Rainer Forst’s Toleration in Conflict (published in English 2013) is the most important historical and philosophical analysis of toleration of the past several decades. Reconstructing the entire history of the concept, it provides a forceful account of the tensions and dilemmas that pervade the discourse of toleration. In his lead essay for this volume, Forst revisits his work on toleration and situates it in relation to both the concept of political liberty and his wider project of a critical theory of justification. Interlocutors Teresa M. Bejan, John Horton, Chandran Kukathas, Daniel Weinstock, Melissa S. Williams, Patchen Markell and David Owen then critically examine Forst’s reconstruction of toleration, his account of political liberty and the form of critical theory that he articulates in his work on such political concepts. The volume concludes with Forst’s reply to his critics.
