Superego

In psychoanalytic theory, the superego is the agency of the psychic apparatus that internalises the norms, prohibitions and moral ideals of society, acting as a judge and censor of the individual's conduct and desires.

Sigmund Freud formulated the notion within his structural model of the mind, first outlined in Beyond the Pleasure Principle (1920) and developed chiefly in The Ego and the Id (1923). Freud's German term, das Über-Ich, literally means "the over-I"; the Latinised form superego was adopted in the English-speaking world through the translation of James Strachey. For Freud, the superego forms in childhood, largely through the identification with parental figures and the assimilation of their demands and prohibitions. This is why it is partly unconscious, and why its commands can remain severe in ways that do not always match a person's conscious values. Its most characteristic function is to produce guilt and self-criticism, as well as to set ideals.

The superego occupies a position between the id, where the drives are concentrated, and the ego, which mediates between those drives, reality and moral demands. While the id follows the pleasure principle and the ego the reality principle, the superego upholds standards of conduct that often oppose immediate gratification. Freud later distinguished two components within it: the conscience, which punishes with feelings of guilt, and the ego-ideal, which points toward models of perfection.

A simple example would be a person who feels intense remorse for a desire they never acted upon: in the Freudian reading, that distress comes from the severity of an internalised moral agency rather than from an explicit, conscious rule.

The concept has been the subject of continuing debate. Post-Freudian authors such as Melanie Klein and Anna Freud reinterpreted it in relation to early childhood and defence mechanisms. Other critics have questioned its universality, noting that morality is shaped differently across cultures, or that the structural theory is hard to test empirically. In contemporary psychology the notion remains an important historical reference, though it has largely been replaced by cognitive and moral-development models that do not posit a separate psychic agency.
