The _minimal free will thesis_ (MFT) holds that at least some of the time, someone has more than one course of action that he can perform. ⁽¹⁾ This is the least that must be true in order for it to be said that there is free will. It may be disputed whether the truth of MFT is _sufficient_ for us to 'have free will,' ⁽²⁾ but there is no doubt that the main philosophical challenge to the belief in free will has come from the thesis of universal determinism, so understood as to exclude MFT. A proof of MFT is therefore of considerable philosophical interest, whether or not it constitutes a full proof of free will. In any case, it is the minimal free will thesis of which I have a proof to offer.

Most of us are certain that we have free will, though what exactly this amounts to is much less certain. According to David Hume , the question of the nature of free will is “the most contentious question of metaphysics.” If this is correct, then figuring out what free will is will be no small task indeed. Minimally, to say that an agent has free will is to say that the agent has the capacity to choose his or her course of action. But animals seem to satisfy this criterion, and we typically think that only persons, and not animals, have free will. Let us then understand free will as the capacity unique to persons that allows them to control their actions. It is controversial whether this minimal understanding of what it means to have a free will actually requires an agent to have a specific faculty of will, whether the term "free will" is simply shorthand for other features of persons, and whether there really is such a thing as free will at all.

More particularly, I have been influenced by a conviction that the present state of philosophical opinion on free will is, for certain definitely assignable ...

Free will sceptics claim that we do not possess free will—or at least, that we do not possess nearly as much free will as we think we do. Some free will sceptics hold that the very notion of free will is incoherent, and that no being could possibly possess free will (Strawson this volume). Others allow that the notion of free will is coherent, but hold that features of our cognitive architecture prevent us from possessing free will. My concern in this chapter is with views of the second kind. According to an increasingly influential line of thought, our common-sense commitment to the existence of free will is threatened in unique ways by what we are learning from the sciences of human agency.

In this paper, I respond to Adolf Grünbaum’s charge that the cosmological problem to which the theological doctrine of divine creation would, if true, be a solution is really only a pseudoproblem. My discussion focuses on three questions: Why does the possible world that is in fact actual obtain, rather than any of the other possible worlds? Why does a possible world with the natural laws of the actual world obtain, rather than some possible world with a different nomological structure? And why does a possible world in which some contingent things exist obtain, rather than the possible world in which nothing contingent exists? I argue that each of these questions can be understood in such a way that it avoids Grünbaum’s pseudoproblem charge. I also argue that the second and third questions give rise, if pressed, to problems that science cannot solve. Their ultimate answers are either appeals to inexplicable brute facts, which are not explanatory, or appeals to extrascientific explanations, which could be theological.
