Public torture gave way to discipline, not to mercy

Foucault opens by describing the elaborate public executions of early modern Europe, ritualized spectacles of torture designed to display the sovereign's absolute power over the condemned body in front of a crowd. He then documents the relatively rapid decline of these spectacles by the early nineteenth century, replaced by more private, standardized forms of imprisonment. His key claim is that this shift is usually told as a story of enlightenment and growing compassion, but he argues it is better understood as a change in the efficiency and target of power. Public torture was actually a fragile technology, prone to provoking sympathy for the condemned or riots against the authorities administering it. Discipline, by contrast, works continuously and invisibly on the mind and habits rather than through occasional dramatic violence on the body, making it a more reliable and pervasive tool of control even though it looks gentler on the surface. Takeaway: less visible punishment can still mean more total, more effective control.
