On the occasion of Habermass 80th birthday, the German publisher Suhrkamp brought out five volumes of Habermass papers that spanned the full range of his philosophical thought, from the theory of rationality to the critique of metaphysics. For each of these volumes, Habermas wrote an introduction that crystallized, in a remarkably clear and succinct way, his thinking on the key philosophical issues that have preoccupied him throughout his long career. This new book by Polity brings together these five introductions and publishes them in translation for the first time. The resulting volume provides a unique and comprehensive overview of Habermass philosophy in his own words.In the five chapters that make up this volume, Habermas discusses the concept of communicative action and the grounding of the social sciences in the theory of language; the relationship between rationality and the theory of language; discourse ethics; political theory and problems of democracy and legitimacy; and the critique of reason and the challenge posed by religion in a secular age. The volume includes a substantial introduction by Jean-Marc Durand-Gasselin, which offers a synoptic view of the development of Habermass thought as a whole followed by concise accounts of his contributions in each of the areas mentioned. Together they provide the reader with the necessary background to understand Habermass distinctive and original contribution to philosophy.Philosophical Introductions will be an indispensable text for students and scholars in philosophy and in the humanities and social sciences generally, as well as anyone interested in the most important developments in philosophy and critical theory today.

Jürgen Habermas is Emeritus Professor of Philosophy at the Johann Wolfgang Goethe University of Frankfurt and one of the most influential social and political thinkers in the world today.
