What is the relevance of anarchist thought for politics and political theory today? While many have dismissed anarchism in the past, Saul Newman contends that anarchism's heretical critique of authority, and its insistence on full equality and liberty, places it at the forefront of the radical political imagination today. With the unprecedented expansion of state power in the name of security, the current 'crisis of capitalism' and the terminal decline of Marxist and social democratic projects, it is time to reconsider anarchism as a form of politics. This book seeks to renew anarchist thought through the concept of postanarchism.
