Free Will Skepticism

Can we be held morally responsible for our actions? Yes, says Daniel Dennett. No, says Gregg Caruso. Reader, you decide.

The discussion in this paper begins with some observations regarding a number of structural similarities between art and morality as it involves human agency. On the basis of these observations we may ask whether or not incompatibilist worries about free will are relevant to both art and morality. One approach is to claim that libertarian free will is essential to our evaluations of merit and desert in both spheres. An alternative approach, is to claim that free will is required only (...) in the sphere of morality—and that to this extent the art/morality analogy breaks down. I argue that both these incompatibilist approaches encounter significant problems and difficulties—and that incompatibilist have paid insufficient attention to these issues. However, although the analogy between art and morality may be welcomed by compatibilists, it does not pave the way for an easy or facile optimism on this subject. On the contrary, while the art/morality analogy may lend support to compatibilism it also serves to show that some worries of incompatibilism relating to the role of luck in human life cannot be easily set aside, which denies compatibilism any basis for complacent optimism on this subject.

This collection provides a selection of the most essential contributions to the contemporary free will debate. Among the issues discussed and debated are skepticism and naturalism, alternate possibilities, the consequence argument, libertarian metaphysics, illusionism and revisionism, optimism and pessimism, neuroscience and free will, and experimental philosophy.

Throughout much of the first half of the twentieth century, the free-will debate was largely concerned with the question of what kind of freedom was required for moral responsibility and whether the kind of freedom required was compatible with the thesis of determinism. This issue was itself addressed primarily with reference to the question of how freedom is related to alternative possibilities and what the relevant analysis of “could have done otherwise” comes to. The discussion of these topics made little (...) advance on the basic strategies and positions already developed and defended on either side of the compatibilist/incompatibilist divide in the preceding two centuries. When P. F. Strawson’s published his seminal article “Freedom and Resentment” in 1962 the dynamics of this debate were fundamentally altered. This is true both in respect of Strawson’s general methodology, which demands a more empirically informed approach, and in terms of his core conceptual framework, which identifies a different set of considerations and issues at the heart of this debate. In particular, whereas the traditional or classical debate focused on the problem of (moral) freedom, Strawson directed his attention to the role of moral sentiments or “reactive attitudes” as the key to understanding and resolving the core problems lying at the heart of this debate. This essay is devoted to a critical assessment of Strawson’s project and an analysis of the current debate concerning its prospects. (shrink)

.... The strategy I have defended involves drawing a distinction between those who can and cannot legitimately hold an agent responsible in circumstances when the agent is being covertly controlled (e.g. through implantation processes). What is intuitively unacceptable, I maintain, is that an agent should be held responsible or subject to reactive attitudes that come from another agent who is covertly controlling or manipulating him. This places some limits on who is entitled to take up the participant stance in relation (...) to agents who are rational self-controllers but nevertheless subject to covert control.26 In this way, what is compromised by conditions of covert control is not the responsibility of the agent as such. It is, rather, the participant stance of those other agents who covertly control him. Clearly it is possible to establish these specific limits on who can hold these agents responsible without denying that the agents themselves remain free and responsible. When we take this approach we will find that we are no longer faced with an unattractive choice between simply “biting the bullet” or having to “spit it out”. All we need to do is chew carefully, until there is nothing left that we find too hard to swallow. (shrink)

In the third and final part of his A Theory of Determinism (TD) Ted Honderich addresses the fundamental question concerning “the consequences of determinism.” The critical question he aims to answer is what follows if determinism is true? This question is, of course, intimately bound up with the problem of free will and, in particular, with the question of whether or not the truth of determinism is compatible or incompatible with the sort of freedom required for moral responsibility. It is (...) Honderich’s aim to provide a solution to “the problem of the consequences of determinism” and a key element of this is his articulation and defence of an alternative response to the implications of determinism that collapses the familiar Compatibilist/Incompatibilist dichotomy. Honderich offers us a third way – the response of “Affirmation” (HFY 125-6). Although his account of Affirmation has application and relevance to issues and features beyond freedom and responsibility, my primary concern in this essay will be to examine Honderich’s theory of “Affirmation” as it concerns the free will problem.

One of the most intriguing problems of philosophy and of mankind is the question whether humans have a free will. This question is heavily disputed between natural scientists and especially neuroscientists, who deny free will, and philosophers and other groups, who insist on free will. It is perplexing that both sides base their premise on the same precondition, namely naturalism. We will prove that naturalism automatically leads to physicalism, to materialism, and to reductionism. We will also prove here that it (...) is logically not possible to have a free will if naturalism is true. Free will definitely requires an additional substance, a non-material soul, which cannot be part of our universe. This must not be in contradiction to our current knowledge of natural sciences.

Resumen: El presente escrito tiene por objetivo discutir los alcances de la postura denominada escepticismo sobre el libre albedrío y evaluar si el debate compatibilismo - incompatibilismo supone una postura racionalista y/o necesitarista respecto a si un sujeto S actúa libremente. La discusión de los últimos diez años sobre este tópico permite establecer una distinción relevante entre que una acción sea libre, sin que ello descarte antecedentes causales de esa acción. En particular, sin que ello conduzca a un compromiso con (...) el denominado principio de posibilidades alternativas ni con el denominado argumento consecuencial. Se discutirá cómo el experimento desarrollado por Libet comprende el si una acción libre es equivalente a una acción consciente, considerando la relevancia de la libertad de veto y el rol del criterio de control de una acción. Una arista relevante en este análisis será la postura epifenomenalista. Finalmente, se evaluará la alternativa modal denominada imposibilismo y su rol en una postura escéptica respecto al libre albedrío.: This paper discusses the free will scepticism claim and discerns whether the compatibilism - incompatibilism debate presupposes a rationalistic/necessitarism stance about if a subject S acts freely. The last ten years makes it possible to establish a relevant distinction between an action being free, without discarding causal antecedents of that action. Specifically, this does not lead to a compromise with the so-called Principle of Alternative Possibilities or with the Consequence Argument. It will be discussed how the experiment developed by Libet comprises whether a free action is equivalent to a conscious action, considering the relevance of freedom of veto and the role of the control criterion of an action. A relevant edge in this analysis will be the epiphenomenalist stance. Finally, it will be evaluated the impossibilist modal alternative and its role in a sceptical position regarding free will.

The immediate aim of this paper is to articulate the essential features of an alternative compatibilist position, one that is responsive to sources of resistance to the compatibilist program based on considerations of fate and luck. The approach taken relies on distinguishing carefully between issues of skepticism and pessimism as they arise in this context. A compatibilism that is properly responsive to concerns about fate and luck is committed to what I describe as free will pessimism, which is to be (...) distinguished from free will skepticism. Free will skepticism is the view that our vulnerability to conditions of fate and luck serve to discredit our view of ourselves as free and responsible agents. Free will pessimism rejects free will scepticism, since the basis of its pessimism rests with the assumption that we are free and responsible agents who are, nevertheless, subject to fate and luck in this aspect of our lives. According to free will pessimism, all the major parties and positions in the free will debate, including that of skepticism, are modes of evasion and distortion regarding our human predicament in respect of agency and moral life.

: What is at stake in the debate between those, such as Sam Harris and me, who contend that we would lack free will on the supposition that we are causally determined agents, and those that defend the claim that we might then retain free will, such as Daniel Dennett? I agree with Dennett that on the supposition of causal determination there would be robust ways in which we could shape, control, and cause our actions. But I deny that on (...) this supposition we would have the control in action required for us to basically deserve to be blamed, praised, punished or rewarded. In this response, I argue that this is the core issue that divides compatibilists and incompatiblists about free will and causal determination, and that the incompatibilist position is the right one to accept. Keywords: Sam Harris; Daniel Dennett; Free Will Skepticism; Compatibilism; Incompatibilism Risposta a Daniel Dennet sullo scetticismo circa il libero arbitrio Riassunto: Qual è la posta in gioco nel dibattito che vede contrapporsi chi – come Sam Harris e me – sostiene che non avremmo libertà di volere sulla scorta dell’ipotesi per cui siamo agenti causalmente determinati e chi, al contrario – come Daniel Dennett – difende l’idea che possa darsi un libero volere? Concordo con Dennett circa il fatto che, anche nell’ipotesi della determinazione causale, resterebbe lo spazio per sostenere che per vari e importanti aspetti saremmo comunque noi a modellare, controllare e causare le nostre azioni. E tuttavia rifiuto che su questa base avremmo il controllo in azioni richieste per meritare di essere biasimati, lodati, puniti o premiati. A mio avviso questo è l’elemento cardine che divide i compatibilisti dagli incompatibilisti all’interno del dibattito sul libero arbitro e sulla determinazione causale e ritengo che la posizione corretta sia quella incompatibista. Parole chiave: Sam Harris; Daniel Dennett; Scetticismo verso il libero arbitrio; Compatibilismo; Incompatibilismo. (shrink)

In contemporary free will theory, a significant number of philosophers are once again taking seriously the possibility that human beings do not have free will, and are therefore not morally responsible for their actions. (Free will is understood here as whatever satisfies the control condition of moral responsibility.) Free will theorists commonly assume that giving up the belief that human beings are morally responsible implies giving up all our beliefs about desert. But the consequences of giving up the belief that (...) we are morally responsible are not quite this dramatic. Giving up the belief that we are morally responsible undermines many, and perhaps most, of the desert claims we are pretheoretically inclined to accept. But it does not undermine desert claims based on the sheer fact of personhood. Even in the absence of belief in moral responsibility, personhood-based desert claims require us to respect persons and their rights. So personhood-based desert claims can provide a substantial role for desert in free will skeptics' ethical theories. (shrink)

Over the last three decades there has been a tremendous amount of philosophical work in the Anglo-American tradition on the cluster of topics pertaining to Free Will. Contemporary work has in some instances been in the form of lively debates between proponents of different viewpoints, and literature surrounding the area is therefore characterized by a genuine vitality. This collection selects the very best of this material and presents it in a single, accessible set of volumes.

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.

While skeptical arguments concerning free will have been a common element of philosophical discourse for thousands of years, one could make the case that such arguments have never been more numerous or forceful than at present. In response to these skeptical attacks, some philosophers and psychologists have expressed concern that the widespread acceptance of such skeptical attitudes could have devastating social consequences. In this paper, I set out to address whether such concerns are well-founded. I argue that there is reason (...) to believe that should skeptical arguments result in the widespread dismissal of human free will, the results of such a dismissal are likely to be more positive than negative.

In Free Will, Agency, and Meaning in Life, Derk Pereboom proposes an optimistic model of life that follows on the rejection of both libertarian and compatibilist beliefs in free will, moral responsibility, and desert. I criticize his views, focusing on punishment. Pereboom responds to my earlier argument that hard determinism must seek to revise the practice of punishment in the direction of funishment, whereby the incarcerated are very generously compensated for the deprivations of incarceration. I claimed that funishment is a (...) practical reductio: of hard determinism. Pereboom replies, but I claim that he misses a key component of my reductio, the idea that moving in the direction of funishment will considerably weaken the deterrence of potential criminals so that hard determinism becomes self-defeating in practice. Beyond the challenge of funishment, I raise various other difficulties with Pereboom’s model, concerning its deeply unintuitive implications, the harm it does to the motivation of potential criminals, its weakness in resisting utilitarian-like dangers, and more. Our conclusions should lead to a re-evaluation of the compatibilist interpretation of moral life, as a richer, more plausible, and safer interpretation than hard determinism. This needs to be combined with a true hard determinist acknowledgment of the deep injustice and tragedy involved in punishment in light of the absence of libertarian free will. Such a complex view will come closer to doing justice to notions of justice, morality, and decency. (shrink)

Moral responsibility skeptics have often focused on problems involving determinism in order to defend their position. I argue that this defense of moral responsibility skepticism is misplaced given that what really matters for moral responsibility is an agent's ability to have morally-relevant control. An account, I call agnostic control, remains viable regardless of the truth of determinism, which means that determinism is the wrong place to look for the denial of moral responsibility. I provide an argument in favour of moral (...) responsibility skepticism, such that differences in ability between agents, which are the result of constitutive luck, are moral responsibility undermining. This is explained by the contrastive fact that agents have differing abilities, which makes praising one agent, and blaming another, inherently unfair. I then defend this skeptical position against three prominent criticisms, that the system of moral responsibility is 'fair enough', that without moral responsibility our participant reactive attitudes would not be justified, and that moral responsibility is required to justify criminal punishment. Contrary to the claim that moral responsibility is 'fair enough' I argue that the system of rewards and punishments, which are justified by moral responsibility, require that moral responsibility have a higher standard of fairness. This is due to the increased significance these rewards and punishments have for the agent. The concern surrounding the reactive attitudes and criminal punishment involves the idea that both are practically necessary for a well-functioning society. The worry is that without moral responsibility the reactive attitudes and criminal punishment would have to be rejected, an outcome which is purportedly undesirable. I address this problem in two ways; either by showing that the purported benefits are not actually beneficial or by showing that the beneficial aspects of each can and should be maintained given moral responsibility skepticism. This means that moral responsibility skepticism remains a viable option. (shrink)

There are generally two controversial issues over Kant's solution to the free will problem. One is over whether he is a compatibilist or an incompatibilist and the other is over whether his solution is a success. In this paper, I will argue, regarding the first controversy, that “compatibilist” and “incompatibilist” are not the right terms to describe Kant for his unique views on freedom and determinism; but that of the two, incompatibilist is the more accurate description. Regarding the second controversy, (...) I will argue that Kant's solution to the free will problem is not a success because his effort in making the effects of freedom part of the field of appearance has made his solution incoherent and ambiguous. Despite this, I argue that Kant's attempt to solve the free will problem is groundbreaking because he at least has separated freedom from the dominance of determinism. (shrink)

Free will skepticism is the view that people never truly deserve to be praised, blamed, or punished for what they do. One challenge free will skeptics face is to explain how criminality could be dealt with given their skepticism. This paper critically examines the prospects of implementing legal changes concerning crime and punishment derived from the free will skeptical views developed by Derk Pereboom and Gregg Caruso. One central aspect of the changes their views require is a concern for reducing (...) the severity of current forms of punishment. The paper considers two strategies for pursuing such a reduction. By taking into account evidence from the psychology of belief in free will and desire to punish, it is argued that a strategy aiming at a reduction of people’s natural desire to punish criminals can be successful if capable of providing alternatives to current forms of punishment satisfying three properties: they must be less harmful than current forms of punishment, more effective in preventing crime, and incompatible with current forms of punishment.

Freedom is an impossibility; the dream of having the ability to choose anything one wants is hampered by reality. However, what aspect of reality ultimately hampers the birth of true freedom? What I propose is that reality itself makes freedom impossible. Furthermore, I also make the logical assumption, from the evidence I have found, that the only entity that can have freedom is a being that is formless, timeless, featureless, and is an infinite environment of nothing. While my studies today (...) haven’t been focused on that topic, it is a noteworthy observation. I also prove Determinism, and show why the definitions of free will given by Libertarians, Compatibilists, and Incompatibilists each, without any argument I could see, fall. I also provide some insight into the reactive basis of human psychology, further proving Determinism. I also propose that an object akin to the characteristics of Laplace's Demon, in my paper a supercomputer which can process all data of everything at a single instant in time has the ability to both flawlessly predict the future and calculate the past.

Asymmetry theories about free will and moral responsibility are a recent development in the long history of the free will debate. To my knowledge, Kant commentators have not yet explored the possibility of an asymmetrical reconstruction of Kant's theory of freedom, and that will be my goal here. By "free will", I mean the sort of control we would need to be morally responsible for our actions. Kant's term for it is "transcendental freedom", and he refers to the attribution of (...) moral responsibility as "imputation". By "Kant's theory of freedom", I mean not only his theory of transcendental freedom and imputation, but also the various ways in which he draws on these ideas in his moral theory. (shrink)

Argues that acceptance of one’s place in the natural world involves an acceptance of free will. Free will is also necessary for the continuation of a social society in that we need to accept the doctrine in order to administer justice.

What I want to do in this essay is examine a notorious argument put forward by Galen Strawson. He advocates what he describes as an a priori argument against the possibility of ultimate (moral) responsibility. There have been many attempts at answering Strawson, but whether they have been successful is debatable. I attempt to employ Henri Bergson's approach to the free will debate and assess whether what he says has any purchase in terms of criticism of Strawson's position. I conclude (...) that Bergson's views offer a serious alternative in debates about free will. (shrink)

I have inquired as to what sort of knowledge humans need to make justifiable claims regarding free will. I defended the thesis that humans do not have the sort of knowledge which would allow them to make such claims. Adopting the view of mind based on cognitive science and Kant’s philosophy of mind, first I laid out the characteristics of that knowledge with the help of a simulation example I devised. Then, upon investigating the epistemic relations between the different sources (...) of knowledge and the agents of a system (such as the relation between the programmer and the simulated agents as well as god and humans), I claimed that knowledge bearing those characteristics cannot be accessible to human beings.

The following is a now popular argument for free will skepticism:1. If free will exists, then people make themselves.2. People do not make themselves.3. Thus, free will does not exist.It would make no sense to hold someone responsible, either for what he’s like or what he’s done, unless he has made himself. But no one makes himself. A person’s character is imposed upon him by Nature and others. To rebut, I intend to lean on common usage, according to which 2 (...) is false: the vernacular provides a clear sense in which we do make ourselves. It is the sense in which we speak of a cake being made from ingredients or a statue out of clay.Self-formation sufficient for a free will occurs along these lines. I shall discuss a Compatibilist and a Libertarian version of this project. (shrink)

Adopting meta-level Free Will Subjectivism is one among several ways to maintain that persons never experience moral freedom in their choices. The other ways of arguing against moral freedom I consider are presented by Saul Smilansky, Ted Honderich, Bruce Waller, Galen Strawson, and Derk Pereboom. In this paper, without arguing for the acceptance of free will subjectivism, I argue that subjectivism has some moral and theoretical advantages over its kindred theories.

Free will skepticism maintains that what we do, and the way we are, is ultimately the result of factors beyond our control and because of this we are never morally responsible for our actions in the basic desert sense—the sense that would make us truly deserving of praise and blame. In recent years, a number of contemporary philosophers have advanced and defended versions of free will skepticism, including Derk Pereboom (2001, 2014), Galen Strawson (2010), Neil Levy (2011), Bruce Waller (2011, (...) 2015), and myself (Caruso 2012, 2013, forthcoming). Critics, however, often complain that adopting such views would have dire consequences for ourselves, society, morality, meaning, and the law. They fear, for instance, that relinquishing belief in free will and basic desert moral responsibility would leave us unable to adequately deal with criminal behavior, increase anti-social conduct, and undermine meaning in life. -/- In response, free will skeptics argue that life without free will and basic desert moral responsibility would not be as destructive as many people believe (see, e.g., Pereboom 2001, 2014; Waller 2011, 2015; Caruso 2016, forthcoming). According to optimistic skeptics, prospects of finding meaning in life or of sustaining good interpersonal relationships, for instance, would not be threatened. And although retributivism and severe punishment, such as the death penalty, would be ruled out, incapacitation and rehabilitation programs would still be justified (see Pereboom 2001, 2013, 2014; Levy 2012; Caruso 2016; Pereboom and Caruso, forthcoming). In this paper, I attempt to extend this general optimism about the practical implications of free will skepticism to the question of creativity. -/- In Section I, I spell out the question of creativity and explain why it’s relevant to the problem of free will. In Section II, I identify three different conceptions of creativity and explain the practical concerns critics have with free will skepticism. In Section III, I distinguish between three different conceptions of moral responsibility and argue that at least two of them are consistent with free will skepticism. I further contend that forward-looking accounts of moral responsibility, which are perfectly consistent with free will skepticism, can justify calling agents to account for immoral behavior as well as providing encouragement for creative activities since these are important for moral and creative formation and development. I conclude in Section IV by arguing that relinquishing belief in free will and basic desert would not mean the death of creativity or our sense of achievement since important and realistic conceptions of both remain in place.

We are strongly inclined to believe in moral responsibility - the idea that certain human agents truly deserve moral praise or blame for some of their actions. However, recent philosophical discussion has put this natural belief under suspicion, and there are important reasons for thinking that moral responsibility is incompatible with both determinism and indeterminism, therefore potentially rendering it an impossibility. Presenting the major arguments for scepticism about moral responsibility, and subjecting them to sustained and penetrating critical analysis, _Moral Responsibility_ (...) lays out the intricate dialectic involved in these issues in a helpful and accessible way. A well-written and lively account, the book then goes on to suggest a way in which scepticism can be avoided, arguing that excessive pre-eminence given to the will might lie at its root. Offering an alternative to this scepticism, Carlos Moya shows how a cognitive approach to moral responsibility that stresses the importance of belief would rescue our natural and centrally important faith in the reality of moral responsibility.

What are the types of action at issue in the free will and moral responsibility debate? Are the neuroscientists who make claims about free will and moral responsibility studying those types of action? If not, can the existing paradigm in the field be modified to study those types of action? This paper outlines some claims made by neuroscientists about the inefficacy of conscious intentions and the implications of this inefficacy for the existence of free will. It argues that, typically, the (...) types of actions at issue in the philosophical literature require proximal or distal conscious decisions and have the right kind of connection to reasons. It points out that neuroscientists are not studying this class of actions, as their studies focus on simple commanded actions (e.g., finger flex) and simple Buridan choices (e.g., push the left or right button). Finally, it argues that neuroscience already has the resources to study the types of action relevant for free will and moral responsibility and outlines two experiments which focus on skilled actions and moral choices that could be run using the available technology.

Hard determinists hold that we never have alternative possibilities of action—that we only can do what we actually do. This means that if hard determinists accept the “ought implies can” principle, they mustaccept that it is never the case that we ought to do anything we do not do. In other words, they must reject the view that there can be “ought”- based moral reasons to do things we do not do. Hard determinists who wish to accommodate moral reasons to (...) do things we do not do can instead appeal to Humean moral reasons that are based on desires to be virtuous. Moral reasons grounded on desires to be virtuous do not depend on our being able to act on those reasons in the way that “ought”-based moral reasons do. (shrink)

In this paper, I present a novel argument for scepticism about moral responsibility. Unlike traditional arguments, this argument doesn’t depend on contingent empirical claims about the truth or falsity of causal determinism. Rather, it is argued that the conceptual conditions of responsibility are jointly incompatible. In short, when an agent is responsible for an action, it must be true both that the action was non-accidental, and that it was open to the agent not to perform that action. However, as I (...) argue, an action is only non-accidental in those cases where it isn’t open to the agent not to perform it. (shrink)

Libertarians like Robert Kane believe that indeterminism is necessary for free will. They think this in part because they hold both that my being the ultimate cause of at least part of myself is necessary for free will and that indeterminism is necessary for this "ultimate self-causation". But seductive and intuitive as this "USC Libertarianism" may sound, it is untenable. In the end, no metaphysically coherent conception of ultimate self-causation is available. So the basic intuition motivating the USC Libertarian is (...) ultimately impossible to fulfill. (shrink)

Spinoza’s moral philosophy is trending. This is the fourth book written in English in six years devoted to various aspects of it; that may not qualify as viral, but it is progress. The volume’s five essays cover moral responsibility, akrasia, moral realism, and Spinoza’s model of human nature: the free man. Hence its subtitle is misleading. There is nothing uniquely contemporary about the issues discussed, as is evident from the essays themselves. Also, the moral problems are not the type one (...) might expect. You will not find an analysis of Spinoza’s position on the moral status of non-human animals, for example. What you will find is an effort to bring Spinoza into contemporary debates.

The purpose of this paper is to evaluate Pereboom’s attempt to use his quarantine analogy to justify his theory of crime prevention and the use of preventative detainment in place of punishment. Specifically, I will examine the quality of the analogy drawn between quarantining and preventative detainment and its ability to provide acceptable practical conclusions on the nature of preventative detainment. First, I will argue that the analogy is promising because the two practices share appropriate and relevant similarities. And since (...) the analogy is shown to be promising, I agree with Pereboom that the justification of quarantining can be transferred to preventative detainment. In the second chapter, I will discuss feasible approaches to justifying quarantining. After examining two plausible and contemporary ways of determining when quarantining is just, I will dedicate the third chapter of this paper to applying these justifications to preventative detainment and assess the acceptability of these applications. In doing so, I will discuss the problems that arise when contemporary quarantine justifications are applied to preventative detainment. However, I will argue that these problems are not the result of some flaw in the analogy, but rather stem from a reluctance to accept free will skepticism in general. Thus, if free will skepticism holds, once an appropriate justification of quarantining is found, it can be used to justify the analogous practice of preventative detainment. (shrink)
