The Existence of God: Argument from Eternal Truths

I think that there are certain ideas – like in mathematics and logic – that are necessarily true in a way that is separate from space, time, and material things. Such ideas must exist in a way that is very different from material things. We could suppose that these ideas are products of our minds; and there does seem to be something mental about them. But these ideas also seem to have real effects in the material world. All matter in the universe behaves in consistently mathematical ways that don’t depend on our minds. Still, I think we’re right to understand these ideas as mental. They just have to be features of a very different kind of mind, a mind that is eternal and that has effects on all the matter in the universe.
