Or more specifically; do Calvinists believe that true subjunctive conditionals (or true counterfactuals) exist and have actual truth value?
I just watched
this video by James White in which he takes issue with the idea. The problem is that I've seen other videos of White in which he seems to say that he does believe in the existence of counterfactual information; so I'm not sure if he's just being inconsistent or if I've misunderstood him. But in this video he seems to argue (without explicitly saying so) that true counterfactuals simply cannot exist.
Notice how he argues based on the myriad of possible circumstances humans could have been placed in by God that it would be impossible to know how any of us would have acted if we had been placed in different circumstances. That seems to me to be, in principle, not far removed from an open theist position. An open theist would say that God
cannot exhaustively know the future as settled because of things like free will and the nature of reality. White is saying that God
cannot know anything other than what He has decreed. To White, the existence of true counterfactual information would imply that things exist independently of God. At least that's how I interpret his argument.
I have more thoughts on this but I'll wait and see what others say. I actually am not totally persuaded by Molinism (I think open theism is closer to the truth than Molinism), but I think White's attempts to rebut WLC's argument are quite problematic for his own views.
How can anyone have a problem in principle with open theism if they themselves don't believe that God is capable of knowing something other than what He has decreed to happen?
