The Five Ways: St. Thomas Aquinas' Proof of God's Existence [Book Review]
Abstract
Some will wonder why this book was ever written, thinking perhaps that there is nothing more to be said about "proofs" for the existence of God. Others of a more traditional inclination might be surprised at some of the conclusions drawn by the author. Kenny carefully scrutinizes the five ways of St. Thomas and concludes that they do not constitute rational proofs for God's existence. Kenny's chief criticism is that the arguments of Aquinas are too closely wedded to a cosmology that cannot stand up under a modern critique. The value of this book rests precisely in its use of contemporary philosophy in evaluating the five ways. Perhaps the author's most serious criticism is directed against the Thomistic concept of esse and the notion of God as ipsum esse subsistens. These metaphysical notions of Aquinas have long been acclaimed as extensions of Aristotelian thought. Kenny, however, claims that they are Platonic in nature and hence subject to the centuries of criticism leveled against Plato's Ideas. Under a logical analysis, the notion of God as ipsum esse subsistens "turns out to be the Platonic Idea of a predicate which is at best uninformative and at worst unintelligible."--J. J. R.
