    Fictionalism, Indifferentism, and Easy Ontology
    Festschrift for Matti Eklund. 2024.
    Fictionalism is supposed to be motivated, at least in part, by its ability to undermine our ordinary grounds for believing in numbers and other contested entities. Eklund argues that a weaker and less controversial view, which he calls indifferentism, can do the job just as effectively. I will show that whether he’s right about this depends upon how we think about “our ordinary grounds”. If we think about our ordinary grounds as consisting in what people are pre-theoretically inclined to say or …Read more

    Modal Security and Evolutionary Debunking
    Midwest Studies in Philosophy 47 135-156. 2023.
    According to principles of modal security, evidence undermines a belief only when it calls into question certain purportedly important modal connections between one’s beliefs and the truth (e.g., safety or sensitivity). Justin Clarke-Doane and Dan Baras have advanced such principles with the aim of blocking evolutionary moral debunking arguments. We examine a variety of different principles of modal security, showing that some of these are too strong, failing to accommodate clear cases of underm…Read more

    Mountains and Their Boundaries
    In Miguel Garcia-Godinez (ed.), Thomasson on Ontology, Springer Verlag. pp. 243-264. 2023.
    I examine Amie Thomasson’s account of the metaphysics of mountains and their boundaries, from her “Geographic Objects and the Science of Geography.” I begin by laying out a puzzle about mountains that generates some pressure towards accepting that we are somehow responsible for their having the boundaries that they do. As a foil for Thomasson’s own account, I present two competing theories of geographic objects—one on which they are thoroughly mind-dependent, and one on which they are thoroughly…Read more

    What Do the Folk Think about Composition and Does it Matter?
    In David Rose (ed.), Experimental Metaphysics, Bloomsbury Academic. pp. 187-206. 2017.
    Rose and Schaffer (forthcoming) argue that teleological thinking has a substantial influence on folk intuitions about composition. They take this to show (i) that we should not rely on folk intuitions about composition and (ii) that we therefore should not reject theories of composition on the basis of intuitions about composition. We cast doubt on the teleological interpretation of folk judgments about composition; we show how their debunking argument can be resisted, even on the assumption tha…Read more

    Composition
    Oxford Handbooks Online. 2016.
    When some objects are the parts of another object, they compose that object and that object is composite. This article is intended as an introduction to the central questions about composition and a highly selective overview of various answers to those questions. In §1, we review some formal features of parthood that are important for understanding the nature of composition. In §2, we consider some answers to the question: which pluralities of objects together compose something? As we will see, …Read more

    Conceptualism is the thesis that, for any perceptual experience E, (i) E has a Fregean proposition as its content and (ii) a subject of E must possess a concept for each item represented by E. We advance a framework within which conceptualism may be defended against its most serious objections (e.g., Richard Heck's argument from nonveridical experience). The framework is of independent interest for the philosophy of mind and epistemology given its implications for debates regarding transparency,…Read more

    Kripke maintains that one who stipulatively introduces the term ' one meter' as a rigid designator for the length of a certain stick s at time t is in a position to know a priori that if s exists at t then the length of s at t is one meter. Some (e.g., Soames 2003) have objected to this alleged instance of the contingent a priori on the grounds that the stipulator's knowledge would have to be based in part on substantive metalinguistic knowledge. I examine Soames's argument for the a posteriorit…Read more

    Unrestricted Composition and Restricted Quantification
    Philosophical Studies 140 (3): 319-334. 2008.
    Many of those who accept the universalist thesis that mereological composition is unrestricted also maintain that the folk typically restrict their quantifiers in such a way as to exclude strange fusions when they say things that appear to conflict with universalism. Despite its prima facie implausibility, there are powerful arguments for universalism. By contrast, there is remarkably little evidence for the thesis that strange fusions are excluded from the ordinary domain of quantification. Fur…Read more

    An Explanationist Account of Genealogical Defeat
    Philosophy and Phenomenological Research 106 (1): 176-195. 2023.
    Sometimes, learning about the origins of a belief can make it irrational to continue to hold that belief—a phenomenon we call ‘genealogical defeat’. According to explanationist accounts, genealogical defeat occurs when one learns that there is no appropriate explanatory connection between one’s belief and the truth. Flatfooted versions of explanationism have been widely and rightly rejected on the grounds that they would disallow beliefs about the future and other inductively-formed beliefs. Aft…Read more

    You see a cherry and you experience it as red. A textbook explanation for why you have this sort of experience is going to cite such things as the cherry’s chemical surface properties and the distinctive mixture wavelengths of light it is disposed to reflect. What does not show up in this explanation is the redness of the cherry. Many allege that the availability of color-free explanations of color experience somehow calls into question our beliefs about the colors of objects around us. We explo…Read more

    Conservatism, Counterexamples and Debunking
    Analysis 80 (3): 558-574. 2020.
    A symposium on my *Objects: Nothing Out of the Ordinary* (2015). In response to Wallace, I attempt to clarify the dialectical and epistemic role that my arguments from counterexamples were meant to play, I provide a limited defense of the comparison to the Gettier examples, and I embrace the comparison to Moorean anti-skeptical arguments. In response to deRosset, I provide a clearer formulation of conservatism, explain how a conservative should think about the interaction between intuition and s…Read more

    Debunking material induction
    Studies in History and Philosophy of Science Part A 84 20-27. 2020.
    We present an explanatory objection to Norton's material theory of induction, as applied to predictive inferences. According to the objection we present, there is an explanatory disconnect between our beliefs about the future and the relevant future facts. We argue that if we recognize such a disconnect, we are no longer rationally entitled to our future beliefs.

    Our aim here is to explore the prospects of a relativist response to moral debunking arguments. We begin by clarifying the relativist thesis under consideration, and we explain why relativists seem well-positioned to resist the arguments in a way that avoids the drawbacks of existing responses. We then show that appearances are deceiving. At bottom, the relativist response is no less question-begging than standard realist responses, and – when we turn our attention to the strongest formulation o…Read more

    Debunking arguments
    Philosophy Compass 14 (12). 2019.
    Debunking arguments—also known as etiological arguments, genealogical arguments, access problems, isolation objec- tions, and reliability challenges—arise in philosophical debates about a diverse range of topics, including causation, chance, color, consciousness, epistemic reasons, free will, grounding, laws of nature, logic, mathematics, modality, morality, natural kinds, ordinary objects, religion, and time. What unifies the arguments is the transition from a premise about what does or doesn't…Read more

    Form, Matter, Substance (review)
    Notre Dame Philosophical Reviews. 2019.
    In Form, Matter, Substance, Kathrin Koslicki articulates and defends her preferred brand of hylomorphism, weighing in on how we should conceive of the matter and the form of such compounds, and on how they can qualify as fundamental “substances” despite being ontologically dependent on their components. I review Koslicki’s principal claims and conclusions (§1), and then raise some concerns about her master argument for “individual forms” (§2) and her criticism of standard essentialist accounts o…Read more

    The Metaphysics of Establishments
    Australasian Journal of Philosophy 98 (3): 434-448. 2020.
    I present two puzzles about the metaphysics of stores, restaurants, and other such establishments. I defend a solution to the puzzles, according to which establishments are not material objects and are not constituted by the buildings that they occupy.

    Why Care About What There Is?
    Mind. forthcoming.
    There’s the question of what there is, and then there’s the question of what ultimately exists. Many contend that, once we have this distinction clearly in mind, we can see that there is no sensible debate to be had about whether there are such things as properties or tables or numbers, and that the only ontological question worth debating is whether such things are ultimate (in one or another sense). I argue that this is a mistake. Taking debates about ordinary objects as a case study, I show t…Read more

    Easy Ontology without Deflationary Metaontology
    Philosophy and Phenomenological Research 99 (1): 236-243. 2019.
    This is a contribution to a symposium on Amie Thomasson’s Ontology Made Easy (2015). Thomasson defends two deflationary theses: that philosophical questions about the existence of numbers, tables, properties, and other disputed entities can all easily be answered, and that there is something wrong with prolonged debates about whether such objects exist. I argue that the first thesis (properly understood) does not by itself entail the second. Rather, the case for deflationary metaontology rests l…Read more

    The Failure of Trust-Based Retributivism
    Law and Philosophy 22 (6): 561-575. 2003.
    Punishment stands in need of justification because it involves intentionally harming offenders. Trust-based retributivists attempt to justify punishment by appeal to the offender’s violation of the victim’s trust, maintaining that the state is entitled to punish offenders as a means of restoring conditions of trust to their pre-offense levels. I argue that trust-based retributivism fails on two counts. First, it entails the permissibility of punishing the legally innocent and fails to justify th…Read more

    Against Minimalist Responses to Moral Debunking Arguments
    Oxford Studies in Metaethics 15 309-332. 2020.
    Moral debunking arguments are meant to show that, by realist lights, moral beliefs are not explained by moral facts, which in turn is meant to show that they lack some significant counterfactual connection to the moral facts (e.g., safety, sensitivity, reliability). The dominant, “minimalist” response to the arguments—sometimes defended under the heading of “third-factors” or “pre-established harmonies”—involves affirming that moral beliefs enjoy the relevant counterfactual connection while gra…Read more

    Defining Textual Entailment
    with Eric Mack, Jacob Jett, and Allen H. Renear
    Journal of the Association for Information Science and Technology 69 763-772. 2018.
    Textual entailment is a relationship that obtains between fragments of text when one fragment in some sense implies the other fragment. The automation of textual entailment recognition supports a wide variety of text-based tasks, including information retrieval, information extraction, question answering, text summarization, and machine translation. Much ingenuity has been devoted to developing algorithms for identifying textual entailments, but relatively little to saying what textual entailmen…Read more

    Notre Dame Philosophical Reviews. 2018.
    A review of Jody Azzouni's "Ontology without Borders". Azzouni defends "ontological projectivism", a variety of ontological nihilism according to which "ontological borders" are not "worldly". I raise some questions about the view and about his master argument for it.

    Debunking Arguments in Metaethics and Metaphysics
    In Alvin Goldman & Brian McLaughlin (eds.), Metaphysics and Cognitive Science, Oxford University Press. pp. 337-363. 2019.
    Evolutionary debunking arguments abound, but it is widely assumed that they do not arise for our perceptual beliefs about midsized objects, insofar as the adaptive value of our object beliefs cannot be explained without reference to the objects themselves. I argue that this is a mistake. Just as with moral beliefs, the adaptive value of our object beliefs can be explained without assuming that the beliefs are accurate. I then explore the prospects for other sorts of vindications of our object be…Read more

    Austere Realism (review)
    Notre Dame Philosophical Reviews. 2008.
    The main focus of the review is Horgan and Potrč’s strategy for reconciling austere ontologies -- like their own, which includes exactly one concrete particular: “the blobject” -- with ordinary discourse about tables and the like. I try to show that, once we accept their ontological conclusions, there is no reason to prefer their conciliatory ontological-cum-semantic package to a more straightforward error-theoretic package on which we simply say lots of false things in ordinary discourse about …Read more
