Superego

In Freudian psychoanalytical theory, a component of the tripartite model of the psychic apparatus that concerns ethical and moral conduct.  In this respect, it is a sort of arbitrator of the ego, which originates from a conflict between the id and the ego during development.  And during development, according to Freud, it emerges as a consequence of overcoming the Oedipal complex.  As such, it has been depicted as the descendant of this complex.
