Summary and brief critical evaluation of 4 views on free will (Kane, Fischer, Pereboom, Vargas).

Four Views on Free Will is a robust and careful debate about free will, how it interacts with determinism and indeterminism, and whether we have it or not. Providing the most up-to-date account of four major positions in the free will debate, the second edition of this classic text presents the opposing perspectives of renowned philosophers John Martin Fischer, Robert Kane, Derk Pereboom, and Manuel Vargas. -/- Substantially revised throughout, this new volume contains eight in-depth chapters, (...) almost entirely rewritten for the new edition, in which the authors state their different positions on the debate, offer insights into how their views have evolved over the past fifteen years, respond to recent critical literature in the field, and interact and engage with each other in dialogue. In the first four chapters the authors defend their distinctive views about free will: libertarianism, compatibilism, hard incompatibilism, and revisionism. The subsequent four chapters consist of direct replies by each of the authors to the other three. (shrink)

Exploring the Illusion of Free Will and Moral Responsibility is an edited collection of new essays by an internationally recognized line-up of contributors. It is aimed at readers who wish to explore the philosophical and scientific arguments for free will skepticism and their implications.

This article sets out a forward-looking account of moral responsibility on which the ground-level practice is directly sensitive to aims such as moral formation and reconciliation, and is not subject to a barrier between tiers. On the contrasting two-tier accounts defended by Daniel Dennett and Manuel Vargas, the ground-level practice features backward-looking, desert-invoking justifications that are in turn justified by forward-looking considerations at the higher tier. The concern raised for the two-tier view is that the ground-level practice will (...) be insufficiently responsive to the forward-looking aims that are held to justify it. On the single-tier alternative, forward-looking considerations can more readily motivate substantial revisions, which the practice, due to serious and pervasive deficiencies, requires. (shrink)

In this article I develop several responses to my co-authors of Four Views on Free Will. In reply to Manuel Vargas, I suggest a way to clarify his claim that our concepts of free will and moral responsibility should be revised, and I question whether he really proposes to revise the notion of basic desert at stake in the debate. In response to Robert Kane, I examine the role the rejection of Frankfurt-style arguments has in his position, and (...) whether his criticism of my version of this argument is sound. In reply to John Fischer, I argue that the reasons-responsiveness central to his account of moral responsibility is not best characterized counterfactually, and I provide a suggestion for revision.

This article summarizes the moderate revisionist position I put forth in Four Views on Free Will and responds to objections to it from Robert Kane, John Martin Fischer, Derk Pereboom, and Michael McKenna. Among the principle topics of the article are (1) motivations for revisionism, what it is, and how it is different from compatibilism and hard incompatibilism, (2) an objection to the distinctiveness of semicompatibilism against conventional forms of compatibilism, and (3) whether moderate revisionism is committed to (...) realism about moral responsibility.

In this paper I offer from a source compatibilist's perspective a critical discussion of "Four Views on Free Will" by John Martin Fischer, Robert Kane, Derk Pereboom, and Manuel Vargas. Sharing Fischer's semi-compatibilist view, I propose modifications to his arguments while resisting his coauthors' objections. I argue against Kane that he should give up the requirement that a free and morally responsible agent be able to do otherwise (in relevant cases). I argue against Pereboom that (...) his famed manipulation argument be resisted by contending that the agents in it are free and responsible. And I also argue against Vargas by challenging the sense in which his revisionist thesis differs from a position like Fischer's and mine. I close by reflecting on the nature of desert. All seem to assume it is central to the debate, but what is it? (shrink)

I have argued we are not free in the sense required for moral responsibility, while at the same time a conception of life without this type of free will would not be devastating to morality or to our sense of meaning in life, and in certain respects it may even be beneficial (cf. Pereboom 2001). In ..

1. Consider first Baker’s definition of constitution. In her view, constitution is a relation between concrete individuals. Each concrete individual is fundamentally a member of exactly one primary kind. By definition, any concrete individual has its primary kind membership essentially, so that a concrete individual x’s ceasing to be a member of this kind entails that x ceases to exist. For example, David’s primary kind is statue, Piece’s primary kind is piece of marble. Suppose that x and y are concrete (...) individuals; F* designates the property of having F as one’s primary-kind; F and G are not the same kind; individual x has F* and individual y has G*; and D designates G- favorable circumstances—“the milieu required for something to be a G”.

Esta investigación pretende reanudar la indagación sobre el sentido. Es predominantemente teórica y cualitativa. Su objetivo, describir el fenómeno referido mediante el sentido, a partir de la usanza comunicativa. Con base en lo cual se ha querido explicar la relación que existe entre sentido y comunicación. Metodológicamente analizó la doctrina mediante lo que Peirce denominó método retroductivo, es decir, buscando la estructura lógica de sus postulados. También analizó algunos actos de habla en que se emplea la expresión sentido, y lo (...) confrontó con la doctrina sobre el sentido. El resultado es que fue definido mediante sinónimos sin un fundamento satisfactorio. Mientras que a partir del uso del sentido puede empezar a plantearse que tiene relación con la experiencia de los hablantes que los predispone a actuar de una cierta forma. Como conclusión, la comunicación es el mecanismo mediante el cual los hablantes circulan su sentido y, es mediante ella que se hace posible un cierto tipo de acción social e individual. (shrink)

connection to the action, or alternately, the idea that an agent must be in some sense responsive to reasons.1 Indeed, we might even understand much of the past couple of decades of philosophical work on moral responsibility as concerned with investigating which of these two approaches offers the most viable account of moral responsibility. Here, I wish to revisit an idea basic to all of this work. That is, I consider whether there is even a fundamental distinction between these approaches. (...) I will argue that the relationship between these two approaches to moral responsibility is much more complicated than is ordinarily assumed. I shall argue that there are reasons to think that one of these views may ultimately collapse into the other, and if not, that there is nevertheless reason to think one of these views has misidentified the features of agency relevant to moral responsibility. The view that follows is one that we might call the primacy of reasons. In the second half of the article I consider whether recent experimental work speaks in favor of the alternative to the primacy of reasons. Its proponents argue that it does. I argue that it does not. (shrink)

One reason that many of the philosophical debates about free will might seem intractable is that di erent participants in those debates use various terms in ways that not only don't line up, but might even contradict each other. For instance, it is widely accepted to understand libertarianism as\the conjunction of incompatibilism [the thesis that free will is incompatible with the truth of determinism] and the thesis that we have free will" (van Inwagen (1983), 13f; see also Kane (2001), 17; (...) Pereboom (2006), xiv). However, for van Inwagen's later reservations about the use of the term `libertarianism', see van Inwagen (2008), relevant pages). This makes perplexing a number of views that have the name `libertarian compatibilism' (see Vihvelin (2000) and Arvan (2013)) as on the standard use of the terms involved, the name appears to involve a contradiction. Even the meaning and usage of the term `free will' is itself contested. Manuel Vargas writes that \`free will' is a term of both ordinary and technical discourse" (Vargas (2013), 325). However, it is not clear if the ordinary use of the term always tracks the technical use. But in an in uential paper on \How to Think about About the Problem of Free Will," Peter van Inwagen claims that \the phrase `free will' . . . hardly exists except as a philosophical term of art. Its non- philosophical uses are pretty much con ned to the phrase `of his/her own free will' which means `uncoerced"' (van Inwagen (2008), 320 footnote 1). To many of us, a look at the philosophical and literatures of the past millennium suggest a use that need not be a technical notion, even if it is often used in a technical way. No matter how this debate about the `ordinary use' of the phrase turns out, recognizing that `free will' gets used in di erent ways and being careful in such usage is important in order to avoid what Chalmers has called `merely verbal disputes' (Chalmers (2011)). For this reason, we want to be very clear in how we understand and de ne free will. There seem to be at least two di erent fundamental notions of what free will is in the contemporary literature. The rst of these, which seems to have garnered the most attention in the last century, works under the assumption that for a person to rightly be said to have free will, she must have the ability 1 to do otherwise than what she does, in fact, do. Under this view I could be said to have freely chosen to drive to work only if I also could have freely chosen, for example, to bike to work or to skip work altogether. This approach to free will is referred to as a `leeway-based approach' (cite my book) or an `alternative- possiblities approach' (see Sartorio (2016).) In contrast, a smaller percentage of the extant literature focuses primarily on the issues of `source,' `ultimacy,' and `origination'. This second approach doesn't focus immediately on the presence or absence of alternative possibilities. On this approach, I freely choose to drive to work only if I am the source of my choice and there is nothing outside of me from which the choice is ultimately derived. In what follows, we refer to the rst of these conceptions|the conception that free will is primarily a matter of having alternative possibilities|as the `leeway- based' conception. Similarly, we will refer to the second of these conceptions| that free will is primarily a matter of our being the source of our choices in a particular way|as the `sourcehood' conception. (John Fischer and Carolina Sartorio refers to sourcehood views as `actual sequence' views; see Fischer (2006) and Sartorio (2016)). Both of these notions can be seen in the following passage taken from Robert Kane: We believe we have free will when we view ourselves as agents ca- pable of in uencing the world in various ways. Open alternatives, or alternative possibilities, seem to lie before us. We reason and deliberate among them and choose. We feel (1) it is `up to us' what we choose and how we act; and this means we could have chosen or acted otherwise. As Aristotle noted: when acting is `up to us,' so is not acting. This `up-to-us-ness' also suggests (2) the ultimate control of our actions lies in us and not outside us in factors beyond our control (Kane (2005), 6). In the next two sections, I look in greater detail at each of these two approaches to the nature of free will, and how they each seek to approach what it means for an action to be `up to us'. I also show how the di erences between these two conceptions cut across the debate about what Kane refers to as the Com- patibility Question: \Is free will compatible with determinism?" (Kane (1996), 13). Along the way, I also brie y point out a number of ways how which of these conceptions is at work shapes how one engages various arguments and other issues regarding. (shrink)

Manuel Vargas advocates a revised understanding of the terms “free will” and “moral responsibility” that eliminates the problematic libertarian commitments inherent to the commonsense understanding of these terms. I argue that in order to make a plausible case for why philosophers ought to adopt his recommendations, Vargas must explain why we ought to retain the retributivist elements that figure prominently in both commonsense views about morality and philosophical discussions concerning free will and moral responsibility. Furthermore, I argue (...) that his revisionist account lacks the resources necessary to accommodate retributivist attitudes and practices. (shrink)

Most people assume that, even though some degenerative or criminal behavior may be caused by influences beyond our control, ordinary human actions are not similarly generated, but rather are freely chosen, and we can be praiseworthy or blameworthy for them. A less popular and more radical claim is that factors beyond our control produce all of the actions we perform. It is this hard determinist stance that Derk Pereboom articulates in Living Without Free Will. Pereboom argues that (...) our best scientific theories have the consequence that factors beyond our control produce all of the actions we perform, and that because of this, we are not morally responsible for any of them. He seeks to defend the view that morality, meaning and value remain intact even if we are not morally responsible, and furthermore, that adopting this perspective would provide significant benefit for our lives.

In this book, Derk Pereboom explores how physicalism might best be formulated and defended against the best anti-physicalist arguments. Two responses to the knowledge and conceivability arguments are set out and developed. The first exploits the open possibility that introspective representations fail to represent mental properties as they are in themselves; specifically, that introspection represents phenomenal properties as having certain characteristic qualitative natures, which these properties might actually lack. The second response draws on the proposal that currently unknown (...) fundamental intrinsic properties provide categorical bases for known physical properties and would also yield an account of consciousness. While there are non-physicalist versions of this position, some are amenable to physicalism. The book's third theme is a defense of a nonreductive account of physicalism. The type of nonreductivism endorsed departs from others in that it rejects all token identity claims for psychological and microphysical entities. The deepest relation between the mental and the microphysical is constitution, where this relation is not to be explicated by the notion of identity. (shrink)

This paper features Derk Pereboom’s replies to commentaries by Victor Tadros and Saul Smilansky on his non-retributive, incapacitation-focused proposal for treatment of dangerous criminals; by Michael McKenna on his manipulation argument against compatibilism about basic desert and causal determination; and by Alfred R. Mele on his disappearing agent argument against event-causal libertarianism.

Moral psychology is the study of how human minds make and are made by human morality. This state of the art volume covers contemporary philosophical and psychological work on moral psychology, as well as notable historical theories and figures in the field of moral psychology, such as Aristotle, Kant, Nietzsche, and the Buddha. The volume’s 50 chapters, authored by leading figures in the field, cover foundational topics, such as character, virtue, emotion, moral responsibility, the neuroscience of morality, weakness of will, (...) and the nature of moral judgments and reasons. The volume also canvases emerging work in applied moral psychology, including adaptive preferences, animals, mental illness, poverty, marriage, race, bias, and victim blaming. (shrink)

Wrongdoing and the Moral Emotions provides an account of how we might effectively address wrongdoing given challenges to the legitimacy of anger and retribution that arise from ethical considerations and from concerns about free will. The issue is introduced in Chapter 1. Chapter 2 asks how we might conceive of blame without retribution, and proposes an account of blame as moral protest, whose function is to secure forward-looking goals such as the moral reform of the wrongdoer and reconciliation in relationships. (...) Chapter 3 considers whether it's possible to justify effectively dealing those who pose dangerous threats if they do not deserve to be harmed, and contends that wrongfully posing a threat is the core condition for the legitimacy of defensive harming. Chapter 4 provides an account of how to treat criminals without a retributive justification for punishment, and argues for an account in which the right of self-defense provides justification for measures such as preventative detention. Chapter 5 considers how we might forgive if wrongdoers don't basically deserve the pain of being resented, which forgiveness would then renounce, and proposes that forgiveness be conceived instead as renunciation of the stance of moral protest. Chapter 6 considers how personal relationships might function without retributive anger having a role in responding to wrongdoing, and contends that the stance of moral protest, supplemented with non-retributive emotions, is sufficient. Chapter 7 surveys the options for theistic and atheistic attitudes regarding the fate of humanity in a deterministic universe, and defends an impartial hope for humanity. (shrink)

Neil Levy (2007) argues that empirical data shows that psychopaths lack the moral knowledge required for moral responsibility. His account is intriguing, and it offers a promising way to think about the significance of psychopaths for work on moral responsibility. In what follows we focus on three lines of concern connected to Levy's account: his interpretation of the data, the scope of exculpation, and the significance of biological explanations for anti-social behavior.

As philosophical and scientific arguments for free will skepticism continue to gain traction, we are likely to see a fundamental shift in the way people think about free will and moral responsibility. Such shifts raise important practical and existential concerns: What if we came to disbelieve in free will? What would this mean for our interpersonal relationships, society, morality, meaning, and the law? What would it do to our standing as human beings? Would it cause nihilism and despair as some (...) maintain or would it rather have a humanizing effect on our practices and policies, freeing us from the negative effects of belief in free will? In this chapter we consider the practical implications of free will skepticism and argue that life without free will and basic desert moral responsibility would not be as destructive as many people believe. We argue that prospects of finding meaning in life or of sustaining good interpersonal relationships, for example, would not be threatened. On treatment of criminals, we argue that although retributivism and severe punishment, such as the death penalty, would be ruled out, preventive detention and rehabilitation programs would still be justified. While we will touch on all these issues below, our focus will be primarily on this last issue. -/- We begin in section I by considering two different routes to free will skepticism. The first denies the causal efficacy of the types of willing required for free will and receives its contemporary impetus from pioneering work in neuroscience by Benjamin Libet, Daniel Wegner, and John-Dylan Haynes. The second, which is more common in the philosophical literature, does not deny the causal efficacy of the will but instead claims that whether this causal efficacy is deterministic or indeterministic, it does not achieve the level of control to count as free will by the standards of the historical debate. We argue that while there are compelling objections to the first route—e.g., Al Mele (2009), Eddy Nahmias (2002, 2011), and Neil Levy (2005)—the second route to free will skepticism remains intact. In section II we argue that free will skepticism allows for a workable morality, and, rather than negatively impacting our personal relationships and meaning in life, may well improve our well-being and our relationships to others since it would tend to eradicate an often destructive form of moral anger. In section III we argue that free will skepticism allows for adequate ways of responding to criminal behavior—in particular, incapacitation, rehabilitation, and alternation of relevant social conditions—and that these methods are both morally justified and sufficient for good social policy. We present and defend our own preferred model for dealing with dangerous criminals, an incapacitation account built on the right to self-protection analogous to the justification for quarantine (see Pereboom 2001, 2013, 2014a; Caruso 2016a), and we respond to recent objections to it by Michael Corrado and John Lemos.

A unique anthology featuring contributions to the dispute over free will from Aristotle to the twenty-first century, Derk Pereboom's volume presents the most thoughtful positions taken in this crucial debate and discusses their consequences for free will's traditional corollary, moral responsibility. The Second Edition retains the organizational structure that made its predecessor the leading anthology of its kind, while adding major new selections by such philosophers as Spinoza, Reid, John Martin Fischer, Robert Kane, Galen Strawson, and Timothy O'Connor. (...) _Hackett Readings in Philosophy_ is a versatile series of compact anthologies, each devoted to a topic of traditional interest. Selections include classical, modern, and contemporary writings chosen for their elegance of exposition and success at stimulating thought and discussion. (shrink)

According to the Principle of Alternative Possibilities, an agent is morally responsible for an action of hers only if she could have done otherwise. The notion of a robust alternative plays a prominent role in recent attacks on PAP based on so-called Frankfurt cases. In this paper I defend the truth of PAP for blameworthy actions against Frankfurt cases recently proposed by Derk Pereboom and David Widerker. My defence rests on some intuitively plausible principles that yield a new (...) understanding of the concept of a robust alternative. I will leave aside whether PAP also holds for praiseworthy actions -/- Según el Principio de Posibilidades Alternativas, un agente es moralmente responsable de una acción sólo si hubiera podido actuar de otro modo. La noción de alternativa robusta desempeña un papel prominente en ataques recientes al PPA basados en los llamados casos Frankfurt. En este artículo defiendo el PPA para la culpabilidad moral frente a casos Frankfurt propuestos recientemente por Derk Pereboom y David Widerker. Mi defensa descansa en algunos principios intuitivamente plausibles que dan lugar a una comprensión nueva del concepto de alternativa robusta. No trataré la cuestión de la verdad del PPA para acciones moralmente laudables. (shrink)

Nomy Arpaly rejects the model of rationality used by most ethicists and action theorists. Both observation and psychology indicate that people act rationally without deliberation, and act irrationally with deliberation. By questioning the notion that our own minds are comprehensible to us--and therefore questioning much of the current work of action theorists and ethicists--Arpaly attempts to develop a more realistic conception of moral agency.

In _Living Without Free Will_, I develop and argue for a view according to which our being morally responsible would be ruled out if determinism were true, and also if indeterminism were true and the causes of our actions were exclusively events.¹ Absent agent causation, indeterministic causal histories are as threatening to moral responsibility as deterministic histories are, and a generalization argument from manipulation cases shows that deterministic histories indeed undermine moral responsibility. Agent causation has not been ruled out as (...) a coherent possibility, but it is not credible given our best physical theories. Hence we must take seriously the prospect that we are not free in the sense required for moral responsibility. I call the resulting view _hard incompatibilism_. Furthermore, contrary to widespread belief, a conception of life without free will would not at all be devastating to morality or to our sense of meaning in life, and in certain respects it may even be beneficial.

Much of the recent philosophical discussion about free will has been focused on whether compatibilists can adequately defend how a determined agent could exercise the type of free will that would enable the agent to be morally responsible in what has been called the basic desert sense :5–24, 1994; Fischer in Four views on free will, Wiley, Hoboken, 2007; Vargas in Four views on free will, Wiley, Hoboken, 2007; Vargas in Philos Stud, 144:45–62, 2009). While we agree with (...) Derk Pereboom and others that the compatibilist’s burden should be properly understood as providing a compelling account of how a determined agent could be morally responsible in the basic desert sense, the exact nature of this burden has been rendered somewhat unclear by the fact that there has been no definitive account given as to what the basic desert sense of moral responsibility amounts to. In Sect. 1 we set out to clarify the compatibilist’s burden by presenting our account of basic desert moral responsibility—which we call retributivist desert moral responsibility for purposes of clarity—and explain why it is of central philosophical and practical importance to the free will debate. In Sect. 2 we employ a thought experiment to illustrate the kind of difficulty that compatibilists of any stripe are likely to encounter in attempting to explain how determined agents can exercise the kind of free will needed for retributivist desert moral responsibility.

During the 'sixties and 'seventies, Hilary Putnam, Jerry Fodor, and Richard Boyd, among others, developed a type of materialism that eschews reductionist claims.¹ In this view, explana- tions, natural kinds, and properties in psychology do not reduce to counterparts in more basic sciences, such as neurophysiology or physics. Nevertheless, all token psychological entities-- states, processes, and faculties--are wholly constituted of physical entities, ultimately out of entities over which microphysics quantifies. This view quickly became the standard position in philosophy of mind, (...) and reductionism fell out of favor. Recently, however, reductionism has been experiencing a rebirth, and many have suggested that the non-reductive approach was accepted too quickly and too uncritically. In this paper, we attempt to provide a more thorough account of the anti-reductionist position, and, in the process, to defend it against its recent critics. (shrink)

Transcendental freedom consists in the power of agents to produce actions without being causally determined by antecedent conditions, nor by their natures, in exercising this power. Kant contends that we cannot establish whether we are actually or even possibly free in this sense. He claims only that our conception of being transcendentally free involves no inconsistency, but that as a result the belief that we have this freedom meets a pertinent standard of minimal credibility. For the rest, its justification depends (...) on practical reasons. I argue that this belief satisfies an appropriately revised standard of minimal credibility, but that the practical reasons Kant adduces for it are subject to serious challenge. (shrink)

I have presented a Frankfurt-style argument (Pereboom 2000, 2001, 2003) against the requirement of robust alternative possibilities for moral responsibility that features an example, Tax Evasion , in which an agent is intuitively morally responsible for a decision, has no robust alternative possibilities, and is clearly not causally determined to make the decision. Here I revise the criterion for robustness in response to suggestions by Dana Nelkin, Jonathan Vance, and Kevin Timpe, and I respond to objections to the argument (...) by Carlos Moya and David Widerker, in the process of which I refine the Tax Evasion example. (shrink)

The claim that moral responsibility for an action requires that the agent could have done otherwise is surely attractive. Moreover, it seems reasonable to contend that a requirement of this sort is not merely a necessary condition of little consequence, but that it plays a decisive role in explaining an agent's moral responsibility for an action. For if an agent is to be blameworthy for an action, it seems crucial that she could have done something to avoid this blameworthiness. If (...) she is to be praiseworthy for an action, it seems important that at least she could have done something less admirable. Libertarians, in particular, have often grounded their incompatibilism precisely in such intuitions. By contrast, I shall argue that the availability of alternative possibilities is in a significant sense irrelevant to explaining an agent's moral responsibility for an action. At the same time I do not want to disavow incompatibilism, but rather to defend a version in which the pivotal explanatory role is assigned to features of the causal history of the action, and not to the availability of alternative possibilities.
