Comparative Secularisms in a Global Age explores the history and politics of secularism and the public role of religion in France, India, Turkey, and the United States. It interprets the varieties of secularism as a series of evolving and contested processes of defining and remaking religion, rather than a static solution to the challenges posed by religious and political difference. It features essays from leading scholars from across disciplines, secular and religious traditions, and regional expertise. The volume illustrates a new approach to the hotly contested relation between political authority and religious tradition.
