On a recent broadcast of the Infidel Guy (Sep. 16, 2008), a caller challenged Gary Habermas, the evening's guest, to reconcile the omniscience of God with human free will. Habermas did his best to argue that there is no necessary conflict, that God knows because we freely choose, we do not so choose because God knows. For my part, I think it's a legitimate and difficult objection. I'm not yet persuaded by either Molinist or Openness attempts to reconcile the two, much less compatabilism or the notion that it is solved by God's being outside of time. But what followed is what struck me. Habermas took the opportunity to ask Reggie Finley, the host, whether he, as a naturalist, believed in free will. Reggie paused, then conceded that he was still trying to figure that one out. Good luck, Reggie, because while free will may be problematic for the theist, it is probably a lost cause for the naturalist. For example, in his excellent and lucid work, The Significance of Free Will, Robert Kane manages to find a place for indeterminacy in matter (in quantum theory), but not for agency, the sine qua non of free will in my judgment. My point is not to wade into the deep waters of human freedom. Rather, I'm taking exception to the widespread impression that it is only the theist who must accept mysteries, antinomies, and quandaries. The truth is, all worldviews are beset by unique difficulties and internal conceptual problems. And, we remain perplexed by many mysteries that we share in common. That is to say, we're in this together. With our amazing, but limited human faculties, the world remains puzzling to us all. In the ongoing debate about what is and is not real, it would serve us well to be mindful of the problems with which each worldview must wrestle. To that end, here are some that occur to me for both Christian theism and for Naturalism.
