What was discovered

Freud introduced in 'Beyond the Pleasure Principle' (1920) and formalized in 'The Ego and the Id' (1923) a new three-part model of the psyche: the id (unconscious impulses), the superego (internalized moral norms) and the ego (which mediates between them and reality). It replaced his earlier topographical model (conscious/preconscious/unconscious) and became the core of classical psychoanalysis.

What it led to

  • Psychoanalytic diagnosis based on conflicts between psychic agencies
  • Modern neuropsychoanalysis

Built on

  • Freud's earlier topographical model (conscious, preconscious, unconscious)
