196An Objection to the Laplacean ChalmersJournal for General Philosophy of Science / Zeitschrift für Allgemeine Wissenschaftstheorie 47 (1): 237-240. 2016.I discuss David Chalmers’ “scrutability thesis,” roughly that a Laplacean intellect could know every truth about the universe from a “compact class” of basic truths. It is argued that despite Chalmers’ remarks to the contrary, the thesis is problematic owing to quantum indeterminacy. Chalmers attempts to “frontload” various principles into the compact class to help out. But though frontloading may succeed in principle, Chalmers does not frontload enough to avoid the problem.

403Self‐Knowledge and Externalism about Empty ConceptsAnalytic Philosophy 56 (2): 158-168. 2015.Several authors have argued that, assuming we have apriori knowledge of our own thought-contents, semantic externalism implies that we can know apriori contingent facts about the empirical world. After presenting the argument, I shall respond by resisting the premise that an externalist can know apriori: If s/he has the concept water, then water exists. In particular, Boghossian's Dry Earth example suggests that such thought-experiments do not provide such apriori knowledge. Boghossian himself r…Read more

256In the Mental Fiction, Mental Fictionalism is FictitiousThe Monist 96 (4): 605-621. 2013.Here I explore the prospects for fictionalism about the mental, modeled after fictionalism about possible worlds. Mental fictionalism holds that the mental states posited by folk psychology do not exist, yet that some sentences of folk psychological discourse are true. This is accomplished by construing truths of folk psychology as “truths according to the mentalistic fiction.” After formulating the view, I identify five ways that the view appears self-refuting. Moreover, I argue that this canno…Read more

308_Self-Reflection for the Opaque Mind_ attempts to solve a grave problem about critical self-reflection. Psychological studies indicate not just that we are bad at detecting our own "ego-threatening" thoughts; they also suggest that we are ignorant of even our ordinary thoughts. However, self-reflection presupposes an ability to know one’s own thoughts. So if ignorance is the norm, why attempt self-reflection? While admitting the psychological data, this book argues that we are infallible in a li…Read more

193Quine and logical truthErkenntnis 68 (1). 2008.It is a consequence of Quine’s confirmation holism that the logical laws are in principle revisable. Some have worried this is at odds with another dictum in Quine, viz., that any translation which construes speakers as systematically illogical is ipso facto inadequate. In this paper, I try to formulate exactly what the problem is here, and offer a solution to it by (1) disambiguating the term ‘logic,’ and (2) appealing to a Quinean understanding of ‘necessity.’ The result is that the different …Read more

263[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

187On the PROVER9 Ontological ArgumentPhilosophia 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

172Content Externalism and Quine’s Criterion are IncompatibleErkenntnis 82 (3): 625-639. 2017.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

323The Modal Ontological Argument Meets Modal FictionalismAnalytic 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

360Knowing‐Wh and Embedded QuestionsPhilosophy 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
