In this paper I begin by explaining the concept of supervenience. I then describe the problem of qualia and explain why qualia are a problem for physicalist theories of the mind. Next, I outline the zombie argument and explain Chalmers' attempt to use it as an argument for the conclusion that qualia do not logically supervene on the physical. My goal is to show that the supposed conceivability of zombies does not offer any serious refutation of physicalist theories of the (...) mind. (shrink)

My central claim is that philosophers of mind have failed to take adequate account of empirical evidence regarding human consciousness and vision. Experiments on split-brain patients over the past fifty years reveal consciousness in both cerebral hemispheres. I claim specifically that (a) consciousness in the right hemisphere is inherited from our animal ancestors; (b) consciousness in the left hemisphere arose during human evolution in association with language; and (c) the existence of both forms of consciousness provides the best explanation for (...) many aspects of normal human experience. Evidence for two cortical visual pathways in the human brain has been expanding for twenty years. The ventral pathway is specialised for object identification, and the dorsal pathway for the control of actions in respect of those objects. The evidence has been challenged by those who have failed (a) to distinguish between the visual pathways themselves and processes served by the pathways, and (b) to recognise the specific circumstances in which actions draw on one pathway. I claim that in the left hemisphere only the ventral pathway reaches consciousness. The combination of two visual pathways with two centres of consciousness challenges traditional views about perception. I claim that (a) perception is distinct from seeing; (b) perception is limited to the left hemisphere; and (c) the parallel process in the right hemisphere is associated with the emotions. The presence of two centres of consciousness challenges traditional views on the unity of consciousness and on personhood; but it also offers an explanation for conflicting views on the emotions and the existence of self-deception. I distinguish my claims about human consciousness from the Dual Systems (or Two Minds) Theory. Although there are superficial parallels, the latter theory denies that both systems/minds are conscious, and takes no account of the specialisation of the cerebral hemispheres revealed by experiments on split-brain patients. I conclude that philosophy must incorporate empirical evidence if it is to avoid claims of irrelevance. (shrink)

The higher order approach to consciousness attempts to build a theory of consciousness from the insight that a conscious state is one that the subject is conscious of. There is a well-known objection1 to the higher order approach, a version of which is fatal. Proponents of the higher order approach have realized that the objection is significant. They have dealt with it via what David Rosenthal calls a “retreat” (2005b, p. 179) but that retreat fails to solve the problem.

This is a bibliography of books and articles on consciousness in philosophy, cognitive science, and neuroscience over the last 30 years. There are three main sections, devoted to monographs, edited collections of papers, and articles. The first two of these sections are each divided into three subsections containing books in each of the main areas of research. The third section is divided into 12 subsections, with 10 subject headings for philosophical articles along with two additional subsections for articles in cognitive (...) science and neuroscience. Of course the division is somewhat arbitrary, but I hope that it makes the bibliography easier to use. This bibliography has first been compiled by Thomas Metzinger and David Chalmers to appear in print in two philosophical anthologies on conscious experience . From 1995 onwards it has been continuously updated by Thomas Metzinger, and now is freely available as a PDF-, RTF-, or HTML-file. This bibliography mainly attempts to cover the Anglo-Saxon and German debates, in a non-annotated, fully formatted way that makes it easy to "cut and paste" from the original file. To a certain degree this bibliography also contains items in other languages than English and German - all submissions in other languages are welcome. Last update of current version: July 13th, 2001.

Some philosophers have conflated functionalism and computationalism. I reconstruct how this came about and uncover two assumptions that made the conflation possible. They are the assumptions that (i) psychological functional analyses are computational descriptions and (ii) everything may be described as performing computations. I argue that, if we want to improve our understanding of both the metaphysics of mental states and the functional relations between them, we should reject these assumptions.

Working from a naïve-realist perspective, I examine first-person knowledge of one's perceptual experience. I outline a naive-realist theory of how subjects acquire knowledge of the nature of their experiences, and I argue that naive realism is compatible with moderate, substantial forms of first-person privileged access. A more general moral of my paper is that treating “success” states like seeing as genuine mental states does not break up the dynamics that many philosophers expect from the phenomenon of knowledge of the mind.

Arguably no concept is more fundamental to science than that of causality, for investigations into cases of existence, persistence, and change in the natural world are largely investigations into the causes of these phenomena. Yet the metaphysics and epistemology of causality remain unclear. For example, the ontological categories of the causal relata have been taken to be objects (Hume 1739), events (Davidson 1967), properties (Armstrong 1978), processes (Salmon 1984), variables (Hitchcock 1993), and facts (Mellor 1995). (For convenience, causes and effects (...) will usually be understood as events in what follows.) Complicating matters, causal relations may be singular (Socrates’s drinking hemlock caused Socrates’s death) or general (Drinking hemlock causes death); hence the relata might be tokens (e.g., instances of properties) or types (e.g., types of events) of the category in question. Other questions up for grabs are: Are singular causes metaphysically and/or epistemologically prior to general causes or vice versa (or neither)? What grounds the intuitive asymmetry of the causal relation? Are macro-causal relations reducible to micro-causal relations? And perhaps most importantly: Are causal facts (e.g., the holding of causal relations) reducible to non-causal facts (e.g., the holding of certain spatiotemporal relations)? (shrink)

Few contemporary researchers in psychology, philosophy, and the cognitive sciences have any doubt about whether mental phenomena occur without being conscious. There is extensive and convincing clinical and experimental evidence for the existence of thoughts, desires, and related mental states that aren’t conscious. We characterize thoughts, desires, intentions, expectations, hopes, and many other mental states in terms of the things they are about and, more fully, in terms of their content, as captured by a sentence nominalization, such as a clause (...) beginning with the word ‘that’. The philosophical literature follows Franz Brentano’s adaptation of Thomist terminology in referring to all such states as intentional states. But there is another type of mental phenomena, which lack intentionality and whose mental nature consists instead of some qualitative feature. These states include bodily sensations, such as aches and pains, and perceptual states, such as visual sensations of color and tactile sensations of heat and cold. And these states all exhibit some mental quality or another, such as the mental quality distinctive of pain or the mental quality of red or blue.1 And even theorists who acknowledge that intentional states can and do occur without being conscious have sometimes insisted that qualitative states cannot. There is, according to these theorists, nothing to a state’s being qualitative or exhibiting some mental quality unless that state is conscious – unless it is, as we might metaphorically say, “lighted up”. It’s striking that Freud himself seems to have adopted this double standard toward the two types of mental state. In his metapsychological paper, “The Unconscious”, for example, he writes that “all the categories which we employ to describe conscious mental acts, such as ideas, purposes, resolutions, and so forth, can be applied to [unconscious mental occurrences]” (Freud 1915e, p. 168). But he seems here to have in.. (shrink)

Quite a few recent models are rapidly introducing new concepts describing different levels of consciousness. This situation is getting confusing because some theorists formulate their models without making reference to existing views, redundantly adding complexity to an already difficult problem. In this paper, I present and compare nine neurocognitive models to highlight points of convergence and divergence. Two aspects of consciousness seem especially important: perception of self in time and complexity of self-representations. To this I add frequency of self-focus, amount (...) of self-related information, and accuracy of self-knowledge. Overall, I conclude that many novel concepts (e.g., reflective, primary, core, extended, recursive, and minimal consciousness) are useful in helping us distinguish between delicate variations in consciousness and in clarifying theoretical issues that have been intensely debated in the scientific literature—e.g., consciousness in relation to mirror self-recognition and language.

According to rich views of consciousness (e.g., James, Searle), we have a constant, complex flow of experience (or 'phenomenology') in multiple modalities simultaneously. According to thin views (e.g., Dennett, Mack and Rock), conscious experience is limited to one or a few topics, regions, objects, or modalities at a time. Existing introspective and empirical arguments on this issue (including arguments from 'inattentional blindness') generally beg the question. Participants in the present experiment wore beepers during everyday activity. When a beep sounded, they (...) were to take note of the conscious experience, if any, they were having at the last undisturbed moment immediately prior to the beep. Some participants were asked to report any experience they could remember. Others were asked simply to report whether there was visual experience or not (and if so, what it was). Still others were asked about experience in the far right visual field, or tactile experience, or tactile experience in the left foot. A majority of participants in the full experience and the visual conditions reported visual experience in every single sample. Tactile and peripheral visual experience were reported less often. However, the proper interpretation of these results is uncertain. (shrink)

How can we disentangle the neural basis of phenomenal consciousness from the neural machinery of the cognitive access that underlies reports of phenomenal consciousness? We can see the problem in stark form if we ask how we could tell whether representations inside a Fodorian module are phenomenally conscious. The methodology would seem straightforward: find the neural natural kinds that are the basis of phenomenal consciousness in clear cases when subjects are completely confident and we have no reason to doubt their (...) authority, and look to see whether those neural natural kinds exist within Fodorian modules. But a puzzle arises: do we include the machinery underlying reportability within the neural natural kinds of the clear cases? If the answer is ‘Yes’, then there can be no phenomenally conscious representations in Fodorian modules. But how can we know if the answer is ‘Yes’? The suggested methodology requires an answer to the question it was supposed to answer! The paper argues for an abstract solution to the problem and exhibits a source of empirical data that is relevant, data that show that in a certain sense phenomenal consciousness overflows cognitive accessibility. The paper argues that we can find a neural realizer of this overflow if assume that the neural basis of phenomenal consciousness does not include the neural basis of cognitive accessibility and that this assumption is justified by the explanations it allows.

Explaining the mind by building machines with minds runs into the other-minds problem: How can we tell whether any body other than our own has a mind when the only way to know is by being the other body? In practice we all use some form of Turing Test: If it can do everything a body with a mind can do such that we can't tell them apart, we have no basis for doubting it has a mind. But what is (...) "everything" a body with a mind can do? Turing's original "pen-pal" version (the TT) only tested linguistic capacity, but Searle has shown that a mindless symbol-manipulator could pass the TT undetected. The Total Turing Test (TTT) calls for all of our linguistic and robotic capacities; immune to Searle's argument, it suggests how to ground a symbol manipulating system in the capacity to pick out the objects its symbols refer to. No Turing Test, however, can guarantee that a body has a mind. Worse, nothing in the explanation of its successful performance requires a model to have a mind at all. Minds are hence very different from the unobservables of physics (e.g., superstrings); and Turing Testing, though essential for machine-modeling the mind, can really only yield an explanation of the body.

As is widely appreciated and easily demonstrated, the notion that we are essentially experiential (or conscious) beings has a good deal of appeal; what is less obvious, and more controversial, is whether it is possible to devise a viable account of the self along such lines within the confines of a broadly naturalistic metaphysical framework. There are many avenues to explore, but here I confine myself to outlining the case for one particular approach. I suggest that we should think of (...) ourselves (or our essential cores) as being composed of experience-producing systems, and that such systems belong to the same self when they have the capacity to contribute to unified streams of consciousness. The viability of this proposal rests in turn on a particular conception of the structure of consciousness, both at and over time; this conception is defended in the first part of the paper..

It is often said that some kind of peripheral (or inattentional) conscious awareness accompanies our focal (attentional) consciousness. I agree that this is often the case, but clarity is needed on several fronts. In this paper, I lay out four distinct theses on peripheral awareness and show that three of them are true. However, I then argue that a fourth thesis, commonly associated with the so-called "self-representational approach to consciousness," is false. The claim here is that we have outer focal (...) consciousness accompanied often (or even always) by inner peripheral (self-)awareness. My criticisms stem from both methodological and phenomenological considerations. In doing so, I offer a diagnosis as to why the fourth thesis has seemed true to so many and also show how the so-called "transparency of experience," frequently invoked by representationalists, is importantly relevant to my diagnosis. Finally, I respond to several objections and to further attempts to show that thesis four is true. What emerges is that if one wishes to hold that some form of self-awareness accompanies all outer-directed conscious states, one is better off holding that such self-awareness is itself unconscious, as is held for example by standard higher-order theories of consciousness.

Human consciousness usually displays a striking unity. When one experiences a noise and, say, a pain, one is not conscious of the noise and then, separately, of the pain. One is conscious of the noise and pain together, as aspects of a single conscious experience. Since at least the time of Immanuel Kant (1781/7), this phenomenon has been called the unity of consciousness . More generally, it is consciousness not of A and, separately, of B and, separately, of C, but (...) of A-and-B- and-C together, as the contents of a single conscious state. (shrink)

. When I have a conscious experience of the sky, there is a bluish way it is like for me to have that experience. We may distinguish two aspects of this "bluish way it is like for me": the bluish aspect and the for-me aspect. Let us call the bluish aspect of the experience its qualitative character and the for-me aspect its subjective character . What is this elusive for-me-ness, or subjective character , of conscious experience? In this paper, I (...) examine six different attempts to account for subjective character in terms of the functional and representational properties of conscious experiences. After arguing against the first five, I defend the sixth. (shrink)

One of the promising approaches to the problem of consciousness has been the Higher-Order Monitoring Theory of Consciousness. According to the Higher-Order Monitoring Theory, a mental state M of a subject S is conscious iff S has another mental state, M*, such that M* is an appropriate representation of M. Recently, several philosophers have developed a Higher-Order Monitoring theory with a twist. The twist is that M and M* are construed as entertaining some kind of constitutive relation, rather than being (...) logically independent of each other. We may call this the Same-Order Monitoring Theory of Consciousness. In this paper, I discuss the nature of the Same-Order Monitoring Theory and argue for its superiority over the more traditional Higher-Order Monitoring Theory. (shrink)

One of the distinctive properties of conscious states is the peculiar self- awareness implicit in them. Two rival accounts of this self-awareness are discussed. According to a Neo-Brentanian account, a mental state M is conscious iff M represents its very own occurrence. According to the Higher-Order Monitoring account, M is merely accompanied by a numerically distinct representation of its occurrence. According to both, then, M is conscious in virtue of figuring in a higher-order content. The disagreement is over the question (...) whether the higher-order content is carried by M itself or by a differ- ent state. While the Neo-Brentanian theory is phenomenologically more attractive, it is often felt to be somewhat mysterious. It is argued that the difference between the Neo- Brentanian and Higher-Order Monitoring theories is smaller and more empirical than may initially seem, and that the Neo-Brentanian theory can be readily demystified. These considerations make it prima facie preferable to the Higher-Order Monitoring theory. (shrink)

Journal of Mind and Behavior 28 no. 2 , pp. 135-156. The self-prompting theory of consciousness holds that conscious perceptual experience occurs when non-routine perceptual data prompt the activation of a plan in an executive control system that monitors perceptual input. On the other hand, routine, non-conscious perception merely provides data about the world, which indicatively describes the world correctly or incorrectly. Perceptual experience instead involves data that are about the perceiver, not the world. Their function is that of imperatively (...) prompting the perceiver herself to do something (hence. (shrink)

This dissertation may be divided into two parts. The first is about the Extended Gricean Model of information transmission. This model, introduced here, is meant to better explain how humans communicate and understand each other. It has been developed to apply to cases that were left unexplained by the two main models of communication found in contemporary philosophy and linguistics, i.e. the Gricean (pragmatic) model and the code (semantic) model. I discuss cases involving emotional reactions, ways of clothing, speaking, or (...) behaving that are not intended for communication but whose effects on the audience are controllable to some extent. I show why prevailing code and Gricean models cannot explain them and how my Extended Gricean Model does. The second part of the dissertation is about what emotional signs mean, in various senses of the term ‘mean'. I review existing theories of meaning and see how they apply to emotional signs, i.e. signs which give us information about the affective state of the sign producer. (shrink)

En este artículo, examino algunas características importantes de las teorías de conciencia y autoconciencia de Brentano y Rosenthal. En particular, analizo la distinción entre estados mentales y estados conscientes, y la cuestión relacionada con de determinar si todos los estados mentales pueden convertirse en estados conscientes. Interpreto la teoría de Brentano como una teoría de la mente de un nivel que está de acuerdo con la fusión cartesiana entre los estados mentales y la conciencia. Argumento que los problemas que surgen (...) de la posición de Brentano son, hasta cierto punto, superados por una teoría de orden superior, de modo que la posición de Rosenthal es más precisa. Sin embargo, estoy en desacuerdo con ambos en la interpretación de la consciencia de un estado mental como autoconciencia. Desarrollo los fundamentos de una teoría basada en la primacía del organismo y su mundo vital, y de la experiencia consciente como la forma superior de la vida mental, que tiene, sin embargo, sus raíces en la compleja red de estados mentales que son no estados conscientes.In this paper, I examine some important features of Brentano’s and Rosenthal’s theories of consciousness and self-consciousness. In particular, I discuss the distinction between mental states and conscious states, and the related question of determining whether all mental states can become conscious states. I interpret Brentano’s theory as a one-level theory of mind which is in keeping with the Cartesian conflation between mental states and conscious-ness. I argue that the problems arising from Brentano’s position are to a certain extent surpassed by a higher-order theory, so that Rosenthal’s position is more accurate. Nevertheless, I disagree with both in the construal of the consciousness of a mental state as self-consciousness. I develop then the fundamentals for a theory based on the primacy of the organism and its vital world, and of conscious experience as the higher form of mental life, which has, however, its roots in the complex net of mental states which are not conscious states.

I argue that a study of the Nicomachean Ethics and of the Parva Naturalia shows that Aristotle had a notion of attention. This notion captures the common aspects of apparently different phenomena like perceiving something vividly, being distracted by a loud sound or by a musical piece, focusing on a geometrical problem. For Aristotle, these phenomena involve a specific selectivity that is the outcome of the competition between different cognitive stimuli. This selectivity is attention. I argue that Aristotle studied the (...) common aspects of the physiological processes at the basis of attention and its connection with pleasure. His notion can explain perceptual attention and intellectual attention as voluntary or involuntary phenomena. In addition, it sheds light on how attention and enjoyment can enhance our cognitive activities. (shrink)

Reply to eight critical reviews of my paper "Franz Brentano and Higher-Order Theories of Consciousness" in the same issue of the journal Argumentos.

What is it that makes a mental state conscious? Recent commentators have proposed that for Kant, consciousness results from differentiation: A mental state is conscious insofar as it is distinguished, by means of our conceptual capacities, from other states and/or things. I argue instead that Kant’s conception of state consciousness is sensory: A mental state is conscious insofar as it is accompanied by an inner sensation. Interpreting state consciousness as inner sensation reveals an underappreciated influence of Crusius on Kant’s view, (...) solves some long-standing puzzles concerning Kant’s difficult doctrine of self-affection, and sheds light on his theory of inner experience.

According to a widely held physicalist view, consciousness is identical with some physical or functional phenomenon just as liquidity is identical with loose molecular connection. To many of us, this claim about consciousness seems more problematic than the claim about liquidity. To many—including many physicalists—the identification of consciousness with some physical phenomenon even seems “absurd” or “crazy”. A full defence of physicalism should explain why the allegedly correct hypothesis comes across this way. If physicalism is true and we have reason (...) to accept it, why does it seem “absurd”? One possibility is that this is fully explained by the fact that we have an erroneous understanding of consciousness or its physical basis. This explanation is embraced by few if any physicalists. It is rejected by many, including proponents of the “phenomenal concept strategy”, which lately has become the dominant strategy for defending physicalism. But the “error explanation” is clearly the most plausible explanation that is available to physicalists. So this paper argues. (shrink)

Emotional states of consciousness, or what are typically called emotional feelings, are traditionally viewed as being innately programed in subcortical areas of the brain, and are often treated as different from cognitive states of consciousness, such as those related to the perception of external stimuli. We argue that conscious experiences, regardless of their content, arise from one system in the brain. On this view, what differs in emotional and non-emotional states is the kind of inputs that are processed by a (...) general cortical network of cognition, a network essential for conscious experiences. Although subcortical circuits are not directly responsible for conscious feelings, they provide non-conscious inputs that coalesce with other kinds of neural signals in the cognitive assembly of conscious emotional experiences. In building the case for this proposal, we defend a modified version of what is known as the higher-order theory of consciousness. (shrink)

Higher-Order Perception (HOP) theories in the philosophy of mind are offered as explanations of what it is that makes a mental state a conscious state. According to HOP, a mental state is conscious just in case it is itself represented in a quasi-perceptual way by an internal monitor or scanning device. We start with one of the more popular objections to HOP and a seemingly innocuous concession to it: identifying the internal monitor with the faculty of attention. We show how (...) this concession undermines HOP. (shrink)

Relative blindsight is said to occur when different levels of subjective awareness are obtained at equality of objective performance. Using metacontrast masking, Lau and Passingham reported relative blindsight in normal observers at the shorter of two stimulus-onset asynchronies between target and mask. Experiment 1 replicated the critical asymmetry in subjective awareness at equality of objective performance. We argue that this asymmetry cannot be regarded as evidence for relative blindsight because the observers’ responses were based on different attributes of the stimuli (...) at the two SOAs. With an invariant criterion content , there was no asymmetry in subjective awareness across the two SOAs even though objective performance was the same. Experiment 3 examined the effect of criterion level on estimates of relative blindsight. Collectively, the present results question whether metacontrast masking is a suitable paradigm for establishing relative blindsight. Implications for theories of consciousness are discussed.

In the sixth century a.d., in a debate with the Buddhists about the nature of Self, the well-known Naiyāyika Uddyotakara declared that there is no need prove that the Self or what is referred to by the pronoun “I” exists, for on that score there cannot be any significant disagreement.1 It is only this or that specific metaphysical nature of the self that is the subject of controversy. To limit the scope of the debate at issue here, we employ the (...) same strategy.

I propose a strategy for a metaphysical reduction of perceived color, that is, an identification of perceived color with properties characterizable in non-qualitative terms. According to this strategy, a description of visual experience of color, which incorporates a description of the appearance of color, is a reference-fixing description. This strategy both takes color appearance seriously in its primary epistemic role and avoids rendering color as metaphysically mysterious. I’ll also argue that given this strategy, a plausible account of perceived color claims (...) that colors are physical properties of physical objects. (shrink)

In this paper I outline and defend an introspectionist account of authoritative self-knowledge for a certain class of cases, ones in which a subject is both thinking and thinking about a current, conscious thought. My account is distinctive in a number of ways, one of which is that it is compatible with the truth of externalism.

Relationalism claims that the phenomenal character of perception is constituted by the obtaining of a non-representational psychological relation to mind-independent objects. Although relationalism provides what seems to be the most straightforward and intuitive account of how experience strikes us introspectively, it is very often believed that the argument from hallucination shows that the view is untenable. The aim of this thesis is to defend relationalism against the argument from hallucination. The argument claims that the phenomenal character of hallucination and perception (...) deserves the same account, and that relationalism cannot be true for hallucinations, therefore relationalism must be rejected. This argument relies on the Indiscriminability Principle, the claim that two experiences that are introspectively indiscriminable from each other have the same phenomenal character. Before assessing the plausibility of this principle, I first consider and dismiss versions of the argument which wouldn’t depend on IND. Although widely accepted, no satisfactory support for IND has been presented yet. In this thesis I argue that defending IND requires that we understand the notion of ‘indiscriminability’ employed in IND in an impersonal sense. I then identify what underwrites IND: the intuition that, in virtue of its superficiality, the nature of a phenomenal character must be accessible through introspection, together with the claim that it is not possible to deny IND without denying the superficiality of phenomenal characters too. I argue that the relationalist can deny IND while preserving the superficiality of phenomenal characters. This can be done by adopting a negative view of hallucination and an account of introspection whereby the phenomenal character doesn’t exist independently of one’s introspective awareness of it and where having introspective access to our experience depends on our perceptual access to the world.

This article investigates Hume's account of mental transparency. In this article, I will endorse Qualitative Transparency – that is, the thesis that we cannot fail to apprehend the qualitative characters of our current perceptions, and these apprehensions cannot fail to be veridical – on the basis that, unlike its competitors, it is both weak enough to accommodate the introspective mistakes that Hume recognises, and yet strong enough to make sense of his positive employments of mental transparency. Moreover, Qualitative Transparency is (...) also philosophically satisfying in providing good philosophical reason for why the mental states that are incorrigible should in fact be so. (shrink)

We argue that the causal account offered by analytic functionalism provides the best account of the folk psychological theory of mind, and that people ordinarily define mental states relative to the causal roles these states occupy in relation to environmental impingements, external behaviors, and other mental states. We present new empirical evidence, as well as review several key studies on mental state ascription to diverse types of entities such as robots, cyborgs, corporations and God, and explain how this evidence supports (...) a functional account. We also respond to two challenges to this view based on the embodiment hypothesis, or the claim that physical realizers matter over and above functional role, and qualia. In both cases we conclude that research to date best supports a functional account of ordinary mental state concepts. (shrink)

There has been much discussion about the nature and even existence of so-called “pure conscious events” (PCEs). PCEs are often described as mental events which are non-conceptual and lacking all experiential content (Forman 1990). For a variety of reasons, a number of authors have questioned both the accuracy of such a characterization and even the very existence of PCEs (Katz 1978, Bagger 1999). In this chapter, I take a somewhat different, but also critical, approach to the nature and possibility of (...) PCEs. I focus on several overlapping views found in recent analytic philosophy of mind and examine PCEs in light of them. After introducing terminology and some preliminary matters, I examine whether or not the “higher-order thought (HOT) theory of consciousness” rules out the possibility of PCEs, and conversely, whether or not PCEs show that the HOT theory cannot apply to all conscious states. The HOT theory says that what makes a mental state conscious is that it is accompanied by a higher-order thought to the effect that “I am in mental state M now.” A related theme will be to assess PCEs in light of the recent debate between so-called “conceptualists” and those who believe that there are “non-conceptual contents of experience.” Conceptualism, to which I am very sympathetic, is basically the view that all conscious experience is structured by concepts possessed by the subject. I argue that PCEs are indeed conceptual and so no threat to conceptualism. For example, standard criticisms of conceptualism do not apply to PCEs. Finally, I examine the possibility that PCEs are not conscious at all. In the end, my overall conclusion is that we should hold that PCEs are indeed compatible with both HOT theory and conceptualism or seriously question the idea that PCEs are conscious at all.

Defending or attacking either functionalism or computationalism requires clarity on what they amount to and what evidence counts for or against them.

Higher-order theories of consciousness posit that a mental state is conscious by virtue of being represented by another mental state, which is therefore a higher-order representation (HOR). Whether HORs are construed as thoughts or experiences, higher-order theorists have generally contested whether such metarepresentations have any significant cognitive function. In this paper, I argue that they do, focusing on the value of conscious thinking, as distinguished from conscious perceiving, conscious feeling, and other forms of conscious mentality. A thinking process is constituted (...) by propositional-attitude states, and during conscious thinking some or all of these states would be targeted by HORs. Since cases of nonconscious thinking are widely accepted, the question arises as to the use of representing one's thoughts during thinking. Contra the views of Armstrong and Rolls, I argue that HORs do not facilitate first-order thinking. Rather, I propose that such representations enable reasoning about one's act of thinking, and I give various examples of this sort of metacognition in support of the theory. I further argue that the general correlation between complex thinking and its being conscious is merely due to the fact that assessing one's mental act is particularly useful during such thinking, not because consciousness somehow facilitates first-order inference-making, as folk psychology implies. My view is thus consistent with recent empirical evidence that complex thinking sometimes yields better results when nonconscious. (shrink)

The paper begins by considering David Armstrong's beautiful paper 'The Headless Woman Illusion and the Defence of Materialism', which conjectures how we get the illusion that there are non-physical qualia. There are discussions of other metaphysical illusions, that there is a passage of time, that we have libertarian free will, and that consciousness is ineffable (which last also relates to Armstrong), and of their possible explanations. Moral: avoid appeal to so called intuition or phenomenology.

This paper argues that the behaviorist label yields a caricature of Ryle's position in The Concept of Mind that cannot be adequately fleshed out by reference to the larger corpus of Rylean texts. On the interpretation of Ryle that I offer here, he is best characterized as an "ontological agnostic." Ryle's aim, I believe, is to develop a nondenotational theory of meaning for mental-conduct terms--a theory of meaning which does not presuppose any metaphysical or ontological theory and, hence, does not (...) presuppose behaviorism.
