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)

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.

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)

Many philosophers hold that luck excludes control-more precisely, that an event is lucky for you only if that event lies beyond your control. Call this the Lack of Control Requirement (LCR) on luck. Jennifer Lackey [2008] has recently argued that there is no such requirement on luck. Should such an argument succeed, it would (among other things) disable a main objection to the "libertarian" position in the free will debate. After clarifying the LCR, I defend it against both Lackey's argument (...) and a novel argument different in kind from Lackey's. I undermine each of these arguments by sketching a plausible error theory for its key intuition. For each argument, there's a natural reply available to its proponents. I show that these natural replies depend on certain mistaken general principles about luck. Neither Lackey's argument nor the novel argument I consider casts serious doubt on the LCR.

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 Consequence Argument for incompatibilism is beset by two rival interpretations: the counterfactual sufficiency interpretation and the counterfactual might interpretation. Waldrop recently argued that the counterfactual sufficiency interpretation conflicts with certain principles governing the logic of counterfactuals. In this paper, I show that Waldrop’s argument can be adapted to prove that the counterfactual might interpretation also conflicts with the same principles. So the problem Waldrop pointed out is not peculiar to the counterfactual sufficiency interpretation.

In recent papers, Philip Swenson (2016) has argued that presentism is incompatible with the conjunction of libertarianism and divine foreknowledge, and Michael Rea (2006) has argued that presentism is incompatible with the conjunction of libertarianism and bivalence. In this paper, I respond to Swenson’s and Rea’s arguments. In each case, I develop a parody argument that seeks to show that actualism -- the view that everything is actual -- is inconsistent with the conjunction of (in the case of Rea) libertarianism (...) and bivalence and the conjunction of (in the case of Swenson) libertarianism and divine foreknowledge. Seeing how these parody arguments using actualism go wrong helps us see how the arguments using presentism go wrong. I conclude that we have not yet been provided with a sound argument that presentism is inconsistent with the conjunction of libertarianism and bivalence or that presentism is inconsistent with the conjunction of libertarianism and divine foreknowledge.

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)

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.

Christian List has recently constructed a novel formal framework for representing the relationship between free will and determinism. At its core is a distinction between physical and agential levels of description. List has argued that, since the consequence argument cannot be reconstructed within this framework, the consequence argument rests on a ‘category mistake’: an illicit conflation of the physical and agential levels. I show that an expanded version of List’s framework allows the construction of a cross-level consequence argument.

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)

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)

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)

In this paper we raise three questions of clarification about Alfred Mele's fine recent book, Free Will and Luck. Our questions concern the following topics: (i) Mele's combination of 'luck' and 'Frankfurt-style' objections to libertarianism, (ii) Mele's stipulations about 'compatibilism' and the relation between questions about free action and questions about moral responsibility, and (iii) Mele's treatment of the Consequence Argument.

Daniel C. Dennett has long maintained that the Consequence Argument for incompatibilism is confused. In a joint work with Christopher Taylor, he claims to have shown that the argument is based on a failure to understand Logic 101. Given a fairly plausible account of having the power to cause something, they claim that the argument relies on an invalid inference rule. In this paper, I show that Dennett and Taylor’s refutation does not work against a better, more standard version of (...) the Consequence Argument. Therefore, Dennett and Taylor’s alleged refutation fails. (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.

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)

Besides pure declarative arguments, whose premises and conclusions are declaratives, and pure imperative arguments, whose premises and conclusions are imperatives, there are mixed-premise arguments, whose premises include both imperatives and declaratives, and cross-species arguments, whose premises are declaratives and whose conclusions are imperatives or vice versa. 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 proposition 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.

The well‐known “Consequence Argument” for the incompatibility of freedom and determinism relies on a certain rule of inference; “Principle Beta”. Thomas Crisp and Ted Warfield have recently argued that all hitherto suggested counterexamples to Beta can be easily circumvented by proponents of the Consequence Argument. I present a new counterexample which, I argue, is free from the flaws Crisp and Warfield detect in earlier examples.
