In Part I, I present two traditional arguments for the incompatibility of divine foreknowledge with human freedom; the first of these is clearly fallacious; but the second, the argument from the necessity of the past, is much stronger. In the second section I explain and partly endorse Ockham’s response to the second argument: that only propositions strictly about the past are accidentally necessary, and past propositions about God’s knowledge of the future are not strictly about the past. In the third (...) part I point out some startling implications of Ockham’s way out; and finally in part IV I offer an account of accidental necessity according to which propositions about the past are accidentally necessary if and only if they are strictly about the past.

"This is an important book, and no one interested in issues which touch on the free will will want to ignore it."--Ethics. In this stimulating and thought-provoking book, the author defends the thesis that free will is incompatible with determinism. He disputes the view that determinism is necessary for moral responsbility. Finding no good reason for accepting determinism, but believing moral responsiblity to be indubitable, he concludes that determinism should be rejected.

This paper has two parts. In the first part, I concede an error in an argument I have given for the incompatibility of free will and determinism. I go on to show how to modify my argument so as to avoid this error, and conclude that the thesis that free will and determinism are compatible continues to be—to say the least—implausible. But if free will is incompatible with determinism, we are faced with a mystery, for free will undeniably exists, and (...) it also seems to be incompatible with indeterminism. In the second part of this paper, I will defend the conclusion that the concept of agent causation is of no use to the philosopher who wants to maintain that free will and indeterminism are compatible. I conclude that free will remains a mystery---that is, that free will undeniably exists and that there is a strong and unanswered prima facie case for its impossibility. (shrink)

Ted A. Warfield has recently employed modal logic to argue that compatibilism in the free-will/determinism debate entails the rejection of intuitively valid inferences. I show that Warfield's argument fails. A parallel argument leads to the false conclusion that the mere possibility of determinism, together with the necessary existence of any contingent propositions, entails the rejection of intuitively valid inferences. The error in both arguments involves a crucial equivocation, which can be revealed by replacing modal operators with explicit quantifiers over possible (...) worlds. I conclude that the modal-logical apparatus used by Warfield obscures rather than clarifies, and distracts from the real philosophical issues involved in the metaphysical debate. These issues cannot be settled by logic alone. (shrink)

I insist that I was able to raise my hand, and I acknowledge that a law would have been broken had I done so, but I deny that I am therefore able to break a law. To uphold my instance of soft determinism, I need not claim any incredible powers. To uphold the compatibilism that I actually believe, I need not claim that such powers are even possible. My incompatibilist opponent is a creature of fiction, but he has his prototypes (...) in real life. He is modeled partly after Peter van Inwagen and partly on myself when I first worried about van Inwagen's argument against compatibilism. (shrink)

Joseph Keim Campbell has recently criticized Peter van Inwagen's Third Argument against compatibilism for its reliance on the existence of a remote past. In response, Anthony Brueckner has offered a new version of the Third Argument showing that determinism and free will are incompatible for all times t relative to which there is a past . In this paper I argue that although Brueckner's retooled argument fails to prove anything in favour of incompatibilism, its conclusion can be exploited to provide (...) another version of van Inwagen's original argument that doesn't rely on the existence of past times, thus withstanding Campbell's criticism.

In this essay I present what is, I contend, the free-will problem properly thought through, or at least presented in a form in which it is possible to think about it without being constantly led astray by bad terminology and confused ideas. Bad terminology and confused ideas are not uncommon in current discussions of the problem. The worst such pieces of terminology are "libertarian free will" and "compatibilist free will." The essay consists partly of a defense of the thesis that (...) the use of these phrases by writers on the problem of free will can only generate conceptual confusion and partly of a formulation of the problem that does not make use of them. I contend that this formulation is neutral with respect to the historically important positions on free will (e. g., compatibilism and incompatibilism). (shrink)

There is a new objection to the Consequence Argument for incompatibilism. I argue that the objection is more wide-ranging than originally thought. In particular: if it tells against the Consequence Argument, it tells against other arguments for incompatibilism too. I survey a few ways of dealing with this objection and show the costs of each. I then present an argument for incompatibilism that is immune to the objection and that enjoys other advantages.

The past 25 years have witnessed a vigorous discussion of an argument directed against the compatibilist approach to free will and responsibility. This reasoning, variously called the “consequence argument,” the “incompatibility argument,” and the “unavoidability argument,” may be expressed informally as follows: If determinism is true then whatever happens is a consequence of past events and laws over which we have no control and which we are unable to prevent. But whatever is a consequence of what’s beyond our control is (...) not itself under our control. Therefore, if determinism is true then nothing that happens is under our control, including our own actions and thoughts. Instead, everything we do and think, everything that happens to us and within us, is akin to the vibration of a piano string upon being struck, with the past as pianist, and could not be otherwise than it is. While a number of philosophers take this reasoning to crush the prospects of compatibilism, others challenge its assumption that unavoidability “transfers” from sufficient condition to necessary condition or from cause to effect. The ensuing debate has occasionally been vitriolic— Hume once remarked that the free will issue is “the most contentious question of metaphysics, the most contentious science”—yet undeniably fruitful in generating more detailed examinations of ability and practical freedom. Whether we incline towards compatibilism or 2 incompatibilism, this latter development is likely to be of lasting value. As a compatibilist, I believe that the consequence argument fails to prove incompatibilism, and here I will develop criticisms of it that, for the most part, are already in the existing literature. Although a short essay cannot provide the theoretical account of practical freedom needed to underpin and justify this compatibilist critique, it will clarify the tasks that lie ahead. (shrink)

Essays discuss reason, self-control, self-definition, time, cause and effect, accidents, and responsibility, and explain why people want free will.

Many critics of libertarian freedom have charged that freedom is incompatible with indeterminism. We show that the strongest argument that has been provided for this claim is invalid. The invalidity of the argument in question, however, implies the invalidity of the standard Consequence argument for the incompatibility of freedom and determinism. We show how to repair the Consequence argument and argue that no similar improvement will revive the worry about the compatibility of indeterminism and freedom.

This paper attempts to construct a systematic and plausible account of the necessity of the past. The account proposed is meant to explicate the central ockhamistic thesis of the primacy of the pure present and to vindicate Ockham's own non-Aristotelian response to the challenge of logical determinism.
