This thesis evaluates several powerful arguments that not only deny that brain states and conscious states are one and the same thing, but also claim that such an identity is unintelligible. I argue that these accounts do not undermine physicalism because they don’t provide any direct or independent justification for their tacit assumptions about a link between modes of presentation and explanation. In my view intelligibility of psychophysical identity should not be based exclusively on the analysis of meaning. The main (...) concern then should be why expect that fully intelligible explanation must be based on the descriptions of the causal roles as modes of presentation. To this effect I propose that we examine "psychological concepts". The psychological concepts are concepts that use descriptions of the functional roles but are about qualities of our experiences. I propose to analyze them in quality space models in order to unveil why phenomenal concepts are expected to refer via descriptions of the causal or functional roles. The quality space should be understood here as a multidimensional space consisting of several axes of relative similarity and differences among the structures of ordering in different modalities of conscious experience. On my proposal it is possible that some axes in the quality space consist of their own quality spaces so we could “zoom in” and “zoom out” into the descriptions of the functional roles and see more clearly what the explanation of certain aspects of consciousness looks like when thought of in terms of psychological concepts.

I assume that there exists a general phenomenon, the phenomenon of the explanatory gap, surrounding consciousness, normativity, intentionality, and more. Explanatory gaps are often thought to foreclose reductive possibilities wherever they appear. In response, reductivists who grant the existence of these gaps have offered countless local solutions. But typically such reductivist responses have had a serious shortcoming: because they appeal to essentially domain-specific features, they cannot be fully generalized, and in this sense these responses have been not just (...) local but parochial. Here I do better. Taking for granted that the explanatory gap is a genuine phenomenon, I offer a fully general diagnosis that unifies these previously fragmented reductivist responses. (shrink)

Recent philosophy has seen a resurgence of the realist view of sensible qualities such as colour. The view holds that experienced qualities are properties of the objects in the physical environment, not mentally instantiated properties like qualia or merely intentional, illusory ones. Some suggest that this move rids us of the explanatory gap between physical properties and the qualitative features of consciousness. Others say it just relocates the problem of qualities to physical objects in the environment, given that (...) such qualities cannot be derived from the non-qualitative properties of objects, and it does not resolve the problem of consciousness either. I argue that such an outcome is welcome: if the physical world is full of explanatory gaps, then the mind–body explanatory gap is not so special. Moreover, the explanatory gaps regarding qualities of objects are less puzzling than the brain-qualia gap. In order to counter the usual worries concerning realism about objective qualities, I introduce ‘imperfect realism’ as an alternative to colour pluralism and complex reductionism, which accommodates realism in the face of widespread perceptual error. I conclude with a discussion of how this ‘multiple-gaps view’ sits better with a naturalistic framework compared to the Galilean-Cartesian account of qualities. (shrink)

We develop a partial solution to the meta-problem of consciousness that builds on our previous psychological account of an apparent explanatory gap. Drawing from empirical work on explanatory cognition and conceptual development, we sketch a profile of cognitive systems for which primitive concepts facilitate explanatory gaps. This account predicts that there will be multiple explanatory gaps. We suggest that this is borne out by the existence of primitivist theories in multiple philosophical domains.

I argue that O'Regan & Noë's (O&N's) theory is in a no better position than any other theory to solve the “hard problem” of consciousness. Getting rid of the explanatory gap by exchanging sensorimotor contingencies for neural representations is an illusion.

One way to express the most persistent part of the mind-body problem is to say that there is an “explanatory gap” between the physical and the mental. The gap is not usually taken to apply to all of the mental, but to subjective experience, the mind’s “qualitative” features, or what is now referred to as “phenomenal consciousness.” The “gap” formulation is due to Joseph Levine. He acknowledged the appeal of intuitions of separability between physical facts, of any kind (...) we can envisage, and this aspect of our mental lives. Subjective experience seems not to be the sort of thing that is just the physical under another guise. The immediate focus of Levine’s discussion was a family of arguments due to Saul Kripke. Kripke argued that some influential claims of mind-body identity could not be, as materialists claimed, contingent. If these identities are real then they are necessary. But we can clearly conceive that the mental and physical could come apart—an intuition that “identity theorists” conceded. Given that the identity is necessarily present if present at all, from the fact it is not necessary we can see it is absent. Kripke concluded that physicalism is false. Levine wanted to resist this.

While substantial progress has been made in the field known as artificial consciousness, at the present time there is no generally accepted phenomenally conscious machine, nor even a clear route to how one might be produced should we decide to try. Here, we take the position that, from our computer science perspective, a major reason for this is a computational explanatory gap: our inability to understand/explain the implementation of high-level cognitive algorithms in terms of neurocomputational processing. We explain how (...) addressing the computational explanatory gap can identify computational correlates of consciousness. We suggest that bridging this gap is not only critical to further progress in the area of machine consciousness, but would also inform the search for neurobiological correlates of consciousness and would, with high probability, contribute to demystifying the “hard problem” of understanding the mind–brain relationship. We compile a listing of previously proposed computational correlates of consciousness and, based on the results of recent computational modeling, suggest that the gating mechanisms associated with top-down cognitive control of working memory should be added to this list. We conclude that developing neurocognitive architectures that contribute to bridging the computational explanatory gap provides a credible and achievable roadmap to understanding the ultimate prospects for a conscious machine, and to a better understanding of the mind–brain problem in general.

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 , 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)

In this chapter, I revisit the issue of the explanatory gap that is supposed to open when considering identity statements between physical and mental phenomena. I show that the question asked in the original formulation of the explanatory gap was this: ʻwhy this phenomenal character, rather than any other, is attached to this physiological process?ʼ I argue that this question can be answered, because there is a natural fit between the phenomenal character of experiences and their functional roles. (...) For example, pains feel inherently unpleasant, and that explains why they cause avoidance behaviour, and the felt location and intensity of pain indicates the location and extent of damage to the body. I discuss some other possible gaps in our understanding the relationship between the mental and the physical, and conclude that the fit between functional role and phenomenal character goes a long way, though probably not the whole way, to closing the explanatory gap.

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 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.

Contrary to certain rumours, the mind-body problem is alive and well. So argues Joseph Levine in Purple Haze: The Puzzle of Consciousness . The main argument is simple enough. Considerations of causal efficacy require us to accept that subjective experiential, or 'phenomenal', properties are realized in basic non-mental, probably physical properties. But no amount of knowledge of those physical properties will allow us conclusively to deduce facts about the existence and nature of phenomenal properties. This failure of deducibility constitutes (...) an explanatory problem - an explanatory gap - but does not imply the existence of immaterial mental properties. Levine introduced this notion of the explanatory gap almost two decades ago. Purple Haze allows Levine to situate the explanatory gap in a broader philosophical context. He engages with those who hold that the explanatory gap is best understood as implying anti-materialist metaphysical conclusions. But he also seeks to distance himself from contemporary naturalistic philosophical theorizing about consciousness by arguing that reductive and eliminative theories of consciousness all fail. Levine's work is best seen as an attempt to firmly establish a definite status for the mind-body problem, i.e. that the mind-body problem is a real, substantive epistemological problem but emphatically not a metaphysical one. Because Levine's work is tightly focused upon contemporary Anglophone analytic philosophy of mind, there is little discussion of the broader conceptual background to the mind-body problem. My aim here is to place Levine's work in a broader conceptual context. In particular, I focus on the relationship between consciousness and intentionality in the belief that doing so will allow us better to understand and evaluate Levine's arguments and their place in contemporary theorizing about mentality and consciousness.

There has been much recent discussion of whether Husserlian phenomenology might be relevant to the explanatory gap—the problem of explaining how conscious experience arises from nonexperiential events or processes. However, some phenomenologists have argued that the explanatory gap is a confused problem, because it starts by assuming a false distinction between the subjective and the objective. Rather than trying to solve this problem, they claim that phenomenology should dissolve it by undermining the distinction upon which (...) it is based. I shall argue that adopting a phenomenological approach does not provide reason to think that the explanatory gap is not a genuine problem. In assessing the assumptions underlying the gap, we must distinguish between objectivity understood as a stance we can take toward the world and objectivity as the world's having a structure independent of any experience. The explanatory gap can be understood as the problem of finding a place for consciousness in this objective structure. This does not force us to take an objective stance or reduce the methods of phenomenology to those of the natural sciences. (shrink)

Open peer commentary on the article “Never Mind the Gap: Neurophenomenology, Radical Enactivism, and the Hard Problem of Consciousness” by Michael D. Kirchhoff & Daniel D. Hutto. Upshot: I strongly agree with Kirchhoff and Hutto that consciousness and embodied action are one and the same, but I disagree when they say this identity cannot be fully explained and must simply be posited. Here I attempt to sketch the outlines of just such an explanation.

Discussions of the mind-body problem often refer to an.

This paper considers the so-called explanatory gap between brain activity and conscious experience. A number of different, though closely related, explanatory gaps are distinguished and a monistic account of conscious experience, a version of Herbert Feigl’s “twofold-access theory,” is advocated as a solution to the problems they are taken to pose for physicalist accounts of mind. Although twofold-access theory is a version of the mind-body identity thesis, it in no way “eliminates” conscious experience; rather, it provides a parsimonious (...) and explanatorily fruitful theory of the consciousness-body relation which faithfully preserves the nature of conscious experience while going quite far in “bridging” the various explanatory gaps distinguished below.

In Cognitive science and philosophy of consciousness, the explanatory gap, following Joseph Levine, refers to the unintelligible link between our conscious mental life and its corresponding objective physical explanation; the gap in our understanding of how consciousness is related to a physical or a physiological substrate :354–361, 1983). David Chalmers holds the explanatory gap as the evidence for a form of metaphysical dualism between consciousness and physical reality. On the other hand, McGinn takes it as an epistemic rather (...) than an ontological gap. Considering the recent advances in neuroscience, however, the reductionist approaches have become replete, which attempt to reduce consciousness and subjectivity to neurobiological accounts. On this view, consciousness mirrors the brain mechanisms, and the self is formulated as an illusory product or construct of neuronal processes. Thomas Fuchs, who is committed to embodied and enactive approaches toward cognition, in Ecology of the Brain, espouses an enactive-ecological perspective concerning the problem of the explanatory gap. He develops an account of human’s life in its dual aspects of the living body and lived body which, on the one hand, defies the ontological dualism and, on the other hand, avoids drifting towards any form of reductionism. Often, the ontologically monistic approaches to the explanatory gap have inclined to a form of reductionism because they conceive consciousness as either identical with its physiological substrate or caused by it, where in both cases, consciousness is claimed to be explainable within the framework of physicalism. Fuchs, however, defends an ontological monism which remains irreconcilable with reductionism. In his account of dual aspects, there is no interaction or impact between the sphere of subjectivity and nature; however, these two aspects imply one another. In this essay, I will develop the philosophical justification of the above reformulation of the mind–body problem and employing the analogy of light will canvass the paradoxical relationship between dual aspects in a phenomenological framework.

The explanatory gap and theknowledge argument are rooted in the conflationof propositional and phenomenal knowledge. Thebasic knowledge argument is based on theconsideration that ``physical information'' aboutthe nervous system is unable to provide theknowledge of a ``color experience'' . The implication is that physicalism isincomplete or false because it leaves somethingunexplained. The problem with Jackson'sargument is that physical information has theform of highly symbolic propositional knowledgewhereas phenomenal knowledge consists in innateneurophysiological processes. In addition totheir fundamental epistemological differences,clinical, anatomical, pathological (...) and brainimaging studies demonstrate that phenomenal andpropositional knowledge are fundamentallydifferent neurobiological processes. Propositional knowledge is phylogeneticallynew, highly symbolic, culturally acquired,exclusively human and expressible in differentnatural and artificial languages. By contrast,phenomenal knowledge consists inqualitative experiences and phenomenal conceptsthat provide an internal, language-independentreference to the properties of objects and theneeds of the organism. Language andpropositional knowledge are exclusively humanattributes implemented in specific regions ofthe dominant hemisphere. This contrastssharply with the phylogenicallysensory areas that are common to animals andhumans, which implement qualitativeexperiences. Experiences are hard-wiredneurobiological processes that can neither betransmitted nor re-created through thesymbolism of propositions. Thus, I concludethat the fallacy in the explanatory gap and inthe knowledge argument is a fallacy ofequivocation that results from ignoringfundamental neurobiological differences betweenphenomenal and propositional knowledge.

Consciousness often presents itself as a problem for materialists because no matter which physical explanation we consider, there seems to remain something about conscious experience that hasn't been fully explained. This gives rise to an apparent explanatory gap. The explanatory gulf between the physical and the conscious is reflected in the broader population, in which dualistic intuitions abound. Drawing on recent empirical evidence, this essay presents a dual-process cognitive model of consciousness attribution. This dual-process model, we suggest, (...) provides an important part of the explanation for why dualism is so attractive and the explanatory gap so vexing. (shrink)

This paper critiques the view that consciousness is likely something extra which accompanies or is produced by neural states, something beyond the functional cognitive processes realized in the brain. Such a view creates the `explanatory gap'between function and nomenology which many suppose cannot be filled by functionalist theories of mind. Given methodological considerations of simplicity, ontological parsimony, and theoretical conservatism, an alternative hypothesis is recommended, that subjective qualitative experience is identical to certain information-bearing, behaviour-controlling functions, not something which emerges (...) from them. This hypothesis explains the isomorphism between the structure of experience and neural organization, while providing a naturalistic account of qualiait's relational properties of informational states, not a sparate ontology of phenomenal essences. On this functionalist view, the hard, empirical problem of consciousness is to discover precisely which neural functions constitute subjective experience. (shrink)

The problem of understanding how physical processes in the brain could give rise to consciousness has been identified with the 'comparative explanatory gap', the problem of explaining why different experiences have the differing qualities they do, and the 'absolute explanatory gap', the problem of explaining why anything can be conscious at all. The main innovation of the sensorimotor theory is that it provides a very appealing way of closing the comparative gap by postulating that the (...) quality of experiences corresponds to objective sensorimotor laws that characterize one's bodily interaction with the environment. Here I expound in greater detail how the approach deals with the absolute gap. I refine my previous efforts at understanding what we mean by 'being conscious of something' by abandoning my previous hierarchical approach; by introducing the concept of 'mental manipulation'; and by relying more on a notion of self than I have done previously. I end up with a more variegated notion of consciousness than in previous work, that includes the idea of a complex interwoven patchwork of consciousness with no simple conscious/nonconscious distinction across different species or agents. The approach suggests we need to review the links between consciousness and ethics. (shrink)

The scope of Platonism is extended by introducing the concept of a “Platonic computer” which is incorporated in metacomputics. The theoretical framework of metacomputics postulates that a Platonic computer exists in the realm of Forms and is made by, of, with, and from metaconsciousness. Metaconsciousness is defined as the “power to conceive, to perceive, and to be self-aware” and is the formless, con-tentless infinite potentiality. Metacomputics models how metaconsciousness generates the perceived actualities including abstract entities and physical and nonphysical realities. (...) It is postulated that this is achieved via digital computation using the Platonic computer. The introduction of a Platonic computer into the realm of Forms thus bridges the “inverse explanatory gap” and therefore solves the “inverse hard problem of consciousness” in the philosophy of mind.

Wittgenstein demystified the notion of 'observational self-knowledge'. He dislodged the long-standing conception that we have privileged access to our impressions, sensations and feelings through introspection, and more precisely eliminated knowing as the kind of awareness that normally characterizes our first-person present-tense psychological statements. He was not thereby questioning our awareness of our emotions or sensations, but debunking the notion that we come to that awareness via any epistemic route. This makes the spontaneous linguistic articulation of our sensations and impressions nondescriptive. (...) Not descriptions, but expressions that seem more akin to behaviour than to language. I suggest that Wittgenstein uncovered a new species of speech acts. Far from the prearranged consecration of words into performatives, utterances are deeds through their very spontaneity. This gives language a new aura: the aura of the reflex action. I argue, against Peter Hacker, that spontaneous utterances have the categorial status of deeds. This has no reductive consequences in that I do not suggest that one category is reduced to another, but that the boundary between them is porous. This explodes the myth of an explanatory gap between the traditionally distinct categories of saying (or thinking) and doing, or of mind and body. (shrink)

The epistemological chasm between how we (implicitly and subjectively) perceive or imagine the actual world and how we (explicitly and “objectively”) think of its underlying entities has motivated perhaps the most disconcerting impasse in human thought: the explanatory gap between the phenomenal and physical properties of the world. Here, I advocate a combination of philosophical skepticism and simplicity as an informed approach to arbitrate among theories of consciousness. I argue that the explanatory gap is rightly a gap in (...) our understanding, but one that is not surprising; and we being observers biased by our first-person perspective and our existence may both hinder and (the realization we have them) assist our reasoning. Further, I unfold the concept of observer into two distinct notions based on its functional and phenomenal aspects, and exploit this device to elucidate the subject-observer relationship. Then, I proceed to analyze the philosophical zombie dilemma. Lastly, I contend that from a skeptical viewpoint, panpsychism (or neutral monism) is the most parsimonious doctrine accounting for the explanatory gap, and suggest that it would be possible to make headway in the hard problem of consciousness by uncovering non-trivial causal relationships between qualia states and functional states, if routine and controlled manipulation of neural circuits were easily available.

The contemporary epistemic status of mental health disciplines does not allow the cross validation of mental disorders among various genetic markers, biochemical pathway or mechanisms, and clinical assessments in neuroscience explanations. We attempt to provide a meta-empirical analysis of the contemporary status of the cross-disciplinary issues existing between neuro-biology and psychopathology. Our case studies take as an established medical mode an example cross validation between biological sciences and clinical cardiology in the case of myocardial infarction. This is then contrasted with (...) the incoherence between neuroscience and psychiatry in the case of bipolar disorders. We examine some methodological problems arising from the neuro-imaging studies, specifically the experimental paradigm introduced by the team of Wayne Drevets. Several theoretical objections are raised: temporal discordance, state independence, and queries about the reliability and specificity, and failure of convergent validity of the inter-disciplinary attempt. Both modern neuroscience and clinical psychology taken as separate fields have failed to reveal the explanatory mechanisms underlying mental disorders. The data acquired inside the mono-disciplinary matrices of neurobiology and psychopathology are deeply insufficient concerning their validity, reliability, and utility. Further, there haven’t been developed any effective trans-disciplinary connections between them. It raises the requirement for development of explanatory significant multi-disciplinary “meta-language” in psychiatry (Berrios, 2006, 2008). We attempt to provide a novel conceptual model for an integrative dialogue between psychiatry and neuroscience that actually includes criteria for cross-validation of the common used psychiatric categories and the different assessment methods. The major goal of our proactive program is the foundation of complementary “bridging” connections of neuroscience and psychopathology which may stabilize the cognitive meta-structure of the mental health knowledge. This entails bringing into synergy the disparate discourses of clinical psychology and neuroscience. One possible model accomplishment of this goal would be the synergistic (or at least compatible) integration of the knowledge under trans-disciplinary convergent cross-validation of the commonly used methods and notions.

J. G. Taylor advances an empirically testable local neural network model to understand the neural correlates of phenomenal experience. Taylor's model is better able to explain the presence and unity of phenomenal consciousness which support the idea that consciousness is coherent, undivided, and centered.

In addition, the ontological assumptions that PE is immediate, intrinsic, and incorrigible limit an understanding of the different experiential (...) forms consciousness takes during neurobehavioral development. Recent studies suggest that neurobehavioral development is discontinuous and that judgment emerges under conditions of uncertainty to render feeling and perception in equivalent terms of energy and behavior.

Two decades in, whether we are making any progress towards solving, or even explaining away, what David Chalmers calls the ‘hard’ problem of consciousness is as controversial as ever. This paper aims to argue that there are, in actual fact, two explanatory targets associated with the hard problem.

The paper ends with a brief exposition of (...) how the present distinction goes beyond similar ones already made by respondents to Joseph Levine's explanatory gap. (shrink)

Integrated Information Theory (IIT) of Consciousness is becoming an increasingly popular neuroscientific account of phenomenal experience. IIT claims that consciousness is integrated information in a system. I set this theory against the hard problem of consciousness (Chalmers, 1996, 1995) as the goal for a theory of consciousness to meet. In this essay I look to examine and ultimately critique IIT’s use of the notion of information to base a theory of consciousness. I argue that the notion of information in (...) IIT is a purely structural-dynamical notion, and so falls afoul of the structure and dynamics argument (Chalmers, 2003). I bolster these claims by appeal to the explanatory gap argument and show how IIT succumbs to this argument as well. For these reasons, I call into doubt IIT’s ability to answer the hard problem of consciousness. Although this paper argues against the notion of information in IIT, in a broader context the criticisms which I raise here can be brought against any theory that attempts to explain consciousness as an information-theoretic phenomenon.

A new strategy in philosophy of law appeals to explanatory gap arguments to attack legal positivism. We argue that the strategy faces a dilemma, which derives from there being two available readings of the constraint it places on legal grounding. To this end, we elaborate the most promising ways of spelling out the epistemic constraints governing law-determination, and show that each of the arguments based on them has problems. Throughout the paper, we evaluate a number of explanatory requirements, (...) ultimately with a view to shedding light on the explanatory nature of both grounding in general, and legal grounding in particular.

Important features of space and time are taken to be missing in quantum gravity, allegedly requiring an explanation of the emergence of spacetime from non-spatio-temporal theories. In this paper, we argue that the explanatory gap between general relativity and non-spatio- temporal quantum gravity theories might significantly be reduced with two moves. First, we point out that spacetime is already partially missing in the context of general relativity when understood from a dynamical perspective. Second, we argue that most approaches to (...) quantum gravity already start with an in-built distinction between structures to which the asymmetry between space and time can be traced back.

Spacetime functionalism is the view that spacetime is a functional structure implemented by a more fundamental ontology. Lam and Wüthrich have recently argued that spacetime functionalism helps to solve the epistemological problem of empirical coherence in quantum gravity and suggested that it also (dis)solves the hard problem of spacetime, namely the problem of offering a picture consistent with the emergence of spacetime from a non-spatio-temporal structure. First, I will deny that spacetime functionalism solves the hard problem (...) by showing that it comes in various species, each entailing a different attitude towards, or answer to, the hard problem. Second, I will argue that the existence of an explanatory gap, which grounds the hard problem, has not been correctly taken into account in the literature. (shrink)

On the first page of The Problem of Consciousness , Colin McGinn asks "How is it possible for conscious states to depend on brain states? How can technicolour phenomenology arise from soggy grey matter?" Many philosophers feel that questions like these pose an unanswerable challenge to physicalism.

An explanatory gap ensues when the truths constituting the explanans do not entail the explanandum. Attempts to give a physicalist account of consciousness seem to generate an explanatory gap, which is special in the following psychological sense. In other cases, it is possible to bridge or close the gap by regimenting or eliminating the respective concepts. In the case of consciousness, however, there is a pervasive intuition that the gap remains even when one works out a notion of (...) consciousness that allows the entailment of truths about consciousness from physical premises. The intuition is expressed by the sense that something essential about consciousness is left out from any such conceptual regimentation. This paper defends the view that this intuition is generated by the way our experiences are given to us. Every experience has a component that is not captured by any specification. The gap intuition is due to this ineffable component in experiences. Since conscious experiences are partly ineffable, it seems that no account of consciousness captures conscious experiences entirely and so would develop the intuition that something has been left out. An alternative explanation to the gap intuition is provided by the “phenomenal concepts’ strategy”. According to this strategy, it is the peculiar nature of phenomenal concepts that feeds the intuition. The main problem with such an approach is that phenomenal concepts are more coarse-grained than the experiences themselves and thus their application still does not entail what it is like to have a particular phenomenal experience.

For a theory of phenomenal consciousness, the real issue is not that between vehicle and process, but between naturalistic and deconstructive theories. Most current naturalistic theories combine a hypothesis about the neural correlate of consciousness with a subsequent naturalistic proposal about how to close the explanatory gap. Deconstructive theories use theses about the neural correlate of consciousness only to motivate and support their claim that the “hard problem” of consciousness is a pseudo-problem which is not to be (...) solved, but rather dissolved on non-naturalistic grounds. O'Brien & Opie present a hypothesis concerning the neural correlate of consciousness, but no genuine strategy to close the explanatory gap. Their theory can, however, contribute to the success of a deconstructive theory of PC. (shrink)

In this chapter, the author wants to respond to Noam Chomsky's claim, repeated often in different ways. He argues both that Chomsky's own position suffers from inconsistency – he dismisses the apparent problem while at the same time promoting it as a “mystery” – and that his principal reason for maintaining his position, that there is no clear conception of body, or the physical, with which to contrast the mind, or the mental, does not really dispense with the issue (...) that rightfully worries philosophers. A good analogy for the mind–body problem is the “naturalization” debate in metaethics; indeed, naturalization is a term that occurs often in the context of both debates. Chomsky explicitly disparages the claim that the mental–physical relation poses an “explanatory gap." Maybe, as Chomsky says concerning at least some mental attributes, it will always remain a mystery how the organized matter of our brains can support these features. (shrink)

This paper explores the enactive approach in cognitive science with an eye on the later Wittgenstein’s philosophy. The aim is not that of answering the question: was Wittgenstein an ante litteram enactivist? He was not, because he was not an ante litteram (cognitive) scientist of any kind. The aim, conversely, is that of answering the question: can enactivism be Wittgensteinian? In answering positively, it will be argued that a Wittgensteinian framework can help enactive cognitive scientists in dissolving certain old problems (...) which they sometimes seem not to be able to get rid of. After the Introduction, the first two sections of the paper concern the Wittgensteinian standpoint on psychological concepts (Section 2) and the enactivist approach in its general terms (Section 3). Section 4 attempts a closer examination of some key concepts – chiefly representations, the inner, the “explanatory gap”, the “hard problem” of consciousness – considering both the enactivists’ and Wittgenstein’s attitude towards them. The Conclusion surmises the benefits of a Wittgensteinian perspective also hinting at some other problems which it can help to clarify. (shrink)

I propose to solve the hard problem in the philosophy of mind by means of Brandom‟s notion of the pragmatically mediated semantic relation. The explanatory gap between a phenomenal concept and the corresponding theoretical concept is a gap in the pragmatically mediated semantic relation between them. It is closed if we do not neglect the pragmatics.

[opening paragraph]: In recent years, David J. Chalmers has forcefully made a point that I consider to be extremely important for the study of consciousness, also from a Husserlian perspective. The point is that conscious experience is ‘an explanandum in its own right’ . In order to make progress in addressing the problem of the explanatory gap between physical processes and conscious experience, new approaches are therefore to be explored. As Chalmers has it, ‘a mere account of the (...) functions stays on one side of the gap, so the materials for the bridge must be found elsewhere’ . Now, as I see it, the editors of this Special Issue pursue, precisely, the most promising avenue for adequately studying the problem of consciousness in such an exploratory spirit. For, in their excellent Introduction, they un- equivocally propose to include first-person, subjective experience as an explicit and active component of a science of consciousness, to be elaborated with appropriate methods by a research community. Jonathan Shear already put it very clearly elsewhere: ‘what is needed . . . is not so much new conceptualizations of science or new objective methodologies for exploring relationships of the phenomena of consciousness to physiology and behaviour . . . but new systematic methodologies for the exploration of the subjective phenomena of consciousness’ . Among such methodologies, the editors now include ‘the most important western school of thinking where experience and consciousness is at the very heart: Phenomenology as inaugurated by Edmund Husserl . . .’.

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, and that means all three problems remain unsolved (in that there is no other obvious candidate for a solution). Here, it is argued that the first problem cannot have a solution; this is inherent in the nature of explanation. The second (...) class='Hi'>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 most pressing worry for panpsychism is arguably the combination problem, the problem of intelligibly explaining how the experiences of microphysical entities combine to form the experiences of macrophysical entities such as ourselves. This chapter argues that the combination problem is similar in kind to other problems of mental combination that are problems for everyone: the problem of phenomenal unity, the problem of mental structure, and the problem of new quality spaces. The ubiquity of (...) combination problems suggests the ignorance hypothesis, the hypothesis that we are ignorant of certain key facts about mental combination, which allows the panpsychist to avoid certain objections based on the combination problem.

In this book, each of the possible positions concerning the relationship between mind and body is clearly explained and thoroughly critiqued. It is concluded that, although mental events are identical with physical events, mentalistic statements are not equivalent with physicalistic statements. It is also shown that the way in which mentalistic statements are non-equivalent with physicalistic statements is deeper than the way in which biological statements are non-equivalent with microphysical statements. In other words, the sense in which mind and body (...) lie on opposite sides of an 'explanatory gap' is much stronger than the sense in which biology and microphysics do so. (shrink)

Each well-known proposed solution to the mind-body problem encounters an impasse. These take the form of an explanatory gap, such as the one between mental and physical, or between micro-subjects and macro-subject. The dialectical pressure to bridge these gaps is generating positions in which consciousness is becoming increasingly foundational. The most recent of these, cosmopsychism, typically casts the entire cosmos as a perspectival subject whose mind grounds those of more limited subjects like ourselves. I review the dialectic from (...) materialism and dualism through to panpsychism, suggesting that explanatory gaps in the latter stem from assuming foundational consciousness to be perspectival. Its renunciation may yield the notion of an aperspectival, universal, “non-dual” consciousness that grounds all manifestation and is unstructured by subject, object or any differentia. Not only is such consciousness suggestive of a natural successor to cosmopsychism, but it has also been reported to be the direct experience of mystics who claim to have transcended the individual perspective. Their purported insight — that our aperspectival conscious nature is identical to the ground of all being — has been termed “the Perennial Philosophy”. Believing this Perennial Philosophy to offer the most promising way forward in the mind-body problem, I construct from it the foundations of a metaphysical system that I call “Perennial Idealism”. This attempts to account for manifestation in terms of dispositional, imagery-bound subjects. I then address an age-old “Parmenidean” conundrum that I refer to as “the problem of the one and the many”: How can an undifferentiated substratum ground differentia without the ground itself differentiating? The proposed solution takes its cue from mystico-philosophical writings in the Advaita Vedānta tradition, known as the ajāta doctrine. (shrink)

Recent attempts to show that functional processing entails the presence of phenomenal consciousness have failed to deliver the kind of answers to the “problems of consciousness” that anti-materialists insist the functionalist must provide. I will illustrate this by focusing on the claims that there is a special “Hard Problem” of consciousness and an “explanatory gap” between functional and phenomenal facts. I then argue that if we supplement the functionalist stories with a relationalist conception of phenomenal properties, we can (...) begin to see the shape of a naturalistic theory of phenomenal consciousness that will provide intuitively compelling responses to these problems.

A growing consensus in the philosophy and psychology of concepts is that while theories such as the prototype, exemplar, and theory theories successfully account for some instances of concept formation and application, none of them successfully accounts for all such instances. I argue against this ‘new consensus’ and show that the problem is, in fact, more severe: the explanatory force of each of these theories is limited even with respect to the phenomena often cited to support it, as (...) each fails to satisfy an important explanatory desideratum with respect to these phenomena. I argue that these explanatory shortcomings arise from a shared assumption on the part of these theories, namely, they take similarity judgements and application of causal knowledge to be discrete elements in a theory of concepts. I further propose that the same assumption carries over into alternative theories offered by proponents of the new consensus: pluralism, eliminativism, and hybrid theories. I put forth a sketch of an integrated model of concept formation and application, which rejects this shared assumption and satisfies the explanatory desiderata I discuss. I suggest that this model undermines the motivation for hybrid, pluralist, and eliminativist accounts of concepts. _1_ Introduction _2_ The Similarity-Based Approach and the Importance of Theory _2.1_ The similarity-based approach _2.2_ The selection desideratum _2.3_ Causal knowledge as satisfying the selection desideratum _3_ The Theory-Based Approach and the Importance of Similarity _3.1_ The theory-based approach _3.2_ The range desideratum _3.3_ Similarity as satisfying the range desideratum _4_ An Integrated Approach to Concepts _4.1_ An integrated model _4.2_ The integrated theory versus hybrid theories of concepts _5_ Conclusion.

The center of this investigation is the ‘real hard problem’ of phenomenal perception (Chalmers), i.e. of the qualitative kind of perception presenting the subject with forms, colors, smell, pleasurable or negative feelings etc.; the problem of Human consciousness, however, will explicitly not be treated. The ‘explanatory gap’ (Levine) complained by the philosophy of mind, that is to say the failure of all attempts to supply a neuronal explanation of experiences, is emergence-theoretically treated: Systems own properties and laws (...) different from their components; so the emergence concept shows promise also for the explanatory potential with respect to neuronal systems. Here the phenomenal character of perception is explained from the systemic co-action of perception and behavior, whereby also an interpretation is opened to Davidson’s anomal monism. Qualitative feelings, as is further shown, are not to be understood as needless ‘epiphenomena’, but as a necessary completion of per-ception when, as in the case of higher animals, the behavior is primarily controlled by phenomenal perception.

The center of this investigation is the hard problem of phenomenal perception. To be clear, hereby it is thought of higher animals; accordingly the problem of Human consciousness will explicitly not be treated. The so-called explanatory gap (Levine), i.e. missing a neural explanation of experiences, here is emergence-theoretically countered: It is argued that systems own properties and laws different from those of their components. Applied to the brain the phenomenal character of perception is explained as an emergence (...) effect from the systemic cooperation of perception, valuation and behavior, whereby also an interpretation is opened to Davidson’s anomal monism. As is further shown, feelings are to be understood as a necessary completion of perception when, as in the case of higher animals, the behavior is primarily controlled by phenomenal perception.

Some contemporary discussion about the explanation of consciousness substantially recapitulates a decisive debate about reference, knowledge and justification from an earlier stage of the analytic tradition. In particular, I argue that proponents of a recently popular strategy for accounting for an explanatory gap between physical and phenomenal facts – the so-called “phenomenal concept strategy” – face a problem that was originally fiercely debated by Schlick, Carnap, and Neurath. The question that is common to both the older and the (...) contemporary discussion is that of how the presence or presentation of phenomenal experiences can play a role in justifying beliefs or judgments about them. This problem is, moreover, the same as what was classically discussed as the problem of acquaintance. Interestingly, both physicalist and non-physicalist proponents of the phenomenal concept strategy today face this problem. I consider briefly some recent attempts to solve it and conclude that, although it is prima facie very plausible that acquaintance exists, we have, as yet, no good account of it. (shrink)
