(1) Enough has been said above to show that egoism is not inevitable, but that men actually are influenced by motives which cannot be regarded as egoistic. It is, hence, not necessary to dwell upon this point. (2) As to the naturalness of egoism. Both the professional moralist and the man in the street may hesitate to admit that a man should neglect his own interests, and may find it natural that he should cultivate them assiduously. But it is only the exceptional man who maintains that he should have nothing else in view. There are individuals so constituted that self-interest makes to them a peculiarly strong appeal. Others, more social by nature, may be misled by psychological theory to maintain that a man's chief and only end is his own "satisfaction." [Footnote: See below, chapter xxvi, 3.] Still others, realizing that both one's own interests and the interests of one's neighbor are natural and seemingly legitimate objects of regard, are perplexed as to the method of reconciling their apparently conflicting claims, and are betrayed into inconsistent utterances. But it is too much to say that the professional moralist and the plain man normally regard pure egoism with favor and find it natural. In spite of our cynical maxims and our inclination to seek for ulterior motives for apparently altruistic acts, we abhor the thorough-going egoist, and we are not inclined to look upon the phenomena, let us say, of the family life, as manifestations of self-seeking. It is worth while to remark that, even if the approach to the Cyrenaic ideal were so common as not to seem wholly unnatural, that would not prove that it ought to be embraced; it is natural for men to err, but that does not make error our duty. (3) By the moral conviction of organized humanity, as expressed in custom, law, and public opinion, egoism stands condemned. Neither in savage life nor among civilized peoples, neither in the dawn of human history nor in its latest chapters, do we find these agencies encouraging every man to live exclusively for himself. Egoistic impulses are recognized, in that reward and punishment are allotted, but the end urged upon the attention of the individual is the common good, not his own particular good. The social conscience has always demanded of the individual self- sacrifice, even to the extent of laying down his life, on occasion, for the public weal. And the enlightened social conscience does not regard a man as truly moral whose outward conformity to moral laws rests solely upon a basis of egoistic calculation. The very existence of the family, the tribe, the state, is a protest against pure egoism. Were all men as egoistic as Aristippus seems to have professed to be, a stable community life of any sort would be impossible.
