Michel Foucault spent his career attacking the limits he saw everywhere: in language, in institutions, in the categories societies use to sort the sane from the mad and the lawful from the criminal. This 1993 documentary traces that project alongside his life, moving through his studies of asylums and prisons and the ideas that made him one of the most cited and most argued-over thinkers of the twentieth century. Interviews and archival material cover his early work on madness and civilization, his history of the prison system, and the later writings on sexuality that extended his argument about power into the most private corners of daily life. The film does not soften the controversy that followed him, treating his personal life and his politics as part of the same restless refusal to accept inherited categories. What emerges is a portrait of a philosopher who kept redefining his own subject, from historian of institutions to theorist of power itself, and who left later thinkers still fighting over what he actually meant.
