The philosophy of religion is a growing and flourishing field, as may be seen from the increasing numbers of textbooks, anthologies, and companions now available in the area. This book certainly does not try to cover all the topics that have been included under the heading ‘philosophy of religion’, though it aims to discuss those I take to be the most central. It is primarily a work of philosophy, as opposed to philosophical theology, and does not include detailed discussion of doctrines like the Trinity or the Incarnation that have received attention from philosophers (often very fruitfully and interestingly) in recent years. Nor, apart from one or two brief passing references, does it venture into comparative world religion, which has become a vast and fascinating academic field in its own right. All philosophizing (whether its practitioners acknowledge it or not) is inevitably conducted within a given cultural and historical context, and this book is no exception, being primarily informed by the philosophical tradition going back to Plato and Aristotle, and the religious tradition whose roots go back to the Judaeo-Christian scriptures. The audience at which the book is aimed includes colleagues and students working in the philosophy of religion, but I have tried to make the philosophy accessible to as wide a readership as possible. Many of the topics are inevitably complex, but I have endeavoured to avoid technical jargon, and for the most part I have avoided engaging with the minutiae of the debates in the recent academic literature.
