By means of the Rollback Argument, this paper argues that metaphysically robust probabilities are incompatible with a kind of control which can ensure that free actions are not a matter of chance. Our main objection to those (typically agent-causal) theories which both attribute a kind of control to agents that eliminates the role of chance concerning free actions and ascribe probabilities to options of decisions is that metaphysically robust probabilities should be posited only if they can have a (...) metaphysical explanatory role but probabilities can explain anything only if chance has a role. First, we reconstruct the Rollback Argument. Second, we criticize the standard ways of reconciling non-chancy control with metaphysically robust probabilities. Finally, we respond to those worries that are related to the thought experiment of the Rollback Argument. (shrink)

Seth Shabo has presented a new argument that attempts to codify familiar worries about indeterminism, luck, and control. His ‘Assimilation Argument’ contends that libertarians cannot distinguish overtly randomized outcomes from exercises of free will. Shabo claims that the argument possesses advantages over the Mind Argument and Rollback Argument, which also purport to establish that indeterminism is incompatible with free will. I argue first that the Assimilation Argument presents no new challenges over and above (...) those presented by the Rollback Argument, and second that the Rollback Argument itself neither presents a deep challenge to, nor raises the cost of, accepting libertarianism.

결정론자는 행위자의 선택이 인과적으로 결정되어 있다고 믿는 반면 자유주의자는 그렇지 않다고 믿는다. 이 글은 자유주의에 대한 한 가지 비판을 다룬다. 세스 샤보(S. Shabo)는 「자유의지와 미스터리: 『마인드』주장을 넘어서」에서 반 인와겐(P. van Inwagen)의 역행 논증을 정교화하면서 자유주의에 대한 반론을 펼친다. 샤보는 어떻게 행위자가 인과적으로 비결정적인 두 가지 가능한 미래상황을 하나의 실제적 미래상황이 되도록 이끄는 결정력(the power to settle)을 가질 수 있는지에 대해 자유주의자가 설명해야 한다고 주장한다. 필자는 이 결정력에 대한 샤보의 비판을 반박하며 어떤 차원에서 행위자가 그것을 소유할 수 있는지에 대한 해명을 시도한다.BR (...) 필자는 2장과 3장에서 역행 논증과 더불어 결정력에 대한 샤보의 논증을 제시한다. 4장에서는 자유주의자에게 결정력을 설명하도록 요구하는 샤보의 주장이 왜 부당한지를 해명한다. 5장에서는 행위자의 선택이 어떤 점에서 행위자 자신에게 달려 있는 사안일 수 있는지에 대한 해명을 시도한다. 6장에서 필자는 역행 논증의 핵심을 재정립하고 그러한 재정립 후에도 여전히 그것이 자유주의를 무력화하기에는 역부족임을 논증한다.

The ‘rollback argument,’ pioneered by Peter van Inwagen, purports to show that indeterminism in any form is incompatible with free will. The argument has two major premises: the first claims that certain facts about chances obtain in a certain kind of hypothetical situation, and the second that these facts entail that some actual act is not free. Since the publication of the rollback argument, the second claim has been vehemently debated, but everyone seems to have (...) taken the first claim for granted. Nevertheless, the first claim is totally unjustified. Even if we accept the second claim, therefore, the argument gives us no reason to think that free will and indeterminism are incompatible. Furthermore, seeing where the rollback argument goes wrong illuminates how a certain kind of incompatibilist, the ‘chance-incompatibilist,’ ought to think about free will and chance, and points to a possibility for free will that has remained largely unexplored.

It is widely assumed that candidates for free, undetermined choices must have objective probabilities prior to their performance. Indeed although this premise figures prominently in a widely discussed argument against libertarianism, few libertarians have called it into question. In this article, I will investigate whether libertarians ought to reject it. I will conclude that doing so should not be tempting to event-causal libertarians or most agent-causal ones, because the added costs outweigh the benefits.

The Assimilation Argument purports to show that libertarians cannot plausibly distinguish supposed exercises of free will from random outcomes that nobody would count as exercises of free will. If this argument is sound, libertarians should either abandon their position or else concede that free will is a mystery. Drawing on a parallel with the Manipulation Argument against compatibilism, Christopher Franklin has recently contended that the Assimilation Argument is unsound. Here I defend the Assimilation Argument and (...) the Rollback Argument, a second challenge to libertarianism that Franklin rejects. My aim in doing so is to underscore the force of these challenges, and thereby to resist what appears to be an emerging trend in the literature. By not coming to grips with the kind of power that libertarians must secure, many writers have recently downplayed or dismissed the pressing worry for libertarianism. (shrink)

Rollback arguments focus on long sequences of actions with identical initial conditions in order to explicate the luck problem that indeterminism poses for libertarian free will theories (i.e. the problem that indeterministic actions appear arbitrary in a free-will undermining way). In this paper, I propose a rollback argument for probability incompatibilism, i.e. for the thesis that free will is incompatible with all world-states being governed by objective probabilities. Other than the most prominently discussed rollback arguments, this (...) argument explicitly focusses on the ability to act otherwise. It argues that the negligible probability of the relative frequencies in overall rollback patterns being relevantly different indicates that even the ability to act otherwise with regard to individual actions is not free-will enabling. My proposed argument provides probability incompatibilists with a tool to argue against a classical event-causal response to the luck problem, while it can still motivate an agent-causal response to it. (shrink)

In this paper, I articulate an argument for incompatibilism about moral responsibility and determinism. My argument comes in the form of an extended story, modeled loosely on Peter van Inwagen’s “rollback argument” scenario. I thus call it “the replication argument.” As I aim to bring out, though the argument is inspired by so-called “manipulation” and “original design” arguments, the argument is not a version of either such argument—and plausibly has advantages over both. (...) The result, I believe, is a more convincing incompatibilist argument than those we have considered previously. (shrink)

Reliabilists accept the possibility of basic knowledge—knowledge that p in virtue of the reliability of some belief-producing process r without antecedent knowledge that r is reliable. Cohen (Philos Phenomenol Res 65:309–329, 2002 , Philos Phenomenol Res 70:417–430, 2005 ) and Vogel (J Philos 97:602–623, 2000 , J Philos 105:518–539, 2008 ) have argued that one can bootstrap knowledge that r is reliable from basic knowledge. This paper provides a diagnosis of epistemic bootstrapping, and then shows that recent attempts at embracing (...) bootstrapped knowledge are found wanting. Instead it is argued that such arguments are afflicted by a novel kind of generalized epistemic circularity. The ensuing view is defended against various objections, and an explanation of the source of that circularity is offered. (shrink)

In this paper I seek to defend libertarianism about free will and moral responsibility against two well-known arguments: the luck argument and the Mind argument. Both of these arguments purport to show that indeterminism is incompatible with the degree of control necessary for free will and moral responsibility. I begin the discussion by elaborating these arguments, clarifying important features of my preferred version of libertarianism—features that will be central to an adequate response to the arguments—and showing why a (...) strategy of reconciliation (often referred to as “deliberative libertarianism”) will not work. I then consider four formulations of the luck argument and find them all wanting. This discussion will place us in a favorable position to understand why the Mind argument also fails. (shrink)

Among challenges to libertarians, the _Mind_ Argument has loomed large. Believing that this challenge cannot be met, Peter van Inwagen, a libertarian, concludes that free will is a mystery. Recently, the _Mind_ Argument has drawn a number of criticisms. Here I seek to add to its woes. Quite apart from its other problems, I argue, the _Mind_ Argument does a poor job of isolating the important concern for libertarians that it raises. Once this concern has been clarified, (...) however, another argument serves to renew the challenge. The Assimilation Argument challenges libertarians to explain how ostensible exercises of free will are relevantly different from other causally undetermined outcomes, outcomes that nobody would count as exercises of free will. In particular, libertarians must explain how agents can have the power to settle which of two causally possible futures becomes the actual future. This will require them to distinguish cases where this power is supposedly present from similar cases where it’s clearly absent. (shrink)

Libertarianism appears to be incoherent, because free will appears to be incompatible with indeterminism. In support of this claim, van Inwagen offered an argument that is now known as the “rollback argument”. In a recent reply, Lara Buchak has argued that the underlying thought experiment fails to support the first of two key premises. On her view, this points to an unexplored alternative in the free will debate, which she calls “chance-incompatibilism”. I will argue that the (...) class='Hi'>rollback thought experiment does support the second key premise of the argument, and, more importantly, that libertarianism is committed to the first premise for independent reasons concerning the relationship between the normative and causal strength of the agent’s reasons. The upshot will be that chance-incompatibilism is not a promising new alternative in the free will debate, and we will see that the debate around those issues can benefit from more attention to the role of the agent’s reasons for action. (shrink)

Peter van Inwagen famously offers a version of the luck objection to libertarianism called the ‘Rollback Argument.’ It involves a thought experiment in which God repeatedly rolls time backward to provide an agent with many opportunities to act in the same circumstance. Because the agent has the kind of freedom that affords her alternative possibilities at the moment of choice, she performs different actions in some of these opportunities. The upshot is that whichever action she performs in the (...) actual-sequence is intuitively a matter of mere chance. I explore a new response to the Rollback Argument. If there are true counterfactuals of libertarian freedom, then the agent performs the same action each time she is placed in the same circumstance, because that is what she would freely do in that circumstance. This response appears to negate the chancy intuition. Ultimately, however, I argue that this new response is unsuccessful, because there is a variant of the Rollback Argument that presents the same basic challenge to the libertarian on the assumption that there are true counterfactuals of libertarian freedom. Thus, true counterfactuals of libertarian freedom do not provide the libertarian with a solution to the Rollback Argument. (shrink)

Abstract -/- Libertarians typically believe that we are morally responsible for the choices (or decisions) we make only if those choices are free, and our choices are free only if they are neither caused nor nomically necessitated by antecedent events. Recently, there have been a number of attempts by philosophers to refute libertarianism by arguing that because a libertarianly free decision (choice) is both causally and nomically undetermined, which decision an agent makes in a deliberative situation is a matter of (...) luck, which implies (due to the way these philosophers use 'luck') that the agent does not have control over which decision he makes. This argument has been dubbed "the Argument from Luck" or "the Luck Objection" against libertarianism – henceforth 'LO'. In this paper, we examine some versions of LO as reflected in the works of Alfred Mele (2006), Neil Levy (2011), and Peter van Inwagen (2000, 2011). We argue that libertarians have nothing to fear from LO. Deep down the objection reflects a failure, on the part of its proponents, really to come to grips with the libertarian position. (shrink)

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

I here sketch a reply to Peter van Inwagen’s Rollback Argument, which suggests that libertarian accounts of free agency are beset by problems involving luck. Van Inwagen imagines an indeterministic agent whose universe is repeatedly ‘rolled back’ by God to the time of her choice. Since the agent’s choice is indeterministic, her choices are sometimes di erent in the imaginary rollback scenarios. I show that although this is true, this need not impair her control over what she (...) does. I develop an account of when and why the fact that an agent would choose di erently impairs control, which provides a novel response to the Rollback Argument. (shrink)

In the contemporary debate on free will, most philosophers assume that the defense of libertarianism implies the defense of the notion of alternative possibilities. This article discusses this presupposition by showing that it is possible to build a libertarianism without alternative possibilities, apparently more robust than libertarianism with alternative possibilities. Inspired by Bergson, this nonclassical libertarianism challenges the idea that all causation implies the actualization of a predetermined possibility (an idea shared by determinism and classical libertarianism). Moreover, it challenges the (...) idea that free will is a mere choice between prefixed possibilities: for this libertarianism, free will is the result of a creative process of the mind—an entirely causal process whose outcome is not, however, predetermined. This nonclassical libertarianism describes the process of forming a will in a more realistic way than classical libertarianism does. Furthermore, it is not threatened by the problem of chance.

I argue against motivational internalism. First I recharacterise the issue over moral motivation. Second I describe the indifference argument against motivation internalism. Third I consider appeals to irrationality that are often made in the face of this argument, and I show that they are ineffective. Lastly, I draw the motivational externalist conclusion and reflect on the nature of the issue.

It shall be examined how anti-physicalist arguments give rise to the tension between those aspects of our everyday life and the thesis of physicalism. The debate over the subjective character of consciousness, or as it is sometimes called: “the hard problem of consciousness”, is considered to be the greatest challenge to physicalism. Many philosophers posit this as a matter that cannot be solved, regardless of scientific progress, for it is beyond the scope of what science can find out about the (...) world. If they are correct, the consequence is that the idea of physicalism itself fails. The paper is divided in two parts. For the first part we will deal with Chalmers’ version of the conceivability argument as well as the semantic apparatus of the two-dimensional framework required to make the appropriate link between conceivability and possibility. At the end of this we shall take a look at Kripke’s version of the conceivability argument against physicalism. (shrink)

According to the indispensability argument, the fact that we quantify over numbers, sets and functions in our best scientific theories gives us reason for believing that such objects exist. I examine a strategy to dispense with such quantification by simply replacing any given platonistic theory by the set of sentences in the nominalist vocabulary it logically entails. I argue that, as a strategy, this response fails: for there is no guarantee that the nominalist world that go beyond the set (...) of sentences in the nominalist language such theories entail. However, I argue that what such theories show is that mathematics can enable us to express possibilities about the concrete world that may not be expressible in nominalistically acceptable language. While I grant that this may make quantification over abstracta indispensable, I deny that such indispensability is a reason for accepting them into our ontology. I urge that the nominalist should be allowed to quantify over abstracta whilst denying their existence and I explain how this apparently contradictory practice (a practice I call 'weaseling') is in fact coherent, unproblematic and rational. Finally, I examine the view that platonistic theories are simpler or more attractive than their nominalistic reformulations, and thus that abstract ought to be accepted into our ontology for the same sorts of reasons as other theoretical objects. I argue that, at least in the case of numbers, functions and sets, such arguments misunderstand the kind of simplicity and attractiveness we seek. (shrink)

A Theory of Argument is an advanced textbook intended for students in philosophy, communications studies and linguistics who have completed at least one course in argumentation theory, information logic, critical thinking or formal logic. Containing nearly 400 exercises, Mark Vorobej develops a novel approach to argument interpretation and evaluation. One of the key themes of the book is that we cannot succeed in distinguishing good argument from bad arguments until we learn to listen carefully to others. Part (...) I develops a relativistic account of argument cogency that allows for rational disagreement. Part II offers a comprehensive and rigorous account of argument diagramming. Hybrid arguments are contrasted with linked and convergent arguments, and a novel technique is introduced for graphically recording disagreements with authorial claims. (shrink)

The moral argument for the existence of God is really a family of arguments. What they have in common is Kant’s insistence that philosophical theology proceed by drawing out the presuppositions of moral reasoning. Kant’s own favorite version of the argument is widely rejected today. Kant maintained that the summum bonum, the perfect unison of virtue and happiness, is the aim of rational action. Because it ought to be achieved it is possible, as the ought implies the ability (...) to bring it about. The moral faith is that God’s existence and human immortality enable continued moral progress after death and the enjoying of happiness appropriate to it, thus making the arrival at the summum bonum possible. Kant also urged that the categorical commands of the moral conscience suggested the existence of a cosmic lawgiver and commander, and there are a number of nineteenth-century arguments which proceed along those lines.

In recent years, a new argument in favor of Donnellan’s (Philos Rev 77: 281–304, 1966) semantic distinction between attributive and referential descriptions has been proposed by Michael Devitt and Marga Reimer. This argument is based on two empirical premises concerning regularity of use and processing ease. This paper is an attempt to demonstrate (a) that these empirical observations are dubious and fail to license the conclusion of the argument and (b) that if the argument were sound, (...) it would severely overgenerate. The general lesson of the paper is that empirical observations about (a) how frequent an expression E is used to mean M and (b) how easy and fast M is processed cannot be taken to provide reliable evidence about the lexically encoded semantic properties of E.

Russ Schafer-Landau’s ‘Moral judgement and normative reasons’ is admirably clear and to the point (Schafer-Landau 1999). He presents his own version of the argument for the practicality requirement on moral judgement – that is, for the claim that those who have moral beliefs are either motivated or practically irrational – that I gave in The Moral Problem (Smith 1994), and he then proceeds to identify several crucial problems. In what follows I begin by making some comments about his presentation (...) of the argument. I then confront the problems. (shrink)
