§ 95. What must be the accompanying evolution of conduct? What must the relations between egoism and altruism become as this form of nature is neared? A conclusion drawn in the chapter on the relativity of pleasures and pains, and there emphasized as one to be borne in mind, must now be recalled. It was pointed out that, supposing them to be consistent with continuance of life, there are no activities which may not become sources of pleasure, if surrounding conditions require persistence in them. And here it is to be added, as a corollary, that if the conditions require any class of activities to be relatively great, there will arise a relatively great pleasure accompanying that class of activities. What bearing have these general inferences on the special question before us? That alike for public welfare and private welfare sympathy is essential we have seen. We have seen that co-operation and the benefits which it brings to each and all, become high in proportion as the altruistic, that is the sympathetic, interests extend. The actions prompted by fellow-feeling are thus to be counted among those demanded by social conditions. They are actions which maintenance and further development of social organization tend ever to increase, and, therefore, actions with which there will be joined an increasing pleasure. From the laws of life it must be concluded that unceasing social discipline will so mold human nature that eventually sympathetic pleasures will be spontaneously pursued to the fullest extent advantageous to each and all. The scope for altruistic activities will not exceed the desire for altruistic satisfactions. In natures thus constituted, though the altruistic gratifications must remain in a transfigured sense egoistic, yet they will not be egoistically pursued--will not be pursued from egoistic motives. Though pleasure will be gained by giving pleasure, yet the thought of the sympathetic pleasure to be gained will not occupy consciousness, but only the thought of the pleasure given. To a great extent this is so now. In the truly sympathetic, attention is so absorbed with the proximate end, others' happiness, that there is none given to the prospective self-happiness which may ultimately result. An analogy will make the relation clear.
