Coedited by Craig Calhoun, Mark Juergensmeyer, and Jonathan VanAntwerpen, this volume aims to help reframe discussions of religion in the social sciences by drawing attention to the central issue of how “the secular” is constituted and understood, and how new understandings shape both analytic perspectives in the social sciences and various practical projects in politics and international affairs. Contributors include Scott Appleby, Talal Asad, Rajeev Bhargava, Craig Calhoun, José Casanova, Elizabeth Shakman Hurd, Mark Juergensmeyer, Peter Katzenstein, Cecelia Lynch, Richard Madsen, Alfred Stepan, Charles Taylor, and Peter van der Veer.
