Read moreThe cause of an event must continue over a period at which the effect is not occurring and the whole period at which it is occurring. It follows that simultaneous causation and backward causation are metaphysically impossible. I distinguish among events said to occur at a time, ‘hard’ events which really occur solely at that time and ‘soft’ events which occur partly at another time. God’s beliefs at a time are hard events at that time. It follows that if God is a temporal being, he cannot know infallibly what either we or he will do freely at a future time; and if God is timeless, he cannot know what happens in time. Hence we must define God’s ‘omniscience’ in such a way as to exclude any knowledge of future free actions. I discuss in an Appendix how far this view is compatible with Scripture and Church tradition.
