with the consideration of his further development and his diffusion over the surface of the globe.
The mental qualities which have developed in Man, though traceable in a vague and rudimentary condition in some of his animal associates, are of such an unprecedented power and so far dominate everything else in his activities as a living organism, that they have to a very large extent, if not entirely, cut him off from the general operation of that process of Natural Selection and survival of the fittest which up to their appearance had been the law of the living world. They justify the view that Man forms a new departure in the gradual unfolding of Nature's predestined scheme. Knowledge, reason, self-consciousness, will, are the attributes of Man. It is not my purpose to attempt to trace their development from lower phases of mental activity in man's animal ancestors, nor even to suggest the steps by which that development has proceeded. What we call the will or volition of Man—a discussion of the nature and limitation of which it would be impossible for me here to offer and is happily not necessary for my present purpose—has become a power in Nature; an imperium in imperio, which has profoundly modified not only man's own history but that of the whole living world and the face of the planet on which he exists. Nature's inexorable discipline of death to those who do not rise to her standard—survival and parentage for those alone who do—has been from the earliest times more and more definitely resisted by the will of Man. If we may for the purpose of analysis, as it were, extract man from the rest of Nature of which he is truly a product and part, then we may say that
