Qualia that It Is Right to Quine*

Dennett (1988) provides a much discussed argument for the nonexistence of qualia, as conceived by philosophers like Block, Chalmers, Loar and Searle. My goal in this paper is to vindicate Dennett's argument, construed in a certain way. The argument supports the claim that qualia are constitutively representational. Against Block and Chalmers, the argument rejects the detachment of phenomenal from information‐processing consciousness; and against Loar and Searle, it defends the claim that qualia are constitu‐tively representational in an externalist understanding of this. The core of the argument is contained in section 3. In the first part, I contrast a minimal conception of qualia, relative to which their existence is not under dispute, with the sort of view to which I will object. In the second part I set the stage by presenting the facts about (minimal) qualia on which a Dennett‐like argument can be based.     

Physicalism,Qualia Inversion,And Affective States

I argue that the inverted spectrum hypothesis is nota possibility we should take seriously. The principlereason is that if someone's qualia were inverted inthe specified manner there is reason to believe thephenomenal difference would manifest itself inbehaviour. This is so for two reasons. First, Isuggest that qualia, including phenomenal colours, arepartly constituted by an affective component whichwould be inverted along with the connected qualia. Theresulting affective inversions will, given theintimate connections that exist between emotions andbehaviour, likely manifest themselves in behaviour, inwhich case the underlying phenomenal differences canbe functionally captured. Second, I argue that othersense modalities lack the structural featuresnecessary for undetectable inversion which, because oftheir analogy with colour qualia, weakens theplausibility of such an inversion in the original caseof vision.     

Against qualia theory

Representational theorists identify experiences’ phenomenal properties with their representational properties. Qualia theorists reject this identity, insisting that experiences’ phenomenal properties can come apart from and completely outrun their representational properties. Qualia theorists account for phenomenal properties in terms of “qualia,” intrinsic mental properties they allege experiences to instantiate. The debate between representational theorists and qualia theorists has focused on whether phenomenal properties really can come apart from and completely outrun representational properties. As a result, qualia theorists have failed (1) to explain how experiences owe their phenomenal properties to their instantiation of qualia and (2) to clarify the nature of subjects’ epistemic access to qualia. I survey qualia theorists’ options for dealing with each issue and find them all wanting.     

The irrelevance of folk intuitions to the "hard problem" of consciousness

Recently, a number of philosophers have turned to folk intuitions about mental states for data about qualia and phenomenal consciousness. In this paper I argue that current research along these lines does not tell us about these subjects. I focus on a series of studies, performed by Justin Sytsma and Edouard Machery, to make my argument. Folk judgments studied by these researchers are mostly likely generated by a certain cognitive system - System One - that will generate the same data whether or not we experience phenomenal consciousness. This is a problem for a range of current experimental philosophy research into consciousness or our concept of it. If experimental philosophy is to shed light into phenomenal consciousness, it needs to be better founded in an understanding of how we make judgments.     

What is it Like to be a Phenomenologist?

In a recent paper, 'On the Persistence of Phenomenology' (in T. Metzinger (ed.), Conscious Experience , Paderborn, 1995), Diana Raffman presents a new argument for qualia, an argument that provides new focus for the qualia debate. We think Raffman's work relocates the debate to a better neighbourhood, a neighbourhood in which what tempts us to think that there must be qualia or phenomenal information is highlighted. Raffman, we argue, locates the core thought shared by many of the friends of qualia, namely, that our conceptual resources are inadequate for capturing the richness of experience. Experience is ineffably determinate. Moreover, Raffman's argument in support of this thought seems especially embarrassing to scientific-minded materialists, since the argument relies largely on well established empirical facts. We show, however, that Raffman's argument fails. So, if we are correct that her argument highlights what is tempting about qualia, then we have also shown that it is not tempting.     

Phenomenal character, phenomenal concepts, and externalism

A celebrated problem for representationalist theories of phenomenal character is that, given externalism about content, these theories lead to externalism about phenomenal character. While externalism about content is widely accepted, externalism about phenomenal character strikes many philosophers as wildly implausible. Even if internally identical individuals could have different thoughts, it is said, if one of them has a headache, or a tingly sensation, so must the other. In this paper, I argue that recent work on phenomenal concepts reveals that, contrary to appearances, this standard conjunction of externalism about content and internalism about phenomenal character is ultimately untenable on other models of phenomenal character as well, including even “qualia realism.” This would be significant for a number of reasons. The first is patent: it would undermine a primary objection to representationalism. The fact that representationalism is incompatible with the conjunction would be no serious problem for representationalism if no other plausible model of phenomenal character is compatible with it. The second is that the many philosophers who embrace the conjunction would be forced to abandon one of the two views; externalism would be true either of both content and phenomenal character, or of neither. Likewise, those philosophers who have taken a stance on only one of the two internalism/externalism debates would have to be seen as thereby committed to a particular stance on the other. The third reason stems from the fact that qualia realism typically goes hand in hand with internalism about phenomenal character. To the extent that it does, my argument would reveal that qualia realism is itself in tension with externalism about content. This would perhaps be the most surprising result of all.     

Everything is clear: All perceptual experiences are transparent

The idea that perceptual experience is transparent is generally used by naïve realists and externalist representationalists to promote an externalist account of the metaphysics of perceptual experience. It is claimed that the phenomenal character of our perceptual experience can be explained solely with reference to the externally located objects and properties which (for the representationalist) we represent, or which (for the naïve realist) partly constitute our experience. Internalist qualia theorists deny this and claim that the phenomenal character of our perceptual experience is internally constituted. However, my concern in this paper is not with the metaphysical debate but with transparency as a phenomenological feature of perceptual experience. Qualia theorists have presented a number of examples of perceptual experiences which, they claim, do not even seem to be transparent; these experiences involve objects or properties which seem to be internally realized. I argue, contrary to the qualia theorist's claim, that the phenomenal character of perceptual experience can in fact be characterized solely with reference to externally located objects and properties, and the sense in which some features of our perceptual experiences do not seem external is due to cognitive, not perceptual, phenomenology.     

Vindicating the Absent Qualia Objection

Metaphysical functionalism holds that the nature of the mental is its functional role. Proponents of the absent qualia objection to functionalism assert that mental states with essential phenomenal qualities might have had functional duplicates without qualia. Michael Tye has argued that this purported possibility is incoherent. Robert van Gulick has criticized Tye's argument. It is contended here that although van Gulick's criticism does not refute the argument, Tye's argument is unsuccessful. It is also contended that our evidence very strongly supports the possibility of absent qualia.     

Blurring two conceptions of subjective experience: Folk versus philosophical phenomenality

Philosophers and psychologists have experimentally explored various aspects of people's understandings of subjective experience based on their responses to questions about whether robots “see red” or “feel frustrated,” but the intelligibility of such questions may well presuppose that people understand robots as experiencers in the first place. Departing from the standard approach, I develop an experimental framework that distinguishes between “phenomenal consciousness” as it is applied to a subject (an experiencer) and to an (experiential) mental state and experimentally test folk understandings of both subjective experience and experiencers. My findings (1) reveal limitations in experimental approaches using “artificial experiencers” like robots, (2) indicate that the standard philosophical conception of subjective experience in terms of qualia is distinct from that of the folk, and (3) show that folk intuitions do support a conception of qualia that departs from the philosophical conception in that it is physical rather than metaphysical. These findings have implications for the “hard problem” of consciousness.     

Phenomenal Concepts and Higher-Order Experiences

Relying on a range of now-familiar thought-experiments, it has seemed to many philosophers that phenomenal consciousness is beyond the scope of reductive explanation. (Phenomenal consciousness is a form of state-consciousness, which contrasts with creature-consciousness, or perceptual -consciousness. The different forms of state-consciousness include various kinds of access-consciousness, both first-order and higher-order–see Rosenthal, 1986; Block, 1995; Lycan, 1996; Carruthers, 2000. Phenomenal consciousness is the property that mental states have when it is like something to possess them, or when they have subjectively-accessible feels; or as some would say, when they have qualia (see fn. l below).) Others have thought that we can undermine the credibility of those thought-experiments by allowing that we possess purely recognitional concepts for the properties of our conscious mental states. This paper is concerned to explain, and then to meet, the challenge of showing how purely recognitional concepts are possible if there are no such things as qualia –in the strong sense of intrinsic (non relational, non-intentional) properties of experience. It argues that an appeal to higher-order experiences is necessary to meet this challenge, and then deploys a novel form of higher-order thought theory to explain how such experiences are generated.     

Internalism and the snapshot conception of phenomenal experience: A reply to Fisher

Justin Fisher (2007) has presented a novel argument designed to prove that all forms of mental internalism are false. I aim to show that the argument fails with regard to internalism about phenomenal experiences. The argument tacitly assumes a certain view about the ontology of phenomenal experience, which (inspired by Alva Noë) I call the “snapshot conception of phenomenal experience.” After clarifying what the snapshot conception involves, I present Fisher with a dilemma. If he rejects the snapshot conception, then his argument against phenomenal internalism collapses. But if he embraces the snapshot conception, then internalists may argue that in light of the snapshot conception, their view is not so implausible—and that if Fisher still disagrees, he owes us an argument that shows why phenomenal internalism is false even given the snapshot conception. I conclude the paper by showing that Fisher cannot escape my criticism by adjusting his argument so that it no longer depends on the snapshot conception.     

Consciousness,Idealism, and Skepticism: Reflections on Jay Garfield’s <Emphasis Type="Italic">Engaging Buddhism</Emphasis>

Jay Garfield’s Engaging Buddhism admirably shows the relevance of Indian philosophy to the interests of mainstream analytic Anglophone philosophers. Garfield deploys the Indian tradition to critique phenomenal realism, the view that there really are qualia or phenomenal properties—that there really is ‘something it’s like’ to be undergoing the experience you are undergoing right now. I argue that Garfield’s critique probably turns on a false dilemma that omits the possibility of introspection as a fallible tool for getting at a real stream of experience that may or may not be accurately reported. Garfield also argues that if we are phenomenal realists, metaphysical idealism remains a philosophical possibility, whereas if we join him in rejecting phenomenal realism then we can also justifiably reject metaphysical idealism. I accept this conditional but reverse its valence: One advantage of phenomenal realism, and also of engaging with the Indian philosophical tradition, is that it opens up wonderful possibilities, like metaphysical idealism, that mainstream analytic Anglophone philosophers tend to too swiftly dismiss.     

Ramseyan humility: the response from revelation and panpsychism

David Lewis argues for Ramseyan humility, the thesis that we can’t identify the fundamental properties that occupy the nomological roles at our world. Lewis, however, remarks that there is a potential exception to this, which involves assuming two views concerning qualia (i) panphenomenalism (contemporary panpsychism): all instantiated fundamental properties are qualia and (ii) the identification thesis (revelation): we can know the identities of our qualia simply by being acquainted with them. This paper aims to provide an exposition, as well as an assessment, of this response to the humility thesis.     

I—From Property Dualism to Substance Dualism

Property dualism is enjoying a slight resurgence in popularity, these days; substance dualism, not so much. But it is not as easy as one might think to be a property dualist and a substance materialist. The reasons for being a property dualist support the idea that some phenomenal properties (or qualia ) are as fundamental as the most basic physical properties; but what material objects could be the bearers of the qualia? If even some qualia require an adverbial construal (if they are modifications of the thing that is conscious because of them, not properties of something else to which the subject of consciousness is related), then the property dualist can be driven to speculative forms of materialism none of which, at this point, looks more likely to be true than the more modest versions of emergent dualism defended by contemporary substance dualists.     

Towards a computational theory of experience

A standing challenge for the science of mind is to account for the datum that every mind faces in the most immediate – that is, unmediated – fashion: its phenomenal experience. The complementary tasks of explaining what it means for a system to give rise to experience and what constitutes the content of experience (qualia) in computational terms are particularly challenging, given the multiple realizability of computation. In this paper, we identify a set of conditions that a computational theory must satisfy for it to constitute not just a sufficient but a necessary, and therefore naturalistic and intrinsic, explanation of qualia. We show that a common assumption behind many neurocomputational theories of the mind, according to which mind states can be formalized solely in terms of instantaneous vectors of activities of representational units such as neurons, does not meet the requisite conditions, in part because it relies on inactive units to shape presently experienced qualia and implies a homogeneous representation space, which is devoid of intrinsic structure. We then sketch a naturalistic computational theory of qualia, which posits that experience is realized by dynamical activity-space trajectories (rather than points) and that its richness is measured by the representational capacity of the trajectory space in which it unfolds.     

Hill on phenomenal consciousness

I argue that it is at least open to a proponent of type materialism for phenomenal consciousness to accept Hill’s representational theory of experiential awareness of perceptual qualia.     

Affect,perceptual experience,and disclosure

A prominent number of contemporary theories of emotional experience—understood as occurrent, phenomenally conscious episodes of emotions with an affective character that are evaluatively directed towards particular objects or states of affairs—are motivated by the claim that phenomenally conscious affective experience, when appropriate, grants us epistemic access not merely to features of the experience but also to features of the object of experience, namely its value. I call this the claim of affect as a disclosure of value. The aim of this paper is to clarify the sort of assumptions about experience that we ought to avoid if we want to be able to argue that for the claim of affect as a disclosure of value. There are two core arguments in this paper. First, I argue that Mark Johnston’s account of affect as a disclosure of value, due to its naïve realist commitments, relapses into a position that is vulnerable to the same objection put forward by some naïve realists against intentionalist accounts of perceptual experience. Second, I argue that Michelle Montague’s account, due to its phenomenal intentionalist commitments, relapses into a position that is vulnerable to the same objections put forward against qualia theories of the phenomenal character of perceptual experience. The upshot of the paper is that the core assumptions embedded in the three dominant models of experience—namely naïve realism, different versions of intentionalism, and qualia theory—are problematic as found in contemporary accounts of affect as a disclosure of value.     

Qualia and vagueness

In this paper I present two arguments against the thesis that we experience qualia. I argue that if we experienced qualia then these qualia would have to be essentially vague entities. And I then offer two arguments, one a reworking of Gareth Evans' argument against the possibility of vague objects, the other a reworking of the Sorites argument, to show that no such essentially vague entities can exist. I consider various objections but argue that ultimately they all fail. In particular I claim that the stock responses to the Sorites argument fail against my reworking of the argument because they require us to make a distinction between a determinate reality and how that reality appears to us, whereas in the case of qualia we can make no such distinction. I conclude that there can be no such things as qualia.I would like to thank the referees and Leopold Stubenberg for their help and comments.     

The Scientific Untraceability of Phenomenal Consciousness

It is a common conviction among philosophers who hold that phenomenal properties, qualia, are distinct from any cognitive, intentional, or functional properties, that it is possible to trace the neural correlates of these properties. The main purpose of this paper is to present a challenge to this view, and to show that if “non-cognitive” phenomenal properties exist at all, they lie beyond the reach of neuroscience. In the final section it will be suggested that they also lie beyond the reach of psychology, so that they may be said to lie beyond the reach of science.
