This book offers a lively debate concerning the nature of morality and its foundations by a wide variety of contributors from both religious and nonreligious perspectives. The international list of contributors are all well-known and seasoned debaters. They include neuroscientists, analytic philosophers, theologians, Christian apologists, philosophers of science, mathematicians, bioethicists, and a theoretical physicist and Nobel laureate. Rarely do the perspectives represented by this high-caliber slate of contributors find their way into a single volume. The spirited debate offered in these pages deserves a wide hearing. -- Philip Blosser, Sacred Heart Major Seminary
