All in Divine Foreknowledge
We typically think we have free will. But how could we have free will, if for anything we do, it was already true in the distant past that we would do that thing? Or how could we have free will, if God already knows in advance all the details of our lives? Such issues raise the specter of "fatalism".
This Introduction has three sections, on "logical fatalism," "theological fatalism," and the problem of future contingents, respectively. In the first two sections, we focus on the crucial idea of "dependence" and the role it plays it fatalistic arguments.
Theological fatalists contend that if God knows everything, then no human action is free, and that since God does know everything, no human action is free. One reply to such arguments that has become popular recently— a way favored by William Hasker and Peter van Inwagen—agrees that if God knows everything, no human action is free.
In contemporary philosophy, arguments for “fatalism” are arguments for the conclusion that no human actions are free. Such arguments typically come in two varieties: logical and theological.
The most promising way of responding to arguments for the incompatibility of divine foreknowledge and human freedom (in one way or another) invokes a claim about the order of explanation: God knew (or believed) that you would perform a given action because you would, in fact, perform it, and not the other way around.
In the literature on free will, fatalism, and determinism, a distinction is commonly made between temporally intrinsic (‘hard’) and temporally relational (‘soft’) facts at times; determinism, for instance, is the thesis that the temporally intrinsic state of the world at some given past time, together with the laws, entails a unique future (relative to that time).
The plane was going to crash, but it didn't. Johnny was going to bleed to death, but he didn't. Geach sees here a changing future. In this paper, I develop Geach's primary argument for the (almost universally rejected) thesis that the future is mutable (an argument from the nature of prevention), respond to the most serious objections such a view faces, and consider how Geach's view bears on traditional debates concerning divine foreknowledge and human freedom.
In his recent essay in the Philosophical Review, “Truth and Freedom,” Trenton Merricks contends (among other things) that the basic argument for the incompatibility of God's foreknowledge and human freedom is question-begging.
