We argue that Armstrong's Combinatorialism allows for the possibility of nothing by giving a Combinatorial account of the empty world and show that such an account is consistent with the ontological and conceptual aims of the theory. We then suggest that the Combinatorialist should allow for this possibility given some methodological considerations. Consequently, rather than being 'spoils for the victor', as Armstrong maintains, deciding whether there might have been nothing helps to determine which metaphysics of modality is to be preferred.

One of the many ways that ‘deflationary’ and ‘inflationary’ theories of truth are said to differ is in their attitude towards truth qua property. This difference used to be very easy to delineate, with deflationists denying, and inflationists asserting, that truth is a property, but more recently the debate has become a lot more complicated, owing primarily to the fact that many contemporary deflationists often do allow for truth to be considered a property. Anxious to avoid inflation, however, these deflationists (...) are at pains to point out that the truth property, on their view, is not a property of any significant interest. Correspondingly, inflationists have seen this as an opportunity to refine what kind of property they think truth is, which—according to them—moves their views beyond deflationism. The upshot of this is that there are number of different accounts in the literature of what distinguishes an inflationary truth property from a deflationary one, or—as it is sometimes put—what distinguishes a ‘substantive’ property from an ‘insubstantive’ one. This has made it hard to pin down exactly what is at issue at the metaphysical level between deflationists and inflationists, which makes it increasingly hard to see how debates between them are properly phrased. Given that these positions represent the two central attitudes towards truth in contemporary debates, this makes for a serious obstacle for the project of discerning the correct theory of truth. The aim of this paper is to discern the best way to distinguish between substantive and insubstantive properties, and thus to restore some focus to these debates. I argue that the three central distinctions in the literature fail, and offer what I take to be a more promising distinction in terms of a graded distinction between abundant and sparse properties.

In these replies I develop responses to the fascinating issues raised in the commentaries on my book The Metaphysics of Truth from Matti Eklund, Gila Sher, Crispin Wright, and Jeremy Wyatt. I focus on four main areas where there seemed to be a degree of convergence amongst the critics: (1) the viability and use of the sparse/abundant property distinction; (2) truth, dependence, and superassertibility; (3) correspondence, realism, and anti—realism; and (4) my ‘globalizing’ argument against deflationism.

Fitch’s argument purports to show that for any unknown truth, p , there is an unknowable truth, namely, that p is true and unknown; for a contradiction follows from the assumption that it is possible to know that p is true and unknown. In earlier work I argued that there is a sense in which it is possible to know that p is true and unknown, from a counterfactual perspective; that is, there can be possible, non-actual knowledge, of the actual (...) situation, that in that situation, p is true and unknown. Here I further elaborate that claim and respond to objections by Williamson, who argued that there cannot be non-trivial knowledge of this kind. I give conditions which suffice for such non-trivial counterfactual knowledge. (shrink)

In "Does Four-Dimensionalism Explain Coincidence" Mark Moyer argues that there is no reason to prefer the four-dimensionalist (or perdurantist) explanation of coincidence to the three-dimensionalist (or endurantist) explanation. I argue that Moyer's formulations of perdurantism and endurantism lead him to overlook the perdurantist's advantage. A more satisfactory formulation of these views reveals a puzzle of coincidence that Moyer does not consider, and the perdurantist's treatment of this puzzle is clearly preferable.

Is part of a perfectly natural, or fundamental, relation? Philosophers have been hesitant to take a stand on this issue. One reason for this hesitancy is the worry that, if parthood is perfectly natural, then the perfectly natural properties and relations are not suitably “independent” of one another. In this paper, I argue that parthood is a perfectly natural relation. In so doing, I argue that this “independence” worry is unfounded. I conclude by noting some consequences of the naturalness of (...) parthood. (shrink)

The standard counterexamples to David Lewis’s account of intrinsicality involve two sorts of properties: identity properties and necessary properties. Proponents of the account have attempted to deflect these counterexamples in a number of ways. This paper argues that none of these moves are legitimate. Furthermore, this paper argues that no account along the lines of Lewis’s can succeed, for an adequate account of intrinsicality must be sensitive to hyperintensional distinctions among properties.

Correia and Rosenkranz (C&R) defend their Growing Block theory of time by appealing to the importance of the notion of taking tense seriously. I argue that this phrase is ambiguous, having both a linguistic and a metaphysical interpretation, but neither interpretation will give C&R what they need. On its linguistic interpretation it fails to have the metaphysical significance required to establish the truth of their theory. On its metaphysical interpretation it consists of nothing more than an assertion of their view, (...) or at best, an acknowledgement of its merely possible truth. Finally, I consider C&R’s response to the epistemic objection to their view, according to which, if the Growing Block theory is true, we cannot know that we are located at the objective present moment. The epistemic objection thus undermines the motivation for holding the Growing Block view in the first place. C&R argue that the objection founders because it fails to take tense seriously enough. I argue that taking tense seriously cannot save their view from the epistemic objection. (shrink)

Some philosophers claim that propositions are simple—i.e., lack parts. In this paper, I argue that this claim is mistaken. I start with the widely accepted claim that propositions are the objects of beliefs. Then I argue that the objects of beliefs have parts. Thus, I conclude that propositions are not simple. My argument for the claim that the objects of beliefs have parts derives from the fact that beliefs are productive and systematic. This fact lurks in the background of debates (...) about the metaphysics of propositions. But its import for these debates has yet to be fully appreciated. So here I bring the point to the fore, and thus make manifest a powerful argument against simple propositions. (shrink)

David Lewis ([1986b]) gives an attractive and familiar account of counterfactual dependence in the standard context. This account has recently been subject to a counterexample from Adam Elga ([2000]). In this article, I formulate a Lewisian response to Elga’s counterexample. The strategy is to add an extra criterion to Lewis’s similarity metric, which determines the comparative similarity of worlds. This extra criterion instructs us to take special science laws into consideration as well as fundamental laws. I argue that the Second (...) Law of Thermodynamics should be seen as a special science law, and give a brief account of what Lewisian special science laws should look like. If successful, this proposal blocks Elga’s counterexample. (shrink)

In both the historical and contemporary literature on the metaphysics of space, a core dispute is that between relationism and substantivalism. One version of the latter is supersubstantivalism, according to which space is the only kind of substance, such that what we think of as individual material objects are actually just parts of spacetime which instantiate certain properties. If those parts are ontologically dependent on spacetime as a whole, then we arrive at an ontology with only a single genuinely independent (...) substance, namely the entire spacetime manifold. This is monist supersubstantivalism. A view on which the parts of spacetime are ontologically prior to the whole has been called pluralistic supersubstantivalism. As currently formulated, supersubstantivalism carries significant advantages and encounters major difficulties. I argue that some of the latter motivate... (shrink)

The four principal competing substance ontologies are substratum theory, bundle theory, primitive substance theory, and hylomorphism. Both historically and in the recent literature, most arguments pertaining to these four theories have been developed under the assumption that only one of them can be true. However there is room in this debate for various forms of pluralism: mild pluralism here refers to the view that while only one of these four theories is true of our world, there is at least one (...) other possible world in which a different substance ontology obtains; moderate pluralism refers to the view that while only one of these four theories is true of our world, there is at least one other possible world in which multiple substance ontologies obtain ; and extreme pluralism refers to the view that our own actual world contains substances belonging to different substance ontologies. In this paper I lay out a novel argument for a version of extreme pluralism. (shrink)

Symmetry principles are a central part of contemporary physics, yet there has been surprisingly little metaphysical work done on them. This article develops the Wignerian treatment of symmetries as higher-order laws—metalaws—within a Humean framework of lawhood. Lange has raised two obstacles to Humean metalaws, and the article shows that the account has the resources available to respond to both. It is argued that this framework for Humean metalaws stands as an example of naturalistic metaphysics, able to bring Humeanism into contact (...) with the practice of actual science without giving up on the central denial of necessary connections.

The hypothesis that we may be living in a digital simulation is utilized as a ‘thought experiment’ to help clarify important questions in theology and philosophy, including the nature of God, the significance and importance of an afterlife, and the ultimate nature of reality. It is argued that a consideration of the simulation hypothesis renders problematic traditional conceptions of a personal, creator, omnipotent deity, makes the theological significance of a purported afterlife far less significant, and paradoxically undermines the very materialistic (...) view of reality that underlies the simulation hypothesis in the first place. It is concluded that the simulation hypothesis renders ‘science’ virtually irrelevant to ultimate questions in philosophy and theology and elevates ethics and axiology to fundamental status for our understanding of reality and any defensible conception of the divine.

What grounds the truth of modal statements? And how do we get to know about what is possible or necessary? One of the most prominent anti-realist perspectives on the nature of modality, due to Peter Menzies, is the response-dependent account of modal concepts. Typically, offering a response-dependent account of a concept means defining it in terms of dispositions to elicit certain mental states from suitable agents under suitable circumstances. Menzies grounded possibility and necessity in the conceivability-response of ideal conceivers: P (...) is possible iff an ideal conceiver could conceive that P. I will draw attention to three major objections that can be identified in the modal metaphysics and epistemology literature: Chalmers’ Incoherency Objection, Sherratt’s Transparency Objection and Geirsson’s Irrelevancy Objection. Each of these objections raises a different worry regarding Menzies’ account: that the notion of an ideal conceiver is incoherent, that the account implies a controversial thesis, and that it fails to offer an explanation of our knowledge of modality. The aim of this paper is to defend the response-dependent account of modality against these three objections. (shrink)

Drawing on Earman’s definition of determinism and Lewis’ best systems account of laws, in What Makes Time Special? Craig Callender develops an account of time as ‘the strongest thing’. The characterisation of this account apparently assumes no action at a temporal distance, an assumption that also underlies Earman’s account of determinism. In this paper I show that there is a way to define determinism that allows worlds with action at a temporal distance to count as deterministic, that action at a (...) temporal distance is possible on a best systems account of laws, and hence that Callender need not make this assumption.

The standard approach to the so-called paradoxes of identity has been to argue that these paradoxes do not essentially concern the notion of identity but rather betray misconceptions on our part regarding other metaphysical notions, like that of an object or a property. This paper proposes a different approach by pointing to an ambiguity in the identity predicate and arguing that the concept of identity that figures in many ordinary identity claims, including those that appear in the paradoxes, is not (...) the traditional philosophical concept but one that can be defined in terms of relevant similarity. This approach to the paradoxes will be argued to be superior to the standard one. (shrink)

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

We discuss abstraction principles in the context of modal and temporal logic. It is argued that abstractionism conflicts with both serious presentism and serious actualism.

The method of thought experiments or possible cases is widespread in philosophy and elsewhere. Thought experiments come with variegated theoretical commitments. These commitments are risky. They may turn out to be false or at least controversial. Other things being equal, it seems preferable to do with minimal commitments. I explore exemplary ways of minimising commitments, focusing on modal ones. There is a near-consensus to treat the scenarios considered in thought experiments as metaphysical possibilities. I challenge this consensus. Paradigmatic thought experiments (...) do not have to come with a commitment to metaphysical possibilities. In the first section, I point out difficulties with the prevailing focus on metaphysical possibilities. In the second section, I present alternative formalisations of a paradigmatic thought experiment, the Gettier experiment. Gettier’s words leave open the kind of possibilities under consideration. The standard way of spelling out Gettier’s argument uses metaphysical possibilities. One alternative proposal uses nomological possibilities. A second one uses epistemic possibilities. My modest conclusion: as long as it is not established that a thought experiment requires a commitment to metaphysical modality, one should avoid such a commitment. My preferred way of doing so is to replace the commitment to one particular formalisation by a commitment to a disjunction of alternative formalisations. (shrink)

I present an exemplary Humean modal epistemology. My version takes inspiration from but incurs no commitment to both Hume’s historical position and Lewis’s Humeanism. Modal epistemology should meet two challenges: the Integration challenge of integrating metaphysics and epistemology and the Reliability challenge of giving an account of how our epistemic capacities can be reliable in detecting modal truth. According to Lewis, modal reasoning starts from certain Humean principles: there is only the vast mosaic of spatiotemporally distributed local matters of fact. (...) The facts can be arbitarily recombined. These principles cannot be taken for granted. I suggest a bottom-up approach instead: Humean principles of recombining the mosaic of facts can be retrieved from the evolutionarily instilled and empirically informed use of imagination in exploring everyday circumstantial possibilities. This use of imagination conforms to a primitive conception of matter as freely recombinable. The modal beliefs that can be obtained from generalizing the more elementary exercise of imagination have to be corrected. Recombination is limited by sortal criteria of identity. Moreover, the overall picture of a recombinable spatiotemporal mosaic must be weighed against the results of science. (shrink)

Descriptivism in the ontology of art is the thesis that the correct ontological proposal for a kind of artwork cannot show the nascent ontological conception of such things embedded in our critical and appreciative practices to be substantially mistaken. Descriptivists believe that the kinds of revisionary art ontological proposals propounded by Nelson Goodman, Gregory Currie, Mark Sagoff, and me are methodologically misconceived. In this paper I examine the case that has been made for a local form of descriptivism in the (...) ontology of art: a form that does not quarrel with the possibility of revisionism in matters of ‘fundamental metaphysics’, but which argues that special features of the arts make descriptivism in this particular sphere obligatory. David Davies, Andrew Kania and Stephen Davies are local descriptivists in this sense. I argue that the burden of proof lies with the local descriptivist, but that this burden is too heavy for him to carry. Specifically, it emerges that the only way in which the local descriptivist can motivate his position is by arguing that our artistic practices determine the art ontological facts: a thesis that local descriptivists typically appeal to, but have not been able to argue for successfully. My conclusion is that the methodological debate in the ontology of art should now proceed by focussing on the case for global descriptivism: i.e. that form of descriptivism that opposes the possibility of revisionism in ontological matters across the board.

In certain philosophical quarters, a new metaphilosophical position is being discussed—antiphilosophy. Such a position seems to maintain that there is no distinction between philosophy and sophistry, reason and rhetoric, arguing and emoting. This paper examines antiphilosophy. Specifically, it aims to address three interrelated questions: Is antiphilosophy a possible metaphilosophical position? If it is, what characterizes it? And what ramifications would it have? The paper argues that antiphilosophy is possible and is best construed as an attempt to reconstruct philosophical discourse on (...) noncognitive lines. Explicitly, “to assert” and the belief propositional attitude is replaced by “to convince” and a pro‐attitude desire to rhetorically talk someone into something. The paper examines one possible form such a position could take as well as various ramifications of it. (shrink)

Realists about universals face a question about grounding. Are things how they are because they instantiate the universals they do? Or do they instantiate those universals because they are how they are? Take Ebenezer Scrooge. You can say that Scrooge is greedy because he instantiates greediness, or you can say that Scrooge instantiates greediness because he is greedy. I argue that there is reason to prefer the latter to the former. I develop two arguments for the view. I also respond (...) to some concerns one might have about the view defended. I close by showing that analogous views regarding the truth of propositions and the existence of facts are supported by analogs of one of these arguments. (shrink)

Maureen Donnelly’s (2016) relative positionalism correctly handles any fixed arity relation with any symmetry such a relation can have, yielding the intuitively correct way(s) in which that relation can apply. And it supplies an explanation of what is going on in the world that makes this the case. But it has at least one potential shortcoming — one that its opponents are likely to seize upon: it can only handle relations with fixed arities. It is unable to handle relations with (...) variable arities. I argue that, all else being equal, relative positionalism ought nonetheless to be preferred to its closest competitors — at least to the extent that the explanation it supplies of relational application is plausible — even though those competitors can handle variable arity relations in addition to fixed arity relations.

_ The Nature of Contingency _: _ Quantum Physics as Modal Realism _, by AlastairWilson. Oxford: Oxford University Press, 2020. Pp. xi + 219.

The modal primitivist who takes a sentential possibility operator as her only modal resource can provide adequate representations of the familiar concepts of weak, strong and global supervenience. The primitivist representations of these concepts can be applied to provide adequate interpretations of speciflc supervenience theses which will be considered. Moreover the modal primitivist is no better and no worse placed than the genuine modal realist to present supervenience as a simple and unifled notion. Therefore, Lewis is unjustified in claiming that (...) a genuine modal realist approach to the analysis of the concept of supervenience is superior to a modal primitivist approach. (shrink)

We propose a novel interpretation of Lewis on the analysis of modality that is constructed from primary sources, comprehensive and unprecedented. Our guiding precepts are to distinguish semantics from metaphysics, while respecting the inter-relations between them, and to discern whatever may be special, semantically or metaphysically, about the modal case. Following detailed presentation, we amplify and advocate our interpretation by providing a conforming genealogy of Lewis’s theory of modality and applying it to construct a detailed and newly illuminating version of (...) the Lewisian theory of modality de re.

Colin McGinn proposes that acceptance of the supervenience of the modal on the actual is the natural form of expression of a non-objectual realism about modality. Here, some of the difficulties that arise in applying theses of supervenience to the modal-actual case are discussed. It is then argued: 1)that the truth of many such theses is determined on uncontroversial modal logical and conceptual grounds, and 2) that this and other independent considerations render it highly implausible that the affirmation of modal-actual (...) supervenience amounts to a modal realism.

If a possible-worlds semantic theory for modal logics is pure, then the assertion of the theory, taken at face-value, can bring no commitment to the existence of a plurality of possible worlds (genuine or ersatz). But if we consider an applied theory (an application of the pure theory) in which the elements of the models are required to be possible worlds, then assertion of such a theory, taken at face-value, does appear to bring commitment to the existence of a plurality (...) of possible worlds. Or at least that is so if the applied theory is adequate. For an applied possible-worlds semantic theory that is constrained to contain only one-world models is bound to deliver results on validity, soundness and completeness that are apt to seem disastrous. I attempt to steer a course between commitment to the existence of a plurality of possible worlds and commitment to such a disastrous applied possible-worlds semantics by noting, and developing, the position of one who asserts such a theory at face-value but who remains agnostic about the existence of other (non-actualized) possible worlds. Thus, a novel interpretation of applied possible-worlds semantics is offered on which we may lay claim to whatever benefits such a theory offers while avoiding realism about (other) possible worlds. Thereby, the contention that applied possible-worlds semantics gives us reason to be realists about possible worlds is (further) undermined. (shrink)

In this reply, we defend our argument for the incompleteness of Genuine Modal Realism against Paseau's criticisms. Paseau claims that isomorphic set of worlds represent the same possibilities, but not only is this implausible, it is inimical to the target of our paper: Lewis's theory of possible worlds. We argue that neither Paseau's model-theoretic results nor his comparison to arithmetic carry over to GMR. We end by distinguishing two notions of incompleteness and urge that, for all that Paseau has said, (...) GMR remains incomplete in the relevant sense. (shrink)

There is a de re modal truth that proves inconvenient for the canonical Lewisian theory of modality. For this truth requires on that theory, the existence of things (counterparts) that exist in distinct worlds but are also spatiotemporally related.

The modal antirealist, as presented here, aims to secure at least some of the benefits associated with talking in genuine modal realist terms while avoiding commitment to a plurality of Lewisian (or ersatz) worlds. The antirealist stance of agnosticism about other worlds combines acceptance of Lewis's account of what world-talk means with refusal to assert, or believe in, the existence of other worlds. Agnosticism about other worlds does not entail a comprehensive agnosticism about modality, but where such agnosticism about modality (...) is enforced, the aim of the agnostic programme is to show that it is not detrimental to our modal practices. The agnostic programme consists in an attempt to demonstrate the rational dispensability of that disputed class of modal beliefs which the agnostic eschews, but which are held by the realist and the folk. Here I attempt to motivate, describe, and illustrate such an agnostic antirealist programme in modal philosophy. (shrink)

Lewis’ analysis of modality faces a problem in that it appears to confer unintended truth values to certain modal claims about the pluriverse: e.g. ‘It is possible that there are many worlds’ is false when we expect truth. This is the problem of advanced modalizing. Divers presents a principled solution to this problem by treating modal modifiers as semantically redundant in some such cases. However, this semantic move does not deal adequately with advanced de re modal claims. Here, we motivate (...) and detail a comprehensive semantics for advanced modalizing de dicto and de re. The generalized semantic feature of the initial solution is not redundancy but absence from counterpart-theoretic translations of world-constrictions. (shrink)

We outline a theory of the cognitive role of belief in absolute necessity that is normative and intended to be metaphysically neutral. We take this theory to be unique in scope since it addresses simultaneously the questions of how such belief is (properly) acquired and of how it is (properly) manifest. The acquisition and manifestation conditions for belief in absolute necessity are given univocally, in terms of complex higher-order attitudes involving two distinct kinds of supposition (A-supposing and C-supposing). It is (...) subsequently argued that the proposed acquisition and manifestation conditions are rationally interdependent, and that such harmony affords explanations of connections between different facets of belief in necessity that otherwise remain mysterious.

According to anti-individualism, the basic building blocks of the world are not individuals. The anti-individualist argues that standard, individual-entailing claims–for instance, that Theia is a cat–are mistaken in presupposing that there are individuals, but that such claims correspond to statements in a feature-placing language devoid of these presuppositions. Instead, the world is entirely made up of non-individualistic features–structurally akin to familiar examples such as it's raining or it's snowing–that are arranged in particular ways. Since features do not carve out individual (...) differences, however, this seems to entail that there is a class of statements in an individualistic language–statements expressing mere differences in which object is which–the members of which all correspond to the same anti-individualist description. That is, anti-individualism seems to entail anti-haecceitism, according to which all differences in ways the world could be supervene on qualitative differences. In this paper, I argue that, on the contrary, the anti-individualist has the resources to accommodate non-qualitative differences among ways the world could be. Moreover, haecceitistic anti-individualism does justice to the motivations for rejecting individuals while nevertheless accommodating intuitions that certain kinds of scenarios are metaphysically distinct.

John MacFarlane has recently presented a novel argument in support of truth- relativism. According to this, contextualists fail to accommodate retrospective reassessments of propositional contents, when it comes to languages which are rich enough to express actuality. The aim of this note is twofold. First, it is to argue that the argument can be effectively rejected, since it rests on an inadequate conception of actuality. Second, it is to offer a more plausible account of actuality in branching time, along the (...) line of Lewis (1970/1983). (shrink)
