The Twentieth Annual Westar Religious Literacy Seminar in Sarasota

Over the course of the seventeenth through nineteenth centuries, the term God effectively stopped working as an explanation for the origins of things, the history of languages and the nature of the cosmos. By the twentieth century, it became clear that the concept of God no longer made sense, that God is (so to speak) dead. Presenters David Galston and Jack Kelly will ask if there is any value to religion after the death of God. Or whether it is possible that religion without God might compose the best option for the future.
