In this episode, we interview Willemien Otten, Professor of Theology and the History of Christianity at the University of Chicago and Director of the Martin Marty Center for the Public Understanding of Religion. The discussion focuses on Professor Otten's new book, Thinking Nature and the Nature of Thinking: From Eriugena to Emerson (Stanford University Press, 2020). The conversation ranges from cosmology, history, and medieval theology to ecumenism and the contemporary environmental crisis. Professor Otten makes the case for a new natural theology relevant for the 21st century.
