Read before the American Social Science Association, at the Lowell Institute, Boston, March Ist, 1870. —By Prof. Francis Bacon, M. D., of Yale College. There is a notion which rises sometimes even in thoughtful and educated minds in their dejected moods, and which perpetu- ates itself as a belief pretty extensively among the unthinking and ignorant, that we are living in times of great physical degeneracy; that the world is in its decay, and that we have had the misfortune to be produced in the decrepitude of Nature. It is suspected by some that the whole creation languishes, and that neither plants nor animals have the bulk or vigor of their ancestors, and that everything is daily sinking by gradual diminution. Though the process of deterioration is thus general, it is considered that in mankind the most striking failure of stature and strength and health and longevity is to be seen, and that this species has no brighter prospect, as things are now moving, than to go the way of those lamented fowls, the Dodo and the Great Auk. This opinion has the weight of great antiquity. The poetry of all ages is full of it. “ These degenerate days ” may be fixed, by the authority of contemporary writers, in almost every part of the historic period. Nor is it a fancy of the poets alone, for in what is left to us of the science of ancient Greece and Rome the same notion frequently recurs. I find in an old English author a pas- sage so exactly in point, that I cannot forbear to repeat it here. Dr. John Cains, a very learned man, the first of English physicians three hundred and twenty years ago, is trying to account for the “ sweating sickness ” of that time, one of the most fearful pesti- lences that ever visited any people. He says: “We are nowe a dales so unwisely fine, and womanly delicate, .... the olde manly hardness, and stoute courage, and peinfulnes of England is utterly driven awaye; insteade whereof men now a daies receive womanlines, and become nice, not able to withstande a blaste of wynde, or resist a poore fishe. And children be so brought up that if they be not all daie by the fire with a toste and butire, and in their furres, they be straight sick.” And he laments that peo- 2 CIVILIZATION AND HEALTH. pie no longer “ lyve quietlie, frlendlie, and merily one with another, as men were wont to do in the olde worlde, when this countrie was called merye Englande.” Yet in spite of these consuming vices, bringing swift destruction with them, that dreadful pest has gone, clean gone, and has been seen no more for these three cen- turies, and the English people remains —remains to be'scolded in the same round terms in this present year of grace; and to listen to tales of the lost prosperity and happiness of some golden age, fixed, if not wholly vague and dateless, in some period when, as Macaulay has said, in a passage familiar to all, “ noblemen were destitute of comforts the want of which would be intolerable to a modern footman ; when farmers and shopkeepers breakfasted on loaves, the very sight of which would raise a riot in a modern workhouse; when to have a clean shirt once a week was a privi- lege reserved for the higher class of gentry ; when men died faster in the purest country air, than they now die in the most pestilential lanes of our towns; and when men died faster in the lanes of our towns than they now die on the coast of Guiana.” Sagacious minds may have often suspected this cherished griev- ance of the ages to be an imaginary one, but only in recent times has it been possible to show authoritatively how unfounded it is. The gathering and recording of great masses of facts relating to the duration of human life is a modern practice. There is no continuous record of this sort running back quite four hundred years. The well-known and often quoted Geneva records are the oldest that we have. No one, probably, can see the result of those records stated for the first time without a sense of astonishment. They show us that in a period of three hundred years, the average term of life was lengthened from 21.21 years to 40.68 years, an increase of almost 100 per cent. So surprising a statement as this might well be received with suspicion, were it not that all the evi- dence that we have (and of later years it has accumulated enor- mously and with extreme particularity of detail) goes to corrob- orate it. The temptation is strong to set before you some of the impressive arithmetic of the subject, and leave it there, but “ the eloquence of figures ” addresses itself rather to sight than to hearing; and, besides, many of you must have seen a statement of the facts, at once full and exact, given in an article in late num- bers of the “ Atlantic Monthly.” 1 In short, we know that the ex- pectation of life for those born in Christendom is greater now than 1 “The Increase of Human Life,” by Dr. Edward Jarvis. Atlantic Monthly, October, November, and December, 1869. CIVILIZATION AND HEALTH. 3 ever before since history began to be written ; that life is better worth having now than ever before; that it is more respected, more fenced about with all safeguards of law, more secure. The growing reluctance to inflict death as a penalty, is a single indica- tion of this fact. So, more indirectly, is the growing intolerance of the existence of bodily pain. Where now could spectators be found for an auto dafe, or a crowd of connoisseurs of the torture- chamber ? Since the divine discovery of anaesthesia has shown us that the worst and most hopeless of pains are unnecessary and pre- ventable, we have had some education in this regard. It is still too early to estimate in full the moral effects of that discovery, nor is this the place to do it, but I shall scarcely be called fanciful for this suggestion of their importance. Admitting then, as we must, this steady increase in the term of human life coincident with the progress of our civilization, it be- comes us to know something in detail of the influences which have proved thus kindly and fostering. Can we simply say that all the new conditions to which man has been subjected in his progress from the primeval state up to the civilization of the pres- ent, have been to his advantage ? Far from it. Countless-myriads of men, some entire races, have been crushed and melted away in the working out of the great problem. “ The world,” says wise Sir Thomas Browne, “ that took but six days to make, is like to take six thousand years to make out, meanwhile old truths voted down begin to resume their places, and new ones arise upon us.” It is a slow process, our coming to a perfect understanding with Nature, so that, on the one hand, we take all that she has to give us, and get the good of it, and on the other hand, we do not inter- fere with her great changeless laws by our little housekeeping arrangements. Whenever we do this latter, whether by blunders in the way of our dwelling, or occupation, or food, or clothing, or med- icine, we invariably suffer for it. She will not be defrauded. The history of civilization is a recital of experiments that prove this. The human individual is an infinitely variable quantity, and it takes a great while to complete and determine important experiments upon him; so long sometimes that his own life is too short, and his heirs must carry ou the process after him. A much longer period is needed to get the final results of similar experiments upon the hu- man race. Now a steady succession of ever new experiments attends the progress of mankind, not only from absolute barbarism to civil- ization, but from one degree of civilization to another. When, for instance, the Irish people began to be fed with pure starch,— with 4 CIVILIZATION AND HEALTH. potatoes, that easily cultivated and prolific root was found to give great returns to the poorest husbandry in the cold and damp soil which had before reluctantly yielded scanty crops of rye and bar- ley. The people soon had a greater bulk of food than ever before to put into their stomachs, and the sense of distension thus pro- duced was satisfactory as replacing habitual emptiness. Popula- tion increased, not uniformly a symptom of prosperity, and the new and abundant food was regarded as a great boon to the im- poverished and ill-fed country. The potato gradually exterminated the grain crop. What the effect was then upon the health of the potato eaters, no one of that age seems to have observed. know now, for Majendie and Lehmann and Liebig have taught us, that this sort of feeding was no better than disguised starvation ; and, more recently, with the introduction of extensive potato cul- ture into new countries, New Zealand for example, we have had the opportunity of seeing how certain diseases of mal-nutri- tion have multiplied there. But the potato speedily became almost the sole food of Ireland, and nobody ventured to speak a disre- spectful word of the vegetable, until' Wm. Cobbett did, after two centuiies of its use ; and he was well known for a surly iconoclast and impracticable revolutionist, whom nobody regarded. So the experiment went on, and we know only too well what has come of it thus far. In other countries when wheat has failed, the poor, though sorely pinched, have made shift with barley and rye, and’ when these were gone, with buckwheat and roots; but where, in years of plenty, nothing stands between the people and death but the starvation diet of potatoes, what is the alternative when that fails ? This is the awful question that has been put again and again to the Irish in successive potato famines, and which, after a despairing attempt at answering it with poor pot-herbs, and dulse and tangle from the sea, they have “given up” by myriads. The potato played this people false, not merely by melting into rottenness beneath their grasp, but, more insidiously, by slowly sapping their physical and perhaps moral powers through genera- tions ; so that when the time of stress and struggle came, noth- ing was left in reserve of strength and courage, and the famine- typhus found them a passive prey.1 “ All analogy,” says Dr. 1H arr, the Registrar-General of England, “ proves that no exten- l That sainUy man, Father Matthew, said in 1846, “On the 27th July, I passed from Cork to Dublin, and this doomed plant bloomed in all the luxuriance of an abundant har- vest. Returning 3d August, I beheld with sorrow one wide waste of putrefying vegetation. In many places the wretched people were seated on the fences of their gardens, wringing their hands and wailing bitterly the destruction that had left them foodless.” 6 CIVILIZATION AND HEALTH. 5 sive or permanent degeneration of a race can be accomplished in less than two of three generations. The great change is as slow and insidious as it is certain. It is rarely perceived by its victims, who remain rooted and benumbed on the spot, unless they and the community are aroused by sudden and terrible catastrophes. That angel which it would seem it has pleased the Almighty Creator and Preserver of mankind to charge with this dread mission, is the pestilence. Wherever the human race, yielding to ignorance, in- dolence, or accident, is in such a situation as to be liable to lose its strength, courage, liberty, wisdom, lofty emotions, the plague, fever, or cholera comes, not committing havoc perpetually, but turning men to destruction, and then suddenly ceasing, that they may consider. As the lost father speaks to the family, and the slight epidemic to the city, so the pestilence speaks to nations, in order that greater calamities than the untimely death of the popu- lation may be avoided,” We cannot say confidently yet, that we have seen the ultimate result of this potato experiment. Take an instance, again, in the case of another vegetable un- known to the Old World, American, too, like the potato, but this time a tremendous narcotic. Tobacco has been a factor in our civilization for about as long a time as the potato. Precisely what it has done to the human race, we are not yet authorized to say. Some of its effects are very subtle; but that it has had some great influence seems clear enough. When it is taken for the first time in a considerable dose, it produces symptoms which need not be described here, but of which we may safety say, that no physician could see them origi- nating in any case without alarm, if ignorant of the cause produ- cing them ; and, having such properties, this drug is consumed by the human family at the estimated rate of nearly one thousand millions of pounds a year. Its effects cannot fail to have been great, however uncertain, and we have some good reasons for be- lieving that in many cases they outlast the life of the individual in whom they are first manifested; that, for instance, what is impaired assimilation in the parent is arrested or perverted development in the child, that nervous irritability and hypochondria in the one becomes paralysis and insanity in the other; and, in short, that this tobacco experiment is one of those already spoken of, that can- not be carried through in a single individual or a single genera- tion. Undoubtedly posterity will know more about it than we do, and perhaps will wonder at our ignorance of what to them will be palpable facts. 6 CIVILIZATION AND HEALTH. Then, again, there are coffee and tea, still newer to our use. In the year 1610, Master George Sandys saw with astonishment in Constantinople the Turks “ sitting most of the day apd sipping of a drink called coffa (of the berry that it is made of) in little china dishes, as hot as they can suffer it, blacke as soote, and tasting not much unlike it, which helpeth, as they say, digestion, and procureth alacrity.” And this, he speculates, is the gen- uine “ blacke broth ”of the old Spartans. In 1652 the first little parcel of it was brought to London and used. This present year, it is calculated, in Europe and America, something one hun- dred and fifty thousand tons is consumed (three hundred million pounds). September 25, 1661, the worthy Mr. Pepys, a great fancier of novelties, makes the important entry in Ins, diary : “ I did send for a cup of tea, a China drink, of which -I
