The five ways: Saint Thomas Aquinas' proofs of God's existence (Studies in ethics and the philosophy of religion)

Philosophers and theologians who still consider belief in God to need rational justification frequently offer the arguments of Aquinas as such a justification. This book is a systematic study of the Five Ways by which St. Thomas Aquinas, in the Summa Theologiae, said that the existence of God could be demonstrated. Dr. Kenny seeks to establish what St. Thomas meant by the steps in these proofs, and he looks for illumination in parallel passages elsewhere in the works. The arguments are evaluated critically to show what they establish and what they fail to establish.
