Incompatibilism

Many Compatibilists seem to suppose that discover that we lived in a deterministic world would not unseat our confidence that many of our actions are nevertheless free. Here's a short story about such confidence becoming unseated.

In his seminal essay, Harry Frankfurt argued that our exercise of free will and allocation of moral responsibility do not depend on us being able to do other than we did. Leslie Allan defends this moral maxim from Frankfurt's attack. Applying his character-based counterfactual conditional analysis of free acts to Frankfurt's counterexamples, Allan unpacks the confusions that lie at the heart of Frankfurt's argument. The author also explores how his 4C compatibilist theory measures up against Frankfurt’s conclusions.

The author mounts a case against the libertarian and hard determinist's thesis that free will is impossible in a deterministic world. He charges incompatibilists with misconstruing ordinary 'free will' talk by overlaying common language with their own metaphysical presuppositions. Through a review of ordinary discourse and recent developments in jurisprudence and the sciences, he draws together the four key factors required for an act to be free. He then puts his 4C theory to work in giving a credible account of (...) how caused human agents 'could have done otherwise'. (shrink)

If I take a free decision, how does this express itself physically? If God acts in this world, how does he do so? The answers to those two questions may be different or the same. Here we sketch a typology of possible answers, including Transcendent Compatibility. It turns out that in an open universe, freedom is the timewise mirror image of causality.

According to Joseph Campbell's "No Past Objection" (NPO), popular formal statements of the Consequence Argument are oddly silent about the freedom status of actors who lack a “remote past,” a time prior to their birth at which their universe existed but they did not. As such, NPO problematizes the common view that the Consequence Argument concludes that determinism (perhaps in combination with other things) conflicts with or poses some kind of threat to free will. In this essay, I present a (...) new "explanatory gap objection" to the Consequence Argument which sheds new light on a problem only hinted at in extant work on NPO. As part of this project, I show that NPO misses its mark when targeted at van Inwagen's original logic-text statements of the Consequence Argument, for these arguments must be interpreted given the background assumptions of the classical analytic paradigm in which van Inwagen and his peers were working. However, when the Consequence Argument is unmoored from its original (and now degenerate) paradigm, this argument may be developed as an argument for its original conclusion, but it may also be developed as argument against that view. That is, contemporary statements of the Consequence Argument may used to attack the type of "incompatibilist" conclusion that most philosophers attribute to it. -/- For the most recent version of this manuscript, plz gmail me: kristin.mickelson.42.

The traditional problem of free will and determinism is ostensibly about settling the relationship between free will and determinism. According to the standard narrative, this problem boils down to settling whether free will stands in a compatibility or incompatibility relation with determinism. Similarly, there is traditional debate over whether a compatibility or an incompatibility relationship holds between free will and indeterminism. Since indeterminism is simply the negation of determinism, anyone who holds that human free will is incompatible with both determinism (...) and indeterminism seems to be committed to free-will impossibilism, i.e. the view that free will is metaphysically impossible. We might summarize this constructive dilemma argument as follows: -/- The Standard Dilemma Argument 1. Necessarily, either determinism or its negation, i.e. indeterminism, is true. 2. Necessarily, determinism is incompatible with free will. 3. Necessarily, indeterminism is incompatible with free will. 4. Therefore, free will is metaphysically impossible; impossibilism is true. -/- In this essay, I argue that the term “incompatible” used in this argument is ambiguous. Since there are two fundamentally different ways to disamabiguate the term “incompatible”, there are at least four substantively different ways to disambiguate the Standard Dilemma Argument. Because these four arguments are typically conflated, the philosophically interesting differences between these four instances of the Standard Dilemma Argument are generally ignored. (shrink)

Joe Campbell has identified an apparent flaw in van Inwagen’s Consequence Argument. It apparently derives a metaphysically necessary conclusion from what Campbell argues is a contingent premise: that the past is in some sense necessary. I criticise Campbell’s examples attempting to show that this is not the case (in the requisite sense) and suggest some directions along which an incompatibilist could reconstruct her argument so as to remain immune to Campbell’s worries.

[ draft, later version under review ] Joe Campbell has identified an apparent flaw in van Inwagen’s Consequence Argument.

In simplified form, the argument that I am defending holds that the incompatibility of our freedom with determinism follows from the conjunction of (1) a plausible supervenience claim which says that whether a human agent is free depends only on what happens during the agent’s life and (2) a freedom-cancellation principle of Richard Gale which says that an agent is not free if all of her actions are intentionally brought about by another agent. Improved versions of (1) and (2) are (...) also considered. (shrink)

It is, as Dana Nelkin (2004) says, a rare point of agreement among participants in the free will debate that rational deliberation presupposes a belief in freedom. Of course, the precise content of that belief – and, indeed, the nature of deliberation – is controversial, with some philosophers claiming that deliberation commits us to a belief in libertarian free will (Taylor 1966; Ginet 1966), and others claiming that, on the contrary, deliberation presupposes nothing more than an epistemic openness that is (...) entirely compatible with determinism (Dennett 1984; Kapitan 1986). Since, however, the claim that deliberation presupposes freedom is accepted by all sides in the free will debate, it ought to be possible to frame a minimal version that is neutral between compatibilism and incompatibilism, and which therefore can be accepted by everyone. Peter van Inwagen has advanced the best-known such claim: ‘all philosophers who have thought about deliberation agree on one point: one cannot deliberate about whether to perform a certain act unless one believes it is possible for one to perform it’ (van Inwagen 1983: 154). It is the purpose of this paper to argue that van Inwagen, and the many philosophers who have followed him in this regard, is wrong. (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.

Manipulation arguments that start from the intuition that manipulated agents are neither free nor morally responsible then conclude to that free will and moral responsibility are incompatible with determinism. The Zygote argument is a special case of Manipulation argument in which the manipulation intervenes at the very conception of the agent. In this paper, I argue that the Zygote argument fails because (i) very few people share the basic intuitions the argument rests on, and (ii) even those who share this (...) intuition do so for reasons that are unrelated to determinism. Rather, I argue that intuitions about the Zygote argument (and Manipulation arguments in general) are driven by people's intuitions about the deep self, as shown by the fact that intuitions about manipulated agents depend on the moral value of the agent's behavior.

Natural compatibilists say that moral responsibility is compatible with natural (or causal) determinism, where natural events and laws of nature determine everything that happens. Theological compatibilists say that moral responsibility is compatible with theological determinism, where God (rather than natural events/laws) determines everything that happens. Some philosophers accept natural compatibilism but reject theological compatibilism, and, in this chapter, I argue that this combination of views is untenable I start with a discussion of why someone might be attracted to this combination (...) of views in the first place, which includes a discussion of the manipulation argument against compatibilism. Some natural compatibilists endorse “soft-line” responses to this argument—responses which imply theological incompatibilism. I argue that such “soft-line” approaches cannot succeed, and along the way I argue that their failure undermines Jason Turner’s recent compatibilist free will defense (in response to the problem of evil). I wrap up by considering some implications of my conclusion that natural compatibilists should be theological compatibilists, including whether my conclusion highlights the “cost” of compatibilism, as proponents of manipulation arguments sometimes allege, and also whether anything follows with regard to God’s standing to blame determined human agents.

Determinism is frequently understood as implying the possibility of perfect prediction. This possibility then functions as an assumption in the Manipulation Argument for the incompatibility of free will and determinism. Yet this assumption is mistaken. As a result, arguments that rely on it fail to show that determinism would rule out human free will. We explain why determinism does not imply the possibility of perfect prediction in any world with laws of nature like ours, since it would be impossible for (...) an agent to predict with certainty any future event that is causally influenced by events outside her own backward light cone yet inside the backward light cone of the future event. This is the light-cone limit and it undermines the Manipulation Argument or limits what this argument can tell us about the relevance of determinism to free will. We also respond to objections that the light-cone limit is irrelevant to the Manipulation Argument. (shrink)

Since the rise of the theory of determinism, philosophers have argued and declared that we are diminished by it. Bishop Bramhall against Thomas Hobbes in the 17th Century, Kant against Hume in the 18th, F. H. Bradley against John Stuart Mill in the 19th, Robert Kane and Robert Nozick against such as me in the 20th Century. There must be something in this relentless tradition. It cannot, it seems to me, be the falsehood of determinism. Is it, so to speak, (...) a larger fact than either determinism or free will? Is it consciousness? The new paper below, a draft to be thought more about for the 2nd edition of Kane's summative Oxford Handbook of Free Will, comes to that conclusion by way of a look at the principal parts of the problem of determinism, one being what is called probabilistic causation.

Many suppose some form of free will is required to make moral responsibility possible. Levinas thinks this is backwards. Freedom does not make moral responsibility possible. Moral responsibility makes freedom possible. Free will is not a condition for morality. Free will is an aspect and expression of our moral condition. Key to Levinas’s argument is his rejection of free-will-individualism: the idea that free will is a power a single being could possess. A “contradiction” extracted from standard accounts, and related troubles (...) with autonomy as found in Kant and Korsgaard, motivate Levinas’s counter-claim: Freedom cannot be by nature mine. For my own nature is something I am free to change. Hence my own nature is something from which I am somehow free. Traditional freedom over one’s self thus presupposes a prior liberating ‘inner distance’ from one’s self. And this initial detachment or un-self-centering is an ethical distancing which only another person can effect. Free will individualism is mistaken, because other persons play an indispensable role in making us free. The chapter concludes that free will is best thought of as Levinas suggests: not as an individual power, but as a social process like love: an ongoing second-personal responsiveness wherein we face and free one another.

Any person truly considering belief in a scientific world view has to confront the question of whether and in what sense, if she views herself as a natural system in a world governed by natural laws, she can continue to regard herself as free. The prima facie clash is usually expressed in terms of a conflict between freedom and determinism, captured in an argument known as the Consequence Argument. If the natural laws are deterministic, our behavior must be deducible by (...) them from the initial conditions of the universe, and we are wrong to think that we exercise regulative control over action. The most common tactic for those who defend the compatibility of freedom and determinism is to deny that regulative control is a requirement of freedom. I will argue that, whether or not regulative control is a requirement of freedom, it is – surprisingly! - compatible with determinism. The discussion here replays themes of the first essay. Personal freedom is a complex concept, embedded in a tangle of criss-crossing personal, social, theological, psychological, and metaphysical debates, each placing its own requirement on the concept, and I make no attempt to address the general question of whether we are free. It is only the specific challenge presented by the Consequence Argument that I address, and that challenge is a clearly defined dynamical issue about the possibility of regulative control over action in a world governed by deterministic laws.

One debate surrounding Derk Pereboom’s (2001, 2014) four-case argument against compatibilism focuses on whether, and why, we judge manipulated agents to be neither free nor morally responsible. In this paper, we propose a novel explanation. The four-case argument features cases where an agent is the only individual in her universe who has been manipulated. Let us call manipulation whose scope includes at least one but not all agents existential manipulation. Contrast this with universal manipulation, which affects all agents within a (...) universe. We propose that we find agents in Pereboom’s manipulation cases less free and morally responsible in part because they are the target of existential manipulation. We empirically tested this hypothesis and found that people’s free will and moral responsibility judgments were sensitive to the scope of manipulation: people judged existentially manipulated agents significantly less free and responsible than universally manipulated agents.

The terms ‘compatibilism’ and ‘incompatibilism’ were introduced in the mid-20th century to name conflicting views about the in-principle relationship between the thesis of determinism and the thesis that someone has free will. These technical terms were originally introduced within a specific research paradigm, the classical analytic paradigm, but few free-will theorists still work within that paradigm (i.e. using its methods, granting its substantive background assumptions, etc.). This chapter discusses how the ambiguity of the terms ‘incompatibilism’ and ‘compatibilism’ took root. I (...) also explain why the ambiguity of these anachronistic terms, though relatively innocuous when they were first introduced, is now keeping us from clearly identifying the major positions and battle lines in the contemporary free-will debate. -/- For a copy of the penultimate draft, please gmail me at: kristin.mickelson.42.

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)

Is moral responsibility compatible with determinism? Peter Strawson’s first answer is: I do not know what the thesis of determinism is. His second answer seems to be: Yes, it is, and we can see this by looking to relevant pockets of our ordinary practices and attitudes, especially our responses (resentment, anger, love, forgiveness) to quality of will. His second answer has shaped subsequent discussions of moral responsibility. But what exactly is Strawson’s compatibilism? And is it a plausible view? By attending (...) to Strawson’s account of parenting and the development of moral agents from children to adults, I’ll clarify and defend the following account: For Strawson, the appropriateness conditions for holding responsible change by degrees, over time, based on an agent’s susceptibility to empathy and quality of will, and this shows us that determinism is irrelevant to responsibility.

In this article, I focus on internal dimensions of moral responsibility. I argue that if such dimensions are real -- and it seems they are -- then moral responsibility is compatible with determinism.

The concept of free will is fraught with controversy, as readers of this volume likely know. Philosophers disagree about what free will is, whether we have it, what mitigates or destroys it, and what it's good for. Indeed, philosophers even disagree about how to fix the referent of the term 'free will' for purposes of describing and exploring these disagreements. What one person considers a reasonably neutral working definition of 'free will' is often considered question-begging or otherwise misguided by another. (...) Such disputes make it difficult to summarize the problem of free will, roughly the debate over the nature and existence of free will, in a clear and uncontentious way. In generic terms, however, the two basic solutions to the problem of free will are free-willism, the view that we have free will, and free-will denialism, i.e. the view that we do not have free will. As stated here, neither denialism nor free-willism constitutes a complete solution to the problem of free will; to be complete, a proposed solution must also tell us a convincing story about what free will is and that, as it turns out, is a very difficult task indeed. One historically popular way of approaching the problem of free will is to ask about the relationship between free will and determinism: "Does free will stand in relation R to determinism: yes or no?" This is just a template for a question, of course. To transform this template-question into a substantive question with a clear meaning, we need to flesh out the template's free-will relatum, its determinism relatum, and give a precise value to relation R. There is, however, no uncontroversial way to do this. In addition to the standard difficulties raised by fixing the referent of 'free will', philosophers hold radically different views about what is-or should be-meant by 'determinism', Shabo ), and they identify relations which are as substantively different as correlation and causation when characterizing relation R. In practical terms, then, it may be best to think of the problem of determinism as a loose collection of disagreements about how to best spell out and answer the template-question, and how asking and answering such questions would help us to solve the problem of free will.

The direct argument is among the most prominent arguments for the incompatibility of determinism and moral responsibility. Some critics of the argument have accused it, or certain defenses of its central premise, of begging the question. This article responds to that accusation.

Précis of Rejecting Retributivism: Free Will, Punishment, and Criminal Justice (2022).

This Element examines the concept of moral responsibility as it is used in contemporary philosophical debates and explores the justifiability of the moral practices associated with it, including moral praise/blame, retributive punishment, and the reactive attitudes of resentment and indignation. After identifying and discussing several different varieties of responsibility-including causal responsibility, take-charge responsibility, role responsibility, liability responsibility, and the kinds of responsibility associated with attributability, answerability, and accountability-it distinguishes between basic and non-basic desert conceptions of moral responsibility and considers a (...) number of skeptical arguments against each. It then outlines an alternative forward-looking account of moral responsibility grounded in non-desert-invoking desiderata such as protection, reconciliation, and moral formation. It concludes by addressing concerns about the practical implications of skepticism about desert-based moral responsibility and explains how optimistic skeptics can preserve most of what we care about when it comes to our interpersonal relationships, morality, and meaning in life.

Molinists hold that there are contingently true counterfactuals about what agents would do if put in specific circumstances, that God knows these prior to creation, and that God uses this knowledge in choosing how to create. In this essay we critique Molinism, arguing that if these theses were true, agents would not be free. Consider Eve’s sinning upon being tempted by a serpent. We argue that if Molinism is true, then there is some set of facts that fully explains both (...) Eve’s action and everything else Eve does that influences that action; and that if this is the case, Eve does not act freely. The first premise of this argument follows from the explanatory relations the Molinist is committed to, and the second premise follows from libertarian intuitions about free will. (shrink)

Like most episodes of Black Mirror, “Hang the DJ” raises a host of philosophical questions. While there is much from this episode to explore, this chapter will explore something that has not yet been addressed in other work, namely the connection between “Hang the DJ” and questions about free will and determinism (or indeterminism, as the case may be). This chapter will proceed as follows: first, I will sketch some reasons for thinking that, if determinism is true, then no one (...) has or exercises free will. One type of response to determinism’s threat to free will is to accept the incompatibility of free will and determinism and to maintain that we nevertheless have free will. Theorists who endorse indeterministic accounts of free will are called libertarians in the free will debate (but please do not confuse them with political libertarians). Second, I will explain a bit more of the mechanics of libertarianism. Third, I will discuss an influential challenge to libertarianism that has come to be known as the “rollback argument.” The mechanics of this challenge will resemble the plot twist of “Hang the DJ.” Fourth, and finally, I will explore the episode’s portrayal of the value of undetermined choice.

P. van Inwagen famously offered three precise versions of the so-called Consequence Argument for incompatibilism. The third of these essentially employs the notion of an agent’s having a choice with respect to a proposition. In this paper, I offer two intuitively attractive accounts of this notion in terms of the explanatory connective ‘because’ and explore the prospects of the third argument once they are in play. Under either account, the argument fails.

This paper argues that Frankfurt-style counterexamples (FSCs) do not compromise the agent’s ability to decide otherwise. In his attack on the Principle of Alternative Possibilities, Frankfurt relied on what Austin called the ‘all-in’ sense of ‘can’, and misconstrued the agent’s inability to do otherwise as an all-in can’t. Like the new dispositionalists, I maintain that the agent’s relevant abilities are ‘masked’ rather than lost in Frankfurt cases. The argument from masked abilities, however, is not confined to a compatibilist construal of (...) the relevant abilities. On a libertarian construal, Black deprives Jones of the opportunity to use his two-way power of choice to a different outcome than he actually uses it. I argue that being deprived of this opportunity is immaterial to what free will requires. In the second half of the paper, I relate my approach to the ‘flicker of freedom’ strategy. On closer look, we do find a residual ability that Jones not only possesses but also exercises in cases where Black intervenes. I argue that Jones tries to decide otherwise in these cases, that Black only thwarts the success of Jones’s attempt, and that being snatched from the wheel at the very last moment does not compromise Jones’s free will. (shrink)

This essay is an investigation into the sense of ‘able’ relevant to free will, where free will is understood as requiring the ability to do otherwise. I argue that van Inwagen's recent functional specification of the relevant sense of ‘able’ is flawed, and that explicating the powers involved in free will shall likely require paying detailed attention to the semantics and pragmatics of ‘can’ and ‘able’. Further, I argue that van Inwagen's promise-level ability requirement on free will is too strong. (...) I also argue that Mele's conjecture that the strength of the ability to perform the ‘alternative’ action be no higher than the strength of the ability exercised in performing an action is mistaken. I suggest there is an asymmetry in the strengths of the abilities which make up the n-way power that comprises free will, and that this looks to have some interesting consequences for the connection between the abilities required for free will and, e.g. the ‘up to us’ locution.

The goal of this thesis is to analyse the notion of free will from the perspectives of various stances in the philosophy of mind. It employs an approach quite different than the more standard one, in which philosophers try to answer the question “do we have free will?” directly. The first chapter of this thesis contains an analysis of the compatibilism/incompatibilism debate – the question “is free will compatible with the determinism?” Showing that the answer to this question means something (...) different for compatibilists and incompatibilists and the fact that it also depends on assumptions about the mind that a researcher has, provides a rationale for the approach chosen in this thesis. The subsequent chapters contain discussions about the relation between free will and dualism, materialism and transcendental idealism. The considerations about free will in dualistic stances serve as a background for the two final chapters, which contain the most important conclusions of the thesis. In the third chapter I discuss the relation between free will and materialism with a focus on whether it is sensible to talk about free will in the context of eliminative materialism. To do that, I go more in depth into the analysis of how artificial neural networks process information. In the last chapter, devoted to transcendental idealism, I present a solution to the free will problem that incorporates eliminative materialism on the empirical level. (shrink)

Many manipulation arguments against compatibilism rely on the claim that manipulation is relevantly similar to determinism. But we argue that manipulation is nothing like determinism in one relevant respect. Determinism is a "universal" phenomenon: its scope includes every feature of the universe. But manipulation arguments feature cases where an agent is the only manipulated individual in her universe. Call manipulation whose scope includes at least one but not all agents "existential manipulation." Our responsibility practices are impacted in different ways by (...) universal and existential phenomena. And this is a relevant difference, especially on Strawsonian approaches to moral responsibility, which take facts about our responsibility practices to be deeply connected to the nature of responsibility itself. We argue that Strawsonian accounts of moral responsibility are immune to manipulation arguments, and no attempt to modify the scope of manipulation or determinism featured in these arguments will help incompatibilists secure their desired conclusion.

In “Causality and Determination”, Anscombe stressed that, in her view, physical determinism and free action were incompatible. As the relevant passage suggests, her espousal of incompatibilism was not merely due to specific features of human ‘ethical’ freedom, but due to general features of agency, intentionality, and voluntariness. For Anscombe went on to tentatively suggest that lack of physical determination was required for the intentional conduct of animals we would not classify as ‚free‘, too. In this paper, I examine three different (...) lines of argument to establish Anscombe’s latter suggestion, which are based on general considerations about the causal efficacy of psychological-agential phenomena, the nature of agency, and the specific features of intentional agency. I start with Anscombe’s own claim from “The Causation of Action” that microphysical determinism would make psychological and personal phenomena epiphenomenal, before I turn to the view of ‘Agency Incompatibilism’, that genuine agency requires the absence of antecedent necessitation, and, lastly, to concerns about some crucial features of intentional agency which we find in both human and animal agents.

Libertarian free will is, roughly, the view that agents cause actions to occur or not occur: Maddy’s decision to get a beer causes her to get up off her comfortable couch to get a beer, though she almost chose not to get up. Libertarian free will notoriously faces the luck objection, according to which agential states do not determine whether an action occurs or not, so it is beyond the control of the agent, hence lucky, whether an action occurs or (...) not: Maddy’s reasons for getting beer in equipoise with her reasons to remain in her comfortable seat do not determine that she will get up or stay seated, so it seems beyond her control, hence lucky, that she gets up. In this paper I consider a sub-set of the luck objection called the Physical Indeterminism Luck Objection, according to which indeterministic physical processes cause actions to occur or not, and agent’s lack control over these indeterministic physical processes, so agent’s lack control over, hence it is lucky, whether action occurs or not. After motivating the physical indeterminism luck objection, I consider responses from three recent event-causal libertarian models, and conclude that they fail to overcome the problem, though one promising avenue is opened up.

Although philosophers sympathetic to Peter Strawson's view in “Freedom and Resentment” tend to be compatibilists, they need not be. This paper develops a recent suggestion that Strawson's view can be read as consistent with libertarianism by showing that an important distinction Strawson makes between personal and moral reactive attitudes leaves room to be a Strawsonian compatibilist with respect to personal responsibility and a Strawsonian incompatibilist with respect to moral responsibility. Understanding this possibility reveals a potential gap within Strawson's argument that (...) should be of interest to both Strawsonians and their critics. (shrink)

Anscombe’s “Causality and Determination” is often cited in the contemporary free will debate, but rarely discussed in much detail. It’s main contribution, it is thought, is the defense of an alternative to deterministic causation, thus clearing the way for an incompatibilist analysis of free actions in terms of probabilistic causation. However, in this paper I will show that the contemporary probabilistic analysis of free action actually stands in direct conflict with Anscombe’s lecture. Instead, I will argue, its true value for (...) incompatibilist accounts of free will lies in Anscombe’s thought that there are various fundamentally different kinds of causality. This variety, I argue, allows for a revised conception indeterminism and an understanding of free will as the manifestation of a particular sort of agent-causal power. (shrink)

The consensus is that in his 1755 Nova Dilucidatio, Kant endorsed broadly Leibnizian compatibilism, then switched to a strongly incompatibilist position in the early 1760s. I argue for an alternative, incompatibilist reading of the Nova Dilucidatio. On this reading, actions are partly grounded in indeterministic acts of volition, and partly in prior conative or cognitive motivations. Actions resulting from volitions are determined by volitions, but volitions themselves are not fully determined. This move, which was standard in medieval treatments of free (...) choice, explains why Kant is so critical of Crusius’s version of libertarian freedom: Kant understands Crusius as making actions entirely random. In defense of this reading, I offer a new analysis of the version of the principle of sufficient reason that appears in the Nova Dilucidatio. This principle can be read as merely guaranteeing grounds for the existence of things or substances, rather than efficient causes for states and events. As such, the principle need not exclude libertarian freedom. Along the way, I seek to illuminate obscure aspects of Kant’s 1755 views on moral psychology, action theory, and the threat of theological determinism. (shrink)

Some incompatibilists about free will or moral responsibility and determinism would abandon their incompatibilism were they to learn that determinism is true. But is it reasonable to flip-flop in this way? In this article, we contend that it is and show what follows. The result is both a defense of a particular incompatibilist strategy and a general framework for assessing other cases of flip-flopping.

Given the available evidence, I argue that we face considerable uncertainty about free will. In particular, I argue that the available philosophical evidence does not support being highly confident in our theories about the nature of free will, though this does not necessarily mean that we should suspend judgment about either incompatibilism or compatibilism. For those who accept incompatibilism, however, I argue that there is enough uncertainty about libertarian free will that they should suspend judgment about whether we are ever (...) free, if not reject free will entirely. While I do not claim that compatibilists should be similarly agnostic about the existence of free will, I argue that most compatibilist theories are subject to considerable uncertainty as well, so that most compatibilists should be agnostic about how often we act freely. I conclude with a brief discussion of how we might address these issues going forward. (shrink)

This essay reframes salient issues in discussions of free will using conceptual apparatus developed in the works of Saul Kripke, with particular attention paid to his little-discussed technical notion of a prejudice. I begin by focusing on how various forms of modality (metaphysical, epistemic, and conceptual) underlie alternate forms of compatibilism and discuss why it is important to avoid conflating these forms of compatibilism. The concept of a prejudice is then introduced. We consider the semantic role of prejudices, in particular (...) conditions in which prejudices turn out to express metaphysically necessary truths. With that as background, I discuss a set of prejudices involving the notion of choice. We consider the role these prejudices might play, should they turn out to be true, in determining the answer to various compatibility questions concerning the nature of moral responsibility and choice.

This paper aims to defend deliberation-compatibilism against several objections, including a recent counterexample by Yishai Cohen that involves a deliberator who believes that whichever action she performs will be the result of deterministic manipulation. It begins by offering a Moorean-style proof of deliberation-compatibilism. It then turns to the leading argument for deliberation-incompatibilism, which is based on the presumed incompatibility of causal determinism and the ‘openness’ required for rational deliberation. The paper explains why this argument fails and develops a coherent account (...) of how one can rationally deliberate and believe in causal determinism without inconsistency. The second half of the paper then takes up Cohen's proposed counterexample and his Four-Case Deliberation Argument against deliberation-compatibilism, which is meant to mirror Derk Pereboom's famous Four-Case Manipulation Argument. In response, the author defends a hard-line reply to FCDA but also argues that the notion of ‘sourcehood’ relevant to rational deliberation differs from that involved in free will. (shrink)

Some thinkers argue that our best scientific theories about the world prove that free will is an illusion. Others disagree. The concept of free will is profoundly important to our self-understanding, our interpersonal relationships, and our moral and legal practices. If it turns out that no one is ever free and morally responsible, what would that mean for society, morality, meaning, and the law? Just Deserts brings together two philosophers – Daniel C. Dennett and Gregg D. Caruso – to debate (...) their respective views on free will, moral responsibility, and legal punishment. In three extended conversations, Dennett and Caruso present their arguments for and against the existence of free will and debate their implications. Dennett argues that the kind of free will required for moral responsibility is compatible with determinism – for him, self-control is key; we are not responsible for becoming responsible, but are responsible for staying responsible, for keeping would-be puppeteers at bay. Caruso takes the opposite view, arguing that who we are and what we do is ultimately the result of factors beyond our control, and because of this we are never morally responsible for our actions in the sense that would make us truly deserving of blame and praise, punishment and reward. These two leading thinkers introduce the concepts central to the debate about free will and moral responsibility by way of an entertaining, rigorous and sometimes heated philosophical dialogue. What emerges is a clear account of the latest thinking on free will, and what is at stake for our moral and legal practices. (shrink)

Capacity of conscious agents to perform genuine choices among future alternatives is a prerequisite for moral responsibility. Determinism that pervades classical physics, however, forbids free will, undermines the foundations of ethics, and precludes meaningful quantification of personal biases. To resolve that impasse, we utilize the characteristic indeterminism of quantum physics and derive a quantitative measure for the amount of free will manifested by the brain cortical network. The interaction between the central nervous system and the surrounding environment is shown to (...) perform a quantum measurement upon the neural constituents, which actualize a single measurement outcome selected from the resulting quantum probability distribution. Inherent biases in the quantum propensities for alternative physical outcomes provide varying amounts of free will, which can be quantified with the expected information gain from learning the actual course of action chosen by the nervous system. For example, neuronal electric spikes evoke deterministic synaptic vesicle release in the synapses of sensory or somatomotor pathways, with no free will manifested. In cortical synapses, however, vesicle release is triggered indeterministically with probability of 0.35 per spike. This grants the brain cortex, with its over 100 trillion synapses, an amount of free will exceeding 96 terabytes per second. Although reliable deterministic transmission of sensory or somatomotor information ensures robust adaptation of animals to their physical environment, unpredictability of behavioral responses initiated by decisions made by the brain cortex is evolutionary advantageous for avoiding predators. Thus, free will may have a survival value and could be optimized through natural selection. (shrink)

Obligation incompatibilism is the view that determinism precludes moral obligation. I argue for the following. Two principles, ‘ought’ implies ‘can’ and ‘ought not’ is equivalent to ‘impermissi...
