This essay explores the philosophical significance of the history of mystical anarchism for contemporary ethics and politics. It examines the complex relationship between religion and politics, and elaborates the thesis that many of our contemporary political concepts are secularized theological concepts. After a critical discussion of Carl Schmitt's theory of sovereignty and John Gray's critique of liberal humanism, it examines the anarchist practices of medieval mystics such as Marguerite Porete and the heresy of the Movement of the Free Spirit, and (...) contrasts this mystical anarchist tradition with more recent forms of anarchism, such as Raoul Vaneigem's Situationism.Retrieving the mystical anarchist tradition might help us rethink the relationship between religion and politics and suggest ethically grounded forms of anarchism that avoid violence or abstraction.
