Jacques Lacan

Jacques Lacan (Paris, 1901–1981) was a French psychiatrist and psychoanalyst, one of the most influential and controversial figures in twentieth-century psychoanalysis. His thought belongs to the Freudian tradition, but he reread Freud in light of philosophy, structural linguistics and mathematics, which made him a reference point for structuralism and post-structuralism. He matters both for his account of the unconscious and for the debate he opened within psychoanalysis itself.

Born into a Catholic, middle-class family in Paris, Lacan turned in his youth to Spinoza and Nietzsche, and this reading led him to give up religious faith. He studied medicine at the University of Paris and specialised in psychiatry, working under Henri Claude at the Sainte-Anne Hospital and under Gaëtan Gatian de Clérambault at the police prefecture's infirmary. In 1932 he defended his doctoral thesis on paranoid psychosis, built around the case of a patient he called Aimée. In those years he moved in the Surrealist circle of André Breton and Salvador Dalí, and he was himself in analysis with Rudolph Loewenstein. He joined the Paris Psychoanalytical Society in 1934 and became a full member in 1938, although his philosophical reading of Freud drew opposition from much of the institution.

After the Second World War, Lacan gave seminars regularly from 1953 to 1980, first at Sainte-Anne, then at the École Normale Supérieure and finally at the Faculty of Law, opposite the Panthéon. His call for a «return to Freud» and his opposition to ego psychology led to a split in the Paris society in 1953. He then founded the École Freudienne de Paris, which he himself dissolved in 1980 after internal disputes. His Écrits, published in 1966, brought him wide recognition in France.

His central idea is that the unconscious is structured like a language, so that desire is articulated through signifiers. He also proposed the mirror stage, in which the child recognises itself in its image and forms an early identity marked by alienation, and he reformulated the Oedipus complex as a symbolic function tied to the law. His texts are dense and deliberately enigmatic, and readers have debated for decades how to interpret them.

His influence reaches well beyond the clinic. His ideas shaped linguistics, film theory, literary criticism and parts of feminist thought. He remains a controversial figure: his clinical innovations and his expulsion from the International Psychoanalytical Association left a legacy divided between those who see him as a major renewer of Freud and those who reject him.
