Michel Foucault 1926 – 1984

Michel Foucault was a 20th-century French philosopher, historian, and social theorist, one of the most influential figures of post-war continental philosophy. His major works, including Madness and Civilisation, The Order of Things, Discipline and Punish, and the multi-volume History of Sexuality, traced the historical conditions under which categories such as madness, illness, criminality, and sexuality came to take their modern forms. He developed the concepts of episteme, discourse, biopower, and governmentality to analyse how knowledge and power are intertwined in modern institutions and practices. He held a chair at the College de France from 1970 until his death and was for the last decade of his life one of the most public intellectuals in France. His work has been formative for post-structuralism, queer theory, postcolonial studies, and contemporary political philosophy.

Michel Foucault (1926–1984) was the most influential French philosopher of the late twentieth century and the central figure of post-structuralist thought. Born in Poitiers, he studied at the École Normale Supérieure with Althusser, took chairs in Paris and Tunis, and from 1970 held the chair in the History of Systems of Thought at the Collège de France, where his annual lecture courses became major intellectual events.

Foucault's mature work consists of historical-philosophical investigations of how specific institutions, practices, and discourses produce the modern subject. Madness and Civilization (1961) traces the formation of the category of madness in early modern Europe. The Birth of the Clinic (1963) examines the formation of modern medical perception. Discipline and Punish (1975) analyzes the shift from sovereign power's spectacular punishments to disciplinary power's normalizing surveillance. The History of Sexuality, of which three volumes appeared in his lifetime, examines how sexuality was constituted as a domain of knowledge and an axis of subject-formation.

Foucault's methodological framework — genealogy, archaeology, the analysis of power-knowledge — shaped not only philosophy but history, sociology, queer theory, and the wider humanities. He died of complications from AIDS in 1984; the fourth volume of the History of Sexuality, on early Christian sexual ethics, was published posthumously in 2018. His political activity — on prisoner rights, the GIP, the Iranian revolution — has remained as contested as the philosophy.
