Freud's psychoanalytic theories
The superego, which develops around age four or five, incorporates the morals of society.  Freud believes that the superego is what allows the mind to control its impulses that are looked down upon morally.  The superego can be considered to be the conscience of the mind because it has the ability to distinguish between reality as well as what is right or wrong.  Without the superego Freud believes people would act out with aggression and other immoral behaviors because the mind would have no way of understanding the difference between right and wrong.  The superego is considered to be the “consciousness” of a person’s personality and can override the drives from the id. Freud separates the superego into two separate categories: the ideal self and the conscious.  The conscious contains ideals and morals that exist within society that prevent people from acting out based on their internal desires.  The ideal self contains images of how people ought to behave according to society's ideals.
