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.

If we have libertarian free will, then it is plausible to believe that the occurrences of certain physical events have irreducible and ineliminable mental explanations. According to a strong version of naturalism, everything in the physical world is in principle explicable in nonmental terms. Therefore, the truth of naturalism implies that libertarian choices cannot explain the occurrences of any physical events. In this paper, I example a methodological argument for the truth of naturalism and conclude that (...) the argument fails. I then consider additional concerns raised against the reality of libertarian freedom. First, I examine the claim that if a physical event E is not causally determined to occur by another physical event, then there is no way to account for the difference between E’s occurring randomly and E’s being causally determined to occur by a mental event. Second, I consider the assertion that the affirmation of libertarianism is a mind-of-the-gaps version of the God-of-the-gaps objection to a divine explanation of a physical event. Third, I take up the question of whether the inability of libertarians to pinpoint precisely where the initial physical effects of libertarian choices occur is a good reason for rejecting libertarianism. Fourth, I examine the claim that belief in the existence of the soul or immaterial mind is the result of an explanatory hypothesis to account for how libertarian free choices can causally produce physical effects. Fifth, I look at the traditional objection to substance dualism from the impossibility of causal interaction between a soul and its body. (shrink)

This book is a collection of new essays on the libertarian position on free will and related issues that focuses specifically on the views of philosopher Robert Kane. Written by a distinguished group of philosophers, the essays range from various areas of philosophy including metaphysics, ethics, and philosophy of mind.

While other philosophers have pointed out that Libet's experiment is compatible with compatibilist free will and also with weak libertarian free will, this article argues that it is even compatible with strong libertarian free will (SLF), \ie a person's ability to initiate causal processes. Contrary to what Libet suggested, the actions in the experiment were motivated by urges. It is in accordance with SLF that the urges had preceding unconcious causes. Furthermore, Libet's (...) observation that vetoing is possible confirmes SLF. (shrink)

A Pragmatic Approach to Libertarian Free Will argues that the kind of free will required for moral responsibility and just desert is libertarian free will. It is a source of great controversy whether such a libertarian view is coherent and whether we should believe that we have such free will. This book explains and defends Robert Kane¿s conception of libertarian free will while departing from it in (...) certain key respects. It is argued that a suitably modified Kanean model of free will can be shown to be conceptually coherent. In addition, it is argued that while we lack sufficient epistemic grounds supporting belief in the existence of libertarian free will, we may still be justified in believing in it for moral reasons. As such, the book engages critically with the works of a growing number of philosophers who argue that we should jettison belief in the existence of desert-grounding free will and the practices of praise and blame and reward and punishment which it supports.

Libertarians make indeterminism a requirement of free will. But many argue that indeterminism is destructive of free will because it reduces an agent’s control. This paper argues that such concerns are misguided. Indeterminism, at least as it is located by plausible Libertarian views, poses no threat to an agent’s control, nor does it pose any other kind of threat.

Libertarian free will is, roughly, the view that the same agential states can cause different possible actions. Nonreductive physicalism is, roughly, the view that mental states cause actions to occur, while these actions also have sufficient physical causes. Though libertarian free will and nonreductive physicalism have overlapping subject matter, and while libertarian free will is currently trending at the same time as nonreductive physicalism is a dominant metaphysical posture, there are few (...) sustained expositions of a nonreductive physicalist model of libertarian free will – indeed some tell against such an admixture. This paper concocts such a blend by articulating and defending, with some caveats, a nonreductive physicalist model of libertarian free will. (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.

An agent who is the victim of covert and nonconstraining control is unaware of being controlled and controllers get their way by manipulating the victims so that they willingly do what the controllers desire. Our primary objective is to argue that if cases of CNC manipulation undermine compatibilist accounts of the sort of control required for moral responsibility, they also undermine various agent‐causal and non‐agent‐causal libertarian accounts as well.

The first purpose of this article is to present a new theory of libertarian free will—the boundary theory of libertarian free will—which provides a new framework by means of employing boundaries as a “conceptual scheme” for understanding libertarian free will. This theory consists of two parts. One part suggests that the agent’s will should be viewed as the intermediate boundary between an agent’s reasons and his alternative choices. The second part (...) is a model where the agent’s will is a faculty that solely operates by permitting or resisting reasons (that are potential causes) to become actual causes for the agent’s choices. The second purpose of the paper is to argue that the boundary theory of libertarian free will has several advantages, the most important of which are: (a) it defeats the charge that libertarian free will is a mystery; (b) it defeats the standard objections against the compatibility of libertarian free will and indeterminism (that is, the luck argument, the roll-back argument, the difference argument, the assimilation argument, etc.); and (c) it is simultaneously an argument for indeterminism as such (that is, that determinism is false).

People have disagreed on the significance of Libet-style experiments for discussions about free will. In what specifically concerns free will in a libertarian sense, some argue that Libet-style experiments pose a threat to its existence by providing support to the claim that decisions are determined by unconscious brain events. Others disagree by claiming that determinism, in a sense that conflicts with libertarian free will, cannot be established by sciences other than fundamental physics. (...) This paper rejects both positions. First, it is argued that neuroscience and psychology could in principle provide support for milder deterministic claims that would also conflict with libertarian free will. Second, it is argued that Libet-style experiments—due to some of their peculiar features, ones that need not be shared by neuroscience as a whole—currently do not support such less demanding deterministic claims. The general result is that neuroscience and psychology could in principle... (shrink)

In a recent paper in this journal, “How should libertarians conceive of the location and role of indeterminism?” Christopher Evan Franklin critically examines my libertarian view of free will and attempts to improve upon it. He says that while Kane's influential [view] offers many important advances in the development of a defensible libertarian theory of free will and moral responsibility … [he made] “two crucial mistakes in formulating libertarianism” – one about the location of (...) indeterminism, the other about its role – “both of which have helped fan the flame of the luck argument”. In this paper, I respond to Franklin's criticisms, arguing that, so far from making it significantly more difficult to answer objections about luck and control, as he claims, giving indeterminism the location and role I do makes it possible to answer such objections and many other related objections to libertarian free will. A central theme of this paper will emerge in my responses: In order to make sense of freedom of will... (shrink)

This comprehensive study offers a balanced assessment of libertarian accounts of free will. Bringing to bear recent work on action, causation, and causal explanation, Clarke defends a type of event-causal view from popular objections concerning rationality and diminished control. He subtly explores the extent to which event-causal accounts can secure the things for the sake of which we value free will, judging their success here to be limited. Clarke then sets out a highly original agent-causal (...) account, one that integrates agent causation and nondeterministic event causation. He defends this view from a number of objections but argues that we should find the substance causation required by any agent-causal account to be impossible. Clarke concludes that if a broad thesis of incompatibilism is correct--one on which both free will and moral responsibility are incompatible with determinism--then no libertarian account is entirely adequate.

Walter applies the methodology of neurophilosophy to one of philosophy's centralchallenges, the notion of free will. Neurophilosophical conclusions are based on, and consistentwith, scientific knowledge about the brain and its functioning.

This article articulates and defends an indeterministic weightings model of libertarian free will. It begins by defining the conception of free will at issue and then goes on to present versions of the luck objection which is often made against theories of LFW. It is argued that the sort of indeterministic weightings model of LFW which has been defended in the recent literature by Storrs McCall and E.J. Lowe and John Lemos has the resources to (...) answer such luck objections while possessing virtues which some other libertarian views lack. According to the indeterministic weightings model of LFW, in making undetermined free-willed choices between two courses of action, A or B, the reasons for choosing each option don’t come with pre-established evaluative weights. During the process of deliberation, the agent assigns weight in an undetermined way to the reasons for each option and this typically leads to the choice of the option that has been assigned a greater value. In the paper, it is not only argued that this theory can resolve worries about luck but also that the view has virtues which certain other libertarian views lack, as such the view is contrasted with the modest libertarian models of LFW from Daniel Dennett and Alfred Mele as well as Robert Kane’s view.

As pop naturalists tell it, free will is incompatible with naturalism. And apparently many scientists agree. Philosopher Daniel Dennett reports, for example, that he has “learned from discussions with a variety of scientists…[that] free will, in their view, is obviously incompatible with naturalism, with determinism, and very likely incoherent against any background, so they cheerfully insist that of course they don’t have free will” (2013, 47). Many philosophers, however, disagree (e.g., Mele 2014; Nahmias 2014; (...) Vargas 2014), since compatibilist forms of free will seem amendable to purely naturalist underwriting. There is nevertheless, among philosophers, a near consensus on this: naturalism is certainly incompatible with libertarian free will. We aim to show in this paper that free will is not incompatible with naturalism. Even the purportedly “spooky” – or “colossally whackadoodle”2 – libertarian form of free will known as agent causation can be situated within a naturalistic metaphysical framework. Neither of us, though, is a naturalist,3 and you know what they say about enemies bearing gifts. Still, our goal in this chapter is to offer a framework for an agent‐causal account of free will that naturalists should be able to accept. (shrink)

Let libertarianism be the view that humans are capable of making decisions that are simultaneously undetermined and appropriately non-random. It’s often argued that this view is incoherent because indeterminacy entails randomness (of some appropriate kind). I argue here that the truth is just the opposite: the right kind of indeterminacy in our decisions actually entails appropriate non-randomness, so that libertarianism is coherent, and the question of whether it’s true reduces to the wide-open empirical question of whether certain of our decisions (...) (which I characterize here) are undetermined at the moment of choice. Moreover, the version of libertarianism developed here is entirely naturalistic and event-causal. (shrink)

In recent work, I defend an indeterministic weightings model of libertarian free will. (Lemos, 2018, Ch. 5; 2021; 2023, Ch. 6). On this view, basic free-willed actions are understood as the result of causally indeterminate deliberative processes in which the agent assigns evaluative weight to the reasons for the different choice options under consideration. In basic free-willed actions, the assignment of weights is causally undetermined, and the choices are typically the causal consequence of these assignments (...) of weights in which the choice option that is more highly valued is the choice option selected. In a recent article, Ishtiyaque Haji (2022) criticizes my view, arguing that it: (a) does not resolve worries about luck and (b) does not make coherent sense of the freedom of the weightings involved in free choices. I argue that his criticisms are based on misunderstandings of my position. (shrink)

This essay has two primary theses: (1) we ought to desire libertarian free will if we want to be as good as we can possibly be, and (2) we can be as good as we can possibly be only if we possess libertarian free will. A libertarian free being, in virtue of being able to refrain from evil under certain epistemic conditions, has access to an order of goodness higher than his determined (...) counterpart could possibly have. Libertarian freedom, therefore, is preferable to compatibilist free will mainly in virtue of its role in the making of optimally good people. (shrink)

Free Will is constituted by a desire to act that is based on practical reasons. Being guided by reasons constitutes human agency. The reasons account, which I will develop in this paper, is libertarian, as it implies that human agency is naturalistically underdetermined. Naturalistic descriptions, referring exclusively to natural causes, are not able to fully describe and explain human agency. On the other hand, there are no scientific arguments for the assumption that the causal impact of (...) reasons interferes with the laws of physics. The physical world can - in principle - be described and explained within the conceptual frame of the natural sciences. The causal impact of reasons does not interfere with the laws of physics. Therefore, my reasons account of Free Will is also compatibilist. (shrink)

In this largely antimetaphysical treatment of free will and determinism, Mark Balaguer argues that the philosophical problem of free will boils down to an open scientific question about the causal histories of certain kinds of neural events. In the course of his argument, Balaguer provides a naturalistic defense of the libertarian view of free will. The metaphysical component of the problem of free will, Balaguer argues, essentially boils down to the question (...) of whether humans possess libertarian free will. Furthermore, he argues that, contrary to the traditional wisdom, the libertarian question reduces to a question about indeterminacy--in particular, to a straightforward empirical question about whether certain neural events in our heads are causally undetermined in a certain specific way; in other words, Balaguer argues that the right kind of indeterminacy would bring with it all of the other requirements for libertarian free will. Finally, he argues that because there is no good evidence as to whether or not the relevant neural events are undetermined in the way that's required, the question of whether human beings possess libertarian free will is a wide-open empirical question.

Restorative Free Will examines free will as an adaptive capacity that evolved in humans and many other species, and restores free will to species excluded by claims of human uniqueness. Restorative Free Will recognizes the basic biological value of both libertarian and compatibilist elements of free will, and explains how these traditionally opposed accounts of free will capture an essential element of foraging animals' free will.

In this comprehensive new study of human free agency, Laura Waddell Ekstrom critically surveys contemporary philosophical literature and provides a novel account of the conditions for free action. Ekstrom argues that incompatibilism concerning free will and causal determinism is true and thus the right account of the nature of free action must be indeterminist in nature. She examines a variety of libertarian approaches, ultimately defending an account relying on indeterministic causation among events and appealing (...) to agent causation only in a reducible sense. Written in an engaging style and incorporating recent scholarship, this study is critical reading for scholars and students interested in the topics of motivation, causation, responsibility, and freedom. In broadly covering the important positions of others along with its exposition of the author’s own view, Free Will provides both a significant scholarly contribution and a valuable text for courses in metaphysics and action theory.

The aim of this paper is to challenge libertarian accounts of free will. It is argued that there is an irreconcilable tension between the way in which philosophers motivate the incompatibilist ability to do otherwise and the way in which they formally express it. Potential incompatibilist responses in the face of this tension are canvassed, and it is argued that each response is problematic. It is not claimed that incompatibilist accounts in general are incoherent, but rather that (...) any incompatibilist account that requires that an agent have alternative possibilities at the point of a free action fails.

If my ability to react freely is constrained by forces beyond my control, am I still morally responsible for the things I do? The question of whether, how and to what extent we are responsible for our own actions has always been central to debates in philosophy and theology, and has been the subject of much recent research in cognitive science. And for good reason- the views we take on free will affect the choices we make as individuals, (...) the moral judgments we make of others, and they will inform public policy. Michael McKenna's text introduces this important subject with remarkable clarity, offering the first comprehensive overview of both incompatibilist and compatibilist stances. He begins by motivating both viewpoints, then provides classical accounts of each before giving students an in-depth examination of current scholarship in the free will debate. Topics covered include: the nature of free will the nature of determinism the nature of moral responsibility arguments for the incompatibility of free will and determinism arguments of the compatibility of free will and determinism libertarian theories of free will and moral responsibility compatibilist theories of free will and moral responsibility hard determinist and hard incompatibilist theories.

This is a work concerned with justification and freedom and the relationship between these. Its summational aim is to defend a transcendental argument for free will – that we could not be epistemically justified in undermining a strong notion of free will, as a strong notion of free will would be required for any such process of undermining to be itself epistemically justified. The book advances two transcendental arguments – for a deontically internalist conception (...) of epistemic justification and the aforementioned argument for a libertarian conception of free will. In defending each of these arguments, the book both defends and relies upon the principle that ‘ought’ implies ‘can’. In articulating the latter transcendental argument – for freedom – heavy reliance is made on the earlier, epistemic, work: especially on the deontological conception of rational justification (on epistemic internalism).

Philosophers often consider problems of free will and moral luck in isolation from one another, but both are about control and moral responsibility. One problem of free will concerns the difficult task of specifying the kind of control over our actions that is necessary and sufficient to act freely. One problem of moral luck refers to the puzzling task of explaining whether and how people can be morally responsible for actions permeated by factors beyond their control. (...) This chapter explicates and assesses skeptical, compatibilist, and libertarian approaches to moral luck. First, I argue that what makes the above problems of free will and moral luck distinct is largely their emphasis on different kinds of luck. Second, I describe and evaluate skeptical arguments from constitutive and circumstantial luck that it is impossible to act freely. Third, I explicate and assess various support and implication relationships between various kinds of compatibilism and libertarianism, on the one hand, and causal, constitutive, circumstantial, and resultant moral luck, on the other.

Denialism concerning free will and moral responsibility combines, in its minimal form, the rejection of libertarian free will and the rejection of compatibilism. I will address the more ambitiously “happy” or “optimistic” version of denialism, which also claims that we are better off without belief in free will and moral responsibility, and ought to try to radically reform our moral, social and personal lives without such beliefs. I argue that such denialism involves, (...) for various reasons, a dangerous gamble, which it would be morally irresponsible to follow. I conclude by reflecting upon the implications. (shrink)

Libertarians such as J.R. Lucas have abandoned traditional Christian doctrines because they cannot reconcile them with the freedom of the will. Traditional Christian thinkers such as Augustine have repudiated libertarianism because they cannot reconcile it with the dogmas of the Faith. In Free Will and the Christian Faith, W.S. Anglin demonstrates that free will and traditional Christianity are ineed compatible. He examines, and solves, puzzles about the relationships between free will and omnipotence, omniscience, (...) and God's goodness, using the idea of free will to answer the question of why God allows evil, and presenting arguments that link free will to eternal life and to the nature of revelation. Topics covered include the meaning of life, the soul and Lesbegue measure, and strategies for discerning the voice of God. (shrink)

The thesis of this article is that there has never been any ground for the controversy between the doctrine of free will and determinism, that it is based upon a misapprehension, that the two assertions are entirely consistent, that one of them strictly implies the other, that they have been opposed only because of our natural want of the analytical imagination. In so saying I do not tamper with the meaning of either phrase. That would be unpardonable. I (...) mean free will in the natural and usual sense, in the fullest, the most absolute sense in which for the purposes of the personal and moral life the term is ever employed. I mean it as implying responsibility, merit and demerit, guilt and desert. I mean it as implying, after an act has been performed, that one " could have done otherwise " than one did. I mean it as conveying these things also, not in any subtly modified sense but in exactly the sense in which we conceive them in life and in law and in ethics. These two doctrines have been opposed because we have not realised that free will can be analysed without being destroyed, and that determinism is merely a feature of the analysis of it. And if we are tempted to take refuge in the thought of an "ultimate ", an "innermost" liberty that eludes the analysis, then we have implied a deterministic basis and constitution for this liberty as well. For such a basis and constitution lie in the idea of liberty. -/- The thesis is not, like that of Green or Bradley, that the contending opinions are reconciled if we adopt a certain metaphysic of the ego, as that it is timeless, and identifies itself with a desire by a " timeless act". This is to say that the two are irreconcilable, as they are popularly supposed to be, except by a theory that delivers us from the conflict by taking us out of time. Our view on the contrary is that from the natural and temporal point of view itself there never was any need of a reconciliation but only of a comprehension of the meaning of terms. (The metaphysical nature of the self and its identity through time is a problem for all who confront memory, anticipation, etc.; it has no peculiar difficulties arising from the present problem.) -/- I am not maintaining that determinism is true; only that it is true insofar as we have free will. That we are free in willing is, broadly speaking, a fact of experience. That broad fact is more assured than any philosophical analysis. It is therefore surer than the deterministic analysis of it, entirely adequate as that in the end appears to be. But it is not here affirmed that there are no small exceptions, no slight undetermined swervings, no ingredient of absolute chance. All that is here said is that such absence of determination, if and so far as it exists, is no gain to freedom, but sheer loss of it; no advantage to the moral life, but blank subtraction from it. -- When I speak below of "the indeterminist" I mean the libertarian indeterminist, that is, him who believes in free will and holds that it involves indetermination.

According to the libertarian view of free will, people sometimes act freely, but this freedom is incompatible with causal determinism. Goetz has developed an important and unusual libertarian view of free will. Rather than simply arguing that a person's free actions cannot be causally determined, Goetz argues that they cannot be caused at all. According to Goetz, in order for a person to act freely, her actions must be uncaused.1 My aim in this (...) essay is to evaluate Goetz's “noncausal” libertarian view of free will. In section 1, I outline Goetz's view. In section 2, I develop two criticisms of his view. In section 3, I develop an improved “positive” account of the noncausal view, which takes Goetz's metaphysical framework as its point of departure but is not subject to the criticisms that plague his development of this framework. Finally, in section 4, I respond to some objections to my proposed noncausal view. (shrink)

In response to the increasingly popular manipulation argument against compatibilism, some have argued that libertarian accounts of free will are vulnerable to parallel manipulation arguments, and thus manipulation is not uniquely problematic for compatibilists. The main aim of this article is to give this point a more detailed development than it has previously received. Prior attempts to make this point have targeted particular libertarian accounts but cannot be generalized. By contrast, I provide an appropriately modified manipulation (...) that targets all libertarian accounts of freedom and responsibility—an especially tricky task given that libertarian accounts are a motley set. I conclude that if manipulation arguments reveal any theoretical cost then it is one borne by all accounts according to which we are free and responsible, not by compatibilism in particular.

The question of whether humans have free will, like the question of the meaning of life, is one whose answer depends on how the question itself is interpreted. In his recent book Neurophilosophy of Free Will: From Libertarian Illusions to a Concept of Natural Autonomy, Henrik Walter examines whether free will is possible in a deterministic natural world, and he concludes that the answer is "It depends" (xi). He rejects a libertarian account (...) of free will as internally inconsistent, but argues for a version of compatibilism that he calls "natural autonomy." Natural autonomy, or "giving oneself laws" (8), is a successor concept to libertarian free will, and it provides for a self-determination that is consistent with a deterministic and fully physical world. Walter covers a lot of ground in this book. He debunks dualism, examines classical and modern physics, critiques radical constructivism, and utilizes chaos theory, and he refers to figures from St. Augustine to Humberto Maturana, Dennett, Einstein, Hegel and Nozick. This book could be seen as encompassing two distinct projects. The first project is a defense of what Walter calls "neurophilosophy" as a methodology for answering traditional philosophical questions. This methodology is more commonly known as "cognitive science," and Walter accepts the naturalistic premises that underlie most of the work being done by cognitive scientists today. The second project is an application of the neurophilosophical methodology to the traditional question of whether free will is compatible with determinism. The defense of a neurophilosophical methodology is concentrated in the second section of the book, whereas the first and third sections focus on the issue of free will. In the first section Walter presents a thorough overview of the free will debate. It is the final third of the book that warrants the most attention, for this is where the original work is concentrated. Before we examine Walter's contribution to the free will debate, let us briefly look at his historical analysis and the neurophilosophical method that he advocates.. (shrink)
