“Foucault located the disciplinary societies in the eighteenth and nineteenth centuries; they reach their height at the outset of the twentieth. They initiate the organization of vast spaces of enclosure. The individual never ceases passing from one closed environment to another, each having its own laws: first, the family; then the school (“you are no longer in your family”); then the barracks (“you are no longer at school”); then the factory; from time to time the hospital; possibly the prison, the pre-eminent instance of the enclosed environment. It’s the prison that serves as the analogical model: at the sight of some laborers, the heroine of Rossellini’s Europa ’51 could exclaim, ‘I thought I was seeing convicts.’”
