Jürgen Habermas's work has profoundly influenced a wide range of fields, including philosophy, political theory, sociology, law, and cultural and communications studies. The Lexicon provides a state of the art, accessible, and comprehensive guide to the key concepts, figures, and debates associated with the entire development of Habermas's work.Advance praise: 'A recent biography referred to Habermas as the most famous living philosopher in the world. But he is also one of the most poorly comprehended. That makes the appearance of this volume a real occasion for enthusiasm. Allen and Mendieta have assembled a remarkably strong group of scholars who provide the reader with a reliable guide to Habermas' central concepts and intellectual trajectory. This is a real gem of scholarship.' Stephen K. White, University of Virginia
