Michel Foucault

Michel Foucault (1926–1984) was a French philosopher whose work transformed the study of power, knowledge, and subjectivity. His analyses of prisons, psychiatry, sexuality, and governance showed that modern institutions do not simply constrain pre-existing subjects but produce the subjects they govern — that power operates not primarily through prohibition but through the constitution of what counts as normal, healthy, rational, and human.

Core ideas

• Power/knowledge: Foucault argued that power and knowledge are not separable — that the production of knowledge is always already an exercise of power, and that power operates through the production and circulation of knowledge. The human sciences (psychiatry, criminology, sociology) do not merely study their objects; they constitute them. “The madman,” “the criminal,” “the pervert” are not categories that exist prior to the knowledge that describes them — they are produced through the practices of examination, classification, and treatment.
• Disciplinary power: in Discipline and Punish (1975), Foucault analyzed how modern societies shifted from sovereign power (the spectacle of punishment) to disciplinary power (the normalization of behavior). Discipline operates through surveillance, examination, and the production of docile bodies — subjects who internalize the norms they are measured against. The panopticon — a prison designed so that inmates never know when they are being watched — is the architectural figure of disciplinary power.
• Biopolitics: in his later lectures, Foucault introduced biopolitics — the governance of populations through the management of life itself. Where disciplinary power targets individual bodies, biopolitics targets populations: birth rates, mortality, health, hygiene, reproduction. The modern state governs by making live and letting die — by managing the biological life of populations rather than threatening them with death.
• Governmentality: Foucault’s concept of governmentality names the ensemble of institutions, procedures, calculations, and tactics that allow the exercise of power over populations. Governmentality is not reducible to the state; it includes all the techniques — educational, medical, economic, pastoral — through which conduct is conducted.
• Discourse: systems of language and practice that define what counts as knowledge in a domain. Discourse is not merely language about a topic but the structure that determines what can and cannot be said, thought, and known about it.
• Genealogy: a method for tracing how concepts are produced through contingencies, institutions, and power relations — revealing that what appears natural and necessary is historical and contingent.
