Jesus' Mission....

[GrandizerII]

You could have done not-X. In other possible worlds, that's what you do. But God actualizes the world in which you do X.

So in this sense, God knows beforehand what you would do in this actual world because he knows what world he actualized, but this doesn't mean you weren't free to have done not-X (because in other possible worlds, you do just that).

I agree, though, free will perse (in the libertarian sense) makes no sense, but we're assuming that somehow free will is possible.

I'm not sure that 'other possible worlds' applies here.  Even if it does, the argument doesn't change, as God will have actualized those worlds as well, and he would have actualized them in such a way that I will either do X or not-X.  God has predetermined what I will do or not do.  There not only is not choice, there is no possibility of choice.

Possible worlds don't necessarily mean they must be actualized.

And what I'm trying to say is that God predetermines what world is actual in light of which free choice you make God predetermines to be actual. It's a matter of adjusting your perspective to see it differently from how you're currently seeing it.

But again, this assumes that somehow free will can somehow make sense in terms of modal logic. I don't think it does, but that's why I'd rather just say free will makes no sense rather than make it more difficult for myself by arguing for incompatibility between God's omniscience and this free will thing that's supposed to make sense but doesn't.

Possible worlds semantics only reasserts the dilemma.  If it's necessarily true in one possible world that you must choose the snickers, then it's true in all possible worlds that you must choose the snickers.

It should be contingently, though.

If it's contingently true in one possible world that you choose the snickers, then it's true that in other possible worlds you do not.
