Id, ego, and super-ego - Wikipedia, the free encyclopedia

In Freud's theory, the ego mediates among the id, the super-ego and the external world. Its task is to find a balance between primitive drives and reality (the Ego devoid of morality at this level) while satisfying the id and super-ego. Its main concern is with the individual's safety and allows some of the id's desires to be expressed, but only when consequences of these actions are marginal.
