To assume that egoistic pleasures may be relinquished to any extent, is to fall into one of those many errors of ethical speculation which result from ignoring the truths of biology. When taking the biological view of ethics we saw that pleasures accompany normal amounts of functions, while pains accompany defects or excesses of functions; further, that complete life depends on complete discharge of functions, and therefore on receipt of the correlative pleasures. Hence, to yield up normal pleasures is to yield up so much life; and there arises the question--To what extent may this be done? If he is to continue living, the individual _must_ take certain amounts of those pleasures which go along with fulfillment of the bodily functions, and _must_ avoid the pains which entire non-fulfillment of them entails. Complete abnegation means death; excessive abnegation means illness; abnegation less excessive means physical degradation and consequent loss of power to fulfill obligations, personal and other. When, therefore, we attempt to specialize the proposal to live not for self-satisfaction but for the satisfaction of others, we meet with the difficulty that beyond a certain limit this cannot be done. And when we have decided what decrease of bodily welfare, caused by sacrifice of pleasures and acceptance of pains, it is proper for the individual to make, there is forced on us the fact that the portion of happiness, or means to happiness, which it is possible for him to yield up for redistribution, is a limited portion. Even more rigorous on another side is the restriction put upon the transfer of happiness, or the means to happiness. The pleasures gained by efficient action--by successful pursuit of ends, cannot by any process be parted with, and cannot in any way be appropriated by another. The habit of arguing about general happiness sometimes as though it were a concrete product to be portioned out, and sometimes as though it were co-extensive with the use of those material aids to pleasure which may be given and received, has caused inattention to the truth that the pleasures of achievement are not transferable. Alike in the boy who has won a game of marbles, the athlete who has performed a feat, the statesman who has gained a party triumph, the inventor who has devised a new machine, the man of science who has discovered a truth, the novelist who has well delineated a character, the poet who has finely rendered an emotion, we see pleasures which must, in the nature of things, be enjoyed exclusively by those to whom they come. And if we look at all such occupations as men are not impelled to by their necessities--if we contemplate the various ambitions which play so large a part in life; we are reminded that so long as the consciousness of efficiency remains a dominant pleasure, there will remain a dominant pleasure which cannot be pursued altruistically but must be pursued egoistically.
