The famed pro-life philosopher Francis Beckwith is in my department. Knowing that he dwells on deep questions from time to time, I asked him one presented by my sister-in-law. She wondered, "If God is omnipresent, is God in Hell?" This is the sort of question to make the scholastics dance (on the head of a pin, perhaps). When I heard it, I shrugged it away as one of those many mysteries that characterize the faith. After all, how could I know?
Nevertheless, I saw good Beckwith walking the hall and asked him. He responded instantly that God is not in Hell. Why? He explained that though God is the necessary condition for everything that exists, He does not actually take up physical space. Thus, he does not, of necessity, have to occupy space in Hell. He then started to talk about whether one would need to go to church again if one crossed the international date line on Sunday. We'll save that for another time.
Beckwith occasionally browses this blog, so perhaps he'll write in if I (due to lack of philosophical training) have failed to adequately explain his argument.
