The theory of evolution transforms intuitionism by the way in which it connects the individual with the race. Its first effect upon egoism is similar. The nature of the individual man as now exhibited is widely different from that which the older individualistic theory used to deal with. The latter is typified by the marble statue to which Condillac[118] compares the percipient subject, as yet unaffected by sense-impressions. The variety of mental life which is actually met with is accounted for by the different kinds of experiences different men pass through; and the consequent difference in the sources of pleasure and pain accounts for the diverse lines of activity which human beings follow out. But the theory of evolution shows that human nature is infinitely varied, not only through the variety of circumstances, but through the variety of inherited dispositions. One individual is not merely connected with others through considerable similarity of experience built upon an equally characterless basis; but he is organically related to all the members of the race, not only bone of their bone and flesh of their flesh, but mind of their mind. He is connected with others by a thousand subtly interwoven threads of emotion which enter into his life, and unite his desires and activities with the functions of the larger organism of which he is a member.
