I found this interesting and woundered what others thought about it:
1. God's knowledge cannot be wrong.
2. God knows that I will do A.
3. If I have free will, then (I can do A) and (I can do ~A).
4. If I can do ~A, then it is possibly true that I will do ~A.
5. If it is possibly true that I will do ~A, then God's 'knowledge' that I will do A is possibly false.
6. If God's knowledge that I will do A is possibly false, then God's
'knowledge' can be wrong.
7. Therefore, God's knowledge that I will do A is not possibly false.
8. Therefore, it is not possibly true that I will do ~A.
9. Therefore, I cannot do ~A.
10. Therefore, it is false that (I can do A) and (I can do ~A).
11. Therefore, I don't have free will.
