86Computation and functionalism: Syntactic theory of mind revisitedIn G. Irzik & Güven Güzeldere (eds.), Turkish Studies in the History and Philosophy of Science, Springer. 2005.There is a thesis often aired by some philosophers of psychology that syntax is all we need and there is no need to advert to intentional/semantic properties of symbols for purposes of psychological explanation. Indeed, the worry has been present since the first explicit articulation of so-called Computational Theory of Mind (CTM). Even Fodor, who has been the most ardent defender of the Language of Thought Hypoth- esis (LOTH) (which requires the CTM), has raised worries about its apparent conse…Read more

The experimental use of introspection in the scientific study of painIn Murat Aydede (ed.), Pain: New Essays on its Nature and the Methodology of its Study, Mit Press. 2005.Understanding the nature of pain depends, at least partly, on recognizing its subjectivity (thus, its first-person epistemology). This in turn requires using a first-person experiential method in addition to third-person experimental approaches to study it. This paper is an attempt to spell out what the former approach is and how it can be integrated with the latter. We start our discussion by examining some foundational issues raised by the use of introspection. We argue that such a first-perso…Read more

2Consider the following two sentences: (1) I see a dark discoloration in the back of my hand. (2) I feel a jabbing pain in the back of my hand. They seem to have the same surface grammar, and thus prima facie invite the same kind of semantic treatment. Even though a reading of see in (1) where the verb is not treated as a success verb is not out of the question, it is not the ordinary and natural reading. Note that if I am hallucinating a dark discoloration in the back of my hand, then (1) is sim…Read more

268Is Pain Representational?Belgrade Philosophical Annual. forthcoming.[Special issue honoring Nikola Grahek] Representationalism in philosophy of perception has become more or less the dominant view. There are various versions of it not all of which are motivated by the same set of concerns. Different metaphysical and epistemological agendas are at work in different strands of the movement. In this paper, I will focus on what has come to be known as strong representationalism. This view has reductive and non-reductive versions, which are usually paired with re…Read more

1075Are Frege cases exceptions to intentional generalizations?Canadian Journal of Philosophy 31 (1): 1-22. 2001.This piece criticizes Fodor's argument (in The Elm and the Expert, 1994) for the claim that Frege cases should be treated as exceptions to (broad) psychological generalizations rather than as counterexamples.

510[Working Draft — Comments are welcome! — March 2024] Reductive strong representationalists accept the Common Kind Thesis about subjectively indistinguishable sensory hallucinations, illusions, and veridical experiences. I show that this doesn’t jibe well with their declared phenomenal externalism and argue that there is no sense in which the phenomenal character of sensory experiences is constituted by the sensible properties represented by these experiences, as representationalists claim. Fir…Read more

720Does the IASP Definition of Pain Need Updating?PAIN Reports 4 (5 - e777): 1-7. 2019.The current IASP definition of pain has come under renewed criticisms recently. There is a new momentum for its revision as reflected by the fact that IASP has now a Presidential Task Force dedicated to look into whether there is enough warrant to update the definition. I critically review all the major criticisms of the current definition in detail, and raise new difficulties rarely discussed before. I show that none of the major criticisms has enough warrant to force us to substantially revise…Read more

813Is the experience of pain transparent? Introspecting Phenomenal QualitiesSynthese 196 (2): 677-708. 2019.I distinguish between two claims of transparency of experiences. One claim is weaker and supported by phenomenological evidence. This I call the transparency datum. Introspection of standard perceptual experiences as well as bodily sensations is consistent with, indeed supported by, the transparency datum. I formulate a stronger transparency thesis that is entailed by representationalism about experiential phenomenology. I point out some empirical consequences of strong transparency in the conte…Read more

329This is the text of an invited talk exploring the connections between two apparently distinct notions of affect, sensory versus core affect. It is basically a progress report. It is exploratory and tentative. It starts from a mild puzzle about the apparent mismatch between the notion of affect that affective neuroscientists generally deploy and the notion of affect that emotion psychologists deploy. The notion favored by psychologists is the notion of core affect. The phenomenon studied by affec…Read more

685What is a pain in a body part?Canadian Journal of Philosophy 50 (2). 2020.The IASP definition of 'pain' defines pain as a subjective experience. The Note accompanying the definition emphasizes that as such pains are not to be identified with objective conditions of body parts (such as actual or potential tissue damage). Nevertheless, it goes on to state that a pain "is unquestionably a sensation in a part or parts of the body, but it is also always unpleasant and therefore also an emotional experience." This generates a puzzle that philosophers have been well familiar…Read more

Syntax, Functionalism, Connectionism, and the Language of ThoughtDissertation, University of Maryland, College Park. 1993.Fodor and Pylyshyn's critique of connectionism has posed a challenge to connectionists: Explain such cognitive regularities as systematicity and productivity without postulating a LOT architecture. Some connectionists took the challenge seriously. They developed some models that purport to show that they can explain the regularities without becoming classical. The key to their claim is that their models can and do provide non-concatenatively realized syntactically complex representations that ca…Read more

642[This is an earlier (1997), much longer and more detailed version of my entry on LOTH in the _Stanford Encyclopedia of Philosophy_] The Language of Thought Hypothesis (LOTH) is an empirical thesis about thought and thinking. For their explication, it postulates a physically realized system of representations that have a combinatorial syntax (and semantics) such that operations on representations are causally sensitive only to the syntactic properties of representations. According to LOTH, though…Read more

944How to Unify Theories of Sensory Pleasure: An Adverbialist ProposalReview of Philosophy and Psychology 5 (1): 119-133. 2014.A lot of qualitatively very different sensations can be pleasant or unpleasant. The Felt-Quality Views that conceive of sensory affect as having an introspectively available common phenomenology or qualitative character face the “heterogeneity problem” of specifying what that qualitative common phenomenology is. In contrast, according to the Attitudinal Views, what is common to all pleasant or unpleasant sensations is that they are all “wanted” or “unwanted” in a certain sort of way. The commona…Read more

102Connectionism and the language of thoughtCSLI Technical Report. 1995.Fodor and Pylyshyn's (F&P) critique of connectionism has posed a challenge to connectionists: Adequately explain such nomological regularities as systematicity and productivity without postulating a "language of thought'' (LOT). Some connectionists declined to meet the challenge on the basis that the alleged regularities are somehow spurious. Some, like Smolensky, however, took the challenge very seriously, and attempted to meet it by developing models that are supposed to be non-classical

72Critical comments on Williams and Craig’s recent proposal for revising the definition of painPAIN 158 (2): 362-363. 2017.[DOI: 10.1097/j.pain.0000000000000765] Amanda Williams and Kenneth Craig, in a recent article in the IASP official journal _Pain_ (DOI: 10.1097/j.pain.0000000000000613), have argued that it is time to revise the IASP's well-entrenched definition of 'pain'. They propose an alternative definition. We critically discuss their proposed revision and argue that it admits clear counterexamples as both sufficient and necessary conditions. We further discuss the wisdom of replacing 'unpleasant' in the I…Read more

69Pain, philosophical aspects ofIn Patrick Wilken, Timothy J. Bayne & Axel Cleeremans (eds.), The Oxford Companion to Consciousness, Oxford University Press. pp. 495-498. 2009.The ordinary conception of pain has two major threads that are in tension with each other. It is this tension that generates various puzzles in our philosophical understanding of pain. This is a short encyclopedia entry surveying some of the major philosophical puzzles about pain.

120Emotions or emotional feelings? (Commentary on Rolls' The Brain and Emotion)Behavioral and Brain Sciences 23 (2): 192-194. 2000.It turns out that Rolls’s answer to Nagel’s (1974) question, "What is it like to be a bat?" is brusque: there is nothing it is like to be a bat . . . provided that bats don’t have a linguistically structured internal representational system that enables them to think about their first-order thoughts which are also linguistically structured. For phenomenal consciousness, a properly functioning system of higher-order linguistic thought (HOLT) is necessary (Rolls 1998, p. 262). By this criterion, n…Read more

113On the relation between phenomenal and representational propertiesBehavioral and Brain Sciences 20 (1): 151-153. 1997.We argue that Block's charge of fallacy remains ungrounded so long as the existence of P-consciousness, as Block construes it, is independently established. This, in turn, depends on establishing the existence of “phenomenal properties” that are essentially not representational, cognitive, or functional. We argue that Block leaves this fundamental thesis unsubstantiated. We conclude by suggesting that phenomenal consciousness can be accounted for in terms of a hybrid set of representational and …Read more

868I argue that if we have a rich enough description of perceptual experiences from an information-theoretic viewpoint, it becomes surprisingly difficult (to put it mildly) to positively conceive philosophical zombies (as complete physical/functional duplicates that lack phenomenal consciousness). Hence, it is at best an open question whether zombies are positively conceivable. My argument requires paying close attention to the direct relation between phenomenology and information.

346Computation and Functionalism: Syntactic Theory of Mind RevisitedIn G. Irzik & Güven Güzeldere (eds.), Turkish Studies in the History and Philosophy of Science, Springer. 2005.I argue that Stich's Syntactic Theory of Mind (STM) and a naturalistic narrow content functionalism run on a Language of Though story have the same exact structure. I elaborate on the argument that narrow content functionalism is either irremediably holistic in a rather destructive sense, or else doesn't have the resources for individuating contents interpersonally. So I show that, contrary to his own advertisement, Stich's STM has exactly the same problems (like holism, vagueness, observer-rela…Read more

242Naturalism, introspection, and direct realism about painConsciousness and Emotion 2 (1): 29-73. 2001.This paper examines pain states (and other intransitive bodily sensations) from the perspective of the problems they pose for pure informational/representational approaches to naturalizing qualia. I start with a comprehensive critical and quasi-historical discussion of so-called Perceptual Theories of Pain (e.g., Armstrong, Pitcher), as these were the natural predecessors of the more modern direct realist views. I describe the theoretical backdrop (indirect realism, sense-data theories) against …Read more
