'pre-observable'. You are saying that if the outcome of a choice can be observed 'before' it happens, then it can't be a choice. Sounds fair enough to me. But that principle cannot be applied to the hypothetical situation of a god and it's creation. God can't observe anything 'before' it's happened. The past, future and present all happen at once. Even that statement doesn't fully capture the situation. It all comes down to Time. The same idea could be applied to a person reading a book or watching a film, which run along different a time. Still, it could possibly be argued that free choice still holds even if the outcome is pre-observed within the same timeframe. If there's one thing modern physics has taught us about Time, it's that the arrow of time doesn't point in one direction only. The future effects the past, just as much as the past effects the future. Why does it matter if I 'pre-observe' someone's choice? If they had made a different choice, I would simply have 'pre-observed' something else. There is nothing that says my observation cancels out their freedom. If I had a pair of 'future' binoculars, and I see someone turn left, I can't see why that automatically means it was physically impossible for them to turn right, or that they had no choice in the matter.
