'What, exactly, is liberal about passing restrictive policies designed to defend liberalism from the claims of religious populations? Nothing, is the answer given in this challenging and provocative book. In fact, many of the authors of these essays contend that European states have responded to the rise of Islam in their midst with a peculiar form of cultural and political sectarianism that has, at times, been glaringly illiberal. This book is sure to shape debate on a classic theoretical question that now resides at the heart of contemporary European politics.' Tim Byrnes, Colgate University
