Inverted sensation arguments such as the inverted spectrum thought experiment are often criticized for relying on an unconstrained notion of 'qualia'. In reply to this criticism, 'qualia-free' arguments for inversion have been proposed, in which only physical changes happen: inversions in the world, such as the replacement of surface colors by their complements, and a rewiring of peripheral input cables to more central areas in the nervous system. I show why such constrained inversion arguments won't work. The first problem is that the world lacks the symmetry required to invert physical properties in the way required. The second problem concerns 'rewiring'. Empirical evidence indicates that the rewirings are either impossible, or would not result in an inversion of sensation. I propose the deeper reason for the failure of constrained inversion arguments lies in the fact that sensations are not properties of brain states, but spread into the world and the body.

Color experience is structured. Some ?unique? colors (red, green, yellow, and blue) appear as ?pure,? or containing no trace of any other color. Others can be considered as a mixture of these colors, or as ?binary colors.? According to a widespread assumption, this unique/binary structure of color experience is to be explained in terms of neurophysiological structuring (e.g., by opponent processes) and has no genuine explanatory basis in the physical stimulus. The argument from structure builds on these assumptions to argue that colors are not properties of surfaces and that color experiences are neural processes without environmental counterparts. We reconsider the argument both in terms of its logic and in the light of recent models in vision science which point at environment-involving patterns that may be at the basis of the unique/binary structure of color experience. We conclude that, in the light of internal and external problems which arise for it, the argument from structure fails

  Susan Hurley has attacked the ''Duplication Assumption'', the assumption thatcreatures with exactly the same internal states could function exactly alike inenvironments that are systematically distorted. She argues that the dynamicalinterdependence of action and perception is highly problematic for the DuplicationAssumption when it involves spatial states and capacities, whereas no such problemsarise when it involves color states and capacities. I will try to establish that theDuplication Assumption makes even less sense for lightness than for some ofthe spatial cases. This is due not only to motor factors, but to the basic physicalasymmetry between black and white. I then argue that the case can be extendedfrom lightness perception to hue perception. Overall, the aims of this paper are:(1) to extend Susan Hurley''s critique of the Duplication Assumption; (2) to argueagainst highly constrained versions of Inverted Spectrum arguments; (3) to proposea broader conception of the vehicle for color perception

Consider Susan Hurley's depiction of mainstream views of the mind: "The mind is a kind of sandwich, and cognition is the filling" (p. 401). This particular sandwich (with perception as the bottom loaf and action as the top loaf) tastes foul to Hurley, who devotes most of "Consciousness in Action" to a systematic and sometimes extraordinarily detailed critique of what has otherwise been dubbed "classical" models of the mind. This critique then provides the basis for her alternative proposal, in which perception, action and environment are deeply intertwined

Two kinds of vision science are distinguished: a representational versus a nonrepresentational one. Seeing in the former is conceived of as creating an internal replica of the external world, while in the latter seeing is taken to be a process of active engagement with the environment. The potential of each theory for elucidating artistic creation and aesthetic appreciation is considered, necessarily involving some comments on visual consciousness. This discussion is intended as a background against which various themes of the papers light up.

Smell 'sensations' are among the most mysterious of conscious experiences, and have been cited in defense of the thesis that the character of perceptual experience is independent of the physical events that seem to give rise to it. Here we review the scientific literature on olfaction, and we argue that olfaction has a distinctive profile in relation to the other modalities, on four counts: in the physical nature of the stimulus, in the sensorimotor interactions that characterize its use, in the structure of its intramodal distinctions and in the functional role that it plays in people's behaviour. We present two thought experiments in which we detail what would be involved in transforming sounds into smells, and also smells into colours. Through these thought-experiments, we argue that the experiential character of smell derives precisely from the structural features of olfaction, and that an embodied account of olfactory phenomenology is called for.

In this paper, we present an account of phenomenal consciousness. Phenomenal consciousness is experience, and the problem of phenomenal consciousness is to explain how physical processes?behavioral, neural, computational?can produce experience. Numerous thinkers have argued that phenomenal consciousness cannot be explained in functional, neural or information-processing terms (e.g. Block 1990, 1994; Chalmers 1996). Different arguments have been put forward. For example, it has been argued that two individuals could be exactly alike in functional/computational/behavioral measures, but differ in the character of their experience. Though such persons would behave in the same way, they would differ in how things felt to them (for example, red things might give rise to the experience in one that green things give rise to in the other). Similarly, it has been held that two individuals could be functionally/computationally/behaviorally alike although one of them, but not the other, is a mere zombie, that is, a robot-like creature who acts as if it has experience but is in fact phenomenally unconsciousness. For any being, it has been suggested, the question whether it has experience (is phenomenally conscious) cannot be answered by determining that it is an information-processor of this or that sort. The question is properly equivalent to the question whether there is anything it is like to be that individual (Nagel 1974). Attempts to explain consciousness in physical or information-processing terms sputter: we cannot get any explanatory purchase on experience when we try to explain it in terms of neural or computational processes. Once a particular process has been proposed as an explanation, we can then always reasonably wonder, it seems, what it is about that particular process that make it give rise to experience. Physical and computational mechanisms, it seems, require some further ingredient if they are to explain experience. This explanatory shortfall has aptly been referred to as "the explanatory gap" (Levine 1983)..

Music raises many problems for those who would understand it more deeply. It is rooted in time, yet timeless. It is pure form, yet conveys emotion. It is written, but performed, interpreted, improvised, transcribed, recorded, sampled, remixed, revised, rebroadcast, reinterpreted, and more. Music can be studied by philosophers, psychologists, sociologists, mathematicians, biologists, computer scientists, neuro-scientists, critics, politicians, promoters, and of course musicians. Moreover, no single perspective seems either sufficient or invalid. This situation is not so different from that of other arts, but perhaps more intense, due to the pervasiveness of pop, the inaccessability of much contemporary classical music, the strong cultural associations of many styles , the infusions of technology, and the combination with lyrics

There is a popular view on depiction which holds that convincingly realistic paintings depict their subjects through evoking in the spectator the illusion of seeing these very subjects face to face. There is, as it were, an exact 'match' between the visual experience of seeing something in a picture and the corresponding visual experience one would entertain if one were to stand in front of the real thing. This view, which we shall call 'illusionism', supports the widespread assumption that some kinds of pictures -- notably post-Renaissance perspective paintings -- provide the correct, 'natural' way to depict physical space because they capture the way the visual system enables one to see the world. The most notable defence of illusionism has been offered by Ernst Gombrich. In his Art and Illusion, Gombrich (1960) argues that the development of Western art consists in a series of discoveries about the nature of visual perception that eventually lead to pictorial techniques that are able to elicit illusionary visual experiences on part of the spectator and thus reach the perfection of naturalistic representation.
