What does the term river stage mean? Water science questions and answers, from the USGS Water Science School
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).
Ego [edit]. The ego (Latin I) acts according to the reality principle; i.e. it seeks to please the id's drive in realistic ways that will benefit in the long term rather than bring grief. At the same time, Freud concedes that as the ego attempts to mediate between id and reality, it is often obliged to cloak the Ucs.
