In ethical philosophy, rational egoism (also called rational selfishness or egotism) is the principle that an action is rational if and only if it maximizes one's self-interest. The view is a normative form of egoism. However, it is different from other forms of egoism, such as ethical egoism and psychological egoism. While psychological egoism is about motivation and ethical egoism is about morality, rational egoism is a view about rationality (where rationality may or may not be tied to morality). Ethical egoism is also different from amoralism.
