Is belief in the Christian God intellectually defensible? Is it even morally necessary? In this book, Dr. Shabbir Akhtar, himself a Muslim, examines and rejects one fideist and two reductionist defences of the rationality of Christian conviction in modern industrial society. He identifies another defensive position—"theological revisionism"—which has recently gained popularity with secularized Christian thinkers. Rejecting this as merely a conservative version of reductionism, he emphasizes the need for reviving the tradition of natural theology and, in doing so, a religious vision of the world.
