Instead of recognizing this contrast, most readers will be inclined to identify a moral life with a life little varied in its activities. But here we come upon a defect in the current conception of morality. This comparative uniformity in the aggregate of motions, which goes along with morality as commonly conceived, is not only not moral but is the reverse of moral. The better a man fulfills every requirement of life, alike as regards his own body and mind, as regards the bodies and minds of those dependent on him, and as regards the bodies and minds of his fellow-citizens, the more varied do his activities become. The more fully he does all these things, the more heterogeneous must be his movements. One who satisfies personal needs only, goes through other things equal, less multiform processes than one who also administers to the needs of wife and children. Supposing there are no other differences, the addition of family relations necessarily renders the actions of the man who fulfills the duties of husband and parent, more heterogeneous than those of the man who has no such duties to fulfill, or, having them, does not fulfill them; and to say that his actions are more heterogeneous is to say that there is a greater heterogeneity in the combined motions he goes through. The like holds of social obligations. These, in proportion as a citizen duly performs them, complicate his movements considerably. If he is helpful to inferiors dependent on him, if he takes a part in political agitation, if he aids in diffusing knowledge, he, in each of these ways, adds to his kinds of activity--makes his sets of movements more multiform; so differing from the man who is the slave of one desire or group of desires. Though it is unusual to consider as having a moral aspect, those activities which culture involves, yet to the few who hold that due exercise of all the higher faculties, intellectual and æsthetic, must be included in the conception of complete life, here identified with the ideally moral life, it will be manifest that a further heterogeneity is implied by them. For each of such activities, constituted by that play of these faculties which is eventually added to their life-subserving uses, adds to the multiformity of the aggregated motions. Briefly, then, if the conduct is the best possible on every occasion, it follows that as the occasions are endlessly varied the acts will be endlessly varied to suit--the heterogeneity in the combinations of motions will be extreme. § 28. Evolution in conduct considered under its moral aspect, is, like all other evolution, toward equilibrium. I do not mean that it is toward the equilibrium reached at death, though this is, of course, the final state which the evolution of the highest man has in common with all lower evolution; but I mean that it is toward a moving equilibrium.
