Why I'm a compatibilist about free will I'm not talking about omniscience at all, just a being with a rewind button for our universe. If a brain in a vat dragon has the rewind button, then he's the god in question.
The difference between indeterminism and determinism is, given the exact same conditions, with determinism you get the exact same result every time. With indeterminism you don't. That's what this rewind test is all about. It's an easy to visualise way of setting up the same exact conditions.
So when you say "could in fact choose", I'm trying to figure out if you mean like in an indeterministic way, or if you mean some other way.
Because some people think you "could in fact choose" even if you get the same result every time from the same condition.
