Ethical egoism is a moral theory that suggests individuals should act in their own self-interest. According to this view, actions are considered morally right if they promote one's own well-being. This perspective emphasizes personal responsibility and the idea that prioritizing one's own needs can lead to better outcomes for society as a whole. Proponents of ethical egoism argue that when people pursue their own interests, they inadvertently contribute to the common good. Critics, however, contend that this approach can lead to selfishness and disregard for others. Overall, ethical egoism raises important questions about the balance between self-interest and altruism in moral decision-making.
