Hosts Celeste Carey and Cecil Prescod interview religious scholar and philosopher Jacob Needleman about his new book, "What Is God?" In the book Needleman traces his evolution from an atheistic Ivy-educated student of philosophy to a Zen Buddhist seeker, and finally to a believer with a newfound respect for the religious texts he once rejected. Jacob Needleman, author of "The American Soul" and "Money and the Meaning of Life," is Professor of Philosophy at San Francisco State University.
