According to representionalists, qualia-the introspectible properties of sensory experience-are exhausted by the representational contents of experience. Representationalists typically advocate an informational psychosemantics whereby a brain state represents one of its causal antecedents in evolutionarily determined optimal circumstances. I argue that such a psychosemantics may not apply to certain aspects of our experience, namely, our experience of space in vision, hearing, and touch. I offer that these cases can be handled by supplementing informational psychosemantics with a procedural psychosemantics whereby (...) a representation is about its effects instead of its causes. I discuss conceptual and empirical points that favor a procedural representationalism for our experience of space. (shrink)

We define qualia space Q to be the space of all possible conscious experience. For simplicity we restrict ourselves to perceptual experience only, though other kinds of experience could also be considered. Qualia space is a highly idealized concept that unifies the perceptual experience of all possible brains. We argue that Q is a closed pointed cone in an infinite-dimensional separable real topological vector space. This quite technical structure can be explained for the most (...) part in a simple, intuitive way. The structure of qualia space allows us to consider and even answer in a precise way such questions as: Is there a continuous path from the sensation of blue to the sensation of pain? Once we fix a desired accuracy of approximation, do there exist finitely many perceptual experiences such that any possible perceptual experience is approximately equal to one of them? What should be meant by ‘fundamentally different’ perceptual experiences? There is the possibility of additional structure, such as a Hilbert space structure on the vector space in which Q is embedded. (shrink)

How, if at all, does the internal structure of human phenomenological color space map onto the internal structure of objective reflectance‐profile space, in such a fashion as to provide a useful and accurate representation of that objective feature space? A prominent argument (due to Hardin, among others) proposes to eliminate colors as real, objective properties of objects, on grounds that nothing in the external world (and especially not surface‐reflectance‐profiles) answers to the well‐known and quite determinate internal structure (...) of human phenomenological color space. The present paper proposes a novel way to construe the objective space of possible reflectance profiles so that (1) its internal structure becomes evident, and (2) that structure’s homomorphism with the internal structure of human phenomenological color space becomes obvious. The path is thus reopened to salvage the objective reality of colors, in the same way that we preserved the objective reality of such features as temperature, pitch, and sourness—by identifying them with some objective feature recognized in modern physical theory.

Nearly all listeners consider the subjective aspects of music, such as its emotional tone, to have primary importance. But contemporary philosophers often downplay, ignore, or even deny such aspects of experience. Moreover, traditional philosophies of music try to decontextualize it. Using music as an example, this paper explores the structure of qualitative experience, demonstrating that it is multi-layer emergent, non-compositional, enacted, and situation dependent, among other non-Cartesian properties. Our explanations draw on recent work in cognitive science, including blending, image schemas, (...) and sensory memory, as well as on phenomenology. A hierarchical structure transformation based complexity theory is applied to obtain a non-linear dynamical systems explanation of qualia and emotion that respects phenomenological insights about time, including retention and protention. The complexity measure provides both a metric structure and a potential function, on spaces of pieces that are constructed using given elements and transformations, with weights that reflect their cognitive difficulty. However, the approach is not reductionist; using improvisation and the evolution of musical notation as data, we argue that situatedness, especially enactment and social context, are key aspects of musical consciousness.

The article is an approach to the possibilities of the evolution of consciousness. The research will be presented from the point of view of the Art and Mystic experiences and also compared with the biological point of view.The differences between the perception space and the representation space will be described, since it is considered that the later represents the location where the conscience processes take place. An example in the contemporary architecture on the representation space (the Jean (...) Nouvel's Agbar Tower) will be analysed. The contemporary artistic practices on living tissue manipulation will also be reviewed: artists inspired by the evolutionary laws are working nowadays with the manipulation of living tissues as artistic objects. This could be a controversial phenomenon that may drive the art-science to a materialistic position. It is for this reason that the work with consciousness could prove that the immaterial or energy is a real element that humans can manipulate as they do with living tissues. To know how to do it would be the research in art for this century and could change the direction in art-science, could change the direction of the global consciousness through a planetary culture.

What is consciousness? Some philosophers have contended that ‘qualia’, or an experiential medium from which consciousness is derived, exists as a fundamental component of reality. Whitehead, for example, described the universe as being comprised of ‘occasions of experience’. To examine this possibility scientifically, the very nature of physical reality must be re-examined. We must come to terms with the physics of space-time -- as is described by Einstein's general theory of relativity -- and its relation to the fundamental (...) theory of matter -- as described by quantum theory. This leads us to employ a new physics of objective reduction: OR which appeals to a form of ‘quantum gravity’ to provide a useful description of fundamental processes at the quantum/classical borderline . Within the OR scheme, we consider that consciousness occurs if an appropriately organized system is able to develop and maintain quantum coherent superposition until a specific ‘objective’ criterion is reached; the coherent system then self-reduces . We contend that this type of objective self-collapse introduces non-computability, an essential feature of consciousness. OR is taken as an instantaneous event -- the climax of a self-organizing process in fundamental space-time -- and a candidate for a conscious Whitehead-like ‘occasion’ of experience. How could an OR process occur in the brain, be coupled to neural activities, and account for other features of consciousness? We nominate an OR process with the requisite characteristics to be occurring in cytoskeletal microtubules within the brain's neurons. (shrink)

Pain is often used as the paradigmatic example of a phenomenal kind with a phenomenal quality common and unique to its instantiations. Philosophers have intensely discussed the relation between the subjective feeling, which unites pains and distinguishes them from other experiences, and the phenomenal properties of sensory, affective, and evaluative character along which pains typically vary. At the center of this discussion is the question whether the phenomenal properties prove necessary and/or sufficient for pain. In the empirical literature, sensory, affective, (...) and evaluative properties have played a decisive role in the investigation of psychophysical correspondence and clinical diagnostics. This paper addresses the outlined philosophical and empirical issues from a new perspective by constructing amultidimensional phenomenal spacefor pain. First, the paper will construe the phenomenal properties of pains in terms of a property space whosestructurereflects phenomenal similarities and dissimilarities by means of spatial distance. Second, philosophical debates on necessary and sufficient properties are reconsidered in terms of whether there is a phenomenal space formed of dimensions along which all and only pains vary. It is concluded that there is no space of this kind and, thus, that pain constitutes aprimitivephenomenal kind that cannot be analyzed entirely in terms of its varying phenomenal properties. Third, the paper addresses theutilityof continued reference to pain and its phenomenal properties in philosophical and scientific discourses. It is argued that numerous insights into the phenomenal structure of pain can be gained that have thus far received insufficient attention. (shrink)

In this paper I lay the foundations for the construction of an affective quality space. I begin by outlining what quality spaces are, and how they have been constructed for sensory qualities across different perceptual modalities. I then turn to tackle four obstacles that an affective quality space might face that would make an affective quality space unfeasible. After showing these obstacles to be surmountable, I propose a number of conditions and methodological constraints that should be satisfied (...) in attempts to construct an affective quality space. Before concluding, I detail the high explanatory pay-off such a project promises. (shrink)

The empirical study of visual space has centered on determining its geometry, whether it is a perspective projection, flat or curved, Euclidean or non-Euclidean, whereas the topology of space consists of those properties that remain invariant under stretching but not tearing. For that reason distance is a property not preserved in topological space whereas the property of spatial order is preserved. Specifically the topological properties of dimensionality, orientability, continuity, and connectivity define “real” space as studied by (...) physics and are the spatial properties that characterize the physical universe as being an integral whole. By contrast the geometrical analysis of VS has taken little cognizance of its topology. Instead such properties have been presupposed a priori rather than being established a posteriori by empirical means, perhaps because these properties are self-evident. Applying the method of coordinative definition expounded by Hans Reichenbach for determining geometrical and topological properties of physical space, it can be shown that VS fulfills the topological criteria of being a “real” space sui generis. Though theorized to be produced by the brain, the topology of VS is not topologically equivalent with the structure and activity of the brain because, as will be shown, the topology of VS cannot be formed from the topology of the brain without tearing and/or cutting and pasting.

The laws which predict how the perceptual quality of figure-ground can be extracted from the most elementary visual signals were discovered by the Gestaltists, and form an essential part of their movement (see especially Metzger, 1930, and Wertheimer, 1923 translated and re-edited by Lothar Spillmann, 2009 and 2012, respectively). Distinguishing figure from ground is a prerequisite for perception of both form and space (the relative positions, trajectories, and distances of objects in the visual field. The human brain has an (...) astonishing capacity for selecting and combining a few critical visual signals to accurately represent both form and space. (shrink)

The isomorphism constraint places plausible limits on the use of third-person evidence to explain color experience but poses no difficulty for functionalists; they themselves argue for just such limits. Palmer's absent qualia claim is supported by neither the Color Machine nor Color Room examples. The nature of color experience depends on relations external to the color space, as well as internal to it.

What is consciousness? Conventional approaches see it as an emergent property of complex interactions among individual neurons; however these approaches fail to address enigmatic features of consciousness. Accordingly, some philosophers have contended that "qualia," or an experiential medium from which consciousness is derived, exists as a fundamental component of reality. Whitehead, for example, described the universe as being composed of "occasions of experience." To examine this possibility scientifically, the very nature of physical reality must be re-examined. We must come (...) to terms with the physics of spacetime-as described by Einstein's general theory of relativity, and its relation to the fundamental theory of matter-as described by quantum theory. Roger Penrose has proposed a new physics of objective reduction: "OR," which appeals to a form of quantum gravity to provide a useful description of fundamental processes at the quantum/classical borderline.hz Within the OR scheme, we consider that consciousness occurs if an appropriately organized system is able to develop and maintain quantum coherent superposition until a specific "objective" criterion (a threshold related to quantum gravity) is reached; the coherent system then self-reduces (objective reduction: OR). We contend that this type of objective self-collapse introduces non-computability, an essential feature of consciousness which distinguishes our minds from classical computers. Each OR is taken as an instantaneous event-the climax of a self-organizing process in fundamental spacetime-and a candidate for a conscious Whitehead "occasion of experience." How could an OR process occur in the brain, be coupled to neural activities, and account for other features of consciousness? We nominate a quantum computational OR process with the requisite characteristics to be occurring in cytoskeletal microtubules within the brain's neurons. In this model, quantum-superposed states develop in microtubule subunit proteins ("tubulins") within certain brain neurons, remain coherent, and recruit more superposed tubulins until a mass-time-energy threshold (related to quantum gravity) is reached..

In a promising working note to the Visible and Invisible, Merleau-Ponty proposes that we understand Being according to topological space – relations of proximity, distance, and envelopment – and move away from an image of Being based on homogeneous, inert Euclidean space. With reference to treatments of cross-sensory perception, color-blindness, and the concept of quale or qualia, I seek to rehearse this shift from Euclidean to topological Being by illustrating how modern science confines color itself to a (...) Euclidean model of color space. I discuss “being as Object” in Merleau-Ponty’s later work before showing how color, and indeed all perception, is reduced to being as Object in the form of “quale”. Next, I address discussions in Merleau-Ponty’s work and contemporary research to illustrate how synesthesia and so-called color-blindness are rendered abnormal by this objectified being of color. Merleau-Ponty’s reading of synesthesia follows directly from his rejection of quale, and his use of color perception serves as a rejection of solipsism. With appeal to his proposed topological model of Being, I conclude by recognizing the problematic nature of synesthesia and color-blindness as being ontological, not psychological.Dans une note de travail, à mon sens décisive, du Visible et l’Invisible, Merleau-Ponty propose que l’on comprenne l’Être à partir de l’espace topologique – relations de proximité, distance et enveloppement – allant à l’encontre d’une l’image de l’Être fondée sur un espace euclidien homogène et inerte. En faisant référence aux traitements de la perception synesthésique, au daltonisme et au concept de quale ou qualia, j’essayerai de décrire ce passage de l’Être euclidien à l’Être topologique en montrant que la science moderne finit par confiner la couleur dans un modèle euclidien d’espace-couleur. J’examinerai « l’Être-objet » dans les derniers écrits de Merleau-Ponty avant de montrer comment la couleur, et plus en général la perception, est réduite à être comme un Objet dans la forme d’un « quale ». Ensuite, en examinant les analyses merleau-pontiennes et les recherches contemporaines, je montrerai comment la synesthésie et le daltonisme sont donc considérés comme anormaux à partir de cette objectivation de la couleur. La lecture que Merleau-Ponty donne de la synesthésie est la conséquence directe de son refus du quale, et l’utilisation qu’il fait de la perception des couleurs sert comme un refus du solipsisme. En faisant appel au modèle topologique de l’Être qu’il propose, je conclurai en constatant que la nature problématique de la synesthésie et du daltonisme est ontologique et non pas psychologique.In una nota di lavoro al Visibile e l’invisibile, Merleau-Ponty propone di comprendere l’Essere a partire da uno spazio topologico – secondo le relazioni di prossimità, distanza e avvolgimento – e abbandona l’immagine di un Essere fondato su uno spazio omogeneo, inerte, euclideo. Facendo riferimento ai trattamenti per le percezioni sinestetiche, al daltonismo e al concetto di quale o qualia, si cercherà di provare questo passaggio da un Essere euclideo a uno topologico, illustrando quanto la scienza moderna tenda a ridurre il concetto stesso di colore a un modello euclideo di spazio-colore. Si esaminerà l’“Essere-oggetto” degli ultimi lavori di Merleau-Ponty, mostrando come il colore, e in realtà la percezione tout court, vengano ridotti a oggetto nella forma di “quale”. Infine, si esaminerà l’opera merleau-pontiana e la ricerca contemporanea al fine di illustrare quanto la sinestesia e il daltonismo siano resi anormali da questa oggettivazione dell’essere del colore. L’interpretazione merleau-pontiana della sinestesia deriva proprio dal suo rifiuto del quale, e il suo uso della percezione del colore funge da rifiuto del solipsismo. Ricorrendo al modello topologico di Essere elaborato da Merleau-Ponty, si conclude riconoscendo che il problema della sinestesia e del daltonismo è, a tutti gli effetti, ontologico e non psicologico.

The dissertation analyzes the theory of "logical space" developed by Ludwig Wittgenstein in his Tractatus Logico-Philosophicus, I show how this idea represents a development of arguments first put forward by Hermann von Helmholtz, the physicist and physiologist. Helmholtz--instead of honouring Kant's distinction between on the one hand time and space, and, on the other, empirical qualia --stretched the Kantian spatial manifold to cover the other qualia as well: the qualia are also organized in manifolds; and (...) this new, extended manifold is the "space" of all possible human experience. He explained this a priori mesh as being a consequence of the physiological constitution of our bodies, and the physical constitution of the world in which they are situated. The subject is enclosed in an inner world whose structure is the network of possible sensation; outside of her is a world of unknown complexity; and separating the two is what Heinrich Hertz called the "no-man's-land" of sense-physiology, a border zone regulating all traffic between the two realms, common to both, yet proper to neither. ;Wittgenstein, in his Tractatus, adapted the picture-theories of Helmholtz and Hertz to his analysis of logic. He too was confronted with the problem of defining a field of possible experience, of possible facts: his analysis of Russell's and Frege's logical theories had led him to the conclusion that the fundamental properties of logic could not be accounted for without assuming such an a priori space. Thus he assimilated Russell's types to the dimensions of a manifold, the elements of which were his Sachverhalte, or elementary facts. The truth-functions of our logic are defined on top of this space: it is the basis on which all symbolic systems, including those of the natural sciences, are erected. (shrink)

The program of “neurophenomenal structuralism” is presented as an agenda for a genuine structuralist neuroscience of consciousness that seeks to understand specific phenomenal experiences as strictly relational affairs. The paper covers a broad range of topics. It starts from considerations about neural change detection and relational coding that motivate a solution of the Newman problem of the brain in terms of spatiotemporal relations. Next, phenomenal quality spaces and their Q-structures are discussed. Neurophenomenal structuralism proclaims a homomorphic mapping of the structures (...) of self-organized neural maps in the brain onto Q-structures, and it will be demonstrated how this leads to a new and special version of structural representationalism about phenomenal content. A methodological implication of neurophenomenal structuralism is that it proposes measurement procedures that focus on the relationships between different stimuli (as, for instance, similarity ratings or representational geometry methods). Finally, it will be shown that neurophenomenal structuralism also has strong philosophical implications, as it leads to holism about phenomenal experiences and serves to reject inverted qualia scenarios.

Several promising approaches have been developed to represent conscious experience in terms of mathematical spaces and structures. What is missing, however, is an explicit definition of what a ‘mathematical structure of conscious experience’ is. Here, we propose such a definition. This definition provides a link between the abstract formal entities of mathematics and the concreta of conscious experience; it complements recent approaches that study quality spaces, qualia spaces, or phenomenal spaces; and it provides a general method to identify and (...) investigate structures of conscious experience. We hope that ultimately this work provides a basis for developing a common formal language to study consciousness. (shrink)

The main interpretive claim of this book is that both Wittgenstein’s mature philosophical method and his much misunderstood critique of private language have their roots in his critique of the misleading metaphor of phenomenal space–that is, the misleading, figurative analogy between physical space, or space simpliciter, and phenomenal space, or the “space” of appearances. His critique of this metaphor extends from his rejection of sense-data (Chapters 2 and 3), to his investigation of the asymmetry between (...) first- and other-person pronouns in conjunction with psychological vocabulary (Chapter 4), to his discussion of noticing aspects (Chapter 3), and, of course, to his revolutionary critique of the privacy of the mental (Chapter 3) and of the related, but more general, misleading metaphor of the inner and the outer. Wittgenstein’s critique of the idea of phenomenal space is, at the same time, the prototype for his new philosophical method–the method of grammatical investigation, which holds that many of the persistent problems of philosophy arise from failing to command a clear view of the grammar of various regions of our language and finding ourselves, as a result, vulnerable to misleading pictures of our mental lives, of our linguistic practices, of mathematics, and of countless fundamental elements of our world view(s), whose misunderstanding is the locus of the traditional problems of metaphysics (Chapter 3). Chapters 5, 6 and 7 argue for the continued relevance of Wittgenstein's critique of the misleading metaphor of phenomenal space by showing how it applies to contemporary discussions of first-person authority, recent attempts to revive sense-datum theories, and the ongoing debate about sensory qualia.

Paul Churchland proposed a conceptual framework for translating reflectance profiles into a space he takes to be the color qualia space. It allows him to determine color metamers of spectral surface reflectances without reference to the characteristics of visual systems, claiming that the reflectance classes that it specifies correspond to visually determined metamers. We advance several objections to his method, show that a significant number of reflectance profiles are not placed into the space in agreement with (...) the qualia solid, and produce two sets of counterexamples to his claim for metamers.

David Hume’s philosophical work presents the reader with a perplexing mix of constructive accounts of empirically guided belief and destructive sceptical arguments against all belief. This book reconciles this conflict by showing that Hume intended his scepticism to be remedial. It immunizes us against the influence of “unphilosophical” causes of belief, determining us to proportion our beliefs to the evidence. In making this case, this book develops Humean positions on topics Hume did not discuss in detail but that are of (...) interest to contemporary philosophers: consciousness and the unity of consciousness, temporal experience, visual spatial perception, the experience of colour and other qualia, objective experience, and spatially extended minds. It also challenges currently accepted interpretations of Hume’s views on the finite divisibility of space and time, vacuum, the duration of unchanging objects, and identity over time. It deals with criticisms of Hume that were raised by his contemporaries, notably by Thomas Reid, draws attention to earlier seventeenth‑ and eighteenth‑century work that has bearing on the interpretation of Hume’s thought, and compares Hume’s achievements with those of later nineteenth‑century psychologists and philosophers.

One of the main challenges in consciousness research is widely known as the hard problem of consciousness. In order to tackle this problem, I utilize an approach from theoretical physics, called stochastic electrodynamics (SED), which goes one step beyond quantum theory and sheds new light on the reality behind matter. According to this approach, matter is a resonant oscillator that is orchestrated by an all-pervasive stochastic radiation field, called zero-point field (ZPF). The properties of matter are not intrinsic but acquired (...) by dynamic interaction with the ZPF, which in turn picks up information about the material system as soon as an ordered state, i.e., a stable attractor, is reached. I point out that these principles apply also to macroscopic biological systems. From this perspective, long-range correlations in the brain, such as neural gamma synchrony, can be interpreted in terms of order phenomena induced and stabilized by the ZPF, suggesting that every attractor in the brain goes along with an information state in the ZPF. In order to build the bridge to consciousness, I employ additional input from Eastern philosophy. From a comparison between SED and Eastern philosophy I draw the conclusion that the ZPF is an appropriate candidate for the substrate of consciousness, implying that information states in the ZPF are associated with conscious states. On this basis I develop a conceptual framework for consciousness that is fully consistent with physics, neurophysiology, and Eastern philosophy. I argue that this conceptual framework has many interesting features and opens a door to a theory of consciousness. Particularly, it solves the problem of how matter and consciousness communicate in a causally closed functional chain, it gives a physical grounding to existing approaches regarding the connection between consciousness and information, and it gives clear direction to future models and experiments.

The Hurvich-Jameson (H-J) opponent-process network offers a familiar account of the empirical structure of the phenomenological color space for humans, an account with a number of predictive and explanatory virtues. Its successes form the bulk of the existing reasons for suggesting a strict identity between our various color sensations on the one hand, and our various coding vectors across the color-opponent neurons in our primary visual pathways on the other. But anti-reductionists standardly complain that the systematic parallels discovered by (...) the H-J network are just empirical correspondences, constructed post facto, with no predictive or explanatory purchase on the intrinsic characters of qualia proper. The present paper disputes that complaint, by illustrating that the H-J model yields some novel and unappreciated predictions, and some novel and unappreciated explanations, concerning the qualitative characters of a considerable variety of color sensations possible for human experience, color sensations that normal people have almost certainly never had before, color sensations whose accurate descriptions in ordinary language appear semantically ill-formed or even self-contradictory. Specifically, these "impossible" color sensations are activation-vectors (across our opponent-process neurons) that lie inside the space of neuronally possible activation-vectors, but outside the central 'color spindle' that confines the familiar range of sensations for possible objective colors. These extra-spindle chimerical-color sensations correspond to no reflective color that you will ever see objectively displayed on a physical object. But the H-J model both predicts their existence and explains their highly anomalous qualitative characters in some detail. It also suggests how to produce these rogue sensations by a simple procedure made available in the latter half of this paper. The relevant color plates will allow you to savor these sensations for yourself. (shrink)

Definitions of phenomenal types (Nelson Goodman’s definition of qualia, Sydney Shoemaker’s phenomenal types, Austen Clark’s physicalist theory of qualia) imply that numerically distinct experiences can be type-identical in some sense. However, Goodman also argues that objects cannot be replicated in respect of continuous and densely ordered types. In that case, how can phenomenal types be defined for sizes, shapes and colours, which appear to be continuously ordered types? Concentrating on size, I will argue for the following points. (§2) (...) We cannot deny the possibility of replication in respect of dense types, because this would imply that particulars have determinable sizes, shapes and colours. (§3) Phenomenal sizes and shapes are determinable types; objective, or super-determinate, sizes and shapes are unknowable. (§4) We can define and know, prior to verification, groupings of objective sizes for which indiscriminability is transitive. (§5) Phenomenal identity has to be defined on the basis of these transitive groupings, because finer-grained criteria (such as Goodman’s) lead to definition of objective identity. The quality space of phenomenal types consists of overlapping but not dense types, and this prevents a collapse of phenomenal types. (shrink)

Bergson’s model of time (1889) is perhaps the proto-phenomenological theory. It is part of a larger model of mind (1896) which can be seen in modern light as describing the brain as supporting a modulated wave within a holographic field, specifying the external image of the world, and wherein subject and object are differentiated not in terms of space, but of time. Bergson’s very concrete model is developed and deepened with Gibson’s ecological model of perception. It is applied to (...) the problems of consciousness, direct realism, qualia and illusions. The model implies an entirely different basis for memory and cognition, and a brief overview is given for the basis of direct memory, compositionality and systematicity. (shrink)

Resumo Os Qualia, ou são “entidades espaciais” – ou seja, estão localizados no espaço como os objectos físicos –, ou não são “entidades espaciais”. Então, o dualismo deve alegar que ou os qualia não-físicos são entidades espaciais, ou que eles não o são. Contudo, qualquer resposta é problemática. Se os qualia não-físicos não são entidades espaciais, então, é difícil de conceber como podem ser atribuídos a cérebros particulares, individualizados uns dos outros, e assim por diante. Mas se (...) os qualia não-físicos são entidades espaciais, então, surgem outros problemas, por exemplo, torna-se difícil perceber como poderíamos ter então um acesso privilegiado a eles. Dada uma ou outra opção, o dualismo é problemático. Portanto, o dualismo é problemático. Palavras-chave : argumento do conhecimento, consciência, dualismo, fisicalismo, problema mente-corpo, qualiaQualia are either “spatial entities” – i.e., they are located in space like physical objects – or they are not. So, dualism must claim that either non-physical qualia are spatial entities or they are not. But either answer is problematic. If non-physical qualia are not spatial entities, then it is difficult to see how they can be attributed to particular brains, individuated from one another, and so on. But if non-physical qualia are spatial entities, then other problems arise, e.g., it is difficult to see how we could have privileged access to them. Given either option, dualism is problematic. Therefore, dualism is problematic. Keywords : consciousness, dualism, knowledge argument, mind-body problem, Physicalism, Qualia. (shrink)

Consciousness is arguably the greatest mystery in science, still being unsolved after millennia of thinking. This book is one further attempt at trying to bring new insights regarding consciousness. While certainly the mystery will continue, the ideas in this book will raise awareness regarding an aspect of the phenomenology of consciousness that has been overlooked by past thinkers, and that is the emergent structure of consciousness, which in the end will be shown to be realized by the nature of self-reference (...) of looking-back-at-itself. The great take-away from appreciating the true nature of self-refence would be the need to switch to an unformal way of thinking in doing science if the problem of consciousness is to be resolved. To unformal way of thinking means abandoning the desire to have clearly defined entities in our theories, like “energy” or “space-time” or “spin”, and instead allow for entities that cannot be formalized, to be responsible for the workings of the world. We will slowly see as the book unfolds why the need for unformal way of thinking arises. -/- Regarding the presentation style, the book is both a popular book and a rigorous presentation that goes into thorough phenomenological analyses of consciousness. The reason is that our lives themselves are both familiar and the very nature of existence. As opposed to other writings that use a more technical approach, the philosophy of this book is that a theory of consciousness should focus more on the most mundane manifestations of consciousness, like the redness of an apple or the warmish feeling of cup of hot chocolate, in order to give a clearer understanding of consciousness. Therefore, the book is full of everyday examples of conscious experiences that the reader can relate to and use them to gain deeper insights into the workings of consciousness. In the same way that LHC is the laboratory of physicists, introspection is our own laboratory, the advantage of introspection over LHC being that it is accessible to anyone. Every person can gain a deep knowledge of consciousness by simply paying close attention to his own experiences. Of course, the difficulty arises because of the huge diversity of our experiences and this might raise an apparent initial obstacle of where one is to begin his understanding of consciousness. The book is designed as a guide through the complexities of everyday experiences in the direction of sorting them out in general and clear ways of thinking, showing that consciousness needs not be something that difficult to understand if only the proper attention is given to our experiences. -/- Therefore, the book starts with a chapter about qualia, where through many examples it is shown to be a form of meaning. Then the reader is familiarized with the Self through simple thought experiments that lead to the conclusion of the unicity of the Self, and then a further logical analysis that shows the eternal existence of the Self. After these initial familiarizations with consciousness, the book goes into its core subject, that being the emergent phenomenology, in which it will be shown how consciousness is structured on a holarchy of levels and how ultimately this structuring is a result of self-reference looking-back-at-itself, consciousness being shown to be possible only because of the unformalizable nature of self-reference.

Computationalism, a specie of functionalism, posits that a mental state like pain is realized by a ‘core’ computational state within a particular causal network of such states. This entails that what is realized by the core state is contingent on events remote in space and time, which puts computationalism at odds with the locality principle of physics. If computationalism is amended to respect locality, then it posits that a type of phenomenal experience is determined by a single type of (...) computational state. But a computational state, considered by itself, is of no determinate type—it has no particular symbolic content, since it could be embedded in any of an infinite number of algorithms. Hence, if locality is respected, then the type of experience that is realized by a computational state, or whether any experience at all is realized, is under-determined by the computational nature of the state. Accordingly, Block’s absent and inverted qualia arguments against functionalism find support in the locality principle of physics. If computationalism denies locality to avoid this problem, then it cannot be considered a physicalist theory since it would entail a commitment to phenomena, like teleological causation and action-at-a-distance, that have long been rejected by modern science. The remaining theoretical alternative is to accept the locality principle for macro events and deny that formal, computational operations are sufficient to realize a phenomenal mental state.

: According to a consensus of psycho-physiological and philosophical theories, color sensations (or qualia) are generated in a cerebral "space" fed from photon-photoreceptor interaction (producing "metamers") in the retina of the eye. The resulting "space" has three dimensions: hue (or chroma), saturation (or "purity"), and brightness (lightness, value or intensity) and (in some versions) is further structured by primitive or landmark "colors"—usually four, or six (when white and black are added to red, yellow, green and blue). It (...) has also been proposed that there are eleven semantic universals—labeling the previous six plus the "intermediaries" of orange, pink, brown, purple, and gray. There are many versions of this consensus, but they all aim to provide ontological, epistemological and semantic blueprints for the brute fact of the reality of color ordained by Nature (evolution). In contrast to this consensus, we have argued that "seeing color" is not a matter of light waves impacting on our eyes, producing sensations to be categorized and labeled in the "color space" in the brain. While electrochemical events may unproblematically be regarded as the causal precondition for seeing color, the reception of sensations in "the color space" as semantically labeled natural categories, kinds, or information, is a "just so" story: it is Wittgenstein's beetle in a box. In contrast we consider that the authority of this consensus might better be regarded not as the result of the truth-tracking of nature, but as the sociohistorical outcome of philosophical presuppositions, scientific theories, experimental practices, technological apparatus, and their feed forward into the lifeworld. The question we shall therefore explore is whether, or to what extent, we ourselves are changed, as the conditions of production of color science change. Thus we are doing a kind of anthropology at two levels: of color science itself (and its effect on our own lifeworld), and of those studied by the "anthropology of color". As befits this stance we are agnostic about the theoretical entities of color science (cf. van Fraassen 2001), and within this new context, we propose to cross-cut object-and-subject, organism-and-environment (the bedrock of color science) in socio-historical ways. Our approach is in part inspired by, but not the same as, that of Gibson, in that we wish to pursue the notion of "social affordances" (Burmudez 1995). We suggest that color has become a naturalization through science-based technologies, which, through praxes and materializations, have become the perceptual and cultural entities that structure experience and understanding in the lifeworld. It is this naturalization that we shall refer to and characterize as "the historically inflected exosomatic organ". Consequently we shall explore the historical ontology of "color" without assuming an underlying biological constant (Dupré 2001). In part 1 we show the flimsiness of the evidence for the three dimensions of color, borrowed from physics, and fine-tuned to a "standard observer" (a "spectral creature" with a phenomenal "color space"). In part 2 we address the structuring of hue through the development of color circles and color spaces. This is followed by a review of the evidence for unique hues. Again the evidence is shown to be flimsy. We then show that an isolated domain of color is a particular kind of model, not a "natural given". In part 3, after reviewing what is referred to as "the isomorphy thesis," we discuss the exemplary case study of Berlin and Kay (1969). This illustrates the pull of stadial models presupposed by their evolutionary theory of color language. The Berlin and Kay paradigm proposes that American English color terms are incorrigible and can provide the universal metalanguage. We conclude by presenting an alternative account, namely that we ourselves are changed as the conditions of production of color science change. We argue that it is better to regard "seeing-color" as a historically inflected exosomatic organ that provides social affordances for those trained to grasp them. (shrink)

The paper defends the philosophical method of "regimentation" by example, especially in relation to the theory of mind. The starting point is the Place-Smart after-image argument: A green after-image will not be located outside the skull, but if we cracked open your skull, we won't find anything green in there either. (If we did, you'd have some disturbing medical news.) So the after-image seems not to be in physical space, suggesting that it is non-physical. In response, I argue that (...) the green blob is a fictional object, while assuming a weak sort of realism about fictional objects (where they exist as mind-dependent objects). This view can look like dualism, however, but I try to interpret it not as implying metaphysical dualism, but rather as reflecting a dualism of theory. Roughly, there can be a theory of mind-independent objects, and a theory of mind-dependent objects. Yet there are principled reasons why we cannot integrate the two into a consistent whole, for reasons related to Russell's vicious circle principle. Most of the paper motivates this by an analogy between the physicalist's theory of the world, and drawing a map with a complete representation of the map itself. Regimentation unearths the inconsistencies that arise, when trying to represent as part of a model the very representations used to define the model. (shrink)

Can qualia be analyzed by theories that contain only non-qualitative terms? A host of philosophers including Block, Levine, Nagel, and Jackson have argued that, in principle, they cannot. And yet psychophysicists have advanced explanations that seem to account for sensory appearances in terms of the operations of nervous systems. Here are some examples: Mach bands, the assimilation effect, and the Hermann grid illusion all have to do with the look of things, and all are routinely thought to be a (...) consequence of the structure of visual receptive fields. Simultaneous contrast and auditory tuning—both perceptual effects—are lateral inhibition phenomena. That television sets with only three phosphor colors can replicate natural scenes with thousands of distinguishable colors is due to our eyes having just three photopigments. The difference between a three-type receptoral configuration and an array of thousands of receptors with distinct responses accounts for the fact that hues form a closed loop in color space, whereas there are no closed pitch loops in auditory space.

Mark Jago presents an original philosophical account of meaningful thought: in particular, how it is meaningful to think about things that are impossible. We think about impossible things all the time. We can think about alchemists trying to turn base metal to gold, and about unfortunate mathematicians trying to square the circle. We may ponder whether God exists; and philosophers frequently debate whether properties, numbers, sets, moral and aesthetic qualities, and qualia exist. In many philosophical or mathematical debates, when (...) one side of the argument gets things wrong, it necessarily gets them wrong. As we consider both sides of one of these philosophical arguments, we will at some point think about something that’s impossible. Yet most philosophical accounts of meaning and content hold that we can’t meaningfully think or reason about the impossible. -/- In The Impossible, Jago argues that we often gain new information, new beliefs, and, sometimes, fresh knowledge through logic, mathematics, and philosophy. That is why logic, mathematics, and philosophy are useful. We therefore require accounts of knowledge and belief, of information and content, and of meaning which allow space for the impossible. Jago’s aim in this book is to provide such accounts. He gives a detailed analysis of the concept of hyperintensionality, whereby logically equivalent contents may be distinct, and develops a theory in terms of possible and impossible worlds. Along the way, he provides a theory of what those worlds are and how they feature in our analysis of normative epistemic concepts: knowledge, belief, information, and content. (shrink)

A full appreciation for Ernst Mach's doctrine of the economy of thought must take account of his direct realism about particulars (elements) and his anti-realism about space-time laws as economical constructions. After a review of thought economy, its critics and some contemporary forms, the paper turns to the philosophical roots of Mach's doctrine. Mach claimed that the simplest, most parsimonious theories economized memory and effort by using abstract concepts and laws instead of attending to the details of each individual (...) event or experiment. For Mach, the individual case never truly repeated in all of its uniqueness, nor was all of the individual detail of a physical element adequately captured in abstract laws and schemata, however necessary these were for the pursuit of science. As can be shown from specific passages, some already published, some not, Mach's elements included physical qualia in nature similar to Russell's unsensed sensibilia, which existed even where there were no conscious observers. An argument will be presented to make the case that Mach believed in the mind-independent elements from the 1870s on, while other aspects of his thought evolved over time; I have thus dated the references to reflect this historical progression. I concentrate on Mach's ontology, as it bears on economy of thought, not his epistemology per se, which might well have been restricted to observable elements/sensations. After his own conversion to neutral monism, in the 1920s, Bertrand Russell echoed Mach's call for a 'future science' capable of handling the 'intrinsic character' of qualitative data directly without the excessive abstraction of physics.
