The difficulties attendant on theories such as those of Mr. Murphy and Mr. Wallace, and the unsatisfactory explanation afforded by the theory of evolution, as usually understood, of the origin of man, have led me to the opinion that nature as a whole is organic, and that man is the necessary result of its evolution. Not only so, however; man must be viewed as the real object of the evolution of nature viewed as a living organism. Without him nature itself would be imperfect, and all lower animal forms must, therefore, be considered as subsidiary to the human organism, and as so many stages only towards its attainment. But if living nature is an organic whole, its several parts must be intimately connected. Hence the numerous correspondences between man and the higher mammals cannot be accidental or even merely designed similarities. They betoken an actual and intimate connection between the organisms presenting them, and such an one as is consistent only with a derivation of one from the other. This view differs from that of Mr. Darwin, not in the fact of man’s derivation from the ape, but in the mode and conditions under which it has taken place. Derivation, by virtue of an inherent evolutional impulse, is totally different from simple descent, aided by natural selection. In the latter case the appearance of man may be described as in some sense accidental; in the former, not only is it necessary, but it is that for which all evolution has taken place, the only condition, in fact, under which evolution was possible.
