Having skimmed the posts it seems that the impass that I left on Friday has not disappeared, and there is no reason to believe it would have. I see that the matter of prophecy has entered the discussion, and, to me, this would seem to be a particular problem for the OV.
It appears that the main response to the question of causality is to substitute the concept "free will." Free will is sort of a black box. We are to assume, it would seem, that free will choices are supposed to "just happen." They are not caused by anything, and are, therefore, unpredictable.
Another argument seems to be that at times God intervenes, which changes the causal path, and, again, the future becomes unpredictable.
The matter of causality as it relates to human behavior is extremely complex. Far moreso than we could ever really wrap our arms around. As I have said previously, however, we should not impose our limitations on God. To say that a free will choice is uncaused is simply absurd. I have given several examples along the way that indicate how causal mechanisms impact free will decisions. If decisions and actions are subject to causal processes, then God can foreknow them, there really is no way around that.
As to divine intervention, it seems to me preposterous to argue that God cannot know the outcome of His intervention. Intervention may change the causal path, it no doubt does. But then a new causal sequence emerges, and this sequence, again is not beyond the knowledge of God.
I would appreciate it if any of the OV brethren could address these points without resorting to "free will," which is simply not relevant to the argument. In the alternative, please specify how you think free will choices come about.
