[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 realist and irrealist versions respectively. First, I will develop a simple, largely empirical, argument against the realist reductive version. Later, rather more briefly, I will extend the argument to cover irrealist representationalism.

[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. First, I argue that, given general representationalist principles, no instances of a sensible property constitute the phenomenal character of the sensory experience that represents them. Second, I argue that, with two very plausible assumptions in place, no sensible property qua universal can constitute the phenomenal character of experiences either. At the end, I offer an alternative picture that is consistent with a naturalist psychosemantics for sensory experiences without embracing phenomenal externalism.

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 the current definition. Combined with the discussion of the new difficulties, there is nonetheless a need to restate the definition using slightly different terminology that will make the original intent of the current definition clearer and more precise. A restatement of the definition is proposed and its potential is discussed in light of some empirical questions that remain. [The IASP Council has now approved a revised definition and published its rationale here: Pain 2020 Sep 1; 161(9), pp. 1976–1982. The new definition follows (most of) my recommendations.]

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 context of representationalism. I argue that pain experiences, as well as some other similar experiences like itches, tickles, orgasms, hedonic valence, etc., are not transparent in this strong sense. Hence they constitute empirical counterexamples to representationalism. Given that representationalism is a general metaphysical doctrine about all experiential phenomenology for good reasons, I conclude that representationalism about phenomenal consciousness is false. Then, I outline a general framework about how the introspection of phenomenal qualities in perceptual experience works in light of the transparency datum, but consistent with the rejection of strong transparency. The result is a form of qualia realism that is naturalist and intentionalist, and has close affinities to the adverbialist views developed in the latter part of the last century. I then apply this framework to pain experiences and their bodily locations.

This 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 affective neuroscientists is usually the notion of sensory affect. It's not clear how these two notions are related to each other. I'll present the main outlines of both notions, make some critical observations, and raise a few questions at the end.

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 with: how to understand our utterances and judgments attributing pain to body parts. (The puzzle is of course general extending to all sensations routinely located in body parts.) The present work tackles this puzzle. I go over various options specifying the truth-conditions for pain attributing judgments, and at the end make my own recommendation which is an adverbialist, qualia-friendly proposal with completely naturalistic credentials that is also compatible with forms of weak intentionalism. The results are generalizable to other bodily sensations and can be used to illustrate, quite generally, the viability of a qualia-friendly adverbialist (but naturalist and weakly intentionalist) account of perception.

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 can also be processed in a structure sensitive way. Surprisingly, Fodor and McLaughlin seem to agree: such models are non-classical. I develop an abstract notion of syntax and of what it is to be structure sensitive that classicism is essentially committed to. Consequently, I argue that implementation of this minimal abstract notion is enough to explain the cognitive regularities that had prompted to postulate a LOT in the first place. Any model that satisfies a formal system in this abstract sense ought to be seen as a classical LOT model. I show that concatenative or non-concatenative realization of complex representations is an implementation level issue and as such is irrelevant for an essentialist defense of the LOTH. ;I also criticize Stich's Syntactic theory of Mind, and show that the STM has nothing to do with syntax when the notion of syntax is properly understood. First, I argue that if Stich is right in his claim that content-based psychologies have the disadvantages he enumerates, then STM-style theories have exactly the parallel problems; so it is false that the STM framework is scientifically superior to content-based psychologies as Stich claims. Secondly, I argue that the STM as a version of a narrow causal individuation scheme cannot type-individuate abstract syntactic objects onto which the brain states, according to Stich, are supposed to be mapped. Thirdly, I show that the STM-theorist, at any rate, is committed to intentional vocabulary at some stage of theory construction. ;I argue that since a NCA of typing Mentalese expressions is bankrupt, the only individuation scheme is semantic and a molecularist one at that: I criticize Fodor's purely denotational semantics. I also discuss how this provides the right perspective in answering one troublesome question for intentional psychology: if psychological processes are computational, how can psychological laws be intentional?

  Fodor and Pylyshyn's 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 like Smolensky took the challenge very seriously, and attempted to meet it by developing models that were supposed to be non-classical. At the core of these attempts lies the claim that connectionist models can provide a representational system with a combinatorial syntax and processes sensitive to syntactic structure. They are not implementation models because, it is claimed, the way they obtain syntax and structure sensitivity is not "concatenative," hence "radically different" from the way classicists handle them. In this paper, I offer an analysis of what it is to physically satisfy/realize a formal system. In this context, I examine the minimal truth-conditions of LOT Hypothesis. From my analysis it will follow that concatenative realization of formal systems is irrelevant to LOTH since the very notion of LOT is indifferent to such an implementation level issue as concatenation. I will conclude that to the extent to which they can explain the law-like cognitive regularities, a certain class of connectionist models proposed as radical alternatives to the classical LOT paradigm will in fact turn out to be LOT models, even though new and potentially very exciting ones

ABSTRACT. Fodor characterizes concepts as consisting of two dimensions: one is content, which is purely denotational/broad, the other the Mentalese vehicle bearing that content, which Fodor calls the Mode of Presentation (MOP), understood "syntactically." I argue that, so understood, concepts are not interpersonally sharable; so Fodor's own account violates what he calls the Publicity Constraint in his (1998) book. Furthermore, I argue that Fodor's non-semantic, or "syntactic," solution to Frege cases succumbs to the problem of providing interpersonally applicable functional roles for MOPs. This is a serious problem because Fodor himself has argued extensively that if Fregean senses or meanings are understood as functional/conceptual roles, then they can't be public, since, according to Fodor, there are no interpersonally applicable functional roles in the relevant senses. I elaborate on these relevant senses in the paper.

This paper is an attempt to spell out what makes the scientific study of pain so distinctive from a philosophical perspective. Using the IASP definition of ‘pain’ as our guide, we raise a number of questions about the philosophical assumptions underlying the scientific study of pain. We argue that unlike the study of ordinary perception, the study of pain focuses from the very start on the experience itself and its qualities, without making deep assumptions about whether pain experiences are perceptual. This in turn puts scientific explanation in a curious position due to pain’s inherently subjective epistemic nature. The reason for this focus on the experience itself and its qualities, we argue, has to do with pain’s complex phenomenology involving an affective/motivational dimension. We argue for the scientific legitimacy of first‐person phenomenological studies and attempts to correlate phenomenology with neural events. We argue that this methodological procedure is inevitable and has no anti‐physicalist ontological implications when properly understood. We end the paper by commenting on a discussion between two prominent pain scientists in the field, Don Price and Howard Fields, about the need to distinguish more dimensions in the phenomenology of pain and how to classify them vis‐à‐vis the recent scientific findings. Our interest in this discussion is not only to introduce some clarifications but also to show how “neurophenomenology” has already been shaping the scientific research and to back our claim about why this methodology is inevitable with an example

According to the Computational/Representational Theory of Thought (CRTT ? Language of Thought Hypothesis, or LOTH), propositional attitudes, such as belief, desire, and the like, are triadic relations among subjects, propositions, and internal mental representations. These representations form a representational _system_ physically realized in the brain of sufficiently sophisticated cognitive organisms. Further, this system of representations has a combinatorial syntax and semantics, but the processes that operate on the representations are causally sensitive only to their syntax, not to their semantics. On this approach, a first pass account of propositional attitudes is the following (cf. Field 1978: 37 and Fodor 1987: 17)

[This is the penultimate version, please send me an email for the final version]. Some sensations are pleasant, some unpleasant, and some are neither. Furthermore, those that are pleasant or unpleasant are so to different degrees. In this essay, I want to explore what kind of a difference is the difference between these three kinds of sensations. I will develop a comprehensive three-level account of sensory pleasure that is simultaneously adverbialist, functionalist and is also a version of a satisfied experiential-desire account.

Some sensory experiences are pleasant, some unpleasant. This is a truism. But understanding what makes these experiences pleasant and unpleasant is not an easy job. Various difficulties and puzzles arise as soon as we start theorizing. There are various philosophical theories on offer that seem to give different accounts for the positive or negative affective valences of sensory experiences. In this paper, we will look at the current state of art in the philosophy of mind, present the main contenders, critically compare and contrast them. In particular, we want to examine how they handle the reason-giving power of affective states. We will look into two representationalist proposals (Evaluativism and Imperativism) and a functionalist proposal, and argue that, contrary to their own advertisements, the representationalist proposals don’t have good accounts of why and how sensory affect can motivate, rationalize, and justify subsequent behavior and intentional mental activity. We will show that our own functionalist proposal does a much better job in this regard, and that when the representationalist proposals are modified to do a better job, they fare better not because of their representationalist credentials but due to their functionalist ones.

What does feeling a sharp pain in one's hand have in common with seeing a red apple on the table? Some say not much, apart from the fact that they are both conscious experiences. To see an object is to perceive an extramental reality -- in this case, a red apple. To feel a pain, by contrast, is to undergo a conscious experience that doesn't necessarily relate the subject to an objective reality. Perceptualists, however, dispute this. They say that both experiences are forms of perception of an objective reality. Feeling a pain in one's hand, according to this view, is perceiving an objective condition of one's hand. Who is closer to truth? Because of such metaphysical issues, the subjectivity of pains combined with their clinical urgency raises methodological problems for pain scientists. How can a subjective phenomenon be studied objectively? What is the role of the first-person method in science? Some suggest that the subjectivity of pains is due to their metaphysical irreducibility to purely physical processes in the nervous system. Can this be true? The study of pain and its puzzles offers opportunities for understanding such larger issues as the place of consciousness in the natural order and the methodology of psychological research. In this book, leading philosophers and scientists offer a wide range of views on how to conceptualize and study pain. The essays include discussions of perceptual and representationalist accounts of pain; the affective-motivational dimension of pain; whether animals feel pain, and how this question can be investigated; how social pain relates to physical pain; whether first-person methods of gathering data can be integrated with standard third-person methods; and other methodological and theoretical issues in the science and philosophy of pain

A comprehensive introduction to the Language of Though Hypothesis (LOTH) accessible to general audiences. 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, thought is, roughly, the tokening of a representation that has a syntactic (constituent) structure with an appropriate semantics. Thinking thus consists in syntactic operations defined over representations. Most of the arguments for LOTH derive their strength from their ability to explain certain empirical phenomena like productivity, systematicity of thought and thinking

In The Elm and the Expert (1994), Fodor rejects the notion of narrow content as superfluous. He envisions a scientific intentional psychology that adverts only to broad content properties in its explanations. I show that there has been no change in Fodor's treatment of Frege cases and cases involving the so‐called deferential concepts. And for good reason: his notion of narrow content (1985‐91) couldn't explain them. The only apparent change concerns his treatment of Twin Earth cases. However, I argue that the notion of broad content that his purely informational semantics delivers is, in some interesting sense, equivalent to the mapping notion of narrow content he officially gave up. I also critically reconstruct the evolution of Fodor's thinking between 1980 and 1994.

The relation between computational and intentional psychology has always been a vexing issue. The worry is that if mental processes are computational, then these processes, which are defined over symbols, are sensitive solely to the non-semantic properties of symbols. If so, perhaps psychology could dispense with adverting in its laws to intentional/semantic properties of symbols. Stich, as is well-known, has made a great deal out of this tension and argued for a purely "syntactic" psychology by driving a wedge between a semantic individuation of symbol tokens and their narrow functional individuation. If the latter can be carried out, he claimed, we do not need semantic typing. I argue that since a narrow functional individuation cannot type-identify symbol tokens across organisms, a semantic account of typing must be the only option given that interpersonal physical individuation of tokens is not to be taken seriously.

This is a slightly more polished version of a presentation I wrote for the Author-Meets-Critics session on Colin's book at the Eastern APA session on Jan 4, 2017, in Baltimore. I’ve decided to post this commentary online pretty much as is -- I am afraid I don't have time to prepare a version suitable for publication. I hope the reader will find it helpful. At any rate, please treat this piece as a rough draft originally intended to be delivered to a live audience. Although my commentary is mostly critical, I admire Colin's book for its originality, breadth, and depth. It stimulated my thought like no other books in recent years

Since its inception some fifty years ago, cognitive science has seen a number of sea changes. Perhaps the best known is the development of connectionist models of cognition as an alternative to classical, symbol-based approaches. A more recent - and increasingly influential - trend is that of dynamical-systems-based, ecologically oriented models of the mind. Researchers suggest that a full understanding of the mind will require systematic study of the dynamics of interaction between mind, body, and world. Some argue that this new orientation calls for a revolutionary new metaphysics of mind, according to which mental states and processes, and even persons, literally extend into the environment. This book is a guide to this movement in cognitive science. Each chapter tackles either a specific area of empirical research or specific sector of the conceptual foundation underlying this research.

Pain is the most prominent member of a class of sensations known as bodily sensations, which includes itches, tickles, tingles, orgasms, and so on. Bodily sensations are typically attributed to bodily locations and appear to have features such as volume, intensity, duration, and so on, that are ordinarily attributed to physical objects or quantities. Yet these sensations are often thought to be logically private, subjective, self-intimating, and the source of incorrigible knowledge for those who have them. Hence there appear to be reasons both for thinking that pains (along with other similar bodily sensations) are physical objects or conditions that we perceive in body parts, and for thinking that they are not. This apparent paradox is one of the main reasons why philosophers are especially interested in pain. One increasingly popular but still controversial way to deal with this apparent paradox is to defend a perceptual or representational view of pain, according to which feeling pain is in principle no different from undergoing other standard perceptual processes like seeing, hearing, touching, etc. But there are many who think that pains are not amenable to such a treatment. Although it was the treatment of pain as a sensory-discriminative experience that had dominated the philosophical discussions throughout most of the twentieth century, attention to pains’ affective-motivational dimension has gained prominence in recent years.
