"On Anarchism" is a necessary introduction to the political theory of Noam Chomsky. The book illuminates the foundations of Chomsky's thinking, specifically the continuous questioning of the legitimacy of established authority. It gathers essays and interviews to offer a brief, accessible introduction to his characteristically optimistic version of anarchism. It deconstructs the notion of anarchism as a fixed idea and challenges the traditional lines between anarchism and socialism. This book is sure to provoke, challenge, and inspire. Extremely relevant to our times, it is a reference for political activists and anyone interested in deepening their understanding of anarchism or Chomsky's thought.
