Id, Ego and Superego

by email icon published

Perhaps Freud's single most enduring and important idea was that the human psyche (personality) has more than one aspect. Freud (1923) saw the psyche structured into three parts (i.e. tripartite), the id, ego and superego, all developing at different stages in our lives.

These are systems, not parts of the brain, or in any way physical.

id ego and superego

The id (or it)

The Ego (or I)

The Superego (or above I)
