According to the grounding theory of powers, fundamental physical properties should be thought of as qualities that ground dispositions. Although this view has recently been defended by many different philosophers, there is no consensus for how the view should be developed within a broader metaphysics of properties. Recently, Tugby has argued that the view should be developed in the context of a Platonic theory of properties, where properties are abstract universals. I will argue that the view should not be developed (...) within such a framework. Either the view should be developed with an ontology of Aristotelian properties, or it should be developed in a Nominalist framework that contains no properties at all. (shrink)

In this paper I argue that much of the confusion and mystery surrounding the concept of "self" can be traced to a failure to appreciate the distinction between the self as a collection of diverse neural components that provide us with our beliefs, memories, desires, personality, emotions, etc (the epistemological self) and the self that is best conceived as subjective, unified awareness, a point of view in the first person (ontological self). While the former can, and indeed has, been extensively (...) studied by researchers of various disciplines in the human sciences, the latter most often has been ignored -- treated more as a place holder attached to a particular predicate of interest (e.g., concept, reference, deception, esteem, image, regulation, etc). These two aspects of the self, I contend, are not reducible -- one being an object (the epistemological self) and the other a subject (the ontological self). Until we appreciate the difficulties of applying scientific methods and analysis to what cannot be reduced to an object of inquiry without stripping it of its essential aspect (its status as subject), progress on the "self", taken as a pluralistic construct, will continue to address only one part of the problems we face in understanding this most fundamental aspect of human experience.

Some philosophers working on the metaphysics of agency argue that if agency is understood in terms of settling the truth of some matters, then the power required for the exercise of intentional agency is an irreducible two-way power to either make it true that p or not-p. In this paper, the focus is on two-way powers in decision-making. Two problems are raised for theories of decision-making that are ontologically committed to irreducible two-way powers. First, recent accounts lack an adequate framework (...) for explaining decisions by the reasons of agents. Second, accepting ontologically irreducible two-way powers into one’s metaphysic of agency implies an ontological commitment to substance dualism. An ontologically less-costly alternative to irreducible two-way powers is offered. It is argued that a reductive account of two-way powers in terms of what George Molnar called “derivative powers” should be accepted. The reductive account can provide us with the truthmakers for talk about two-way powers. Moreover, the reductive account does not share the liabilities of accepting irreducible two-way powers.

How should we account for the extraordinary regularity in the world? Humeans and Non-Humeans sharply disagree. According to Non-Humeans, the world behaves in an extraordinarily regular way because of certain necessary connections in nature. However, Humeans have thought that Non-Humean views are metaphysically objectionable. In particular, there are two general metaphysical principles that Humeans have found attractive that are incompatible with all existing versions of Non-Humeanism. My goal in this paper is to develop a novel version of Non-Humeanism that is (...) consistent with (and even entails) both of these general metaphysical principles. By endorsing such a view, one can have the explanatory benefits of Non-Humeanism while at the same time avoiding two of the major metaphysical objections towards Non-Humeanism. (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)

Mental causation, idea that it is us – via our minds – who cause bodily actions is as commonsensical as it is indispensable for our understanding of ourselves as rational agents. Somewhat less uncontroversial, but nonetheless widespread (at least among ordinary people) is the idea that the mind is non-physical, following the intuition that what is physical can neither act nor think nor judge morally. Taken together, and cast into a metaphysical thesis, the two intuitions yield interactive dualism: the view (...) that human persons and their minds are non-physical but can nonetheless interact with their bodies, most notably through their brains. This thesis has two main objectives: first, to defend interactive dualism against objections, and second, to show how it can blend in with a physical world in which laws of nature hold. The first part (chapter 1) consists in a brief motivation of interactive dualism as opposed to non-interactive dualism. I argue that non-interactive, epiphenomenalist dualism sacrifices so many crucial aspects of our human existence that interactive dualism is highly to be preferred to it, barring even stronger counterarguments against the latter. It is those putative counterarguments I address in parts II and III. Part II takes on the philosophical objections from the causal closure of the physical and from causal heterogeneity. The former takes the success of physics and physiology as basis for the doctrine of the causal closure of the physical (CCP). I argue against this that there is not only no convincing argument for CCP, but also that any science-based belief in CCP cannot be epistemically justified. As regards the causal heterogeneity objection, it is ‘weighed and found wanting’, because it relies on unwarranted assumptions about causation. In part III, I examine the objection from energy conservation. It roughly says that if interactive dualism were true, then energy would not be conserved, which physics taught us cannot be the case. My reply is that the underlying conception of energy (and momentum) conservation is wrong-headed and not the one that actual physicists use. Instead of being categorical and global, conservation laws are conditional and local, thereby making natural room for mental interaction. Some dualists, however, have sought to make interactive dualism conservation-friendly, notably by invoking quantum physics; I show that these attempts are unnecessary and create more problems than they solve. Finally, in chapter 9, I turn the tables on non-interactionists by investigating current neurophysiological literature on volitional actions, which, though not addressing the question directly, still encourages the interactive dualist picture more than a non-interactionist one. Part IV is about the interplay between interactive dualism and the laws of nature. The ultimate goal is, if possible, to come up with a theory of the laws of nature that explains the lawlike behavior of nature and at the same time makes room for interaction. I begin by pointing out that the laws of nature are or at least should be what physicalists worry about (chapter 10). I then proceed with a historical survey on the development of the notion of laws of nature (chapter 11) that sheds light on its theistic origin. This is followed by an inquiry into the question how a law of nature could possibly be broken (chapter 12) and a survey of the extant metaphysical theories of the laws of nature with special regard to their receptivity to interaction (chapter 13). Finally, in chapter 14 I develop a theory of the laws of nature both faithful to their divine origin and the possibility of mental interaction: dispositionalist divine decretalism, a synthesis of dispositionalism and Jeffrey Koperski’s divine decretalism.

Understanding consciousness and its place in the natural world is one of the principal targets of contemporary philosophy of mind. Australian philosophers made seminal contributions to this project during the twentieth century which continue to shape the way philosophers and scientists think about the conceptual, metaphysical and empirical aspects of the problem. After some scene setting, I will discuss the main players and their work in the context of broader developments in the philosophy of mind.

Externalists about epistemic justification have long emphasized the connection between truth and justification, with this coupling finding explicit expression in process reliabilism. Process reliabilism, however, faces a number of severe difficulties, leading disenchanted process reliabilists to find a new theoretical home. The conceptual flag under which such epistemologists have preferred to gather is that of dispositions. Just as reliabilism is determined by the frequency of a particular outcome, making it possible to characterize justification in terms of a particular relationship to (...) truth, dispositions are accompanied by concrete, worldly manifestations. By taking true beliefs as the result, not of certain processes but of particular dispositions, these epistemologists have attempted to respond to the numerous obstacles to reliabilism. Yet all this work has proceeded without regard to the wealth of contemporary work on the metaphysics of dispositions, making the new hope premature at best, ill-founded at worst. Combining contemporary dispositional accounts of justification with extant analyses of dispositions reveals that the latter is the case. The structural differences between epistemic justification and dispositions make it clear that not only should process reliabilism be abandoned, but the subsequent appeal to dispositions along with it.

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)

According to dispositionalism about modality, a proposition <p> is possible just in case something has, or some things have, a power or disposition for its truth; and <p> is necessary just in case nothing has a power for its falsity. But are there enough powers to go around? In Yates (2015) I argued that in the case of mathematical truths such as <2+2=4>, nothing has the power to bring about their falsity or their truth, which means they come out both (...) necessary and not possible. Combining this with axiom (T), it is easy to derive a contradiction. I suggested that dispositionalists ought to retreat a little and say that <p> is possible just in case either p, or there is a power to bring it about that p, grounding the possibility of mathematical propositions in their truth rather than in powers. Vetter’s (2015) has the resources to provide a response to my argument, and in her (2018) she explicitly addresses it by arguing for a plenitude of powers, based on the idea that dispositions come in degrees, with necessary properties a limiting case of dispositionality. On this view there is a power for <2+2=4>, without there being a power to bring about its truth. In this paper I argue that Vetter’s case for plenitude does not work. However, I suggest, if we are prepared to accept metaphysical causation, a case can be made that there is indeed a power for <2+2=4>. (shrink)

Although contemporary metaphysics has recently undergone a neo-Aristotelian revival wherein dispositions, or capacities are now commonplace in empirically grounded ontologies, being routinely utilised in theories of causality and modality, a central Aristotelian concept has yet to be given serious attention – the doctrine of hylomorphism. The reason for this is clear: while the Aristotelian ontological distinction between actuality and potentiality has proven to be a fruitful conceptual framework with which to model the operation of the natural world, the distinction between (...) form and matter has yet to similarly earn its keep. In this chapter, I offer a first step toward showing that the hylomorphic framework is up to that task. To do so, I return to the birthplace of that doctrine - the biological realm. Utilising recent advances in developmental biology, I argue that the hylomorphic framework is an empirically adequate and conceptually rich explanatory schema with which to model the nature of organisms.

Although they are continually compositionally reconstituted and reconfigured, organisms nonetheless persist as ontologically unified beings over time – but in virtue of what? A common answer is: in virtue of their continued possession of the capacity for morphological invariance which persists through, and in spite of, their mereological alteration. While we acknowledge that organisms‟ capacity for the “stability of form” – homeostasis - is an important aspect of their diachronic unity, we argue that this capacity is derived from, and grounded (...) in a more primitive one – namely, the homeodynamic capacity for the “specified variation of form”. In introducing a novel type of causal power – a „structural power‟ – we claim that it is the persistence of their dynamic potential to produce a specified series of structurally adaptive morphologies which grounds organisms‟ privileged status as metaphysically “one over many” over time.

The Perennial Philosophy centres around what is said to be a recurring mystical insight: that our inherent nature is actually pure, unconditioned consciousness, identical to the ground of all being. Perennial Idealism, the name I give to a metaphysical system I have been building, extrapolates from the Perennial Philosophy to explain how the world could be configured if it were in fact true. Among the most serious challenges faced is that of articulating and defending the very notion that our world (...) is grounded in universal consciousness. This chapter further develops a line of reply to what I think are four major objections to the idea that universal consciousness grounds all being. I call these the Thales Objection, the Problem of the One and the Many, the Self-defeating Objection, and the Power Challenge. (shrink)

I take it that the following is a desideratum of our theories in the philosophy of mind. A theory in the philosophy of mind should help us better understand ourselves as agents and aid in our theorizing about the nature of action and agency. In this paper I discuss a strategy adopted by some defenders of nonreductive physicalism in response to the problem of causal exclusion. The strategy, which I refer to as “intralevelism,” relies on treating mental causation as intra (...) level mental to mental causation, rather than as involving any inter level mental to physical causation. I raise problems for intralevelist theories of mental causation that stem from action-theoretic considerations. Specifically, I focus on the failure of intralevelist proposals to account for the problem of basic causal deviance in the etiology of action. To the extent that intralevelism fails to make room for basic causal deviance, the strategy fails to satisfy the aforementioned desideratum, viz ., that our theories in the philosophy of mind should be of use in theorizing about action and agency. The upshot is that intralevelism is a less promising strategy for nonreductive physicalists than it appears at first glance. (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.

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 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)

Part of our ordinary conception of our freedom is the idea that commonly when we act—and often even when we don’t act—it is up to us whether we do this or that. This paper examines efforts to spell out what must be the case for this idea to be correct. Several claims regarding the basic metaphysics of agential powers are considered; they are found not to shed light on the issue. Thinking about agents’ psychological capacities provides some illumination, though the (...) idea of freedom remains puzzling. (shrink)

Several theories of causation reject causation of or by absences. They thereby clash with much of what we think and say about what causes what. This paper examines a way in which one kind of theory, causal dispositionalism, can be modified so as to accept absence causation, while still retaining a fundamental commitment of dispositionalism. The proposal adopts parts of a strategy described by David Lewis. The paper concludes with a brief discussion of the problem of the proliferation of causes.

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.

One recently popular way to characterise strong emergence is to say that emergent entities possess novel causal powers. However, there is little agreement concerning the nature of powers. One controversy involves whether powers are single- or multi-track; that is, whether each power has only one manifestation type, or whether a single power can be directed towards a number of distinct manifestations. Another concerns how powers operate: whether a lone power manifests when triggered by the presence of a suitable stimulus, or (...) whether powers operate mutually such that several powers must ‘work together’ to bring about a particular manifestation. This paper examines how these distinctions—which can be cross-combined to frame four distinct accounts of the nature of powers—bear on the debate between emergentists and reductionists. (shrink)

This short paper explores how issues concerning the metaphysics of powers/dispositions might bear on the view that formative influence in education involves instilling appropriate dispositions.

In his landmark book on philosophical theology, Saving God: Religion After Idolatry, Mark Johnston develops a panentheistic metaphysic of the divine that he contends is compatible with ontological naturalism. On his view, God is the universe, but the ‘is’ is the ‘is’ of constitution, not identity. The universe and God are coinciding objects that share properties but have different essential modal properties and, hence, different persistence conditions. In this paper, I address the problem of accounting for what it is about (...) the organization or structure of the universe that makes it sufficient to constitute the Divine Mind. Specifically, I consider what kind of unity the universe exhibits in virtue of which it constitutes the Divine Mind. I consider how Johnston’s hylomorphic account of the unity of composite objects might be applied to provide a solution and offer an alternative that emends the Johnstonian proposal I present by exploiting a variant of a neo-Aristotelian ontology of causal powers that takes properties to be powerful qualities. On the framework I defend, we can understand the universe as a constellation of powers that displays the sort of unity sufficient to truthfully described it as a Divine Mind. The approach I recommend will, however, ultimately lend itself to a pantheistic metaphysic of the divine rather than Johnston’s preferred panentheism. (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 identifies and critiques a theory of mental causation defended by some proponents of nonredutive physicalism that I call “intralevelism.” Intralevelist theories differ in their details. On all versions, the causal outcome of the manifestation of physical properties is physical and the causal outcome of the manifestation of mental properties is mental. Thus, mental causation on this view is intralevel mental to mental causation. This characterization of mental causation as intralevel is taken to insulate nonreductive physicalism from some objections (...) to nonreductive physicalism, including versions of the exclusion argument. This paper examines some features of three recent versions of intralevelism defended by John Gibbons, Markus Schlosser, and Amie Thomasson. This paper shows that the distinctive problems faced by these three representative versions of intralevelism suggest that the intralevelist strategy does not provide a viable solution to the exclusion problem.

We examine Sophie Gibb’s emergent property-dualist theory of mental causation as double-prevention. Her account builds on a commitment to a version of causal realism based on a powers metaphysic. We consider three objections to her account. We show, by drawing out the implications of the ontological commitments of Gibb’s theory of mental causation, that the first two objections fail. But, we argue, owing to worries about cases where there is no double-preventive role to be played by mental properties, her account, (...) which solely affords mental properties a double-preventive role, is incomplete and vulnerable to a causal exclusion objection. We propose a friendly modification to her theory of mental causation that is consistent with her theory’s ontological commitments. Specifically, we sketch an account on which mental properties have a more pronounced causal-structuring role that is not exhausted by the role Gibb assigns them as double-preventers. The result is a novel emergentist theory of mental causation. (shrink)

In her recent paper, “A Defense of Substance Causation,” Ann Whittle makes a case for substance causation. In this paper, assuming that causation is a generative or productive relation, I argue that Whittle’s argument is not successful. While substances are causally relevant in causal processes owing to outcomes being counterfactually dependent upon their role in such occurrences, the real productive work in causal processes is accomplished by the causal powers of substances.

In a series of papers, Jesper Kallestrup and Duncan Pritchard argue that the thesis that knowledge is a cognitive success because of cognitive ability (robust virtue epistemology) is incompatible with the idea that whether or not an agent’s true belief amounts to knowledge can significantly depend upon factors beyond her cognitive agency (epistemic dependence). In particular, certain purely modal facts seem to preclude knowledge, while the contribution of other agents’ cognitive abilities seems to enable it. Kallestrup and Pritchard’s arguments are (...) targeted against views that hold that all it takes to manifest one’s cognitive agency is to properly exercise one’s belief-forming abilities. I offer an account of the notion of cognitive ability according to which our epistemic resources are not exhausted by abilities to produce true beliefs as outputs, but also include dispositions to stop belief-formation when actual or modal circumstances are not suitable for it (precautionary cognitive abilities). Knowledge, I argue, can be accordingly conceived as a cognitive success that is also due to the latter. The resulting version of robust virtue epistemology helps explain how purely modal facts as well as other agents’ cognitive abilities may have a bearing on the manifestation of one’s cognitive agency, which shows in turn that robust virtue epistemology and epistemic dependence are not incompatible after all.

My primary aim is to defend a nonreductive solution to the problem of action. I argue that when you are performing an overt bodily action, you are playing an irreducible causal role in bringing about, sustaining, and controlling the movements of your body, a causal role best understood as an instance of agent causation. Thus, the solution that I defend employs a notion of agent causation, though emphatically not in defence of an account of free will, as most theories of (...) agent causation are. Rather, I argue that the notion of agent causation introduced here best explains how it is that you are making your body move during an action, thereby providing a satisfactory solution to the problem of action.

Many authors have argued in favour of an ontology of properties as powers, and it has been widely argued that this ontology allows us to address certain philosophical problems in novel and illuminating ways, for example, causation, representation, intentionality, free will and liberty. I argue that the ontology of powers, even if successful as an account of fundamental natural properties, does not provide the insight claimed as regards the aforementioned non-fundamental phenomena. I illustrate this argument by criticizing the powers theory (...) of causation presented by Mumford and Anjum and showing that related criticisms can be directed at other abuses of powers. (shrink)

The Physical Intentionality Thesis claims that dispositions share the marks of psychological intentionality; therefore, intentionality is not exclusively a mental phenomenon. Beyond the standard five marks, Alexander Bird introduces two additional marks of intentionality that he argues dispositions do not satisfy: first, thoughts are extrinsic; second, the direction of causation is that objects cause thoughts, not vice versa. In response, this paper identifies two relevant conceptions of extrinsicness, arguing that dispositions show deep parallels to thoughts on both conceptions. Then, it (...) shows that Bird’s discussion of direction of causation overlooks complexities of dispositionality and intentionality that problematize apparent differences between thoughts and dispositions. The paper ends with a discussion of why we find these parallels between thoughts and dispositions. (shrink)

If the universe and God are identical, as pantheism holds, how can we reconcile the supposed unity of God with the apparent dis-unity of the universe’s elements? I argue that a powers ontology, which generates a form of pantheism under plausible assumptions, is apt to solve the problem of unity. There is reason to think that the directedness of powers is equivalent to the directedness, or intentionality, of mental states. This implies that intentionality is a feature of the physical world (...) at large, not just the mind. As Pfeifer argues, this physical intentionality represents a mild form of panpsychism that is interpretable as a brand of pantheism. I argue that the theory of powers holism explains the unity of the universe’s elements and thus the unity of a pantheistic God, and that powers holism is strengthened by fully recognizing the role of physical intentionality.

Dispositional essentialism maintains that all sparse properties are essentially powerful. Two conceptions of sparse properties appear compatible with dispositional essentialism: sparse properties as pure powers or as powerful qualities. This paper compares the two views, criticizes the powerful qualities view, and then develops a new theory of pure powers, termed Point Theory. This theory neutralizes the main advantage powerful qualities appear to possess over pure powers—explaining the existence of powers during latency periods. The paper discusses the relation between powers and (...) space-time points, whether pure powers need to occupy space, and how to account for the movement of pure powers through space-time. Given Point Theory, dispositional essentialists should maintain that sparse properties are pure powers. (shrink)

This paper examines the need for static dispositions within the basic ontology of the powers view of properties. To lend some focus, Neil Williams’s well developed case for static dispositions is considered. While his arguments are not necessarily intended to address fundamental ontology, they still provide a useful starting point, a springboard for diving into the deeper metaphysical waters of the dispositionalist approach. Within that ontological context, this paper contends that Williams’s arguments fail to establish the need to posit static (...) dispositions, or at least any sort not already well appreciated by advocates of the powers view. The paper then proceeds to suggest an alternative motivation for positing static dispositions, the success of which depends greatly on which ontological approach to objects is paired with the powers view.

In his recent book, The Universe As We Find It, John Heil offers an updated account of his two-category ontology. One of his major goals is to avoid including relations in his basic ontology. While there can still be true claims positing relations, such as those of the form “x is taller than y” and “x causes y,” they will be true in virtue of substances and their monadic, non-relational properties. That is, Heil’s two-category ontology is deployed to provide non-relational (...) truthmakers for relational truths. This paper challenges the success of Heil’s project with respect to causation. The arguments here are not entirely negative, however. An option is made available to Heil’s ontology so that it might, at least to some extent, regain non-relational causings. (shrink)

Neuron diagrams are heavily employed in academic discussions of causation. Stephen Mumford and Rani Lill Anjum, however, offer an alternative approach employing vector diagrams, which this paper attempts to develop further. I identify three ways in which dispositionalists have taken the activities of powers to be related: stimulation, mutual manifestation, and contribution combination. While Mumford and Anjum do provide resources for representing contribution combination, which might be sufficient for their particular brand of dispositionalism, I argue that those resources are not (...) flexible enough to further accommodate either stimulation or mutual manifestation. Representational tools are provided to address these limitations, improving the general value of the vector model for dispositionalist approaches to causation. (shrink)

In taking properties to have powerful or dispositional essences, dispositionalism is primed to provide an account of causation. This paper lays out a challenge confronting the dispositionalist’s ability to account for how powers causally interact with one another so as to bring about collective results. The challenge, here labeled the “interaction gap,” is raised for two competing kinds of approaches to dispositional interaction: contribution combinationist and mutual manifestationist. After carefully highlighting and testing potential resources for closing the interaction gap, it (...) is concluded that the mutual manifestationist approach holds a significant advantage. In turn, the importance of the interaction gap itself is highlighted. While powers prime an ontology to yield an account of causation, how far that account can actually go depends on the metaphysical details of one’s view of powers and their causal interaction.

In recent years, a new dispute has risen to prominence: the dispute between realists and anti-realists about causal powers. Albeit sometimes overlooked, the meta-ontological features of this “question of realism for powers” are quite peculiar. For friends and foes of causal powers have characterized their contrasting views in a variety of different ways; as existence claims, as semantic or truth-making claims, as fundamentality claims, as claims about the nature of certain properties. Not only does this multiplicity of interpretations make it (...) unclear what the genuine bone of contention is, if there is one; some of them appear to be mutually exclusive. Some light can be shed on this apparent yet widespread confusion by distinguishing three degrees of ontological involvement in dispositional truths; viz., three ways, of increasing robustness, to read ontological commitments from dispositional truths. Relatedly, by exploring the literature, and focusing on some selected examples of power realism and anti-realism, we can observe that power realists vastly disagree over the intrinsic nature ad make-up of dispositional properties. Such examples furthermore invite the thought that the question of realism for powers is best understood not as the debate around the existence of properties with a distinctive identity, but rather as a debate about metaphysical hierarchy. Finally, some anti-realists positions are indistinguishable from realist ones, using merely intensional resources: power realism is best appreciated by going hyperintensional. (shrink)

Discussions about dispositional and categorical properties have become commonplace in metaphysics. Unfortunately, dispositionality and categoricity are disputed notions: usual characterizations are piecemeal and not widely applicable, thus threatening to make agreements and disagreements on the matter merely verbal—and also making it arduous to map a logical space of positions about dispositional and categorical properties in which all parties can comfortably fit. This paper offers a prescription for this important difficulty, or at least an inkling thereof. This will be achieved by (...) comparing pairs of positions and exploring their background metaphysics to discover where alleged agreements and disagreements concerning dispositionality and categoricity really lie; more specifically, the Pure Powers view and the Powerful Qualities view will be under scrutiny. Over this background, the prescription functions by isolating a successful identity-based characterization of categoricity, while abandoning the correspondent identity-based characterization of dispositionality. On the contrary, according to this prescription a property is dispositional if and only if it is solely in virtue of possessing that property that its bearer is assigned a certain dispositional profile. A crucial consequence of this prescription is that, while supporters of the Pure Powers view often characterize their position as an essentialist one, the dispositionality of properties needn’t always be a matter of essence.

According to the proponents of Developmental Systems Theory and the Causal Parity Thesis, the privileging of the genome as “first among equals” with respect to the development of phenotypic traits is more a reflection of our own heuristic prejudice than of ontology - the underlying causal structures responsible for that specified development no more single out the genome as primary than they do other broadly “environmental” factors. Parting with the methodology of the popular responses to the Thesis, this paper offers (...) a novel criterion for ‘causal primacy’, one that is grounded in the ontology of the unique causal role of dispositional properties. This paper argues that, if the genome is conceptualised as realising dispositional properties that are “directed toward” phenotypic traits, the parity of ‘causal roles’ between genetic and extra-genetic factors is no longer apparent, and further, that the causal primacy of the genome is both plausible and defensible.

Evolutionary developmental biology represents a paradigm shift in the understanding of the ontogenesis and evolutionary progression of the denizens of the natural world. Given the empirical successes of the evo-devo framework, and its now widespread acceptance, a timely and important task for the philosophy of biology is to critically discern the ontological commitments of that framework and assess whether and to what extent our current metaphysical models are able to accommodate them. In this paper, I argue that one particular model (...) is a natural fit: an ontology of dispositional properties coherently and adequately captures the crucial casual-cum-explanatory role that the fundamental elements of evo-devo play within that framework.

The advent of contemporary evolutionary theory ushered in the eventual decline of Aristotelian Essentialism (Æ) – for it is widely assumed that essence does not, and cannot have any proper place in the age of evolution. This paper argues that this assumption is a mistake: if Æ can be suitably evolved, it need not face extinction. In it, I claim that if that theory’s fundamental ontology consists of dispositional properties, and if its characteristic metaphysical machinery is interpreted within the framework (...) of contemporary evolutionary developmental biology, an evolved essentialism is available. The reformulated theory of Æ offered in this paper not only fails to fall prey to the typical collection of criticisms, but is also independently both theoretically and empirically plausible. The paper contends that, properly understood, essence belongs in the age of evolution. (shrink)

Omissions are sometimes linked to responsibility. A harm can counterfactually depend on an omission to prevent it. If someone had the ability to prevent a harm but didn’t, this could suffice to ground their responsibility for the harm. Michael S. Moore’s claim is illustrated by the tragic case of Peter Parker, shortly after he became Spider-Man. Sick of being pushed around as a weakling kid, Peter became drunk on the power he acquired from the freak bite of a radioactive spider. (...) When a police officer called to Spider-Man to stop an escaping burglar, which he could have done easily, he failed to act. He was through taking orders. The omission was followed by a crime. That very same burglar later robbed Peter’s own house and when challenged he shot dead Peter’s Uncle Ben. Later, Spider-Man tracked down the killer and, when seeing his face close up, the possibility of prevention dawned on him. He could have stopped this crook and had he done so Uncle Ben would still be alive. Stan Lee’s tale of power finished with a Shakespearean twist. Young Peter realised the truth of the WGPCGR-thesis: With Great Power Comes Great Responsibility. We too will endorse the WGPCGR-thesis. There is a close connection between our notions of moral and legal responsibility and the powers we have as causal agents. This will be particularly important when it comes to the case of omissions: where we had the power to act but failed to do so. We hope to show the connections between the notions of power, cause, act, omission and responsibility but also some of the nuances. We will do so with particular reference to Moore’s account in Causation and Responsibility. (shrink)

Do conceivability arguments work against physicalism if properties are causal powers? By considering three different ways of understanding causal powers and the modality associated with them, I will argue that most, if not all, physicalist powers theorists should not be concerned about the conceivability argument because its conclusion that physicalism is false does not hold in their favoured ontology. I also defend specific powers theories against some recent objections to this strategy, arguing that the conception of properties as powerful blocks (...) conceivability arguments unless a rather implausible form of emergence is true.

Panpsychism is viewed by its advocates as resolving the main sticking points for materialism and dualism. While sympathetic to this approach, I locate two prevalent assumptions within modern panpsychism which I think are problematic: first, that fundamental consciousness belongs to a perspectival subject and second, that the physical world, despite being backed by conscious subject, is observer-independent. I re-introduce an argument I’d made elsewhere against the first assumption: that it lies behind the well-known combination and decombination problems. I then propose (...) a new argument against the second assumption: that it leads to an equally pernicious difficulty I call the “Inner-Outer Gap Problem.” The variant of panpsychism I continue to develop and defend, Perennial Idealism, avoids these assumptions and their problems, allowing real progress on the mind-body problem. Perennial Idealism is a type of panpsychist idealism rather than panpsychist materialism. (shrink)
