This book explores the value impact that theist and other worldviews have on our world and its inhabitants. Providing an extended defense of anti-theism - the view that God existence would (or does) actually make the world worse in certain respects - Lougheed explores God impact on a broad range of concepts including privacy, understanding, dignity, and sacrifice. The second half of the book is dedicated to the expansion of the current debate beyond monotheism and naturalism, providing an analysis of the axiological status of other worldviews such as pantheism, ultimism, and Buddhism.   A lucid exploration of contemporary and relevant questions about the value impact of God existence, this book is an invaluable resource for scholars interested in axiological questions in the philosophy of religion.
