Leading expressivist proposals characterize the mental state expressed in the making of a normative judgment solely in terms of intrinsic, psychological dispositions. As a result, they fail to capture a subset of the normative judgments that agents can and do make; they miss the way that external factors can influence what the making of a normative judgment looks like. This problem can be seen most plainly in the context of systemic oppression. Intuitively, one can make a normative judgment that conflicts (...) with the oppressive ideas one has previously been conditioned to endorse, but expressivism seems to deny that this is possible. The expressivist's inability to count these avowals made under oppression as genuine normative judgments makes expressivism deficient as a metaethical theory. (shrink)

According to the dispositional account of gender, to have a gender is to have some set of behavioral dispositions. Robin Dembroff (2020) levels a strong objection to Jennifer McKitrick’s (2015) dispositional view of gender, arguing that it can neither capture the extension of genderqueer identities nor treat them with the respect that they warrant. In this paper, I offer a defense of the dispositional view against these charges. I argue that accounts of dispositions tailored to deal with masks and finks—phenomena (...) that would prevent a disposition from manifesting or change a disposition if it were about to manifest—can avoid Dembroff’s extensional worry without reducing nonbinary identities to a matter of mere linguistic convention. I offer a revision to the dispositional account of genderqueer that incorporates Dembroff’s insights about the nature of destabilizing gender binaries. (shrink)

In this paper, we embark on the complicated discussion about the nature of vice in Virtue Ethics through a twofold approach: first, by taking seriously the claim that virtues (and certain flavours of vices) are genuinely dispositional features possessed by agents, and secondly, by employing a pluralistic attitude borrowed from Battaly’s pluralism (2008). Through these lenses, we identify three varieties of viciousness: incontinence, indifference, and malevolence. The upshot is that the notion of vice is not as categorically homogeneous as that (...) of virtue: some states of viciousness consist in interference of present virtuous dispositions, or mimicking of absent vicious ones, whereas others can be considered genuine dispositions themselves. Furthermore, this set-up can provide an interesting, albeit highly idealized story as to how, through the interference in one’s environment, one gets acquainted with vice in various degrees. Finally, this approach can be illuminating vis-à-vis Virtue Ethics in general; e.g. we can employ it to discuss more productively Johnston’s (2003) objection to Hursthouse’s (1999) account of moral conduct.

This paper develops a novel, bifocal account of trustworthiness according to which both trustworthinesssimpliciter(as in ‘Ann is trustworthy’) and trustworthiness tophi(as in ‘Ann is trustworthy when it comes to keeping your secrets’) are analysed in terms of dispositions to fulfil one's obligations. We also offer a systematic account of the relation between the two types of trustworthiness, an account of degrees of trustworthiness and comparative trustworthiness, as well as a view of permissible trustworthiness attribution.

Modal dispositionalists hold that dispositions provide the foundation of metaphysical necessity and possibility. According to the kind of modal dispositionalism that can be found in the present literature, a proposition p is possible just in case some things are disposed to be such that p. In the first part of this paper I show that combining this classic form of dispositionalism with the assumptions that the laws of nature are necessary and deterministic and that all dispositions are forward-looking in time (...) leads to the unattractive conclusion that every truth is necessary. I argue that the classic dispositionalist should be troubled by this result and in the second part of the paper I suggest a novel variant of dispositionalism that avoids it. This extended form of dispositionalism allows that some propositions are only indirectly underwritten by dispositions. (shrink)

The notion of affordance remains elusive, notwithstanding its importance for the representation of agency, cognition, and behaviors. This paper lays down a foundation for an ontology of affordances by elaborating the idea of “core affordance” which would serve as a common ground for explaining existing diverse conceptions of affordances and their interrelationships. For this purpose, it analyzes M. T. Turvey’s dispositional theory of affordances in light of a formal ontology of dispositions. Consequently, two kinds of so-called “core affordances” are proposed: (...) specific and general ones. Inspired directly by Turvey’s original account, a specific core affordance is intimately connected to a specific agent, as it is reciprocal with a counterpart effectivity (which is a disposition) of this agent within the agent-environment system. On the opposite, a general core affordance does not depend on individual agents; rather, its realization involves an action by an instance of a determinate class of agents. The utility of such core affordances is illustrated by examining how they can be leveraged to formalize other major accounts of affordances. Additionally, it is briefly outlined how core affordances can be employed to analyze three notions that are closely allied with affordances: the environment, image schemas, and intentions. (shrink)

This paper presents pretending as an enacted and fundamentally social activity. First, it demonstrates why we should think of pretense as inherently social. Then, it shows how that fact affects our theory in terms of what is needed in order to pretend. Standardly, pretense is seen as requiring a mechanism that allows one to bypass the “obvious” re- sponse to the environment in order to opt for a symbolic response; that mechanism is im- aginative and representational. This paper shows that (...) the Enactive Account of Pretense reconsiders the idea that one needs to respond to an absent environment when pretending, proposing instead that socially con- stituted perceptual affordances for play allow for non-obvious ways of responding to the present environment. The enactive account of pretense suggests that one need not posit special cognitive pretense mechanisms and mental scripts in order to account for pretend- ing, as available capacities for active perception and re-enactment of routines suffice. This paper concludes with suggestions for the kinds of cognitive skills that should be sought out to explain pretense. (shrink)

Inspired both by our ordinary understanding of the world and by reflection on science, anti-Humeanism is a growing trend in metaphysics. Anti-Humeans reject the Lewisian doctrine of Humean supervenience that the world is “just one little thing and then another”, and argue instead that dispositions, powers, or capacities provide connection and activity in nature. But how exactly are we to understand the shared commitment of this anti-Humean movement? I argue that this kind of anti-Humeanism, at its most general level, is (...) to be understood neither as a view about ontology nor about fundamentality, but rather as a specific claim about what explains what.

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)

Theists claim that God can make a causal difference in the world. That is, theists believe that God is causally efficacious, has power. Discussion of divine power has centered on understanding better the metaphysics of creation and sustenance, special intervention, governance, and providing an account of omnipotence consistent with other divine attributes, such as omnibenevolence. But little discussion has centered on what, deep down ontologically, God’s power is. I show that a number of prominent accounts of power fail to model (...) what divine power could be, and then develop an account based on teleological and primitivist accounts of power. (shrink)

In the realm of the philosophy of sounds and auditory experience there is an ongoing discussion concerned with the nature of sounds. One of the contestant views within this ontology of sound is that of the Property View, which holds that sounds are properties of the sounding objects. A way of developing this view is through the idea of dispositionalism, namely, by sustaining the theory according to which sounds are dispositional properties (Pasnau 1999; Kulvicki 2008; Roberts 2017). That portrayal, however, (...) is not sufficient, as it has not inquired the metaphysical debates about dispositions beyond the conditional analysis. In this paper, I try to advance this view by including recent developments (for instance Bird 2007; Vetter 2015) in the field of dispositionalism and I analyse whether this new version can sort out known and new objections to Property View.

Kit Fine famously objected against the idea that essence can be successfully analyzed in terms of de re necessity. In response, I want to explore a novel, interesting, but controversial modal account of essence in terms of intrinsicality and grounding. In the first section, I will single out two theoretical requirements that any essentialist theory should meet—the essentialist desideratum and the essentialist challenge—in order to clarify Fine’s objections. In the second section, I will assess Denby’s improved modal account, which appeals (...) to the notion of intrinsicality, and argue that it is untenable. In the third section, I will explain how, when combined with a modal-existential criterion, a hyperintensional account of intrinsicality—in the same vein as Bader (J Philos 110(10): 525–563, 2013) and Rosen (in: Hale and Hoffman (eds) Modality: Metaphysics, logic, and epistemology, Oxford, OUP, 2010)—can help successfully address Fine’s counterexamples. In the fourth section, I will evaluate how this novel analysis of essence stands with respect to sortal, origin, and natural kinds essentialism and discuss potential objections and difficulties.

Reflectance physicalists define reflectance as the intrinsic disposition of a surface to reflect finite-duration light pulses at a given efficiency per wavelength. I criticize the received view of dispositional reflectance (David R. Hilbert’s) for failing to account for what I call “harmonic dispersion,” the inverse relationship of a light pulse's duration to its bandwidth. I argue that harmonic dispersion renders reflectance defined in terms of light pulses an extrinsic disposition. Reflectance defined as the per-wavelength efficiency to reflect the superimposed, infinite-duration, (...) Fourier harmonics of pulses can be an intrinsic disposition of surfaces. This conclusion raises questions about mathematical realism, about which I nevertheless remain neutral. (shrink)

In this paper, I argue in favor of necessitarianism, the view that dispositions, when stimulated, necessitate their manifestations. After introducing and clarifying what necessitarianism does and does not amount to, I provide reasons to support the view that dispositions once stimulated necessitate their manifestations according to the stimulating conditions and the relevant properties at stake. In this framework, I will propose a principle of causal relevance and some conditions for the possibility of interference that allow us to avoid the use (...) of ceteris paribus clauses. I then defend necessitarianism from recent attacks raised by, among others, Mumford and Anjum, noting that the antecedent strengthening test is a test for causal relevance that raises no difficulties for necessitarianism.

I argue for the epiphenomenality of functional properties by means of thought experiments and general principles. General principles suggest that an object’s causal powers nomologically supervene on its intrinsic properties and that its functional role does not. This implies that it is possible for an object to lose its functional role without undergoing any change to its intrinsic properties or causal powers. Nor is it difficult to conceive of such scenarios. Various thought experiments are introduced for just this purpose. But (...) properties that can vary independently of an object’s causal powers in this way are epiphenomenal, for their instantiation by an object at a time makes no difference to the causal processes the object is involved in at that time. The same processes would have occurred even if such properties hadn’t been instantiated. The intrinsicness thesis is controversial, but it is not controversial that it is true of productive causation, and many believe that productive causation is the only form of mental causation worth having. Nevertheless, in the paper’s final section I consider dependence-based accounts of causation, which do not presuppose the intrinsicness of causal powers, and show that they too have difficulties accounting for the efficacy of functional properties.

A priori metaphysics has come under repeated attack by naturalistic metaphysicians, who take their closer connection to the sciences to confer greater epistemic credentials on their theories. But it is hard to see how this can be so unless the problem of theory change that has for so long vexed philosophers of science can be addressed in the context of scientific metaphysics. This paper argues that canonical metaphysical claims, unlike their scientific counterparts, cannot meaningfully be regarded as ‘approximately true,’ and (...) that this means that the epistemic progress that science arguably enjoys through episodes of theory change cannot be expected to transfer to its metaphysics. What the value of engaging in metaphysics of science before the emergence of a final theory becomes correspondingly unclear. (shrink)

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.

According to ecological psychology, animals perceive not just the qualities of things in their environment, but their affordances: in James Gibson’s words, ’what things furnish, for good or ill’. I propose a metaphysics for affordances that fits into a contemporary anti-Humean metaphysics of powers or potentialities. The goal is to connect two debates, one in the philosophy of perception and one in metaphysics, that stand to gain much from each other.

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.

Over the last few decades, philosophers and social scientists have applied the so-called powers ontology to the social domain. I argue that this application is highly problematic: many of the alleged powers in the social realm violate the intrinsicality condition, and those that can be coherently taken to be intrinsic to their bearers are arguably causally redundant. I end the paper by offering a diagnosis of why philosophers and social scientists have been tempted to think that there are powers in (...) social realm. (shrink)

Powers ontologies are currently enjoying a resurgence. This would be dispiriting news for the moderns; in their eyes, to imbue bodies with powers is to slide back into the scholastic slime from which they helped philosophy crawl. I focus on Descartes’s ‘little souls’ argument, which points to a genuine and, I think persisting, defect in powers theories. The problem is that an Aristotelian power is intrinsic to whatever has it. Once this move is accepted, it becomes very hard to see (...) how humble matter could have such a thing. It is as if each empowered object were possessed of a little soul that directs it and governs its behavior. Instead of attempting to resurrect the Aristotelian power theory, contemporary philosophers would be best served by taking their inspiration from its early modern replacement, devised by John Locke and Robert Boyle. On this view, powers are internal relations, not monadic properties intrinsic to their bearers. This move at once drains away the mysterious directedness of Aristotelian powers and solves the contemporary version of the little souls argument, Neil Williams’s ‘problem of fit.’. (shrink)

This article defends the criterion of permanence as a valid criterion for declaring death against some well-known recent objections. We argue that it is reasonable to adopt the criterion of permanence for declaring death, given how difficult it is to know when the point of irreversibility is actually reached. We claim that this point applies in all contexts, including the donation after circulatory determination of death context. We also examine some of the potentially unpalatable ramifications, for current death declaration practices, (...) of adopting the irreversibility criterion. (shrink)

In this paper, I will discuss an objection to Buck-Passing accounts of value, such as Reasons Fundamentalism. Buck-Passing views take value to be derivative of or reducible to reasons. The objection is that since there can be value in possible worlds in which there are no reasons, value must not be ontologically derivative of reasons. Thus, BP is false. In this paper, I show that by accepting a dispositionalist revision, BP can allow such worlds while maintaining that reasons are interestingly (...) prior to value, and without having to adopt any controversial metaphysics. I show this by exploring the debate over the nature of dispositions, identifying the diverse resources BP can appeal to. The paper proceeds as follows. I first explain BP. Next, I discuss a few versions of the challenge, settling on what seems to be the strongest form. Following this, I show that on many accounts of dispositions, while we should accept that particular instances of dispositions are prior to their particular manifestations, we should also accept that there is a sense in which dispositions are dependent on their manifestations. This provides BP with resources to respond to the challenge: BP can accept a dispositional revision, without committing to a theory of dispositions. Finally, I will respond to two objections. The first is about whether there are dispositions with impossible manifestations, contrary to my thesis that dispositions depend on their manifestations. The second is about whether there could be value where it would be impossible for that value to give reasons. (shrink)

This paper explores the prospects for dispositional accounts of abilities. According to so-called new dispositionalists, an agent has the ability to Φ iff they have a disposition to Φ when trying to Φ. We show that the new dispositionalism is beset by some problems that also beset its predecessor, the conditional analysis of abilities, and bring up some further problems. We then turn to a different approach, which links abilities not to motivational states but to the notion of success, and (...) consider ways of implementing that approach. Our results suggest that there are principled disanalogies between abilities and disposition which prevent any dispositional account of abilities from succeeding. (shrink)

The nomic view of dispositions holds that properties confer dispositions on their bearers with nomological necessity. The argument against nomic dispositions challenges the nomic view: if the nomic view is true, then objects don't have dispositions, but 'mimic' them. This paper presents an explication of disposition conferral which shows that the nomic view is not vulnerable to this objection.

McKitrick (2003) proposes that an object has a disposition if and only if there are a manifestation, the circumstances of the manifestation, a counterfactual true of the object, and an overtly dispositional locution referring to the disposition. A disposition is extrinsic if and only if an object has it, but a perfect duplicate of the object might not have it. I present an alternative definition that an object has a disposition if and only if a counterfactual is true of the (...) object that under a certain condition, it would interact with another object in a certain manner. There are three reasons for thinking that my definition is better than her definition. 1. Ockham’s razor favors my definition over McKitrick’s definition. My definition is consistent, while her definition is not, with Lewis’s and her definitions of intrinsic and extrinsic properties. 3. My definition goes well, while her definition does not, with our intuition that an object has a disposition even in a possible world where there is nothing but that object. (shrink)

This paper argues for a realist position in the metaphysics of aesthetic properties. Realist positions about aesthetic properties are few and far between, though sometimes developed by analogy to realism about colours. By contrast, my position is based on a disanalogy between aesthetic properties and colours. Unlike colours, aesthetic properties are perceived as relatively unsteady properties: as powers that objects have to cause a certain experience in the observer. Following on from this observation, I develop a realist account of aesthetic (...) properties as causally efficient powers, analogous to properties like fragility or poisonousness. To show how such a view can be made ontologically respectable, I draw on recent ‘dispositionalist’ accounts of powers in philosophical metaphysics. I then offer two arguments in favour of this view. First, the view matches the phenomenology of aesthetic judgement. Second, the view offers an explanation of how it is that critics can demand agreement with their aesthetic judgements. (shrink)

We take the potentialities that are studied in the biological sciences (e.g., totipotency) to be an important subtype of biological dispositions. The goal of this paper is twofold: first, we want to provide a detailed understanding of what biological dispositions are. We claim that two features are essential for dispositions in biology: the importance of the manifestation process and the diversity of conditions that need to be satisfied for the disposition to be manifest. Second, we demonstrate that the concept of (...) a disposition (or potentiality) is a very useful tool for the analysis of the explanatory practice in the biological sciences. On the one hand it allows an in-depth analysis of the nature and diversity of the conditions under which biological systems display specific behaviors. On the other hand the concept of a disposition may serve a unificatory role in the philosophy of the natural sciences since it captures not only the explanatory practice of biology, but of all natural sciences. Towards the end we will briefly come back to the notion of a potentiality in biology. (shrink)

This is a contribution to the encyclopedia of systems biology on dispositions.

I propose a semantics for a class of English predicates characteristically associated with possibility. The central idea is that such predicates are typically associated with an ordering source, and that differences among them are due to differences in their ordering sources. The ‘dispositional predicates’ that have been central to philosophical discussions are shown to be derivable as a special case from this more general class.

It is a widespread opinion that toleration, as a political practice, has merely instrumental value. The aim of this paper is to defend, on the contrary, that toleration has political value in itself. In more specific terms, I will claim that it is valuable in itself in virtue of its intrinsic relationship with democracy. Toleration is a constituent of democracy inasmuch as it is necessary for the existence of a democratic administration of political power. I will show that that relation (...) of constitution holds because toleration, through the protection of spaces of contestation to the political power, contributes to solving democracy’s inner tension resulting from its practical implementation. -/- Es una opinión extendida que la tolerancia, en cuanto práctica política, tiene valor meramente instrumental. El objetivo de este artículo es defender, por el contrario, que ella tiene valor político en sí.

La tolerancia es un constituyente de la democracia en cuanto es necesaria para que pueda existir una administración democrática del poder político. Mostraré que esa relación de constitución existe porque la tolerancia, mediante la protección de espacios de contestación al poder político, contribuye a la resolución de una tensión interna de la democracia en su implementación práctica.

In this paper, I present an argument that shows that the belief in libertarian freedom is inconsistent with two assumptions widely accepted by those who are physicalists with regard to the relation between the mental and the physical - that mental properties are distinct from physical properties, and that mental properties supervene on physical properties. After presenting the argument, I trace its implications for the question of the compatibility of libertarian free will and physicalism in general.

Sober and Elgin defend the claim that there are a priori causal laws in biology. Lange and Rosenberg take issue with this on Humean grounds, among others. I will argue that Sober and Elgin don’t go far enough – there are a priori causal laws in many sciences. Furthermore, I will argue that this thesis is compatible with a Humean metaphysics and an empiricist epistemology.

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.

Dispositionalists try to provide an account of modality—possibility, necessity, and the counterfactual conditional—in terms of dispositions. But there may be a tension between dispositionalist accounts of possibility on the one hand, and of counterfactuals on the other. Dispositionalists about possibility must hold that there are no impossible dispositions, i.e., dispositions with metaphysically impossible stimulus and/or manifestation conditions; dispositionalist accounts of counterfactuals, if they allow for non-vacuous counterpossibles, require that there are such impossible dispositions. I argue, first, that there are in (...) fact no impossible dispositions; and second, that the dispositionalist can nevertheless acknowledge the non-vacuity of some counterpossibles. The strategy in the second part is one of ‘divide and conquer’ that is not confined to the dispositionalist: it consists in arguing that counterpossibles, when non-vacuous, are read epistemically and are therefore outside the purview of a dispositional account.

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)

Intrapersonal variation due to color contrast effects has been used to argue against the following intuitive propositions about the colors: No object can be more than one determinable or determinate color of the same grade all over at the same time ; external objects are actually colored ; and the colors of objects are mind-independent. In this article, I provide a defense of Incompatibility, Realism, and Objectivism from intrapersonal variation arguments that rely on color contrast effects. I provide a novel, (...) ecumenical response to such arguments according to which typical variants are right, and which respects Incompatibility, Realism, and Objectivism, using the thesis that the colors of objects depend on the colors of objects in their surrounds.

Carl Craver’s mutual manipulability criterion aims to pick out all and only those components of a mechanism that are constitutively relevant with respect to a given phenomenon. In devising his criterion, Craver has made heavy use of the notion of an ideal intervention, which is a tool for illuminating causal concepts in causal models. The problem is that typical mechanistic models contain non-causal relations in addition to causal ones, which is why the standard concept of an ideal intervention is not (...) appropriate in that context. In this paper, I first show how top-down interventions in mechanistic models violate the conditions for ideal interventions. Drawing from recent developments in the causal exclusion literature, I then argue for extended interventionism better suited for the purposes of the new mechanist. Finally, I show why adopting such an extended account leads to the surprising consequence that an important subset of mechanistic interlevel relations comes out as causal. (shrink)

According to some philosophers, gender is a social role or pattern of behavior in a social context. I argue that these accounts have problematic implications for transgender. I suggest that gender is a complex behavioral disposition, or cluster of dispositions. Furthermore, since gender norms are culturally relative, one’s gender is partially constituted by extrinsic factors. I argue that this has advantages over thinking of gender as behavior, and has the added advantage of accommodating the possibility of an appearance/reality dissonance with (...) respect to one’s gender.

In this paper, I recommend a creature-level theory of representing. On this theory, a creature represents some entity just in case the creature adapts its behavior to that entity. Adapting is analyzed in terms of establishing new patterns of behavior. The theory of representing as adapting is contrasted with traditional causal and informational theories of mental representation. Moreover, I examine the theory in light of Putnam-Burge style externalism; I show that Putnam-Burge style externalism follows from and is explained by it. (...) I also suggest that the theory of representing as adapting easily accommodates a significant causal-explanatory role for representational content. (shrink)

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. (shrink)

In this paper, I make the case for the view that there are many different kinds of dispositions, a view I call dispositional pluralism. The reason I think that this case needs to be made is to temper the tendency to make sweeping generalization about the nature of dispositions that go beyond conceptual truths. Examples of such generalizations include claims that all dispositions are intrinsic, essential, fundamental, or natural.! In order to counter this tendency, I will start by noting the (...) extent to which it is at odds with the semantics of dispositions, according to which there are many kinds of disposition ascriptions. From there, I will try to support a metaphysical claim that there are different kinds of dispositions. To bridge the gap between semantics and metaphysics, I appeal to epistemology. I'll consider the question "when do we have good reason to believe that a disposition ascription is true?" If our disposition ascriptions are true, then we are right about what kinds of dispositions things have, and what kinds of dispositions there are. I claim that our evidence for different kinds of dispositions is on a par; we have reason to believe that various kinds of dispositions are instantiated. (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)

The elucidations and regimentations of grounding offered in the literature standardly take it to be a necessary connection. In particular, authors often assert, or at least assume, that if some facts ground another fact, then the obtaining of the former necessitates the latter; and moreover, that grounding is an internal relation, in the sense of being necessitated by the existence of the relata. In this article, I challenge the necessitarian orthodoxy about grounding by offering two prima facie counterexamples. First, some (...) physical facts may ground a certain phenomenal fact without necessitating it; and they may co-exist with the latter without grounding it. Second, some instantiations of categorical properties may ground the instantiation of a dispositional one without necessitating it; and they may co-exist without grounding it. After arguing that these may be genuine counterexamples, I ask whether there are modal constraints on grounding that are not threatened by them. I propose two: that grounding supervenes on what facts there are, and that every grounded fact supervenes on what grounds there are. Finally, I attempt to provide a rigorous formulation of the latter supervenience claim and discuss some technical questions that arise if we allow descending grounding chains of transfinite length.

We reply to recent papers by John Turri and Ben Bronner, who criticise the dispositionalised Nozickian tracking account we discuss in “Mad, Bad and Dangerous to Know.” We argue that the account we suggested can handle the problems raised by Turri and Bronner. In the course of responding to Turri and Bronner’s objections, we draw three general lessons for theories of epistemic dispositions: that epistemic dispositions are to some extent extrinsic, that epistemic dispositions can have manifestation conditions concerning circumstances where (...) their bearers fail to exist, and that contrast is relevant to disposition attributions.

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)

In this article, I critique a common claim that instrumental value is a form of extrinsic value. Instead, I offer an alternative dispositional analysis of instrumental value, which holds that instrumental value can, in certain circumstances, be an example of intrinsic value. It follows, then, that a popular account of the nature of final value – or value as an end – is false: the Moorean identification of final value with intrinsic value cannot properly distinguish between value as an end (...) and value as a means.
