This intensive seminar will discuss St. Thomas Aquinas’s Five Ways of proving the existence of a God and the conception that he thinks they yield: that of a God who is at once utterly simple and utterly perfect, and therefore utterly beyond our comprehension. The sessions will center on Summa Theologiae, I, qq. 2-4—especially, of course, q. 2, a. 3, which contains the Five Ways themselves—and on selected texts from qq. 12 & 13. Participants will also discuss relevant passages from other works of St. Thomas, as well as his historical influences and some related contemporary issues.
