In this chapter I look closely at the intentionality of consciousness from a naturalistic perspective. I begin with a consideration of Gurwitsch's suggestive ideas about the role of acts of consciousness in constituting both the objects and the subjects of consciousness. I turn next to a discussion of how these ideas relate to my own empirical approach to intentional relations seen from a developmental perspective. This is followed by a discussion of some recent ideas in philosophical cognitive science on the (...) intentionality of consciousness, both with respect to the objects and the subjects of consciousness. I show that these recent trends tend to naturalize intentionality and consciousness in directions compatible with the descriptive aspects of Gurwitsch's constitutive phenomenology. (shrink)

The phenomenal properties of conscious mental states happen to be exclusively accessible from the first-person perspective. Consequently, some philosophers consider their existence to be incompatible with materialist metaphysics. In this paper I criticise one particular argument that is based on the idea that for something to be real it must (at least in principle) be accessible from an intersubjective perspective. I argue that the exclusively subjective access to phenomenal contents can be explained by the very particular nature of the epistemological (...) relation holding between a subject and his own mental states. Accordingly, this subjectivity does not compel us to deny the possibility that phenomenal contents are ontologically objective properties. First, I present the general form of the argument that I will discuss. Second, I show that this argument makes use of a criterion of reality that is not applicable to the case of subjective experience. Third, I discuss a plausible objection and give an argument for rejecting observation models of self-knowledge of phenomenal contents. These models fall prey to the homunculus illusion. (shrink)

While the study of implicit learning is nothing new, the field as a whole has come to embody — over the last decade or so — ongoing questioning about three of the most fundamental debates in the cognitive sciences: The nature of consciousness, the nature of mental representation (in particular the difficult issue of abstraction), and the role of experience in shaping the cognitive system. Our main goal in this chapter is to offer a framework that attempts to integrate current (...) thinking about these three issues in a way that specifically links consciousness with adaptation and learning. Our assumptions about this relationship are rooted in further assumptions about the nature of processing and of representation in cognitive systems. When considered together, we believe that these assumptions offer a new perspective on the relationships between conscious and unconscious processing and on the function of consciousness in cognitive systems.

Course Description: This course is designed as an upper-level seminar, with heavy emphasis on reading and writing. The reading materials are all from contemporary sources. We will cover topics such as the definitions of 'consciousness,' the neurophysiological basis of consciousness, the explanation of consciousness, and the possibility of forming a unified theory of consciousness. Student participation in class discussion is greatly encouraged.

This document consists primarily of excerpts (chapters 5 and 10-12) from the author’s book From Brain to Cosmos. These excerpts address several traditional problems about the histories of conscious subjects, using the concept of subjective fact that the author developed earlier in the book. Topics include the persistence of conscious subjects through time, the unity or disunity of the self, and the possibility of splitting conscious subjects. (These excerpts depend heavily upon the author’s concept of subjective fact as developed in (...) From Brain to Cosmos. Readers unfamiliar with that concept are strongly advised to read chapters 2 and 3 of that book first. See the last page of this document for details on how to obtain those chapters.). (shrink)

I respond to Ned Block’s claim that it is ridiculous to suppose that consciousness is a cultural construction based on language and learned in childhood. Block is wrong to dismiss social constructivist theories of consciousness on account of it being ludicrous that conscious experience is anything but a biological feature of our animal heritage, characterized by sensory experience, evolved over millions of years. By defending social constructivism in terms of both Julian Jaynes’ behaviorism and J.J. Gibson’s ecological psychology, I draw (...) a distinction between the experience or what-it-is-like of nonhuman animals engaging with the environment and the secret theater of speechless monologue that is familiar to a linguistically competent human adult. This distinction grounds the argument that consciousness proper should be seen as learned rather than innate and shared with nonhuman animals. Upon establishing this claim, I defend the Jaynesian definition of consciousness as a social–linguistic construct learned in childhood, structured in terms of lexical metaphors and narrative practice. Finally, I employ the Jaynesian distinction between cognition and consciousness to bridge the explanatory gap and deflate the supposed hard problem of consciousness. (shrink)

In "What is it Like to be a Bat?" Thomas Nagel argues that we cannot imagine what it is like to be a bat or presently understand how physicalism might be true. Both arguments have been seriously misunderstood. I defend them against various objections, point out a problem with the argument against physicalism, and show how the problem can be solved.

My purpose in this paper is to discuss and defend an objection to physicalist or materialist accounts of the mind.

This paper suggests that it is largely a want of notional distinctions which fosters the "explanatory gap" that has beset the study of consciousness since T. Nagel's revival of the topic. Modifying Ned Block's controversial claim that we should countenance a "phenomenal module" which exists in its own right, we argue that there is a way to recuperate the intuitions he appeals to without engaging in an onerous reification of the facet in question. By renewing with the full type/token/tone trichotomy (...) developed by C. S. Peirce, we think the distinctness Block (rightly) calls attention to can be seen as stemming not from any separate module lurking within the mind, but rather from our ability to prescind qualities from occurrences.

In this article I distinguish the notion of there being something it is like to be a certain kind of creature from that of there being something it is like to have a certain kind of experience. Work on consciousness has typically dealt with the latter while employing the language of the former. I propose several ways of analyzing what it is like to be a certain kind of creature and find problems with them all. The upshot is that even (...) if there is something it is like to have certain kinds of experience, it does not follow that there is anything it is like to be a certain kind of creature. Skepticism about the existence of something that it is like to be an F is recommended. (shrink)

The concept of consciousness has been the source of much philosophical, cognitive scientific and neuroscientific discussion for the past two decades. Many scientists, as well as philosophers, argue that at the moment we are almost completely in the dark about the nature of consciousness. Stuart Sutherland, in a much quoted remark, wrote that.

I discuss the meaning of 'There's something e is like', in the context of a reply to Eric Lormand's 'The explanatory stopgap'. I argue that Lormand is wrong to think it has a specially perceptual meaning. Rather, it has one of at least four candidate meanings: (a) e is some way as regards its subject; (b) e is some way and e's being that way is in the possession of its subject; (c) e is some way in the awareness of (...) its subject; (d) e's subject is the "experiencer" of e. I provide additional argumentation for the view in this paper that in the context, 'like this' functions as a predicate variable. (shrink)

The central claim of this paper is that what it is like to see green or any other perceptible property is just the perceptual mode of presentation of that property. Perceptual modes of presentation are important because they help resolve a tension in current work on consciousness. Philosophers are pulled by three mutually inconsistent theses: representational externalism, representationalism, and phenomenal internalism. I throw my hat in with defenders of the first two: the externalist representationalists. We are faced with the problem (...) of explaining away intuitions that favor phenomenal internalism. Perceptual modes of presentation account for what it is like to see properties in a way that accommodates those intuitions without vindicating phenomenal internalism itself. Perceptual MoPs therefore provide a new way of being an externalist representationalist. (shrink)

Is there an explanatory gap between raw feels and raw material? Some philosophers argue, and many other people believe, that scientific explanations of conscious experience cannot be as satisfying as typical scientific explanations elsewhere, even in our wildest dreams. The underlying philosophical claims are.

Phenomenology is based on a doctrine of evidence which accords a crucial role to human capacity to discriminate or ‘intuit’ features of their experience. However, some experiential entities to which phenomenologists are committed must be intuition-transcendent. Examples of intuition-transcendent phenomenology include the very fine grained perceptual discriminations which Thomas Metzinger calls ‘Raffman Qualia’ (Metzinger 2004, p. 74) and, crucially, the structure of temporal awareness (Roden 2006). It can be argued, on this basis, that phenomenology is in much the same epistemological (...) relationship to its own subject matter as descriptive (i.e. ‘phenomenological’) physics or biology are to physical and biological reality: phenomenology cannot tell us what phenomenology is really ‘about’. This does not entail that we should abjure phenomenological enquiry in favour of the methods of the cognitive sciences, say. It implies, rather, that the domain of phenomenology is not the province of a self-standing, autonomous discipline but must be investigated with any empirically fruitful techniques that are open to us (e.g. computational neuroscience, artificial intelligence, etc.). Finally, it entails that while a naturalized phenomenology should be retained as a descriptive, empirical method, it should not be accorded transcendental authority. If phenomenology (the discipline) cannot tell us what phenomenology (the subject of that discipline) is then it cannot limn the scope of possible phenomenologies. (shrink)

This essay is a sustained attempt to bring new light to some of the perennial problems in philosophy of mind surrounding phenomenal consciousness and introspection through developing an account of sensory and phenomenal concepts. Building on the information-theoretic framework of Dretske (1981), we present an informational psychosemantics as it applies to what we call sensory concepts, concepts that apply, roughly, to so-called secondary qualities of objects. We show that these concepts have a special informational character and semantic struc-ture that closely (...) tie them to the brain states realizing conscious qualitative experiences. We then develop an account of introspection which exploits this special nature of sensory concepts. The result is a new class of concepts, which, following recent terminology, we call phenomenal con-cepts: these concepts refer to phenomenal experience itself and are the vehicles used in introspec-tion. On our account, the connection between sensory and phenomenal concepts is very tight: it consists in different semantic uses of the same cognitive structures underlying the sensory con-cepts, such as the concept of red. Contrary to widespread opinion, we show that information the-ory contains all the resources to satisfy internalist intuitions about phenomenal consciousness, while not offending externalist ones. A consequence of this account is that it explains and pre-dicts the so-called conceivability arguments against physicalism on the basis of the special nature of sensory and phenomenal concepts. Thus we not only show why physicalism is not threatened by such arguments, but also demonstrate its strength in virtue of its ability to predict and explain away such arguments in a principled way. However, we take the main contribution of this work to be what it provides in addition to a response to those conceivability arguments, namely, a sub-stantive account of the interface between sensory and conceptual systems and the mechanisms of introspection as based on the special nature of the information flow between them.

The first-person perspective is a challenge to naturalism. Naturalistic theories are relentlessly third-personal. The first-person perspective is, well, first-personal; it is the perspective from which one thinks of oneself as oneself* without the aid of any third-person name, description, demonstrative or other referential device. The exercise of the capacity to think of oneself in this first-personal way is the necessary condition of all our self-knowledge, indeed of all our self-consciousness. As important as the first-person perspective is, many philosophers have not (...) appreciated the force of the data from the first-person perspective, and suppose that the first-person perspective presents no particular problems for the naturalizing philosopher. For example, Ned Block commented, “It is of course [phenomenal] consciousness rather than...self-consciousness that has seemed such a scientific mystery.” (Block 1995, 230) And <span class='Hi'>David</span> Chalmers says that self-consciousness is one of those psychological states that “pose no deep metaphysical enigmas.” (Chalmers 1996, 24).

Self-consciousness, many philosophers agree, is essential to being a person. There is not so much agreement, however, about how to understand what self-consciousness is. Philosophers in the field of cognitive science tend to write off self-consciousness as unproblematic. According to such philosophers, the real difficulty for the cognitive scientist is phenomenal consciousness--the fact that we (and other organisms) have states that feel a certain way. If we had a grip on phenomenal consciousness, they think, self-consciousness could be easily handled by (...) functionalist models. For example, recently Ned Block commented,. (shrink)

A number of writers have deployed the notion of a point of view as a key to the allegedly theory-resistant subjective aspect of experience. I examine that notion more closely than is usually done and find that it cannot support the anti-objectivist's case. Experience may indeed have an irreducibly subjective aspect, but the notion of a point of view cannot be used to show that it does.

George Herbert Mead's early lectures at the University of Chicago are more important to understanding the genesis of his views in social psychology than some commentators, such as Hans Joas, have emphasized. Mead's lecture series "The Evolution of the Psychical Element," preserved through the notes of student H. Heath Bawden, demonstrate his devotion to Hegelianism as a method of thinking and how this influenced his non-reductionistic approach to functional psychology. In addition, Mead's breadth of historical knowledge as well as his (...) commitments in the natural and social sciences are on display here, culminating in the Darwinian observation that human animals only achieve the degree of control they have over their environment by the achievement of social organization.

In Word and Object, Quine acknowledged the "practical indispensability" in daily life of the intentional idioms of belief and desire but disparaged such talk as an "essentially dramatic idiom" rather than something from which real science could be made in any straightforward way.Endnote 1 Many who agree on little else have agreed with Quine about this, and have gone on to suggest one or another indirect way for science to accommodate folk psychology: Sellars, Davidson, Putnam, Rorty, Stich, the Churchlands, Schiffer (...) and myself, to name a few. This fainthearted consensus is all wrong, according to Fodor, whose new book is a vigorous--even frantic--defense of what he calls Intentional Realism: beliefs and desires are real, causally involved, determinately contentful states. "We have no reason to doubt," Fodor says, "that it is possible to have a scientific psychology that vindicates commonsense belief/desire explanation." (p.16). (shrink)

What is consciousness? Of course, each of us knows, privately, what consciousness is. And we each think, for basically irresistible reasons, that all other conscious humans by and large have experiences like ours. So we conclude that we all know what consciousness is. It's the felt experiences of our lives. But that is not the answer we, as cognitive scientists, seek in asking our question. We all want to know what physical process consciousness is and why it produces this very (...) strange, almost mysterious, phenomenon of felt experience. (shrink)

Thomas Nagel contends that facts regarding the qualitative character of conscious experience can be grasped from only a single point of view. This feature, he claims, is what renders conscious experience subjective in character, and it is what makes facts about the qualitative experience subjective facts. While much has been written regarding the ontological implications of the ‘point of view account’ relatively Iittle has been said on whether the account itself successfully defines the subjectivity of the mental. In this paper, (...) I show that considerations of what can be grasped from only a single point of view provide neither necessary nor sufficient conditions for subjective experience. (shrink)

This paper is about what is distinctive about first-person beliefs. I discuss several sets of puzzling cases of first-person belief. The first focus on the relation between belief and action, while the second focus on the relation of belief to subjectivity. I argue that in the absence of an explanation of the dispositional difference, individuating such beliefs more finely than truth conditions merely marks the difference. I argue that the puzzles reveal a difference in the ways that I am disposed (...) to revise my beliefs about myself. This point develops the insight that Anscombe and others had that those of an agent's beliefs about himself that manifest that special self-consciousness are not based on observation, testimony or inference. The puzzles show that this kind of self-consciousness involves, not a special kind of belief or even a special kind of self-reference, but a special kind of belief revision policy. (shrink)

The so-called subjectivity of conscious experience is central to much recent work in the philosophy of mind. Subjectivity is the alleged property of consciousness whereby one can know what it is like to have certain conscious states only if one has undergone such states oneself. I review neurophilosophical work on consciousness and concepts pertinent to this claim and argue that subjectivity eliminativism is at least as well supported, if not more supported, than subjectivity reductionism.

Philosophical tradition contains two major lines of thought concerning the relative difficulty of the notions of objectivity and subjectivity. One tradition, which we might characterize as.

Many have urged that the biggest obstacles to a physicalistic understanding of consciousness are the problems raised in connection with the subjectivity of consciousness. These problems are most acutely expressed in consideration of the knowledge argument against physicalism. I develop a novel account of the subjectivity of consciousness by explicating the ways in which mental representations may be perspectival. Crucial features of my account involve analogies between the representations involved in sensory experience and the ways in which pictorial representations exhibit (...) perspectives or points of view. I argue that the resultant account of subjectivity provides a basis for the strongest response physicalists can give to the knowledge argument. (shrink)

Many philosophical issues concern questions of objectivity and subjectivity. Of these questions, there are two kinds. The first considers whether something is objective or subjective; the second what it _means_ for something to be objective or subjective.

Three big philosophical problems about consciousness are: Why does it exist? How do we explain and understand it? How can we explain brain-consciousness correlations? If functionalism were true, all three problems would be solved. But it is false, which means all three problems remain unsolved. Here, it is argued that the first problem cannot have a solution; this is inherent in the nature of explanation. The second problem is solved by recognizing that (a) there is an explanation as to why (...) science cannot explain consciousness, and (b) consciousness can be explained by a different kind of explanation, empathic or "personalistic" explanation, compatible with, but not reducible to, scientific explanation. The third problem is solved by exploiting David Chalmers' "principle of structural coherence", and involves postulating that sensations experienced by us visual, auditory, tactile, and so on amount to minute scattered regions in a vast, multi dimensional "space" of all possible sensations, which vary smoothly, and in a linear way, throughout the space. There is also the space of all possible sentient brain processes. There is just one, unique one-one mapping between these two spaces that preserves continuity and linearity. It is this which provides the explanation as to why brain processes and sensations are correlated as they are. I consider objections to this unique-matching theory, and consider how the theory might be empirically confirmed. (shrink)

...the problem of...how cognition...is possible at all...can never be answered on the basis of a prior knowledge of the transcendent [i.e. the external, spatio-temporal, empirical]...no matter whence the knowledge or the judgments are borrowed, not even if they are taken from the exact sciences.... It will not do to draw conclusions from existences of which one knows but which one cannot "see". "Seeing" does not lend itself to demonstration or deduction. [Husserl 1964a, pp. 2-3].

Before one can even begin to model consciousness and what exactly it means that it is a subjective phenomenon one needs a theory about what a first-person perspective really is. This theory has to be conceptually convincing, empirically plausible and, most of all, open to new developments. The chosen conceptual framework must be able to accommodate scientific progress. Its ba- sic assumptions have to be plastic as it were, so that new details and empirical data can continuously be fed into (...) the theoretical model as it grows and becomes more refined. This paper makes an attempt at sketching the outlines of such a theory, offering a representationalist analysis of the phenomenal first-person perspective. Three phenomenal target properties are centrally relevant:. (shrink)

I show that the recursive structure of Leibniz's Law requires agents to perform infinitely many operations to psychologically identify the referents of phenomenal and physical concepts, even though the referents of ordinary concepts (e.g. Hesperus and Phosphorus) can be identified in a finite number of steps. The resulting problem resembles the hard problem of consciousness in the fact that it appears (and indeed is) unsolvable by anyone for whom it arises, and in the fact that it invites dualist and eliminativist (...) responses. Moreover, if this is the hard problem then we can predict that regardless of the strength of the argument for physicalism, and regardless of physicalism's truth, an ineliminable dissatisfaction is bound to accompany any physicalist theory of consciousness. Accordingly, I suggest that this is the hard problem of consciousness, and therefore that the hard problem arises from a recursively degenerate application of Leibniz's Law. (shrink)

Human beings have the unique ability to view the world in a detached way: We can think about the world in terms that transcend our own experience or interest, and consider the world from a vantage point that is, in Nagel's words, "nowhere in particular". At the same time, each of us is a particular person in a particular place, each with his own "personal" view of the world, a view that we can recognize as just one aspect of the (...) whole. How do we reconcile these two standpoints--intellectually, morally, and practically? To what extent are they irreconcilable and to what extent can they be integrated? Thomas Nagel's ambitious and lively book tackles this fundamental issue, arguing that our divided nature is the root of a whole range of philosophical problems, touching, as it does, every aspect of human life. He deals with its manifestations in such fields of philosophy as: the mind-body problem, personal identity, knowledge and skepticism, thought and reality, free will, ethics, the relation between moral and other values, the meaning of life, and death. Excessive objectification has been a malady of recent analytic philosophy, claims Nagel, it has led to implausible forms of reductionism in the philosophy of mind and elsewhere. The solution is not to inhibit the objectifying impulse, but to insist that it learn to live alongside the internal perspectives that cannot be either discarded or objectified. Reconciliation between the two standpoints, in the end, is not always possible. (shrink)

When so much is being written on conscious experience, it is past time to face the question whether experience happens that is not conscious of itself. The recognition that we and most other living things experience non-consciously has recently been firmly supported by experimental science, clinical studies, and theoretic investigations; the related if not identical philosophic notion of experience without a subject has a rich pedigree. Leaving aside the question of how experience could become conscious of itself, I aim here (...) to demonstrate that the terms experience and consciousness are not interchangeable. Experience is a notoriously difficult concept to pin down, but I see non-conscious experience as based mainly in momentary sensations, relational between bodies or systems, and probably common throughout the natural world. If this continuum of experience — from non-conscious, to conscious, to self-transcending awareness — can be understood and accepted, radical constructivism (the “outside” world as a construct of experience) will gain a firmer foundation, panexperientialism (a living universe) may gain credibility, and psi will find its medium. (shrink)

Judgement, perception, and other mental states and events have a minimal objectivity in this sense: making the judgement or being in the mental state does not in general thereby make the judgement correct or make the perception veridical. I offer an explanation of this minimal objectivity by developing a form of constitutive transcendental argument. The argument appeals to the proper individuation of the content of judgements and perceptions. In the case of the conceptual content of judgements, concepts are individuated by (...) their fundamental reference rules. Properly developed, this resource can be used against various forms of idealism, and to defend a conception of transcendental arguments that presupposes neither verificationism nor transcendental idealism. The article contrasts its approach with other recent transcendental treatments. It also addresses the relation between its argument and Principles of Significance. I close with a discussion of the right way of handling the extreme generality necessarily involved in transcendental reasoning. (shrink)

A hypothetical evolutionary scenario is offered meant to account for the emergence of mental selves. According to the scenario, mental selves are constructed to solve a source-attribution problem. They emerge when internally generated mental contents (e.g., thoughts and goals) are treated like messages arising from external personal sources. As a result, mental contents becomes attributed to the self as an internal personal source. According to this view, subjectivity is construed outward-in, that is, one's own mental self is derived from, and (...) is secondary to, the mental selves perceived in others. The social construction of subjectivity and selfhood relies on, and is maintained in, various discourses on subjectivity. (shrink)

Thomas Nagel argues that the subjective character of mind inevitably eludes philosophical efforts to incorporate the mental into a single, complete, physically objective view of the world. Nagel sees contemporary philosophy as caught on the horns of a dilemma.

Physics says that it cannot deal with the mind-brain problem, because it does not deal in subjectivities, and mind is subjective. However, biologists (among others) still claim to seek a material basis for subjective mental processes, which would thereby render them objective. Something is clearly wrong here. I claim that what is wrong is the adoption of too narrow a view of what constitutes objectivity, especially in identifying it with what a machine can do. I approach the problem in the (...) light of two cognate circumstances: (a) the measurement problem in quantum physics, and (b) the objectivity of standard mathematics, even though most of it is beyond the reach of machines. I argue that the only resolution to such problems is in the recognition that closed loops of causation are objective; i.e. legitimate objects of scientific scrutiny. These are explicitly forbidden in any machine or mechanism. A material system which contains such loops is called complex. Such complex systems thus must possess nonsimulable models; i.e. models which contain impredicativities or self-references which cannot be removed, or faithfully mapped into a single coherent syntactic time-frame. I consider a few of the consequences of the above, in the context of thus redrawing the boundary between subject and object. (shrink)

The central thesis of this paper is that contemporary theoretical physics is grounded in philosophical presuppositions that make it difficult to effectively address the problems of subject-object interaction and discontinuity inherent to quantum gravity. The core objectivist assumption implicit in relativity theory and quantum mechanics is uncovered and we see that, in string theory, this assumption leads into contradiction. To address this challenge, a new philosophical foundation is proposed based on the phenomenology of Maurice Merleau-Ponty and Martin Heidegger. Then, through (...) the application of qualitative topology and hypernumbers, phenomenological ideas about space, time, and dimension are brought into focus so as to provide specific solutions to the problems of force-field generation and unification. The phenomenological string theory that results speaks to the inconclusiveness of conventional string theory and resolves its core contradiction. (shrink)

This essay is written at the crossroads of intuitive holism, as typified in Eastern thought, and the discursive reflectiveness more characteristic of the West. The point of departure is the age-old human need to overcome fragmentation and realize wholeness. Three basic tasks are set forth: to provide some new insight into the underlying obstacle to wholeness, to show what would be necessary for surmounting this blockage, and to take a concrete step in that direction. At the outset, the question of (...) paradox is addressed, examined in relation to Zen meditation, the problem of language, and the thinking of Heidegger. Wholeness is to be realized through paradox, and it is shown that a complete realization requires that paradox be embodied. Drawing from the fields of visual geometry and qualitative mathematics, three concrete models of paradox are offered: the Necker cube, the Moebius surface, and the Klein bottle. In attempting to model wholeness, an important limitation is recognized: a model is a symbolic representation that maintains the division between the reality represented and the act of symbolizing that reality. It is demonstrated that while the first two models are subject to this limitation, the Klein bottle, possessing higher dimensionality, can express wholeness more completely, provided that it is approached in a radically nonclassical way. The final question of this essay concerns its own capability as an essay. It is asked whether the present text is restricted to affording a mere abstract reflection on wholeness, or whether wholeness can tangibly be delivered. (shrink)

The disciplined investigation of consciousness is of three main types: eidetic, anthropological (and historical), and psychophysical. The first concerns the essence of consciousness in general and of its main modes. Its method involves introspection, empathy, and insight into necessities present in what these reveal. As the study of the essence of that which is the locus of all value it is of unique importance, and it is also essential as a foundation of the other inquiries. Such inquiry has been the (...) main task set for itself by phenomenology as a philosophical school, but engagement in it need not imply acceptance of distinctive doctrines of this school. English language?philosophy has developed in ways which discourage the eidetic investigation of consciousness, especially through insistence that modes of consciousness, conceived as a private possession, cannot be the referent of socially shared meanings. Its great mistake has been to expect ?consciousness? to refer to some elusive phenomenon to be looked for in the world and able to be studied as a distinctive reality only if conceptually isolable from what it reveals. Study of consciousness, however, is not primarily study of a phenomenon to be found within the world, but of the variety of ways in which the world can be present to us. (shrink)

This essay is a sustained attempt to bring new light to some of the perennial problems in philosophy of mind surrounding phenomenal consciousness and introspection through developing an account of sensory and phenomenal concepts. Building on the information-theoretic framework of Dretske (1981), we present an informational psychosemantics as it applies to what we call sensory concepts, concepts that apply, roughly, to so-called secondary qualities of objects. We show that these concepts have a special informational character and semantic struc-ture that closely (...) tie them to the brain states realizing conscious qualitative experiences. We then develop an account of introspection which exploits this special nature of sensory concepts. The result is a new class of concepts, which, following recent terminology, we call phenomenal con-cepts: these concepts refer to phenomenal experience itself and are the vehicles used in introspec-tion. On our account, the connection between sensory and phenomenal concepts is very tight: it consists in different semantic uses of the same cognitive structures underlying the sensory con-cepts, such as the concept of red. Contrary to widespread opinion, we show that information the-ory contains all the resources to satisfy internalist intuitions about phenomenal consciousness, while not offending externalist ones. A consequence of this account is that it explains and pre-dicts the so-called conceivability arguments against physicalism on the basis of the special nature of sensory and phenomenal concepts. Thus we not only show why physicalism is not threatened by such arguments, but also demonstrate its strength in virtue of its ability to predict and explain away such arguments in a principled way. However, we take the main contribution of this work to be what it provides in addition to a response to those conceivability arguments, namely, a sub-stantive account of the interface between sensory and conceptual systems and the mechanisms of introspection as based on the special nature of the information flow between them.

During the last two decades, several different anti-physicalist arguments based on an epistemic or conceptual gap between the phenomenal and the physical have been proposed. The most promising physicalist line of defense in the face of these arguments – the Phenomenal Concept Strategy – is based on the idea that these epistemic and conceptual gaps can be explained by appeal to the nature of phenomenal concepts rather than the nature of non-physical phenomenal properties. Phenomenal concepts, on this proposal, involve unique (...) cognitive mechanisms, but none that could not be fully physically implemented. David Chalmers has recently presented a Master Argument to show that the Phenomenal Concept Strategy – not just this or that version of it, but any version of it – fails. Chalmers argues that the phenomenal concepts posited by such theories are either not physicalistically explicable, or they cannot explain our epistemic situation with regard to qualia. I argue that it is his Master Argument that fails. My claim is his argument does not provide any new reasons to reject the Phenomenal Concept Strategy. I also argue that, although the Phenomenal Concept Strategy is successful in showing that the physicalist is not rationally compelled to give up physicalism in the light of the anti-physicalist arguments, the anti-physicalist is not rationally compelled to give up the anti-physicalist argument in the light of the Phenomenal Concept Strategy either.

At the start of the 20th century the question of whether life could be explained in purely me- chanical terms was as hotly debated as the mind-body problem is today. Two factions opposed each other: Biological mechanists claimed that the properties characteristic of living organisms (metabolism, perception, goal-directed behavior, procreation, morphogenesis) could be ex- plained mechanistically, in the way the behavior of a clock can be explained by the properties and the arrangement of its cogs, springs, and weights. Substantial vitalists, (...) on the other hand, maintained that the explanation envisaged by the mechanists was impossible and that one had to postulate a special nonphysical substance in order to explain life.

Proponents of the explanatory gap claim that consciousness is a mystery. No one has ever given an account of how a physical thing could be identical to a phenomenal one. We fully understand the identity between water and H2O but the identity between pain and the firing of C-fibers is inconceivable. Mark Johnston [Journal of philosophy (1997), 564–583] suggests that if water is constituted by H2O, not identical to it, then the explanatory gap becomes a pseudo-problem. This is because all (...) “manifest kinds”—those identified in experience—are on a par in not being identical to their physical bases, so that the special problem of the inconceivability of ‘pain = the firing of C-fibers’ vanishes. Moreover, the substitute relation, constitution, raises no explanatory difficulties: pain can be constituted by its physical base, as can water. The thesis of this paper is that the EG does not disappear when we substitute constitution for identity. I examine four arguments for the EG, and show that none of them is undermined by the move from constitution to identity. (shrink)

The explanatory gap . Consciousness is a mystery. No one has ever given an account, even a highly speculative, hypothetical, and incomplete account of how a physical thing could have phenomenal states. (Nagel, 1974, Levine, 1983) Suppose that consciousness is identical to a property of the brain, say activity in the pyramidal cells of layer 5 of the cortex involving reverberatory circuits from cortical layer 6 to the thalamus and back to layers 4 and 6,as Crick and Koch have suggested (...) for visual consciousness. (See Crick (1994).) Still, that identity itself calls out for explanation! Proponents of an explanatory gap disagree about whether the gap is permanent. Some (e.g. Nagel, 1974) say that we are like the scientifically naive person who is told that matter = energy, but does not have the concepts required to make sense of the idea. If we can acquire these concepts, the gap is closable. Others say the gap is uncloseable because of our cognitive limitations. (McGinn, 1991) Still others say that the gap is a consequence of the fundamental nature of consciousness. (shrink)
