Divine Foreknowledge and Fatalism
Nathan Rockwood attempts to address the difficulties of divine foreknowledge in his paper “Foreknowledge without Determinism.” I will outline the argument he addresses, which premise he objects to, and the problem with his objection.
-
If God is omniscient, he cannot be wrong about what human agents will do in the future.
-
God is omniscient.
-
So, God cannot be wrong about what human agents will do in the future. (MP 2,1)
-
If God cannot be wrong about what human agents will do in the future, then human agents cannot do otherwise.
-
So, human agents cannot do otherwise. (MP 3,4)
-
If free will exists, then human agents can do otherwise.
-
Therefore, free will does not exist. (MT 5,6)
Rockwood objects to (1). He argues that, in principle, God can be wrong about what human agents will do in the future while retaining his essential trait of omniscience. He says that, in practice, God simply is never wrong about the future, even though he could be. This is a modal argument where God is never wrong in this world, although there are possible worlds where he is wrong. This strikes me as false. A perfect and omniscient God necessarily exists in all possible worlds. Not only does he exist in every one of these worlds, but his essential characteristics must be retained in all possible worlds. Therefore, if God exists, there can be no possible world where he is wrong about the future. Rockwood claims that there is a possible world where he is wrong about the future, and so you would be forced to conclude that, therefore, God does not exist.
