One powerful argument for dualism is provided by Chalmers: the ‘zombie’ or conceivability argument. This paper aims to establish that if one adopts the ‘Powerful Qualities’ account of properties developed by Martin and Heil, this argument can be resisted at the first premise: the claim that zombies are conceivable is, by the lights of Chalmers’ own account of conceivability, false. The Powerful Qualities account is outlined. Chalmers’ argument, and several distinctions which underlie it, are explained. It is argued that to (...) make sense of the claim that zombies are conceivable, some account of properties must be given. The paper’s central claim is presented and defended from potential responses: given the Powerful Qualities view, zombies are in fact inconceivable. Finally, an error theory is presented, which offers an explanation of why so many have taken the conceivability of zombies to be unproblematic, and the view is briefly contrasted with Russellian monism.

Over the last decade or so, there has been a renewed interest in a view about properties known as quidditism. However, a review of the literature reveals that ‘quidditism’ is used to cover a range of distinct views. In this paper I explore the logical space of distinct types of quidditism. The first distinction noted is between quidditism as a thesis explicitly about property individuation and quidditism as a principle of unrestricted property recombination. The distinction recently drawn by Dustin Locke (...) between extravagant quidditism and austere quidditism is a distinction between quidditisms of the first type. It is then argued that austere quidditism may itself be further sub-divided into what I call ‘extremely austere quidditism’ and ‘moderately austere quidditism’. Moderately austere quidditism is argued to be preferable to extremely austere quidditism and further to be able to address many of the arguments leveled against quidditism in general. (shrink)

The paper sketches out an ontology of physics in terms of matter being primitive stuff distributed in space and all the properties physics is committed to being dispositions that fix the temporal development of the distribution of matter in space. Whereas such properties can be conceived as intrinsic properties of particles in classical mechanics, in quantum physics, there is a holistic property or structure that relates all matter and that fixes its temporal development.

Hylomorphism claims that structure is a basic ontological and explanatory principle; it accounts for what things are and what they can do. My goal is to articulate a metaphysic of hylomorphic structure different from those currently on offer. It is based on a substance-attribute ontology that takes properties to be powers and tropes. Hylomorphic structures emerge, on this account, as powers to configure the materials that compose individuals.

Since early modernity, it has often been assumed that miracles are incompatible with the existence of the natural laws utilized in the sciences. This paper argues that this assumption is largely an artifact of empiricist accounts of laws that should be rejected for reasons internal to philosophy of science, and that no such incompatibility arises on the most important alternative interpretations, which treat laws as expressions of forces, dispositions, or causal powers.

Functionalist theories have been proposed for just about everything: mental states, dispositions, moral properties, truth, causation, and much else. The time has come for a functionalist theory of nothing. Or, more accurately, a role functionalist theory of those absences that are causes and effects.

Ordinary Language Philosophy has largely fallen out of favour, and with it the belief in the primary importance of analyses of ordinary language for philosophical purposes. Still, in their various endeavours, philosophers not only from analytic but also from other backgrounds refer to the use and meaning of terms of interest in ordinary parlance. In doing so, they most commonly appeal to their own linguistic intuitions. Often, the appeal to individual intuitions is supplemented by reference to dictionaries. In recent times, (...) Internet search engine queries for expressions of interest have become quite popular. Apparently, philosophers attempt to surpass the limits of their own linguistic intuitions by appealing to experts or to factual uses of language. I argue that this attempt is commendable but that its execution is wanting. Instead of appealing to dictionaries or Internet queries, philosophers should employ computer-based linguistic corpora in order to confirm or falsify hypotheses about the factual use of language. This approach also has some advantages over methods employed by experimental philosophers. If the importance of ordinary language is stressed, the use of linguistic corpora is hardly avoidable.

Powers are popularly assumed to be distinct from, and dependent upon, inert qualities, mainly because it is believed that qualities have their nature independently of other properties while powers have their nature in virtue of a relation to distinct manifestation property. George Molnar and Alexander Bird, on the other hand, characterize powers as intrinsic and relational. The difficulties of reconciling the characteristics of being intrinsic and at the same time essentially related are illustrated in this paper and it is argued (...) that the reasons for thinking of powers as essentially relational are based on misguided epistemological consideration. Finally, I present a way of thinking of fundamental properties as primitive natures that we can only understand in virtue of what they do but which we should not think of as being ontologically constituted by these doings. According to this view, properties are both qualities and powers. (shrink)

The paper aims to elucidate in better detail than before the dispute about whether or not dispositional monism—the view that all basic properties are pure powers—entails a vicious infinite regress. Particular focus is on Alexander Bird's and George Molnar's attempts to show that the arguments professing to demonstrate a vicious regress are inconclusive because they presuppose what they aim to prove, notably that powers are for their nature dependent on something else. I argue that Bird and Molnar are mistaken. It (...) is true that dispositional monism is popularly assumed to characterize powers as dependent entities, but this is not what the arguments aim to prove. They merely aim to demonstrate that it would be absurd to assume that all properties are dependent in this way. Finally, it is argued that there is an unresolved tension in Bird's and Molnar's accounts of powers. They characterize them as being for their nature dependent on the manifestations that they are for, and yet ontologically independent of those same manifestations. Until that tension is resolved, their accounts are not equipped to remove the threat of vicious regress. (shrink)

This thesis concerns the relation between the fundamental properties and the powers they confer. The views considered are introduced in terms of their acceptance or rejection of the quiddistic thesis. Essentially the quiddistic thesis claims that properties confer the powers they do neither necessarily nor sufficiently. Quidditism is the view that accepts the quiddistic thesis. The other two views to be considered, the pure powers view and the grounded view reject the quiddistic thesis. The pure powers view supports its denial (...) of the quiddistic thesis with the claim that properties consist in conferring the powers they do; the possession of a property just is the possession of a power. The grounded view, the positive view of this thesis, rejects the idea that properties are constituted by conferring the causal powers they do. Rather on the grounded view, it is the natures of the fundamental properties that metaphysically explain why they confer the powers they do. (shrink)

Reviews work on moral judgment motivational internalism from the last two decades.

The paper argues in favour of a causal-functional theory of all properties including the physical ones and a conception of properties as tropes or modes in the sense of particular ways that objects are. It shows how these premises open up a version of functionalism according to which the properties on which the special sciences focus are identical with configurations of physical properties and thereby causally efficacious without there being any threat of eliminativism.

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

John Heil’s From an Ontological Point of View (Heil 2003) is a tremendous philosophical work. The neo-Lockean ontology the reader finds within its 267 pages is a sensible and refreshing alternative to the neo-Humean ontologies which presently occupy the vast majority of the metaphysical literature. What Heil offers is a much needed change in perspective. Nor are the strengths of the book limited to Heil’s willingness to approach central metaphysical problems in largely untried and unpopular way; the book is very (...) clear in its presentation, accessible to wide readership, and tightly argued throughout. Heil’s efforts in this book are to be applauded, and the result is one that warrants serious consideration by all those interested in serious metaphysics. But the interest should not end there: the lessons of Heil’s book are ones that almost all philosophers ought to take seriously. Despite the criticism that follows, my overall position should not be taken as anything short of a whole-hearted endorsement of Heil’s book. Nonetheless, when philosophy is one’s trade, there is always going to be something to disagree about, however much one is amenable to a view. (shrink)

Laws of nature seem to take two forms. Fundamental physics discovers laws that hold without exception, ‘strict laws’, as they are sometimes called; even if some laws of fundamental physics are irreducibly probabilistic, the probabilistic relation is thought not to waver. In the nonfundamental, or special, sciences, matters differ. Laws of such sciences as psychology and economics hold only ceteris paribus – that is, when other things are equal. Sometimes events accord with these ceteris paribus laws (c.p. laws, hereafter), but (...) sometimes the laws are not manifest, as if they have somehow been placed in abeyance: the regular relation indicative of natural law can fail in circumstances where an analogous outcome would effectively refute the assertion of strict law. Many authors have questioned the supposed distinction between strict laws and c.p. laws. The brief against it comprises various considerations: from the complaint that c.p. clauses are void of meaning to the claim that, although understood well enough, they should appear in all law-statements. These two concerns, among others, are addressed in due course, but first, I venture a positive proposal. I contend that there is an important contrast between strict laws and c.p. laws, one that rests on an independent distinction between combinatorial and noncombinatorial nomic principles.2 Instantiations of certain properties, e.g., mass and charge, nomically produce individual forces, or more generally, causal influences,3 in accordance with noncombinatorial..

In our philosophical tradition and our wider culture, we tend to think of persons as agents. This agential conception is flattering, but in this paper I will argue that it conceals a more complex truth about what persons are. In 1. I set the issues in context. In 2. I critically explore four features commonly presented as fundamental to personhood in versions of the agential conception: action, capability, choice and independence. In 3. I argue that each of these agential features (...) presupposes a non-agential feature: agency presupposes patiency, capability presupposes incapability, choice presupposes necessity and independence presupposes dependency. In 4. I argue that such non-agential features, as well as being implicit within the agential conception, are as apt to be constitutive of personhood as agential features, and in 5. I conclude.

The paper first argues that if one takes current fundamental physics seriously, one gets to a metaphysics of events and relations in contrast to substances and intrinsic properties. Against that background, the paper discusses Heil’s theory of properties being both categorical and dispositional and his rejection of levels of being. I contrast these views with a Humean metaphysics. My concluding claim is that Heil’s account of properties opens up the perspective of a conservative reductionism, which avoids the common reservations against (...) reductionism. (shrink)

Brian Ellis advances a robust species of realism he calls Physical Realism. Physical Realism includes an ontology comprising three kinds of universal and three kinds of particular: a six‐category ontology. After comparing Physical Realism to a modest two‐category ontology inspired by Locke, I mention two apparent difficulties a proponent of a six‐category ontology might address.1.

This paper develops two ideas with respect to dispositional properties: (1) Adapting a suggestion of Sungho Choi, it appears the conceptual distinction between dispositional and categorical properties can be drawn in terms of susceptibility to finks and antidotes. Dispositional, but not categorical properties, are not susceptible to intrinsic finks, nor are they remediable by intrinsic antidotes. (2) If correct, this suggests the possibility that some dispositions—those which lack any causal basis—may be insusceptible to any fink or antidote. Since finks and (...) antidotes are a major obstacle to a conditional analysis of dispositions, these dispositions that are unfinkable may be successfully analysed by the conditional analysis of dispositions. This result is of importance for those who think that the fundamental properties might be dispositions which lack any distinct causal basis, because it suggests that these properties, if they exist, can be analysed by simple conditionals and that they will not be subject to ceteris paribus laws. (shrink)

I argue that any broadly dispositional analysis of probability will either fail to give an adequate explication of probability, or else will fail to provide an explication that can be gainfully employed elsewhere (for instance, in empirical science or in the regulation of credence). The diversity and number of arguments suggests that there is little prospect of any successful analysis along these lines.

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)

The paper argues for four claims: (1) The problem of mental causation and the argument for its solution in terms of the identity of mental with physical causes are independent of the theory of causation one favours. (2) If one considers our experience of agency as described by folk psychology to be veridical, one is committed to an anti-Humean metaphysics of causation in terms of powers that establish necessary connections. The same goes for functional properties in general. (3) A metaphysics (...) of causation in terms of powers is compatible with physics. (4) If combined with the argument for mental causes being identical with physical causes, that metaphysics leads to a conservative reductionism. (shrink)

The idea that causation involves the production of changes due to the exertion of influence of something on something else—the core idea of causal realism—used to be the default view. Today this idea is at the heart of (i) transmission/causal process accounts, (ii) mechanistic accounts, and (iii) powers-based accounts. However, as I have previously argued (Ingthorsson 2021) the above-mentioned approaches are based—to varying degree—on the very problematic assumption that causal influence is essentially unidirectional; that it passes from whatever is the (...) cause to the effect. As first pointed out be Mario Bunge (1959), the idea that causal influence is unidirectional is incompatible with what is today considered a scientific fact, notably that all interactions are perfectly reciprocal; whenever any object exerts an influence on any other object, the latter simultaneously exerts the same kind of influence, of the same magnitude, on the former. Drawing on Bunge’s result, I have developed a fourth approach to efficient causation that accepts the reciprocity of interactions (Ingthorsson 2002 & 2021). According to this view a cause is not the action of something on something else that receives the influence, but the reciprocal action between powerful particulars which results in a modification of both sides, producing a new state of affairs. In this paper, I present the core ideas of the four different approaches to causal efficacy, what I think is problematic with the first three and finally attempt to compare how well the four approaches fare in explaining two often discussed types of causal interactions: (i) collisions between billiard balls, and (ii) how water dissolves salt. I argue that only reciprocal actions between powerful particulars can plausibly claim to fully account for these phenomena, in a manner compatible with the theories and findings of the natural sciences.

As we understand them, dispositions are relatively uncontroversial 'predicatory' properties had by objects disposed in certain ways. By contrast, powers are hypothetical 'ontic' properties posited in order to explain dispositional behaviour. Chapter 1 outlines this distinction in more detail. Chapter 2 offers a summary of the issues surrounding analysis of dispositions and various strategies in contemporary literature to address them, including one of our own. Chapter 3 describes some of the important questions facing the metaphysics of powers including why they're (...) worth positing, and how they might metaphysically explain laws of nature and modality.

The paper discusses Hilbert mathematics, a kind of Pythagorean mathematics, to which the physical world is a particular case. The parameter of the “distance between finiteness and infinity” is crucial. Any nonzero finite value of it features the particular case in the frameworks of Hilbert mathematics where the physical world appears “ex nihilo” by virtue of an only mathematical necessity or quantum information conservation physically. One does not need the mythical Big Bang which serves to concentrate all the violations of (...) energy conservation in a “safe”, maximally remote point in the alleged “beginning of the universe”. On the contrary, an omnipresent and omnitemporal medium obeying quantum information conservation rather than energy conservation permanently generates action and thus the physical world. The utilization of that creation “ex nihilo” is accessible to humankind, at least theoretically, as long as one observes the physical laws, which admit it in their new and wider generalization. One can oppose Hilbert mathematics to Gödel mathematics, which can be identified as all the standard mathematics until now featureable by the Gödel dichotomy of arithmetic to set theory: and then, “dialectic”, “intuitionistic”, and “Gödelian” mathematics within the former, according to a negative, positive, or zero value of the distance between finiteness and infinity. A mapping of Hilbert mathematics into pseudo-Riemannian space corresponds, therefore allowing for gravitation to be interpreted purely mathematically and ontologically in a Pythagorean sense. Information and quantum information can be involved in the foundations of mathematics and linked to the axiom of choice or alternatively, to the field of all rational numbers, from which the pair of both dual and anti-isometric Peano arithmetics featuring Hilbert arithmetic are immediately inferable. Noether’s theorems (1918) imply quantum information conservation as the maximally possible generalization of the pair of the conservation of a physical quantity and the corresponding Lie group of its conjugate. Hilbert mathematics can be interpreted from their viewpoint also after an algebraic generalization of them. Following the ideas of Noether’s theorem (1918), locality and nonlocality can be realized both physically and mathematically. The “light phase of the universe” can be linked to the gap of mathematics and physics in the Cartesian organization of cognition in Modernity and then opposed to its “dark phase”, in which physics and mathematics are merged. All physical quantities can be deduced from only mathematical premises by the mediation of the most fundamental physical constants such as the speed of light in a vacuum, the Planck and gravitational constants once they have been interpreted by the relation of locality and nonlocality.

This paper presents the view that tropes can change, and so are not individuated by their determinate qualitative characters. On the view I have in mind, a trope is at any given time fully determinate, but can change qualitatively within the bounds set by a determinable essence. A charge trope, for example, must at any time have some exact intensity, but can survive changes in intensity. My argument, roughly, is this: Objects can change, and tropes are the parts of objects (...) that change (in a special sense of ‘part’), so tropes can change too. After some preliminaries, I present the argument carefully and discuss the operant notions. I then discuss each premise in turn. I respond to the charge that the view isn't realist, and to objections based on identity‐conditions for tropes. I describe both substratum‐ and bundle‐theoretic versions of the view, and finally, show what the view buys us. (shrink)

Dispositionalism is the theory of modality that grounds all modal truths in powers: all metaphysically possible and necessary truths are to be explained by pointing to some actual power, or absence thereof. One of the main reasons to endorse dispositionalism is that it promises to deliver an especially desirable epistemology of modality. However, so far this issue has not be fully investigated with the care it is due. The aim of this paper is to fill this gap. We will cast (...) some doubts on whether the dispositionalist really is in a better position to explain our modal knowledge. In fact, we argue that there is a tension between some core tenets of a powers metaphysics and the very features that make dispositionalism the ideal backdrop for a desirable epistemology of modality. We conclude that this leaves dispositionalists who want to deliver the promised epistemology with a hard, currently unfulfilled, task. (shrink)

Metaphysical grounding is often presented as a relation of directed dependence analogous to causation. The relationship between causation, properties, and laws of nature is hotly debated. I ask: what is the relationship between grounding, properties, and laws of metaphysics? I begin by considering the grounding analogue of Humean quidditism. Finding it implausible, I turn to the primitive-laws account of grounding, recently defended by Jonathan Schaffer and others. I argue this view is also unsatisfactory. I then present several possible dispositionalist-like accounts (...) and characterize the notion of a power to ground. I argue for three important conclusions: (i) each property essentially confers grounding powers; (ii) non-fundamental properties can be defined structurally in a particular sense, elucidating the claim that they are ‘nothing over and above’ the fundamental; and (iii) fundamental properties play a central role in grounding the grounding facts. Finally, it is significant that, combined with a causal powers-account of causal explanation, the door is open to a unified account of the metaphysics of causation and grounding: both flow from the natures of fundamental properties.

Primary to both ontology and epistemology is the attributional union that properties and relations have with their subjects. Yet, the tradition’s understanding of attribution has been assessed as shallow, and its contemporary analysis deemed locked in a non-progressing stalemate. Central here is the historically dominant __in___herence_/_constituent_ construal of attribution, what, I argue, has remained obscure and unattended as to its background assumptions and their implications. On the analysis offered herein, I make precise and detail errors of the defining assumptions of (...) inherence theory and the _two-tiered nature_ it requires of attribution. Brought into relief will be the four elements involved in every attributional union, and what are the errors in a sequence of collapsing identities among them that define inherence theory. Along the way, clarification and warrant is provided for the alternative theses and their implications defining an __ad___herence_ theory of attribution, key features synopsized in the last section.

An important task for metaphysicians and philosophers of science is to account for laws of nature – in particular, how they distinguish themselves from ‘mere’ regularities, and the modal force they are endowed with, ‘natural necessity’. Dispositional essentialism about laws is roughly the view that laws distinguish themselves by being grounded in the essences of natural entities. This paper does not primarily concern how essentialism compares to its main rivals – Humeanism and Armstrongeanism. Rather, it distinguishes and comparatively assesses various (...) brands of essentialism – which mainly differ as to where exactly they take laws to find their essentialist sources, and what they take to be the targets of laws, namely what they apply to. Yet, this internal comparison is not unrelated to the more general debate about laws: the main criteria with which I compare these essentialist views concern how they can deal with some of the main objections faced by essentialism in general, and how they can keep what is arguably the main intuitive advantage of essentialism over its rivals. Thus, the paper also concerns the relative position of essentialism in the larger debate about laws – ultimately bringing support to it. (shrink)

One of the most pressing challenges that occupy the Russellian panpsychist’s agenda is to come up with a way to reconcile the traditional argument from categorical properties (Seager, 2006; Alter & Nagasawa, 2015) with H. H. Mørch’s dispositionalism-friendly argument from the experience of causation (2014, 2018, 2020) — on the way to a unitary, all-encompassing case for the view. In this regard, Mørch claims that, via the commitment to the Identity theory of properties, one can consistently hold both panpsychist arguments (...) without contradiction (2020: 281) — I shall refer to such proposal as Reconciliation. In my paper, I shall argue that this is not the case. To this extent, I will first consider H. Taylor’s argument that the Identity theorists have the exact same resources as the dispositionalists (as, after careful enquiry, their views on the metaphysics of properties turn out to coincide (2018: 1438)), and thus contend that Reconciliation fails to obtain. Then, I will suggest that one can avoid the problem and reconcile the arguments by adopting a different version of the powerful qualities view, namely the Compound view — and thus advance a reformulated version of the claim, i.e. Reconciliation*. Finally, even though pursuing my proposed solution might expose Russellian panpsychism to the risk of epiphenomenalism, I shall conclude that such specific form of epiphenomenalism is a rather benign one, and thus that, via Reconciliation*, the constitution of a unitary case for panpsychism as a positive proposal (and not as a mere alternative to dualism and physicalism) can be achieved.

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)

Power enthusiasts are engaged in two projects: developing a decent metaphysical account of powers, and applying that account in order to make progress on various other philosophical issues, ranging from narrowly related topics such as causality to further removed ones such as free will, reasoning, or perception. I argue that an intermediate step may be taken, one that explores ‘varieties of power’ while still staying within the realm of, of ‘pure’ powers metaphysics. Taking this intermediate step provides a much more (...) interesting basis for those involved in project, ‘applied’ powers metaphysics. I articulate four such varieties of power by exploring various dimensions in which the explanatory profile of a power can be extended. I then briefly survey how these relate to various further metaphysical issues. (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.

One controversial position in the debate over dispositional and categorical properties maintains that our concepts of these properties are the result of partially considering unitary properties that are both dispositional and categorical. As one of its defenders (Heil 2005, p. 351) admits, this position is typically met with “incredulous stares”. In this paper, I examine whether such a reaction is warranted. This thesis about properties is an instance of what I call “the Partial Consideration Strategy”—i.e., the strategy of claiming that (...) what were formerly thought of as distinct entities are actually a unified entity, partially considered. By evaluating its use in other debates, I uncover a multi-layered _prima facie_ case against the use of the Partial Consideration Strategy in the dispositional/categorical properties debate. In closing, I describe how the Partial Consideration Strategy can be reworked in a way that would allow it to sidestep this _prima facie_ case. (shrink)

Metaphysical orthodoxy holds that a privileged minority of properties carve reality at its joints. These are the so-called fundamental properties. This thesis concerns the contemporary philosophical debate about the nature of fundamental properties. In particular, it aims to answer two questions: What is the most adequate conception of fundamental properties? What is the “big picture” world-view that emerges by adopting such a conception? I argue that a satisfactory answer to both questions requires us to embrace a novel conception of powerful (...) qualities, according to which properties are at once dispositional and qualitative. By adopting the proposed conception of powerful qualities, an original theory of fundamental properties comes to light. I call it Dual-Aspect Account. In this thesis, I defend the Dual-Aspect Account and its superiority with respect to rival views of fundamental properties. I illustrate this claim by examining Dispositionalism, the view defended among others by Alexander Bird and Stephen Mumford, Categoricalism, which has been advocated notably by David Lewis and David Armstrong, and the Identity Theory of powerful qualities, primarily championed by C. B. Martin and John Heil. The latter is the standard conception of powerful qualities. However, in the literature, the Identity Theory faces the charge of contradiction. A preliminary task is therefore to show that a conception of powerful qualities is coherent. To accomplish this aim, I introduce the notion of an aspect of a property. On this interpretation, powerful qualities can be thought of as having dispositional and qualitative aspects. I show that such a conception allows us to disambiguate the claim that a property’s dispositionality is identical with its qualitativity, and evade the charge of contradiction. Aspects bring us other theoretical benefits. I illustrate this claim by showing how the Dual-Aspect Account offers us a promising theory of resemblance. I then compare its merits with David Armstrong’s theory of partial identity. The conclusion of this thesis is that the Dual-Aspect Account is better suited to capturing the world as we find it in everyday life and scientific investigation as compared to the theoretical positions examined.

ABSTRACTThe paper takes up a conception of substances according to which substances are simple property bearers, properties being modes, particular qualitative ways individual substances are. What a substance does or would do is determined by its qualities. Efficient causation is to be understood as the manifesting of powers possessed by substances owing to their qualitative natures. Although complexes, entities with substantial parts, are not substances, they would be no less real, no less participants in the causal fray. What the substances (...) and properties are is an empirical matter, however, to be settled, if at all, by physics. For all we know, the substances might be particles, or fields, or the universe as a whole. Efficient causation appears to require pluralism: distinct interacting substances. In a non-pluralistic universe, causal truths would be relegated to the manifest image: true still, but made true by non-causal features of the universe perhaps revealed by the scientific image. There remains the final reflection, how shallow, puny, and imperfect are efforts to sound the depths in the nature of things. In philosophical discussion, the merest hint of dogmatic certainty as to finality of statement is an exhibition of folly. : x). (shrink)

In the pure powers ontology (PPO), basic physical properties have wholly dispositional essences. PPO has clear advantages over categoricalist ontologies, which suffer from familiar epistemological and metaphysical problems. However, opponents argue that because it contains no qualitative properties, PPO lacks the resources to individuate powers, and generates a regress. The challenge for those who take such arguments seriously is to introduce qualitative properties without reintroducing the problems that PPO was meant to solve. In this paper, I distinguish the core claim (...) of PPO: (i) basic physical properties have dispositional essences, from a hitherto unnoticed assumption: (ii) the dispositional essences of basic physical properties exclusively involve type-causal relations to other basic physical properties. I reject (ii), making room for a structuralist ontology in which all basic physical properties are pure powers, individuated by their places in a causal structure that includes not only other powers, but also physically realized qualitative properties such as shapes, patterns and structures. Such qualities individuate pure powers in the way that non-mental input and output properties individuate realized mental properties in functionalist theories of mind, except that here it is basic physical powers that are individuated by relations to realized non-powers. I distinguish one Platonic and two Aristotelian version of this theory, and argue that the Aristotelian versions require that grounding is not always a relative fundamentality relation, because the powers ground the qualities that individuate them. By considering ontic structural realism, I argue that symmetric grounding is the best way to make sense of relational individuation in structuralist ontologies, and is therefore no additional commitment of the one proposed here.

In this paper, I address the grounding problem for contemporary Russellian panpsychism, or the question of how consciousness as an intrinsic nature is connected to dispositions or powers of objects. I claim that Russellian panpsychists cannot offer an adequate solution to the grounding problem and that they should reject the claim that consciousness, as an intrinsic nature, grounds the powers of objects. Instead, I argue that they should favour the identity theory of powers, where categorical and dispositional properties are identified. (...) I maintain that the identity theory serves as a better ontological basis for panpsychism since it avoids the grounding problem. Apart from that, I also argue that identity theory panpsychism is a position more parsimonious than Russellian panpsychism since it introduces fewer entities while successfully avoiding the grounding problem. Based on these considerations, I conclude that identity theory panpsychism is an option worth considering. (shrink)

In some recent work on omissions, it has been argued that the causal theory of action cannot account for how agency is exercised in intentionally omitting to act in the same way it explains how agency is exercised in intentional action. Thus, causalism appears to provide us with an incomplete picture of intentional agency. I argue that causalists should distinguish causalism as a general theory of intentional agency from causalism as a theory of intentional action. Specifically, I argue that, while (...) intentional actions may best be understood as the causal products or outcomes of causings, we should identify exercises of intentional agency with causal processes. With a causalist account of intentional agency sketched, I respond to the challenge to causalism from omissions. I argue that when an agent intentionally omits there is a causal process that has a zero-sum outcome. But the causal process is sufficient to make it true that the agent exercises intentional agency in intentionally omitting. (shrink)

This paper argues against the realization principle, which reifies the realization relation between lower-level and higher-level properties. It begins with a review of some principles of naturalistic metaphysics. Then it criticizes some likely reasons for embracing the realization principle, and finally it argues against the principle directly. The most likely reasons for embracing the principle depend on the dubious assumption that special science theories cannot be true unless special science predicates designate properties. The principle itself turns out to be false (...) because the realization relation fails the naturalistic test for reality: it makes no causal difference to the world.Footnote11This paper resulted from work done at John Heil's 2006 Mind and Metaphysics NEH Summer Seminar at Washington University in St. Louis. An early version of it was presented in a special symposium on realization at the 2007 meeting of the Southern Society for Philosophy and Psychology. I owe thanks to all the participants in both events for helpful discussions, and I owe particular thanks to Ken Aizawa, Torin Alter, Jason Ford, Carl Gillett, John Heil, Nicholas Helms, Pete Mandik, John Post, Gene Witmer, Michelle Wrenn, Tad Zawidzki, and two anonymous referees for the AJP.

The question of how properties are individuated is extremely important. Consider the following proposals. To be in pain is to be in a certain neurological state. To be red is to appear red to normal observers in standard conditions. To be obligatory is to maximize the good. Each makes a claim of property identity. Each is a substantive metaphysical thesis of wide interest. None can be studied with due scrutiny in the absence of a general account of property identity. Here, (...) I will survey existing accounts and suggest a new account in terms of grounding that has some advantages over the other candidates. (shrink)

In considering the nature of properties four controversial decisions must be made. (1) Are properties universals or tropes? (2) Are properties attributes of particulars, or are particulars just bundles of properties? (3) Are properties categorical (qualitative) in nature, or are they powers? (4) If a property attaches to a particular, is this predication contingent, or is it necessary? These choices seem to be in a great degree independent of each other. The author indicates his own choices.

As far as classical physics is concerned, it is possible to trace causal relations between physical objects back to intrinsic properties of these objects. On this view, causal relations turn out to be internal instead of external relations, supervening on intrinsic properties of the relata. However, one can raise doubts about this view already in Newtonian mechanics. The decisive blow to this view comes from quantum physics, with Bell’s theorem proving that no dynamics based on local, intrinsic properties of quantum (...) objects can yield the empirical predictions of quantum mechanics. Nonetheless, quantum entanglement by no means implies that we have to abandon an ontology of objects in favour of an ontology of structures. Any of the known proposals for a quantum ontology of matter in space-time is committed to objects. However, on any of these proposals, what determines the dynamics of these objects are not local, intrinsic properties, but a global or holistic property instantiated by all the objects together – that is, a structure that takes all the objects in the universe as its relata. The view set out in this paper thus amounts to combining ontic structural realism with an ontology of objects that can be conceived as substances. This suggestion is illustrated by drawing on the ontology of quantum physics worked out by Bohm and Bell. (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.
