A God Equation

Well, the traditional answer (and in my view the correct one) to the paradox of God and the rock is that the omnipotence of God means that he can bring about any state of affairs not that he can make any sentence true. For example, according to the old joke, even God himself cannot make "two hills without a valley between them" --- if they had no valley between them, they'd be one hill. But this is not really a limit on his omnipotence, because the phrase "two hills without a valley between them" does not describe even a conceivable state of affairs.

Quite so, he's meant to be omnipotent. But I didn't say there were things he couldn't do: rather, there are sentences which, being meaningless, would never describe anything that he did.
