Phenom Cogn Sci (2007) 6:99–106 DOI 10.1007/s11097-006-9026-y Dennett on seeming Taylor Carman Published online: 14 November 2006 # Springer Science + Business Media B.V. 2006 Abstract Dennett’s eliminativist theory of consciousness rests on an implausible reduction of sensory seeming to cognitive judgment. The “heterophenomenological” testimony to which he appeals in urging that reduction poses no threat to phenomenology, but merely demonstrates the conceptual indeterminacy of smallscale sensory appearances. Phenomenological description is difficult, but the difficulty does not warrant Dennett’s neo-Cartesian claim that there is no such thing as seeming at all as distinct from judging. Key words phenomenology . Dennett . heterophenomenology Phenomenology is, in a loose sense, the study of how things seem. Yet how things seem is bound up in deep and complex ways with how they are. It is natural to suppose that any knowledge we have of how things are must be based on or mediated by how they seem. But this is not obvious. For seeming presupposes being, and in two ways. On the one hand, seeming is often, if not always, precisely, a seeming to be; to understand a seeming as a seeming is to understand it in relation to an actual or possible being. On the other hand, seemings are beings; whether they turn out to be objects or properties or events or relations, they are in any case not nothing. Or so it seems to me. In Consciousness Explained, Dennett (1991) argues, on the contrary, that there is no distinction to be drawn between how things seem to us and how we think they seem. His “heterophenomenological” approach to consciousness thus involves the systematic substitution of direct first-person observations of experience itself with overt first-person reports about experience, which can themselves then safely be regarded as publicly available behavioral data. Hetero- T. Carman (*) Department of Philosophy, Barnard College, Columbia University, 3009 Broadway, New York, NY 10027, USA e-mail: [email protected] NO9026; No of Pages 100 T. Carman phenomenology has both methodological and ontological implications. On the one hand, it discourages psychologists and cognitive scientists from simply introspecting and describing their own experiences and urges them instead to attend to verbal reports of subjects presumably undergoing various sorts of experiences. On the other hand, more ambitiously, Dennett’s approach urges us to abandon the very idea that there is a difference between seemings and judgings. His “Multiple Drafts model” of consciousness, that is, amounts to a “first-person operationalism, for it brusquely denies the possibility in principle of consciousness of a stimulus in the absence of the subject’s belief in that consciousness” (Dennett 1991: 132). Dennett’s view is what was once upon a time called “rationalism,” then “intellectualism,” then “cognitivism.” The term “intellectualism” was common in the psychological literature a century ago, though its meaning varied. William James identifies intellectualism with the Kantian thesis that sensations exist but “are combined by activity of the Thinking Principle” (James 1950: II, 27; cf. 218–19). Merleau-Ponty, by contrast, often restricts the term to the more radical idea, which Descartes and Dennett share, that sensation just is a kind of thought; that perception is cognitive “all the way down.” Like Descartes, that is, intellectualists and cognitivists want to assimilate all mental phenomena to thinking, above all believing and inferring. In Principles of Philosophy, for example, Descartes defines “thought” (cogitationis) as “everything which we are aware of as happening within us, in so far as we have awareness of it. Hence, thinking is to be identified here not merely with understanding, willing and imagining, but also with sensory awareness” (Descartes 1984: 195). But whereas Descartes’s equation between sensory awareness and thought arguably just amounts to a stipulative definition of the term cogitationis, Dennett seems to maintain that conscious states are themselves constituted by the subject’s beliefs or judgments about them. Yet if experiences are constituted by our judgments about them, then those judgments must be either false or infallible. They will be false whenever they purport to be about an experience not constituted by a judgment, for the theory tells us there are no such things, and they will be incorrigible inasmuch as they in fact turn out to be about themselves, which renders them self-validating, hence infallible. On Dennett’s theory, then, judgments about experience must either fail to refer, and thus be false, or refer to themselves, and thus be self-certifying. In any event, for Dennett, judgments about experience cannot be about experience in the robust sense of there being such a thing as experience distinct from our judgments about it. Dennett is often criticized for denying the existence of consciousness, and he has often denied denying it. Disagreement of this sort can arise, it seems to me, only because his view equivocates between on the one hand a subtle and plausible challenge to a cluster of traditional assumptions about consciousness, and on the other hand a boldly counterintuitive conjecture that challenges not just expert opinion but also common sense, indeed manifest appearance (assuming there is such a thing). As Dennett himself says, “I will soon be mounting radical challenges to everyday thinking,” for his theory “is initially deeply counterintuitive” (Dennett 1991: 45, 17). More precisely, when his imagined interlocutor objects that “there seems to be” more to phenomenology than mere judgments about how things are, Dennett replies, “Exactly! There seems to be phenomenology....But it does not follow from this Dennett on seeming 101 undeniable, universally attested fact that there really is phenomenology” (Dennett 1991: 366). Finally, referring to the various labels philosophers have attached to the phenomenal qualities of experience (“raw feels,” “sensa,” “qualia”) Dennett writes, “In the previous chapter I seemed to be denying that there are any such properties, and for once what seems so is so. I am denying that there are any such properties. But...I agree wholeheartedly that there seem to be qualia” (Dennett 1991: 372). What does it mean to deny “that there are any such properties?” Dennett’s denial of the reality of qualia, it seems to me, equivocates between a weaker and a stronger pair of assertions. The weaker pair are (in my words): (1) that the qualitative aspects of experience are neither discrete objects internal to the mind nor fully determinate properties of consciousness observable and describable in terms comparable to those in which we observe and describe external objects and their properties; and (2) that there is no sharp boundary, only a gradual difference, between the qualitative aspects of experience and the propositional contents of attitudes such as belief or judgment. These are by no means trivial claims. But although they depart from traditional philosophical and psychological orthodoxy, I want to suggest, they pose no threat to phenomenology. They certainly imply nothing like eliminativism with respect to phenomenal consciousness itself. At best, they remind us to resist the temptation to assimilate our understanding of experience to our understanding of the world itself and its objective features. Now compare those two weaker claims with the following stronger claims (again in my words): (3) that people often suppose that conscious experience has qualitative features of its own, distinct from the qualities of the objects of our awareness – but they are mistaken, for there are no such qualities; and (4) that people suppose that things are given in perception and really seem a certain way, as distinct from and often as the basis of their judgments about them – but again they are mistaken, for perception is itself just a form of thought or judgment. Does Dennett give us any reason to believe theses (3) and (4), over and beyond (1) and (2)? As readers of Consciousness Explained will recall, experiments conducted by Paul Kolers, prompted by questions from Nelson Goodman, show that subjects who are shown a red spot, followed by a displaced green spot, followed by another red spot in the original location, report seeing one spot rapidly moving back and forth and changing color about halfway between the two points (Kolers and von Grünau 1976). How, Goodman reasonably asks, are the subjects able “to fill in the spot at the intervening place–times along a path running from the first to the second flash before that second flash occurs?” (Goodman 1978: 73; Dennett 1991: 114ff). Dennett considers two hypotheses: either we concoct false memories of having seen the spot change color, though in fact we had no immediate sensory awareness of the change, or we really do have a genuine, albeit delayed, sensory awareness of the light moving continuously and changing color. Dennett’s thesis is that it is impossible in principle to decide between these two hypotheses. It’s not just that we lack sufficient data to determine which one is true, but rather that there is no empirical difference between the two descriptions. The intuition that one must be correct to the exclusion of the other, he thinks, is part of the crippling legacy of the notion of a “cartesian theater,” a single discrete place in the mind or brain where consciousness finally happens, subsequent to its physical causes and preceding its physical effects. The Multiple Drafts model, by contrast, 102 T. Carman deliberately blurs the line between putative events of consciousness and the various cognitive attitudes we ordinarily regard as higher-order processes responding to, but distinct from, phenomenal awareness. There is no difference, he thinks, between how things seem to us and how we think they seem. He concedes that it seems to us as if there is a difference between what we might call real seemings and merely apparent seemings, but this seeming is itself no more a real seeming than any other, prior to and independent of our judgment; it is instead just our (poor) judgment concerning what we (wrongly) take to be the purity and plenitude of phenomenal consciousness, distinct from all our psychological and folk-psychological judgments about it. “There seem to be qualia, because...it seems that what is in here can’t just be the judgments we make when things seem colored to us” (Dennett 1991: 372). The conclusion Dennett wants to draw, then, is that there is no perceptual or sensory seeming at all, distinct from the conceptual contents of judgments we make about how things seem to us. There is no distinction to be drawn, he thinks, between how things seem to us, and how we judge that they seem; seemings and judgings collapse into a single cognitive effect: Consider how natural is the phrase ‘I judged it to be so, because that’s the way it seemed to me.’ Here we are encouraged to think of two distinct states or events: the seeming-a-certain-way and a subsequent (and consequent) judgingthat-it-is-that-way....There must be ‘evidence presented’ somewhere, if only in a Stalinesque show trail, so that the judgment can be caused by or grounded in that evidence. Some people presume that this intuition is supported by phenomenology. They are under the impression that they actually observe themselves judging things to be such as a result of those things seeming to them to be such. No one has ever observed any such thing ‘in their phenomenology’ because such a fact about causation would be unobservable (as Hume noted long ago). (Dennett 1991: 133) It is worth pointing out that Dennett’s parenthetical appeal to Hume here is misleading. Hume insisted on the unobservability of causal necessity, not mere causal regularity. I can see the movement of the eight ball “constantly conjoined” with the impact of the cue ball; what I cannot see is the impact of the cue ball making the eight ball move. So too, I can observe, just as Hume took himself to have observed, perceptions conjoined with but not necessitating judgments. What about the intellectualist thesis itself, namely, that perceptual content is constituted by acts of thought or judgment? Merleau-Ponty seems almost to have had a premonition of Dennett’s view in Phenomenology of Perception when he criticizes intellectualism for in effect obliterating the phenomenon it purports to analyze. Intellectualist accounts of perception, he argues, fail to acknowledge the embodiment and environmental situatedness of experience, reducing perceptual content to the abstract, free-floating judgments of a disembodied subject: Perception is thus thought about perceiving. Its incarnation furnishes no positive characteristic that has to be accounted for, and its haecceity is simply its own ignorance of itself. Reflective analysis becomes a purely regressive doctrine, according to which every perception is just confused intellection, every determination a negation. It thus does away with all problems except one: Dennett on seeming 103 that of its own beginning. The finitude of a perception, which gives me, as Spinoza put it, ‘conclusions without premises’, the inherence of consciousness in a point of view, all this reduces to my ignorance of myself, to my negative power of not reflecting. But that ignorance, how is it itself possible? (MerleauPonty [1945] 2002: 44) Intellectualist accounts of perception like Dennett’s, not only rely on implausible phenomenologies, but lapse into incoherence by offering a theory of something the existence of which the theory itself cannot acknowledge. Yet if sensory awareness is just ignorance or illusion, it must at least be the kind of ignorance or illusion that a theory of sensory awareness is obliged to recognize and describe. Does Dennett make a convincing case for the intellectualist position? It is not hard to see how the two weaker claims, (1) and (2), gain momentum from what he says. There are often no good answers to questions about the precise qualities of our perceptual experience. How much bigger does the moon look on the horizon than at its zenith? By how much do the Müller-Lyer lines differ in length? At what angle do the lines in Zöllner’s illusion appear to diverge? Which object do you see just inside the outer boundary of your visual field? What does the edge of your visual field look like? And of course we do sometimes draw a merely verbal distinction between how things seem and how we judge them to be. To say that the price of something “seems” high to us is often just to say that we judge it to be high, and it can indeed be pseudoexplanatory to say that we judge it that way because that’s how it strikes us. It is also clear that our beliefs trickle down and color our perceptual experience, just as our perceptual experience reaches up and shapes our beliefs. But common sense knows this. Squeamish eaters are a reminder that the taste of food is highly sensitive to what you think you are ingesting, just as we all know that pain is made more intense by fear and the expectation of injury. Eagerly expecting to see your friend in the airport can produce multiple false sightings, since every remotely resembling physical trait tends to leap out and “catch your eye.” So too, a language will look and sound very different to you depending on whether or not you understand it: foreign speech sounds like a continuous stream of noises; intelligible speech sounds like a series of discrete words. What about Dennett’s more radical claims, (3) and (4)? What, specifically, does the phi movement in Kolers’s experiment tell us about the reality of phenomenal consciousness and its distinctness from judgment in general? Dennett may be right that there is nothing to choose between a priori in the two claims in this case: on the one hand, that the subjects literally see the spot seeming to move and change gradually from red to green by “filling in” the missing stages in its journey, after which the doctored evidence reaches consciousness intact; and on the other hand, that they instead concoct false judgments and memories of having seen its continuous transition, though in fact they did not. But can Dennett plausibly extend his skepticism beyond this special case? Two points are worth noting. First, it is worth remembering that these experiments involve perceptions (or misperceptions) occurring on a scale of only fractions of a second. If we turn our attention to a wider temporal framework, it becomes much harder to swallow the idea that there is no difference in principle between immediate sense experiences and memories or judgments. Even if our present sensory awareness blurs gradually into a 104 T. Carman retention of the immediate past, it does not follow that there is no difference at all between perceptual experience and processes such as memory or judgment. Why should we generalize ambiguities on the micro scale to the macro perceptual world in which we readily distinguish such psychological operations? As Merleau-Ponty says, “Ordinary experience draws a clear distinction between sense experience and judgment.” However, “This distinction disappears in intellectualism, because judgment is everywhere pure sensation is not, which is to say everywhere. The testimony of phenomena will therefore everywhere be impugned” (Merleau-Ponty [1945] 2002: 39). Hasty generalizations from microstructures and a contempt for the phenomena are as ill advised in phenomenology as they are in physics, and we have no more reason to abandon the distinction between perception and judgment in normal cases in deference to isolated experimental effects than Sir Arthur Eddington had to infer from the vast stretches of empty space between atoms that his desk was not a perfectly solid object. Solid oak desks are solid physical objects, and the proportion of intervening space at the atomic level is irrelevant to that fact. Second, conversely, if the phi phenomena in Kolers’s experiment seem to undermine any sharp distinction between immediate sensory awareness and shortterm memory and judgment, surely the conclusion to draw is that such commonsense psychological categories, which figure so prominently in everyday life, fail to apply in any obvious way on a very small scale and in highly artificial experimental conditions. This might sound like Dennett’s own conclusion, namely, that common sense is a notoriously unreliable guide when we set out to construct a sound scientific theory of consciousness. But my point is different. It is not that the results of such experiments reveal for the first time the real facts about consciousness, rendering the categories of our ordinary understanding obsolete. Rather, they serve to point up qualitative indeterminacies that specify lower spatiotemporal thresholds beneath which some ordinary concepts pertaining to perception fail to get a grip. That such concepts have only a limited range of application is hardly surprising. If we are unable to choose between the two apparently conflicting hypotheses in the case of perceptions of very quickly flashing spots of light, then, it is not because they are equally good when extended to the general case, as Dennett seems to suggest, but because they are equally bad. Neither hypothesis seems particularly plausible, even in the experiment as Dennett describes it. On the one hand, to say that the subjects had distinct visual sensations of a red spot appearing, moving to one side, turning green at a single discrete instant at a constant rate at every point on its path, reversing direction, moving back, instantaneously turning red again perfectly gradually, then disappearing, would obviously be to overstate their visual acuity. On the other hand, to deny that the subjects saw any continuity, movement, or color change at all is implausible, and it would be absurd to suggest that no one ever really sees continuity, movement, or color change in phi phenomena. To bite that bullet would surely be to deny the phenomenon you’re pretending to explain. Phi movement occurring in an isolated stimulus within a fraction of a second is an interesting effect, then, but I think it reveals nothing very important about the application of our ordinary concepts of perception, memory, and judgment under normal conditions; at best, it points up a kind of boundary condition for the Dennett on seeming 105 application of those concepts. Far from showing that there is no difference in general between seeing and judging, Kolers’s experiment shows only that our ordinary notions of seeing and judging break down with appearances on a very small scale. An interesting result, but hardly a reason to deny the existence of qualitative sensory experience as distinct from judgment wholesale, as Dennett does. Denying that there is any distinction at all between phenomenal seemings and cognitive judgings is a drastic conclusion to draw from the evidence. We should not infer from a few ambiguous cases in highly artificial conditions that there is never a difference between how things seem to me and how I judge them to be, or indeed how I judge them to seem, as if those distinctions were just conceptual or verbal confusions, like the distinction between pain and the feeling of pain. What is especially striking about Dennett’s proclaimed “disqualification of qualia,” however, is his admission that “There seems to be phenomenology.” This apparent concession sounds conciliatory at first blush: “I wholeheartedly agree that there seem to be qualia,” he says (Dennett 1991: 366, 372). But in fact it is no concession at all to our ordinary understanding of perceptual seeming, and his agreement with his phenomenological interlocutor is not as wholehearted as it sounds. For it sounds superficially as if Dennett is admitting that, when it comes to the seeming of seeming, in this case at least, we have a genuine nonjudgmental seeming on our hands, a “real” seeming. But this is not what he means. He means only that we are all initially prone to judge that things really seem to us a certain way, independent of our judgment. What he is acknowledging is not a real seeming at all, but rather what he regards as a quasitheoretical intuition (not a Kantian kind of intuition, but an “intuition” in the philosopher’s sense of a naive judgment). What he grants the phenomenologist, in short, is not the phenomena, only reflective judgments about the phenomena. But this begs the question, for whether there can be a difference between our judgments about our experience and that experience itself is precisely what is at issue between Dennett and phenomenology, and for that matter between Dennett and common sense. Dennett recognizes no difference between perceptual phenomena and what we report about them upon reflection. This is the methodological point of heterophenomenology, which regards experiential reports as just so much behavioral evidence to add to the mix of empirical evidence for any theory of consciousness. Dennett chides “the Husserlian school(s) of Phenomenology” for the method of epoché, or “bracketing,” which, he says, “excuses the investigator from all inquiry, speculative or otherwise, into the underlying mechanisms” of consciousness (Dennett 1998: 235). As a matter of historical record, most of the major representatives of that movement rejected the epoché as a phenomenologically unmotivated dogma, and what Dennett is really chiding them for is the fact that they all took the perceptual phenomena seriously, as distinct from the judgments we form about them on reflection. I believe Dennett ignores that distinction at his peril. Indeed, renouncing the dogma of incorrigibility, as Dennett does, means recognizing, as phenomenologists have, the various ways in which we can be, and often are, mistaken in our judgments concerning the structures and qualities of our own experience. Indeed, we can know we are mistaken precisely because such judgments are possible. Good phenome- 106 T. Carman nology, like good observation and description of any kind, captures appearances fresh and pulls our attention away from long-standing theoretical prejudices and the ingrained reflective habits of common sense. Good phenomenology, if there is to be such a thing, must be committed to getting it right about how things actually show up for us, prior to our reflecting and theorizing about them.
