Can a neuroscientist help a theologian interpret a medieval mystical text? Can a historian of religion help an anthropologist understand the effects of social cooperation on human evolution? Can a legal scholar and a theologian help each other think about how fear of God relates to respect for the law? In this volume leading scholars in ethics, theology, and social science sum up three years of study and conversation regarding the value of interdisciplinary theological inquiry. This is an essential and challenging collection for all who set out to think, write, teach, and preach theologically in the contemporary world.
