An increasingly popular approach to reconciling divine foreknowledge with human freedom is to say that, because God’s beliefs depend on what we do, we are free to do otherwise than what we actually do despite God’s infallible foreknowledge. This paper develops a new challenge for this dependence response. The challenge stems from a case of backward time travel in which an agent intuitively lacks the freedom to do otherwise because of the time-traveler’s knowledge of what the agent will do, and (...) this is so despite the fact that the time-traveler’s knowledge depends on what the agent will do.

Strong notions of free will are closely connected to the possibility to do otherwise as well as to an agent’s ability to causally influence her environment via her decisions controlling her actions. In this paper we employ techniques from the causal modeling literature to investigate whether a notion of free will subscribing to one or both of these requirements is compatible with naturalistic views of the world such as non-reductive physicalism to the background of determinism and indeterminism. We argue that (...) from a causal modeler’s perspective the only possibility to get both requirements consists in subscribing to reductive physicalism and indeterminism. (shrink)

The consequence argument is widely regarded as the most important argument for incompatibilism. In this paper, I argue that, although the consequence argument may be sound in its standard formulations, it does not support any thesis that could reasonably be called ‘incompatibilism’.

If mental illnesses are externally constituted, then so are somatic illnesses. Will Davies makes a persuasive case for externalism in psychiatry; as I show here, parallel examples exist in somatic medicine.

The compatibility of determinism and the ability to do otherwise has been implicitly assumed by many to be irrelevant to the viability of compatibilist responses to the manipulation argument for incompatibilism. I argue that this assumption is mistaken. The manipulation argument may be unsound. But even so, the manipulation argument, at the very least, undermines classical compatibilism, the view that free will requires the ability to do otherwise, and having that ability is compatible with determinism. This is because classical compatibilism, (...) in conjunction with any type of reply to the manipulation argument, has counterintuitive implications. In order to avoid such implications, we need not hold that determinism is incompatible with moral responsibility. But we must hold that determinism is incompatible with the ability to do otherwise.

Perszyk has argued that Molinists cannot consistently endorse the consequence argument because of a structurally similar argument for the incompatibility of true Molinist counterfactuals of freedom and the ability to do otherwise. Wierenga has argued that on the proper understanding of CCFs, there is a relevant difference between the consequence argument and the anti-Molinist argument. I argue that, even on Wierenga’s understanding of CCFs, there is in fact no relevant difference between the two arguments. Moreover, I strengthen Perszyk’s challenge by (...) highlighting further relevant similarities between CCFs and facts about the laws. (shrink)

Traditionally, incompatibilists about moral responsibility and determinism claim that we cannot be morally responsible unless we could have done otherwise and that we cannot do otherwise if we are determined. The Direct Argument for incompatibilism supposedly offers its defenders a dialectical advantage over this traditional approach insofar as it does not appear to rely on either of these controversial claims. Recently, though, David Widerker has argued against this supposition and urged that it is time to say farewell to the Direct (...) Argument. I examine two of Widerker’s criticisms and argue that, while they are not compelling, a revised version of one does show that supporters of the Direct Argument will very likely need to deny that an agent could do otherwise if determinism is true. I conclude that, nevertheless, the Direct Argument may still have considerable dialectical appeal and that neither of Widerker’s criticisms should lead us to say goodbye to it just yet. (shrink)

According to the Principle of the Fixity of the Past (FP), no one can now do anything that would require the past to have unfolded differently than it actually did, for the past is fixed, over and done with. Why might doing something in the future require the past to be different? Because if determinism is true—if the laws of nature and the initial conditions of the Big Bang determined a unique future for our universe—then doing anything other than what (...) you are determined to do would require one of two things: either a miracle, a violation of the actual laws of nature, or a different past, all the way back to the Big Bang or beyond. Which would it be? Those who reject miracles accept a Backtracking Principle (BT), according to which the past would (have to) be different. If this is correct, then it follows by (FP) that you cannot now do anything other than what you are determined to do. The conclusion of this much-discussed argument is that the freedom to do otherwise is incompatible with determinism. In order to break a stalemate between incompatibilists and compatibilists in the debate over (FP), this article presents a new Action-Type Argument for (FP). The aim is to refute Backtracking Compatibilism, the view that (BT) is true and yet the freedom to do otherwise is compatible with determinism. The form of the Action-Type Argument for (FP) also leads to a Simple Argument for incompatibilism, which does not assume (BT). What the Simple Argument does assume is a “governing” view of laws of nature, a view of laws as more than mere regularities that turn out to be exceptionless over all time. Incompatibilism follows.

A crucial question for libertarians about free will and moral responsibility concerns how their accounts secure more control than compatibilism. This problem is particularly exasperating for event-causal libertarianism, as it seems that the only difference between these accounts and compatibilism is that the former require indeterminism. But how can indeterminism, a mere negative condition, enhance control? This worry has led many to conclude that the only viable form of libertarianism is agent-causal libertarianism. In this paper I show that this conclusion (...) is premature. I explain how event-causal libertarianism secures more control than compatibilism by offering a novel argument for incompatibilism. Part of the reason my solution has gone unnoticed is that it is often mistakenly assumed that an agent's control is wholly exhausted by the agent's powers and abilities. I argue, however, that control is constituted not just by what we have the ability to do, but also by what we have the opportunity to do. And it is by furnishing agents with new opportunities that event-causal libertarianism secures enhanced control. In order to defend this claim, I provide an analysis of opportunities and construct a novel incompatibilist argument to show that the opportunity to do otherwise is incompatible with determinism.

In conclusion, then, the notion of temporal necessity is certainly queer and perhaps a misnomer. It really has little to do with temporality per se and everything to do with counterfactual openness or closedness. We have seen that the future is as unalterable as the past, but that this purely logical truth is not antithetical to freedom or contingency. Moreover, we have found certain past facts are counterfactually open in that were future events or actualities to be other than they (...) will be, these past facts would have been different as a consequence. God's beliefs about the future are such past facts. Moreover, the effects of actions which God would have taken had He believed differently are also such past facts. Oddly enough, then, virtually any past fact is potentially counterfactually open, and the only necessity that remains is purely de facto. We, of course, do not in general know which events of the past depend counterfactually on present actions, and those cases we do know about seem rather trivial. Our intuitions of the necessity, unalterability, and unpreventability of the past as opposed to the future stem from the impossibility of backward causation, which is precluded by the dynamic nature of time and becoming. But the counterfactual dependence of God's beliefs on future events or actualities is not a case of backward causation: rather future-tense propositions are true in virtue of what will happen, given a view of truth as correspondence, and God simply has the essential property of knowing all and only true propositions. With regard to the future, virtually all facts are counterfactually open, and therefore future-tense propositions are not temporally necessary. Propositions thus move from being temporally contingent to being temporally necessary when all the opportunities to affect things counterfactually have slipped by. Hence, the mere fact that an event is past is no indication that it is counterfactually closed. This is especially evident in the case of God's foreknowledge. If we say that God foreknows that I shall do x and therefore I cannot refrain from doing x, lest I change God's past foreknowledge, we are being deceived by a modality which has nothing to do with my power or freedom. All that is impossible is the conjunction of God's foreknowledge that p and of ~ p; but this modality in sensu composito has no bearing on my ability to act such that ~ p would be true and God would have foreknown differently. Temporal necessity, then, turns out to be only obliquely temporal and modally weak, certainly no threat to freedom or divine foreknowledge. (shrink)

Peter van Inwagen contends that nonresponsibility transfers across deterministic relations. Suppose it does. If the facts of the past and the laws of nature entail every truth about what one does, and no one is even in part morally responsible for the past and the laws, then no one is even in part morally responsible for what one does. This argument, the Direct Argument, has drawn various critics, who have attempted to produce counterexamples to its core inference principle. This article (...) considers two notable efforts, one by John Martin Fischer and Mark Ravizza and another by David Widerker. It shows that neither is sufficient to reject the Direct Argument. The article then proceeds to challenge the argument in a novel fashion. Van Inwagen has not given us good reason to think that the principle in question has an adequate anchor in our inferential practices, especially in light of the dialectical context with the compatibilist. Hence, it is not the compatibilists' burden to produce counterexamples to it. Rather, it is van Inwagen's burden to produce relevant confirming instances of it. (shrink)

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.

What does it tell us about the compatibility of freedom and determinism to recognize that, while acting freely, we typically have good reasons for whatever we are doing? More than it seems, I suppose. In this paper, it is argued that two well‐established accounts of human freedom—libertarianism and local miracle compatibilism—understate the connection between reasons and actions, leaving us only with the causal part of the explanation. This is so because on the basis of these views, a majority of alternate (...) actions relevant for the ascription of the ability to do otherwise turn out to be either unreasonable or irrational. Hence, by denying that free agents possess an ability to do otherwise rationally, these accounts fail to provide an adequate characterization of free action. Then, it is shown that the necessary requirement of reasons‐responsiveness may be satisfied by the altered‐reasons analysis of the ability to do otherwise. This particular kind of multiple‐past compatibilism, while providing a plausible response to the incompatibilist argument, also corresponds to a version of conditional analysis that is resistant to the classical objections to desire‐, choice‐, or try‐based conditionalism.
