In this thesis, I develop a nonreductive and general conception of potentiality, and explore the prospects of a realist account of possibility based on this account of potentiality. Potentialities are properties of individual objects; they include dispositions such as fragility and abilities such as the ability to play the piano. Potentialities are individuated by their manifestation alone. In order to provide a unified account of potentialities, I argue in chapter 2 that dispositions, contrary to philosophical orthodoxy, are best understood in (...) terms only of their manifestations (as disposi- tions to ...), rather than in terms of a stimulus and a manifestation condition (as dispositions to ... if ...). Chapter 3 provides some preliminary motivation for a nonreductive and gen- eral account of potentiality, and chapter 4 develops such an account. The guiding question is how far the notion of potentiality can be extended from the initial ex- amples of familiar dispositions and abilities, and it is argued that it can be extended very far. Various features of potentialities are explored, among them extrinsicality, iterations of potentiality, and the behaviour of potentiality with regard to logical equivalence. In chapter 5, the account is set to work in providing the outlines and a defense of a potentiality-based account of possibility. The basic idea of such an account is that it is possible that p just in case some thing has a potentiality for p. The account is defended against the objection that there may not be enough potential- ities to ground all the possibilities that there are. Finally, in chapter 6, a logic of potentiality is formulated and the logic of possibility derived from it, showing that the potentiality-based account of possibility is formally adequate: it provides pos- sibility with the formal features that modal logicians have studied. I conclude that the proposed account of possibility is a promising research programme. (shrink)

Reductionists about dispositions must either say the natural properties are all dispositional or individuate properties hyperintensionally. Lewis stands in as an example of the sort of combination I think is incoherent: properties individuated by modal profile + categoricalism.

Our doxastic states are our belief-like states, and these include outright doxastic states and degreed doxastic states. The former include believing that p, having the opinion that p, thinking that p, being sure that p, being certain that p, and doubting that p. The latter include degrees of confidence, credences, and perhaps some phenomenal states. But we also have conviction (being convinced simpliciter that p) and degrees of conviction (being more or less convinced that p). This volume shows: how and (...) why all of the outright doxastic states mentioned above can be reduced to conviction thresholds; what degrees of conviction fundamentally are (degreed reliance-dispositions); why degrees of conviction are not credences; when suspending a belief is compatible with continuing to believe; and the surprising extent to which Kant endorsed the theory of conviction that emerges in this volume.

Beliefs can be resistant to evidence. Nonetheless, the orthodox view in epistemology analyzes beliefs as evidence-responsive attitudes. I address this tension by deploying analytical tools on capacities and masking to show that the cognitive science of evidence-resistance supports rather than undermines the orthodox view. In doing so, I argue for the claim that belief requires the capacity for evidence-responsiveness. More precisely, if a subject believes that p, then they have the capacity to rationally respond to evidence bearing on p. Because (...) capacities for evidence-responsiveness are fallible and may be masked, beliefs can be held in the face of counter-evidence. Indeed, I will argue that our best science of belief supports the claim that evidence-resistant beliefs result from masks on evidence-responsiveness capacities. This account of belief not only allows for resistance to evidence, but provides us with a framework for describing and explaining actual cases of evidence-resistance. (shrink)

Modal dispositionalism is the view that possibilities are a matter of the dispositions of individual objects: it is possible that p if and only if something has a disposition for p to be the case. We raise a problem for modal dispositionalism: nothing within the theory rules out that there could be necessary, perfect masks, which make the manifestation of a disposition impossible. Unless such necessary perfect masks are ruled out, modal dispositionalism runs the risk of failing to provide a (...) sufficient condition for possibility, and indeed of engendering contradictions. But to rule them out, modal dispositionalism would have to revise a crucial tenet of the view, its localism. (shrink)

What is sexual orientation? The contemporary consensus among philosophers is that it is a disposition. Unsurprisingly, recent debates about the metaphysics of sexual orientation are almost entirely intramural. Behavioral dispositionalists argue that sexual orientation is a disposition to behave sexually. Desire dispositionalists argue that it is a disposition to desire sexually. We argue that sexual orientation is not best understood in terms of dispositions to behave or dispositions to desire before arguing that dispositions tout court fail to illuminate sexual orientation. (...) We then introduce and defend the idea that sexual orientation is best understood in terms of categorical phenomenal properties of sexual arousal. (shrink)

I defend the relatively orthodox view that reasons for action are premises in good practical reasoning, against recent counterexamples that suggest that, like “government house” moral justifications, some reasons are to be ignored in deliberation. I also explain, positively, what is right about the orthodoxy. Unless reasons are premises in good practical reasoning, reasons cannot be normative in the way they are usually taken to be, and relatedly, are unfit to play certain familiar theoretical and related everyday roles that give (...) many appeals to reasons their distinctive point.

This morning I intended to get out of bed when my alarm went off. Hearing my alarm, I formed the intention to get up now. Yet, for a time, I remained in bed, irrationally lazy. It seems I irrationally failed to execute my intention. Such cases of execution failure pose a challenge for Mentalists about rationality, who believe that facts about rationality supervene on facts about the mind. For, this morning, my mind was in order; it was my action that (...) apparently made me irrational. What, then, should Mentalists say about the phenomenon of execution failure? The phenomenon of execution failure, and the puzzle it raises for Mentalists, have rarely been discussed. This paper addresses the puzzle in two parts. First, it argues that execution failure is a real phenomenon. It is possible for agents to irrationally fail to act on their present-directed intentions. It follows that Mentalists in the philosophy of action must solve the puzzle of explaining what is irrational about cases of execution failure. Second, this paper begins the search for such a solution. It considers six possible resolutions to the puzzle, arguing that none is obviously the most attractive. These resolutions include a requirement of overall conative consistency, an appeal to the norm of intention consistency, a form of Volitionalism, an appeal to factive mental states, and a proposal due to Garrett Cullity, and a novel requirement of proper functioning.

What does it mean to know how to do something? This book develops a comprehensive account of know-how, a crucial epistemic goal for all who care about getting things right, not only with respect to the facts, but also with respect to practice. It proposes a novel interpretation of the seminal work of Gilbert Ryle, according to which know-how is a competence, a complex ability to do well in an activity in virtue of guidance by an understanding of what it (...) takes to do so. This idea is developed into a full-fledged account, Rylean responsibilism, which understands know-how in terms of the normative guidance and responsible control of one's acts. Within the complex current debate about know-how, this view occupies a middle ground position between the intellectualist claim that know-how just is propositional or objectual knowledge and the anti-intellectualist claim that know-how just is ability. In genuine know-how, practical ability and guiding intellect are both necessary, but essentially intertwined. (shrink)

It is held by some philosophers that it is possible that x has a disposition D but, if the stimulus condition obtains, it won’t manifest D because of an intrinsic interference. I will criticize this position on the ground that it has a deeply sceptical consequence, for instance, that, assuming that I am not well informed of the micro-properties of a metal coin, I do not know that it is not water-soluble. But I urge that this is beyond the pale, (...) especially in light of the weight of the practical considerations we take when we use dispositional concepts in everyday life or science. In doing so, further, I will formulate a type of belief-forming inference and claim that it confers justification on commonsensical dispositional beliefs like the one that a metal coin isn’t water-soluble.

Is it possible that one and the same object x has opposing dispositions at the same time? One's first reaction might be that it is evidently impossible. On the assumption that x is incombustible, it seems to follow that it is not combustible. Surprisingly enough, however, it is claimed that there are a number of examples in support of the possibility of simultaneous co-instantiation of opposing dispositions. In this paper, I will bring under scrutiny some of the examples and come (...) to the conclusion that none of them achieve the desired goal. This will give support to the initial intuition that opposing dispositions cannot be co-instantiated by one and the same object at the same time. (shrink)

Future-directed intentions, it is widely held, involve behavioral dispositions. But of what kind? Suppose you now intend to Φ at future time t. Are you thereby now disposed to Φ at t no matter what? If so, your intention disposes you to Φ even if around t you will come to believe that Φ-ing would be crazy. And would not that be a crazy intention to have? – Like considerations have led Luca Ferrero and others to believe that only intentions (...) with strong internal conditions are capable of rationality. This paper explores in how far a broadly dispositional view of intention supports their claims. Its first point will come as a surprise: Intentions indeed involve dispositions toward follies in plenty. Natural objections against this bizarre-sounding claim are shown to fail, and standard counterfactual analyses of disposition locutions are shown to underpin it further. However, since the dispositions at issue are pro tanto dispositions, the consequences are not as odd as might be expected: When hedged by reasonable habits to reconsider one’s intentions, dispositions toward follies do not entail any actual crazy behavior. On balance, unconditional intention is therefore found rational after all. Dispositions toward crazy actions need not be crazy dispositions. (shrink)

Recently, Choi has argued that current accounts of intrinsically finkable dispositions lead to absurd consequences in certain everyday cases. In this paper I offer a new argument for the existence of intrinsically finkable dispositions, one which provides a new way of testing for the presence of such dispositions. It is then argued that, with this new test in place, Choi’s examples no longer present a problem for the view that some dispositions are intrinsically finkable.

This thesis proposes that key, competing theories of dispositions mistake and conflate how we identify, designate and talk about dispositions and dispositional terms for the nature of dispositions and the meaning of dispositional terms when they argue that: a) dispositions are extrinsic properties of their bearers (Boyle 1666) b) all properties are purely dispositional (Bird 2007) c) all properties are purely categorical (there are no dispositional properties) (Armstrong in AMP 1996) d) dispositional and categorical properties are separate and distinct properties (...) (Prior, Pargetter and Jackson 1982). In so doing these theories make unwarranted and unsupported ontological conclusions about dispositions. The thesis traces the principal source of this confusion and conflation to a reliance on the counterfactual analysis of dispositions that wrongly encourages the conflation of a disposition (say fragility) with its manifestation (shattering). There is good reason to hold that the counterfactual analysis of dispositions is false — the truth of a counterfactual statement (such as “if x were dropped x would break”) is neither necessary nor sufficient for the truth of a dispositional ascription (such as “x is fragile”). (shrink)

There seems to be some kind of close relationship between desires and behavioral dispositions. While a popular view about the nature of desire is that it essentially involves dispositions towards action, there do seem to be pressing objections to this view. However, recent work on dispositional properties potentially undermines some of the metaphysical assumptions that lie beneath these objections.

Masks, interferers, finks, reverse finks, and mimickers are troublesome for powers metaphysics insofar as the latter concedes that there are powers with essential stimuli/activation conditions. In this article, I aim at offering a novel approach for solving this problem. In Section 1, I shall present the problem; and in Section 2, I shall briefly show how it also arises within non‐reductive views of powers. Subsequently, in Section 3, I shall examine the failure of the ceteris paribus solution. The pars construens (...) will begin in Section 4, where I shall distinguish between the activation conditions, the background conditions, and the possession conditions of a power. Within each category, I shall draw further distinctions. In Section 5, I shall demonstrate how such distinctions may ground a solution to our problem. Finally, in Section 6, I shall anticipate and reply to four objections. (shrink)

Many recently released Hollywood films feature superheroes like Superman, Ironman, the Hulk, Optimus Prime, and so on who possess amazing superpower and defeat supervillains with unassailable commitment to moral justice. Interestingly, different superheroes possess and exercise their superpower in very different fashions. What is more, this aspect of their difference is intimately related to an issue that is lately in intense debate among metaphysicians of powers and dispositions, the issue of the possibility of intrinsic interferers with dispositions. This paper will (...) argue that a strong case can be made against this possibility when we give due weight to the commonsensical understanding of superheroes and their superpower. Whilst other arguments have been raised against the possibility of intrinsic interferers with dispositions in the latest literature, this will present further difficulties for those who accept it.

There's a student in my philosophy class who has "real potential." I might express this thought in any of the following ways: "She is potentially a philosopher"; "She is a potential philosopher"; "She has the potential to be a philosopher." The first way uses a cognate of "potential" as an adverb to modify "is." The second ways uses "potential" as an adjective to modify "philosopher." However, the third way uses "potential" as a noun to refer to something that the student (...) has. What kind of thing is this potential? One worry about even asking this question is that this nominalization of the adjective "potential" suggests a metaphysical picture that is an artifact of language. This is even more strongly suggested by the less ambiguous nominalization "potentiality." Once we have the term "potentiality," we have a new kind of entity to countenance, and questions about its nature arise. One might argue, just because we use the word "potentiality," we should not think that it refers to a "thing" that someone can "have." There is something disingenuous about such an argument. It proceeds as if the adverbial and adjectival uses of "potential" are unproblematic, and questions only arise with the nominalization. But it is not obvious what it means to potentially be something, or what it means to be a potential something. To say that someone "is potentially" a philosopher is to talk about a way of being that falls short of actuality. And a "potential philosopher" is not a kind of philosopher at all. So what is it? Each of the three above formulations is a modal claim. If there is anything philosophical puzzling about a potentiality claim, it is not going to go away by translating it into an equivalent modal claim. In this chapter I defend the existence of potentialities against anti-realist arguments, and make a proposal as to their nature. The proposal, in short, is that potentialities are properties, specifically dispositions, though more needs to be said about properties and dispositions. I will do this in Part I. In Part II, I will address two lines of argument against potentialities: that they are reducible, and that they are causally inert. (shrink)

In ‘Finkish Dispositions’, David Lewis proposed a revised conditional analysis of dispositions, designed to rule out counterexamples based on finkish dispositions and finkish lacks of dispositions. Bird and Choi have argued that Lewis’s amended analysis is vulnerable to two further types of counterexamples trading on mimicked and masked dispositions. This paper provides a diagnosis of why Lewis’s analysis inherits these problems, and investigates whether the means can be found—in Lewis’s paper or elsewhere—to defend his analysis against the counterexamples. A range (...) of strategies for defending conditional analyses against masking and mimicking counterexamples are assessed. The conclusion is that none of them will save Lewis’s analysis; some strategies fail, while the rest threaten to make Lewis’s amendments redundant. The discussion offers a number of general lessons about how to defend conditional analyses of dispositions. (shrink)

Agents sometimes act for normative reasons—for reasons that objectively favor their actions. Jill, for instance, calls a doctor for the normative reason that Kate is injured. In this article I explore a dispositional approach to acting for a normative reason. I argue for the need of epistemic, motivational, and executional dispositional elements of a theory of acting for a normative reason. Dispositions play a mediating role between, on the one hand, the normative reason and its normative force, and the action (...) on the other hand. Thereby, they help to deal with problem cases such as cases of deviant causal chains and improper instrumental motivation. (shrink)

The glass vase on my desk is fragile. It should be handled with care because it it is likely to shatter or crack if it is knocked, dropped, or otherwise treated roughly. The vase has certain dispositions, for example the disposition to shatter when dropped. But what is this disposition? It seems on the one hand to be a perfectly real property, a genuine respect of similarity common to glass vases, china cups, ancient manuscripts, and anything else fragile. Yet on (...) the other hand my vase's disposition seems mysterious, "ethereal" (as Nelson Goodman (1954) put it) in a way that, say, its size and shape properties are not. For my vase's disposition, it seems, has to do only with its possibly shattering in certain conditions, conditions which I hope will never be realized. In general, it seems that nothing about the actual behavior of an object is ever necessary for it to have the dispositions it has. Many objects differ from each other with respect to their dispositions in virtue of their merely possible behavior, and this is a mysterious way for objects to differ. (shrink)

Contemporary emotion research typically takes the phenomenon of emotion to be exhausted by a class of mental events that are intentional, conscious, and related to certain sorts of behaviour. Moreover, other affective phenomena, such as moods, are also considered to be relatively short-term, episodic, or occurrent states of the subject undergoing them. Emotions, and other putative emotional phenomena that common-sense takes as long-lasting, non-episodic, or dispositional are things that both philosophers and scientists sometimes recognise, but that are relatively neglected in (...) comparison to emotional episodes. This thesis aims at showing that this neglect is unjustified. I will argue that there is a class of entities, 'sentiments'—broadly characterised as dispositions to undergo emotional episodes—that are irreducible to emotional episodes or collections thereof and have properties that make them a suitable target of study by the emotion researcher.In the first chapter, I argue that an analysis of caring as a pattern of emotional episodes, while more plausible than alternative, non-emotional accounts, faces a number of counterexamples that motivate the search for an account of caring as related in a certain way to emotions but as irreducible to them. I argue that a dispositional account, according to which dispositions are conceived as distinct from their manifestations, is an account for which a strong case can be made.The second chapter is dedicated to defending a modest form of realism about dispositions in general and psychological dispositions in particular. According to realism, dispositions are genuine properties that, although perhaps reducible to non-dispositional properties, cannot be re-described in terms of events only. In the third chapter, I show in what ways emotional dispositions can positively contribute to the explanation of the occurrence of emotional episodes. In the fourth chapter, I argue that caring, understood as a species of sentiment, is not to be construed as a mere disposition to produce certain events; rather, we should allow that certain dispositions are genuinely mental or psychological. Assuming realism about the mental, I argue that some dispositions are mental in a way that others are not. I suggest that being intentional is the property that makes psychological dispositions genuinely mental. I end the chapter by drawing a connection between caring and the notion of character. On my view, caring is at least a necessary ingredient of certain character traits, in particular the virtues. In chapter five, I tackle a recent form of empirically informed scepticism about character and argue, on the basis of general considerations about psychological dispositions, that the sceptic’s case is not as strong as she makes out. Finally, in chapter six, I argue that at least certain forms of sentiment, for example romantic love, can be genuinely supported by reasons, thereby suggesting a way they can contribute to the value of our lives. Overall, the aim of this thesis is to establish the respectability of sentiments in a sophisticated account of the mind. (shrink)

Dispositional accounts of various phenomena have claimed that dispositions can be intrinsically masked. In cases of intrinsic masking, something has a disposition while also having an intrinsic property that would prevent that disposition from manifesting in the face of its stimulus. This paper develops a theory of disposition ascriptions capable of recognizing such dispositions. The theory is modeled on the view that dispositions are powers. I propose that having a disposition is a matter of exerting a corresponding kind of influence. (...) Unlike powers theories, however, the account largely falls silent on questions of fundamental metaphysics. It does not build dispositions into fundamental ontology, posit necessary connections between properties, or otherwise appeal to sui generis modality. (shrink)
