The possibility of proving the existence of God has fascinated thinkers and believers throughout the centuries. This book critically analyzes both sides of the contemporary debate between the two most important living philosophers of religion--Richard Swinburne and D.Z. Phillips--and constructs an alternative solution. Instead of taking sides on the issue of God's existence, Messer argues that behind each thinkers' work, and their attitudes toward 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. In this way, Messer concludes that they are indeed worthwhile, although not for the traditional reasons.
