    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
