Book excerpt: A new and groundbreaking investigation which takes full account of the finding of the social and historical sciences whilst offering a religious interpretation of the religions as different culturally conditioned responses to a transcendent Divine Reality. Written with great clarity and force, and with a wealth of fresh insights, this major work (based on the author's Gifford Lectures of 1986-7) treats the principal topics in the philosophy of religion and establishes both a basis for religious affirmation today and a framework for the developing world-wide inter-faith dialogue.
