What is God?  What does it mean to believe in God?  What happens to God after the death of God? This book examines “the death of God� from a philosophical standpoint. It focuses on monotheism, polytheism, and nature, and it discusses the renewed importance of spirituality—and the “spiritual but not religious�—in response to the death of God. In recent years, religious belief has been in decline, but secularism cannot satisfy our spiritual needs.  We are now living in a “post-secular� age in which the relationship between philosophy, spirituality, and religion must be re-examined. As an exploratory essay, this book engages the reader at a profound level, and considers a variety of modern thinkers, including Nietzsche, Hegel, Freud, Levinas, Assmann, and Buber.  It offers a sustained meditation on the origin of God, the death of God, and the future of “God� as a guiding ideal.
