Egoism is a philosophical concept that emphasizes self-interest as the foundation of moral behavior. It suggests that individuals should act in ways that promote their own well-being and happiness. This perspective can be seen in various forms, including ethical egoism, which argues that it is morally right to prioritize one's own needs, and psychological egoism, which posits that people naturally act in their own self-interest. Critics of egoism argue that it can lead to selfishness and disregard for others' needs. They believe that a more balanced approach, such as altruism, which focuses on the welfare of others, is essential for a harmonious society. The debate between egoism and altruism continues to be a significant topic in ethics and philosophy.
