Dr. Robert McCauley is the William Rand Kenan Jr. Professor and the Director of the Center for Mind, Brain, and Culture at Emory University. Considered to be one of the founders of the Cognitive Science of Religion, his research interests in this area have centered on the cognitive foundations of religion and religious ritual. His work (often in collaboration with another founder of the field, E. Thomas Lawson) has provided many insights into the evolved cognitive mechanisms that underpin religious thought. Dr. McCauley joins us to discuss his lively and fascinating new book, Why Religion is Natural and Science is Not.
