    On what grounds what
    In David Manley, David J. Chalmers & Ryan Wasserman (eds.), Metametaphysics: New Essays on the Foundations of Ontology, Oxford University Press. pp. 347-383. 2009.
    On the now dominant Quinean view, metaphysics is about what there is. Metaphysics so conceived is concerned with such questions as whether properties exist, whether meanings exist, and whether numbers exist. I will argue for the revival of a more traditional Aristotelian view, on which metaphysics is about what grounds what. Metaphysics so revived does not bother asking whether properties, meanings, and numbers exist (of course they do!) The question is whether or not they are fundamental.

    Monism: The Priority of the Whole
    Philosophical Review 119 (1): 31-76. 2010.
    Consider a circle and a pair of its semicircles. Which is prior, the whole or its parts? Are the semicircles dependent abstractions from their whole, or is the circle a derivative construction from its parts? Now in place of the circle consider the entire cosmos (the ultimate concrete whole), and in place of the pair of semicircles consider the myriad particles (the ultimate concrete parts). Which if either is ultimately prior, the one ultimate whole or its many ultimate parts?

    Knowledge entails dispositional belief
    with David Rose
    Philosophical Studies 166 (S1): 19-50. 2013.
    Knowledge is widely thought to entail belief. But Radford has claimed to offer a counterexample: the case of the unconfident examinee. And Myers-Schulz and Schwitzgebel have claimed empirical vindication of Radford. We argue, in defense of orthodoxy, that the unconfident examinee does indeed have belief, in the epistemically relevant sense of dispositional belief. We buttress this with empirical results showing that when the dispositional conception of belief is specifically elicited, people’s i…Read more

    Contrastive Knowledge Surveyed
    Noûs 46 (4): 675-708. 2010.
    Suppose that Ann says, “Keith knows that the bank will be open tomorrow.” Her audience may well agree. Her knowledge ascription may seem true. But now suppose that Ben—in a different context—also says “Keith knows that the bank will be open tomorrow.” His audience may well disagree. His knowledge ascription may seem false. Indeed, a number of philosophers have claimed that people’s intuitions about knowledge ascriptions are context sensitive, in the sense that the very same knowledge ascription …Read more

    Folk teleology drives persistence judgments
    Synthese 197 (12): 5491-5509. 2020.
    Two separate research programs have revealed two different factors that feature in our judgments of whether some entity persists. One program—inspired by Knobe—has found that normative considerations affect persistence judgments. For instance, people are more inclined to view a thing as persisting when the changes it undergoes lead to improvements. The other program—inspired by Kelemen—has found that teleological considerations affect persistence judgments. For instance, people are more inclined…Read more

    Contrastive causation
    Philosophical Review 114 (3): 327-358. 2005.
    Causation is widely assumed to be a binary relation: c causes e. I will argue that causation is a quaternary, contrastive relation: c rather than C* causes e rather than E*, where C* and E* are nonempty sets of contrast events. Or at least, I will argue that treating causation as contrastive helps resolve some paradoxes.

    Grounding in the image of causation
    Philosophical Studies 173 (1): 49-100. 2016.
    Grounding is often glossed as metaphysical causation, yet no current theory of grounding looks remotely like a plausible treatment of causation. I propose to take the analogy between grounding and causation seriously, by providing an account of grounding in the image of causation, on the template of structural equation models for causation

    The deflationary metaontology of Thomasson's ordinary objects
    Philosophical Books 50 (3): 142-157. 2009.
    In Ordinary Objects, Thomasson pursues an integrated conception of ontology and metaontology. In ontology, she defends the existence of shoes, ships, and other ordinary objects. In metaontology, she defends a deflationary view of ontological inquiry, designed to suck the air out of arguments against ordinary objects. The result is an elegant and insightful defense of a common sense worldview. I am sympathetic—in spirit if not always in letter—with Thomasson’s ontology. But I am skeptical of her …Read more

    Is there a fundamental level?
    Noûs 37 (3). 2003.

    The Internal Relatedness of All Things
    Mind 119 (474): 341-376. 2010.
    The argument from internal relatedness was one of the major nineteenth century neo-Hegelian arguments for monism. This argument has been misunderstood, and may even be sound. The argument, as I reconstruct it, proceeds in two stages: first, it is argued that all things are internally related in ways that render them interdependent; second, the substantial unity of the whole universe is inferred from the interdependence of all of its parts. The guiding idea behind the argument is that failure of …Read more

    Contrastive knowledge
    In Tamar Szabó Gendler & John Hawthorne (eds.), Oxford Studies in Epistemology, Oxford University Press. pp. 235. 2005.
    Does G. E. Moore know that he has hands? Yes, says the dogmatist: Moore’s hands are right before his eyes. No, says the skeptic: for all Moore knows he could be a brain-in-a-vat. Yes and no, says the contrastivist: yes, Moore knows that he has hands rather than stumps; but no, Moore does not know that he has hands rather than vat-images of hands. The dogmatist and the skeptic suppose that knowledge is a binary, categorical relation: s knows that p. The contrastivist says that knowledge is a tern…Read more

    Folk Mereology is Teleological
    with David Rose
    Noûs 51 (2): 238-270. 2017.
    When do the folk think that mereological composition occurs? Many metaphysicians have wanted a view of composition that fits with folk intuitions, and yet there has been little agreement about what the folk intuit. We aim to put the tools of experimental philosophy to constructive use. Our studies suggest that folk mereology is teleological: people tend to intuit that composition occurs when the result serves a purpose. We thus conclude that metaphysicians should dismiss folk intuitions, as tie…Read more

    Spacetime the one substance
    Philosophical Studies 145 (1). 2009.
    What is the relation between material objects and spacetime regions? Supposing that spacetime regions are one sort of substance, there remains the question of whether or not material objects are a second sort of substance. This is the question of dualistic versus monistic substantivalism. I will defend the monistic view. In particular, I will maintain that material objects should be identified with spacetime regions. There is the spacetime manifold, and the fundamental properties are pinned dire…Read more

    According to a prominent claim in recent epistemology, people are less likely to ascribe knowledge to a high stakes subject for whom the practical consequences of error are severe, than to a low stakes subject for whom the practical consequences of error are slight. We offer an opinionated "state of the art" on experimental research about the role of stakes in knowledge judgments. We draw on a first wave of empirical studies--due to Feltz & Zarpentine (2010), May et al (2010), and Buckwalter (2…Read more

    The least discerning and most promiscuous truthmaker
    Philosophical Quarterly 60 (239). 2010.
    I argue that the one and only truthmaker is the world. This view can be seen as arisingfrom (i) the view that truthmaking is a relation of grounding holding between true propositions and fundamental entities, together with (ii) the view that the world is the one and only fundamental entity. I argue that this view provides an elegant and economical account of the truthmakers, while solving the problem of negative existentials, in a way that proves ontologically revealing

    David Lewis’s semantics for counterfactuals remains the standard view. Yet counter-examples have emerged, which suggest a need to invoke causal independence, and thus threaten conceptual circularity. I will review some of these counter-examples (§§1–2), illustrate how causal independence proves useful (§3), and suggest that any resulting circularity is unproblematic (§4).

    From nihilism to monism
    Australasian Journal of Philosophy 85 (2). 2007.
    Mereological nihilism is the view that all concrete objects are simple. Existence monism is the view that the only concrete object is one big simple: the world. I will argue that nihilism culminates in monism. The nihilist demands the simplest sufficient ontology, and the monist delivers it

    From contextualism to contrastivism
    Philosophical Studies 119 (1-2): 73-104. 2004.
    Contextualism treats ‘knows’ as an indexical that denotes different epistemic properties in different contexts. Contrastivism treats ‘knows’ as denoting a ternary relation with a slot for a contrast proposition. I will argue that contrastivism resolves the main philosophical problems of contextualism, by employing a better linguistic model. Contextualist insights are best understood by contrastivist theory.

    Trumping preemption
    Journal of Philosophy 97 (4): 165-181. 2000.
    Extant counterfactual accounts of causation (CACs) still cannot handle preemptive causation. I describe a new variety of preemption, defend its possibility, and use it to show the inadequacy of extant CACs. Imagine that it is a law of nature that the first spell cast on a given day match the enchantment that midnight.

    Review: Andreas Hüttemann: what's wrong with microphysicalism? (review)
    British Journal for the Philosophy of Science 59 (2): 253-257. 2008.
    In What’s Wrong With Microphysicalism?, Andreas H üttemann argues against the ontological priority of the microphysical, in favour of a ‘pluralism’ that accepts physical systems of all scales as interdependent equals. This is thoughtful and original work, deploying an understanding of the relevant physics to mount a serious challenge to the dominant microphysicalist view.

    Causation by disconnection
    Philosophy of Science 67 (2): 285-300. 2000.
    The physical and/or intrinsic connection approach to causation has become prominent in the recent literature, with Salmon, Dowe, Menzies, and Armstrong among its leading proponents. I show that there is a type of causation, causation by disconnection, with no physical or intrinsic connection between cause and effect. Only Hume-style conditions approaches and hybrid conditions-connections approaches appear to be able to handle causation by disconnection. Some Hume-style, extrinsic, absence-relati…Read more

    Disconnection and Responsibility
    Legal Theory 18 (4): 399-435. 2012.
    Michael Moore’s Causation and Responsibility offers an integrated conception of the law, morality, and metaphysics, centered on the notion of causation, grounded in a detailed knowledge of case law, and supported on every point by cogent argument. This is outstanding work. It is a worthy successor to Harte and Honoré’s classic Causation in the Law, and I expect that it will guide discussion for many years to come.

    Two Conceptions of Sparse Properties
    Pacific Philosophical Quarterly 85 (1). 2004.
    Are the sparse properties drawn from all the levels of nature, or only the fundamental level? I discuss the notion of sparse property found in Armstrong and Lewis, show that there are tensions in the roles they have assigned the sparse properties, and argue that the sparse properties should be drawn from all the levels of nature.

    Knowing the Answer
    Philosophy and Phenomenological Research 75 (2): 383-403. 2007.
    How should one understand knowledge-wh ascriptions? That is, how should one understand claims such as ‘‘I know where the car is parked,’’ which feature an interrogative complement? The received view is that knowledge-wh reduces to knowledge that p, where p happens to be the answer to the question Q denoted by the wh-clause. I will argue that knowledge-wh includes the question—to know-wh is to know that p, as the answer to Q. I will then argue that knowledge-that includes a contextually implicit …Read more

    Epistemic comparativism: a contextualist semantics for knowledge ascriptions
    with Zoltán Gendler Szabó
    Philosophical Studies 168 (2): 491-543. 2014.
    Knowledge ascriptions seem context sensitive. Yet it is widely thought that epistemic contextualism does not have a plausible semantic implementation. We aim to overcome this concern by articulating and defending an explicit contextualist semantics for ‘know,’ which integrates a fairly orthodox contextualist conception of knowledge as the elimination of the relevant alternatives, with a fairly orthodox “Amherst” semantics for A-quantification over a contextually variable domain of situations. Wh…Read more

    The irrelevance of the subject: Against subject-sensitive invariantism
    Philosophical Studies 127 (1): 87-107. 2006.
    Does what you know depend on what is at stake for you? That is, is the knowledge relation sensitive to the subject’s practical interests? Subject sensitive invariantists (Fantl and McGrath, 2002; Hawthorne, 2004, ch. 4; Stanley, forthcoming) say that the answer is yes. They claim to capture the contextualist data without the shifty semantics. I will argue that the answer is no. The knowledge relation is sensitive to what is in question for the attributor, rather than what is at stake for the sub…Read more

    Skepticism, Contextualism, and Discrimination

    The skeptic says that “knowledge” is an absolute term, whereas the contextualist says that ‘knowledge” is a relationally absolute term. Which is the better hypothesis about “knowledge”? And what implications do these hypotheses about “knowledge” have for knowledge? I argue that the skeptic has the better hypothesis about “knowledge”, but that both hypotheses about “knowledge” have deeply anti‐skeptical implications for knowledge, since both presuppose our capacity for epistemically salient discr…Read more

    Monism
    Stanford Encyclopedia of Philosophy. 2008.
    This entry focuses on two of the more historically important monisms: existence monism and priority monism . Existence monism targets concrete objects and counts by tokens. This is the doctrine that exactly one concrete object exists. Priority monism also targets concrete objects, but counts by basic tokens. This is the doctrine that exactly one concrete object is basic, which will turn out to be the classical doctrine that the whole is prior to its parts.
