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 this article, I challenge the dominant view of the importance of the debate over action-individuation. On the dominant view, it is held that the conclusions we reach about action-individuation make little or no difference for other debates in the philosophy of action, much less in other areas of philosophy. As a means of showing that the dominant view is mistaken, I consider the implications of accepting a given theory of action-individuation for thinking about doxastic agency. In particular, I am (...) interested in the implications for thinking about the variety of evaluative control we can exercise over the formation of our doxastic attitudes. I show that our assumptions about how to individuate actions matters for how we think about doxastic agency and, hence, the conclusions we reach about action-individuation are of greater significance than some have thought.

– The paper defends a naturalistic version of modal actualism according to which what is metaphysically possible is determined by dispositions found in the actual world. We argue that there is just one world—this one—and that all genuine possibilities are anchored by the dispositions exemplified in this world. This is the case regardless of whether or not those dispositions are manifested. As long as the possibility is one that would obtain were the relevant disposition manifested, it is a genuine possibility. (...) Furthermore, by starting from actual dispositional properties and branching out, we are able to include possibilities that are quite far removed from any state of affairs that happens to obtain, while still providing a natural and actual grounding of possibility. Stressing the importance of ontological considerations in any theory of possibility, it is argued that the account of possibility in terms of dispositional properties provides a more palatable ontology than those of its competitors. Coming at it from the other direction, the dispositional account of possibility also provides motivation for taking an ontology of dispositions more seriously. As well as the relevant dispositional notions required to lay out the view, the paper discusses the dispositional realism needed as the basis for the account of possibility. (shrink)

Dispositional monism is the view that natural properties and relations are ‘pure powers’. It is objected that dispositional monism involves some kind of vicious or otherwise unpalatable regress or circularity. I examine ways of making this objection precise. The most pressing interpretation is that is fails to make the identities of powers determinate. I demonstrate that this objection is in error. It does however puts certain constraints on what the structure of fundamental properties is like. I show what a satisfactory (...) structure would be. (shrink)

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)

Powers have in recent years become a central component of many philosophers’ ontology of properties. While I have argued that powers exist at the fundamental level of properties, many other theorists of powers hold that there are also non-fundamental powers. In this paper I articulate my reasons for being sceptical about the existing reasons for holding that there are non-fundamental powers. However, I also want to promote a different argument for the existence of a certain class of non-fundamental powers: properties (...) which have natural selection to thank for their existence and nature. Such properties will include functional properties of organisms, and so may also include their mental properties. (shrink)

Here we challenge the orthodoxy according to which abduction is an a posteriori mode of inference. We start by providing a case study illustrating how abduction can justify a philosophical claim not justifiable by empirical evidence alone. While many grant abduction's epistemic value, nearly all assume that abductive justification is a posteriori, on grounds that our belief in abduction's epistemic value depends on empirical evidence about how the world contingently is. Contra this assumption, we argue, first, that our belief in (...) abduction’s epistemic value is not and could not be justified a posteriori, and second, that attention to the roles experience plays in abductive justification supports taking abduction to be an a priori mode of inference. We close by highlighting how our strategy for establishing the a priority of abduction positively contrasts with strategies in Bonjour (1998), Swinburne (2001), and Peacocke (2004) aiming to establish the a priority of certain ampliative modes of inference or abductive principles.

In this article, I am interested in dual-aspect monism as a solution to the mind-body problem. This view is not new, but it is somewhat under-represented in the contemporary debate, and I would like to help it make its way. Dual-aspect monism is a parsimonious, elegant and simple view. It avoids problems with “mental causation”. It naturally explains how and why mental states are correlated with physical states while avoiding any mysteries concerning the nature of this relation. It fits well (...) with our ordinary picture of the world, as well as with the scientific picture. It gives its rightful place to the phenomenal, qualitative, subjective character of experience, instead of reducing it or eliminating it. It does not unnecessarily multiply ontological categories. It can come in many versions, and is compatible with other interesting views, such as panpsychism. (shrink)

According to one-level physicalism, reality is exhausted by fundamental physical entities and properties. This position is sometimes defended on the basis of the truthmaker view of ontological commitment. Accordingly, physicalists can affirm higher-level truths without ontologically committing to any higher-level properties or states of affairs; fundamental physical states of affairs serve as truthmakers of all truths that have truthmakers, and a physicalist’s ontology should consist of nothing but the fundamental physical states of affairs and their constituents. In this paper, I (...) raise a problem for one-level physicalists who defend their views by appealing to the truthmaker view of ontological commitment. I argue that the truthmaker view faces certain puzzles the solutions of which clash with the main tenets of one-level physicalism. I conclude that either truthmaking is not a good guide to ontological commitment or one-level physicalism cannot be defended on the basis of the truthmaker view. (shrink)

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

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)

Several philosophers of science and metaphysicians claim that the dispositional properties of fundamental particles, such as the mass, charge, and spin of electrons, are ungrounded in any further properties. It is assumed by those making this argument that such properties are intrinsic, and thus if they are grounded at all they must be grounded intrinsically. However, this paper advances an argument, with one empirical premise and one metaphysical premise, for the claim that mass is extrinsically grounded and is thus an (...) extrinsic disposition. Although the argument concerns mass characterized as a disposition, it applies equally well whether mass is a categorical or dispositional property; however, the dispositional nature of mass is relevant to some important objections and implications discussed. (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)

In this paper I develop a framework for understanding ontic vagueness. The project of the paper is two-fold. I first outline a definitional account of ontic vagueness – one that I think is an improvement on previous attempts because it remains neutral on other, independent metaphysical issues. I then develop one potential manifestation of that basic definitional structure. This is a more robust (and much less neutral) account which gives a fully classical explication of ontic vagueness via modal concepts. The (...) overarching aim is to systematically investigate the puzzling question of what exactly it could be for the world itself to be vague. (shrink)

John goes out for a walk. If John endures and his walk perdures, they are different entities. However, what if both John and his walk perdure? Is John’s walk identical to his relevant temporal part? Some philosophers answer in the affirmative. Their motivations rest on ontological parsimony and the quest for clear-cut identity criteria for existing things. By contrast, one of the most widely accepted theories of events – the theory of events as property-exemplifications – allows us to formulate an (...) argument to the effect that objects’ temporal parts are distinct from the events they participate in: the AID argument, as I shall call it. In this paper, I argue that accepting austere nominalism is the best strategy a supporter of the identification between events and temporal parts of objects can take in order to resist the AID argument. (shrink)

Recently, nominalists have made a case against the Quine–Putnam indispensability argument for mathematical Platonism by taking issue with Quine’s criterion of ontological commitment. In this paper I propose and defend an indispensability argument founded on an alternative criterion of ontological commitment: that advocated by David Armstrong. By defending such an argument I place the burden back onto the nominalist to defend her favourite criterion of ontological commitment and, furthermore, show that criterion cannot be used to formulate a plausible form of (...) the indispensability argument.

Neutral monism is a position in metaphysics defended by Mach, James, and Russell in the early twentieth century. It holds that minds and physical objects are essentially two different orderings of the same underlying neutral elements of nature. This paper sets out some of the central concepts, theses and the historical background of ideas that inform this doctrine of elements. The discussion begins with the classic neutral monism of Mach, James, and Russell in the first part of the paper, then (...) considers recent neo-Russellian versions in the second half. The chances for a revival of neutral monism are probably slight; its key ideas and starting points lie far from those in contemporary philosophy of mind. A better route might be through the philosophy of science and a deeper understanding of causation. (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 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 dispositionalism, de re modality is grounded in the intrinsic natures of dispositional properties. Those properties are able to serve as the ground of de re modal truths, it is said, because they bear a special relation to counterfactual conditionals, one of truthmaking. However, because dispositionalism purports to ground de re modality only on the intrinsic natures of dispositional properties, it had better be the case that they do not play that truthmaking role merely in virtue of their being (...) embedded in some particular, extrinsic causal context. This paper examines a recent argument against dispositionalism that purports to show that the intrinsicality of that relation cannot be maintained, due to the ceteris paribus nature of the counterfactuals that dispositions make-true. When two prominent responses are examined, both are found wanting: at best, they require unjustified special pleading, and at worst, they amount to little more than ad hoc conceptual trickery.

Are there disjunctive properties? This question is important for at least two reasons. First, disjunctive properties are invoked in defense of certain philosophical theories, especially in the philosophy of mind. Second, the question raises the prior issue of what counts as a genuine property, a central concern in the metaphysics of properties. I argue here, on the basis of general considerations in the metaphysics of properties, that there are no disjunctive properties. Specifically, I argue that genuine properties must guarantee similarity-in-a-respect (...) among their instances, and must inhere in their bearers (two notions to be clarified). Disjunctive properties would fail both requirements. I compare the case of disjunctive properties with “mere Cambridge properties,” determinable properties, and functional properties, and show how my conception of properties remains compatible with determinables and functional properties while ruling out disjunctive and mere Cambridge properties.

ABSTRACT This paper discusses three aspects of Karen Bennett’s theory of building relations, as articulated in her book Making Things Up: the inclusion of causation among the building relations, the denial that non-fundamental things add to the complexity of a theory, and the claim that building relations are one-sided relations that are themselves built. Section 1 gives a brief overview. Section 2 seeks to motivate a distinction between building relations and making relations, and questions whether the deep structural similarities among (...) building relations has the methodological consequences that Bennett claims. Section 3 argues against the claim that considerations of ontological simplicity in theory choice are restricted to non-fundamental entities. Section 4 raises objections to the idea of a one-sided building relation. (shrink)

Realism and anti-realism about a domain of thought are metaphysical theses that involve the natures of the truthmakers in that domain and the truthmaking relation that is operant in the domain. Truthmaker theory is not exclusive territory for realists: anti-realist views are also best understood in terms of how they understand truthmakers and truthmaking. In particular, I explore the possibility of projectivist truthmaking, and show how it makes sense of quasi-realism. In addition to critically examining some extant accounts of the (...) relationship between realism and truthmaking, I offer an account that best captures the nature of the various realism debates.

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.

un estado de cosas es una estructura no-mereológica compuesta por universales, objetos y tiempos. En principio, un estado de cosas no está fundado en sus componentes, pues tales componentes podrían existir, pero no el estado de cosas que componen. La introducción de otras relaciones de 'instanciación' no mejoran la situación, si tales relaciones son universales. Un estado de cosas, sin embargo, sí está fundado en un universal, uno o varios objetos, un tiempo y un tropo que, esencialmente, es la instanciación (...) de tal universal en tal objeto, o en tales objetos, en tal tiempo. Si los estados de cosas están fundados en sus constituyentes, entonces hay una razón para admitir tropos. Finalmente, se discuten varias razones por los que los estados de cosas deben estar fundados. a state of affairs is a non-mereological structure composed by universals, objects and times. In principle, a state of affairs is not grounded in its components, for those components could exist, but not the state of affairs that they compose. The introduction of other relations of 'instantiation' doesn't improve the situation, if those relations are universal. A state of affairs, though, is grounded on a universal, object or objects, time and a trope that, essentially, is the instantiation of that universal in that object, or in those objects, in that time. If states of affairs are grounded in their constituents, then there is reason to admit tropes. Finally, several reasons by which states of affairs should be grounded are discussed. (shrink)

A ‘state of affairs’ is understood here as any kind of concrete entity that can play the role of truthmaker. Different ontologies propose different structures of entities to work as ‘states of affairs’ in this sense. Defenders of universals will propose for the role non- mereological structures of universals, objects and times. Defenders of tropes will propose tropes, either with or without universals and objects. Resemblance nominalists will propose primitive ontological facts of resemblance between objects in time. In any of (...) these cases, times are an essential component of a state of affairs. Any ontology of states of affairs, then, should clarify what times are in order to clarify what states of affairs are. An examination of the dominant reductivist conceptions of times shows that these connections have not yet been thought through carefully. In any of the dominant reductivist conceptions, times are entities that either include or describe everything that happens simultaneously at a given instant. Even in some cases they include the description of everything that happens at any time. If one introduce times taken as they are in any of these reductivist conceptions, it will be essential to a state of affairs everything that happens simultaneously with it, or even everything that happens at any time. Under some assumptions the internal relation of every state of affairs with every other state of affairs expands to the internal relation of everything with everything. This is an unhappy theoretical situation that calls for a more careful consideration of some central tenets in our ontology of time. (shrink)

In his conceivability argument, Chalmers assumes that all properties have their causal powers contingently and causal laws are also contingent. We argue that this claim conflicts with how conceivability itself must work for the conceivability argument to be successful. If conceivability is to be an effective mechanism to determine possibility, it must work as a matter of necessity, since contingent conceivability renders conceivability fallible for an ideal reasoner and the fallible conceivability of zombies would not entail their possibility. But necessary (...) conceivability must either be governed by necessitating causal processes or by a necessitating non-causal mechanism. We argue that the latter option is untenable or mysterious; whereas, if Chalmers chooses the former and applies it only to conceivability, his solution is ad hoc, but if he accepts necessary causal powers or processes generally, the conceivability argument fails. We conclude that, as it stands, the Conceivability Argument does not establish that physicalism is false. (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.

A critical survey of the main metaphysical theories concerning the nature of material objects (substratum theories, bundle theories, substance theories, stuff theories) and their identity conditions, both synchronic (monist vs. pluralist theories) and diachronic (three-dimensionalism, four-dimensionalism, sequentialism).

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)

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.

I defend a reading of David Hume’s nominalism that he comes close to Keith Campbell's contemporary trope theory in the specific case of spatial properties. I argue that Hume's view should be construed as classifying spatial properties as Campbellian tropes (particular properties): abstract, particular, determinate and qualitatively simple properties. This has implications for reconstructing Hume's answer to the problem of universals. I argue that Hume’s account of objects resembling each other in respect of spatial properties is grounded in the resemblance (...) of tropes rather than in the resemblance of objects. (shrink)

In this paper, I first introduce one of the most prominent objections against the Growing Block Theory of time (GBT), the so-called ‘epistemic objection’, according to which GBT provides no way of knowing that our time is the objective present and, therefore, leads at best to absolute skepticism about our temporal location, at worst to the quasi-certainty that we are located in the objective past. Secondly, I express my dissatisfaction regarding the various traditional attempts to address this objection, especially Merricks (...) (2006), Forrest (2004) and Correia and Rosenkranz (2018). Thirdly, I show that the passage of time leads to an anti-essentialist picture of natural kinds. Finally, I develop my own solution to the epistemic objection, based on the continued existence of bare particulars. (shrink)

Distinctively mathematical explanations (DMEs) explain natural phenomena primarily by appeal to mathematical facts. One important question is whether there can be an ontic account of DME. An ontic account of DME would treat the explananda and explanantia of DMEs as ontic structures and the explanatory relation between them as an ontic relation (e.g., Pincock 2015, Povich 2021). Here I present a conventionalist account of DME, defend it against objections, and argue that it should be considered ontic. Notably, if indeed it (...) is ontic, the conventionalist account seems to avoid a convincing objection to other ontic accounts (Kuorikoski 2021). (shrink)

Scientific realists argue that a good track record of multi-agent, and multiple method, validation of empirical claims is itself evidence that those claims, at least partially and approximately, reflect ways nature actually is independent of the ways we conceptualize it. Constructivists contend that successes in validating empirical claims only suffice to establish that our ways of modelling the world, our “constructions,” are useful and adequate for beings like us. This essay presents a thought experiment in which beings like us intersubjectively (...) validate claims about properties of particular things in nature under conditions in which those beings have profoundly different personal phenomenological experiences of those properties. I submit that the thought experiment scenario parallels our actual situation, and argue that this shows that successes in intersubjectively validating empirical claims are indeed enough to claim victory for the realist. More specifically, I champion a variation of realism that marries Ronald Giere’s brand of ‘perspectival realism’ with Philip Kitcher’s ‘real realism,’ and posits that causal relations between ourselves and properties instantiated in nature ground our references to the relevant properties even though our conceptions of them are perspective relative.

ABSTRACT One of the core issues where interpreters of Kant disagree concerns his alleged Noumenalism—the claim that the objects of our experience, which are in space and time, are underpinned by entities that are not spatio-temporal and that non-spatio-temporally cause our representations of empirical objects. Although there is much textual evidence in favour of Noumenalism, non-Noumenalists have also gathered a significant number of philosophical and exegetical challenges to such a reading of Kant. I present a novel way of understanding the (...) Noumenalist view, which characterises the distinction between appearances and things in themselves as the distinction between referents and truthmakers. I show that, on this interpretation of Kant, the most pressing problems for the Noumenalist reading are primarily based on equivocations between features of reference and features of truthmaking.

The system of realist philosophy developed by John Anderson — situational realism — has recently been dismissed as ‘positivist’ by a prominent critical realist. The reason for this dismissal appears not to be the usual list of ideas deemed positivist, but the conviction that situational realism mistakenly defends a form of actualism, i.e. that to conceive of causal laws as constant conjunctions reduces the domain of the real to the domain of the actual. This is, in part, a misreading of (...) Anderson’s philosophy because, contrary to Hume’s constant conjunction account, Anderson viewed causation as pluralistic and non-linear. However, the critical realist charge does point to two important ontological differences between these realist philosophies — a levels-of-reality thesis and the notion of causal powers. Situational realism has always maintained that the arguments for both lead to difficulties that are logically insurmountable. Unfortunately, this is not addressed in the critical realists’ dismissal of Anderson’s philosophy. Regardless of who makes the charge of positivism, it frequently involves inattention to the real character of its target. (shrink)

Spacetime functionalism is the view that spacetime is a functional structure implemented by a more fundamental ontology. Lam and Wüthrich have recently argued that spacetime functionalism helps to solve the epistemological problem of empirical coherence in quantum gravity and suggested that it also (dis)solves the hard problem of spacetime, namely the problem of offering a picture consistent with the emergence of spacetime from a non-spatio-temporal structure. First, I will deny that spacetime functionalism solves the hard problem by showing that it (...) comes in various species, each entailing a different attitude towards, or answer to, the hard problem. Second, I will argue that the existence of an explanatory gap, which grounds the hard problem, has not been correctly taken into account in the literature. (shrink)

Dispositional monists believe that all properties are essentially causal. Recently, an overdetermination argument has been proposed by Trenton Merricks to support nihilism about ordinary objects. I argue that this argument can be extended to target both nihilism about ordinary objects and nihilism about physical particles when dispositional monism is assumed. It implies that a philosopher who both endorses dispositional monism and takes seriously the overdetermination argument should not believe in the existence of physical particles. I end up by discussing possible (...) objections. I suggest, then, that if we live in a world that is inhabited by causal properties but not by chairs and tables, then we also live in a world without electrons and quarks, a world of dispositional properties, that is, a world of causal fields.
