Contextualism (the view that ‘knowledge’ and its variants are context-sensitive) has been supported in large part through appeal to intuitions about Keith DeRose’s Bank Cases. Recently, however, the contextualist construal of these cases has come under fire from Kent Bach and Jennifer Nagel who question whether the Bank Case subject’s confidence can remain constant in both low- and high-stakes cases. Having explained the Bank Cases and this challenge to them, I argue that DeRose has given a reasonable reply to this (...) initial challenge. However, I proceed to argue that the current stalemate can be broken. Seeking to extend the Bach-Nagel critique, I offer a novel interpretation of the Bank Cases according to which the subject’s evidence changes between low- and high-stakes cases. If I am correct, then, given the amount of support the Bank Cases have been thought to lend contextualism, the case for contextualism is seriously weakened. (shrink)

The truthmaker literature has recently come to the consensus that the logic of truthmaking is distinct from classical propositional logic. This development has huge implications for the free will literature. Since free will and moral responsibility are primarily ontological concerns (and not semantic concerns) the logic of truthmaking ought to be central to the free will debate. I shall demonstrate that counterexamples to transfer principles employed in the direct argument occur precisely where a plausible logic of truthmaking diverges from classical (...) logic. Further, restricted transfer principles (like the ones employed by McKenna, Stump, and Warfield) are as problematic as the original formulation of the direct argument. (shrink)

Direct source incompatibilism (DSI) is the conjunction of two claims: SI-F: there are genuine Frankfurt-style counterexamples (FSCs); SI-D: there is a sound version of the direct argument (DA). Eric Yang ( 2012 ) responds to a recent criticism of DSI (Campbell 2006 ). We show that Yang misses the mark. One can accept Yang’s criticisms and get the same result: there is a deep tension between FSCs and DA, between SI-F and SI-D. Thus, DSI is untenable. In this essay, we (...) use an important yet overlooked distinction between truthmakers and determiners to help drive this point home. (shrink)

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 the present paper, I offer a conceptual argument against the view that all properties are pure powers. I claim that thinking of all properties as pure powers leads to a regress. The regress, I argue, can be solved only if non-powers are admitted. The kernel of my thesis is that any attempt to answer the title question in an informative way will undermine a pure-power view of properties. In particular, I focus my critique on recent arguments in favour of (...) pure powers by the Late George Molnar and Jennifer McKitrick. The lines of defence of the friends of powers converge on what I call 'the ultimate argument for powers', viz., that current physics entails (or supports) the view that the fundamental properties (spin, mass, charge) are ungrounded powers. I take issue with this argument and make a modest suggestion: that the evidence from current physics is inconclusive. (shrink)

Humean metaphysics is characterized by a rejection of necessary connections between distinct existences. Dispositionalists claim that there are basic causal powers. The existence of such properties is widely held to be incompatible with the Humean rejection of necessary connections. In this paper I present a novel theory of causal powers that vindicates the dispositionalist claim that causal powers are basic, without embracing brute necessary connections. The key assumptions of the theory are that there are natural types of causal processes, and (...) that manifestations of powers are identified with certain kinds of causal processes. From these assumptions, the modal features of powers are explained in terms of internal relations between powers themselves and the process-types in which powers are manifested. (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.

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.

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)

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.

Semantic dispositionalism is roughly the view that meaning a certain thing by a word, or possessing a certain concept, consists in being disposed to do something, e.g., infer a certain way. Its main problem is that it seems to have so many and disparate exceptions. People can fail to infer as required due to lack of logical acumen, intoxication, confusion, deviant theories, neural malfunctioning, and so on. I present a theory stating possession conditions of concepts that are counterfactuals, rather than (...) disposition attributions, but which is otherwise similar to inferentialist versions of dispositionalism. I argue that it can handle all the exceptions discussed in the literature without recourse to ceteris paribus clauses. Psychological exceptions are handled by suitably undemanding requirements (unlike that of giving the sum of any two numbers) and by setting the following two preconditions upon someone’s making the inference: that she considers the inference and has no motivating reason against it. The non-psychological exceptions, i.e., cases of neural malfunctioning, are handled by requiring that the counterfactuals be true sufficiently often during the relevant interval. I argue that this accommodates some important intuitions about concept possession, in particular, the intuition that concept possession is vague along a certain dimension. (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.

Nonreductive physicalism faces serious problems regarding causal exclusion, causal heterogeneity, and the nature of realization. In this paper I advance solutions to each of those problems. The proposed solutions all depend crucially on embracing modal counterpart theory. Hence, the paper’s thesis: counterpart theory saves nonreductive physicalism. I take as my inspiration the view that mental tokens are constituted by physical tokens in the same way statues are constituted by lumps of clay. I break from other philosophers who have pursued this (...) line, however, in that I hold that constitution is identity. Much of the value of the comparison to statues and lumps is that it calls to mind the resources used to defend constitution-as-identity, most notably that of counterpart theory. Along the way, I discuss the virtues of a trope ontology, modal objections to token identity theories, the prospects of conditional analyses of causal powers, the subset account of realization, and the grounding problem. I also endorse a novel, empirical argument in favor of counterpart theory. (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)

Lewis claims that Martin’s cases indeed refute the simple conditional analysis of dispositions and proposes the reformed conditional analysis that is purported to overcome them. In this paper I will first argue that Lewis’s defense of the reformed analysis can be understood to invoke the concepts of disposition-specific stimulus and manifestation. I will go on to argue that advocates of the simple analysis, just like Lewis, can also defend their analysis from alleged counterexamples including Martin’s cases by invoking the concepts (...) of disposition-specific stimulus and manifestation. This means that Lewis’s own necessary defense of the reformed analysis invalidates his motivation of it. Finally, I will argue that we have a good reason to favor the simple analysis over Lewis’s analysis. (shrink)

The Simple Counterfactual Analysis (SCA) was once considered the most promising analysis of disposition ascriptions. According to SCA, disposition ascriptions are to be analyzed in terms of counterfactual conditionals. In the last few decades, however, SCA has become the target of a battery of counterexamples. In all counterexamples, something seems to be interfering with a certain object’s having or not having a certain disposition thus making the truth-values of the disposition ascription and of its associated counterfactual come apart. Intuitively, however, (...) it would seem that, if all interferences were absent, the disposition ascription and its associated conditional would have the same truth-value. Although this idea may seem obvious, it is far from obvious how to implement it. In fact, it has become widely assumed that the content of qualifying ceteris paribus clauses (such as ‘if all interferences were absent’) cannot be specified in a clear and non-circular manner. In this paper, I will argue that this assumption is wrong. I will develop an analysis of disposition ascriptions, the Interference-Free Counterfactual Analysis, which relies on a clear and non-circular definition of the notion of interference and avoids the standard counterexamples to SCA while vindicating the intuition that disposition ascriptions and counterfactual conditionals are intimately related. (Please note that an erratum has been issued for the published version of this paper. It is recommended to read the self-archived version of the paper.). (shrink)

A number of authors have suggested that a conditional analysis of dispositions must take roughly the following form: Thing X is disposed to produce response R to stimulus S just in case, if X were exposed to S and surrounding circumstances were auspicious, then X would produce R. The great challenge is cashing out the relevant notion of ‘auspicious circumstances’. I give a general argument which entails that all existing conditional analyses fail, and that there is no satisfactory way to (...) define ‘auspicious circumstances’ just in terms of S, R, and X. Instead, I argue that the auspicious circumstances C for the manifestation of a disposition constitute a third irreducible element of that disposition, and that to pick out (or to ‘individuate’) that disposition one must specify C along with S and R. This enables a new conditional analysis of dispositions that gives intuitively satisfying answers in cases that pose problems for other approaches. (shrink)

In this paper, I investigate the prospects for using the distinction between rejection and denial to resolve Saul Kripke’s puzzle about belief. One puzzle Kripke presents in A Puzzle About Belief poses what would have seemed a fairly straightforward question about the beliefs of the bilingual Pierre, who is disposed to sincerely and reflectively assent to the French sentence Londres est jolie, but not to the English sentence London is pretty, both of which he understands perfectly well. The question to (...) be answered is whether Pierre believes that London is pretty, and Kripke argues, of each answer, that it is unacceptable. On my proposal, either answer to the question is to be rejected, but neither answer is to be denied, using the resource of partially-defined predicates. After demonstrating how this serves as a solution to the puzzle, I illustrate some philosophical motivations—independent of Kripke’s puzzle —for adopting a view on which belief is a partially defined predicate. I conclude that there are decent prospects for the proposed response to Kripke’s puzzle. (shrink)

This paper discusses Lee’s argument that Lewis’s reformed conditional analysis of dispositions is preferable to the simple conditional analysis of dispositions. Lee’s argument is basically that there are some examples that can be adequately handled by Lewis’s analysis but cannot by the simple conditional analysis of dispositions. But I will reveal that, when carefully understood, they spell no trouble for the simple conditional analysis of dispositions, failing to serve a motivating role for Lewis’s analysis.

The expression conditional fallacy identifies a family of arguments deemed to entail odd and false consequences for notions defined in terms of counterfactuals. The antirealist notion of truth is typically defined in terms of what a rational enquirer or a community of rational enquirers would believe if they were suitably informed. This notion is deemed to entail, via the conditional fallacy, odd and false propositions, for example that there necessarily exists a rational enquirer. If these consequences do indeed follow from (...) the antirealist notion of truth, alethic antirealism should probably be rejected. In this paper we analyse the conditional fallacy from a semantic (i.e. model-theoretic) point of view. This allows us to identify with precision the philosophical commitments that ground the validity of this type of argument. We show that the conditional fallacy arguments against alethic antirealism are valid only if controversial metaphysical assumptions are accepted. We suggest that the antirealist is not committed to the conditional fallacy because she is not committed to some of these assumptions. (shrink)

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.

Suppose dispositions bear a distinctive connection to counterfactual facts, perhaps one that could be enshrined in a variation on the well-worn schema "Necessarily, x is disposed to phi in psi iff x would phi in psi. Could we exploit this connection to provide an account of what it is to be a disposition? This paper is about four views of dispositionality that attempt to do so.

For the last several decades, dispositional properties have been one of the main topics in metaphysics. Still, however, there is little agreement among contemporary metaphysicians on the nature of dispositional properties. Apparently, though, the majority of them have reached the consensus that dispositional ascriptions cannot be analysed in terms of simple counterfactual conditionals. In this paper it will be brought to light that this consensus is wrong. Specifically, I will argue that the simple conditional analysis of dispositions, which is generally (...) thought to be dead, is in fact an adequate analysis of dispositions. I will go on to discuss Mumford’s view of dispositions from the perspective of the simple conditional analysis of dispositions. (shrink)

This is an essay on the understanding of disposition concepts, which exploits the Ramsey test semantics of conditionals for a refined conditional analysis of dispositions. I will show that this semantics allows for a more accurate account of disposition concepts than the standard semantics of conditionals by David Lewis. This includes dealing with the counterexamples to the conditional analysis, which are known as finks, antidotes, and mimics.

This paper explores the debate between those philosophers who take (fundamental, perfectly natural) properties to be pure powers and those who take them to be powerful qualities. I first consider two challenges for the view that properties are powerful qualities, which I call, respectively, ‘the clarification challenge’ and ‘the explanatory challenge’. I then examine a number of arguments that aim to show that properties cannot be pure powers and find them all wanting. Finally, I sketch what I take to be (...) the most promising argument against pure powers and for powerful qualities. (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)

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.

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)

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)

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.

If one’s solution to the free will problem is in terms of real causal powers of agents then one ought to be an incompatibilist. Some premises are contentious but the following new argument for incompatibilism is advanced: 1. If causal determinism is true, all events are necessitated2. If all events are necessitated, then there are no powers3. Free will consists in the exercise of an agent’s powersTherefore, if causal determinism is true, there is no free will; which is to say (...) that free will is incompatible with determinism, so compatibilism is false.

Response-dependence theses are usually formulated in terms of a priori true biconditionals of roughly the form 'something, x, falls under the concept 'F' ↔ x would elicit response R from subjects S under conditions C'. Such formulations are vulnerable to conditional fallacy problems; counterexamples threaten whenever the C-conditions' coming to obtain might alter the object with respect to F. Crispin Wright has suggested that such problems can be avoided by placing the C-conditions in a proviso. This ensures that any changes (...) triggered by the C-conditions' coming to obtain will be irrelevant to the truth of the biconditional. I argue that this move leaves the equations vulnerable to counterexamples of a slightly different kind: Cases where the change is triggered, not by the C-conditions' coming to obtain, but by the response. I consider two ways to resist these counterexamples, and argue that both are insufficient. The upshot is a challenge that must be met if provisoed biconditionals are to serve their purpose. (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. (shrink)

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.

Attempts to capture the distinction between categorical and dispositional states in terms of more primitive modal notions – subjunctive conditionals, causal roles, or combinatorial principles – are bound to fail. Such failure is ensured by a deep symmetry in the ways dispositional and categorical states alike carry modal import. But the categorical/dispositional distinction should not be abandoned; it underpins important metaphysical disputes. Rather, it should be taken as a primitive, after which the doomed attempts at reductive explanation can be transformed (...) into circular but interesting accounts. (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)

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)

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)

According to Nozick’s tracking theory of knowledge, an agent a knows that p just in case her belief that p is true and also satisfies the two tracking conditionals that had p been false, she would not have believed that p , and had p been true under slightly different circumstances, she would still have believed that p . In this paper I wish to highlight an interesting but generally ignored feature of this theory: namely that it is reminiscent of (...) a dispositional account of knowledge: it invites us to think of knowledge as a manifestation of a cognitive disposition to form true beliefs. Indeed, given a general account of dispositions in terms of subjunctive conditionals, the two tracking conditionals are satisfied just in case the belief in question results from some cognitive disposition to form true beliefs. Recently, such a conditional account of dispositions has, however, been criticised for its vulnerability to so-called ‘masked’, ‘mimicked’ and ‘finkish’ counterexamples. I show how the classical counterexamples to Nozick’s theory divide smoothly into four corresponding categories of counterexamples from epistemic masking, mimicking and finkishness. This provides strong evidence for the thesis that satisfaction of the two tracking conditionals is symptomatic of knowledge and that knowledge is instead constituted by a dispositional capability to form true beliefs. The attempt to capture such a cognitive, dispositional capability in terms of the tracking conditionals, although providing a good approximation in a wide variety of cases, still comes apart from the real thing whenever the epistemic layout is characterised by masking-, mimicking- and finkish mechanisms. In the last part of the paper I explore the prospect of improving the tracking theory in the light of these findings. (shrink)

It is argued that the so‐called principles of “strong centering” and “weak centering” central to the traditional Lewis‐Stalnaker semantics for counterfactuals are both fallacious. A foundation for an alternative semantics without these prinsciples is outlined. The core idea is that the statistically normal worlds – rather than those worlds most qualitatively similar to the actual world – should serve as the semantical fulcrum.

Are counterfactuals with true antecedents and consequents trivially true? The principle of Conjunction Conditionalization →) is highly controversial. Many philosophers view it as an attractive feature of Lewis’s semantics for counterfactuals that it can easily be modified to avoid this principle. However, Walters and Williams beg to differ. They argue that Conjunction Conditionalization is an indispensable ingredient of any Lewisian semantics, since CC is entailed by standard Lewisian theorems and a plausible semantic claim about irrelevant semifactuals. If this is true, (...) the entire tradition of revisionist counterfactual semantics is misguided, and so are many philosophical theories in which counterfactuals play a role. We argue, in defense of the revisionist tradition, that Walters and Williams’ ‘plausible semantic claim’ is in fact anything but plausible. It turns out to entail semantic principles far more controversial than Conjunction Conditionalization. (shrink)

George Molnar’s contention that some dispositional properties are displayed without the aid of any activating conditions poses a challenge to the conditional analysis of dispositions. Since the invocation of activating conditions is regarded as a crucial feature of the analysis, spontaneous dispositions are believed to expose its inadequacy by eluding its scope. The challenge goes to the very heart of the conditional approach to dispositions, allegedly revealing a deep flaw in all its incarnations. Granting that there may be spontaneously manifestable (...) dispositions, I argue that the conditional analysis can successfully accommodate them by elevating the potential causal relation between a disposition and its manifestation.

According to the Simple Conditional Analysis of disposition ascriptions, disposition ascriptions are to be analyzed in terms of counterfactual conditionals. The Simple Conditional Analysis is notoriously vulnerable to counterexamples. In this paper, I introduce a new sort of counterexample to the Simple Conditional Analysis of disposition ascriptions, which I call ‘tricks’. I then explore a number of possible strategies to modify the Simple Conditional Analysis so as to avoid tricks and conclude that, in order to avoid tricks, the associated counterfactual (...) should be evaluated at the closest possible world at which the manifestation of the disposition does not obtain.

In a recent paper Lee Walters criticizes a number of philosophers – including Gundersen – for committing a ‘failure in the argumentative strategy’ when they attempt to amend the standard Lewis semantics for counterfactuals in order to avoid the so‐called principle of Conjunction Conditionalization. In this article we defend a Gundersen‐style probability‐based semantics against Walter's major misgivings: that it is not logically conservative, that it is committed to the Connection Hypothesis, and that it cannot deal satisfactory with irrelevant semi‐factuals.
