In contrast to the instinctual id and the moral superego, the ego is the rational, pragmatic part of our personality. It is less primitive than the id and is partly conscious and partly unconscious.
According to Freud's psychoanalytic theory of personality, the superego is the component of personality composed of our internalized ideals that we have acquired from our parents and society. The superego works to suppress the urges of the id and tries to make the ego behave morally, rather than realistically.
