Society Must Be Defended is taken from a series of lectures given by Foucault at the Collége de France in 1975-76. Using war to analyse power relations, he contends that politics is ultimately a continuation of battlefield violence, and that ingrained ideas of sovereignty and individual rights are attempts to refute the fact that all power relations are based on domination. Coloured with brilliant historical examples, Foucault draws from many periods in both England and France, with wonderful digressions into subjects as diverse as classical French tragedy and the gothic novel.
