Book excerpt: This book challenges the modern myth that tolerance grows as societies become less religious. The myth inseparably links the progress of toleration to the secularization of modern society. This volume scrutinizes this grand narrative theoretically and empirically, and proposes alternative accounts of the varied relationships between diverse interpretations of religion and secularity and multiple secularizations, desecularizations, and forms of toleration. The authors show how both secular and religious orthodoxies inform toleration and persecution, and how secularizations and desecularizations engender repressive or pluralistic regimes. Ultimately, the book offers an agency-focused perspective which links the variation in toleration and persecution to the actors of secularization and desecularization and their cultural programs.
