It seems to me that some folks--perhaps not philosophers--think that Open Theism (OT) somehow significantly helps with the Problem of Evil. But I do not think it does. The natural reason to think OT helps is to say that if an omnipotent God foreknows that George will freely do some evil E, then God can prevent George from doing E, and OT means that God can't foreknow it, so we can't blame God for failing to prevent E. But this is confused. For it would be impossible for God to both foreknow--or even forebelieve--E and prevent E. Foreknowledge does let God put plans for an event into effect before the event happens, but for actual prevention of foreknown evils, what would be needed is Middle Knowledge, not foreknowledge.
I am curious if any philosophers have committed the error I criticize here.
