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.

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)

The Consequence Argument is a staple in the defense of libertarianism, the view that free will is incompatible with determinism and that humans have free will. It is often thought that libertarianism is consistent with a certain naturalistic view of the world — that is, that libertarian free will can be had without metaphysical commitments beyond those pro- vided by our best (indeterministic) physics. In this paper, I argue that libertarians who endorse the Consequence Argument are forced to reject this (...) naturalistic worldview, since the Consequence Argument has a sis- ter argument — I call it the Supervenience Argument — which cannot be rejected without threatening either the Consequence Argument or the naturalistic worldview in question.

The role of causation and counterfactuals in causal decision theory is vexed and disputed. Recently, Brian Hedden (2023) argues that we should abandon causal decision theory in favour of an alternative: counterfactual decision theory. I argue that, pace Hedden, counterfactual decision theory is not a competitor to, but rather a version of, causal decision theory – the most popular version by far. I provide textual evidence that the founding fathers of causal decision theory (Stalnaker, Gibbard, Harper, Lewis, Skyrms, Sobel, and (...) Joyce) all endorse counterfactual decision theories. I additionally discuss why these theories came to be called ‘causal’, rather than ‘counterfactual’. And I argue that, properly understood, causal decision theory escapes Hedden's objections.

Thinking About Free Will. By Van Inwagen Peter.

In this paper, I present an argument that shows that the belief in libertarian freedom is inconsistent with two assumptions widely accepted by those who are physicalists with regard to the relation between the mental and the physical - that mental properties are distinct from physical properties, and that mental properties supervene on physical properties. After presenting the argument, I trace its implications for the question of the compatibility of libertarian free will and physicalism in general.

The consequence argument purports to show that determinism is true only if no one has free will. Judgments about whether the argument is sound depend on how one understands locutions of the form 'p and no one can render p false'. The main interpretation on offer appeals to counterfactual sufficiency: s can render p false just in case there is something s can do such that, were s to do it, p would be false; otherwise, s cannot render p false. (...) Here I show that, in the context of the consequence argument, this interpretation conflicts with widely endorsed principles governing the logic of counterfactuals. (shrink)

Besides pure declarative arguments, whose premises and conclusions are declaratives (“you sinned shamelessly; so you sinned”), and pure imperative arguments, whose premises and conclusions are imperatives (“repent quickly; so repent”), there are mixed-premise arguments, whose premises include both imperatives and declaratives (“if you sinned, repent; you sinned; so repent”), and cross-species arguments, whose premises are declaratives and whose conclusions are imperatives (“you must repent; so repent”) or vice versa (“repent; so you can repent”). I propose a general definition of argument (...) validity: an argument is valid exactly if, necessarily, every fact that sustains its premises also sustains its conclusion, where a fact sustains an imperative exactly if it favors the satisfaction over the violation of the imperative, and a fact sustains a declarative exactly if, necessarily, the declarative is true if the fact exists. I argue that this definition yields as special cases the standard definition of validity for pure declarative arguments and my previously defended definition of validity for pure imperative arguments, and that it yields intuitively acceptable results for mixed-premise and cross-species arguments.

I explore some issues in the logics and dialectics of practical modalities connected with the Consequence Argument (CA) considered as the best argument for the incompatibility of free will and determinism. According to Lewis (1981) in one of the possible senses of (in)ability, the argument is not valid; however, understood in the other of its possible senses, the argument is not sound. This verdict is based on the assessment of the modal version of the argument, where the crucial notion is (...) power necessity (“no choice” operator), while Lewis analyses the version where the central notion is the locution “cannot render false.”Lewis accepts closure of the relevant (in)ability operator under entailment but not closure under implication. His strategy has a seemingly strange corollary: a free predetermined agent is able (in a strong, causal sense) to falsity the conjunction of history and law. I compare a Moorean position with respect to radical skepticism and knowledge closure with ability closure and propose to explain Lewis’s strategy in the framework of his Moorean stance. (shrink)

Modal arguments for incompatibility of freedom and determinism are typically based on the “transfer principle” for inability to act otherwise (Beta). The principle of agglomerativity (closure under conjunction introduction) is derivable from Beta. The most convincing counterexample to Beta is based on the denial of Agglomeration. The defender of the modal argument has two ways to block counterexamples to Beta: (i) use a notion of inability to act otherwise which is immune to the counterexample to agglomerativity; (ii) replace Beta with (...) a logically stronger principle Beta 2. I argue that the second strategy fails because the strengthened principle and Agglomeration together entail Beta. So this strategy makes sense only if Beta 2 is applied without Agglomeration. But if Beta 2 is used without Agglomeration, then the incompatibilist will undercut the rationale for the premise of his argument. I illustrate this point with the analysis of Warfield (1996) and his use of Beta 2 in the so called direct argument for incompatibilism. (shrink)

Carlos Vaz Ferreira argues that the problem of freedom is conceptually distinct from the problem of causal determinism. The problem of freedom is ultimately a problem regarding the ontologically independent agency of a being, and the problem of determinism is a problem regarding explanations of events or acts in terms of the totality of their antecedent causal conditions. As Vaz Ferreira sees it, failing to keep these problems apart gives rise to merely apparent but unreal puzzles pertaining to the nature (...) of freedom and its relation to determinism. In this article, I present my interpretation of Vaz Ferreira’s distinctive ideas regarding the nature of freedom and its relation to casual determinism. (shrink)

Peter van Inwagen has developed two highly influential strategies for establishing incompatibilism about causal determinism and moral responsibility. These have come to be known as ‘the Direct Argument’ and ‘the Indirect Argument,’ respectively. In recent years, the two arguments have attracted closely related criticisms. In each case, it is claimed, the argument does not provide a fully general defense of the incompatibilist’s conclusion. While the critics are right to notice these arguments’ limitations, they have not made it clear what the (...) problem with the arguments is supposed to be. I suggest three possibilities, arguing that none proves to be well founded. I conclude that the scope of these arguments is fully adequate for their defenders’ purposes. (shrink)

Michael Lynch’s Truth as One and Many is a contribution to the large body of philosophical literature on the nature of truth. Within that genre, advocates of truth-as-correspondence, advocates of truth-as-coherence, and the like, all hold that truth has a single underlying metaphysical nature, but they sharply disagree as to what this nature is. Lynch argues that many of these views make good sense of truth attributions for a limited stretch of discourse, but he adds that each of the contenders (...) also faces a ‘scope problem’, in that none of them makes sense of all legitimate truth attributions. Some deflationists make similar observations – usually less concessive – and conclude that truth simply has no substantial, underlying nature. There is nothing for the philosopher to articulate and defend. Lynch agrees with deflationists that the realm of discourse is too diverse for any single ‘first-level’ property, such as correspondence or coherence, to fully characterize it, but against deflationism, he holds that truth does have a nature. He presents a functionalist theory. The definition is this: x is true if, and only if, x has a property that plays the truth-role. According to Lynch, the truth-role is given in terms of what he calls the ‘core truisms’ of the folk concept of truth. These are platitudes that hold of the everyday notion, and are such that anyone who denies all of them can be accused of changing the subject – of not talking about truth. A given property T plays the truth-role for a batch of propositions, just in case, for any proposition P in the batch: P is T if, and only if, where P is believed, things are as they are believed to be; other things being equal, it is a worthy goal ….

Among challenges to libertarians, the _Mind_ Argument has loomed large. Believing that this challenge cannot be met, Peter van Inwagen, a libertarian, concludes that free will is a mystery. Recently, the _Mind_ Argument has drawn a number of criticisms. Here I seek to add to its woes. Quite apart from its other problems, I argue, the _Mind_ Argument does a poor job of isolating the important concern for libertarians that it raises. Once this concern has been clarified, however, another argument (...) serves to renew the challenge. The Assimilation Argument challenges libertarians to explain how ostensible exercises of free will are relevantly different from other causally undetermined outcomes, outcomes that nobody would count as exercises of free will. In particular, libertarians must explain how agents can have the power to settle which of two causally possible futures becomes the actual future. This will require them to distinguish cases where this power is supposedly present from similar cases where it’s clearly absent. (shrink)

Claims about freedom and predestination are ubiquitous in movies, novels, and myths. These claims touch upon the philosophical problem of the compatibility of free will and determination. In order to make an informed judgment about whether these claims are true, it is helpful to know what philosophers have to say about free will. However, philosophical discussions are usually absent in popular culture. It is perhaps no wonder, since free will is a topic that has been discussed for millennia. Consequently, these (...) discussions have become quite complicated and not easy to decipher. This essay is a popular introduction to these discussions, accessible to readers without former acquaintance with the topic. I provide references to other works for readers interested in knowing more. My aim is to show that while there are persuasive arguments against free will, there are no fewer persuasive replies to these arguments. Free will is a fascinating topic, and I hope that acquaintance with the relevant philosophical discussion will prove useful for those who wonder if anyone is free to create their own destiny.

According to the Consequence Argument, the truth of determinism plus other plausible principles would yield the conclusion that we have no free will. In this paper I will argue that the conception of determinism typically employed in the various versions of the Consequence Argument is not plausible. In particular, I will argue that, taken most straightforwardly, determinism as defined in the Consequence Argument would imply that the existence of God is logically impossible. This is quite an implausible result. The truth (...) or falsity of determinism is typically taken to be a contingent, empirical matter. But how could the empirical discovery that determinism is true lead to the conclusion that God’s existence is a logical impossibility? The defender of the Consequence Argument can avoid this conclusion, but only at the cost of making other similarly implausible claims. The objection.. (shrink)

Traditional compatibilism about free will is widely considered to be untenable. In particular, the conditional analysis of the ability to do otherwise appears to be subject to clear counterexamples. I will propose a new version of traditional compatibilism that provides a conditional account of both the ability to do otherwise and the ability to choose to do otherwise, and I will argue that this view withstands the standard objections to traditional compatibilism. For this, I will assume with incompatibilists that the (...) mere possession of a general ability to do otherwise is not sufficient for having the ability that is required for free will. This concession distinguishes the view from the traditional conditional analysis and from recent dispositional accounts of the ability to do otherwise, and we will see that this concession enables a straightforward response to the counterexamples. This, in turn, will play a crucial role in my response to the strongest version of the consequence argument for incompatibilism. (shrink)

The Conjunction Principle says, roughly, that if the truth of a conjunction can be brought about, then the truth of each conjunct can be brought about. The current essay argues that this principle is not valid. After a clarification of the principle, it is shown how a proper understanding of the involved notions falsify the principle. As a corollary, a recent attack on van Inwagen’s Consequence Argument will be rebutted, because it relies on the invalid conjunction principle.

The main goal of this paper is to contribute to the clarification of the dialectics between compatibilists and incompatibilists on free action. I describe a new incompatibilist position that has been neglected in the literature. I also provide a proper rationale for such a position. First, I present a justification for incompatibilism that is composed of an old idea and a new one. The old idea is the FRAP principle: freedom requires alternative possibilities. Compatibilists and incompatibilists alike usually share a (...) Key Assumption about how the open alternative possibilities allowed by indeterminism are supposed to support the libertarian case: the existence of alternative possibilities should make a metaphysically relevant difference concerning the control and/or the authorship of the agent over the action. The other component in the justification for incompatibilism is the rejection of the Key Assumption. Why to preserve FRAP when the Key Assumption is dropped? The answer has three parts: we have a strong pre-theoretical intuition in favour of FRAP; a crucial anti-libertarian argument, known as the Luck Argument, can be interpreted as showing that FRAP and the Key Assumption cannot both be true; the Luck Argument doesn't work when directed against FRAP itself.

Suppose that time t is just a few moments from now. And suppose that the proposition that Jones sits at t was true a thousand years ago. Does the thousand-years-ago truth of that proposition imply that Jones's upcoming sitting at t will not be free? This article argues that it does not. It also argues that Jones even now has a choice about the thousand-years-ago truth of that Jones sits at t . Those arguments do not require the complex machinery (...) of Ockhamism, with its distinction between hard facts and soft facts; indeed, those arguments do not require any complex machinery at all. Instead, those arguments are built on an uncontroversial understanding of the idea that truth depends on the world. In the final section of the article, those arguments are extended to show that foreknowledge of an action does not threaten that action's freedom. (shrink)

In debates concerning the consequence argument, it has long been claimed that [McKay, T. J., and D. Johnson. 1996. “A Reconsideration of an Argument Against Compatibilism.” Philosophical Topics 24 (2): 113–122] demonstrated the invalidity of rule (β). Here, I argue that their result is not as robust as we might like to think. First, I argue that McKay and Johnson's counterexample is successful if one adopts a certain interpretation of ‘no choice about’ and if one is willing to deny the (...) conditional excluded middle principle. In order to make this point I demonstrate that (β) is valid on Stalnaker's theory of counterfactuals. This result is important and should not be neglected, I argue, because there is a particular line of objection to the revised formulations of the consequence argument that does not succeed against the original version.

Rigidity does interesting philosophical work, with important consequences felt throughout metaphysics, epistemology, philosophy of mind, and so on. The authors’ aim in this article is to show that rigidity has yet another role to play, with surprising consequences for the problem of free will and determinism, for the phenomenon of rigidity has the upshot that some metaphysically necessary truths are up to us. The significance of this claim is shown in the context of influential arguments against free will. The authors (...) show that some virtually indisputable inference rules employed in formulations of the Consequence Argument, as well as in fatalistic arguments, fail with a variety of counter-examples. Along the way, the authors compare the present arguments to other, similar arguments made in recent years. (shrink)

In this review, I discuss some aspects of van Inwagen’s insights with respect to the notions of free will and determinism. My main focus is on the author’s formulation of the free will problem.

In this paper, I challenge the Consequence Argument for Incompatibilism by arguing that the inference principle it relies upon is not well motivated. The sorts of non-question-begging instances that might be offered in support of it fall short.

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.

I make a case for the thesis that no one can refrain from trying to attain the object of his or her currently strongest desire. I arrive there by defending an argument by Peter van Inwagen for a relatively mild conclusion about the way desires limit our abilities, and by arguing that if van Inwagen’s conclusion is correct, and correct for his reasons, so is my bolder thesis. I close with replies to objections, such as the objection that it is (...) better to take my argument as a reductio ad absurdum of van Inwagen’s than to take my conclusion seriously. (shrink)

A growing consensus in the literature on agentive modals has it that ability modals like ‘can’ or ‘able to’ have a _dual_, i.e. interpretations of ‘must’ or ‘cannot but’ which stand to _necessity_ as ability stands to _possibility_. We argue that this thesis (which we call ‘Agentive Duality’) is much more controversial than meets the eye. While Agentive Duality follows from the orthodox possibility analysis of ability given natural assumptions, it sits uneasily with a wide range of alternative proposals which (...) are unified by the idea that ability requires _control_. In particular, we show that against the background of a control requirement on ability, Agentive Duality can be used to derive absurd predictions featuring this dual. Far from being a purely definitional thesis, Agentive Duality thus affords a new lens through which to assess the long-standing debate between possibility analyses of ability and their discontents.

In this article we survey six recent developments in the philosophical literature on free will and moral responsibility: (1) Harry Frankfurt's argument that moral responsibility does not require the freedom to do otherwise; (2) the heightened focus upon the source of free actions; (3) the debate over whether moral responsibility is an essentially historical concept; (4) recent compatibilist attempts to resurrect the thesis that moral responsibility requires the freedom to do otherwise; (5) the role of the control condition in free (...) will and moral responsibility, and finally (6) the debate centering on luck.

In a recent paper, Pruss proves the validity of the rule beta-2 relative to Lewis’s semantics for counterfactuals, which is a significant step forward in the debate about the consequence argument. Yet, we believe there remain intuitive counter-examples to beta-2 formulated with the actuality operator and rigidified descriptions. We offer a novel and two-dimensional formulation of the Lewisian semantics for counterfactuals and prove the validity of a new transfer rule according to which a new version of the consequence argument can (...) be formulated. This new transfer rule is immune to the counter-examples involving the actuality operator and rigidified descriptions. However, we show that counter-examples to this new rule can also be generated, demanding that the Lewisian semantics be generalized for higher dimensions where counter-examples can always be generated.

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)

No contemporary compatibilist account of free will can be complete unless it engages with the consequence argument. I will argue that Wilfrid Sellars offered an ingenious version of compatibilism that can be used to refute the consequence argument. Unfortunately, owing to the opacity of Sellars’s writings on free will, his solution has been neglected. I will reconstruct his view here, demonstrating how it represents a powerful challenge to the consequence argument and tying it to some recent developments in the compatibilist (...) literature.

Many philosophers and non-philosophers who reflect on the causal antecedents of human action get the impression that no agent can have morally relevant freedom. Call this the ‘non-existence impression.’ The paper aims to understand the (often implicit) reasoning underlying this impression. On the most popular reconstructions, the reasoning relies on the assumption that either an action is the outcome of a chance process, or it is determined by factors that are beyond the agent’s control or which she did not bring (...) about. I argue that arguments based on this premise fail to apply to some possible agents for whom the non-existence impression arises. On the alternative reconstruction I offer, the impression rests on the assumption that free will requires being involved in the ultimate explanation of one’s actions in a novel sense in which nothing can be involved in the ultimate explanation of anything.

In his recent book Willensfreiheit Geert Keil defends a version of libertarianism. Yet he criticizes a flagship argument for incompatibilism. Van Inwagen's consequence argument, Keil thinks, relies on an irrelevant premise when it claims that agents have no choice about the remote past. I argue that Keil's charge rests on a misunderstanding. I then sketch why discussions of the consequence argument should focus on the question whether or not a certain version of rule Beta is valid.

This paper offers a new argument for compatibilism about moral responsibility by drawing attention to some overlooked implications of incompatibilism. More specifically, I argue that incompatibilists are committed to some unsavory claims about pairs of agents in deterministic worlds. These include comparative claims about moral responsibility, blameworthiness, desert, punishment, and the fittingness of reactive attitudes. I argue that we have good reasons to reject such comparisons because they fail to account for key differences between deterministic agents. This provides us with (...) reason to embrace compatibilism and reject incompatibilism. (shrink)

The aim of my paper is to compare three alternative formal reconstructions of van Inwagen’s famous argument for incompatibilism. In the first part of my paper, I examine van Inwagen’s own reconstruction within a propositional modal logic. I point out that, due to the expressive limitations of his propositional modal logic, van Inwagen is unable to argue directly (that is, within his formal framework) for incompatibilism. In the second part of my paper, I suggest to reconstruct van Inwagen’s argument within (...) a first-order predicate logic. I show, however, that even though this reconstruction is not susceptible to the same objection, this reconstruction can be shown to be inconsistent (given van Inwagen’s own assumptions). At the end of my paper, I suggest to reconstruct van Inwagen’s argument within a quantified counterfactual logic with propositional quantifiers. I show that within this formal framework van Inwagen would not only be able to argue directly for incompatibilism, he would also be able to argue for crucial assumptions of his argument. (shrink)

Peter van Inwagen’s original formulation of the Consequence Argument employed an inference rule that was shown to be invalid given van Inwagen’s interpretation of the modal operators in the Consequence Argument. In response, van Inwagen recently suggested a revised interpretation of his modal operators. Following up on a debate between Blum and Schnieder, I analyze van Inwagen’s revised interpretation in terms of explanatory notions and I argue that van Inwagen faces a dilemma: he either has to admit that beta entails (...) fatalism, or he has to admit that a new counterexample invalidates beta. Either way, it seems reasonable to reject beta and to conclude that the Consequence Argument fails. Further, I argue that Widerker’s well-known substitute for rule beta is faced with a similar dilemma and, therefore, is bound to fail as well. I conclude that, if the modal operators are interpreted in terms of explanatory notions, neither van Inwagen’s nor Widerker’s rule of inference turns out to be valid. (shrink)

The aim of the Consequence Argument is to show that, if determinism is true, no one has, or ever had, any choice about anything. In the stock version of the argument, its two premisses state that no one is, or ever was, able to act so that the past would have been different and no one is, or ever was, able to act so that the laws of nature would have been different. This stock version fails, however, because it requires (...) an invalid inference rule. The standard response is to strengthen both premisses by replacing ‘would’ with ‘might’. While this response ensures validity, it weakens the argument, since it strengthens the premisses. I show that we can do better: We can keep the weak reading of one premiss and just strengthen the other. This provides two versions of the Consequence Argument which are stronger than the standard revision. (shrink)

The Mind Argument is an argument for the incompatibility of indeterminism and anyone's having a choice about anything that happens. Peter van Inwagen rejects the Mind Argument not because he is able to point out the flaw in it, but because he accepts both that determinism is incompatible with anyone's having a choice about anything that happens and that it is possible for someone to have a choice about something that happens. In this paper I first diagnose and clear up (...) a confusion in recent discussions of the Mind Argument and then go on to show why it is a bad argument. (shrink)

Arguments for Restrictivism – the position that we are rarely free– have been proposed by incompatibilists Peter van Inwagen and David Vander Laan among others. This article is concerned much more with these arguments than with quantifying the frequency of free actions. There are two general ways to argue for restrictivism. First, one may take a Negative Strategy, arguing that the situations in which one is not free are common and predominant. Second, one may focus on situations in which one (...) is apparently free, and argue directly that these situations are rare – the Inventory Strategy. I conclude that both types of arguments for restrictivism are unconvincing. (shrink)

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.
