Whose Psychology Founded Psychoanalysis?

Sigmund Freud, an Austrian neurologist, developed psychoanalysis through clinical work with patients suffering from "hysteria" and other neurotic conditions. His key theories include: the existence of an unconscious mind containing repressed desires and memories; the id, ego, and superego as components of personality; psychosexual development stages (oral, anal, phallic, latent, genital); the Oedipus complex; dream interpretation as the "royal road to the unconscious"; and defence mechanisms like repression, projection, and sublimation. His therapeutic method — free association (patients saying whatever comes to mind) while lying on a couch — established the "talking cure" as a treatment approach. While many of Freud specific theories (particularly regarding sexuality, femininity, and developmental stages) have been modified or abandoned by modern psychology, his broader insights about unconscious processes, the importance of early experiences, and the therapeutic value of exploring inner life remain foundational. His influence on art, literature, philosophy, and popular culture is immeasurable.
