Five Ways: St. Thomas Aquinas' Proofs of God's Existence

Philosophers and theologians who still consider belief in God to need rational justification frequently offer the arguments of Aquinas as such as 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. The arguments are evaluated critically to show what they establish and what they fail to establish.
