 Ever since the dilemma of this article was identified, there have been philosophers who thought that something like our basic argument succeeds in demonstrating that infallible foreknowledge is incompatible with human free will. If they are incompatible, one of them must be given up. It’s possible to give up both, of course, but that’s more than the argument requires, and one reason the dilemma has attracted so much attention in the history of philosophy is that both the belief in a being with infallible foreknowledge and belief in the existence of libertarian free will are strongly entrenched in the world view of many philosophers. To give up either of these beliefs is difficult and often has many ramifications for one’s other beliefs.
