During the academic years 2012/13 and 2013/14, the Shelby Cullom Davis Center for Historical Studies will focus on belief and unbelief and how they have interacted in history. How has the line been drawn between religion and other forms of deeply held conviction: secularism, secular religions, political theologies, and the like? At issue are not just questions of demarcation and definition but processes: secularization, proselytizing, conversion. How does belief manifest itself in lived experience, in ritual, observance, and daily-life practices? How have people and cultures moved across the borderline between belief and unbelief? How has belief itself become a subject of study, whether from a secular or theological point of view? As always, we hope to address these questions from a wide variety of periods and places, from prehistory to the present and from all parts of the world.
