Society Must Be Defended is Michel Foucault's devastating critique of the systems of power and control inherent in civilization. Taken from a series of lectures given by Foucault at the Collége de France in 1975-76, it reveals how war is the foundation of all power relations, and politics ultimately a continuation of battlefield violence. He offers a politically charged re-reading of history, with examples ranging from the Trojan myth to Nazi Germany, to show a continual, 'silent war' between the powerful and the powerless.
