This is the first book to consider the debate between two of the most prominent philosophers and social theorists of the 20th century: Jacques Derrida and J?rgen Habermas. It presents a unique collection of articles by the two figures and by those who have written about them, and includes pieces published in English for the first time. The book will be of interest to students and scholars with an interest in the implications of Derrida' deconstruction and Habermas's critical theory for issues such as international relations, Europe, tolerance, rights, multiculturalism and identity politics, and the nature of philosophy. Including an introduction to the differences and affinities between Derrida's and Habermas's works, introductions to each text, suggestions for further reading, and a bibliography, this book is the ideal starting point for students and scholars wishing to understand the relationship between these two great thinkers, Lasse Thomassen is a Junior Lecturer in the Department of Politics and Public Administration at the University of Limerick. He is co- editor of Radical Democracy: Politics Between Abundance and Lack (2005)
