"610Tv ¥) Science 142 (1963) 1126. Exobiology Several sources have privately sug. gested a new journal on “exobiology,” the study of extraterrestrial life, My profound objections are not to their optimism; but the field is too impor. tant to be sequestered. The policy issues. of interplanetary quarantine and of large-scale expenditures in scientific programs deserve the widest critical at. tention; so do scientific questions that range from the origin of life to the extraction of interstellar signals from cosmic noise. A specialized journal would only isolate the field from the badly needed critical judgments of 4 scientific community which, in the main, is not primarily preoccupied with exobiology. The merits of this proposal apart, it points up a serious problem in our Sys- tem of communication. The motivation for a new journal is a variable mix. ture of idealistic enthusiasm, ego- gratification, capitalistic enterprise, and rebellion against the critical judgements of the existing establishment. Owing to the operation of the copyright laws (which here convert a common good into a private interest), the proponents of a journal have a unique advantage, whatever their motivation. At least ac. cording to present custom we are morally accountable for its content ac. cording to our profession: If our soci. etics continue to abdicate their respon. sibility for scientific communications, the successors will not always be 50 scrupulous.
