In this concise introduction, Chad Kautzer demonstrates the shared emancipatory goals and methods of several radical philosophies, from Marxism and feminism to critical race and queer theory.Radical Philosophy examines the relations of theory and practice, knowledge and power, as well as the function of law in creating extralegal forms of domination.Through a critical engagement with the history of philosophy, Kautzer reconstructs important counter-traditions of historical, dialectical, and reflexive forms of critique relevant to contemporary social struggles.The result is an innovative, systematic guide to radical theory and critical resistance.
