"It is at once a virtue and challenge of this book that we are presented with meticulous reconstructions of historical forms of the argument, together with variations and objections (and often objections to the objections) that are both amazing and intimidating in their thoroughness....In addition to the main text, the book contains an appendix of some 130 pages, in which O. surveys virtually every significant discussion of the various forms of the ontological argument in the recent literature." Theological Studies

This book is a unique contribution to the philosophy of religion. It offers a comprehensive discussion of one of the most famous arguments for the existence of God: the ontological argument. The author provides and analyses a critical taxonomy of those versions of the argument that have been advanced in recent philosophical literature, as well as of those historically important versions found in the work of St. Anselm, Descartes,Leibniz, Hegel and others.
