Determinism is a claim about the laws of nature: very roughly, it is the claim that everything that happens is determined by antecedent conditions together with the natural laws. Incompatibilism is a philosophical thesis about the relevance of determinism to free will: that the truth of determinism rules out the existence of free will. The incompatibilist believes that if determinism turned out to be true, it would also be true that we don't have, and have never had, free will. The (...) compatibilist denies that determinism has the consequences the incompatibilist thinks it has. According to the compatibilist, the truth of determinism does not preclude the existence of free will. (Even if we learned tomorrow that determinism is true, it might still be true that we have free will.) The philosophical problem of free will and determinism is the problem of understanding, how, if at all, the truth of determinism might be compatible with the truth of our belief that we have free will. That is, it's the problem of deciding who is right: the compatibilist or the incompatibilist. (shrink)

I draw upon Helen Steward's concept of agential settling to argue that freedom requires an ability to change the truth‐value of tenseless future contingents over time from false to true and that this ability requires a metaphysically open future.

In a recent paper I argued that agent causation theorists should be compatibilists. In this paper, I argue that compatibilists should be agent causation theorists. I consider six of the main problems facing compatibilism: (i) the powerful intuition that one can't be responsible for actions that were somehow determined before one was born; (ii) Peter van Inwagen's modal argument, involving the inference rule (β); (iii) the objection to compatibilism that is based on claiming that the ability to do otherwise is (...) a necessary condition for freedom; (iv) "manipulation arguments," involving cases in which an agent is manipulated by some powerful being into doing something that he or she would not normally do, but in such a way that the compatibilist's favorite conditions for a free action are satisfied; (v) the problem of constitutive luck; and (vi) the claim that it is not fair to blame someone for an action if that person was determined by forces outside of his or her control to perform that action. And in the case of each of these problems, I argue that the compatibilist has a much more plausible response to that problem if she endorses the theory of agent causation than she does otherwise.

In my paper I am concerned with Peter van Inwagen's Consequence Argument. I focus on its probably best known version. In this form it crucially employs the notion of rendering a proposition false, anotion that has never been made sufficiently clear. The main aim of my paper is to shed light on thisnotion. The explications offered so far in thedebate all are based on modal concepts. Iargue that for sufficient results a ``stronger'', hyper-intensional concept is needed, namely the concept expressed (...) by the word ``because''. I show that my analysis is superior to the prior ones. On the basis of this analysis I further explain why van Inwagen''s argument fails. (shrink)

This paper revisits a well-known rebuttal of Peter van Inwagen’s consequence argument. This CS-rebuttal, as I shall call it, focuses on the counterfactual structure of alternative possibilities. It shows that the ability to do otherwise is such that if the agent had exercised it, the distant past and/or the laws of nature would have been different. On the counterfactual scenario, there is, therefore, no need for the agent to exercise an ability to change the past or the laws of nature. (...) I first present van Inwagen’s original version of the consequence argument. After exposing some difficulties with Lewis’ famous version of the CS-rebuttal, I proceed by explaining and defending an older and, in my view, superior version. I subsequently discuss a traditional incompatibilist rejoinder, which insists that the past and the laws of nature are fixed. Although this rejoinder delivers a valid argument against the existence of alternative possibilities, it relies on premises the compatibilist explicitly rejects. The outcome of the debate is therefore properly characterized as a genuine dialectical stalemate between compatibilists and incompatibilists. In the final sections of the paper, I demonstrate that attempts by Fischer, Holliday and Fischer and Pendergraft to move beyond the stalemate in favor of the incompatibilist position all fail. I thereby show that the debate is marred by a misunderstanding of the semantics underlying the backtracking conditionals sometimes associated with the compatibilist position. In view of my arguments, the dialectical stalemate between compatibilists and incompatibilists regarding the counterfactual structure of the ability to do otherwise remains fully intact. (shrink)

The article is primarily concerned with the notion of a truth-maker. An explication for this notion is offered, which relates it to other notions of making something such-and-such. In particular, it is shown that the notion of a truth-maker is a close relative of a concept employed by van Inwagen in the formulation of his Consequence Argument. This circumstance helps understanding the general mechanisms of the concepts involved. Thus, a schematic explication of a whole battery of related notions is offered. (...) It is based on an explanatory notion, introduced by the sentential connector “because”, whose function is examined in some detail. Finally, on the basis of the explication proposed, an argument is developed to the effect that the objects usually regarded as truth-makers are not apt to play this role. (shrink)

The use of predicate and sentential operators to express the practical modalities -- ability, control, openness, etc. -- has given new life to a fatalistic argument against determinist theories of responsible agency. A familiar version employs the following principle: the consequences of what is unavoidable (beyond one's control) are themselves unavoidable. Accordingly, if determinism is true, whatever happens is the consequence of events in the remote past, or, of such events together with the laws of nature. But laws and the (...) remote past are not under our control and, by the principle, neither are their consequences. Therefore, none of our choices and actions, nor anything that results from them, is under our control.1 Whether refinements of the closure principle underlying this unavoidability argument are acceptable depends upon the precise sense of 'consequence' and 'unavoidable' involved. Roughly, a proposition P is a consequence of a set of propositions M iff it is impossible that P be false when each member of M is true, or, conversely, when M necessitates P. Since P is unavoidable for S when P is true and S is (was) unable to prevent P from being true, it might seem that if P is unavoidable the same should hold of what is necessitated by P. There is, in fact, 1 an easy defense of the principle which utilizes the incompatibilist condition that S is able to do action K only if it is as yet undetermined whether or not S will K. With it, there is no question but that one is unable to accomplish what is already determined by what one was unable to prevent. Of course, this reasoning is unlikely to impress the compatibilist who rejects the condition outright and, expectedly, it is not the procedure of the proponents of the unavoidability argument. The latter might rest content with appeals to intuition, but more significant are defenses of the closure principle and independent derivations of the unavoidability argument that rely upon distinct principles concerning the logic of the practical modalities, for example, closure of ability under entailment (Cross 1986, Brown 1988) or, claims about the "fixity of the past" and the "inescapability of laws" (Ginet 1990)..

I evaluate Patrick Todd's critique of the idea accepted by many, including (in contemporary philosophy) Nelson Pike and John Martin Fischer, that there can be non‐causal constraints on human actions (including basic actions). I suggest that Todd's critical reflections, although illuminating, are not persuasive. I defend non‐causal constraints in part by putting forward an interpretation of the intuitive idea of the fixity of the past following Carl Ginet: our freedom is the power to add to the given past.

The Blockage Argument is designed to improve upon Harry Frankfurt’s famous argument against the Principle of Alternative Possibilities by removing the counterfactual intervener altogether. If the argument worked, then it would prove in a way that Frankfurt’s argument does not that moral responsibility does not require any alternative possibilities whatsoever, not even the weakest “flicker of freedom”. -/- Some philosophers have rejected the Blockage Argument solely on the basis of their intuition that the inability to do otherwise is incompatible with (...) moral responsibility. I will argue, however, that it is not merely the inability to do otherwise by itself but rather the inability to do otherwise in combination with the absence of a counterfactual intervener that is incompatible with moral responsibility. If I cannot do otherwise and it is not because of a counterfactual intervener, then it must be the case that I am being forced to choose and therefore act as I do, in which case I cannot be morally responsible for this action. -/- Because the Blockage Argument fails, and because it was really the only way to establish that moral responsibility does not require any alternative possibilities whatsoever, it follows that moral responsibility does indeed require at least one alternative possibility in any given situation. But it turns out that this conclusion does not tip the balance in favor of incompatibilism over compatibilism. It would have if blockage and determinism were equivalent. But they are not. Unlike blockage, determinism is compatible with certain counterfactuals that compatibilists traditionally believed the ability to do otherwise reduces to. So even though moral responsibility is incompatible with blockage, it does not necessarily follow that moral responsibility is incompatible with determinism. (shrink)

The author presents a model of moral responsibility based on the actual sequence and the notion of reason-responsiveness, and draws an analogy between this model and Robert Nozick’s model of knowledge based on the actual sequence. In addition, the concept of semicompatibilism is introduced and explained.

Christopher Taylor has greatly clarified my thinking on this topic and shown me how to launch a deeper and more radical campaign in support of my earlier claims to this effect, and our coauthored paper (Taylor and Dennett 2001) provides more technical detail than is needed here. Here I will attempt a gentler version of our argument, highlighting the main points so that non-philosophers can at least see what the points of contention are, and how we propose to settle them, (...) while leaving out almost all the logical formulae. Philosophers should consult the full-dress version, of course, to see if we have actually tied off the loose ends, and closed the loopholes that are passed by without mention in this telling.
