Egoism

In philosophy, egoism is the theory that one’s self is, or should be, the motivation and the goal of one’s own action. Egoism has two variants, descriptive or normative. The descriptive (or positive) variant conceives egoism as a factual description of human affairs. That is, people are motivated by their own interests and desires, and they cannot be described otherwise. The normative variant proposes that people should be so motivated, regardless of what presently motivates their behavior. Altruism is the opposite of egoism. The term “egoism” derives from “ego,” the Latin term for the English word “I”. “Egoism” should be distinguished from “egotism,” which means a psychological overvaluation of one’s own importance, or of one’s own activities.
