What are the folk-conceptual connections between free will and consciousness? In this paper I present results which indicate that consciousness plays central roles in folk conceptions of free will. When conscious states cause behavior, people tend to judge that the agent acted freely. And when unconscious states cause behavior, people tend to judge that the agent did not act freely. Further, these studies contribute to recent experimental work on folk philosophical affiliation, which analyzes folk responses to determine whether folk views (...) are consistent with the view that free will and determinism are incompatible (incompatibilism) or with the opposite view (compatibilism). Conscious causation of behavior tends to elicit pro-free will judgments, even when the causation takes place deterministically. Thus, when controlling for consciousness, many folk seem to be compatibilists. However, participants who disagree with the deterministic or cognitive scientific descriptions given of human behavior tend to give incompatibilist responses. (shrink)

This article is my contribution to an author-meets-critics session on Daniel Dennett’s Freedom Evolves (Viking, 2003) at the 2004 meetings of the American Philosophical Association – Pacific Division. Dennett criticizes a view I defend in Autonomous Agents (Oxford University Press, 1995) about the importance of agents’ histories for autonomy, freedom, and moral responsibility and defends a competing view. Our disagreement on this issue is the major focus of this article. Additional topics are manipulation, avoidance, and avoidability.

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)

This article distinguishes among and examines three different kinds of argument for the thesis that moral responsibility and free action are each incompatible with the truth of determinism: straight manipulation arguments; manipulation arguments to the best explanation; and original-design arguments. Structural and methodological matters are the primary focus.

To what extent should an analysis of an agent’s being morally responsible for an action that he performed—especially a compatibilist analysis of this—be sensitive to the agent’s history? In this article, I give the issue a clearer focus than it tends to have in the literature, I lay some groundwork for an attempt to answer the question, and I motivate a partial but detailed answer.

Recent work by Alfred Mele, Romy Jaster and Chandra Sripada recognizes that abilities come in degrees of fallibility. The rough idea is that abilities are often not surefire. They are liable to fail. The more liable an ability is to fail, the more fallible it is. Fallibility is plausibly significant for addiction, responsibility, and normative theorizing. However, we lack an adequate account of what fallibility consists in. This article addresses that problem. Perhaps the most natural approach is to say (roughly) (...) the fallibility of your ability to F is the proportion of scenarios in which you do not F, among those in which you try to F. I argue that this approach (in all plausible versions) is mistaken. I then introduce the notion of an action’s “fragility,” and propose that we use that new notion to understand fallibility.

Many philosophical discussions hinge on the concept of knowability. For example, there is a blooming literature on the so-called paradox of knowability. How to understand this notion, however? In this paper, we examine several approaches to the notion: the naive approach to take knowability as the possibility to know, the counterfactual approach endorsed by Edgington (1985) and Schlöder (2019) , approaches based on the notion of a capacity or ability to know (Fara 2010, Humphreys 2011), and finally, approaches that make (...) use of the resources of dynamic epistemic logic (van Benthem 2004, Holliday 2017). (shrink)

A minimal constraint on normative reasons seems to be that if some fact is a reason for an agent to φ (act, believe, or feel), the agent could come to know that fact. This constraint is threatened by a well-known type of counterexamples. Self-effacing reasons are facts that intuitively constitute reasons for an agent to φ, but that if they were to become known, they would cease to be reasons for that agent. The challenge posed by self-effacing reasons bears important (...) structural similarities with a range of epistemic paradoxes, most notably the Knowability Paradox. In this article, we investigate the similarities and differences between the two arguments. Moreover, we assess whether some of the approaches to the Knowability Paradox could help solve the challenge posed by self-effacing reasons. We argue that at least two popular approaches to the paradox can be turned into promising strategies for addressing the self-effacing reasons problem. (shrink)

Abilities, in contrast to mere dispositions, propensities, or tendencies, abilities seem to be features of agents that put the agent herself in control. But what is the distinguishing feature of abilities vis‐à‐vis other kinds of powers? Our aim in this paper is to point, in answer to this question, to a crucial feature of abilities that existing accounts have tended to neglect: their adaptivity. Adaptivity is a feature of how abilities are exercised. The main reason for its relative neglect has (...) been that most extant accounts have focused solely on whether abilities are exercised successfully in certain possible situations and have mostly understood the exercise of an ability in terms of complete successful performance. We begin by pointing out two aspects of abilities with regard to which current accounts seem (at best) incomplete: control and exercise. We then introduce adaptivity as we understand it, and end by putting it to work in developing a fuller understanding of abilities that does better than current accounts. (shrink)

In this paper, I challenge the Consequence Argument for Incompatibilism by arguing that the inference principle it relies upon is not well motivated. The sorts of non-question-begging instances that might be offered in support of it fall short.

Decision-making capacity (DMC) plays an important role in clinical practice—determining, on the basis of a patient’s decisional abilities, whether they are entitled to make their own medical decisions or whether a surrogate must be secured to participate in decisions on their behalf. As a result, it’s critical that we get things right—that our conceptual framework be well-suited to the task of helping practitioners systematically sort through the relevant ethical considerations in a way that reliably and transparently delivers correct verdicts about (...) who should and should not have the authority to make their own medical decisions. Unfortunately, however, the standard approach to DMC does not get things right. It is of virtually no help in identifying and clarifying the relevant ethical considerations. And, embedded in the prevailing anti-paternalist paradigm, DMC assessments obfuscate and distort the underlying ethical justification for granting or withholding decisional authority. Here, we describe the core commitments of the standard approach to DMC and then highlight three problems with it. We then argue that these problems are significant enough that they call for more than merely tinkering and fine tuning—variations of the standard approach cannot adequately address them. Instead, we should ditch DMC. (shrink)

ABSTRACT It’s often assumed, especially in discussions of free will and moral responsibility, that unavoidable actions are possible. In recent years, however, several philosophers have questioned that assumption. Their views are considered here, and the possibility of unavoidable actions is defended and then applied to issues in action theory and in the literature on moral responsibility.

The philosophy of time travel is a sub-field of metaphysics – the study of what there is and what things are like – that considers questions about the possibility of time travel and what a world in which time travel is possible looks like. These questions range from whether time travel is actually possible, to how time travellers can act in the past or future. This thesis delves into a particularly interesting, yet historically undertreated theme: the abilities of time travellers (...) and relatedly their freedom as well. The abilities and freedom of time travellers has been the source of a lot of recent discussion with some polarising views. The minority (which includes Lewis (1976), but also Ted Sider (2002)) argue for the affirmative – that time travellers are free and have the same (or perhaps more) abilities as non-time travellers. The majority (which includes Kadri Vihvelin (1996), Michael Rea (2005), Stephanie Rennick (2015), Alison Fernandes (2020), amongst others) argue for the negative, that time travellers do not have exactly the same freedoms and abilities as non-time travellers. I think that it is a mistake to be so pessimistic about the abilities and freedom of time travellers. I treat concerns about the freedom of time travellers and concerns about the abilities of time travellers as two sides of the same coin. Therefore, in what follows, I argue for two related conclusions. First, I argue that time travellers have all sorts of abilities. Second, I argue that time travellers are just as free as non-time travellers. In arguing for these conclusions, I first produce a novel analysis of ability which reveals important details about how abilities track inputs rather than outputs. Second, I use this new analysis of ability to present a new compatibilist account of free will. If I am right in arguing positively for the abilities and freedoms of time travellers, then this has large implications for both the current time travel discourse and the general debate surrounding freedom. Significantly, I am arguing against some prominent views about time travel and in suggesting that these views are mistaken, I am presenting new ideas about ability and freedom: specifically, that time travellers have the ability and are free to do impossible things.

Intentional action is, in some sense, non-accidental, and one common way action theorists have attempted to explain this is with reference to control. The idea, in short, is that intentional action implicates control, and control precludes accidentality. But in virtue of what, exactly, would exercising control over an action suffice to make it non-accidental in whatever sense is required for the action to be intentional? One interesting and prima facie plausible idea that we wish to explore in this paper is (...) that control is non-accidental in virtue of requiring knowledge—either knowledge-that or knowledge-how (e.g., Beddor and Pavese 2021; cf., Setiya 2008; 2012 and Habgood-Coote 2018). We review in detail some key recent work defending such knowledge-centric theories of control, and we show that none of these accounts holds water. We conclude with some discussion about how control opposes the sort of luck intentional action excludes without doing so by requiring knowledge (that- or how). (shrink)

What is it to be able to intend to do something? At the end of her ground-breaking book, Agents’ Abilities, Romy Jaster identifies this question as a topic for future research. This article tackles the question from within the framework Jaster assembled for understanding abilities. The discussion takes place in two different spheres: intentions formed in acts of deciding, and intentions not so formed. The gradability of abilities has an important place in Jaster’s framework, and it is explained how abilities (...) to acquire intentions of these two kinds -- including both general and specific abilities—can come in degrees, as she conceives of degrees of ability. Although Jaster “sympathize[s] with the idea that having an ability to intend to [A] is a matter of intending to [A] in a sufficient proportion of the relevant possible situations in which there is an overriding reason to intend to [A],” an alternative to this idea is developed.

Philosophers often talk as though each ability is held by exactly one agent. This paper begins by arguing that abilities can be held by groups of agents, where the group is not an agent. I provide a new argument for—and a new analysis of—non-agentive groups’ abilities. I then provide a new argument that, surprisingly, obligations are different: non-agentive groups cannot bear obligations, at least not if those groups are large-scale such as ‘humanity’ or ‘carbon emitters.’ This pair of conclusions is (...) important, since philosophers who endorse large-scale non-agentive groups’ abilities almost universally endorse their obligations. More importantly, the twin arguments (one for abilities, one against obligations) make the following novel contribution: abilities imply agency-involving explanations, while obligations imply action-guidance. This general conclusion should be of interest beyond social ontology. (shrink)

I distinguish two ways an ability might be general: (i) an ability might be general in that its possession doesn't entail the possession of an opportunity; (ii) an ability might be general in virtue of pertaining to a wide range of circumstances. I argue that these two types of generality – I refer to them with the terms ‘general’ and ‘generic’, respectively – produce two orthogonal distinctions among abilities. I show that the two types of generality are sometimes run together (...) by those writing on free will and argue that both types of generality are relevant to understanding the modality of abilities. (shrink)

Haji argues that determinism threatens deontic morality, not via a threat to moral responsibility, but directly, because of the principle that ‘ought’ implies ‘can’. Haji’s argument requires not only that we embrace an ‘ought’ implies ‘can’ principle, but also that we adopt the principle that ‘ought’ implies ‘able not to’. I argue that we have little reason to adopt the latter principle, and examine whether deontic morality might be destroyed on the basis of the more commonly embraced ‘ought’ implies ‘can’ (...) principle alone. I argue that despite what look like initially compelling reasons why we might suppose that this weaker conclusion is similarly destructive to deontic morality, we actually have good reason to doubt that it has any practical relevance for moral deliberation at all. (shrink)

The actions of able agents are often reliably successful. I argue that their success may be modally robust along two dimensions. The first dimension helps distinguish the exercise of abilities, which requires local control, from lucky success. The second concerns the global availability of acts: agents with the ability to φ can φ across a variety of circumstances. I introduce a framework that captures the two dimensions and their interaction, and show how it bears on a disagreement about the modal (...) force the robustness of ability requires: while local control involves a kind of local necessity, global availability does not. (shrink)

Fodor argued that learning a concept by hypothesis testing would involve an impossible circularity. I show that Fodor's argument implicitly relies on the assumption that actually φ-ing entails an ability to φ. But this assumption is false in cases of φ-ing by luck, and just such luck is involved in testing hypotheses with the kinds of generative random sampling methods that many cognitive scientists take our minds to use. Concepts thus can be learned by hypothesis testing without circularity, and it (...) is plausible that this is how humans in fact acquire at least some of their concepts. (shrink)

This paper warns of two threats to moral responsibility that arise when accounting for omissions, given some plausible assumptions about how abilities are related to responsibility. The first problem threatens the legitimacy of our being responsible by expanding the preexisting tension that luck famously raises for moral responsibility. The second threat to moral responsibility challenges the legitimacy of our practices of holding responsible. Holding others responsible for their omissions requires us to bridge an epistemic gap that does not arise when (...) holding others responsible for their actions—one that we might often fail to cross. (shrink)

Epistemologists often appeal to the idea that a normative theory must provide useful, usable, guidance to argue for one normative epistemology over another. I argue that this is a mistake. Guidance considerations have no role to play in theory choice in epistemology. I show how this has implications for debates about the possibility and scope of epistemic dilemmas, the legitimacy of idealisation in Bayesian epistemology, uniqueness versus permissivism, sharp versus mushy credences, and internalism versus externalism.

The Shape of Agency offers interlinked explanations of the basic building blocks of agency, as well as its exemplary instances. The first part offers accounts of a collection of related phenomena that have long troubled philosophers of action: control over behaviour, non-deviant causation, and intentional action. These accounts build on earlier work in the causalist tradition, and undermine the claims made by many that causalism cannot offer a satisfying account of non-deviant causation, and therefore fails as an account of intentional (...) action. The second part turns to modes of agentive excellence—ways that agents display quality of form—providing a novel account of skill, including an account of the ways that agents display more or less skill. Shepherd discusses the role of knowledge in skill, and concludes that while knowledge is often important, it is inessential. This leads to a discussion of the way that knowledge of action and knowledge of how to act informs action execution. Knowledgeable action includes a unique epistemic underpinning: in knowledgeable action, the agent has authoritative knowledge of what she is doing and how she is doing it when and because she is poised to control her action by way of practical reasoning.

Many important harms result in large part from our collective omissions, such as harms from our omissions to stop climate change and famines. Accounting for responsibility for collective omissions turns out to be particularly challenging. It is hard to see how an individual contributes anything to a collective omission to prevent harm if she couldn’t have made a difference to that harm on her own. Some groups are able to prevent such harms, but it is highly contentious whether groups can (...) be loci of responsibility. This paper takes an existing and plausible framework of moral responsibility—one based on abilities—and scales it up to accommodate responsibility for collective omissions. This centrally involves identifying what the relevant collective abilities are and how they work. One significant benefit of this approach is that we can do this while remaining neutral on the debates about collective agency and collective responsibility by showing how individualist and collectivist versions of the theory work. Finally, I explore several further upshots of the scaled-up ability-based account, including that degrees of responsibility can be cashed out in terms of strengths of the relevant abilities, which has both theoretical and applied implications.

This paper offers a new argument in favour of experiential pluralism about visual experience – the view that the nature of successful visual experience is different from the nature of unsuccessful visual experience. The argument appeals to the role of experience in explaining possession of ordinary abilities. In addition, the paper makes a methodological point about philosophical debates concerning the nature of perceptual experience: whether a given view about the nature of experience amounts to an interesting and substantive thesis about (...) our own minds depends on the significance of the psychological or mental kind claim made by it. This means that an adequate defence of a given view of the nature of experience must include articulation of the latter's significance qua psychological or mental kind. The argument advanced provides the material to meet this demand. In turn, this constitutes further support for the argument itself. (shrink)

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

A bi-level account of trust is developed and defended, one with relevance in ethics as well as epistemology. The proposed account of trust—on which trusting is modelled within a virtue-theoretic framework as a performance-type with an aim—distinguishes between two distinct levels of trust, apt and convictive, that take us beyond previous assessments of its nature, value, and relationship to risk assessment. While Sosa, in particular, has shown how a performance normativity model may be fruitfully applied to belief, my objective is (...) to apply this kind of model in a novel and principled way to trust. I conclude by outlining some of the key advantages of the performance-theoretic bi-level account of trust defended over more traditional univocal proposals. (shrink)

In this paper, I demonstrate that Kant's commitment to an asymmetry between the control conditions for praise and blame is explained by his endorsement of the principle Ought Implies Can (OIC). I argue that Kant accepts only a relatively weak version of OIC and that he is hence committed only to a relatively weak requirement of alternate possibilities for moral blame. This suggests that whether we are transcendentally free is irrelevant to questions about moral permissibility and moral blameworthiness.

Talents often play a significant role in our personal and social lives. For example, our talents may shape the choices we make and the goods that we value, making them central to the creation of a meaningful life. Differences in the level of talents also affect how social institutions are structured, and how social goods and resources are distributed. Despite their normative importance, it is surprising that talents have not yet received substantial philosophical analysis in their own right. As a (...) result, the current literature is rife with conceptual ambiguity: a talent is referred to as all of a skill, potential, ability, capacity, endowment, and a natural gift. In response to this confusion, in this paper I develop an account of what a talent is, based on the debate concerning the metaphysics of ability and dispositions. I argue for a position that I call ‘talent dispositionalism’: S has a talent for skill A in circumstances C iff S has the general disposition to excellently develop and maintain A when, in circumstances C, she tries to excellently develop and maintain A. On this account, a talent is not the skill itself, but a general iterated ability for the excellent development and up-keep of a particular skill, constituted by an agent’s dispositional properties. I defend the account against four objections usually levelled against traditional dispositionalist theories of ability, and highlight some ways the account may influence debates in other areas of philosophical inquiry. (shrink)

Two principles regarding agents' specific ability are proposed. The first claims that ordinary agents always lack the ability to do otherwise in the past, while the second principle observes that it is at least possible for some agent to have the ability to perform some action in the past. These two principles further give rise to three desiderata for a true account of ability. Two accounts of ability in the literature—the conditional analysis and the dispositional account—are then examined but they (...) both fail to meet the desiderata simultaneously. A modal principle of ability is motivated at the end. (shrink)

Externalists about epistemic justification have long emphasized the connection between truth and justification, with this coupling finding explicit expression in process reliabilism. Process reliabilism, however, faces a number of severe difficulties, leading disenchanted process reliabilists to find a new theoretical home. The conceptual flag under which such epistemologists have preferred to gather is that of dispositions. Just as reliabilism is determined by the frequency of a particular outcome, making it possible to characterize justification in terms of a particular relationship to (...) truth, dispositions are accompanied by concrete, worldly manifestations. By taking true beliefs as the result, not of certain processes but of particular dispositions, these epistemologists have attempted to respond to the numerous obstacles to reliabilism. Yet all this work has proceeded without regard to the wealth of contemporary work on the metaphysics of dispositions, making the new hope premature at best, ill-founded at worst. Combining contemporary dispositional accounts of justification with extant analyses of dispositions reveals that the latter is the case. The structural differences between epistemic justification and dispositions make it clear that not only should process reliabilism be abandoned, but the subsequent appeal to dispositions along with it.

In the book, I provide an account of what it is for an agent to have an ability. According to the Success View, abilities are all about success across possible situations. In developing and applying the view, the book elucidates the relation between abilities on the one hand and possibility, counterfactuals, and dispositions on the other; it sheds light on the distinction between general and specific abilities; it offers an understanding of degrees of abilities; it explains which role intentions and (...) performances play for the having of an ability, how abilities relate to success and failure, and gives an outlook at how the view might be applied to the free will debate and time travel.

Jack Spencer has recently argued for the striking thesis that, possibly, an agent is able to do the impossible—that is, perform an action that is metaphysically impossible for that person to perform. Spencer bases his argument on (Simple G), a case in which it is impossible for an agent G to perform some action but, according to Spencer, G is still intuitively able to perform that action. I reply that we would have to give up at least four action-theoretical principles (...) if we accept that G is able to do the impossible. We may be best off retaining the principles and thus rejecting Spencer's intuition that G is able to do the impossible. I then consider an argument for the claim that G is able to do the impossible that goes through the Snapshot Principle. I, however, deny that any true variant of the Snapshot Principle shows that G is able to do the impossible. Moreover, the counterexample to the Snapshot Principle that I develop also suggests that G is unable to do the impossible in (Simple G). The most natural explanation for why an agent is unable to perform some action in this counterexample extends to (Simple G). Next, I develop three error theories for why we might initially share Spencer's intuition that G is able to do the impossible in (Simple G). Finally, I consider a couple other "G-cases" of Spencer's and find them all wanting. Perhaps we are unable to do the impossible. (shrink)

It is widely thought that, to be morally responsible for some action or omission, an agent must have had, at the very least, the general ability to do otherwise. As we argue, however, there are counterexamples to the claim that moral responsibility requires the general ability to do otherwise. We present several cases in which agents lack the general ability to do otherwise and yet are intuitively morally responsible for what they do, and we argue that such cases raise problems (...) for various kinds of accounts of moral responsibility. We suggest two alternative approaches to thinking about the connection between moral responsibility and abilities to do otherwise, one of which denies that there is any ability-to-do-otherwise requirement on moral responsibility and the other of which requires only an opportunity to do otherwise. We also argue that a general-ability-to-do-otherwise requirement not only faces counterexamples but also lacks positive motivation. (shrink)

Conventional wisdom suggests that the power to do otherwise is necessary for being morally responsible. While much of the literature on alternative possibilities has focused on Frankfurt’s argument against this claim, I instead focus on one of Dennett’s (1984) arguments against it. This argument appeals to cases of volitional necessity rather than cases featuring counterfactual interveners. van Inwagen (1989) and Kane (1996) appeal to the notion of ‘character setting’ to argue that these cases do not show that the power to (...) do otherwise is unnecessary for moral responsibility. In this paper, I argue that their character setting response is unsuccessful. (shrink)

Is knowledge-how, or “practical” knowledge, a species of knowledge-that, or “theoretical” knowledge? There is no comfortable position to take in the debate around this question. On the one hand, there are counterexamples against the anti-intellectualist thesis that practical knowledge is best analysed as an ability. They show that having an ability to ϕ is not necessary for knowing how to ϕ. On the other hand, the intellectualist analysis of practical knowledge as a subspecies of theoretical knowledge is threatened by its (...) own set of counterexamples, which convincingly establish that practical knowledge lacks many of the typical characteristics of theoretical knowledge. Most strikingly it does not even appear to require a belief. In this paper, I develop an account of practical knowledge that avoids these counterexamples. It also manages to preserve both the status of such knowledge as a cognitive achievement and its apparently close conceptual relation to abilities. I start with the counterexamples against the necessity of abilities for practical knowledge and show that they fail because they underestimate the cognitive demands of attempts. I then make use of the logic of dispositions to bridge the gap that counterexamples against the necessity of abilities for practical knowledge open. It is argued that, instead of the ability to ϕ, it is a specific disposition to have the ability to ϕ that constitutes practical knowledge about ϕ. The resulting theory is an anti-intellectualist position that preserves essential intellectualist motivations and thus should be satisfactory for proponents of both views. (shrink)

In this paper, I argue that it is open to semicompatibilists to maintain that no ability to do otherwise is required for moral responsibility. This is significant for two reasons. First, it undermines Christopher Evan Franklin’s recent claim that everyone thinks that an ability to do otherwise is necessary for free will and moral responsibility. Second, it reveals an important difference between John Martin Fischer’s semicompatibilism and Kadri Vihvelin’s version of classical compatibilism, which shows that the dispute between them is (...) not merely a verbal dispute. Along the way, I give special attention to the notion of general abilities, and, though I defend the distinctiveness of Fischer’s semicompatibilism against the verbal dispute charge, I also use the discussion of the nature of general abilities to argue for the falsity of a certain claim that Fischer and coauthor Mark Ravizza have made about their account.

Though everyday life accords a great deal of significance to practical abilities—such as the ability to walk, to speak French, to play the piano—philosophers of action pay surprisingly little attention to them. By contrast, abilities are discussed in various other philosophical projects. From these discussions, a partial theory of abilities emerges. If the partial theory—which is at best adequate only to a few examples of practical abilities—were correct, then philosophers of action would be right to ignore practical abilities, because they (...) could play no fundamental role in an account of human agency. For the idea that practical abilities *do* play a fundamental role in human agency to be worth considering, an alternative conception of them is needed. As a first step, I attempt some of the necessary ground-clearing work. (shrink)

According to a widely held principle—the poss-ability principle—an agent, S, is able to only if it is metaphysically possible for S to. I argue against the poss-ability principle by developing a novel class of counterexamples. I then argue that the consequences of rejecting the poss-ability principle are interesting and far-reaching.

Logics of joint strategic ability have recently received attention, with arguably the most influential being those in a family that includes Coalition Logic (CL) and Alternating-time Temporal Logic (ATL). Notably, both CL and ATL bypass the epistemic issues that underpin Schelling-type coordination problems, by apparently relying on the meta-level assumption of (perfectly reliable) communication between cooperating rational agents. Yet such epistemic issues arise naturally in settings relevant to ATL and CL: these logics are standardly interpreted on structures where agents move (...) simultaneously, opening the possibility that an agent cannot foresee the concurrent choices of other agents. In this paper we introduce a variant of CL we call Two-Player Strategic Coordination Logic (SCL2). The key novelty of this framework is an operator for capturing coalitional ability when the cooperating agents cannot share strategic information. We identify significant differences in the expressive power and validities of SCL2 and CL2, and present a sound and complete axiomatization for SCL2. We briefly address conceptual challenges when shifting attention to games with more than two players and stronger notions of rationality. (shrink)

Reductive intellectualists (e.g., Stanley & Williamson 2001; Stanley 2011a; 2011b; Brogaard 2008; 2009; 2011) hold that knowledge-how is a kind of knowledge-that. If this thesis is correct, then we should expect the defeasibility conditions for knowledge-how and knowledge-that to be uniform—viz., that the mechanisms of epistemic defeat which undermine propositional knowledge will be equally capable of imperilling knowledge-how. The goal of this paper is twofold: first, against intellectualism, we will show that knowledge-how is in fact resilient to being undermined by (...) the very kinds of traditional (propositional) epistemic defeaters which clearly defeat the items of propositional knowledge which intellectualists identify with knowledge-how. Second, we aim to fill an important lacuna in the contemporary debate, which is to develop an alternative way in which epistemic defeat for knowledge-how could be modelled within an anti-intellectualist framework.

One natural way to argue for the existence of some subjective constraint on agents’ obligations is to maintain that without that particular constraint, agents will sometimes be obligated to do that which they lack the ability to do. In this paper, I maintain that while such a strategy appears promising, it is fraught with pitfalls. Specifically, I argue that because the truth of an ability ascription depends on an (almost always implicit) characterization of the relevant possibility space, different metaethical accounts (...) take obligation to be constrained by different senses of ability. As a result, what initially looks to be a point of consensus—that ability constrains obligation—turns out to be a point of contention, and arguments with this at the foundation are much more likely to obscure, rather than resolve, metaethical disputes. Despite this, appeals to ability in metaethics aren’t doomed to be fruitless. On the contrary, if we can independently establish a particular sense of ability as the normatively relevant one, then we have good grounds for ruling out metaethical accounts that are inconsistent with it. In the final section, I make just such an argument. What seems right about the thought that ability constrains obligation is that an agent cannot be obligated to do that which her circumstances prevent her from doing. I argue that only a sense of ability that is both epistemically and motivationally restricted adequately respects the limits of agential control. (shrink)

This paper offers a novel interpretation of Descartes's conception of freedom that resolves an important tension at the heart of his view. It does so by appealing to the important but overlooked distinction between possessing a power, exercising a power, and being in a position to exercise a power.

Perspectivists hold that what you ought to do is determined by your perspective, that is, your epistemic position. Objectivists hold that what you ought to do is determined by the facts irrespective of your perspective. This paper explores an influential argument for perspectivism which appeals to the thought that the normative is action guiding. The crucial premise of the argument is that you ought to φ only if you are able to φ for the reasons which determine that you ought (...) to φ. We show that this premise can be understood in different ways. On one reading, it provides no support for perspectivism. On another reading, the premise lacks support. So, the argument fails. An important upshot of the paper is that the objectivist can embrace the thought about guidance. (shrink)

Many philosophers accept a response constraint on normative reasons: that p is a reason for you to φ only if you are able to φ for the reason that p. This constraint offers a natural way to cash out the familiar and intuitive thought that reasons must be able to guide us, and has been put to work as a premise in a range of influential arguments in ethics and epistemology. However, the constraint requires interpretation and faces putative counter-examples due (...) to Julia Markovits, Mark Schroeder, and others. This paper develops and motivates an interpretation of the response constraint that avoids the putative counter-examples. (shrink)

This thesis is an investigation into the nature of those abilities that are relevant to free will when the latter is understood as requiring the ability to do otherwise. I assume from the outset the traditional and intuitive picture that being able to do otherwise bestows a significant kind of control on an agent and I ask what kinds of ability are implicated in such control. In chapter 1 I assess the simple conditional analysis of the sense of ‘can’ relevant (...) to free will, and I agree with the consensus that this analysis fails. In chapter 2 I consider Kadri Vihvelin’s contemporary version of the conditional account, which is cast in terms of dispositions. I develop, via engagement with Vihvelin’s view, an account of how modal properties such as dispositions and abilities should be individuated. In chapter 3 I use this account to show why Vihvelin’s account of free will is unsatisfactory. I also show how it helps us to better understand a distinction that is often made in the free will literature, namely, that between some notion of ‘general’ ability on the one hand and a notion of ‘specific’ or ‘particular’ abilities on the other. I argue that there are two important distinctions, both of which are relevant to free will. In chapter 4 I consider Keith Lehrer’s analysis of ‘can’ and conclude that while it fails to achieve Lehrer’s stated aim – namely, that of demonstrating that free will is compatible with determinism – it does contain some useful insights about the kinds of ability relevant to free will. In the fifth and final chapter I switch gears somewhat; I argue that various conditions typically treated under the banner of ‘the epistemic criteria on moral responsibility’ should instead be treated as conditions on an agent’s being able to do otherwise.

Since certain temporal aspects of the relation between duties, rights, and the interests that rights protect have not been fully theorized, a puzzle arises when we come to consider whether and how entities such as members of future generations, fetuses, deceased persons, and unconscious persons are able to possess rights. This paper evolves a unified structure for attributing the ability to possess rights to such entities. It demonstrates that while, under any cogent theory of rights-attributions, rights and duties must be (...) strictly contemporaneous, the interests that rights protect need not temporally coincide with those rights.
