    Knowledge of One's Own Credences
    In Adam Andreotta & Benjamin Winokur (eds.), New Perspectives on Transparency and Self-Knowledge, Routledge. forthcoming.
    This paper begins with a problem stemming from Hume regarding credences about credences. Suppose one has a credence of .95 in p, and suppose one assesses the credence to be such. But suppose one’s second-order credence in this assessment is less than 1. Then, by a standard conditionalization rule, one’s credence in p becomes less than .95. Moreover, such “erosion” can iterate by considering one’s, third-, fourth-, fifth-order credences, etc. (In light of this, some have rejected higher-order cre…Read more

    A Map of Selves: Beyond Philosophy of Mind (review)
    Philosophical Quarterly 73 (3): 887-889. 2023.
    In many respects, N.M.L. Nathan's latest book feels timeless. Its brevity and pithiness especially remind one of Descartes’ Meditations; it even has similar ove.

    Against God of the Truth-Value Gaps
    Analysis. forthcoming.
    Can God create an unliftable stone? Beall & Cotnoir propose that ‘God can create an unliftable stone’ is a truth-value gap (neither true nor false). However, this yields a revenge paradox on whether God can eschew gaps. Can God avoid gappy ascriptions of power? Either way, God’s power seems to have limits. In response, it may be said that ascribing God the power to avoid gaps is itself gappy—it concerns a power that God neither has nor lacks. Yet this ends up being inconsistent, for it implies t…Read more

    Modest versus ultra-modest dialetheism
    Asian Journal of Philosophy 2 (2): 1-17. 2023.
    Jc Beall is known for defending modest dialetheism; this is the view that there are dialetheia, but only in the form of “spandrels” arising otherwise reasonable semantic terminology (e.g., the Liar paradox). Beall also regards his view as modest in partaking of a deflationary view of truth, a view where ‘true’ is a device of disquotational inference which expresses no “substantive property.” Beall supports deflationism by an appeal to Ockham’s razor; however, the premise that ‘true’ is fundament…Read more

    Some contemporary philosophers suggest that we know just by introspection that folk psychological states exist. However, such an "armchair refutation" of eliminativism seems too easy. I first attack two strategems, inspired by Descartes, on how such a refutation might proceed. However, I concede that the Cartesian intuition that we have direct knowledge of representational states is very powerful. The rest of this paper then offers an error theory of how that intuition might really be mistaken. …Read more

    What is Mental Fictionalism?
    In Tamás Demeter, T. Parent & Adam Toon (eds.), Mental Fictionalism: Philosophical Explorations, Routledge. pp. 1-24. 2022.
    This chapter introduces several versions of mental fictionalism, along with the main lines of objection and reply. It begins by considering the debate between eliminative materialism (“eliminativism”) versus realism about mental states as conceived in “folk psychology” (i.e., beliefs, desires, intentions, etc.). Mental fictionalism offers a way to transcend the debate by allowing talk of mental states without a commitment to realism. The idea is to treat folk psychology as a “story” and three di…Read more

    Mental fictionalism holds that folk psychology should be regarded as a kind of fiction. The present version gives a Lewisian prefix semantics for mentalistic discourse, where roughly, a mentalistic sentence “p” is true iff “p” is deducible from the folk psychological fiction. An eliminativist version of the view can seem self-refuting, but this charge is neutralized. Yet a different kind of “self-effacing” emerges: Mental fictionalism appears to be a mere “parasite” on a future science of cognit…Read more

    [For a planned Festschrift on William Lycan, edited by Mitch Green and Jan Michel.] Lycan (2022) sums up his (2019) _On Evidence in Philosophy_ as a “dolorous” book. This is primarily because the book claims that the field is infected with non-rational socio-psychological forces (fashion, bias, etc.) and that there is a persistent lack of consensus on philosophical questions. In this paper, I primarily rebut Lycan's second reason for dolorousness. For one, if we attend carefully to his text, his…Read more

    Mental Fictionalism: Philosophical Explorations (edited book)
    with Tamás Demeter and Adam Toon
    Routledge. 2022.
    What are mental states? When we talk about people’s beliefs or desires, are we talking about what is happening inside their heads? If so, might cognitive science show that we are wrong? Might it turn out that mental states do not exist? Mental fictionalism offers a new approach to these longstanding questions about the mind. Its core idea is that mental states are useful fictions. When we talk about mental states, we are not formulating hypotheses about people’s inner machinery. Instead, we simp…Read more

    I Think; Therefore, I am a Fiction
    In Tamás Demeter, T. Parent & Adam Toon (eds.), Mental Fictionalism: Philosophical Explorations, Routledge. 2022.
    The Cartesian thinking self may seem indisputably real. But if it is real, then so thinking, which would undercut mental fictionalism. Thus, in defense of mental fictionalism, this paper argues for fictionalism about the thinking self. In short form, the argument is: (1) If I exist outside of fiction, then I am identical to (some part of/) this biomass [= my body]. (2) If I die at t, I cease to exist at t. (3) If I die at t, no part of this biomass ceases to exist at t. (4) Therefore, no part of…Read more

    Ontological Commitment and Quantifiers
    In Ricki Bliss & James Miller (eds.), The Routledge Handbook of Metametaphysics, Routledge. 2020.
    This is a slightly opinionated review of three main factions in metaontology: Quineans, Carnapians, and Meinongians. Emphasis is given to the last camp, as the metaontological aspect of Meinongianism has been underappreciated. The final section then offers some general remarks about the legitimacy of ontology, touching on ideas I have developed in other publications.

    Colivan Commitment, vis-à-vis Moore’s Paradox
    Philosophia 47 (2): 323-333. 2019.
    This is a contribution to a symposium on Annalisa Coliva's book _The Varieties of Self-Knowledge_. I present her notion of a "commitment" and how it is used in her treatment of Moore paradoxical assertions and thoughts (e.g., "I believe that it is raining, but it is not;" "It is raining but I do not believe that it is"). The final section notes the points of convergence between her constitutivism about self-knowledge of commitments, and the constitutivism from my book _Self-Reflection for the Op…Read more

    [Draft substantially revised, September 2021] David Lewis acclimated us to talk of “nonactual concreta that exist,” regarding talking donkeys and the like. I shall argue that this was not for the best, and try to normalize a way of describing them as “actual concreta that do not exist.” The basis of this is a defense of the Meinongian thesis “there are objects of which it is true that there are no such objects,” re: fictitious and illusory objects. I first formulate the problem of negative exist…Read more

    On the PROVER9 Ontological Argument
    Philosophia 43 (2): 475-483. 2015.
    Oppenheimer & Zalta have re-formulated their non-modal version of the ontological argument, with the help of PROVER9, an automated reasoning engine. The authors end up rejecting the new argument; however, the theist has a rejoinder worth considering. But after presenting the rejoinder, I highlight that the conceivability of the being does not imply its possibility. One lesson is that even non-modal ontological arguments must engage modal matters concerning God. Another lesson is that if PROVER9 …Read more

    Externalism holds that the content of our utterances and thoughts are determined partly by the environment. Here, I offer an argument which suggests that externalism is incompatible with a natural view about ontological commitment--namely, the Quinean view that such commitments are fixed by the range of the variables in your theory. The idea in brief is that if Oscar mistakenly believes that water = XYZ, the externalist ontologically commits Oscar to two waterish kinds, whereas the Quinean commi…Read more

    The Modal Ontological Argument Meets Modal Fictionalism
    Analytic Philosophy 57 (4): 338-352. 2016.
    This paper attacks the modal ontological argument, as advocated by Plantinga among others. Whereas other criticisms in the literature reject one of its premises, the present line is that the argument is invalid. This becomes apparent once we run the argument assuming fictionalism about possible worlds. Broadly speaking, the problem is that if one defines “x” as something that exists, it does not follow that there is anything satisfying the definition. Yet unlike non-modal ontological arguments…Read more

    Knowing‐Wh and Embedded Questions
    Philosophy Compass 9 (2): 81-95. 2014.
    Do you know who you are? If the question seems unclear, it might owe to the notion of ‘knowing-wh’ (knowing-who, knowing-what, knowing-when, etc.). Such knowledge contrasts with ‘knowing-that’, the more familiar topic of epistemologists. But these days, knowing-wh is receiving more attention than ever, and here we will survey three current debates on the nature of knowing-wh. These debates concern, respectively, (1) whether all knowing-wh is reducible to knowing-that (‘generalized intellectualis…Read more

    Theory Dualism and the Metalogic of Mind-Body Problems
    In Christopher Daly (ed.), Palgrave Handbook on Philosophical Methods, Palgrave Macmillan. pp. 497-526. 2015.
    The paper defends the philosophical method of "regimentation" by example, especially in relation to the theory of mind. The starting point is the Place-Smart after-image argument: A green after-image will not be located outside the skull, but if we cracked open your skull, we won't find anything green in there either. (If we did, you'd have some disturbing medical news.) So the after-image seems not to be in physical space, suggesting that it is non-physical. In response, I argue that the green …Read more

    Externalism and “knowing what” one thinks
    Synthese 192 (5): 1337-1350. 2015.
    Some worry that semantic externalism is incompatible with knowing by introspection what content your thoughts have. In this paper, I examine one primary argument for this incompatibilist worry, the slow-switch argument. Following Goldberg , I construe the argument as attacking the conjunction of externalism and “skeptic immune” knowledge of content, where such knowledge would persist in a skeptical context. Goldberg, following Burge :649–663, 1988), attempts to reclaim such knowledge for the ext…Read more

    If a semantically open language has no constraints on self-reference, one can prove an absurdity. The argument exploits a self-referential function symbol where the expressed function ends up being intensional in virtue of self-reference. The prohibition on intensional functions thus entails that self-reference cannot be unconstrained, even in a language that is free of semantic terms. However, since intensional functions are already excluded in classical logic, there are no drastic revisionary …Read more

    Note on Induction
    Think 12 (33): 37-39. 2013.
    ExtractSome logic textbooks say, as if it were the received wisdom, that inductive arguments are partly defined by the thinker's intentions. The claim is that an inductive argument is one where the premises are intended to make the conclusion likely. This contrasts with a deductive argument, where the premises are intended to entail the conclusion. However, since entailing is one way of making more likely, a further way to distinguish induction is needed. The addition offered is that the premise…Read more

    A dilemma about kinds and kind terms
    Synthese 198 (Suppl 12): 2987-3006. 2019.
    'The kind Lion' denotes a kind. Yet many generics are thought to denote kinds also, like the subject-terms in 'The lion has a mane', 'Dinosaurs are extinct', and 'The potato was cultivated in Ireland by the end of the 17th century.' This view may be adequate for the linguist's overall purposes--however, if we limit our attention to the theory of reference, it seems unworkable. The problem is that what is often predicated of kinds is not what is predicated of the lion, dinosaurs, and the potato. …Read more

    The Empirical Case against Infallibilism
    Review of Philosophy and Psychology 7 (1): 223-242. 2016.
    Philosophers and psychologists generally hold that, in light of the empirical data, a subject lacks infallible access to her own mental states. However, while subjects certainly are fallible in some ways, I show that the data fails to discredit that a subject has infallible access to her own occurrent thoughts and judgments. This is argued, first, by revisiting the empirical studies, and carefully scrutinizing what is shown exactly. Second, I argue that if the data were interpreted to rule out a…Read more
