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.

Humean Supervenience is a metaphysical model of the world according to which all truths hold in virtue of nothing but the total spatiotemporal distribution of perfectly natural, intrinsic properties. David Lewis and others have worked out many aspects of HS in great detail. A larger motivational question, however, remains unanswered: As Lewis admits, there is strong evidence from fundamental physics that HS is false. What then is the purpose of defending HS? In this paper, we argue that the philosophical merit (...) of HS is largely independent of whether it correctly represents the world’s fundamental structure. In particular, we show that insofar as HS is an apt model of the world’s higher-level structure, it thereby provides a powerful argument for reductive physicalism and explains otherwise opaque inferential relations. Recent criticism of HS on the grounds that it misrepresents fundamental physical reality is, therefore, beside the point. (shrink)

It is widely believed that at least two developments in the last third of the 20th century have given dispositionalism—the view that powers, capacities, potencies, etc. are irreducible real properties—new credibility: (i) the many counterexamples launched against reductive analyses of dispositional predicates in terms of counterfactual conditionals and (ii) a new anti-Humean faith in necessary connections in nature which, it is said, owes a lot to Kripke’s arguments surrounding metaphysical necessity. I aim to show in this paper that necessity is, (...) in fact, of little help for the dispositionalists. My argument makes use of one of the above mentioned counterexamples against Humean reduction: antidotes. Turning the tables, I ask how the dispositionalists themselves can deal with antidotes. The result will be to show that if the dispositionalists are to demystify antidote cases, they must make plausible a conceptualisation of dispositions that does not invoke any kind of necessity. I will cautiously suggest that the anti-Humean link dispositions bring to the world has to be thought of in terms of (Newtonian) forces. (shrink)

Plausibly, agents act freely iff their actions are responses to reasons. But what sort of relationship between reason and action is required for the action to count as a response? The overwhelmingly dominant answer to this question is modalist. It holds that responses are actions that share a modally robust or secure relationship with the relevant reasons. This thesis offers a new alternative answer. It argues that responses are actions that can be explained by reasons in the right way. This (...) explanationist answer comes apart from the modalist answer. For it holds that actions are responses to reasons if they are explained by those reasons even if they don’t share a modally robust relationship. Explanationism thus offers a novel way of vindicating the intuition that alternative possibilities don’t matter to responding to reasons and (consequently) free agency. The key dialectical position the thesis develops is that both modalism and explanationism constitute attempts to capture he core type of relationship encoded by the notion of a response. Responses to reasons, at core, involve a non-accidental relationship between reason and action. We can either understand non-accidentality as a modal phenomenon – as a modally robust tracking between two facts. Or we can understand non-accidentality as an explanatory phenomenon – as a special explanatory relationship between two facts. According to my rival explanationist proposal, two facts share a non-accidental relationship iff we can give a unified explanation of why both obtain. Unified explanations are explanations of why [p&q] that cannot be decomposed into two (or more) separate independent explanations of p and of q. Consequently, according to explanationism about responding to reasons, actions are responses to reasons iff those reasons offer a rational explanation of the action that cannot be decomposed into separate independent components.

Many think it is plausible that agents enjoy freedom and responsibility with respect to their actions in virtue of being reasons-responsive. Extant accounts spell out reasons-responsiveness (RR) as a general modal property. The agent is responsive to reasons for and against ϕ-ing, according to this idea, if they ϕ in accordance with the balance of reasons in a suitable proportion of possible situations. This paper argues that freedom and responsibility are not grounded in such modal properties on the basis of (...) a phenomenon I call ‘rational blind spots’. Agents have highly specific local blockages (or openings) that prevent them from seeing or reacting for a particular type of reason. When these blind spots are triggered, agents fail to be responsive to reasons in the sense relevant to freedom and responsibility. Thus, we judge that they are not free and responsible. But bind spots don’t remove the agent’s possession of general modal RR properties. Thus, extant accounts of reasons-responsiveness render the incorrect result that the agents in these cases remain responsible because they remain responsive to reasons in a general sense. (shrink)

ABSTRACT There are two tenets about free agency that have proven difficult to combine: free agency is grounded in an agent’s possession or exercise of their reasons-responsiveness, only actual sequence features can ground free agency. This paper argues that and can only be reconciled if we recognise that their clash is just the particular manifestation of a wider conflict between two approaches to the notion of non-accidentality. According to modalism, p is non-accidentally connected to q iff p modally tracks q. (...) According to explanationism, p is non-accidentally connected to q iff q explains p in the right way. The conflict between these two approaches becomes manifest in Frankfurt-like cases for many notions, in which p and q are intuitively non-accidentally connected even though there is no modal tracking between them. Thus, and can’t be combined because the Frankfurt-cases upon which rests track explanationist intuitions, while the non-accidentality requirement of reasons-responsiveness in is usually spelled out in modalist terms. Hence, the possibility of an actual sequence reasons-responsiveness account depends on finding an explanationist approach to the non-accidentality requirement of reasons-responsiveness. (shrink)

This paper takes up Huw Price׳s challenge to develop a retrocausal toy model of the Bell-EPR experiment. I develop three such models which show that a consistent, local, hidden-variables interpretation of the EPR experiment is indeed possible, and which give a feel for the kind of retrocausation involved. The first of the models also makes clear a problematic feature of retrocausation: it seems that we cannot interpret the hidden elements of reality in a retrocausal model as possessing determinate dispositions to (...) affect the outcome of experiments. This is a feature which Price has embraced, but Gordon Belot has argued that this feature renders retrocausal interpretations “unsuitable for formal development”, and the lack of such determinate dispositions threatens to undermine the motivation for hidden-variables interpretations in the first place. But Price and Belot are both too quick in their assessment. I show that determinate dispositions are indeed consistent with retrocausation. What is more, I show that the ontological economy allowed by retrocausation holds out the promise of a classical understanding of spin and polarization. (shrink)

This paper examines recent attempts to revive a classic compatibilist position on free will, according to which having an ability to perform a certain action is having a certain disposition. Since having unmanifested dispositions is compatible with determinism, having unexercised abilities to act, it is held, is likewise compatible. Here it is argued that although there is a kind of capacity to act possession of which is a matter of having a disposition, the new dispositionalism leaves unresolved the main points (...) of dispute concerning free will.

The idea that dispositions are an intrinsic matter has been popular among contemporary philosophers of dispositions. In this paper I will first state this idea as exactly as possible. I will then examine whether it poses any threat to the two current versions of the conditional analysis of dispositions, namely, the simple and reformed conditional analysis of dispositions. The upshot is that the intrinsic nature of dispositions, when properly understood, doesn't spell trouble for either of the two versions of the (...) conditional analysis of dispositions. Along the way, I will propose an extensionally correct and practically useful criterion for identifying nomically intrinsic dispositions and criticize one objection raised by Lewis against the simple conditional analysis of dispositions.

The central theme of this paper is the dispositional/categorical distinction that has been one of the top agendas in contemporary metaphysics. I will first develop from my semantic account of dispositions what I think the correct formulation of the dispositional/categorical distinction in terms of counterfactual conditionals. It will be argued that my formulation does not have the shortcomings that have plagued previously proposed ones. Then I will turn my attention to one of its consequences, the thesis that dispositional properties are (...) not susceptible to intrinsic finks. This thesis was first advanced by me and has ever since stirred up a big controversy, endorsed by some philosophers like Handfield, Bird, and Cohen but rejected by others like Clarke and Fara. Against this background, I will remedy my defense of the impossibility of intrinsically finkable dispositions and then refute some of apparently powerful criticisms of it. And so the upshot is that it is much more reasonable to hold on to the thesis that dispositions are intrinsically unfinkable. This will have the effect of putting the dispositional/categorical distinction on firmer and more secure ground. (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.

I argue that disposition ascriptions—claims like ‘the glass is fragile’—are semantically equivalent to possibility claims: they are true when the given object manifests the disposition in at least one of the relevant possible worlds.

It is a familiar point that many ordinary dispositions are multi-track, that is, not fully and adequately characterisable by a single conditional. In this paper, I argue that both the extent and the implications of this point have been severely underestimated. First, I provide new arguments to show that every disposition whose stimulus condition is a determinable quantity must be infinitely multi-track. Secondly, I argue that this result should incline us to move away from the standard assumption that dispositions are (...) in some way importantly linked to conditionals, as presupposed by the debate about various versions of the ‘conditional analysis’ of dispositions. I introduce an alternative conception of dispositionality, which is motivated by linguistic observations about dispositional adjectives and links dispositions to possibility instead of conditionals. I argue that, because of the multi-track nature of dispositions, the possibility-based conception of dispositions is to be preferred. (shrink)

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.

It is a truth universally acknowledged that a claim of metaphysical modality, in possession of good alethic standing, must be in want of an essentialist foundation. Or at least so say the advocates of the reductive-essence-first view, according to which all modality is to be reductively defined in terms of essence. Here, I contest this bit of current wisdom. In particular, I offer two puzzles—one concerning the essences of non-compossible, complementary entities, and a second involving entities whose essences are modally (...) ‘loaded’—that together strongly call into question the possibility of reducing modality to essence.

According to phenomenal conservatism, seemings can provide prima facie justification for beliefs. In order to fully assess phenomenal conservatism, it is important to understand the nature of seemings. Two views are that (SG) seemings are a sui generis propositional attitude, and that (D2B) seemings are nothing over and above dispositions to believe. Proponents of (SG) reject (D2B) in large part by providing four distinct objections against (D2B). First, seemings have a distinctive phenomenology, but dispositions to believe do not. Second, seemings (...) can provide a non-trivial explanation for dispositions to believe, which wouldn’t be possible if seemings were dispositions to believe. Third, there are some dispositions to believe that are not seemings. Fourth, there are instances of seemings which are not dispositions to believe. I consider and reject each of these objections. The first and third objections rely on a misunderstanding of (D2B). The second objection fails because there are contexts in which an appeal to a previously unknown identity can provide an interesting explanation. The fourth objection overlooks the possibility of finkish and masked dispositions, phenomena which are widely accepted in the dispositions literature. I conclude that (D2B) escapes these common objections unscathed. (shrink)

Dispositions are modal properties. The standard conception of dispositions holds that each disposition is individuated by its stimulus condition(s) and its manifestation(s), and that their modality is best captured by some conditional construction that relates stimulus to manifestation as antecedent to consequent. I propose an alternative conception of dispositions: each disposition is individuated by its manifestation alone, and its modality is closest to that of possibility — a fragile vase, for instance, is one that can break easily. The view is (...) expounded in some detail and defended against the major objections. (shrink)

Dispositions can be masked: some state of affairs might obtain which would prevent an entity from displaying the manifestation characteristic of its disposition. Yet discussions of masks overlook a number of key problems, chief among them the probabilistic nature of many dispositional masks. In this paper, I highlight the manner in which past analyses of dispositional masks have been unable to solve the problem of masks. I propose an analysis of dispositional masks which focuses on this and a number of (...) other problems, which I argue can address them better than past accounts can. I argue that some entity masks some disposition just in case that entity makes it such that the disposition is less likely to manifest, or such that it will manifest to a lower degree. (shrink)

Given that an analysis of disposition ascription cannot be made in terms of a simple subjunctive conditional, we present a multiply qualified conditional analysis that places disposition ascription within an implicit fundamental causal conceptual typography within which a disposition ascription is embedded, framed, and understood. By placing the multiply qualified analysis within an implicit causal matrix involving a focal cause, pathway of influence, mechanism of action, contributing/partial cause, mediator, extrinsic moderator,, intrinsic moderator, and manifestation, we show how this analysis evades (...) counterexamples and arguments raised against the simple conditional analysis. We then indicate how the causal conceptual landscape provides a roadmap for unpacking and explicating parameters of the ceteris paribus qualifier to acquit the analysis of charges of being vacuous or irredeemably vague.

Powers are properties defined by what they do. The focus of the large majority of the powers literature has been mainly put on explicating the (multifaceted) results of the production of a power in certain (multifaceted) initial conditions: but all this causal complexity is bound to be—and, in fact, it has proved to be—quite difficult to handle. In this paper we take a different approach by focusing on the very activity of producing those multifaceted manifestations themselves. In this paper, we (...) propose an original account of what the essence of a power consists in which stems from a radical reconceptualisation of power-causation according to which counterfactuals are to be explained away by powers, and not vice-versa. We call this approach the dynamical operator account of powers. According to this account, the causal role of powers consists in their ensuring that the ontological transition from a stimulus S to a manifestation M happens. Powers thus have a dynamical essence which consists in the fundamental activity of generating the counterfactuals typically associated with them. We show that if one conceptualises this functional activity as the metaphysical fulcrum around which counterfactual-based causation revolves, one is granted not only an improved methodology to individuate powers but also a better understanding of their knowability, modality and directedness.

Hylomorphism is the Aristotelian theory according to which objects are composites of form and matter. Form is what unifies the various parts of an object – the matter – into a cohesive whole. Some contemporary hylomorphists argue their theory applies beyond the realm of concreta, and that it explains the unity of various abstract entities. Not everyone agrees. Recent criticism alleges that hylomorphism fails to explain the unity of certain abstract entities, namely, complex properties – properties with other properties as (...) proper parts. Here, I both respond to this criticism and show that and how hylomorphism extends to the domain of complex properties. By discussing hylomorphism’s applicability to the hitherto unchartered domain of complex properties, I hope to defend its credentials as a general mereological theory. (shrink)

As Price (2009) famously mused, if a philosopher were to be magically transported, perhaps through means of time travel, from the 1950s to the modern day, they would indeed be shocked by the resurgence of metaphysics in the analytic tradition. Most of all, perhaps, they would be shocked by the popularity of power metaphysics. What a strange item to have in a philosopher’s curriculum, they might think: after all, didn’t David Hume claim that “[t]here are no ideas which can occur (...) in metaphysics more obscure and uncertain than those of power, force, energy, or necessary connection”? Indeed, much has changed since then. At the pain of using overly vague terminology, we can call “power metaphysics” the subdiscipline of metaphysics interested in the development and evaluation of a family of positions which we will refer to under the umbrella term of “dispositionalism”. According to dispositionalists, the world we inhabit is also populated by genuine and irreducible powers, dispositions, and capacities of objects. (shrink)

I defend a theory of the way in which death is a harm to the person who dies that fits into a larger, unified account of harm ; and includes an account of the time of death's harmfulness, one that avoids the implications that death is a timeless harm and that people have levels of welfare at times at which they do not exist.

Choi (Philosophia, 38(3), 2010) argues that my counterexamples in Lee (Philosophia, 38(3), 2010) to the simple conditional analysis of disposition ascription are bogus counterexamples. In this paper, I argue that Choi’s arguments are not satisfactory and that my examples are genuine counterexamples.

D. Lewis proposed the reformed conditional analysis of disposition to handle Martin's influential counterexamples to the simple counterfactual analysis. Some philosophers, however, argue that the mere fact that the reformed conditional analysis of disposition can handle Martin's counterexamples should not be regarded as a reason to prefer the reformed conditional analysis to the simple analysis. In this paper, I argue that the reformed version should be preferred not because it can handle Martin's counterexamples but because there are other counterexamples to (...) the simple conditional analysis.

In this paper we argue that the moral value of an agent is determined solely by their dispositions to act intentionally and freely. We then put this conclusion to work. It resolves a putative moral paradox first posed by Saul Smilansky, and it undermines a prominent line of argument for a variety of Trinitarian theology. Finally, we derive our conclusion about the moral worth of agents not only from our initial series of thought experiments, but also from Abrahamic theism itself. (...) This means that Smilansky’s paradox can only possibly be rehabilitated by an atheist, and that the aforementioned line of argumentation for the Trinity is radically self-undermining, since it relies upon the denial of a corollary of Abrahamic theism.

Are there dispositions which not only do not manifest, but which could not manifest? We argue that there are dispositions to Ф in circumstances C where C is impossible, and some where Ф is impossible. Furthermore, postulating these dispositions does useful theoretical work. This paper describes a number of cases of dispositions had by objects even though those dispositions are not possibly manifest, and argues for the importance of these dispositions.

In this paper, we explicate an underappreciated distinction between two conceptions of valuing. According to the first conception, which we call the surface-account, valuing something is exclusively a matter of having certain behavioral, cognitive, and emotional dispositions. In contrast, the second conception, which we call the layer-account, posits that valuing is constituted by the presence of certain representational mental states underlying those dispositions. In the first part of the paper, we introduce the distinction in proper detail and show that the (...) accounts have different implications regarding the valuings of agents. In the second part, we situate the accounts within the extant philosophical literature. First, we relate them to the recent debate between so-called dispositionalists and representationalists about the nature of beliefs and point out that this debate can help anticipate some of the main dialectical fault lines to be expected between surface- and layer-theorists. Second, we examine the contemporary meta-ethical debate on conceptualizing valuing, indicate that scholars have largely ignored the distinction introduced here, and outline that this oversight has substantial theoretical costs: as we show, key arguments within the meta-ethical debate require thorough re-evaluation in light of the proposed distinction. The third part of the paper illustrates the theoretical leverage of the distinction for practical research by exploring its implications for behavioral welfare economics. (shrink)

– We offer a new motivation for imprecise probabilities. We argue that there are propositions to which precise probability cannot be assigned, but to which imprecise probability can be assigned. In such cases the alternative to imprecise probability is not precise probability, but no probability at all. And an imprecise probability is substantially better than no probability at all. Our argument is based on the mathematical phenomenon of non-measurable sets. Non-measurable propositions cannot receive precise probabilities, but there is a natural (...) way for them to receive imprecise probabilities. The mathematics of non-measurable sets is arcane, but its epistemological import is far-reaching; even apparently mundane propositions are liable to be affected by non-measurability. The phenomenon of non-measurability dramatically reshapes the dialectic between critics and proponents of imprecise credence. Non-measurability offers natural rejoinders to prominent critics of imprecise credence. Non-measurability even reverses some of the critics’ arguments—by the very lights that have been used to argue against imprecise credences, imprecise credences are better than precise credences.

Do causes necessitate their effects? Causal necessitarianism is the view that they do. One major objection—the “monotonicity objection”—runs roughly as follows. For many particular causal relations, we can easily find a possible “blocker”—an additional causal factor that, had it also been there, would have prevented the cause from producing its effect. However—the objection goes on—, if the cause really necessitated its effect in the first place, it would have produced it anyway—despite the blocker. Thus, CN must be false. Though different (...) from Hume’s famous attacks against CN, the monotonicity objection is no less important. In one form or another, it has actually been invoked by various opponents to CN, past and present. And indeed, its intuitive appeal is quite powerful. Yet, this paper argues that, once carefully analysed, the objection can be resisted—and should be. First, I show how its success depends on three implicit assumptions concerning, respectively, the notion of cause, the composition of causal factors, and the relation of necessitation. Second, I present general motivations for rejecting at least one of those assumptions: appropriate variants of them threaten views that even opponents to CN would want to preserve—in particular, the popular thesis of grounding necessitarianism. Finally, I argue that the assumption we should reject is the one concerning how causes should be understood: causes, I suggest, include an element of completeness that excludes blockers. In particular, I propose a way of understanding causal completeness that avoids common difficulties. (shrink)

The problem of masking is widely regarded as a grave threat to the conditional analysis of dispositions. Unlike the difficulty arising in connection with finkish situations, the problem does not involve the (dis)appearance of a disposition upon the arrival of its activating conditions. Consequently, some promising responses to the finkish cases, in particular David Lewis's reformed analysis, are ill-equipped to deal with masks. I contend that the difficulty posed by masks can be surmounted by supplementing the counterfactual at the heart (...) of the conditional analysis with a ceteris paribus clause. In spelling out this idea, I first examine the issue of provisos in nomic statements. Then I show how the employment of the ceteris paribus clause escapes the objections that are often raised against it, including the charge that the clause cannot informatively capture all the possible masks of a disposition.

In this paper we develop an analysis of dispositions by means of causal Bayes nets. In particular, we analyze dispositions as cause-effect structures that increase the probability of the manifestation when the stimulus is brought about by intervention in certain circumstances. We then highlight several advantages of our analysis and how it can handle problems arising for classical analyses of dispositions such as masks, mimickers, and finks.

I argue for the existence of intrinsic Finks, Masks, and Mimics, and argue that these undermine certain recent attempts to revive simple conditional analyses of dispositions. I present some examples of intrinsic Finks, Masks, and Mimics, and argue that the example of an intrinsic fink I present has certain advantages over the examples of intrinsic finks recently suggested by Randolph Clarke. I conclude that the existence of such Finks, Masks, and Mimics, undermine a recent attempt by Sungho Choi to distinguish (...) dispositional properties from categorical properties. (shrink)

Philosophers almost universally believe that concepts of supervenience fail to satisfy the standards for physicalism because they offer mere property correlations that are left unexplained. They are thus compatible with non-physicalist accounts of those relations. Moreover, many philosophers not only prefer some kind of functional-role theory as a physically acceptable account of mind-body and other inter-level relations, but they use it as a form of “superdupervenience” to explain supervenience in a physically acceptable way. But I reject a central part of (...) this common narrative. I argue that functional-role theories fail by the same standards for physicalism because they merely state without explaining how a physical property plays or occupies a functional role. They are thus compatible with non-physicalist accounts of that role-occupying relation. I also argue that one cannot redeploy functional-role theory at a deeper level to explain role occupation, specifically by iterating the role-occupant scheme. Instead, one must use part-whole structural and mechanistic explanations that differ from functional-role theory in important ways. These explanations represent a form of “superduperfunctionalism” that stand to functional-role theory as concepts of superdupervenience stand to concepts of supervenience. (shrink)

Since the mid-90s dispositionalism, the view that dispositions are irreducible, real properties, gained strength due to forceful counterexamples (finks and antidotes) that could be launched against Humean anti-dispositionalist attempts to reductively analyse dispositional predicates. -/- In the light of these anti-Humean successes, and in combination with ideas surrounding metaphysical necessity put forward by Kripke and Putnam, some dispositionalists felt encouraged to propose a strong anti-Humean view under the name of “Dispositional Essentialism”. -/- In this paper, I show that, ironically, the (...) counterexamples dispositionalists have used against the Humean reductive analysis of dispositional predicates also prove to be problems for a strong form of dispositional essentialism that assimilates dispositionality and metaphysical necessity. -/- Help comes from an unlike ally—Carnapian reductions sentences—but the alliance is not unproblematic.

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)

In this thesis I investigate the question of whether or not dispositional properties are able to necessitate their manifestations. I provide three main discussions that reflect three aspects of my question. The first and second discussions concern different aspects of the 'problem of prevention'. This is the premise that causal interactions can be subject to interference/prevention, generally construed. A number of philosophers have argued that the problem of prevention undercuts the necessitation of lawful regularities in the context of dispositional essentialism. (...) We can term this issue the 'necessitation issue'. In the first discussion I examine whether or not antidotes qua preventative entities are metaphysically possible within the context of Alexander Bird's dispositional monism. I argue that Bird's theory raises a problem of ontological representation re antidotes. The line of thought in this discussion is that it is difficult for Bird to say what antidotes are and how they operate; nevertheless, in this discussion I provide a solution to my problem that stays within the confines of Bird's dispositional monism. In this section of the thesis I remain neutral on the necessitation issue, but I take myself to clarify the question of whether or not dispositional properties are able to necessitate their manifestations by criticising Bird's model of antidotes/prevention and setting out a replacement. In the second discussion I examine Stephen Mumford and Rani Lill Anjum's anti-necessitarian strategies. Mumford and Anjum's 'causal dispositionalism' encompasses a theory of dispositional properties, antidotes, and prevention. Mumford and Anjum's causal dispositionalism is not subject to the problem of ontological representation that Bird's theory raises; nevertheless, I argue that their theory is multiply problematic. The purpose of this discussion, taken as a whole, is to show that a recent strategy for attacking the necessitarian claim of dispositional essentialism is weaker than it has appeared to a number of philosophers. In this section of the thesis I move from a neutral stance on necessitation to a defensive stance. In the first two stages of the thesis, which concern the problem of prevention, I work with the background assumption that dispositional essentialism is a tenable position. In the third section of this thesis, however, I begin by endorsing Stephen Barker's essay The Emperor's New Metaphysics of Powers, which argues that the main articulations of dispositional essentialism are either internally inconsistent or otherwise disguised versions of brute modalism, where brute modalism focuses upon possible worlds as oppose to properties. In response, I develop a replacement position for dispositional essentialism that I term 'temporal essentialism'. I advance temporal essentialism as a prototype position in the properties and laws debate. It aims to provide a metaphysical explanation for lawful regularities by drawing upon the passage of time. In short, temporal essentialism is the position that it is built into a system of ontology that it dynamically adds new entities to its ontological categories and constructs states of affairs in a rule-following way.

According to one large family of views, scientific explanations explain a phenomenon (such as an event or a regularity) by subsuming it under a general representation, model, prototype, or schema (see Bechtel, W., & Abrahamsen, A.

A neurocomputational perspective: The nature of mind and the structure of science. Cambridge: MIT Press; Darden (2006); Hempel, C. G. (1965). Aspects of scientific (...) explanation. In C. G. Hempel (Ed.), Aspects of scientific explanation (pp. 331–496). New York: Free Press; Kitcher (1989); Machamer, P., Darden, L., & Craver, C. F. (2000). Thinking about mechanisms. Philosophy of Science, 67(1), 1–25). My concern is with the minimal suggestion that an adequate philosophical theory of scientific explanation can limit its attention to the format or structure with which theories are represented. The representational subsumption view is a plausible hypothesis about the psychology of understanding. It is also a plausible claim about how scientists present their knowledge to the world. However, one cannot address the central questions for a philosophical theory of scientific explanation without turning one’s attention from the structure of representations to the basic commitments about the worldly structures that plausibly count as explanatory. A philosophical theory of scientific explanation should achieve two goals. The first is explanatory demarcation. It should show how explanation relates with other scientific achievements, such as control, description, measurement, prediction, and taxonomy. The second is explanatory normativity. It should say when putative explanations succeed and fail. One cannot achieve these goals without undertaking commitments about the kinds of ontic structures that plausibly count as explanatory. Representations convey explanatory information about a phenomenon when and only when they describe the ontic explanations for those phenomena. (shrink)

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)

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”).

Dispositions and potentialities seem importantly similar. To talk about what something has the potential or disposition to do is to make a claim about a future possibilitythe "threats and promises" that fill the world (Goodman 1983, 41). In recent years, dispositions have been the subject of much conceptual analysis and metaphysical speculation. The inspiration for this essay is the hope that that work can shed some light on discussions of potentiality. I compare the concepts of disposition and potentiality, consider whether (...) accounts of these concepts are subject to similar difficulties, and whether having a disposition or a potentiality can depend on extrinsic factors. The concept of a disposition I am working with is drawn from the recent literature in metaphysics and philosophy of science that focuses on the analysis of dispositional concepts and their role in a broader ontology. The concept of a potentiality is drawn from the bioethics literature that focuses on the moral relevance of potentialities that subjects of medical decisions mayor may not possess. Some preliminary conclusions I draw are the following: I. Potentialities are dispositions; 2. Due to problematic cases, potentiality ascriptions, like disposition ascriptions, are not reducible to counterfactual statements; and 3. Like dispositions, some potentialities can be extrinsic. Here I do not aim to draw any conclusions about the moral relevance of potentialities but rather to outline conceptual and metaphysical options available to those who seek to employ this concept. However, to the extent that these options are relevant to answering moral questions, I am skeptical about the prospects of finding a value-neutral way to choose between them. I have tried to outline a number of options regarding the nature of potentialities for those who would like that notion to play some role in their theorizing in bioethics, or elsewhere. There still are a number of decisions to make about how to explicate the concept of potentiality that is most relevant for one's purposes. How should one flesh out the associated counterfactuals, regardless of whether they hope to reduce potentiality claims to counterfactual conditionals? How should one circumscribe the relevant possible circumstances of manifestation for a given potentiality? Are the circumstances necessary for the actualization of a given potentiality to be counted circumstances of possession or circumstances of manifestation? Is the kind of which something is potentially a member a natural kind or a class whose membership is determined by convention? My anticipation, and perhaps my worry, is that these questions do not have answers that can be determined independently from the conclusions about the moral relevance of potentiality that a given theorist aims to establish.
