules of which it is composed from the out- side, one by one, by forces just the opposite from that through which they were placed in position. But in all living animal organisms there is continuous motion through growth and decay. The living animal organism never remains stationary for a single second of time. In fact, the instant vital motion stops death takes place, or, more properly speaking, this vital motion or action always continues until death occurs. Ceasing of vital motion is death. It is true a living structure (a plant, for instance) may perish slowly, by almost imperceptible degrees ; but this decay is none the less sure because slow. It is useless to assert that the ultimate atoms of which in- organic matter is composed must of necessity in all cases be in constant motion, while we can produce no tangible evi- dence that such supposed condition of tilings really exists. Living motion is continuous in the very lowest animals ; but it is more easily perceived in the higher organisms. The forces which act to build the crystals come from with- out, while the active forces in living organisms come from within. How can we reasonably confound the two? QUATREFAGES. 159 Quatrefages (" Human Species,” pp. 4, 5) says: " The reason is that, in the organized being, the repose of the crystal is replaced by an incessant movement; that, instead of remaining immovable and unalterable, the mole- cules are unceasingly undergoing transformation, changing their composition, producing fresh substances, retaining some and rejecting others. Far from resembling a pile of shot, the organized being may much rather be compared to the combination of a number of physico-chemical appa- ratus, constantly in action to burn or reduce materials borrowed from without, and ever making use of their own substance for its incessant renewal.” "In other words, in the crystal once formed the forces remain in a state of stable equilibrium, which is only inter- rupted by the influence of exterior causes. Hence the pos- sibility of its indefinite continuance without any change either of its forms or of its properties. In the organized being the equilibrium is unstable, or, rather, there is no equilibrium, properly so called. Every moment the organized being expends as much force as matter, and owes its continuance solely to the balance of the gain and loss. Hence the possibility of a modification of its properties and form with- out its ceasing to exist. Such are the bare facts, which rest upon no hypothesis whatever; and how can we, in the presence of these facts, compare the crystal which grows in a saline solution to the germ which becomes in succession embryo, foetus, and finally a complete animal? How can we confuse the inanimate body with the organized being?” " But organized beings have also their special phenomena radically distinct from, or even opposed to, the former. Is it possible to refer all of them to one, or to several, identical causes? I think not. For this reason, I admit with a 160 THE DEVELOPMENT OF LIFE. great number of eminent men of every age and country, and, I believe, with the majority of those that respect modern science, that organized beings owe their distinctive charac- teristics to a Special Cause, to a Special Force, to Life, which, in them, is associated with the inorganic forces. For this reason I consider it legitimate to call them Living Beings.” At the first development or unfolding of life the living action in the vegetable is essentially like that in the animal. While the seed is germinating there is a constant molecular action, and this motion being continuous is like that in the lowest forms of animal life ; and in most cases it is not till the plant has risen above the surface of the ground and is acted upon by the sunlight, and chlorophil is absorbed by the plant, that what is generally considered distinctive vegetable life appears. All the protoplasm necessary to the growth of either plants or animals must be taken in a comparatively fluid state, and the particles placed where they belong, after which the water that has held these particles in solution is absorbed or evaporated. Vegetables take their nourishment from the outside through their rootlets or through their leaves. They also convert inorganic substances into organic, a thing which, generally speaking, animals cannot do. Animals generally take food through mouths into a stomach, and can be nourished by organic matter only. But some animals do not seem to have any stomach. The ultimate principle of life in the animal and the vege- table seems to be one and the same; but a very noticeable difference is, that, when the living particles are once firmly placed in a tree, they appear to be stationary, and not to change, as in the case of animals. Every part of animals, bones, muscles, and tissues, —is in a state of constant change. PERSONAL IDENTITY. 161 It is believed that not a single particle of matter which is in the child remains in his body till adult life is reached. But the wonderful fact remains that the individuality or personal identity continues though every particle of the matter of the body has been changed. What is this wonderful entity which preserves personal identity, and makes one still the same person though all else has been changed? Can it be other than a living force ? 162 THE DEVELOPMENT OF LIFE. CHAPTER VII. THE DEVELOPMENT OF LIFE. This chapter is chiefly devoted to further examination of various theories of the development of life. An actual fact is not changed, whether it is stated by one who is learned or by one who is comparatively ignorant, the fact still remains eternal truth. Agassiz believed that an almighty creative intelligence established the very laws of nature themselves. Had Agassiz yielded to the demands of that class who do not believe that a being of infinite intelligence was the originator of earthly existence, and taught that species came to exist through the laws of nature without the intervention of a creator, might he not have passed with them for a distributor of opinions of the highest scientific value? But every person who was fortunate enough to be acquainted with that gifted naturalist is convinced that he taught only what he believed to be true. Hseckel writes, p. 117 : "When, in 1873, the grave closed over Louis Agassiz, the last great upholder of the constancy of species and of miraculous creation, the dogma of the con- stancy of species came to an end, and the contrary assump- tion the assertion that all the various species descend from common ancestral forms now no longer encounters serious difficulties.” Suppose " that the assumption that all the various species descended from common ancestral forms now encounters no AGASSIZ. 163 serious difficulties ” in consequence of the death of Agassiz, does not that very statement seem to imply that the validity of that doctrine might be in some measure dependent upon the teachings of men ? What difference could the living or dying of any man make as to the truth or falsity of actual facts ? By constancy of species Agassiz meant that there has been no change of one species into another. Thus, he taught that lions are descendants of lions, or some ancestor of the cat family ; and sheep of sheep from their first crea- tion, and that the descendants of lions will be lions, and the descendants of sheep, sheep, etc., and that these animals will never in the future change into any other race of animals essentially different from the present races. He taught that the ancestors of men were men from their earliest creation, and their descendants, to their latest pos- terity, will also be men with mental and physical charac- teristics essentially like those now living. Most of those who indorse the theory of man’s descent from an original one-celled ancestor contend that there is a continuous line of development by the laws of nature. It should be borne in mind, however, that there are many firm believers in the doctrines of evolution who also firmly believe that an almighty creative intelligence established the laws of development, and that what we call the laws of nature are only the manifestations of his manner of Work- ing- Concerning Lamarck’s theory, Haeckel writes, vol. 1, "Evolution of Man,” p. 85; "Lamarck was the first to formulate the scientific theory of the natural origin of all organisms, including man, and at the same time to draw the two ultimate inferences from this theory ; firstly, the doctrine 164 THE DEVELOPMENT OF LIFE. of the origin of the most ancient organisms through spon- taneous generation ; and, secondly, the descent of Man from the Mammal most closely resembling Man, the Ape.” In attempting to explain how this came about, "he con- sidered that, on the one hand, practice and habit (adapta- tion), and, on the other, heredity, are the most important of these causes.” On page 86 he adduces examples as follows : "To mention examples, the Woodpecker and the Humming-bird owe their peculiarly long tongue to their habit of using these organs to take their food out of narrow and deep crevices ; the Frog acquired a web between its toes from the motions of swimming; the Giraffe gained its long neck by stretch- ing it up to the branches of trees.” " Lamarck fully perceived that Heredity must necessarily cooperate with Adaptation.” To sum up, he contends that the first step made by apes towards becoming men, was when they gave up the habit of climbing trees, and " accustomed themselves to an upright gait.” This exercise developed the spine and the pelvis ; and the fore-legs, instead of being used for climbing, devel- oped into arms and hands for the " purpose of grasping and touching,” while the hind pair were used for walking, and their extremities were developed into true feet. "In conse- quence of the totally changed mode of life,” there came a change of jaws and teeth, and, consequently, of the whole shape of the face. The tail, no longer needed, disappeared. Then, as the apes began to live in communities, social instincts developed, and family relations began to subsist, and the apes’ language of sounds developed into the language of men, etc. Then the brain changed its shape, and grew larger by its more constant use, etc. LAMARCK. 165 " These important ideas of Lamarck contain the first and oldest germs of a real history of the human tribe.” To give the reader, as clear an idea as possible of the theories of Lamarck and others of his school in a small compass, I will quote a summary from Dr. Edward Hitch- cock ("Religion of Geology,” pp. 289, 290) : "The French zoologist, Lamarck, first drew out and formally defended this hypothesis, aided by others, as Geoffrey St. Hilaire and Bory St. Vincent. Their supposition was that there is a power in nature, which they sometimes denominated the Deity, yet did not allow it to be intelligent and indepen- dent, but a mere blind, instrumental force. This power, they supposed, was able to produce wdiat they called monads, or rough draughts of animals and plants. These monads were the simplest of all organic beings, mere aggregations of matter, some of them supposed to be inherently vital. And such monads are the only tilings ever produced directly by this blind Deity. But in these monads there was supposed to reside an inherent tendency to progressive im- provement. The wants of this living mass of jelly were supposed to produce such effects as would gradually form new organs, as the hands, the feet, and the mouth. These changes would be aided by another principle, which they called the force of external circumstances, by which they meant the influence upon its development of its peculiar con- dition ; as, for instance, a conatus for Hying, produced by the internal principle, would form wings in birds ; a conatus for swimming in water would form the fins and tails of fishes; and a conatus for walking would form the feet and legs of quadrupeds. Thus the organs were not formed to meet the wants, but by the wants of the animal and plant. Of course, new wants would produce new organs ; and thus 166 THE DEVELOPMENT OF LIFE. have animals been growing more and more complicated and perfect from the earliest periods of geological history. Man began his course as a monad ; but, by the force of Lamarck’s two principles, has reached the most elevated rank on the scale of animals. His last condition before his present was that of the monkey tribe, especially that of the orang- outang.” Lamarck has much more of similar import, carrying out and developing ideas of which these are the bases ; but what wants first inclined these apes to give up " the habit of climb- ing trees,” and adopt " an upright gait,” so that their fore- legs became "developed into hands and arms,” and their " extremities were developed into true feet ” ? Also, how did these monads become possessed of an " inherent tendency to progressive improvement ” ? And Avhat first caused those wants which led to the formation of new organs ? Supposing this theory is substantially correct, does any one know that these so-called new organs did not exist in a rudimentary state before there was any known tendency to develop new organs ? Who knows that some which are now called useless rudimentary organs may not yet become developed into active and useful organs ? Did the trees cease to give the apes food, and were they thus obliged to resort to the ground to find food ? And is this the reason why they gave up their arboreal habits ? And if they went upon the ground for food, why should they walk upright, instead of upon four feet as before ? Again, it should be borne in mind that Lamarck com- pletely begs the question, for he does not show that any race of apes from which man might have been developed, existed on the earth prior to the existence of men. He seems to take it for granted that development is upward ; but if it DR. HITCHCOCK. 167 should be shown that there has also been a degeneration in some races as well as an upward development in other races, his principles might not apply here. Plato accounted for the degradation of the quadrupeds and creeping animals by the fact that their lower propensities naturally drew them nearer the earth. To show that there has been a degradation in some races, I will quote from Dr. Hitchcock, pp. 313, 314 : "'The lower Silurian,’says Sir Roderick Murchison, in 1847, ' is no longer to be viewed as an invertebrate period ; for the onchus (a genus of fish) has been found in the Llandeilo Flags, and in the lower Silurian rocks of Bala. " rlt is also a most important fact, that this fish of the oldest rock was not, as the development scheme would require, of a low organization, but quite high on the scale of fishes. The same is true of all the earliest species of this class.’ ' All our most ancient fossil fishes,’ says Trofessor Sedwick, 'belong to a high organic type; and the very oldest species that are well determined fall naturally into an order of fishes which Owen and Muller place, not at the bottom, but at the top of the whole class.’ " This point has been fully and ably discussed by Hugh Miller, Esq., in his late work, ' The Footprints of the Crea- tor, or the Asterolepis of Stromness.’ The asterolepis was one of these fishes found in the old red sandstone, sometimes over twenty feet long; yet, says Mr. Miller, ' instead of being, as the development hypothesis would require, a fish low in its organization, it seems to have ranged on the level of the highest ichthyic-reptilian families ever called into existence.’ " Another point which Mr. Miller has labored hard to establish, and of which there seems to be no reasonable 168 THE DEVELOPMENT OF LIFE. doubt, is, that in many families of animals, not only were the first species that appeared of high organization, but there was a gradual degradation among those that were created afterwards. Of the fishes, generally, he says that 'The progress of the race, as a whole, though it still retains not a few of the higher forms, has been a progress, not of development from the low to the high, but of degradation from the high to the low.’ .Again, he says, 'We know, as geologists, that the dynasty of the fish was succeeded by that of the reptile ; that the dynasty of the reptile was succeeded by that of the mammiferous quadruped; and that the dynasty of the mammiferous quadruped was succeeded by that of man, as man now exists—a creature of a mixed character, and subject, in all conditions, to wide alternations of enjoyment and suffering. We know further, —so far, at least, as we have succeeded in deciphering the record, that the several dynasties were introduced, not in their lower, but in their higher forms; that, in short, in the imposing programme of creation, it was arranged as a general rule, that in each of the great divisions of the pro- cession the magnates should walk first.’ ” Upon the testimony of men like the Duke of Argyll, and Virchow we learn that the oldest fossil human skulls yet discovered are of a high rather than a low order. Looking from this stand-point, why, in absence of proof to the con- trary, may we not infer that the early races of men may have been of a high rather than of a low order, as well as to receive as proved, what the rocks testify, viz., that cer- tain very early classes of fishes were of a high order ? All pertinent testimony should be carefully and dispas- sionately weighed, and all germane facts receive due con- sideration, and the strongest, most direct, and weighty RADICAL DOCTRINES. 169 evidence should prevail. But here is a balancing of proba- bilities rather than an actual weighing of positive evidence; for much of what some consider positive evidence may be of a doubtful character. What one considers positive evidence another may consider hypothetical. The evidence in favor of the general principles of evolu- tion appears satisfactory to a majority of the students of natural history, and hence the probability that these general principles are correct; but certain radical evolutionists assert that arguments nearly equivalent to a demonstration have already been presented, and intimate that those who cannot see this are lacking either in learning or intellectual ability. But accusations of ignorance and want of logical power should have no place here; for a correct decision must rest upon actual facts. If we assert that woodpeckers’ tongues are now longer than they were five thousand years ago (of which assump- tion no proof has been given), then, who gave these wood- peckers a disposition to stick their comparatively short tongues into deep and narrow crevices to get their food? Why, if their tongues were originally short, should they commence putting them into such narrow and deep crevices, rather than take such food as other birds sought? So with the humming birds, and the giraffe. Who gave the giraffe a disposition to reach high for its food, and thus develop such a long neck? If it is asserted that the giraffes were obliged to reach high among; the trees for food on account of the failure of lower vegetation, we want evidence that such was the case. What evidence have we that animals with short necks and which feed off the ground have not lived and their descend- ants been preserved in localities inhabited by these giraffes ? 170 THE DEVELOPMENT OF LIFE. Unless some such evidence can be presented, such supposi- tions of development are unsatisfactory because of the ab- sence of facts in their support. I have given you an epitome of these theories ; the one supposes that the woodpecker, and the humming-bird and the giraffe, were, from the commencement of their existence, as distinct species, peculiarly fitted for obtaining their food as they now do ; and being thus formed is why they now, as always before, obtain their food each in his own peculiar manner. The other theory supposes that the giraffes’ necks and the woodpeckers’ tongues were originally short, but have been developed to much greater length by their peculiar modes of getting food. Mivart (" Genesis of Species,” pp. 36, 37, 38) on this theory remarks : " But some of the cases which have been brought forward, and which have met with very general ac- ceptance, seem less satisfactory when carefully analyzed, than they at first appear to be. Among these we may mention ' the neck of the giraffe.’ " At first sight it would seem as though a better example in support of' Natural Selection ’ could hardly have been chosen. Let the fact of the occurrence of occasional severe droughts in the country which that animal has inhabited be granted. In that case, when the ground vegetation has been consumed, and the trees alone remain, it is plain that at such times only those individuals (of what we assume to be the nascent giraffe species) which were able to reach high up would be preserved, and would become the parents of the following generation, some individuals of which would, of course, in- herit that high-reaching power which alone preserved their parents. Only the high-reaching issue of these high-reach- MI V ART 171 ing individuals would again, coster is paribus, be preserved at the next drought, and would again transmit to their off- spring their still loftier stature; and so on, from period to pei’iod through aeons of time, all the individuals tending to revert to the ancient shorter type of body, being ruthlessly destroyed at the occurrence of each drought. "But against this it may be said, in the first place, that the argument proves too much ; for, on this supposition, many species must have tended to undergo a similar modification, and we ought to have at least several forms similar to the giraffe developed from different Ungulata. A careful observer of animal life, who has long resided in South Africa, explored the interior, and lived in the giraffe country, has assured the author that the giraffe has powers of locomotion and endurance fully equal to those possessed by any of the other Ungulata of that continent. It would seem, therefore, that some of these other Ungulates ought to have developed in a similar manner as to the neck, under pain of being starved, when the long neck of the giraffe was in its incipient stage. " To this criticism it has been objected that different kinds of animals are preserved, in the struggle for life, in very different ways, and even that' high reaching ’ may be attained in more modes than one, —as, for example, by the trunk of the elephant. This is, indeed, true, but then none of the African Ungulata have, nor do they appear ever to have had, any proboscis whatsoever; nor have they acquired such a development as to allow them to rise on their hind limbs and graze on trees in a kangaroo attitude, nor a power of climb- ing, nor, as far as known, any other modification tending to compensate for the comparative shortness of the neck. Again, it may perhaps be said that leaf-eating forms are ex- ceptional, and that, therefore, the struggle to attain high 172 THE DEVELOPMENT OE LIFE. branches would not affect many Ungulates. But surely, when these severe droughts necessary for the theory occur, the ground vegetation is supposed to be exhausted, and in- deed the giraffe is quite capable of feeding from off the ground. So that, in these cases, the other Ungulata must have taken to leaf-eating or have starved, and thus must have had any accidental long-necked varieties favored and preserved exactly as the long-necked varieties of the giraffe are supposed to have been favored and preserved.” But I am told that short-necked vegetable-eating animals live in the same localities as the long-necked giraffes. Why have not these short-necked races become long-necked, or died out during the protracted droughts, if long necks were necessary to the preservation of existence ? Put these state- ments side by side. But we know that animals, under the guidance of men, have been developed into very strong and excellent specimens of their races; but there is no definite evidence that different breeds of domestic animals have developed themselves into particularly strong races without intelligent guidance outside of themselves ; though diversities of climate, kinds of food, laws of heredity, " natural selection,” and other outward circumstances, doubtless greatly tend to modify the character and strength of races of animals as well as of men. There is no doubt that the descendants of weak and bar- barous races, through the influence of food, climate, educa- tion, habits of living, etc., have become developed into strong and civilized races, nor that the descendants of strong and vigorous races, through bad habits of living, improper food, etc., may degenerate into much lower types of humanity. And it is probable that many of what are classed as different species (more properly varieties) may, DUKE OE ARGYLL. 173 during the ages past, have descended from some common ancestor. But it should be kept in mind that it is one thing to believe that animals and plants now classed as different species have descended from some common ancestor; and it is quite another to unhesitatingly accept the statement that men have been developed from an ape-like mammal. Until one is prepared to accept this last dogma he will by some be considered illogical to stop half-way on the evolutionary road. The Duke of Argyll, in "Primeval Man” (p. 39, 40), says : " But no such experience ever comes to us casting any light on the Origin of our own Race, or of any other. Some varieties of form are effected, in the case of a few animals, by domestication, and by constant care in the selection of peculiarities transmissible to the young. But these varia- tions are all within certain limits ; and, wherever human care relaxes or is abandoned, the old forms return, and the selected characters disappear. The founding of new forms by the union of different species, even when standing in close natural relation to each other, is absolutely forbidden by the sentence of sterility which Nature pronounces and enforces upon all hybrid offspring. And so it results that man has never seen the origin of any species. Creation by birth is the only kind of creation he has ever seen; and from this kind of creation he has never seen a new species come.” The world is full of analogies, and we can learn much from these if we rightly interpret them. A tree, for in- stance, in physical construction, is, in a general way, a type of the physical construction of many species of animals. Even a leaf is a type of the tree and of a vertebrate animal. Most leaves have a vertebral column, ribs, etc., and a breathing apparatus. 174 THE DEVELOPMENT OF LIFE. How similar the construction of a pod of the common pea to the body of a man ! It has a vertebral column and ribs, and the peas themselves are located in a manner similar to the viscera and reproductive organs of vertebrate animals. How strangely like living actions are the operations of frost in making the appearance of leaves upon the window- glass ! Can that which forms these frost-leaves be the same force as that which forms the leaves upon the trees, which they so much resemble? When we say a tree is a physical type of animated nature, we refer to its structure, growth, and vital properties ; for trees and animals are developed from germs in a precisely similar manner, and in their secretion and exhalations they are wonderfully similar. But, if animals and men have been developed from an original one-celled ancestor, it seems to me that there must have been a preexisting vital principle to give life to the monera, or they would have never existed as living organ- isms. We can easily understand what is generally meant by the term r spontaneous generation.” I might rest here with a flat denial of this foundation principle till some one could show us that ” spontaneous generation ” now takes place. But many are accustomed to connect a theory and its starting-point together, not per- ceiving that it is possible for a theory to be correct after it has left its starting-point, while the very foundation on which the starting-point rests may be perfectly unreliable. The starting-point, " spontaneous generation,” appears to have no actual basis, as the experiments of M. Pasteur, Tyndall and others have proved. But if we recognize the existence of an almighty creative intelligence, and allow that this creative power was the RESEMBLANCES. 175 cause of life, all seems to follow naturally and logically to the final conclusion. All animated forms indeed bear a resemblance in certain particulars. Thus when we are told that the chick in the egg, from the commencement of incubation to the time it breaks its shell and runs free, is a type of the development of the embryo in all the higher forms of animal life, we hear what is doubtless true. Notwithstanding the fact that the theory is very plausible, it by no means follows that, because during the forty weeks preceding the birth of a human child stages typical of or similar to certain different races that have existed or now exist among the lower orders of creation are passed through, therefore man is descended through races of O ' o animals, of which these changes in the embryo are a type. It by no means follows that, because oxen and horses are quite similar in their general physical structure and disposi- tions, therefore, they must have descended from some com- mon ancestor. If we are to deal in assumptions or presumptions, why may we not as well assume, as our fathers did, that the Creator originally designed all animal life on one general plan, but with almost infinite variations? It should be borne in mind, however, in regard to the origin of life, that Darwin disagrees with Hasckel; for Darwin did not intimate that he believed in " spontaneous generation,” but acknowledged that the Creator originally breathed the breath of life into the " original forms or form of life.” By the term " bona species ” Agassiz meant absolutely different races which do not interbreed, and not those which 176 THE DEVELOPMENT OF LIFE. are similar, like the wolf and the dog, which do interbreed and produce a progeny of wolf-dogs. Dr. Eheckel charges (p. 116), that "The divine Creator, as represented by Agassiz, is but an idealized man, a highly imaginative architect, who is always preparing new building plans and elaborating new species.” If the Creator, or this underlying invisible Power, is in His nature incomprehensible (as I believe He is), how does any one know that the much-ridiculed " anthropomorphic concep- tions ” are entirely incorrect ? Why assume that particular " conceptions ” of Him are essentially wrong, while we can- not tell whether such conceptions are correct or incorrect ? When one assumes that he knows that the Creator cannot exist and act in certain ways, does he not, by that very assumption, virtually claim that he can tell how He may exist and act? Does not such an assumption virtually set a limit to the .powers of the Creator ? Why may not the Creator (if He chooses), work on new creations now as well as in the beginning ? New varieties of living creatures are being discovered. Who knows that some of these are not new creations ? Who knows that new worlds are not now in process of construction ? Who knows that comets are not the nuclei around which, aeons hence, new worlds may be in process of construction ? If the solar system was evolved from cosmic vapor, and was aeons in being consolidated, why may not cosmic vapor still exist which is not yet consolidated, from which other worlds may yet be constructed? Possibly the earth may have been con- structed or consolidated millions of ages subsequent to the construction of the great suns which we call the fixed stars. Does any man know to the contrary? Has the Creator become so tired that Pie must rest, and let all the mighty HiECKEL. 177 powers and forces of nature run without His personal super- vision? Why should those who deny the existence of a personal almighty intelligence, claim exclusive knowledge of the mysteries of our existence? Again, on these questions of our descent, when reasoning from peculiarities of our physical organism, we may well suppose that physiologists know something. Yet Haeckel says (p. 20, vol. 1, "Evolution of Man ”) : "Physiology, however, has, especially during the last twenty years, been far more one-sided in its progress than Morphology. Not only has it entirely neglected to apply the comparative method, by which Morphology has gained its greatest results, but it has altogether disregarded the History of Evolution.” Also (on p. 21), he says : "Indeed the direction at present taken by Physiology is so one-sided that it has even neglected the recognition of the most important functions of Evolution, namely, Heredity and Adaptation, and has left this entirely physiological task to morphologists.” This is a virtual confession that physiologists have not generally received to their full extent the doctrines of evo- lution. Many have adopted these doctrines in their general appli- cation ; but not so many as radical evolutionists claim have adopted them in their full extent. Physiologists are slow to do so. But the general principles which underlie the popular development theory are very ingeniously explained, and the " spontaneous generation ” part of the theory is peculiarly palatable to such as would vote the Creator out of existence. And yet, if the Creator has chosen to create and develop men according to the theory of Darwin or Haeckel, or even according to the theories of their most radical disciples, who shall question His right or power to do so ? 178 THE DEVELOPMENT OF LIFE. Another reason why some receive the radical development theories may be seen by looking at the history of scientific theories for the past two thousand years. When new and startling theories have been broached, they have created a sort of philosophic craze, and the vagaries have their run, like a fever, till burned out, or till some succeeding theory swallows up the preceding. It is now in some respects as it was in the days of Paul, many want "to hear or tell some new thing," and if enough that is new cannot be found in the real, then something new must be invented. Or, as Huxley said, when referring to the ingenuity displayed by Haeckel in his "History of the Creation,” "Whether one agrees or disagrees with him, one feels that he has forced the mind into new lines of thought in which it is more profitable to go wrong than to stand still.” So a great many now are better pleased to receive unproved theories than to stand still. It has often been asked, if species do interchange, or so develop as to become radically different races, why have we not some evidence during the past four thousand years that some one species has changed into or towards some other specific species ? Why, since evolutionists are so particular about facts from experience, or experimental knowledge, do they not show facts to prove their theory, instead of pointing to so many analogies, and asserting that these establish their theory ? It is true that during thousands of ages, in geologic time, by an almost infinite number of accretions of infinitesimal differ- ences, animals may, and probably have, essentially changed in construction and appearance, when so short a time as four thousand years might make no appreciable difference. But, 179 LAW OF BIOGENY. admitting that this may be probable, the burden of proof still rests upon the evolutionists. One sti'ong point of Dr. Haeckel’s theory, and one which he repeats over and over again, is what he calls, "the funda- mental law of organic evolution, or the first principle of biogeny ” (pp. 6, 7), and it is thus expressed: "The series of forms through which the individual organism passes during its progress from the egg-cell to its fully-developed state, is a brief, compressed reproduction of the long series of forms through which the animal ancestors of that organism (or the ancestral forms of its species) have passed from the earliest periods of so called organic creation down to the present time.” This is his law, and it is clearly enough expressed, and it is the very corner-stone of his fabric. And it must be con- fessed that he has made this theory appear very plausible; but if he could prove that the changes which the chick in the shell goes through are an exact type of all the changes which the chick’s mature ancestors have gone through during the millions of years since it came (through the process of development) from an original one-celled ancestor, then his whole case would be proved, and it would be useless to combat it. But he assumes the very fact that needs to be proved. How does he know that these changes in the chick are a type of its previous ancestors through the many stages of development? He mentions certain facts that seem to point in that direction. But is that proof? No. The whole theory rests upon assumption ; but no man can tell for a certainty whether it is a true or a false assumption. The point under consideration is important, for it is fun- damental. One school asserts that the changes in the human embryo are a type of the mature animals of the 180 THE DEVELOPMENT OF LIFE. ancestral races through which, by the process of develop- ment, men have descended. One can readily see, by following out analogies which we find in nature, from the smallest particles of matter which we can discover with the microscope to the planets them- selves, that there are striking resemblances, and that there are certain general laws applicable to all. All nature in its action seems like a wheel within a wheel; but Ido not see why we should assume that the development of the chick in its shell and the development of the human embryo should be like the progressive stages of development which the mature ancestors of the embryo or chick have passed through in each succeeding generation from their original ancestors, any more than the development of the chick in the shell should be typical of the growth of the chick from the time of hatching through the whole of its remaining physical existence, or from its birth to its death. I would not raise objections against the plausibility of this " Law of Biogeny ; ” but it is the positiveness with which its truth is asserted which troubles me. I simply protest against drawing positive and sweeping conclusions too hastily from insufficient data. But, if it be shown that the human embryo is never like any mature animal, but is simply like another embryo, then the doctrine of this equivalence, or general agreement with other races, is greatly weakened. Now let us see what competent naturalists assert. Ac- cording to K. E. von Baer, as quoted by Agassiz ("Classification,” pp. 351, 352), "the results at which K. E. von Baer had arrived by his embryological in- vestigations respecting the fundamental relations existing among animals, differed considerably from the ideas then K. E. VON BAER. 181 prevailing. In order, therefore, to be correctly understood, he begins, with his accustomed accuracy and clearness, to present a condensed account of those opinions with which he disagreed, in these words: 'Few views of the relations existing in the organic world have received so much appro- bation as this : that the higher animal forms in the several stages of the development of the individual, from the be- ginning of its existence to its complete formation, corre- spond to the permanent forms in the animal series, and that the development of the several animals follows the same laws as those of the entire animal series ; that, consequently, the most highly organized animal, in its individual develop- ment, passes, in all that is essential, through the stages that are permanent below it, so that the periodical differences of the individual may be reduced to the differences of the per- manent animal forms.’” Now let us see what von Baer did find from his investi- gations (p. 857, Agassiz). He says, "Comparing these four types with the embryonic development, von Baer shows that there is only a general similarity between the lower animals and the embryonic stages of the higher ones, arising mainly from the absence of differentiation in the body, and not from a typical resemblance. The embryo does not pass from one type to the other ; on the contrary, the type of each animal is defined from the beginning, and controls the whole development. The embryo of the Ver- tebrate is a Vertebrate from the beginning, and does not exhibit at any time a correspondence with the Invertebrate. The embryos of Vertebrates do not pass, in their develop- ment, through other permanent types of animals. The fun- damental type is first developed, and afterwards more and more subordinate characters appear. From a more general 182 THE DEVELOPMENT OF LIFE. type the more special is manifested; and the more two forms of animals differ, the earlier must their development be traced back to discern an agreement between them. It is barely possible that, in their first beginning, all animals are alike, and present only hollow spheres ; but the individ- ual development of the higher animals certainly does not pass through the permanent forms of lower ones. What is common in a higher group of animals is always sooner de- veloped in their embryos than what is special; out of that which is most general arises that which is less general, until that which is most special appears. Each embryo of a given type of animals, instead of passing through other definite types, becomes, on the contrary, more and more unlike them. An embryo of a higher type is, therefore, never identical with another animal type, but only with an embryo.” If von Baer was correct in this statement then those who have stated that the human embryos pass through all the essential distinctive characteristics which remain permanent in the species which are below it must be in error; and thus, this would seem to be in opposition to Hasckel’s " Law of Biogeny.” Other learned naturalists besides Agassiz agree with von Baer. Prof. Orton (p. 201, "Comp. Zoology”) says : " At the outset, all animals, from the sponge to man, are indistinguishable from one another. They are mainly drops of fluid, a little more transparent on one side than the other; and, in all cases, this almost homogeneous globule must develop three well-defined parts, a germinal dot, germinal vesicle, and yolk. But while vertebrates and in- vertebrates can travel together on the same road up to this point, here they diverge, never to meet again. For, every grand group early shows that it has a peculiar type of con- struction. Every egg is from the first impressed with the SIMILARITIES. 183 power of developing in one direction only, and never does it lose its fundamental characters.” Let us, however, not forget what has been before stated, that, on account of the general peculiarities which, with numerous variations, run through the whole universality of living things, it may not be unreasonable to suppose that the law of organic evolution may embody types of all living beings which have ever existed or ever will exist; and that the development of an acorn into an oak, or a chick into a fowl may in some respects be typical of the development of all animated nature ever since animated nature existed. That resemblances should run through nature in all its forms is indeed wonderful; but, the more wonderful this is, the greater the necessity for the existence of an intelligent worker to make all things in such similar correspondence, even to the certainty of the shape of the various crystals formed by the evaporation of solutions. The perfectly un- varying laws that govern all things appear to be the work of some infinitely high intelligence. But, if the changes passed through during the forty weeks necessary for the development of the human embryo to a perfect infant, or the three weeks for the development of the chick in the shell, or the uncertain or indefinite time during which an acorn develops into an oak, are partial types of the arrangements of all animated nature, that does not by any means prove that present species of animals have been developed out of radically different species of animals ; nor does it by any means show that the human race must have passed through a line of ancestral forms similar to all the changes which take place in the embryo before the perfect human physical system is developed. There are several stubborn facts which seem to indicate 184 THE DEVELOPMENT OF LIFE. that the theory of the descent of man through apes is not correct. De Quatrefages states that the angle of the sphenoid bone, or the bone upon which the brain rests, con- stantly grows less as the human approaches manhood; while in the apes, the angle of this bone grows larger, averaging about twenty-seven degrees greater in mature apes than in infant apes. And he adds ("Human Species,” p..380) : " I have already insisted that facts of this nature are irrecon- cilable with those theories which attribute a more or less pithecoid ancestor to man.” Peschel says (p. 4 "Races of Man ”) : " Finally, the early disappearance of the intermaxillary bone in the human in- fant may be cited as a distinction from the apes. " These last facts oblige us to glance at the evolutionary history of man, which has gained great importance since Johann Friedrich Meckel, of Halle, asserted, in 1812, that every animal in its immature condition (and this lasts from the fecundation of the egg to the first sexual functions) passes through all the forms which occur during the entire life of the animals of every grade beneath it. " At the time of birth the gap between the child and the young of the ape is as yet very narrow. The brains of children and young apes approach very closely in size, but of all parts of the body the brain of the ape grows the least. Thus, although the brain of the anthropomorphous ape con- tains all the main parts of the human skull, its development, nevertheless, assumes quite another direction.” . " Before the change of teeth has begun, the brain of the ape has usually attained its completion, whereas, in the child its proper development is just then actively beginning. "In the apes, on the contrary, the facial bones grow in an animal direction, so that finally the largest ape has the VIRCHOW. 185 brain of a child and the jaws of an ox. Thence it follows that a man would never originate from the progressive evolu- tion of the apes, for their development is directed to different ends, and the longer they advance towards these ends the greater are the contrasts.” Prof. Yirchow, in an address at Munich, before quoted from (according to Billing, p. 79, "Scientific Material- ism”) , said : " I should not be alarmed if proof were found that the ancestors of man were vertebrated animals. I work by preference in the field of anthropology ; yet I must declare that every step of positive progress which we have made in the domain of prehistoric anthropology has really moved further away from the proof of this connection. Cuvier maintained in the quaternary period man did not exist; but now quaternary man is a real doctrine, tertiary man a problem, and yet there are questions in discussion for the existence of man during the tertiary period. Even ecclesi- astics admit, as Bourgeois, that man existed in the tertiary period. Quaternary fossil man we find just the same as our- selves. Only ten years ago, when a skull was. found in peat, or in the lake dwellings, a wild and undeveloped state was seen in it. We were then scenting monhey air, but these old troglodytes turn out to be quite respectable society. Our French neighbors warn us not to count too much on these big heads ; it may be possible the old brains had more intermediary tissue than those of the now day, and that their nerve substance, notwithstanding the size of the receptacle, remained at a low state of development. Com- paring the total of fossil men found with the existing types, we find that, in the present, there is relatively a much larger number of lower types than there were in that period. 186 THE DEVELOPMENT OF LIFE. " In the fossil types the lower developments are absolutely wanting. That only the higher geniuses of the quaternary period were preserved I dare not suppose, but this can be said, that one fossil monkey skull or ape-man has never been found. It is possible in some special spot on earth tertiary man lived, for the remarkable discovery of the fossil ancestors of the horse in America, from which the horse had entirely disappeared, gives countenance to the idea. It may be that tertiary man has existed in Greenland or Lemuria and will be brought to light somewhere or other. We cannot teach, we cannot designate it as a revelation of science, that man descends from the ape or a?iy other animal. Bacon said, with perfect truth, ' scientia est potentia’ (knowledge is power) ; but the knowledge he meant was not specu- lative, not the knowledge of problems, but the objective knowledge of facts. We should abuse and endanger our power if, in our teaching, we do not fall back upon this perfectly justified, perfectly safe, and impregnable domain.” There is no reliable evidence that apes from which men could be developed lived before man existed. If they did not so exist, how can man be descended from them? If they did so exist, why has not a fossil monkey or ape-man’s skull ever been found? Such remains may yet be found; but until they are found, the acceptance of the above theory of descent must be received as provisional only. What is stated to be fact in the above can be safely con- sidered fact, and one fact is worth more than a score of scientific suppositions. Another stubborn fact that seems to go against the Darwinian theory of human descent is, that man, in the very earliest stages of his existence, even to the PKIMEVAL MAN. 187 oldest skeleton ever discovered, shows no greater resemblance to the apes than present races of men do. The Duke of Argyll, as previously quoted, says (p. 73, " Primeval Man”) : " The other skeleton, respecting which the evidence of extreme antiquity is the strongest, is not only perfectly human in all its proportions, but its skull has a cranial capacity not inferior to that of many modern Europeans. This most ancient of all known human skulls is so ample in its dimensions that it might have contained the brains of a philosopher.” The point mentioned by Virchow concerning man in the tertiary period is of importance; but, even supposing that man dates back no farther than the quarternary period, one is naturally inclined to ask a mathematical question, viz., if we go back 30,000 to 50,000 years, and find that at that time there was a smaller proportion of individual men of a low type than there is at the present time, how far back must we go to make a connection between men and apes ? It is one thing to be possible, and quite another to be probable ; and even probability falls very far short of proof. Is it fair and philosophical to claim that a mere hypothesis is already equivalent to a fact, because no one has yet been able to show that the hypothesis is not founded in fact? It is common for parties to make rash statements, and then, if no one can show that these statements are actually untrue, to claim that they have shown them to be true. Thus a thousand statements may be made concerning which no demonstrations exist either for or against; but what do such statements amount to? Is it not unphilosophical to claim all things which are uncertain to be on our side of the argument? Suppose one should lay claim to all property, real and personal, concerning which there is uncertainty of 188 THE DEVELOPMENT OE LIFE. ownership,—how would that work? Thus, in arguments, the class of uncertain claims should have its due weight; but its due weight, in many cases, amounts to about zero. Some one has said that it will not do to tell school-boys that some things are certain and others uncertain ; for they will get things mixed, and believe the facts to be the uncertain things, and some of the uncertain things to be facts ; but when we are talking to educated men, or to philosophers, it will do to confess that there are many things which we do not know for a certainty. I trust my readers will be so much like philosophers that they will not mistake the uncertain things for the certain, or reject positive facts, and receive as facts things which are uncertain. Certain Avriters have accused the believers in a creative theory Avith accepting absurd notions. Can there be greater folly, while the atheistic are themselves ignorant of the character or mode of existence of that almighty force or power which underlies all the mani- festations and phenomena of life? Man has the highest intelligence of any being concerning whom they have positive knowledge. How can they, in their own minds, form a con- ception of an intelligent being, acting from reason, who does not reason in a manner somewhat similar to the reasonings of the most intelligent men? They extol reason, and call it the only unerring guide. Why then, should not the highest intelligence we can conceive of work also in accordance with some unerring guide? I am aware that Omniscience may have no need of any process of reasoning; for, knowing all things, He must be without the necessity for any course of reasoning; yet I cannot understand how Omniscience and Omnipotence com- bined should have ordained and established the immutable laws of nature without some reasons for so doing. INFINITE INTELLIGENCE. 189 Could we conceive of a man with infinite intelligence, would he not be likely to reason in some respects as a finite being does ? How do we know that finite reason may not be in some respects typical of infinite reason ? Let the wisest show us the actual truth concerning infinite wisdom and intelligence, if he can. 190 THE DEVELOPMENT OF LIFE. CHAPTEE YIII. DOES LIFE INHERE IN MATTER ITSELF? It would seem to ordinary observers that there must be a distinct line between the dead and the living. Hseckel denies that such a line exists in such a sense as is generally supposed. Others have, in substance, stated that organic and inorganic matter shade into, or so intermingle with each other that no distinct line between the dead and the living can be drawn. If asked to state upon what facts they base the opinion that there is no absolute vital difference between dead and living matter, they may cite the ultimate atoms, and assume that they are endowed with the principle of life, providing there be such a thing as a life principle. They might also mention the theory of Leibnitz in relation to monads. Leibnitz believed monads to be mathematical points, —r' the simple active elements of things, the veritable, living atoms of nature, the immaterial, indivisible and final forces of the universe.” He held that both mind and matter are composed of monads, but that mind is represented by conscious monads, and matter by unconscious monads. "But these two classes of monads are wholly unlike, and exert no influence on each other,” a conclusion to which materialists will hardly assent. If all the original and ultimate atoms are alike, and en- dowed with the same properties, then the living and the dead are composed of these atoms. Materialists do not acknowledge a vital principle separate NEEDHAM AND BUEFON. 191 from matter, but consider life merely a result of the action of matter ; or that life is a mere condition or process depend- ing entirely upon the action of matter. Following out this idea, some consider death to he simply a molecular change. A similar idea of death is mentioned by Huxley in connection with the opinions of Needham and Buffon. Needham, how- ever, believed in indestructible living particles of matter, as distinguished from non-living particles. Huxley (pp. 355, 356, " Lay Sermons ” ) states Needham’s opinions as follows ; " Life is the indefeasible property of certain inde- structible molecules of matter, which exist in all living things, and have inherent activities by which they are distinguished from not living matter. Each individual living organism is formed by their temporary combination. They stand to it in the relation of the particles of water to a cascade or a whirlpool; or to a mould into which the water is poured. " The form of the organism is thus determined by the re- action between external conditions and the inherent activi- ties of the organic molecules of which it is composed; and, as the stoppage of a whirlpool destroys nothing but a form, and leaves the molecules of the water, with all their inherent activities intact, so what we call the death and putrefaction of an animal, or of a plant, is merely the breaking up of the form, or manner of association, of its constituent organic molecules, which are then set free as infusorial animalcules. " It will be perceived that this doctrine is by no means identical with Abiogenesis, with which it is often confounded. On this hypothesis, a piece of beef, or a handful of hay, is dead only in a limited sense. The beef is dead ox, and the hay is dead grass ; but the " organic molecules ” of the beef or the hay are not dead, but are ready to manifest their vitality as soon as the bovine or herbaceous shroud in which 192 THE DEVELOPMENT OF LIFE. they are imprisoned are rent by the macerating action of water.” Various other like theories seem to be intertangled to a great extent, and may live to be discussed ages hence; but the science of modern chemistry has dispelled these illusions of Needham and Buffon, and probably further investigation will demonstrate the untenableness of many other opinions on this point. In some cases it is extremely difficult to tell just where this line between life and death is drawn. In certain cases, it may be impossible to distinguish between organic and in- organic matter, even with the most powerful microscopes; for the organic matter may have lines of structure so fine that we cannot discover them, and living organisms may be so minute that we cannot discover them. Organic matter may be structureless. It may be impossible in some cases to tell whether or- o-anic matter is dead or alive. But because not obvious no one has a right to assume that this distinction does not O exist. If we break a piece from a block of marble the piece we take off remains of the same quality as it originally was. The separation does not change the quality or manner of its existence ; but if we break a branch from a living plant or tree how soon this branch changes, and the difference between the living and the dead branch appears. The marble statue is largely composed of the remains of once living beings. But when one states that organic jpid inor- ganic matter are equally living, if the organic matter is in liv- ing animals, we see the inaccuracy of the statement. But when the statement is made concerning what we cannot readily class, though the dividing line may be absolute, it GRINDON. 193 makes a vast difference with many as to the truth or falsity of the statement. The following passage, taken from Leo H. Grindon, gives his idea of life as manifested in inorganic nature ("Life, Its Nature, etc.” pp. 23, 24) : " That life does not necessarily imply organization or repro- duction is shown in what may without impropriety be called the Life of the World. Doubtless, there is an impassable chasm between the mineral and the vegetable, as between the vegetable and the animal, and between the animal and man. But this inorganic nature, which is represented as ' dead,’ because it has not the same life with the animal or plant, is it then, to quote Guyot, destitute of all life? It has all the signs of life, we cannot but confess. Has it not motion in the water which streams and murmurs on the surface of the continents, and which tosses in the waves of the sea? Has it not sympathies and antipathies in those mysterious elective affinities of the molecules of matter which chemistry investigates ? Has it not the powerful attractions of bodies to each other which govern the motions of the stars scattered in the immensity of space, and keep them in an admirable harmony ? Do we not see, and always with a secret astonish- ment, the magnetic needle agitated at the approach of a par- ticle of iron, and leaping under the fire of the Northern Light ? Place any material body whatever by the side of another, do they not immediately enter into relations of interchange, of molecular attraction, of electricity, of magnetism? In the inorganic part of matter, as in the organic, all is acting, all is promoting change, all is itself undergoing transformation. And thus, though this life of the globe, this physiology of our planet, is not the life of the tree or the bird, is it not also a life? Assuredly it is. We cannot refuse so to call those lively actions and reactions, that perpetual play of the 194 THE DEVELOPMENT OF LIFE. forces of matter, of which we are every day the witnesses. The thousand voices of nature which make themselves heard around us, and in so many ways betoken incessant and pro- digious activity, proclaim it so loudly that we cannot shut our ears to their language.” Though the above extracts indicate that Grindon and Guyot believed, in certain respects, that there are manifesta- tions like those called living in inorganic matter, yet they by no means intend to imply that the life of men, plants and minerals is the same ; for Grindon further says, p. 24: "Indeed the life of the soul, or that which is played forth as the activity of the intellect and the affections, is the highest expression of all. Compared with this life, the life of ani- mals and plants, and the life of the globe, are but mimicries and shadows.” Grindon calls what is usually termed Life, " physiological life ; ” but when he attempts to account for the origin of life he says (p. 29) : "God is the only independent existence, and He is the cause of all causes. He alone has life in him- self.” And on p. 40 he further says : "Inorganic life, the first named of these three great varieties or manifestations of the vitalizing principle, has been illustrated in the preceding chapters. It will suffice to add here that it has nothing in common with organic or physiological life, much less with the spiritual; nothing, that is to say, except the Divine origin and sustentation.” We shall soon see to what errors the following out an assumed theory may lead us. As before quoted, Hasckel says (p. 23, vol. 1, "History of Creation”) : " When in a solu- tion of salt a crystal is formed, the phenomenon is neither more nor less a mechanical manifestation of life than the HiECKEL’S PHILOSOPHY. 195 growth and flowering of plants, than the propagation of animals or the activity of their senses, than the perception or the formation of thought in man.” Though this extract does not, in so many words., state that the quality of life in minerals, plants and animals is the same, yet the idea seems to be that as the mechanical actions in minerals and plants are alike, or very similar, the vital properties are also alike. In this view of life Haeckel’s philosophy is strikingly simi- lar to that of vai’ious savage tribes. For instance, the Zuni Indians are said to believe that all motion reveals a sign of life; hence, behind the swaying branches of trees and the rolling of waves on the waters, they recognize a living personality, or life, as the cause of these motions, I have before stated that in animals and plants the nutriment goes from outside to inside by a motion peculiar to life, and entirely dissimilar to the formation of crystals; and, when this nutriment has been used, the waste in animals goes, by a peculiar motion, from inside to outside, and this action is continuous. Crystals grow by the aggregation of crystalline particles lodging on the outside, which forms them into particular shapes, and so long as the crystals do not dissolve or decompose, no action or change of place occurs in these particles. The growth is so unlike living growth that for a sane man to assert that they are governed by the same principles seems very strange. The act of crystallization cannot justly be called a living action. There are some, however, who clutch at a statement like the above, viz., that organic and inorganic matter are equally living, and receive it as profound truth. This class of philosophers, or rather speculators in science, has existed since early historic times. Some have done much to stimulate inquiry, and thus sharpen 196 THE DEVELOPMENT OF LIFE. the intellect through its effort to separate truth from error and fact from fiction. Briefly stated this philosophy amounts to this : That life is merely an adjustment of relations, and that the difference be- tween the living and non-living is one of degree, but not of kind ; that life, to some extent, inheres in everything, or in every material substance; and that the action of the heart as well as the circulation of the blood is only an exhibition of mechanical force just as really as the operations of a steam-engine; and that the original driving forces are one and the same. But such do not seem to consider that the steam-engine may be stopped, and take a lengthened rest, and then be started up again without any detriment to its powers. Not so with the action of the heart. When that has once fairly ceased its action that action is never resumed ; when it has once really ceased to beat for five consecutive minutes its action has forever ceased. We know that there is a mechanical action of the heart; but there is a vital prin- ciple behind its normal action. Materialists may deny the existence of this vital principle ; but mere denial has no real force. Badcliffe (as quoted by S. Billing, " Scientific Materialism,” p. 13) says, "We can only suppose that the vital fact exemplifies its energy by physical means in its application to the animal economy. Whatever be the physics of the mechanism, they can but be conducted by waste. The vital energy using them as its methods repairs the waste, and thus excludes all idea of physical force (per se) being the initiatory impulse. "If vital action resulted alone in mechanical motion it might be said that muscular force was physical force; but no physical force reproduces itself.” WHENCE IS LIFE? 197 If physical force could reproduce itself, we might easily solve the problem of perpetual motion. From a great multitude of facts gathered, and inferences deduced from investigation, Haeckel weaves what to him and many others seems a beautiful web of truth. But he has taken premises in the unknown, and hence is likely to err, because he does not know whether or not the principles on which he has built his foundations are resting upon absolute truth. His followers (and they are legion) contend that there was originally in matter itself the power to originate life. This theory dispenses with the necessity of a Creator ; for, if matter is eternal, and has in itself the power to originate life, then there would not appear to be any necessity for a self-existent life (which was originally independent of matter) to cause the manifestations of life which we see in matter. Geologists state that the earth, during its early existence, was so hot that no life could exist on it. It was then simply dead matter, though later on plant life existed when no animal could live. But life, both plant and animal, now exists. Whence did this life come ? How did it spring into existence? Did the dead matter of the earth, in itself, have power to originate life? In other words, did that which was dead have power to bring into existence what it did not itself possess, viz., life? If it did, did it not create some- thing out of nothing? But the philosophic maxim is, ''From nothing, nothing comes.” There seems no way to obviate this difficulty, without acknowledging a Creator, except to assume that all natural bodies are equally living; and thus at the time when we suppose the earth was simply dead matter it was not so, but that the life-giving power was already there. What 198 THE DEVELOPMENT OF LIFE. warrant is there for such an assumption? On the contrary, did not a vital principle move on this dead matter, and trans- form inorganic matter into organic, or living matter? It has been stated that Liebig assumed that dead matter can produce fermentation ; but, as Tyndall well says : " With Liebig, fermentation was by no means synonymous with life. It meant, according to him, the shaking asunder by chemical disturbance of unstable molecules. Does the life of our flasks, then, proceed from dead particles? If my co-inquirer should reply 'Yes,’ then I would ask him, 'What warrant does Nature offer for such an assumption ? Where, amid the multitude of vital phenomena in which her operations have been clearly traced, is the slightest countenance given to the notion that the sowing of dead particles can produce a living crop?’” (p. 296, "Floating Matter.”) No one has yet clearly described the line that separates life from death ; hence, in this case, even with the most learned, analogy and common-sense must be strong witnesses. When we take into consideration the facts which we have before stated, and which seem to show that life is the cause of organization, we must conclude that life had its original beginning in some power outside of and above mere matter. To say that life was originally evolved by chemical processes which occurred during the long ages while the earth was cooling is a mere supposition, for there are no known facts to substantiate that statement. Light, heat, electricity and moisture are mighty instru- mentalities, and, operating on organic matter, produce great and beneficent changes, and also great modifications of the O 7 JD forms of life. But to produce modifications is one thing, and to produce a new creation is quite another. There must have been a beginning somewhere or somehow, and the MICROSCOPIC OBSERVATIONS. 199 reasoning mind wants more than guesswork to satisfy it in its inquiries. The germs of life are everywhere ; in the air we breathe, in the dust beneath our feet, and in the depths of the sea. Where did these germs of life come from ? Living animals only one ninety-thousandth of an inch in diameter can be seen; but who can tell how much smaller living creatures there may be which cannot be seen with the microscope? As Nature is infinite in extension, so she may also be in minuteness. Infusions of hay, and of turnip, and of a score of other articles, have been boiled, with the intent of destroying all life contained in them. These infusions were put in glass bottles, and hermetically sealed ; but in a few days they were found teeming with living organisms. Where did these organisms come from? From a great number of like experiments, made on both sides of the Atlantic, some learned men came to the conclu- sion that these living beings came by " spontaneous genera- tion,” or (perhaps more properly expressed) that this new life was evolved from dead matter, and that new life is being now constantly evolved by the power of nature alone. So extensive and various have these experiments been that it is not safe to turn these trials, tests, and conclusions off without consideration. It is with pleasure, however, that I can say that the labors of M. Pasteur, a French chemist, and of Prof. Tyndall, aided by experiments of other able and careful scientists dur- ing the past fifteen years, have almost entirely revolutionized what was the commonly received scientific opinion twenty years since in regard to this theory of " spontaneous genera- tion ; ” and the germ theory of life, which was once opposed 200 THE DEVELOPMENT OF LIFE. by nearly the whole force of chemical authority, is now as generally accepted as it was formerly rejected ; or, according to Dr. Carpenter, it is now accepted by all, " except a few irreconcilables.” We have not been informed where these life-germs origi- nally came from, or how they were originated. The germ theory destroys the doctrine of " spontaneous generation,” but it does not tell us how* or when the floating germs in the air were placed there, or how life happens to be in the germs. This simply places the originating power one step farther back. But let us see whether our germ theory will help us get life into hermetically sealed bottles after all previous life has been destroyed by boiling. If life cannot be sponta- neously generated, can it be that all life above a certain stage of development may be destroyed by boiling, while the original invisible germs of life are not destroyed ? Can these germs, still retaining their vitality through the boiling, afterwards become developed into visible living organisms ? Germs of life are indeed wonderful things; they consist of many varieties, for each kind is believed to start a life of its particular kind only. I cannot think these germs start one kind or species of life, and then evolve themselves into another species. Not only germs for propa- gation of healthy animal life exist, but disease-germs, which, though living, tend to destroy animal, and even plant life ; and each kind of these germs is distinctly different from every other kind. Different kinds of disease-germs never intermingle, but always breed diseases of their own peculiar kind, typhoid- fever germs do not breed small-pox, nor small-pox breed measles, nor measles, diphtheria. PROF. TYNDALL. 201 Prof. Tyndall says (p. 41, "Floating Matter ”) ; "From their respective viruses, yon may plant typhoid-fever, scar- latina, or small-pox. What is the crop which arises from this husbandry? As surely as a thistle rises from a thistle seed, as surely as the fig comes from the fig, the grape from the grape, the thorn from the thorn, so surely does the typhoid virus increase and multiply into typhoid- fever, the scarlatina virus into scarlatina, the small-pox virus into small-pox. What is the conclusion that suggests itself here ? It is this : That the thing which we vaguely call a virus is, to all intents and purposes, a seed. Excluding the notion of vitality, in the whole range of chemical science you cannot point to an action which illustrates this perfect parallelism with the phenomena of life, this demonstrated power of self-multiplication and reproduction. The germ theory alone accounts for the phenomena.” As germs in grain always develop into stock and grain of their own peculiar kind, so all germs, whether good or evil, develop into their own kinds. But another question now arises. Can germs of living animals or plants pass through materials through which disease germs cannot pass? Disease-germs may be destroyed by carbolic acid and other disinfectants ; but can the original, invisible germs of life (if such exist) be thus destroyed? I now propose, in the next few pages, to go outside of the proper domains of scientific demonstrations. If the following brief suggestions seem puerile, let the wisest answer the questions if he can. These suppositions are not introduced because it is necessary to resort to such hypotheses to dispose of the doctrine of " spontaneous gen- eration,” but they show that, even if we could not filter out all the life-germs (which, luckily, we can), the doctrine of 202 THE DEVELOPMENT OF LIFE. "spontaneous generation,” with all the evidence which has been produced in its favor, would fail of anything like dem- onstration. Is there an original and invisible principle of life which is indestructible? Are immaterial essences connected with the minute material germs? and, if so, how large are they? If the original germs are wholly material, are they larger than what are supposed to be the ultimate and indivisible atoms of matter? Of course, what can be filtered out may be a thousand times larger. Do invisible vivifying influences, or vital forces, which are immaterial, or spiritual, exist prior to the material germs or substances from which animals or vegetables are generated or developed, and cause the animal or vegetable life to spring into existence? And if so, can any material substance inter- fere to hinder the free passage of the spiritual or vital forces to any place where suitable conditions for development exist? Is not Evolution itself dependent upon the action of imma- terial forces? Of course, a thing immaterial (if such exists) must become connected with a material substance before we can have any knowledge of it through our senses. A pain or emotion may be immaterial; but we can have no knowledge of it, except through our physical system. It is probable that pains, thoughts and emotions (though in themselves immaterial) are accompanied by molecular action upon or within the nervous system, and that this very action results in the consciousness of pain, joy, or sorrow and other emotions, and yet there is doubtless something antecedent to these molecular actions ; and the agitation of these molecules may be simply an accompaniment of some mysterious and invisible agency which causes mental states of fear, joy, hope, etc., and also bodily feelings of pain, etc. SIDNEY BILLING. 203 There may be a vital principle of which we can have no knowledge before it becomes connected with the living or- ganisms ; but lack of definite knowledge on this point does not indicate that such a vital principle does not preexist. There are phenomena connected with animal life that I cannot account for except upon the supposition that a vital principle is preexistent. Sidney Billing says (p. 16, "Scientific Materialism”): "If we collate the facts, what do we find? Vital force as the inherent fact of all things ; physical or material force but a consequence of the organization. Vital force origi- nates, physical force acts only through an impulsion. Vital force congregates, disintegrates, and multiplies itself; physi- cal force acts only in masses through gravitation. Vital force cannot be originated, nor its issues directed ; but physi- cal force may be directed and called into action at will, and may be made the plaything of the hour, as the incitation of muscular elasticity after death.” Now about the generation of life in hermetically sealed vessels. From all the evidence pro and con, it seems clear that no life appears in any solution where life germs have been fully destroyed, unless the solution in some way comes in contact with the air, through some want of care in making the experiment, or by some defect in the testing apparatus, or unless it comes in contact with some other substance containing the life-germs ; for the thousand experi- ments made by Prof. Tyndall with various solutions in moteless air, and no life appearing, would seem to settle the question against " spontaneous generation ” in such solutions. But even if his experiments had turned out otherwise, and life had appeared in hermetically sealed vessels after all proper precautions had been taken, that would not 204 THE DEVELOPMENT OF LIFE. necessarily prove the doctrine of ” spontaneous genera- tion.” Suppose the original atoms touch each other in glass, or in dense metals, and that, according to the general forms of matter as found in drops of water and the planets, these atoms are globular, interstices between the atoms must still exist, as in a case of shot, however fine. How then do we know, even in this case, that the interstices between ulti- mate atoms are not large enough to allow the essential or vital principle of life to pass through ? It has been stated that by the action of electricity particles of gold have been driven into plates of glass, which (if true) seems to indicate that what we call solid glass is, in reality, porous, and this would seem to agree with the atomic theory ; and further, that the atoms of gold are fine enough to enter these pores of glass, and that without any supernatural influences. While , as before stated, there is no necessity for resorting to such a hypothesis, we may say that the essential, spiritual life germs, if such can be assumed to exist, may be, for all that we know, as many times smaller than the atoms of gold as atoms of gold are times smaller than bullets. No one can show that this may not be so. Then again, suppose that these ultimate atoms, which no man ever saw, were of irregular shape, interstices may exist even larger than if all were globular, and thus the porosity of the substance be even greater than in the former sup- posed case. That interstices must exist is an inevitable consequence of the atomic theory as generally received. Thus these experiments of learned men in Europe and America,— with these infusions of hay, and of turnip, and a dozen other infusions, both animal and vegetable, in sealed RUDOLF SCHMID. 205 bottles, even if life was apparently generated there, would by no means prove that an immaterial principle of the germs of life did not go through the pores of the glass into these infusions. Ido not claim that this is so ; but it shows that what some learned men have received as a demonstration falls very far short of it. Since writing the above I have seen Rudolf Schmid on " The Theories of Darwin,” and on pp. 138, 139 find the following: " This inexplicability would still exist, if what is quite improbable should happen, namely, that the experi- mental attempts at artificially producing organic life should be successful, and if thus the question as to the gen- eratio cequivoca, which during the past decades so much alarmed the minds of scientists and theologians, should be ex- perimentally solved and answered in the affirmative. For in view of the hopes of a possible explanation of life, which is expected to be the reward for the success of these attempts, Zollner is fully right in saying: ' That the scientists to-day set such an extremely high value on the inductive proof of the generatio cequivoca, is the most significant symptom of how little they have made themselves acquainted with the first principles of the theory of knowledge. For, suppose they should really succeed in observing the origin of organic germs under conditions entirely free from objection to any imaginable communication with the atmosphere, what could they answer to the assertion that the organic germs, in refer- ence to their extension, are of the order of ether-atoms, and, with these, press through the intervals of the material mole- cules which form the sides of our apparatus ? ’ ” Doubtless the reader already knows that the atomic theory is merely an hypothesis, and that we do not know whether the atoms (if they exist) are all alike and material, or 206 THE DEVELOPMENT OF LIFE. whether a part are material atoms and others ether-atoms. Again, among the sixty-five supposed original chemical ele- ments, what, for instance, is the difference between an atom of hydrogen and one of nitrogen ? So of the various kinds of life-germs which we are able to screen out of fluids, in what do their differences consist? Where these life-germs originate, or how they happen to be everywhere present, Ido not attempt to explain. But it has been proved by Pasteur’s and Tyndall’s experiments that these life-germs, so far as we are now acquainted with them, can easily be prevented from getting into solutions by wads of cotton-wool. Sometimes, however, it has been exceedingly difficult to so perfectly filter infusions that all the visible suspended par- ticles of matter will be removed. After going through a score or more sheets of filtering-paper, visible particles will still re- main. Yet porous earthen-ware will screen out such life- germs ; and thus we have no need of laying much stress upon any supposed spiritual essence which may go through what are called solids. Dr. Tyndall says (pp. 80, 81, "Floating Matter”): "Infinitesimal as these particles are, however, they may be separated by mechanical means from the liquid in which they are held in suspension. Filters of porous earthen-ware, such as the porous cells of Bunsen’s battery, have been turned to important account in the researches of Dr. Zahn, Prof. Klebs, and Dr. Burdon Sanderson. " In various instances it has been proved that, as regards the infection of living animals, the porous earthen-ware inter- cepts contagia. For the living animal, organic infusions or Pasteur’s solution may be substituted. Not only are ice- water, distilled water, and tap-water thus deprived of their powers of infection, but, by plunging the porous cell into OWEN AND HITCHCOCK. 207 an infusion swarming with Bacterial life, exhausting the cell, and permitting the liquid to be slowly driven through it by atmospheric pressure, the filtrate is not only deprived of its Bacteria, but also of those ultra-microscopic germs which appear to be as potent for infection as the Bacteria them- selves The precipitated mastic particles before described, which pass unimpeded through an indefinite number of paper filters, are wholly intercepted by the porous cell. "These germinal particles abound in every pool, stream, and river. All parts of the moist earth are crowded with them. Every wetted surface which has been dried by the sun or air contains upon it particles which the unevaporated liquid held in suspension. From such surfaces they are detached and wafted away, their universal prevalence in the atmosphere being thus accounted for. Doubtless they some- times attach themselves to coarser particles, organic and in- organic, which are left behind along with them ; but they need no such rafts to carry them through the air, being themselves endowed with a power of flotation commensurate with their extreme smallness and the specific lightness of the matter of which they are composed.” Prof. Owen, as quoted by Hitchcock (p. 304), more than thirty years since wrote : " Thus each leaves, by the last act of its life, the means of perpetuating and diffus- ing its species by thousands of fertile germs. When once the thickly tenanted pool is dried up, and its bottom con- verted into a layer of dust, these inconceivably minute and light ova will be raised with the dust by the first puff of wind, diffused through the atmosphere, and may there re- main long suspended, forming, perhaps, their share of the particles which we see flickering in the sunbeam, ready to fall into any collection of water, beaten down by every 208 THE DEVELOPMENT OF LIFE. summer shower into the streams or pools which receive or may be formed by such showers, and, by virtue of their tenacity of life, ready to develop themselves whenever they may find the requisite conditions of their existence. The possibility, or, rather, the high probability, that such is the design of the oviparous generation of the infusoria, and such the common mode of the diffusion of their ova, renders the hypothesis of equivocal generation, which has been so fre- quently invoked to explain their origin in new-formed natu- ral or artificial infusions, quite gratuitous.” (Owen’s "Lect. Comp. Anat.,” vol. 2, p. 31.) It is doubtless from these very minute floating germs that life in the infusions which have been deprived of all living existences must come. But this still leaves the question how these " germinal particles ” first came to be in every pool, stream, and river unanswered. Science has not demonstrated how these myriad forms of germinal life which constitute so large a proportion of the "floating matter of the air” are themselves generated, or decided whether they are first generated in the water. It is generally thought that the first appearance of terrestrial life was in the water, that in the water living organisms were first created or developed. It is, however, useless to make positive assertions on this pbint, in our present state of knowl- edge. Certainly the advocates of " spontaneous genera- tion” have no warrant for assuming that these animalcules which are so numerous in water are " spontaneously gen- erated” in the water. We do not know for a certainty whether these germinal particles are first in the air and fall into these pools, and in this way fill the pools with living particles, or whether they are first generated in the water, and from these wafted into the atmosphere. Nor is it neces- sary that we should know whether they first originate in the PASTEUR AND TYNDALL. 209 air or in the water, so long as we know the fact that in both air and water these germs exist in almost infinite numbers. The advocates of " spontaneous generation ” have made hundreds, and, perhaps, thousands, of experiments, and some- times have thought they proved it beyond a doubt. One exhausted the air from a glass vessel, and let no air into the vessel except what passed through quicksilver, supposing that no life-germs could go through so dense a medium as quicksilver; but living things appeared in his solution, and he thought he had a case of genuine spontaneous generation. But M. Pasteur, upon investigation, found that quicksilver itself might become permeated with these living germs. I have referred to faultiness of experiments as a frequent cause of misleading the believers in "spontaneous genera- tion,” and I can favor my readers no better than by quoting freely from Prof. Tyndall to show how these mistakes are likely to occur. He says (pp. 124, 125, " Floating Matter”) : the course of this inquiry some eminent biologists have been good enough, from time to time, to look in upon my work, and to give me their views regarding the evidential force of the experiments. To Prof. Huxley, moreover, I am indebted for undertaking the examination of a number of the hermetically sealed tubes. Thirty of them were placed in his hands, none of them being regarded as defec- tive. A close examination, however, disclosed in one of them a mycelium. No faultiness could for a time be dis- covered in the tube; the sealing appeared to be quite as perfect as that of its sterile fellows. " Once, however, on shaking it, a minute drop of liquid struck my friend’s face, and he soon discovered that an orifice of almost microscopic minuteness had been left open in the nozzle of the tube. Through this the common air 210 THE DEVELOPMENT OF LIFE. had been sucked in as the liquid cooled, and hence the con- tamination. It was the only defective tube of the group of thirty, and it alone showed signs of life. " The statement of this fact before the Royal Society, by Prof. Huxley, brought to my mind a somewhat similar experience of my own. One morning in November I lifted one of the hermetically sealed tubes from the wire on which it was suspended, and, holding it up against the light, dis- covered, to my astonishment, a beautiful mycelium at the bottom. Before restoring the tube to its place I touched its fused end, and found it cutting sharp. Close inspection showed that the nozzle had been broken off; the common air had entered and the seed of the mycelium had been sown. Two other instances, one like that observed by Prof. Huxley, have since come to light. In one of them a minute orifice remained after the supposed sealing of the tube. The other case was noticed when the tubes were returned from the Turkish bath. One of them contained a luxuriant mycelium. It was noticed that the liquid in this tube had singularly diminished in quantity, and on turning the tube up it was found cracked at the bottom. 'f No case of pseudo-spontaneous generation ever occurred under ray hands that was not to be accounted for in an equally satisfactory manner.” Much more might be written on this point, but the ex- amples here given are samples of hundreds of like experiments with like results. But I will add one more quotation from Tyndall (p. 224, "Floating Matter ”). He says, "The source of the contagium was also indicated by the following experi- ments. "A large number of retort-flasks, embracing infusions of snipe, wild duck, partridge, hare, rabbit, mutton, turbot, TYNDALL 211 salmon, whiting, mullet, turnip, and hay, had remained over from my stock of 1875. After a year’s exposure to the temperature of our warm room not one of these flasks showed the slightest trace of turbidity or life. On the 7th of December the sealed ends of forty of them were snipped off in the laboratory. Five days afterwards twenty-seven of them were found swarming with organisms, a consider- ably higher percentage than that obtained by the same pro- cess in the same laboratory a year previously. "It is needless to dwell with any emphasis on the obvious inference from all this, namely, that the contagium is external to the infusions, that it is something in the air, and that at different times we have different amounts of aerial interspace free from the floating contagium.” It would seem that these experiments ought to settle the question. When a writer has won a high reputation for careful scientific investigations his statements will justly have great weight; and when his experiments seem to demonstrate the truth of a theory, then the majority of men will believe that he has made no mistake in his conclusions; yet when no one can know with certainty what the actual truth is in a disputed case like the origin of life, great men may support a wrong theory as well as men of less eminent attainments. Careful students who have clear heads are quite as likely to hold actual truth as men of genius who deal largely in theories which are the creations of their own imaginations. The writings of great men prove this, for they are largely composed of articles correcting the mistakes of still greater men. Huxley says ("Critiques and Addresses,” p. 281) : Dr. Haeckel "conceives that all forms of life originally com- 212 THE DEVELOPMENT OF LIFE. menced as Monera, or simple particles of protoplasm, and that these Monera originated from not-living matter. Some of the Monera acquired tendencies towards the Protistic, others towards the Vegetal, and others towards the Animal, modes of life. The last became animal Monera Then these animal monera went through twenty-two dis- tinct stages, till the perfect man was produced. But no proof, beyond certain statements and suppositions which appear reasonable to Hheckel, is given. As it seems so to him, and no man has proved that he is not right in many of his suppositions, —he has a right to his own opinions; and so have other men, who cannot accept his conclusions, a right to their opinions. Dr. Wainwright, in opposing the views of Haeckel (pp. 77, 78, "Scientific Sophisms ”), states that "Du Bois Rey- mond has incurred the . . . wrath of Haeckel by declaring this genealogical tree (Stammbaum) to be as authentic in the eyes of a naturalist, as are the pedigrees of the Homeric heroes in those of an historian.” Haeckel is more positive in his statements than most men of such high intellectual attainments usually are. Generally when really great men propound such or similar theories they do not pretend that they can demonstrate them to be true. They propose- them as conclusions which should be drawn from other facts which they know to be true. If these hypotheses seem reasonable to a majority of scientific men they are generally accepted without actual demonstra- tions. But trouble comes when second or third rate men (claiming to be scientific) read these hypotheses and then restate them as facts which have been proved, and thus mislead those who listen to them. So long as we carefully distinguish between facts and mere suppositions we are not PROTOPLASM. 213 in danger ; but when we mistake suppositions for facts then danger comes. Let us then consider facts, and see where the boundaries of our knowledge are fixed. First, in regard to the bounda- ries which limit microscopic observation : Much of the matter which floats in our atmosphere is too fine to be seen with the most powerful microscopes, and yet a concentrated beam of light will reveal the presence of these motes. But if these motes are too small for microscopic observation, any accurate description of their shapes or com- position is impossible. Yet many of these very minute motes are believed to be living germs, which breed disease, or parasitic life if they get access to proper material, such as wounds in animals or men. Here are limits to be constantly kept in mind when study- ing matters pertaining to the origin of life. The original germs of life may be much smaller than anything which can be discerned with the microscope. It should also be borne in mind, that, with the microscope, one investigator may see what another can never see. And another man may think he sees what no man ever did see or ever will see. The imagination often supplies investigators with mistaken material. Now about the examination of the smallest and simplest particles of organic matter, viz., pro- toplasm. According to Strieker (Wainwright, "Scientific Soph- isms,” p. 132), protoplasm is many-shaped. "We have club- shaped protoplasm, globe-shaped protoplasm, bottle-shaped protoplasm, cup-shaped protoplasm, spindle-shaped proto- plasm;” and he describes twelve other shaped protoplasms. Sometimes it is fluid, sometimes semifluid and gelatinous ; sometimes of considerable resistance. 214 THE DEVELOPMENT OF LIFE. " Then there is nerve protoplasm, brain protoplasm, bone protoplasm, muscle protoplasm, and the protoplasm of all the other tissues, no one of which but produces its own kind, and is uninterchangeable with the rest.” Lastly, "We have to point to the overwhelming fact that there is the infinitely different protoplasm of the various infinitely different plants and animals, in each of which its own protoplasm, as in case of the various tissues, but produces its own kind, and is un- interchangeable with that of the rest.” Query: Are these protoplasms really different in kind, or is the difference in the moulding forces ? The protoplasm from which the sugar-maple is developed and that from which the deadly nightshade grows may be entirely different protoplasms ; and this may be the reason why each never gets the protoplasm which belongs to the other. Why do weeds in the garden always draw from the soil only their own kind of protoplasm? Why does wheat always draw only its own kind, while the grass draws another kind? Why do differ- ent kinds of grasses never interchange their own kinds? Does it not seem probable that there may be a different kind of vital principle for each and every species of plant and ani- mal, which transmutes the same or similar kinds of proto- plasm, so as to make them contribute to the support and growth of each different species of plants and animals ? This action of growth seems to be mechanical; but under what law of mechanics do they make this choice of substance, and never make a mistake in their choice ? So of animals. There is a certain something which places a clear distinction between the building up of men and animals, and also between the different races of animals. There is no danger that horses will ever assimilate the protoplasm belonging exclu- sively to sheep, nor that sheep will ever produce dogs, nor SINGLE CELLS. 215 dogs produce birds. Nature has fixed these bounds, and never mistakes them. From the fact that the first outlines of human beings and all other animals in the ovum appear precisely alike, and cannot be distinguished from each other, and that each is a single cell, certain evolutionists carrying out analogy assert that the original ancestral form of man and all other animals was a one-celled organism. But it is legitimate to ask such to show proof of the correctness of this assertion. The word cell is here used not to represent the ultimate particles of protoplasm but the elementary forms of organic matter somewhat in mass. A cell generally consists of con- centric layers of cell-wall, protoplasm, etc., in one distinct organism. The ovum is a single cell before fertilization, but fertiliza- tion entirely changes the character of the ovum, as it after- wards becomes a many-celled organism, and the number of cells continues to increase with its development. Dr. Haeckel says (pp. 136, 137, vol. 1, "Evolution of Man’’) : " Even under the highest magnifying power of the best microscope, there appears to be no essential difference between the eggs of Man, of the Ape, of the Dog, etc. This does not mean that they are not really different in these dif- ferent Mammals. On the contrary, we must assume that such differences, at least in point of chemical composition, exist universally. Even of human eggs, each differs from the other. In accordance with the law of individual variation, we must assume that 'all individual organisms are, from the very beginning of their individual existence, different, though often very similar.’” I am somewhat surprised at this confession of Dr. Hfeckel, for I should suppose that, to be consistent with his general 216 THE DEVELOPMENT OF LIFE. theory, he would have contended that these ova, which originally looked alike, were, indeed, alike at first, but that all the differences manifested afterwards by different races of animals were simply modifications received from the particular animals through which they received their development. It is probable, however, that the Doctor looked farther, and saw what effect this theory of original individual differences would have in another direction. Sure enough, why should there not be individual differences from the very beginning of life ? But where is this beginning ? Certainly it is before the ovum gets to be a one-hundred- and-fiftieth of an inch in diameter, as it is generally, when examined with the microscope. Probably at this time it has thousands, and, perhaps, millions, of molecules in its organism; and the innate composition of the ova of the man, dog, horse, etc., may be as different as the hundreds of chemical combinations, which can be made from a few simple chemical constituents, some of which combinations, as water, may be perfectly harmless; while others, like sulphuric acid, gunpowder, or corrosive sublimate, may be peculiarly destructive. So the differences of the very natures which are contained in these eggs which look alike may be originally as great as we find them in adult men, dogs, and horses. The original natures inhere in the ova, and we have no reason to suppose that the differences in their original natures are not as real in these ova as they are in the mature animals. THE ORIGIN OF LIFE. 217 CHAPTER IX. THIS CHAPTER CONTAINS A SHORT HISTORY OF DISCUSSIONS CONCERNING THE SUBJECTS CONSIDERED IN THE LAST CHAPTER, AND EXTRACTS FROM THE RECORDS OF EX- PERIMENTS MADE BY PROF. TYNDALL UPON GERMI- NATING FLUIDS. The writings of Aristotle generally controlled the science of natural history for two thousand years, and in fact Aristotle may be called "the Father of Natural History.” Aristotle denied " the eternity of the individual,” and con- tended that the individual came into existence "in the act of generation, and perished at death.” But if Aristotle was right in this supposition, of which he gave no proof, that does not answer the question, " Whence is life?” For two thousand years succeeding Aristotle the doctrine of " spontaneous generation ” was generally accepted by scientific men. Caterpillars and insects which infest trees and vegetables were supposed to be spontaneously gen- erated. Because putrefying flesh was infested with worms, or other living creatures, the supposition was that these came spontaneously. No one was able to show that this was other- wise until A.D. 1668, when Dr. Francisco Redi, of Tuscany, while watching meat ready to decay noticed flies alight upon it, and suspected that the maggots which followed were in some way connected with these flies. He then placed meat in jars so covered that the flies could not get access to it, and found that, although it putrefied, no maggots came. He 218 THE DEVELOPMENT OF LIFE. then put gauze over the mouth of the jars, and he found that the flies hovered over the meat, and laid their eggs on the gauze, and they hatched out there, but no maggots came in the meat. Other physicians and philosophers continued these observations and experiments ; and though improve- ments in the microscope helped to dispel the illusions of centuries respecting the generation of the larger insects, etc., yet the animalcules found in stagnant water were still believed to be spontaneously generated. For about two hundred years succeeding, many distinguished men were ranged on each side of the controversy, and not until within the past twenty years have anything like positive results been reached on this question. As late as 1872 Dr. H. C. Bastian published his views on abiogenesis, and strongly advocated the doctrine of "spontaneous generation.” Speculations concerning the origin of bacterial life become intimately connected with the germ theory of diseases. Do diseases originate themselves ? or are they propagated as vegetable and animal life are propagated? Do putrefac- tive germs breed from previous germs ? Or do they originate spontaneously? Closely connected with the germ theory comes the "antiseptic system of surgery” of Prof. Lister, which has rendered surgical operations comparatively safe which, a few years ago, were exposed to extreme peril. Prof. Lister, like Pasteur, Dr, Budd, Prof. Tyndall, and others, believes that all putrefactive diseases originate from disease- germs which float in the air and readily attach themselves to any person or substance which is susceptible to their action. Dr. W. B. Carpenter writes, in the " Nineteenth Century,” of Prof. Lister’s theory (as quoted in "Popular Science Monthly,” Dec., 1881, p. 248) : " Among the most PASTEUR AND DR. CARPENTER. 219 immediately productive of its results may be accounted the ' antiseptic surgery ’ of Prof. Lister, of which the principle is the careful exclusion of living bacteria and other germs alike from the natural internal cavities of the body and from such as are formed by disease, whenever these may be laid open by accident or may have to be opened surgically. This exclusion is effected by the judicious use of carbolic acid, which kills the germs without doing any mischief to the patient; and the saving of lives, of limbs, and of severe suffering, already brought about by this method, constitutes in itself a glorious ti’iumph alike to the scientific elaborator of the germ-doctrine and to the scientific surgeon by whom it has been thus applied.” M. Pasteur has cultivated various disease-germs as one would cultivate grain, and has discovered processes by which these germs may be rendered malignant, and in almost every case produce certain death to such as become inoculated with the deadly virus; and he has also discovered Avays of render- ing the same comparatively harmless. His experiments have been of immense advantage in stamping out deadly diseases among the flocks of France. He has also discovered the destroyers of the grape-vine of France. He proved them to be propagated by living germs, and provided a remedy against them. The remarks of Dr. Carpenter are so directly in point and of such practical importance that I shall quote freely from his article. He says of the transmission of disease- germs among flocks of sheep : " One of the first questions examined by Pasteur was the cause of outbreaks of ' char- bon’ in its most deadly form among flocks of sheep feeding in what appeared to be the healthiest pastures, far removed from any obvious source of infection. Learning by the in- 220 THE DEVELOPMENT OF LIFE. quiries he instituted that special localities seemed haunted, at distant intervals, by this plague, he inquired what had been done with the bodies of the animals that had died of it, and learned that it had been customary to bury them deep in the soil, and that such interments had been made, it might have been ten years before, beneath the surface of some of the very pastures in which the fresh outbreaks took place. Not- withstanding that the depth (ten or twelve feet) at which the carcasses had been buried seemed to preclude the idea of the upward travelling of the poison-germs, the divining mind of Pasteur found in earthworms a probable means of their conveyance, and he soon obtained an experimental veri- fication of his idea which satisfied even those who were at first disposed to ridicule it. Collecting a number of worms from these pastures, he made an extract of the contents of their alimentary canals, and found that the inoculation of rabbits and Guinea-pigs with this extract gave them the severest form of ' charbon,’ due to the multiplication in their circulating current of the deadly anthrax-bacillus, with which their blood was found after death to be loaded. " Another mode in which the disease-germs of anthrax may be conveyed to herds of cattle widely separated from each other and from any ostensible source of infectioh was discovered by the inquiries prosecuted, a few years ago, by Prof. Burdon-Sanderson at the Brown Institution, in conse- quence of a number of simultaneous outbreaks which occurred in different parts of the country. It was found that all the herds affected had been fed with brewers’ grains, supplied from a common source ; and, on examining micro- scopically a sample of these grains, they were seen to be swarming with the deadly bacillus, which, when it has once PASTEUR AND DR. CARPENTER. 221 found its way among them, grows and multiplies with extraordinary rapidity.” Pasteur and others struck upon the idea that the violence of such diseases might be mitigated by inoculation, in the same way that inoculation against small-pox has been prac- tised. Having cultivated charbon-virus until it was of proper strength, he tried it upon various animals with suc- cess, until the Provincial Agricultural Society of France thought best to make a test of the value of his theory upon a scale of considerable extent. The result is described as follows in the language of Dr. Carpenter : "Accordingly, a farm and a flock of fifty sheep having been placed at M. Pasteur’s disposal, he 'vaccinated’ twenty-five of the flock (distinguished by a perforation of their ears) with the mild virus on the 3d of May last, and repeated the operation on the 17th of the same month. The animals all passed through a slight indisposition, but at the end of the month none of them were found to have lost either fat, appetite, or liveliness. On the 31st of that month all the fifty sheep, without distinction, were inoculated with the strongest charbon-virus, and M. Pasteur predicted that on the following day the twenty-five sheep inoculated for the first time would all be dead, while those protected by previous ' vaccination ’ with the mild virus would be perfectly free from even slight indisposition. A large assemblage of agricultural authorities, cavalry offi- cers, and veterinary surgeons having met at the field the next afternoon (June 1), the result was found to he ex- actly in accordance with M. Pasteur's predictions. At two o’clock twenty-three of the 'unprotected’ sheep were dead; the twenty-fourth died within another hour, and the twenty-fifth, an hour afterward. But the twenty-five 222 THE DEVELOPMENT OE LIFE. 'vaccinated’ sheep were all in perfectly good condition; one of them, which had been designedly inoculated with an extra dose of the poison, having been slightly indisposed for a few hours, but having then recovered. The twenty- five carcasses were then buried in a selected spot, with a view to the further experimental testing of the poisonous effect produced upon the grass which will grow over their graves. But the result, says the reporter of the 'Times’ (June 2) 'is already certain; and the agricultural public now know that an infallible preventive exists against the charbon-poison, which is neither costly nor difficult, as a single man can inoculate a thousand sheep in a day.’ ” To show the extreme importance of this theory in regard to other diseases, I quote further from Dr. Carpenter; " These wonderful results obviously hold out an almost sure hope of preventing the ravages, not merely of the destructive animal plagues that show themselves from time to time among us, but of doing that for some of the most fatal forms of human infectious disease which Jennerian vaccination has already done —as shown by Sir Thomas Watson in these pages for what was once the most dreaded of them, small-pox.” It scarcely seems too much to expect that before long, as Prof. Lister last year suggested, "An appropriate 'vaccine’ may be discovered for measles, scarlet fever, and other acute specific diseases in the human subject; ” for already, as I have been informed by one of the most dis- tinguished of the United States members of our Congress, re- searches have been there made, with very promising results, on the " cultivation of the diphtheritic virus,—the mor- tality from which, in England and Wales, during the last decade, has averaged nearly three thousand annually, being, THE PLAGUE. 223 for seven years, 1873-1879, half as great again as the mortality from small-pox during the same period.” I may here add that M. Pasteur has now secured a world-wide reputation for his successful treatment of the dreadful disease of hydrophobia by means of vaccination. Much more might be said on this point, and its importance will appear more clearly when we consider that the " black death ” which carried off one-third of the population of Europe some five hundred years ago, was, doubtless, prop- agated by disease germs which floated through the atmos- phere. Dried disease germs will live through all extremes of heat or cold ever experienced in our climate, and prob- ably will retain their destructive vitality, if kept dry, for centuries. I see no reason why they may not (like the grain taken out with the Egyptian mummies and planted) grow into a regular crop after lying dormant for thousands of years, during all which time their vitality may remain unimpaired. The plague which has so often afflicted parts of Europe was a sort of contagious fever, accompanied by carbuncles and buboes. The last visitation to Southern Europe was in 1815 and 1816, and we may hope it may never again visit the earth; yet I see no reason why its germs may not still exist, and only favorable circumstances may be wanting to induce its return. Each kind of disease-germs breeds only its own kind, and for each kind of contagious disease a separate class of germs exists; and if these germs are not self-originating, or, in other words, cannot be spontaneously generated, then the question how they do originate assumes great importance. Shultze and Schwann, in Germany, tried many experiments to show the effect of the exclusion of the air in preventing 224 THE DEVELOPMENT OF LIFE. the appearance of living organisms in decomposable fluids. Dr. Carpenter continues : " But the discovery of the real nature of yeast and the recognition of the part it plays in alcoholic fermentation gave an entirely new value to Shultze’s and Schwann’s results, suggesting that putrefactive and other kinds of decomposition may be really due, not (as formerly supposed) to the action of atmospheric oxygen upon unstable organic compounds, but to a new arrangement of elements brought about by the development of germinal particles deposited from the atmosphere. "It was at this point that Pasteur took up the inquiry, and, for its subsequent complete working out, science is mainly indebted to him ; for, although other investigators notably Prof. Tyndall have confirmed and extended his conclu- sions by ingenious variations on his mode of research, they would be the first to acknowledge that all those main posi- tions which have now gained universal acceptance, save on the part of a few obstinate ' irreconcilables,’ have been estab- lished by Pasteur’s own labors. These positions may be briefly summarized as follows : 1. " That no organic fluid undergoes spontaneous fermen- tation or decomposition, even in the presence of atmospheric air, any such action being originated and maintained only by the developmental action of definite organic germs. 2. "That different kinds of fermentation (using that term in its large sense) are produced by organic germs of different species. Thus, while torula sets going the alcoholic fermentation in a saccharine wort, other fungoid germs will set up the acetous, and others, again, the putre- factive, fermentation, when introduced into fluids of the same kind. 3. "That many different kinds of germs —notably those GERM-PARTICLES. 225 of the bacteria, which induce putrefactive fermentation are constantly floating in the ordinary atmosphere, so as to be almost certainly self-sown in any organic fluid freely ex- posed to it. 4. " That, if these germs be removed by mechanical fil- tration, or be got rid of by subsidence, or be deprived of their potency by chemical agents which destroy their vitality, the most readily decomposable organic fluid may be subjected to the freest contact with the air from which the germs have been thus eliminated without undergoing any change. 5. "That as there is no such thing as fermentation with- out the presence of germ-particles, so there is no such thing as the spontaneous origination of such germs, each kind, when sown in the liquid, reproducing itself with the same regularity as in higher plants, and thus continuously main- taining its own type. 6. "That such germ-particles, when dried up, can not only maintain their germinal power for unlimited periods, starting into renewed activity so soon as the requisite con- ditions are supplied, but that, in this state of dormant vitality, they can be subjected to influences which would destroy the life of the growing plants, such as very high or very low temperatures, the action of strong acid or alkaline solutions, and the like.” It will be seen that these statements cover a very wide field. The air we breathe is permeated with fine floating matter, and about one-half of this floating dust is composed of organic matter, the very smallest particle of which may carry the seeds of life or death to organic matter subject to its influences. This has been proved by taking solutions which have been put up in hermetically-sealed vessels, and which have remained perfectly clear, and devoid of the least 226 THE DEVELOPMENT OP LIFE, appearance of life for months ; but by placing the smallest particle of this dust in these infusions, they will teem with living organisms within forty-eight hours. These floating particles, which can be seen by a concen- trated beam of light, are so exceedingly minute that they cannot be seen by the best microscope. In proof of this I quote from Prof. Tyndall’s " Floating Matter of the Air” (p. 78) : "'Potential germs ’ and 'hypothetical germs’ have been spoken of with scorn, because the evidence of the micro- scope as to their existence was not forthcoming. Sagacious writers had drawn from their experiments the perfectly legitimate inference that in many cases the germs exist, though the microscope fails to reveal them. Such infer- ences, however, have been treated as the pure work of the imagination, resting, it was alleged, on no real basis of fact. But in the concentrated beam we possess what is virtually a new instrument, exceeding the microscope in- definitely in power. Directing it upon media which refuse to give the coarser instrument any information as to what they hold in suspension, these media declare themselves to be crowded with particles not hypothetical, not po- tential, but actual and myriad-fold in number showing the 'microscopist that there is a world far beyond his range.” Thus we have in the concentrated beam of light a revealer of what would otherwise forever remain con- cealed. But we must bear in mind that these minute atmospheric germs probably are not the bacteria of disease but simply the germs from which the bacteria are bred. And yet not all these germs are necessarily deleterious in their influences. FLOATING GERMS. 227 All water which is exposed to the common air is per- vaded with these germinal particles, which fall into it from the air, if such germs are not indigenous to the water. From the immense number of germs in a closed room, we might infer that every part of the surface of the water must constantly be becoming filled with them. Tyndall has estimated that in a room fifteen by twenty feet, divided into horizontal spaces six inches apart, the number of germs that fall daily are over 30,000,000. He says: "At all events, 30,000,000 of germs daily would be an exceedingly moderate estimate of the number fall- ing into thirty layers of tubes.” It is true that some are sceptical in regard to this great number of germs, but surely there are enough to infect any and every particle of fermentable or putres- cible matter which is left exposed to the air. These germs may be much more plenty in one place than in another, as was proved by the experiments of Tyndall in 1876, when he found it very difficult to perfectly sterilize infu- sions in a certain room ; but in a shed built only eight yards from this room he found no difficulty in sterilizing them. In the laboratory where he had used some old hay the germs remained very abundant for a long time after- wards ; but the shed built only eight yards distant had not been infected by the hay-germs, and germs were compara- tively few there. Perhaps no one article has more vigorous life-germs in it than old hay, and the infusions are often hard to sterilize. Well may Tyndall say, as he does on p. 179 : "Let us compare results and draw conclusions. At a distance of eight yards from the shed, viz., in the labora- tory, infusions both of beef and cucumber refused to be 228 THE DEVELOPMENT OF LIFE. sterilized by three hours’ boiling. Indeed, I have samples of both infusions which have borne five hours’ boiling and developed multitudinous life afterwards. But the upshot of this experiment in the disinfected shed is, that every tube of the two chambers, though boiled for only five minutes, con- tains an infusion which, at the present hour, is as limpid as the purest distilled water. " What shall we say, then ? Is the infusion in the labora- tory endowed with a generative force denied to the same infusion in the shed? Irrespective of the condition of the air can a linear space of eight yards produce so remarkable a difference ? It is only the confusion of mind still prev- alent in relation to this subject that renders such a ques- tion necessary. Let me add that it suffices simply to wave a bunch of hay in the air of the shed to make it as infective as the laboratory air. Even the unprotected head of my assistant when his body was carefully covered sufficed in some cases to carry the infection.” In some localities high above the sea level meat never putrifies, though exposed to the air and even the sunlight. In some places in the north-western territories of the United States when the settlers kill an ox or a deer they are ac- customed to hang the meat on a tree some twenty feet above the ground, fully exposed to the winds, and it does not putrefy, and why? Doubtless there is nothing to cause putrefactive germs to float so high above the ground. But place meat in a cellar there at the same time and it will putrefy. These germs seem to float near the ground, but not high above it. Edward King states that at the monastery at St. Bernard, in Switzerland, the dead never putrefy. After describing the manner of gaining entrance to the morgue there, and DEATH WITHOUT PUTREFACTION. 229 looking at the dead in the dim light, he writes concerning the first one which attracted his attention as follows (" Boston Journal,” Oct. 9, 1882) : " Pretty soon you discern that the face belongs to the body of a woman, and the woman is clasping to her breast the form of a tiny babe. The mother is seated on the ground, and appears to be dazed by the light pouring down into her darksome habitation. But oh, the horror of her face ! Here is death without decay; here, eight thousand feet above the sea-level, putrefaction is unknown.” Not only in the Alps and among the Rocky Mountains, but wherever the air or insects do not bear putrefactive germs, putrefaction is unknown. Floating disease germs are abundant during the existence of widespread epidemics. A fact which seems to indicate some connection betwe'en disease-germs and bacterial germs may be mentioned in regard to experiments made by Tyndall during the years 1875 and 1876. During the latter part of 1876 epidemics wei’e quite general in London. Tyndall then found it much more difficult to sterilize infusions and keep them sterile than in 1875, when there was a time of general health. This of itself is not proof that these general epidemics, or the germs of these epidemics, were the direct cause of this difficulty of sterilizing the infusions, but the two certainly went together. The germs of contagious diseases are generally minute vegetable organisms ; but similar kinds of organisms pro- duce somewhat different results, or are sometimes modified by their surroundings. If such germs get access to dead animal matter they pro- duce putrefaction; but, if to living animals, they may produce fever or inflammation. Prof. Tyndall says : " A contagious disease may be defined 230 THE DEVELOPMENT OF LIFE. as a conflict between the person smitten by it and a specific organism, which multiplies at his expense, appropriating his air and moisture, disintegrating the tissues, and poisoning him by the decompositions incident to its growth.-’ But as late as 1875, at a meeting of the Pathological Society, Dr. H. C. Bastian admitted the coexistence of bacteria and contagious disease; but, ’'instead of consid- ering these organisms as ' probably the essence or an insep- arable part of the essence ’ of the contagium, Dr. Bastian contended that they were ' pathological products ’ spon- taneously generated in the body after it had been rendered diseased by the real contagium.” (Tyndall, "Floating Matter,” p. 93.) That is, although these germs are always present in zymotic diseases, Dr. Bastian contended that they were the result of the disease, instead of being the cause. In treating diseases it is important to understand whether these bacteria are the cause or the result of the disease; for if they are simply the result of the disease, it is of little avail if we destroy them ; but if they are the cause, it is of immense importance that they, if possible, be destroyed, that through their destruction diseases may be stayed. There can be no putrefaction nor fermentation without these germs, and hence, without them, there can be no dis- eases which are in their nature fermentable or putrefactive. Prof. Tyndall says ("Floating Matter of the Air,” p. 263) : " The most striking analogy between a contagium and a fer- ment is to be found in the power of indefinite self-multipli- cation possessed and exercised by both. You know the exquisitely truthful figures regarding leaven employed in the New Testament. • A particle hid in three measures of meal leavens it all. A little leaven leaveneth the whole lump. CONTAGIUM. 231 "In a similar manner, a particle of contagium spreads through the human body and may be so multiplied as to strike down whole populations. Consider the effect pro- duced upon the system by a microscopic quantity of the virus of small-pox. That virus is, to all intents and purposes, a seed. It is sown as yeast is sown ; it grows and multiplies as yeast &rows and multiplies, and it always reproduces itself/' Such germs may be scattered by the breath, or through perspiration, or be carried in the garments. It matters little, however, how they are carried (as to their practical, effects), for they are no respecters of persons, provided they find parties or substances which are susceptible to their influ- ences. These germs being seeds, the person attacked by them receives them as a field does the seeds of grain or vege- tables. It matters not whether these seeds are large enough to be seen by the eye, or so fine that they cannot be seen even with a microscope ; they are still seeds, and their progeny often increase and multiply as rapidly as do thistles when sown in a rich soil. I cannot better close the consideration on this point than by quoting from Prof. Tyndall’s " Float- ing Matter of the Air,” pp. 254, 255 : " Thus far, I think, we have made our footing sure. Let us proceed. Chop up a beefsteak and allow it to remain for two or three hours just covered with warm water; you thus extract the juice of the beef in a concentrated form. By properly boiling the liquid and filtering it you can obtain from it a perfectly transparent beef-tea. Expose a number of vessels containing this tea to the moteless air of your chamber; and expose a number of vessels containing pre- cisely the same liquid to the dust-laden ai”. In three days every one of the latter stinks, and, examined with the micro- 232 THE DEVELOPMENT OF LIFE. scope every one of them is found swarming with the bac- teria of putrefaction. After three months, or three years, the beef-tea within the chamber, if properly sterilized in the first instance, will be found as sweet and clear, and as free from bacteria, as it was at the moment when it was first put in. There is absolutely no difference between the air within and that without, save that the one is dustless the other dust-laden. Clinch the experiment thus. Open the door of your chamber and allow the dust to enter it. In three days afterwards you have every vessel within the chamber swarm- ing with bacteria, and in a state of active putrefaction. Here, also, the inference is quite as certain as in the case of the powder sown in your garden. Multiply your proofs by building fifty chambers instead of one, and by employing every imaginable infusion of wild animals and tame ; of flesh, fish, fowl, and viscera; of vegetables of the most various kinds. If in all these cases you find the dust infallibly producing its crop of bacteria, while neither the dustless air nor the nutritive infusion, nor both together, are ever able to produce this crop, your conclusion is simply irresistible that the dust of the air contains the germs of the crop which has appeared in your infusions. I repeat there is no inference of experimental science more certain than this one. In the presence of such facts, to use the words of a paper lately published in the ' Philosophical Transactions,’ 'it would be simply monstrous to affirm that these swarming crops of bacteria are spontaneously generated.’ ” In a former chapter I stated that there is no reliable evi- dence that "spontaneous generation” now exists, and that there is no credible evidence that any life now is produced except from antecedent life. That completes one step. From analogy we may infer that if the doctrine of " spontaneous DUKE OF ARGYLL. 233 generation ” is false now probably it was always so ; and that the laws of nature as regards the production of life have never changed since they were first instituted. Life only from antecedent life is the present law. But this does not inform us whence life originally came. There must have been a beginning of terrestrial life. But the great fountain of life may have had no beginning. There must have been during past eternity a time or point when life could not be derived from antecedent life. It seems that there must have been a first life, —and nothing can be before the first. Nothing now occurs without an antecedent cause. But there must have been a point or time when there could not be an antecedent cause ; and thus we seem to be again forced back upon a self-existing cause, or " cause of causes.” It seems to me that all life had its origin in the great first life. Here we have to deal with original causes, concerning which it is said that we can know nothing. It is true that the human mind cannot comprehend original causes, but it can, in a measure, understand the force of the declaration made to Moses : "I am that I am.” And until some man can show a cause for the origin of life which is more likely to be true, we must look to the great " I Am ” as the fountain from which all terrestrial life came. The Duke of Argyll, quoted before (p. 272, "Reign of Law ”), says : "It is the great mystery of our being that we have powers impelling us to ask such questions on the history of Creation, when we have no powers enabling us to solve them. Ideas and faint suggestions of reply are ever passing across the outer limits of the Mind, as meteors pass across the margin of the atmosphere ; but we endeavor in vain to grasp or understand them. The faculties both of reason 234 THE DEVELOPMENT OE LIFE. and of imagination fall back with a sense of impotence upon some favorite phrase some form of words built up out of the materials of analogy, and out of the experience of a Mind, which, being finite, is not creative. We beat against the bars in vain. The only real rest is in the confession of ignorance, and the confession, too, that all ultimate physical Truth is beyond the reach of Science.” And emphatically there is no place where we intellectually " beat against the bars in vain ” with greater certainty than with the question, " Whence is life?” unless we are willing to refer its origin to the Great First, or Self-existent Life. INCREASING SIZE OF THE BRAIN. 235 CHAPTER X. DEVELOPMENT OF LIFE. The questions already discussed lead to further inquiries concerning inherited traits of character and the increased development of the brain during past ages. Where shall we find a limit to the increasing size of the brain and the consequent enlargement of intellectual capacities ? The brains of vertebrate animals have been increasing in size and activity for many thousand years. The average European human brain of the males is now larger than it was one hundred years ago. Prof. Marsh, in his lecture on "Vertebrate Life in America,” shows that there was a general increase of the size of brains as long ago as the Tertiary period. On p. 48, he writes: "The real progress of mammalian life in America, from the beginning of the Tertiary to the present, is well illustrated by the Brain-growth, in which we have the key to many other changes. " The earliest known Tertiary mammals all had very small brains, and in some forms this organ was proportionally less than in certain Reptiles. There was a gradual increase in the size of the brain during this period, and it is interest- ing to find that this growth was mainly confined to the cerebral hemispheres, or higher portion of the brain. In most groups of mammals, the brain has gradually become more convoluted, and thus increased in quality, as well as 236 THE DEVELOPMENT OF LIFE. quantity. In some, also, the cerebellum and olfactory lobes, the lower parts of the brain, have even diminished in size. In the long struggle for existence during Tertiary time the big brains won, then as now; and the increas- ing power thus gained rendered useless many structures inherited from primitive ancestors, but no longer adapted to new conditions.” If we believe that men have been developed from a lower race of animals during the long past ages, may it not be reasonable to presume that in future ages men may become developed into a still higher race of beings? Why may they not become as much superior to any of the present races of men as these are superior to any of the present species of apes ? This would be carrying development analogies as at present expounded to their legitimate conclusions. However, it would seem evident that a limit to this increasing brain development and expanding intellectual power must be reached some time, and certain facts, taken by themselves, would seem to indicate that this limit is already nearly reached in man. I will briefly state some of these facts : First. The tendency of the highest civilization is to de- crease rather than increase the size of the female brain. The size of the female brain in London, Paris and Berlin is now less than it is among women in localities where society is less highly organized. The brains of males and females among savage or semi-savage races are nearly equal in size ; but in London and Paris the average female brain weighs about five ounces less, or about ten per cent, less, than the average male brain. Of course, the female brain becomes more convoluted and of finer quality in highly INTELLECTUAL QUALITIES. 237 civilized communities than among the uneducated tribes or races. Second. It is seldom that women of very high intel- lectual abilities now marry men of very strong mental cast; and, on the other hand, it is quite uncommon for a man of a very intellectual cast to select a wife with marked intel- lectual power; hence men of extraordinary mental gifts are not to be expected from such unions. A large proportion of the women of the strongest intellectual abilities never choose to marry, and of those who do choose to marry, few have children, or, if they have children, it is seldom more than one or two. The author of " Conflict in Nature and Life ” says, on p. 424 : " This is to be observed in the many unfortunate marriages of literary and other intellectual people. If they secure in connubial relations intellectual equality and com- panionship, there is apt to be no issue, in which case marriage fails of its end. It is a matter of common remark, that the distinctively intellectual marry the unintellectual, and fail completely of companionship, and hence the unhappiness of so many of this class in their marriage relations.” Now, if high intellectual and moral qualities are inherited, and women of genius have no children, or if the men of genius do not marry women of strong intellectual power, how are very high intellectual and moral qualities to be transmitted from parents to children? The intellectual and moral qualities of the mother show quite as plainly as those of the father in the children. Some careful students assert that there are no very marked examples of men of genius who did not have intellectual mothers. By intellectual as applied to mothers who pro- duce men of great intellectual strength, I do not mean O O 7 238 THE DEVELOPMENT OF LIFE. necessarily what are commonly styled educated women, but mothers who have well-developed brains, with strong and vigorous mental make-up, so that if their lives were given to literature or science they would rank among the intellectual women of the age. It is not education that is inherited, but the ability to become educated, or the mental constitu- tion on which to engraft an education. The desire for offspring is a natural one; but, if the in- tellectual organs largely predominate, it is quite natural that the desire for children should be weak, in fact so weak that highly intellectual women naturally strive to avoid the cares, risks and responsibilities of maternity. Besides, the pains and risks of maternity are much less with those who have a good amount of physical exercise in the open air than with those who live in luxury, or have more mental and less physical exercise. Nature here points the way, and those who attempt to go counter to the way she has marked out will not succeed in riding over her decrees. In fact, her decrees in this respect are unalterable, and the anathema of sterility is written against such as flagrantly disobey her mandates. Again, intelligence and the size of the brain bear a striking relation to each other. If the brain in both parents is developed to a great extent, and the offspring inherit this extreme development, births will be correspondingly more difficult. This will prevent the production of children with heads above a certain size; and here again nature has set up a bound that cannot be leaped over. Dr. Dunglison (in " Human Physiology,” vol. 2, p. 447) says : " The records of the Dublin hospital showed that there died during the process of parturition, . . . and probably as a consequence of the injuries to which they were sub- EXCESS OF MALE BIRTHS. 239 jected, 151 male children for every 100 female. There was thus an excess of 50 male deaths amongst every 250 chil- dren, or 20 in every 100, referable, according to Dr. Simpson, to the greater size of the head of the male infant.” Further, he adds, "we may take it for granted that, on a low computation, one in every 50 children dies during labor.” According to further computations, of the 500,000 children born in Great Britain, about " 6,500 of the offspring die during labor, and one-fifth of that number are lost in consequence of the sex and size of the male child.” "In Great Britain, therefore, the lives of 1,300 infants are lost annually in childbirth from the operation of this agency.” Not only the risk of the child’s dying during labor will be increased as the size of its head becomes greater, but the risk to the mother in labor will be augmented by the increase of the size of the head. After stating that the number of male births in Europe is about 106 to 100 female births, Darwin says (p. 243, "Descent of Man”); "Prof. Faye remarks that 'a still greater preponderance of males would be met with if death struck both sexes in equal proportion in the womb, and during birth. But the fact is, that for every 100 still-born females, we have, in several countries, from 134.6 to 144.9 still-born males. During the first four or five years of life, also, more male children die than females; for example, in England, during the first year, 126 boys die for every 100 girls, a proportion which in France is still more un- favorable.’ ... We have before seen that the male sex is more variable in structure than the female ; and vari- ations in important organs would generally be injurious. But the size of the body, and especially of the head, being 240 THE DEVELOPMENT OF LIFE. greater in male than female infants is another cause; for the males are thus more liable to be injured during parturition. Consequently the still-born males are more numerous.” But there is still another serious bar to the upward intel- lectual progress of men. Statistics show that with largely increased size and activity of the brain come certain mental diseases. Melancholia, insanity and a disposition to suicide are alarmingly on the increase among the highest-cultivated races. These almost universal accompaniments of the highest civilization tend to thin out those who might other- wise become the most intellectual. But, in regard to the necessity for large brains through which to manifest great mental power, the objection is made that some men with small heads accomplish more than others with large heads; so what is the necessity of laying so much stress upon the size of the brains ? Some men with small bodies have more muscular strength than other men with large and apparently well-developed bodies. But does this indicate any general advantage of small bodies when muscular power is needed? As a general rule (as all know) a well-built man weighing two hundred pounds has more muscular power than another of similar proportions who weighs one hundred and fifty pounds. The same general rule applies to mental power, in connection with the size of a man’s brain. Some brains are of finer texture, better dis- tributed, more convoluted, and consequently more active; but general rules concerning size and quality apply to both brain and muscle. We find the assertion that certain great men have had small heads, and from this fact an attempt has been made to discredit the theory that size represents the measure of power in the intellectual faculties; but I have yet to learn SIZE OF THE BRAIN. 241 (as a general rule) anything which shows that size is not very important in the brain, if we wish for intellectual power. If the size of the brain is of little importance, why is it that those whose brains weigh less than thirty-five ounces are almost invariably idiots? The most conspicuous exception to the general rule con- cerning large brains is exemplified in J. F. L. Haussman, a German mineralogist, whose brain was under the average weight, it being only forty-three and one-quarter ounces, or over five ounces less than average weight of the brains of his countrymen. But Haussman died at the age of seventy- seven, or at an age when the brain weighs nearly ten per cent, less than in early life. At the age of thirty-five probably his brain was nearly the average weight. I have not seen a likeness of Haussman, but I believe such would show that his head was long and narrow, and with a large part of it in front. The nearest case to this that I have known is that of J. G. J. Hermann, the Ger- man philologist, whose brain weighed forty-six and one-half ounces, or two and one-half ounces less than the average weight; and yet he became quite learned, and very popular with German students. Soon after Gambetta’s death many newspapers published the statement that his brain weighed only forty-six ounces, or three ounces less than the average weight of the brain among educated Frenchmen. Per contra, the statement was published later that Dr. Laborde, who examined Gam- betta’s brain, reported to the "Faculty of Medicine” that "the brain was of exceptional size,” and highly convoluted in "the regions assigned as the centre of the power of language.” This latter statement seems much more likely to be true than the former. However, a brain of average 242 THE DEVELOPMENT OF LIFE. size, having a large proportion of it in the frontal region, will give much more intellectual acumen and force than a brain considerably larger if a large proportion of it is in the regions representing the animal passions. We do not look for any strong intellectual force if the brain is not well developed in the frontal regions. Not only the quality of the brain but its proper shape has much to do with the manifestations of mental power. These, properly correlated with size, will give a general measure of brain power. Bain supposes that all our intelligence, including memory, is located in the gray substance which envelops and enters in among the convolutions of the brain. This gray matter averages about one-tenth of an inch in thickness in the aver- age healthy human brain. But supposing that in excep- tional cases this gray matter should be double the average thickness, and be of good quality, should we not naturally expect extraordinary manifestations of mental power, accord- ing to the size of the brain ? The writer has frequently heard it stated that the heads of Lord Byron and Napoleon were small; but Huxley states that the brain of Byron weighed 1807 grammes, or over sixty- three and a half ounces, or over fourteen ounces more than the average brain of Englishmen. Napoleon’s biographer states that the head of Napoleon was one of the largest and best formed he ever saw. The brain of Napoleon weighed slightly less than Byron’s, or a little over sixty-two ounces. According to Prof, Calderwood’s published tables, the brains of Daniel Webster and Louis Agassiz each weighed only about fifty-three and a half ounces, or four and a half ounces above the average brains among the most cultivated LARGE BRAINS. 243 races. But Dr. W. A. Hammond says that "Webster’s brain (allowance being made for disease which existed) weighed sixty-three and three-fourths ouncesand further, that his " cranium was the largest on record, being one hun- dred and twenty-two inches.” And the writer has seen it stated elsewhere that the brain of Webster weighed over sixty-two ounces; and he believes the larger figures are correct. Prof. O. S. Fowler, who measured Webster’s head, writes, "The author found Webster’s massive head to measure over twenty-four and a half inches.” Fowler also states that his forehead was uncommonly high. Quatrefages states that it has been reported that the brain of Oliver Cromwell weighed over seventy-eight ounces ; but, he adds, " There is not the certainty we should wish for about these figures.” But it should be borne in mind that the weight of the brain does not always bear the same ratio to the skull capacity; that is, the specific gravity of the brain in certain persons is greater than in others. Fowler states that the head of Napoleon Bonaparte measured over twenty-four inches in circumference. Dr. Gall states that " Moderns have (in their pictures) left Napoleon’s head in its natural size, but placed it on a body of colossal proportions, to make it conform to their ideas of proportion.” Ben. Franklin’s head measured considerably over twenty- four inches in circumference. Cuvier’s brain weighed over sixty-four and a half ounces, and, going through the whole line of illustrious men, we find, as a general rule (with very few exceptions) that large brains, if well proportioned, indicate great mental force ; but a man with a brain of only average size, if it is uncommonly active, may exhibit con- 244 THE DEVELOPMENT OF LIFE. siderable acumen. But I doubt if a profound and compre- hensive thought ever originated in a brain of much less than average size. No doubt that thorough investigation would put to rest all assertions that great power can be found in small brains, unless in very exceptional cases, and these will be as exceptional as instances of small men or small animals possessing surprising strength and activity. To illustrate, we may find a pugilist weighing one hundred and twenty pounds who may beat an ordinary man weigh- ing two hundred pounds, and this on account of his superior training and activity. The same rules may be applied to mental manifestations, or brain power. Here, then, is an important point regarding the brain structure. But if the brain and nervous system are de- veloped out of due proportion to the muscular system, so that the rest of the body is incapable of furnishing proper sustenance to the brain, then disastrous results are sure to follow ; and here is another limit which cannot be passed. But, says one, the law of Evolution, through which the less useful disappears, and the most useful is preserved, will so adjust the mutually dependent conditions of mind and body that a general improvement in both physical and mental capacity may be confidently looked for. But nature has apparently set certain bounds to this de- velopment, through the well-known fact that generally the less developed races increase faster than the highly developed races. In many civilized communities the higher classes are running out, and they would, before long, become extinct if it was not for the admixture of their blood with that of descendants of lower classes. Says a very vigorous writer : "In France there is greater prolificacy among the inhabi- tants of the poorer than among those of the richer depart- INCREASE OF BIRTHS AMONG LOWER RANKS. 245 ments. The aristocracies are everywhere running out, as in the Roman empire, and they would become extinct but for constant accessions from the ranks below; and some come up from almost the very bottom. Reigning dynasties are not apt to last long, and once a family has reached the pinnacle of human greatness its doom is written.” As an example of this, take the Bourbon family, which one hundred years ago controlled about half the thrones in Europe. Where now are its prominent descendants ? Look at the increase of the former slave population in the United States. Where and when has a highly educated and highly developed race increased and multiplied as rapidly as they did ? Who now rear the largest families ? the laboring men, farmers, and mechanics, or those who live in habits of laborious study? In order to facilitate the production of a superior class of children and the rearing of prosperous families there must be a somewhat befitting sympathy between the parents. This sympathy is much oftener wanting among the highly educated classes. Delauney says ("Popular Science Monthly,” Decem- ber, 1881) : "The biological considerations we have adduced explain to us why the two sexes tend to diverge from each other as we proceed from the lower to the higher classes. Both sexes among peasants and working-people having nearly the same moral and intellectual faculties, they can sympathize with each other, and have no reason for becoming estranged. It is different among the intelligent classes, where the two sexes, in consequence of the increasing pre- eminence of man, not having the same ideas, the same senti- ments, nor the same tastes, cannot understand each other, and form separate coteries. Moralists have long taken notice of the separation, which is of force in the family and 246 THE DEVELOPMENT OF LIFE. in the meetings of men and of women, which seem to be increasing from year to year.” It will be said that this divergence should not be allowed to exist. Very true; but human beings will consult their own tastes. If we assert that such divergences are evidence of depravity, that does not change natural laws. Nature will not lessen her demands at the requests of phi- losophers or military chieftains. Her demands must be paid to the uttermost farthing. Without care the whole tendency of animal and vegetable nature is to revert to the original type. It is only through struggles that beneficent develop- ment takes place. Without this continual struggle the descendants of present highly developed races of men would go back towards the original type much faster than they came up from that condition. By original condition I do not mean that they came from a radically different race, but that without this struggle the tendency is to revert to the primeval condition of man. We are told that the general course of Evolution is for- ward, and that every succeeding generation is becoming, on the whole, better and more wisely developed. But it is a question whether we have at present any living men who are superior in mind or in real philosophic strength to Thales, who flourished six hundred years before Christ, or Socrates, four hundred years before Christ, or Plato his disciple, or Democritus, or Zeno the Stoic, or Aristotle. I fail to per- ceive one Avhit of gain in two thousand years in the vigor of thought, clearness of expression, or acuteness in meta- physical reasoning. And if the present generation had been placed here, with no printed books, and no greater facilities for education than were common two thousand years I do not believe the living world would show itself superior to, 247 ANCIENT GREEKS «. ENGLISHMEN. if it would equal in intellectual strength, that of two thou- sand years ago. Let this expectation of any surprising intel- lectual development from the present tendency of thought be given up. A vigorous and apparently well-informed writer contends that the ancient Greeks as a race were supe- rior in intellectual ability to the present race of Englishmen ; and much may be said which seems to accord with his state- ment. Another fact is well worth considering. We have no reliable secular histories which date back over four thousand years. The oldest written language, notwithstand- ing extravagant claims to a very high antiquity of some Ori- ental languages, probably does not date back five thousand years. How did it happen that the ancient Greeks, within about two thousand years after the invention of the first written language, became developed to such a height of intel- lectual vigor that there should be no perceptible gain in intellectual acumen or strength during the next two thousand years, if men had been aeons in becoming developed from animals to real men ? Is it not strange that there should be such a sudden stop in the growth of intellectual acumen so soon after the race of men got so fairly away from brute life as to become capable of leaving historical records ? It may be asserted that, with proper educational privileges, two thousand years is long enough to develop a race from a very low to a very high state of intelligence. Granted ; but then let us go back more than a thousand years prior to the Grecian development, or to within a thousand years of any generally acknowledged date of the first written language, or to the time when it is generally believed that Moses, the Hebrew law-giver lived. Can any one justly assert that any man has lived during this century who has shown a greater intellect than the laws and precepts attributed to Moses 248 THE DEVELOPMENT OF LIFE. would indicate that he possessed ? His civil code is the basis of much of our present law, and in many respects it has not been improved upon. If it is asserted that this was in consequence of Divine inspiration, I shall not deny that; but, inspiration or no inspi- ration , God has never used weak intellects to lay foundations of laws and customs destined to last thousands of years among the most learned and enlightened nations. Even if the Pentateuch was written from traditions by some one who lived in later ages, as some suppose, that does not lessen the great prominence of Moses as an actual law-giver. Moses exhibited intense intellectual vigor, and no higher has been seen during the past thirty-four hundred years. We are not warranted in expecting that men will soon make a decided gain in their general intellectual strength. O O O But, to make a wider application of this principle, we see that the course of development or degradation of races of men is quite similar to that of the rise and fall of families. But the time required for the rise and fall of a race is much longer than that for the rise and fall of a single family. The family may be taken as a type of a race. All must see that a certain amount of development or degradation exists in many directions. This accords with the general principles of Evolution, and apparently applies not only to men but to the whole animal creation. But whatever one’s opinion concerning the past development of the human race may be, and if we believe that the race has nearly reached its limit of physical and intellectual de- velopment, may we not at least fondly hope that in moral ideas and moral character men will yet reach a much higher plane than has ever been reached by any class of men ? If the course of nature generally tends towards higher ends, HOPE 249 why, at least, should not the moral sense and moral faculties be allowed to reach a much higher standard than has hereto- fore been reached by any people? Who knows but the hopes of a blissful immortal life, which were long ago cherished by heathen philosophers like Socrates and Cicero, and in later ages by millions of Christians, may be the silent outspeakings of this possibly universal law of nature ? Hope has always claimed that " there’s a good time com- ing.” Who can properly estimate the moral possibilities which lie as yet undeveloped in the womb of the future ? There is certainly abundant need of and opportunity for a great im- provement in this direction. PABT 11. ETHICAL SPECULATIONS AND INQUIRIES. ETHICAL SPECULATIONS AND INQUIRIES. CHAPTER XI. TO WHAT EXTENT WILL ONE’S BELIEF MODIFY HIS MORAL CHARACTER ? Some assert that the influence of belief, especially religious belief, is merely nominal. A distinction should be drawn between what a man believes and what he professes to believe. It is not profession, or what a man professes, that has lasting power, but the belief which is ingrained in the character will have a powerful effect upon his whole life. If a man believes that by investing in certain property he will become rich, does any one suppose that such belief will not influence his acts? In religious matters, if a man hardly knows whether he believes or not, but simply falls in with the current, as many do, and professes to believe with the majority, because it is easier to go with than against the current, such belief is of little value, and will be likely to change as soon as his surroundings change. But if a man has a firm conviction that a certain course is right, and also determines to be himself right, then his belief avails much towards giving character to his whole life. 254 ETHICAL SPECULATIONS AND INQUIRIES. It has been said that Washington believed that "honesty is the best policy ; ” and doubtless he was correct. But if a man’s honesty does not spring from a higher motive than common policy, it will not be of a very high type. The same rules apply to a man’s belief in a future life and its rewards or retributions. If he really believes that he will consciously exist in a future world, and that what he does here will have an important effect on his future happiness, most certainly this belief will exert a powerful influence in shaping his acts. But if he has simply a half-conscious idea that he may possibly exist, or perhaps not exist, then such a belief cannot have any marked influence on his character. Hugh Miller says : " That belief in the existence after death, which forms the distinguishing instinct of humanity, is too essential a part of man’s moral constitution not to be missed when away; and so, when once fairly eradicated, the life and conduct rarely fail to betray its absence.” The belief of a nation will influence the character of its laws and habits, for nations are made up of individuals. If the individuals of a free nation believe in honesty and integrity the rulers will feel this influence, and we may expect an equitable enforcement of just laws. The decline of religious belief is now making itself very apparent in European countries, controlling, in some respects, their politics. Formerly, in Italy, the words of the pope and the priesthood, in many respects, had the force of law. But times have wonderfully changed. Many who once bowed submissively now care little what the pope and priests may say. Those who have relapsed from belief into non-belief are very different from what they formerly were, and new motives must be supplied in order to influence their BELIEF IN IMMORTALITY. 255 acts. Some, who formerly believed in the immortality of the soul, now believe that the death of the body is the last of them. If you wish to keep such in a right course it will not do to appeal to the motives which formerly influenced them. It ever has been very dangerous to the welfare of the state for lawless classes not to feel some sense of moral responsibility ; for you can never tell to what excesses such may go while unrestrained by religious or moral belief. This is more especially true when the immoral become atheistic. But I would not advise preaching untruth to control even the immoral, for untruth is not to be defended. "Truth is mighty and must prevail,” and no lasting good can come from teaching error. But it is not teaching error to pro- claim to its fullest extent the doctrine of moral responsi- bility. I am well aware that many have tried to show that there is no unvarying moral standard, and have further attempted to show that all our ideas of right and wrong are connected with remembrances of pleasures or pains; or are the inherited echoes of pleasures or pains experienced by our ancestors in connection with various courses of conduct. Keferring to this idea, Mansel says (p. 143, "Metaphysics ”) : " Pleasure and pain, so far as they are objects of desire and aversion, do not probably lie in the things by which they are caused, but in the actions by which those things are brought into contact with the person affected. But the actions, and, in some degree also, the feelings which prompt them, may be exhibited in another point of view not merely as pleasant or painful, but as right or wrong. The exist- ence of these terms, or their equivalents, in every language,, indicates a corresponding phenomenon in the universal con- sciousness of mankind which no effort of ingenuity can 256 ETHICAL SPECULATIONS AND INQUIRIES. explain away. Indeed, the very ingenuity of the various attempts that have been made to identify the conception of right with that of expedient, or agreeable, or any other quality, is itself a witness against them ; for no such elabo- rate reasoning would be required were it not necessary to silence or pervert the instinctive testimony of a too stubborn consciousness.” Even if the present popular assumption that our moral intuitions and tendencies are inherited, or have descended to us as the unconscious effects of pains or pleasures expei’i- enced by our ancestors, is correct; or if they are inherited as directly as the peculiar qualities of a pointer dog are, that fact in no wise changes another fact, viz., that a certain course of conduct will (all things considered) be the very best course a man can take. That best course is the only perfect one, and is imperatively demanded by a perfect moral standard. Even if our moral sentiments and feelings have been changed or modified in the progress of Evolution through many generations, that fact does not obliterate or change the other probable fact, that the Deity, or some being or power which established the very laws of nature, has predestined this very course from the very beginning, and thus this very course of development may be in accordance with an original design. The course of development which has resulted in our present moral intuitions or sentiments may have come through natural laws ; but full compliance with these laws may constitute conformity with a perfect moral standard. Perhaps a better appreciation or more correct apprehen- sion of moral laws may yet become developed as education and general intelligence increase. MORAL RESPONSIBILITY. 257 Loss of belief in moral responsibility, with the unprin- cipled, leaves the impression that they may do as they please, no matter how inhuman or wrong the objects they wish to accomplish, provided they have physical force sufficient to accomplish their purposes. We see this prin- ciple of action cropping out in Ireland, Germany, France, Italy, and, in fact, to some extent in almost every civilized country. It was reported (“ Contemporary Review,” 1882) that in a debate in the Italian Parliament on matters pertaining to the welfare of the poorer classes in Italy, Signor Gio- vagnoli said: "In times past religious belief helped to mitigate the sufferings of the poorer classes. But now that science has done away with religious delusions even the poor aspire in this world to their share of happiness, of bread, of meat, and of wine ; and unless science can also do away with the delusion of these necessities, social violence will make short work of legislation and legislators.” The atheistic scout the idea that their teachings tend to encourage social violence. But what docs the history of the past show? The prophecy of Signor Giovagnoli, "that social violence will make short work of legislation and legislators,” will probably come true, provided unprin- cipled masses ever become strong enough to overpower proper authority, if science dispels all of what he calls "religious delusions;” for, under such circumstances, the partially dependent classes will not submit, as they formerly submitted, and will, as far as possible, take matters into their own hands, regardless of right or wrong. Ignorant men cannot be governed by philosophical appeals, for they do not comprehend such appeals ; but history abundantly proves that they can comprehend the commands of unprin- 258 ETHICAL SPECULATIONS AND INQUIRIES. cipled adventurers who promise bread or blood, and greater influence, both social and political. This view concerning the actions of masses maddened by wrongs, either real or supposed, and their well-known brutality under such circumstances, well accounts for the blasphemous and atheistical utterances of the most fanatical of the Communistic leaders. They well know that the first step towards getting the ignorant and vicious populace into condition to be impelled to deeds of violence and outrage is to destroy in their minds all idea of moral responsibility. No prominent people or nation having clear ideas of moral responsibilities ever existed which did not also have some sense of religious responsibility. Thus the statement of the signor, above quoted, properly translated, means this ; that, all hopes of immortality being given up, the unprincipled and vicious classes will have nothing but present fear to restrain them ; and if they should lose their lives while in open violation of law or right, it would be of no great consequence, for that would be the end of them, and hence they could be as outrageous as they de- sire, without any lasting harm to themselves. Let the idea get firmly implanted in the minds of the majority of a people that there is no conscious hereafter, and before long the probable result will be violence and brutality such as the world has never witnessed except in the worst states of barbarism. I am aware that the assertion has been made that there are some four hundred millions of Buddhists who are practi- cally atheists, and do not believe in immortality, and that they live peaceably and cultivate the moral virtues. But such an assertion concerning their atheism and disbelief in immortality needs to be received with many reservations. BUDDHISM. 259 First, the Buddhists might be properly called agnos- tics, rather than atheists ; for they do not deny that there was a first cause, but simply leave inquiries into this out of view. They inculcate practical duties rather than inquiries into what is beyond the comprehension of mortals. It is true that, in a certain sense, they do not believe in immortality, but they do believe in a future life, and their belief in ten billions of years of happiness in one of their heavens, or ten millions of years of misery in one of their hells, ought to be a pretty good substitute for a belief in immortality, or at least a sufficient inducement to avoid their hells by a virtuous life, and to gain their heaven by proper devotion to the tenets of Buddhism. Their Nirvana, instead of meaning annihilation, as that word is commonly understood, is very different from that, and is rather an absorption into the infinite than absolute non-existence. But they expect to be dead to all earthly pleasures and pains ; and this, in principle, is not very differ- ent from that perfectly inactive state of rest which some Christian teachers in former times talked about, viz., a Sabbath of inactivity rather than one of activity. For practical purposes, Buddhism enjoins the performance of moral duties and living a virtuous life, and also urges their necessity in a manner quite similar to that employed by the apostle Paul; and thus the assertion that the belief of Buddhists is nearly equivalent to modern atheism is very far from being true. We can imagine in a faint way what the result of genuine national atheism would probably be, from what was done during the French revolution, though only a fraction of the violent agitators there were entirely free from traces of this so-called "religious delusion.” Had it not been for the little o 260 ETHICAL SPECULATIONS AND INQUIRIES. of this restraining influence left, probably three murders would have been committed where there was one, and the horrors of such a situation can be better imagined than O described. Though I use the term "religious delusion," let it not be understood that I believe pure religion has not a real existence. Religious sentiments are, in some sense, a part of man’s very nature. lam aware that revolting crimes have been committed under the plea of defence of pure religion. It is too true that fanaticism and bigotry, both religious and political, have been the parents of grievous evils. One might well exclaim, " O Religion! ” as well as " O Liberty ! what crimes have been committed in thy name ! ’’ When scientific men deal with mathematical or other problems which can be demonstrated, we may generally put confidence in their conclusions; for, if they make mistakes in their reasoning, such mistakes may be pointed out. But the moment scientists enter the regions of speculation their conclusions are no more reliable than the conclusions of speculative theologians. Both are right so long as they confine their statements to known facts ; but both may be entirely in error in their speculative conclusions. We are answered that the honest scientist is seeking for truth alone and he has no reason to deceive the people. What reason has the honest theologian to deceive people ? There are scientific delusions as really as there are religious delusions ; and when they enter the regions of speculation both parties are equally likely to arrive at false conclusions. Let us disabuse ourselves of the idea that delusive ideas pertain exclusively to religious beliefs. The history of so- called scientific speculations shows that the fallacies of scien- tific hypotheses have been very extensive. POLITICAL EFFECTS. 261 But to return to the consideration of the political effects of a disbelief in religious and moral obligations. We are O c? aware of the ready answer, that eminent atheists do not show a blood-thirsty disposition. Granted; but men of their social and intellectual position are above the pinchings of want, and they are educated to a degree which enables them to see the untold evils that must result from a com- munistic outbreak, accompanied, as it would be, by outrages upon those called the upper classes; for they themselves belong to the upper classes, and their own personal interests are involved as directly as those of any other class, and hence we see them on the side of law and order. But, in case of a communistic rising, they could not control the result of their own teachings; and if in such a case they attempted to control the violent, they would fall before blind fury as soon as other persons. We are told that under a free government there is no danger of such outbreaks. Let us not deceive ourselves. We are also reminded of the benefits of intelligent instruc- tion and the great blessings that flow from general education ; and to that I say amen, provided the education is of the proper kind; but I have no sympathy with those who wish to let the moral education of children take care of itself. Much has been written about letting the generous natures of children be developed; but if they are brought up without moral restraint, how will their natures be developed ? If all the wishes of children are gratified, what kind of men shall we have ? In the majority of cases we shall have poor specimens of humanity. The passions of all need moral restraint, and unless children receive some kind of 262 ETHICAL SPECULATIONS AND INQUIRIES. moral as well as intellectual teaching they seldom become valuable citizens. One very singular fact connected with all philosophical inquiry into mental and moral acts is the mutual dependence of several apparently diverse beliefs. For instance, nearly all philosophers who believe in the existence of an Omnipotent Creator also believe in a future conscious existence. Nearly all who believe in a Creator believe also in the ex- istence of an absolutely unvarying moral standard, and that moral laws are as permanent and certain in their operations as the general laws of nature. Doubtless, if we could per- fectly comprehend all truth, we could understand what this standard requires, and all would be obliged to agree not only to the existence of this standard, but also to what men should do to conform to its requirements. It must not be understood, however, that a perfect moral standard would require that all persons should act alike in all cases ; for of necessity there must be different positions and circumstances in life. For instance, it might be in conform- ity with a perfect moral standard for one who is famishing with hunger to take and eat food, which under ordinary circumstances, would belong to another. Again, those who believe in an absolute moral standard generally believe in the immortality of the human soul. At first sight there would not seem to be any necessary or logi- cal connection between morality, God and immortality. But why should those who generally reject belief in the existence of an eternal moral standard and an eternal Law-giver at the same time disbelieve in the soul’s immortality ? Many atheists believe in morality and in the performance of moral duties; but as their standard of morality can admit of no obligations to any higher power than humanity WHAT IS MORALITY ? 263 itself, it cannot be an unvarying standard, for humanity is constantly changing. But what is morality ? What constitutes an act a moral one ? The lexicons tell us that " morality is the relation of conformity to the true moral standard, or rule.” But what is this standard which is called the true ? On what basis does it rest, and in what does it consist ? What is the real foun- dation on which the moral quality of an act must stand, and what is the abstract quality which expresses the difference between a moral act and an immoral one? There must be something in the very nature of things which underlies the principles upon which morality apparently rests. What is that foundation ? I am aware that many think it is not scientific to sup- pose the will of the Deity can have anything to do with the absolute moral quality of an act, and that the real quality is the same whether the act is in accordance with the will of the Deity or not. Such a position is satisfactory to such as do not believe the Deity ever made a revelation of His will to man. These assert that inasmuch as what seems moral to one may seem immoral to another, therefore there cannot be an absolute code of morals which is applicable to all men. Some trace all evil to selfishness, and others all good to un- selfishness. Still others assert that the moral quality of an act is entirely dependent upon its utility. Now I suppose that any act, which, taken in all its bear- ings, tends to the best good of mankind and their ultimate happiness, cannot be otherwise than moral; and it is also, in one sense, an act of highest utility. And, further, I cannot believe that the performance of any act which is strictly moral can be of ultimate injury to the doer, when we take into consideration all its bearing. An objection 264 ETHICAL SPECULATIONS AND INQUIRIES. may be noted in the case of a person who sacrifices his present interests, or his life, for the good of others. In case of one whose life is voluntarily sacrificed to save others the question may be raised how that can result in good to the one sacrificed? That raises another question which leads into realms that lie beyond the reach of human experiences, and hence, from want of any certain knowledge on this point, we must leave the question unanswered, or else refer its answer to a power or being wiser than we are. I cannot believe, however, that the principle of self-sacrifice has been placed in mankind except for wise reasons. But it seems natural to suppose that a perfect moral standard must be in harmony with the physical laws of the universe, or with what are called the laws of nature, for both are believed to be established by the same power. Following out this idea, we may suppose that, as a general rule, men who live up to the highest moral standard which commends itself to the judgment and reason of intelligent and enlightened men enjoy better health and live longer than those who are careless in regard to these things. Also, that the man who attempts to live up to the standard of morals set up by Jesus Christ will enjoy better health, and that (other things being equal) in consequence of this better health he may expect a longer life and much greater happiness than one who disregards this high standard of morals. The very fact that such physical and mental results follow high moral action seems to indicate, even if we assume that utility, or conformity with the laws of nature, forms the true basis of morals, that the maxims of Jesus, judged by either standard, are of the highest order of utility. And this fact, again, would seem to indicate that the origin of these maxims 265 TEACHINGS OE CHRIST. may be found in the very highest wisdom. Can we then wonder that so many believe that these maxims and precepts were dictated by wisdom from above ? Of course, believers in the teachings of Christ and his apostles will readily acknowledge that some necessary logical connection must exist between belief and non-belief in God and belief or disbelief in the existence of the human soul. In regard to the question whether there is an unalterable moral standard, it seems evident that there can be no definite answer unless we first decide in our minds whether there is an Infallible Law-giver; or, in other words, we should first decide whether there is prepondering evidence of the existence of an Infinitely Wise Being or Power which established the laws that govern the universe. If such a Being exists, He may prescribe a standard which will be in complete harmony with universal laws. But if there is not clear evidence of the existence of such an Infinitely Wise Being or Power, then an unalterable moral standard may not be supposed to exist; for with changing circumstances or surroundings the quality of moral actions will be likely to change. Kant held that neither the existence of God, nor the immortality of the human soul, nor the freedom of the will could be demonstrated through any scientific arguments or speculations; and yet he believed in God, and in moral and religious obligations, though rejecting much which is taught as theology. He also believed in an unvarying moral standard, and in the freedom of the will, without which freedom these moral laws could not be obeyed ; and, further, that without the existence of" God and the soul’s immor- tality there would be no final cause or motive for human conduct.” "He further believed that men may be placed 266 ETHICAL SPECULATIONS AND INQUIRIES. in a state of felicity agreeable to morality, provided by and to be obtained through God, in another and a better life.” —("Penny Cyclopaedia.”) Kant’s opinion, though not capable of demonstration, cannot be refuted, and if the teachings of science are set up against a moral standard, one assertion will balance the other. Science is not genuine if it has no demonstrable basis ; and thus I believe that what is falsely called science may be at fault rather than belief in an infallible moral standard. Science should be definite, clear, and not delu- sive, and that which claims to be scientific, if it leads away from a proper moral standard, —if an unchangeable moral standard is not a myth, must be falsely called science. Much, however, is taught for science which cannot be disproved, but which, whether so intended or not, does tend to undermine ideas of any direct responsibility to a Supreme Intelligence. Doubtless some, who dislike to lessen conscientious regard for moral obligations, do teach what in most minds must raise questions which will of necessity cause them to doubt the existence of real moral obligations. Take for instance the question of the descent of man from the lower animals (provided it is shown that he has so descended), and this, with many, will have (though not justly) a direct bearing upon the question whether there can be any absolute standard of moral responsibility; for they will ask, if there is such a responsibility, where is the line between the brute and the human which marks the bounds of moral responsibility? This would seem like trying to draw a line between daylight and darkness. Where in the twilight does this line come? If the stronger and fiercer animal commits no wrong when it mutilates or drives away DOES MIGHT MAKE RIGHT ? 267 its weaker or less courageous relative, how can it be said that man does wrong when he commits a similar act, if he has descended from a like animal ? Does not this look like the doctrine that " Might makes right ? ” If the higher animals which appear to have in kind the general mental qualities that men possess commit acts of violence without incurring moral guilt, why should men, who are simply higher developed animals, be held morally responsible for like acts ? Human governments hold madmen and fools irresponsible, where men of intelligent and sane minds are held guilty, if they commit acts of violence. But on what law can this distinction be founded, if there is no absolute standard ? Every intelligent man at some time during his early child- hood has been considered irresponsible, but with the increase of intelligence there came a time when he became responsi- ble. Doubtless some reach a state of partial moral responsi- bility long before it is reached in all respects ; and perhaps some never reach that state in all respects. Probably in no two children will this moral responsibility be reached exactly alike, or at exactly the same age. A similar state may possibly have been reached between the brute and the human at some time during past ages, provided men have been developed from the brutes. But we ask at what stage of the evolution of man from the brute does moral responsibility commence? To whom does this responsibility or moral obligation run? Does it run to men, or to a higher power? How can it run to a higher power when we deny that there is a Supreme Law- giver? This is a practical question, for we want to know where moral responsibility commences and where the con- sciousness of right or wrong commences. Is conscience an O O 268 ETHICAL SPECULATIONS AND INQUIRIES. inborn faculty, or is it entirely the result of education ? Is it in the very composition of our natures ? Again, if conscience is inborn, is it a safe guide? Surely, if it is badly educated, all must know that it is not a safe guide. Then what is its value? Its natural voice would seem to he, "Be right, do rightly, act rightly; ” and even though it is not an infallible guide, men ought to be thank- ful for its warnings, for on just such warnings the safety and welfare of society largely depend. It seems to me that in man the sense of right and wrong is inborn ; but the standard according to which this inborn faculty acts is greatly modified or changed by circumstances of birth, education, and other surroundings. But these surroundings, while they modify the standard, which men in different localities accept, in no wise change the actual and absolute moral standard, any more than men of different ideas of geology can change the geological strata. The strata are there, and no man or set of men can place the granite above the limestone formations. The same Almighty Power which placed the granite on its everlasting foundations and in its present position has also (I believe) set up an equally solid and stable moral standard. But a difficulty occurs when men who are warped by their own desires and interests attempt to interpret or explain that standard; for the standard they accept and act upon is apt to be somewhere nearly on a plane with their desires. Hence the word im- perfect, both in their standards and their acts, may be justly written against the lives of all men who make or set up their own notions for a moral standard. And hence the necessity of some standard to which all can appeal as the one unerring moral standard. I think no one will dispute the desirability of such a DATA OF ETHICS. 269 standard, provided we could tell its exact limits and bounds. We have the " data of ethics ” from able writers ; but the very ablest of moral philosophers who argue from the light of science or of reason differ greatly among themselves in regard to the real force and position of these data. It seems evident that no perfect moral standard can be of human origin, for the moment we leave the demonstrable for the unknown, theories which look perfect to one seem very im- perfect to another, and thus endless discussions result. We need to deny the assumptions of a considerable part of what is supposed to be scientific concerning fundamental moral principles, because many of these rest upon questionable hypotheses rather than demonstrations. If, as claimed by Herbert Spencer and others, our moral ideas are based simply upon inherited instinct or impressions handed down through the experience of many generations, it does not seem probable that there can be any demonstrable moral standard ; for the strength of these inherited impres- sions will increase or decrease with the state of civilization and other surroundings. But, if moral impressions and ideas come entirely through inherited instinct, how does it happen that some men of very limited opportunities for education, and whose parents have not shown any extraordi- nary strength of moral development, have been so greatly ahead of all their contemporaries in the strength, depth, and clearness of their moral apprehensions? Take the case of Jesus Christ, for instance, and look at it from the Spencerian stand-point. Here we see a man having only limited opportunities for education, surrounded by and brought up among a people held under bondage by the Romans, burst forth as a moral light high above all other men who preceded or succeeded him. Leaving out 270 ETHICAL SPECULATIONS AND INQUIRIES. of view everything concerning his supposed miraculous birth and his Divine nature, and not affirming or denying anything concerning the nature of the miracles which the evangelists state that he performed, or whether he rose from the dead, as believed by Christians, we will now look at him merely as a man, as this evolutionary theory necessi- tates. I ask, how did it happen that Jesus Christ inherited such a wonderful depth and clearness of moral sense that he stands in this respect high above every other moral teacher who has ever lived ? Some have attempted to show that his moral precepts were not of much higher order than those of other teachers ; but until the works of such teachers are produced such assertions lack a proper foundation. Passages have been quoted from Confucius, Buddha, Zoroaster, Plato, and Socrates containing excellent moral precepts. Perhaps those quoting these precepts think they have made out a probable case; but, in so far as the writer is informed, all such quoted passages have failed to reach anywhere near the sublime moral heights of the teachings of Jesus. Such authors and quotations have to meet statements of candid infidels, who, having no belief in Christianity, yet have freely confessed that the moral teachings of Jesus are high above all the teachings of other men. Besides, some four hundred millions of the human race are nominal Christians, and the nations called Christian comprise the most highly educated and cultivated races on the globe. This fact indicates that great numbers of intelligent men believe that the utterances of Jesus are in a moral sense the highest ever proclaimed by man. This is a kind of testi- mony that no denials can shake. I am aware that the three hundred and seventy millions of 271 BUDDHISTS v. CHRISTIANS. Buddhists may (as far as numbers go) be set over against the number of Christians, and that both Jesus and Buddha taught that total unselfishness is a high moral quality ; yet when we compare the results and the reasonableness of their lives and their teachings, we see that they are not at all comparable. Buddhists teach that Buddha, during one of his many lives, at one time saw a tigress and her cubs fam- ishing with hunger, and he carried his benevolence so far as to give his body to satisfy their hunger; which certainly was benevolence run mad. We find no such unmeaning benevo- lence in the teachings of Jesus. Again, in and beyond his moral teachings, Jesus asserted the existence of a kind, compassionate, and forgiving Heav- enly Father. But such a Deity has no existence in any other religion. Forgiveness is the peculiar attribute of the Deity whom
