There is no consensus on the most adequate conception of the fundamental properties of our world. The pure powers view and the identity theory of powerful qualities claim to be promising alternatives to categoricalism, the view that all fundamental properties essentially contribute to the qualitative make-up of things that have them. The pure powers view holds that fundamental properties essentially empower things that have them with a distinctive causal profile. On the identity theory, fundamental properties are dispositional as well as (...) qualitative, or powerful qualities. Despite the manifest difference, Taylor (2018) argues that pure powers and powerful qualities collapse into the same ontology. If this collapse objection were sound, the debate between the pure powers view and the identity theory of powerful qualities would be illusory: these views could claim the same advantages and would suffer the same problems. Here I defend an ontologically robust distinction between pure powers and powerful qualities. To accomplish this aim, I show that the collapse between pure powers and powerful qualities can be resisted. I conclude by drawing some positive implications of this result. (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. (shrink)

Necessitarianism, as we shall use the term, is the view that natural properties and causal powers are necessarily connected in some way. In recent decades the most popular forms of necessitarianism have been the anti-Humean powers-based theories of properties, such as dispositional essentialism and the identity theory. These versions of necessitarianism have come under fire in recent years and I believe it is time for necessitarians to develop a new approach. In this paper I identify unexplored ways of positing metaphysically (...) necessary connections in nature, using the concepts of grounding and essential dependence. For example, I show that one could be a necessitarian by insisting that the properties of things necessarily ground their powers, and that one can maintain this while rejecting dispositional essentialism. Using different combinations of claims about grounding and essential dependence, I map out a spectrum of new positions and compare them to previous theories of natural modality. Some of these positions are compatible with Humean metaphysics while others are not. The overall aim of the paper is to provide a new metaphysical framework for understanding theories of powers and thereby launch a new necessitarian research programme. (shrink)

After identifying some existing explanations offered by nomic necessitarians for the alleged necessary connections between natural properties and their dispositional or nomic features, I discuss a less explored necessitarian strategy. This strategy is available to Platonists who hold that properties exist necessarily, as most do.

In this paper I argue that if one subscribes to dispositionalism — the view that natural properties are irreducibly dispositional in character — then one ought to favour a Platonic view of properties. That is, dispositionalists ought to view properties as transcendent universals. I argue for this on the grounds that only with transcendent universals in play can two central dispositionalist platitudes be accounted for in a satisfactory way. Given that dispositionalism is becoming an increasingly influential view in the metaphysics (...) of science, my argument, if successful, suggests that Platonism will see something of a revival in contemporary metaphysics. This new kind of Platonism is shown to have some striking metaphysical and epistemological consequences. (shrink)

Notoriously, the dispositional view of natural properties is thought to face a number of regress problems, one of which points to an epistemological worry. In this paper, I argue that the rival categorical view is also susceptible to the same kind of regress problem. This problem can be overcome, most plausibly, with the development of a structuralist epistemology. After identifying problems faced by alternative solutions, I sketch the main features of this structuralist epistemological approach, referring to graph-theoretic modelling in the (...) process. Given that both the categoricalists and dispositionalists are under pressure to adopt this same epistemological approach in light of the regress problem, this suggests that the categoricalist versus dispositionalist debate is best fought on metaphysical rather than epistemological grounds. (shrink)

Dispositional realism, as we shall use the term, is a non-reductive, anti-Humean approach to dispositions which says that natural properties confer certain dispositions as a matter of metaphysical necessity. A strong form of dispositional realism is known as pan-dispositionalism, which is typically interpreted as the view that all natural properties are identical with, or essentially dependent on, dispositions. One of the most serious problems facing pan-dispositionalism is the conceivability objection, and the solution commonly offered by essentialists employs the so-called redescription (...) strategy. In this paper I argue that this orthodox strategy fails in certain cases. This argument, in turn, shows that essentialist forms of dispositional realism are implausible. The discussion points us towards an improved version of dispositional realism. According to this new version, natural properties are not essentially dispositional but necessarily ground dispositions. (shrink)

Many think that properties are powers. However, whilst some claim that properties are pure powers, others claim that properties are powerful qualities. In this paper, I argue that the canonical formulation of the powerful qualities view is no different from the pure powers view. Contrary to appearances, the two positions accept the same view of properties. Thus, the debate between them rests on an illusion. I draw out some consequences of this surprising result for issues over property individuation. Along the (...) way, I argue that all existing objections to the powerful qualities view fail. (shrink)

David Chalmers’ ‘conceivability’ argument against physicalism is perhaps the most widely discussed and controversial argument in contemporary philosophy of mind. Recently, several thinkers have suggested a novel response to this argument, which employs the ‘powerful qualities’ ontology of properties. In this paper, I argue that this response fails because it presupposes an implausible account of the physical/phenomenal distinction. In the course of establishing this, I discuss the so-called ‘ultimate’ argument for the claim that dispositional properties form the subject matter of (...) physics. I argue that the ultimate argument can be interpreted in a strong or a weak way, and that the strong interpretation is implausible. I argue that this undermines the powerful qualities based response to the conceivability argument. I also argue for a general conclusion: that we should not define ‘the physical’ exclusively in terms of a distinction drawn from ontology. (shrink)

[full article, abstract in English; abstract in Lithuanian] Armstrong’s theory of laws and causation may be articulated as something like the following, which we may refer to as the received view: “Laws are intrinsic higher-order relations of ensuring between properties. The instantiation of laws is identical with singular causation. This identity is a posteriori.” Opponents and advocates of this view, believe that it may fairly and correctly be attributed to Armstrong. I do not deny it; instead I seek to reconsider (...) the received view, specifically by treating it as a part of Armstrong’s metaphysics. The main features that should concern us are truthmaker theory and the formal account of the constitutive parts of states of affairs. I also discuss Bird’s ultimate argument against Armstrong and show how its impact is weakened by this proper reading. (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)

Categoricalism is a doctrine about properties according to which the dispositional aspects of properties are not essential to them. In opposition to categoricalism, dispositionalism holds that the dispositional aspects of properties are essential to them. In this article, I shall construct a new version of categoricalism that should be favoured over the other existing versions: Semi-Necessitarian Categoricalism. In Section 2 I shall elaborate on the distinction between categoricalism and dispositionalism and single out different ‘shades’ of both doctrines. I shall also (...) illustrate the main advantages and problems that characterize categoricalism. In Section 3 I shall introduce Necessitarian Categoricalism—as it has been recently developed by Alexander Kelly and Deborah Smith, among others. Even if Necessitarian Categoricalism solves the aforementioned problems of categoricalism, it also loses its main advantages. In Section 4 I shall refine this version of Necessitarian Categoricalism, thus developing Semi-Necessitarian Categoricalism. In Section 5 I shall face some objections. Finally, in Section 6, I shall briefly draw some conclusions and compare my account with other accounts. (shrink)

The Identity Theory of properties (IDT) is an increasingly popular metaphysical view that aims to be a middle way between pure powerism and pure categoricalism. This paper’s goal is to highlight three major difficulties that IDT should address in order to be a plausible account of the nature of properties. First, although IDT needs a clear definition of the notion of qualitativity which is both adequate and compatible with the tenets of the theory, all the extant proposals fail to provide (...) such a definition. Second, the suggested definitions of qualitativity are characterised by a metaphysical ‘neutrality’ that threatens to trivialise the important metaphysical debate regarding the question whether properties confer by themselves dispositions on their bearers (and so they are inherently modal and active) or need the ‘assistance’ of laws of nature to do that. Finally, none of the extant alternative understandings of the core identity-claim of IDT can adequately meet the objection that the claim in question is unintelligible. (shrink)

Dispositional Essentialism is a unified anti-Humean account of the metaphysics of low-level physical properties and laws of nature. In this paper, I articulate the view that I label Canonical Dispositional Essentialism, which comprises a structuralist metaphysics of properties and an account of laws as relations in the property structure. I then present an alternative anti-Humean account of properties and laws. This account rejects CDE’s structuralist metaphysics of properties in favour of a view of properties as qualitative grounds of dispositions and (...) it rejects CDE’s view of laws as relations in favour of a view of laws as features of an efficient description of possible property distributions. I then defend this view over CDE on the grounds that it can overcome an explanatory shortcoming of CDE and that it achieves a level of continuity with science that CDE fails to achieve. The upshot of this paper is a significant narrowing of the range of possibilities in which the absolutely best unified account of laws and properties resides. (shrink)

Some philosophers maintain that physical properties are irreducibly modal: that properties are powers. Powers are then employed to provide explanations of other phenomena of philosophical interest such as laws of nature and modality. There is, however, a dispute among powers theorists about how far the powers ontology extends: are all manner of properties at all levels of fundamentality powers or are powers only to be found among the fundamental properties? This paper argues that the answer to this question depends on (...) the details of the metaphysics of powers. More specifically, this paper argues that if one understands powers as qualitative grounds of dispositions, as opposed to properties whose essences are constituted by dispositions, then all properties, be they fundamental or macro, are powers, i.e., pandispositionalism is true. The Conclusion: If qualitative dispositional essentialism is true, then pandispositionalism is true, is significant because there is increasing concern that orthodox dispositional essentialism is explanatorily deficient and perhaps even incoherent, meaning that qualitative dispositional essentialism is gaining increasing support in the literature on powers. All things considered, then, it is beginning to look more likely that pandispositionalism is true simpliciter. (shrink)

Stephen Mumford and Alexander Bird disagree about which properties are powers and, correspondingly, about the extent of the philosophical work to which powers may be put. Unfortunately, there is an important respect in which these authors are talking past each other and so the reason for their disagreement remains obscured. I highlight what has gone wrong in their recent exchange, attempt to clear up the confusion and pinpoint the true source of their disagreement. My hope is to redirect the efforts (...) of these authors and their followers onto more pressing foundational issues in the metaphysics of powers. (shrink)

According to dispositionalism, fundamental properties are dispositions—powers that don’t reduce to other properties, laws, or anything else. As dispositions manifest, natural regularities result, so this view appears to explain the uniformity of nature. However, in this paper I’ll argue that there are types of regularities that can’t be explained by dispositionalism. The basic idea is this. All accounts of fundamental dispositions endow properties with a certain sort of structure. This allows explanations of only those regularities that align with such structures. (...) In this paper, I identify a type of natural regularity that cannot fit dispositionalist structures and show why the possibility of such regularities is problematic. (shrink)

Dispositional essentialism is the view that all or many fundamental properties are essentially dispositional, orpowers. The literature on the dispositional essence of powers is abundant. In contrast, the question of how to understand the fundamentality of fundamental powers has received scarce interest. Therefore, the fundamentality of powers stands in need of clarification. There are four main conceptions of the fundamental, namely as that which is (i)metaphysically independent; or (ii)belonging to a minimally complete basis; or (iii)perfectly natural; or (iv)metaphysically primitive. Here, (...) I present and discuss each of these approaches from the viewpoint of dispositional essentialism. I show that (i) is incompatible with the metaphysics of powers and (ii)–(iv) have more drawbacks than merits. Therefore, my conclusion is that the dispositional essentialist should seek an alternative. Although I offer no positive account, I pave the way to more fruitful views by identifying the shortcoming of these unpromising options. (shrink)

Establishing Dispositionalism as a viable theory of modality requires the successful fulfilment of two tasks: showing that all modal truths can be derived from truths about actual powers, and offering a suitable metaphysics of powers. These two tasks are intertwined: difficulties in one can affect the chances of success in the other. In this paper, I generalise an objection to Dispositionalism by Jessica Leech and argue that the theory in its present form is ill-suited to account for de re truths (...) about merely possible entities. I argue that such difficulty is rooted in a problem in the metaphysics of powers. In particular, I contend that the well-known tension between two key principle of powers ontology, namely Directedness and Independence has received an unsatisfactory solution so far, and that it is this unsatisfactory solution concerning the status of “unmanifested manifestations” that makes it hard for Dispositionalism to account for mere possibilia. I develop a novel account of the status of unmanifested manifestations and an overall metaphysics of powers which allows to better respond to Leech's objection and handle mere possibilia. The central idea of the proposal is that unmanifested manifestations are akin to mere logical existents, and are best characterised as non-essentially non-located entities. (shrink)

Bird’s Ultimate Argument sought to show that Armstrong’s N relationships involving categorical universals can’t entail nomic regularities. In N’s place Bird offered the non-categorical SR relation. Two kinds of objection have been raised: either Bird’s own alternative metaphysics fails in just the same way as Armstrong’s or the target of Bird’s argument may anyway have a way out of the problem. My aim is to reclaim the victory for Bird. I argue that the responses in defence of Armstong’s N relationships (...) fail to acknowledge that Bird was explicitly concerned with Armstrong’s commitment to a categoricalist view of universals. Moreover, Bird’s alternative account does not suffer the same problem since his metaphysics of properties is essentialist. Nevertheless, Bird’s account does need elaborating on to explainwhySR relationships entail their regularities. I offer Schaffer’s Axiomatic Solution as a candidate for this purpose. (shrink)

Can the desire for efficiently systematised theories in science be explained from within a powers metaphysics? It is plausible that the traditional ‘Powers Theory of Laws’, endorsed by many friends of powers, does not alone provide such an explanation. This has led a number of recent authors to argue that a ‘Powers Best System Account’ of laws would be a preferable alternative. This account borrows a method for determining laws from the Humean and applies it to a reality of powers. (...) Here I claim, to the contrary, that this account is both internally unworkable and, anyway, completely undermotivated when compared with the traditional view. Apart from some brief suggestions for alternative accounts, I’ll conclude that the powers theorist still has their work cut out to explain systematising in science. (shrink)

The aim of this paper is to motivate a view on dispositions according to which dispositions and their manifestations are partially identical, the DM identity theory. It sets out by extrapolating the desiderata of a dispositionalist account of properties. It then shows that the previous theories are burdened with different problems, whose common cause, so the argument goes, is the separation assumption, which almost all share. It states that dispositions and their manifestations are numerically distinct. The paper then explores whether (...) the separation assumption can be abandoned and shows that there are precursors of a DM identity theory. The DM identity theory is then outlined in its central features and it is outlined how they can fulfil the desiderata of dispositionalism. (shrink)

The deep differences between E. J. Lowe’s ontology of dispositions and that maintained by other prominent dispositionalists have received relatively little attention in the existing literature on his work. Here I lay out some of these differences, along the way attempting to clarify whether Lowe’s ontology can properly be termed ‘dispositionalist.’ I then argue that the unique features of his ontology allow it to avoid some well-known worries facing standard dispositionalism, while at the same time opening his view to novel (...) objections. My overall aim here is neither to defend nor attack Lowe’s theory, but rather to assess some of its pros and cons and to consider its sometimes surprising implications (implications not always drawn out explicitly by Lowe). (shrink)

Individuals are often the subject of generalizations of various special sciences. The traditional argument is that there can't be laws about such individuals, since the law statements would have to contain local predicates. Marc Lange argues that, despite local predication, there can be laws about individuals. This paper argues, on the contrary, that there can be no such laws – not because of local predication, but because the laws would discriminate among material systems on non-qualitative grounds. I rely on the (...) principle that qualitatively identical systems under one set of laws must evolve in the same manner. If there could be laws about individuals, nothing would guarantee that the principle is satisfied. My argument is illustrated by a thought experiment inspired by Strawson's massive reduplication argument. (shrink)

According to a well-known argument, originally due to David Armstrong, powers theory is objectionable, as it leads to a ‘Meinongian’ ontology on which some entities are real but do not actually exist. I argue here that the right conclusion to draw from this argument has thus far not been identified and that doing so has significant implications for powers theory. Specifically, I argue that the key consequence of the argument is that it provides substantial grounds for trope powers theorists, but (...) not other powers theorists, to accept one version of the view that properties are powerful qualities. In particular, they have grounds to favour the view that powerful properties are properties with exclusively qualitative natures that ground modal facts. (shrink)

According to a well-known argument against dispositional essentialism, the nature of unmanifested token powers leaves dispositional essentialists with an objectionable commitment to the reality of non-existent entities. The idea is that, because unmanifested token powers are directed at their non-existent token manifestations, they require the reality of those manifestations. Arguably the most promising response to this argument works by claiming that, if properties are universals, dispositional directedness need only entail the reality of actually existing manifestation types. I argue that this (...) response fails, because no version of the response can adequately accommodate dispositions of the sort that follow from Coulomb’s law. This result both defeats an important argument that dispositional essentialists ought to be realists about universals and appears to leave dispositional essentialists with a problematic commitment to either non-relational connections or a Meinongian ontology. (shrink)

A recent, seemingly appealing version of the powerful qualities view defines properties’ qualitativity via an essentialist claim and their powerfulness via a grounding claim. Roughly, this approach holds that properties are qualities because they have qualitative essences, while they are powerful because their instances or essences ground causal-modal facts. I argue that this theory should be replaced with one that defines the powerfulness of qualities in terms of both a grounding claim and a ‘meta-grounding’ claim. Specifically, I formulate and defend (...) a view on which qualities are powerful just if instances of those qualitiesat least partiallyground dispositionsin virtue of the essences of those qualities. (shrink)

According to the powerful qualities view, properties are both powerful and qualitative. Indeed, on this view the powerfulness of a property is identical to its qualitativity. Proponents claim that this view provides an attractive alternative to both the view that properties are pure powers and the view that they are pure qualities. It remains unclear, however, whether the claimed identity between powerfulness and qualitativity can be made coherent in a way that allows the powerful qualities view to constitute this sort (...) of alternative. I argue here that this can be done, given a particular conception of both the qualitativity and powerfulness of properties. On this conception, a property is qualitative just in the sense that its essence is fixed independently of any distinct properties, and it is powerful just if its essence grounds its dispositional role. (shrink)

Discussions about the nature of essence and about the inference problem for non-Humean theories of nomic modality have largely proceeded independently of each other. In this article I argue that the right conclusions to draw about the inference problem actually depend significantly on how best to understand the nature of essence. In particular, I argue that this conclusion holds for the version of the inference problem developed and defended by Alexander Bird. I argue that Bird’s own argument that this problem (...) is fatal for David Armstrong’s influential theory of the laws of nature but not for dispositional essentialism is seriously flawed. In place of this argument, I develop an argument that whether Bird’s inference problem raises serious difficulties for Armstrong’s theory depends on the answers to substantial questions about how best to understand essence. The key consequence is that considerations about the nature of essence have significant, underappreciated implications for Armstrong’s theory. (shrink)

This paper argues that the new metaphysics of powers, also known as dispositional essentialism or causal structuralism, is an illusory metaphysics. I argue for this in the following way. I begin by distinguishing three fundamental ways of seeing how facts of physical modality — facts about physical necessitation and possibility, causation, disposition, and chance — are grounded in the world. The first way, call it the first degree, is that the actual world or all worlds, in their entirety, are the (...) source of physical modality. Humeanism is the best known such approach, but there are other less well-known approaches. The second way, the second degree, is that the source of physical modality lies in certain second-order facts, involving a relation between universals. Armstrong’s necessitarianism and other views are second-degree views. The third way, the third degree, holds that properties themselves are the source of physical modality. This is the powers view. I examine four ways of developing the third degree: relational constitution, graph-theoretic structuralism, dispositional roles, and powerful qualities. All these ways are either incoherent, or just disguised versions of the first-degree. The new metaphysics of powers is illusory. With the collapse of the third degree, the second degree, the necessitarian view of law, collapses as well. I end the paper with some reflections on the first degree, on the problem of explaining necessary connections between distinct existences, and on the dim prospects of holist ontology. (shrink)

This paper draws a number of parallels between Schelling’s Naturphilosophie and contemporary work in the metaphysics of powers. This concept is being applied to a range of debates, however a distinct lack of work exists focusing on extending this concept to ontology as a whole. I argue that Schelling’s Naturphilosophie provides insight into what this kind of system would look like. I begin with a brief outline of the characterisation and use of powers in the contemporary literature to show the (...) marked similarities between these accounts and Schelling’s. I then present my reading of the Naturphilosophie as a power-based ontology, and gesture towards some ways in which this account could help to fill some of the gaps in the current literature. Because of the centrality of powers to the Naturphilosophie, and because of the holistic nature of Schelling’s work, the role of powers and relationship of powers to a range of other concepts is carefully specified here. Thus a number of the implications and advantages of this kind of view are already worked out and presented in the texts on Naturphilosophie. Finally, I argue that Schelling’s Naturphilosophie also demonstrates some possible problems that will arise for any ontology of this kind. (shrink)

Dispositional essentialism is a non-Humean view about the essences of certain fundamental or natural properties that looms large in recent metaphysics , not least because it promises to explain neatly the natural modalities such as laws of nature, counterfactuals, causation and chance. In the current paper, however, several considerations are presented that indicate a serious tension between its essentialist core thesis and natural “metaphysical” interpretations of its central explanatory claims.
