The possibility of proving the existence of God has fascinated thinkers and believers throughout the centuries. For those like Richard Swinburne, such a project is both worthwhile and successful. For others, like D. Z. Phillips, it is wholly inappropriate. Most critics have simply taken sides at this point; but this book argues a way forward, showing that the disparity between Swinburne and Phillips goes deeper - questioning the fundamental nature of God, the meaning of religious language, and the proper task of philosophy. The author argues that behind each thinker's work, and their attitudes towards proving the existence of God, lies fundamental trust. A positive discussion of relativism leads to a fresh analysis of the arguments for God's existence, particularly the ontological argument: Dr Messer shows that these are worthwhile - although not for the traditional reasons.
