Over a career spanning nearly seven decades, Jürgen Habermas - one of the most important European philosophers of the twentieth and twenty-first centuries - has produced a prodigious and influential body of work. In this Lexicon, authored by an international team of scholars, over 200 entries define and explain the key concepts, categories, philosophemes, themes, debates, and names associated with the entire constellation of Habermas's thought. The entries explore the historical, philosophical and social-theoretic roots of these terms and concepts, as well as their intellectual and disciplinary contexts, to build a broad but detailed picture of the development and trajectory of Habermas as a thinker. The volume will be an invaluable resource for students and scholars of Habermas, as well as for other readers in political philosophy, political science, sociology, international relations, cultural studies, and law.

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
