This book confronts the key questions surrounding comparative secularism in historical perspective. The contributions critically consider the normative ideas and alternative political arrangements that govern religion's relation to politics and to the public and private spheres. Containing contributions by world-renowned scholars such as Michael Walzer, Asma Afsaruddin and Sudipta Kaviraj, this book recounts the arguments, debates, and disputations regarding secular arguments for accommodating religion. It does so in both critical and appreciative ways and describes some of the outcomes in actually existing institutions, policies, and practical arrangements. With the addition of many non-Western experiences and viewpoints on how secularism is theorized and lived, politically and historically and from Europe and Asia to Africa and the Americas, this volume is of great value political philosophers across the globe.
