The Hidden Mind
Psychoanalysis, founded by Sigmund Freud in the late 19th century, proposed that much of human behavior is driven by the unconscious mind — thoughts, urges, and memories inaccessible to conscious awareness but still shaping feeling and action. Freud modeled the psyche as three interacting systems: the Id (innate biological drives, operating on the "pleasure principle"), the Ego (the rational mediator, operating on the "reality principle"), and the Superego (internalized moral standards). Conflict among the three, especially repression of forbidden sexual or aggressive impulses, was thought to generate anxiety and, if unresolved, psychological symptoms.
Freud also proposed a sequence of psychosexual stages — Oral, Anal, Phallic, Latency, and Genital — arguing that unresolved conflict at any stage could leave a lasting "fixation" shaping adult personality. To manage anxiety, Freud proposed the ego relies on defense mechanisms: repression (pushing a threatening thought out of awareness entirely), projection (attributing one's own unacceptable impulse to someone else), and sublimation (redirecting an impulse into a socially valued activity), among others.
| System | Governing principle |
|---|---|
| Id | Pleasure principle — wants immediate gratification |
| Ego | Reality principle — mediates between id, superego, and the world |
| Superego | Morality principle — internalized rules and ideals |
Freud's inner circle later split over his heavy emphasis on sexuality: Carl Jung broke away to develop analytical psychology, centered on a collective unconscious of shared archetypes, while Alfred Adler developed individual psychology, centered on feelings of inferiority and the drive to compensate for them.
Common pitfall: treating "defense mechanism" as a sign of weakness or dishonesty. In Freud's model, defense mechanisms are a normal, universal function of the ego — everyone uses them to manage anxiety; only their rigidity or extremity becomes a clinical concern.
