 Consider the mental state God is in when he knows that Tom freely files his tax return on April 14th, 2014. This divine mental state is an intrinsic state God is in contingently. If God were identical to this state, then he could not be a se. For if God were identical to the state, then God would be dependent on something – Tom’s libertarianly free action – that is external to God and beyond his control. Now anything that compromises the divine aseity will compromise the divine simplicity, the latter being an entailment of the former. So it seems that an omniscient God cannot be simple if there are free creaturely agents and God knows what they do and leave undone. There is also the problem that if the divine mental state in question were identical to God, then the truth God knows when he knows that Tom files on April 14th would be necessarily true.
