The ontological argument has a storied history in philosophy. Formulated by St. Anselm of Canterbury in the eleventh century it holds in its simplest form that the perfection of God entails his existence. This collection includes the original statement of the position by St. Anselm with critiques and commentaries by subsequent philosophers from Aquinas and Descartes to Norman Malcolm. Edited by the noted philosopher Alvin Plantinga, the book includes an informative introductory essay by Richard Taylor. ( )
