In explanation of this ordering of his interests, he said that he always had had a predilection for History, but that a man who needs a philosophy must get it fixed before he can properly do anything else. It is to be presumed, however, that he was also attracted to Philosophy by the fight for Evolution, by his intimacy with Youmans and Spencer, and perhaps most of all, by the appeal to a mind that, in spite of his enjoyment of the good things of life, was at bottom profoundly religious. All this involved his strong conviction of the need of building up the religious implications of Evolution, to take the place of the old sanctions which, in many minds, Evolution had set aside. Fiske also contributed one generalization to our knowledge of biologic evolution, and that is a good deal for any man to do: many have attained fame for less. It was a generalization so important that Darwin regretted not having developed it himself. The contribution was, as most of our readers know, regarding the effect of long infancy upon psychic, and hence upon social, development. The reasons, when suggested, are as obvious as Columbus's egg: they are, of course, the aid to the evolution of the family and of altruism. When, after Fiske had done his best on these themes, and Evolution in History became the study of his life, in that work he was a pioneer, and probably as well fitted for it as any man that ever lived. His cutting off in the midst of his plans, before he was sixty, was one of those disasters and apparent wastes which are among the great puzzles of the Universe. * * * * *
