Jürgen Habermas is one of the greatest philosophers, sociologists and political theorists in the world today. His polymathic brilliance and intellectual range has allowed him to construct a formidable social and political framework influenced by traditions ranging from Kantian ethics and American pragmatism to Marxism and the German philosophical heritage. Perhaps most famous for his theory of the rise of the public sphere as a forum for rational public debate in the late eighteenth century, his contributions to our understanding of democracy, civil society, the modernization process and religion are incalculable. In addition, he has become an insightful commentator on contemporary politics, proving to be one of the most important analysts of the promises and the shortcomings of the European project. Polity has published nearly 30 books by Habermas, including The Structural Transformation of the Public Sphere, The Theory of Communicative Action, The Philosophical Discourse of Modernity and Philosophical Introductions: Five Approaches to Communicative Reason.
