Earlier today on Cameron Bertuzzi’s Capturing Christianity program, I had a very pleasant and fruitful live exchange with Graham Oppy. You can watch it on YouTube. This is the second exchange Oppy and I have had on the show. The first was last July, and you can still watch that on YouTube as well. In that earlier exchange we discussed my book Five Proofs of the Existence of God. The book comes up in the latest exchange as well, as does Oppy’s Religious Studies article “On stage one of Feser’s ‘Aristotelian proof.’”
