I was so intrigued by our "Paradox of the Stone" debate that I mentioned it to my dad one night at dinner, and he made an interesting observation. His argument was that no, God cannot possibly make a stone he cannot lift because God controls gravity. In zero gravity, anything is liftable.
This makes sense, given that we agreed in class that God easily has power over biological and physical phenomena. Since gravity is nothing more than physics, it follows that God can manipulate gravity, thus making anything liftable without compromising the integrity of his omnipotence. While I admit this is not the most ground breaking revelation to the argument, it did provide a little extra illumination for me, so I thought I'd share it.
