egoism (ēˈgōĭzəm) [key], in ethics, the doctrine that the ends and motives of human conduct are, or should be, the good of the individual agent. It is opposed to altruism, which holds the criterion of morality to be the welfare of others. The term has been variously used, from the benevolent self-interest of the utilitarians to the belief, articulated by Friedrich Nietzsche, that all altruistic sentiment is cowardice. Egoism is frequently associated with the ethics of the early Greek hedonists. Some modern philosophers attempt to reconcile egoism and altruism by adducing the concept of the growing self who invests his interests in an ever-widening field.
