Christian theism has traditionally claimed that God knows the future. But why is divine foreknowledge important? In this essay, I argue that divine foreknowledge is valuable to Christian theism and that a hefty theological price must be paid if it is rejected. I also attempt to show that the range of knowledge available to God in theological models that deny divine foreknowledge is significantly less than claimed by proponents of these views. In particular, I argue that the God of such models could not know future physical necessities, physical probabilities, divinely intended future free acts, or future events required by the divine nature.

Two major objections to divine atemporality center on supposed tensions between the claim that God is omniscient and the claim that he is timeless. Since most defenders of divine timelessness are even more firmly committed to omniscience, driving a wedge between the two is intended to convert such persons to a temporal view of God. However, I believe that both arguments fail to demonstrate an incompatibility between omniscience and timelessness, and that the objections themselves rest in large part on misunderstandings regarding both the motivation for and substance of the doctrine of divine timelessness.

David Hunt has recently developed a new strategy, called the “dispositional omniscience scenario,” or (OOS), which is designed to defeat theological fatalism by showing the compatibility of divine foreknowledge and human (libertarian) free agency. But I argue that Hunt fails to establish his compatibility claim because (DOS) is based on a defective analysis of dispositional belief that is too weak to sustain any divine foreknowledge of future free actions.

I argue that the simple foreknowledge view, according to which God knows at some time t 1 what an agent S will do at t 2 , is incompatible with human free will. I criticize two arguments in favor of the thesis that the simple foreknowledge view is consistent with human freedom, and conclude that, even if divine foreknowledge does not causally compel human action, foreknowledge is nevertheless relevantly similar to other cases in which human freedom is undermined. These cases include those in which certain human actions are logically, rather than causally, foreclosed.

Suppose it were known, by someone else, what you are going to choose to do tomorrow. Wouldn't that entail that tomorrow you must do what it was known in advance that you would do? In spite of your deliberating and planning, in the end, all is futile: you must choose exactly as it was earlier known that you would. The supposed exercise of your free will is ultimately an illusion. Historically, the tension between foreknowledge and the exercise of free will was addressed in a religious context. According to orthodox views in the West, God was claimed to be omniscient (and hence in possession of perfect foreknowledge) and yet God was supposed to have given humankind free will. Attempts to solve the apparent contradiction often involved attributing to God special properties, e.g. being 'outside' of time. However, the trouble with such solutions is that they are generally unsatisfactory on their own terms. Even more serious is the fact that they leave untouched the problem posed not by God's foreknowledge but that of any human being. Do human beings have foreknowledge? Certainly, of at least some events and behaviors. Thus we have a secular counterpart of the original problem. A human being's foreknowledge, exactly as would God's, of another's choices would seem to preclude the exercise of human free will. Various ways of trying to solve the problem – e.g. by putting constraints on the truth-conditions for statements, or by 'tightening' the conditions necessary for knowledge – are examined and shown not to work. Ultimately the alleged incompatibility of foreknowledge and free will is shown to rest on a subtle logical error. When the error, a modal fallacy, is recognized, and remedied, the problem evaporates.

In this paper, I consider Augustine’s attempted solution of the problem of divine foreknowledge and free will. I focus on two distinct notions of God’s relationship to time as they relate to this problem. In Confessions XI, Augustine develops an understanding of time and foreknowledge that cIearly offers a possible solution to the foreknowledge/free will problem. I then turn to On Free Will 3 .1-4, where Augustine conspicuously declines to use a solution similar to the one in the Confessions, rather developing a response that demands a very different conception of foreknowledge. I subsequently argue that in On Free Will, Augustine’s argument requires that God’s foreknowledge, when considered in light of events involving human freedom, must be in a real sense dependent on the results of free choice.
