85Between scientism and abstractionism in the metaphysics of emergenceIn Sophie Gibb, Robin Findlay Hendry & Tom Lancaster (eds.), The Routledge Handbook of Philosophy of Emergence, Routledge. pp. 157-176. 2018.I discuss certain representative accounts of metaphysical emergence falling into three broad categories, assessing their prospects for satisfying certain criteria; the ensuing dialectic has a bit of the Goldilocks fable about it. At one end of the spectrum are what I call ‘scientistic’ accounts, which characterize metaphysical emergence by appeal to one or another specific feature commonly registered in scientific descriptions of seeming cases of emergence; such accounts, I argue, typically fail…Read more

19Three Barriers to Philosophical ProgressIn Russell Blackford & Damien Broderick (eds.), Philosophy's Future, Wiley. 2017-04-27.I argue that the best explanation of the multiplicity of available frameworks for treating any given philosophical topic is that philosophy currently (though not insuperably) lacks fixed standards; I then go on to identify three barriers to philosophical progress associated with our present epistemic situation. First is that the lack of fixed standards encourages what I call “intra‐disciplinary siloing,” and associated dialectical and argumentative failings; second is that the lack of fixed stan…Read more

353Metaphysical indeterminacy in the multiverseIn Valia Allori (ed.), Quantum Mechanics and Fundamentality: Naturalizing Quantum Theory between Scientific Realism and Ontological Indeterminacy, Springer. pp. 375-395. 2022.One might suppose that Everettian quantum mechanics (EQM) is inhospitable to metaphysial indeterminacy (MI), given that, as A. Wilson (2020) puts it, "the central idea of EQM is to replace indeterminacy with multiplicity" (77). But as Wilson goes on to suggest, the popular decoherence-based understanding of EQM (henceforth: DEQM) appears to admit of indeterminacy in both world number and world nature, where the latter indeterminacy---our focus here---is plausibly metaphysical. After a brief pres…Read more

16Hume's Dictum and Metaphysical ModalityIn Barry Loewer & Jonathan Schaffer (eds.), A Companion to David Lewis, Wiley. 2015.Many contemporary philosophers accept a strong generalization of Hume's denial of necessary causal connections, in the form of Hume's dictum (HD), according to which there are no metaphysically necessary connections between distinct, intrinsically typed entities. Hume's version of his dictum occurs during his investigation into the source of the idea of causal connection. The most powerful role that HD plays in Lewis's system concerns its providing a basis for, as Lewis puts it, a "principle of …Read more

399How superduper does a physicalist supervenience need to be?Philosophical Quarterly 49 (194): 33-52. 1999.Note: this is the first published presentation and defense of the 'proper subset strategy' for making sense of non-reductive physicalism or the associated notion of realization; this is sometimes, inaccurately, called "Shoemaker's subset strategy"; if people could either call it the 'subset strategy' or better yet, add my name to the mix I would appreciate it. Horgan claims that physicalism requires "superdupervenience" -- supervenience plus robust ontological explanation of the supervenient in…Read more

97On the Notion of Diachronic EmergenceIn Amanda Bryant & David Yates (eds.), Rethinking Emergence, Oxford University Press. forthcoming.Is there a need for a distinctively diachronic conception of metaphysical emergence? Here I argue to the contrary. In the main, my strategy consists in considering a representative sample of accounts of purportedly diachronic metaphysical emergence, and arguing that in each case, the purportedly diachronic emergence at issue either can (and should) be subsumed under a broadly synchronic account of metaphysical emergence, or else is better seen as simply a case of causation. In addition, I consid…Read more

369Relativized metaphysical modalityIn Dean W. Zimmerman (ed.), Oxford Studies in Metaphysics, Oxford University Press. pp. 189-226. 2008.It is commonly supposed that metaphysical modal claims are to be evaluated with respect to a single domain of possible worlds: a claim is metaphysically necessary just in case it is true in every possible world, and metaphysically possible just in case it is true in some possible world. We argue that the standard understanding is incorrect; rather, whether a given claim is metaphysically necessary or possible is relative to which world is indicatively actual. We motivate our view by attention to…Read more

138Does anti-exceptionalism about logic entail that logic is a posteriori?Synthese 200 (3): 1-17. 2022.The debate between exceptionalists and anti-exceptionalists about logic is often framed as concerning whether the justification of logical theories is a priori or a posteriori (for short: whether logic is a priori or a posteriori). As we substantiate (S1), this framing more deeply encodes the usual anti-exceptionalist thesis that logical theories, like scientific theories, are abductively justified, coupled with the common supposition that abduction is an a posteriori mode of inference, in the s…Read more

852In defense of CountabilismPhilosophical Studies 179 (7): 2199-2236. 2022.Inspired by Cantor's Theorem (CT), orthodoxy takes infinities to come in different sizes. The orthodox view has had enormous influence in mathematics, philosophy, and science. We will defend the contrary view---Countablism---according to which, necessarily, every infinite collection (set or plurality) is countable. We first argue that the potentialist or modal strategy for treating Russell's Paradox, first proposed by Parsons (2000) and developed by Linnebo (2010, 2013) and Linnebo and Shapiro (…Read more

169Quantum indeterminacy and the double-slit experimentPhilosophical Studies 178 (10): 3291-3317. 2021.In Calosi and Wilson (Phil Studies 2019/2018), we argue that on many interpretations of quantum mechanics (QM), there is quantum mechanical indeterminacy (QMI), and that a determinable-based account of metaphysical indeterminacy (MI), as per Wilson 2013 and 2016, properly accommodates the full range of cases of QMI. Here we argue that this approach is superior to other treatments of QMI on offer, both realistic and deflationary, in providing the basis for an intelligible explanation of the inter…Read more

252Relativized metaphysical modality: Index and contextIn Otávio Bueno & Scott A. Shalkowski (eds.), The Routledge Handbook of Modality, Routledge. 2018.Relativized Metaphysical Modality (RMM: Murray and Wilson, 'Relativized metaphysical modality', Oxford Studies in Metaphysics, 2012; Murray, Perspectives on Modal Metaphysics, 2017) exploits 'two-dimensionalist' resources to metaphysical, rather than epistemological, ends: the second dimension offers perspective-dependence without contingency, diverting attacks on 'Classical' analyses of modals (in effect, analyses validating S5 and the Barcan Formulae). Here, we extend the RMM program in two di…Read more

387Grounding-based formulations of physicalismTopoi 37 (3): 495-512. 2016.I problematize Grounding-based formulations of physicalism. More specifically, I argue, first, that motivations for adopting a Grounding-based formulation of physicalism are unsound; second, that a Grounding-based formulation lacks illuminating content, and that attempts to imbue Grounding with content by taking it to be a strict partial order are unuseful and problematic ; third, that conceptions of Grounding as constitutively connected to metaphysical explanation conflate metaphysics and epist…Read more

166On Mary Shepherd's Essay upon the Relation of Cause and EffectIn Eric Schliesser (ed.), Neglected Classics of Philosophy, Volume 2, Oxford University Press. 2022.Mary Shepherd (1777–1847) was a fierce and brilliant critic of Berkeley and Hume, who moreover offered strikingly original positive views about the nature of reality and our access to it which deserve much more attention (and credit, since she anticipates many prominent views) than they have received thus far. By way of illustration, I focus on Shepherd's 1824 Essay Upon the Relation of Cause and Effect, Controverting the Doctrine of Mr. Hume, Concerning the Nature of that Relation (ERCE). After…Read more

97Review of Physicalism Deconstructed: Levels of Reality and the Mind-Body Problem, by Kevin Morris (review)Notre Dame Philosophical Reviews 1. 2020.Morris’s book is a valuable contribution. For the reasons below, I don’t think his case against NRP succeeds, and his version of EP faces a serious difficulty. Even so, this is an admirably clear, subtle, and well-informed brief, and philosophers interested in the structure of natural reality have much to gain from Morris’s insightful discussion and argumentation.

177Metaphysical EmergenceOxford University Press. 2021.Both the special sciences and ordinary experience suggest that there are metaphysically emergent entities and features: macroscopic goings-on (including mountains, trees, humans, and sculptures, and their characteristic properties) which depend on, yet are distinct from and distinctively efficacious with respect to, lower-level physical configurations and features. These appearances give rise to two key questions. First, what is metaphysical emergence, more precisely? Second, is there any metaph…Read more

315Review of Tropes, by Douglas Ehring (review)Mind 131 (521): 369-379. 2022.Tropes is a systematic investigation into the metaphysics of properties, aiming to motivate and defend trope theory, and more specifically Natural Class Trope Nominalism (NCTN). Ehring’s book treats an impressive span of relevant positions, considerations, debates and objections with charity and clarity; it’s also a real page-turner, at least if one has (as I do) a taste for analytic twists and turns.

95Correction to: Grounding-Based Formulations of PhysicalismTopoi 38 (1): 261-261. 2019.This correction reflects that I forgot to cite Stephan Leuenberger's unpublished work in the paragraph beginning "More promising, perhaps, is the orthodox view ..." in Section 5. The overall argument of Section 5 is a development of an argument I gave in footnote 27 of 'No Work for a Theory of Grounding' (Inquiry, 2014). At issue in the relevant sections of 'No Work...' and 'Grounding-based Formulations...' is whether a proponent of Grounding has resources to accommodate strongly emergent phenom…Read more

181Abduction versus conceiving in modal epistemologySynthese 198 (Suppl 8): 2045-2076. 2019.How should modal reasoning proceed? Here we compare abduction-based and conceiving-based modal epistemologies, and argue that an abduction-based approach is preferable, and by a wide margin.

472A determinable-based account of metaphysical indeterminacyInquiry: An Interdisciplinary Journal of Philosophy 56 (4): 359-385. 2013.ABSTRACT Many phenomena appear to be indeterminate, including material macro-object boundaries and certain open future claims. Here I provide an account of indeterminacy in metaphysical, rather than semantic or epistemic, terms. Previous accounts of metaphysical indeterminacy have typically taken this to involve its being indeterminate which of various determinate states of affairs obtain. On my alternative account, MI involves its being determinate that an indeterminate state of affairs obtains…Read more

2490No Work for a Theory of GroundingInquiry: An Interdisciplinary Journal of Philosophy 57 (5-6): 535-579. 2014.It has recently been suggested that a distinctive metaphysical relation— ‘Grounding’—is ultimately at issue in contexts in which some goings-on are said to hold ‘in virtue of’’, be ‘metaphysically dependent on’, or be ‘nothing over and above’ some others. Grounding is supposed to do good work in illuminating metaphysical dependence. I argue that Grounding is also unsuited to do this work. To start, Grounding alone cannot do this work, for bare claims of Grounding leave open such basic questions …Read more

293Quantum metaphysical indeterminacyPhilosophical Studies 176 (10). 2019.On many currently live interpretations, quantum mechanics violates the classical supposition of value definiteness, according to which the properties of a given particle or system have precise values at all times. Here we consider whether either metaphysical supervaluationist or determinable-based approaches to metaphysical indeterminacy can accommodate quantum metaphysical indeterminacy (QMI). We start by discussing the standard theoretical indicator of QMI, and distinguishing three seemingly …Read more

234Three Barriers to Philosophical ProgressIn Russell Blackford & Damien Broderick (eds.), Philosophy's Future: The Problem of Philosophical Progress, Wiley-blackwell. pp. 91--104. 2017.I argue that the present (if not insuperable) lack of fixed standards in philosophy is associated with three barriers to philosophical progress, pertaining to intra-disciplinary siloing, sociological rather than philosophical determinants of philosophical attention, and the encouraging of bias.

276Must strong emergence collapse?Philosophica 91 (1): 49--104. 2017.Some claim that the notion of strong emergence as involving ontological or causal novelty makes no sense, on grounds that any purportedly strongly emergent features or associated powers 'collapse', one way or another, into the lower-level base features upon which they depend. Here we argue that there are several independently motivated and defensible means of preventing the collapse of strongly emergent features or powers into their lower-level bases, as directed against a conception of strongly…Read more

555Fundamental determinablesPhilosophers' Imprint 12. 2012.Contemporary philosophers commonly suppose that any fundamental entities there may be are maximally determinate. More generally, they commonly suppose that, whether or not there are fundamental entities, any determinable entities there may be are grounded in, hence less fundamental than, more determinate entities. So, for example, Armstrong takes the physical objects constituting the presumed fundamental base to be “determinate in all respects” (1961, 59), and Lewis takes the properties characte…Read more

380The unity and priority arguments for GroundingIn Ken Aizawa & Carl Gillett (eds.), Scientific Composition and Metaphysical Ground, Palgrave-macmillan. pp. 171-204. 2016.Grounding, understood as a primitive posit operative in contexts where metaphysical dependence is at issue, is not able on its own to do any substantive work in characterizing or illuminating metaphysical dependence---or so I argue in 'No Work for a Theory of Grounding' (Inquiry, 2014). Such illumination rather requires appeal to specific metaphysical relations---type or token identity, functional realization, the determinable-determinate relation, the mereological part-whole relation, and so o…Read more

453Essence and dependenceIn Mircea Dumitru (ed.), Metaphysics, Meaning, and Modality: Themes from Kit Fine, Oxford University Press. pp. 283-300. 2020.I first discuss Kit Fine's distinctive 'schema-based' approach to metaphysical theorizing, which aims to identify general principles accommodating any intelligible application of the notion(s), by attention to his accounts of essence and dependence. I then raise some specific concerns about the general principles Fine takes to schematically characterize these notions. In particular, I present various counterexamples to Fine's essence-based account of ontological dependence. The problem, roughly…Read more
