According to Sigmund Freud, the ego is part of personality that mediates the demands of the id, the superego and reality. The ego prevents us from acting on our basic urges (created by the id), but also works to achieve a balance with our moral and idealistic standards (created by the superego).
In philosophy, egoism is the theory that oneâs self is, or should be, the motivation and the goal of oneâs own action. Egoism has two variants, descriptive or normative. The descriptive (or positive) variant conceives egoism as a factual description of human affairs.
