Repression

Repression is the defense mechanism that Freud considered the cornerstone of the entire psychoanalytic edifice. It consists of the active but unconscious exclusion of thoughts, memories, impulses, or fantasies that generate intolerable anxiety. Unlike suppression, which is a conscious and voluntary process, repression operates entirely outside the subject's awareness.

Freud developed the concept of repression from his clinical observations of hysterical patients in the 1890s. He noticed that symptoms often disappeared when patients managed to recall and verbalize previously inaccessible traumatic experiences. This led him to postulate repression as the primary mechanism by which disturbing material is kept out of consciousness.

Repression does not eliminate the repressed material — it merely displaces it to the unconscious, from where it continues to exert influence on behavior, dreams, parapraxes, and neurotic symptoms. The psychic energy required to maintain repression explains the fatigue and life restriction often observed in people with massive repressions. Psychoanalytic therapy seeks to make the repressed material conscious in order to liberate this energy.
