Evolution of Self-Consciousness

It has come to be understood, and very generally allowed, that the conception of the origin of man as an animal race, as well as the origin of individual men within it, in accordance with the continuity of organic development maintained in the theory of evolution, does not involve any very Serious difficulties, or difficulties so great as are presented by any other hypothesis of this origin, not excepting that of "special creation "; - if that can be properly called a hypothesis, which is, in fact, a resumption of all the difficulties of natural explanation, assuming them to be insuperable and summarizing them under a single positive name. Yet in this evolution, the birth of self-consciousness is still thought by many to be a step not following from antecedent conditions in "nature," except in an incidental manner, or in so far only as "natural" antecedents have prepared the way for the "supernatural" advent of the self-conscious soul.
