Some philosophers have regarded the connection between hues and certain arousal or affective qualities as so intimate as to make them inseparable, and this “necessary concomitance view” has been invoked to defend functionalism against arguments based on inverted spectra. Support for the necessary concomitance view has sometimes been thought to accrue from experiments in psychology. This paper examines three experiments, two of which apparently offer support for the view. It argues that careful consideration of these experiments undermines this appearance of (...) support. General lessons are drawn concerning the problem that individual differences present for functionalism, and the difficulty of supporting strong conclusions about concomitance by using the methods of experimental psychology.

endorsed one kind of inverted spectrum hypothesis and rejected another. This paper argues that the kind of inverted spectrum hypothesis that Wittgenstein endorsed is the thin end of the wedge that precludes a Wittgensteinian critique of the kind of inverted spectrum hypothesis he rejected. The danger of the dangerous kind is that it provides an argument for qualia, where qualia are contents of experiential states which cannot be fully captured in natural language. I will pinpoint the difference between the innocuous (...) and dangerous scenarios that matters for the argument for qualia, give arguments in favor of the coherence and possibility of the dangerous scenario, and try to show that some standard arguments against inverted spectra are ineffective against the version of the dangerous scenario I will be advocating. The leading idea of the paper is that an argument for qualia based on spectrum inversion does not require that the inversion be behaviorally indistinguishable. At one crucial point, I will rely on a less controversial version of an argument I gave in Block. Wittgenstein's views provide a convenient starting point for a paper that is much more about qualia than about Wittgenstein. (shrink)

It is argued that the explanatory gap argument, according to which it is fundamentally impossible to explain qualitative mental states in a physicalist theory of mind, is unsound. The main argument in favour of the explanatory gap is presented, which argues that an identity statement of mind and brain has no explanatory force, in contrast to "normal" scientific identity statements. Then it is shown that "normal" scientific identity statements also do not conform to the demands set by the proponent of (...) the explanatory gap. Rather than accept all such gaps, it is argued that we should deny the explanatory gap in a physicalist theory of mind. (shrink)

Empirical arguments for materialism are highly circumstantial—based, as they are, upon inductions from our knowledge of the physical and upon the fact that mental phenomena have physical correlates, causes and effects. However, the qualitative characteristics of first-person conscious experience are empirically distinct from uncontroversially physical phenomena in being—at least on our present knowledge—thoroughly resistant to the kind of abstract, formal description to which the latter are always, to some degree, readily amenable. The prima facie inference that phenomenal qualities are, most (...) probably, non-physical may be resisted either by denying their existence altogether or by proposing that they are properties of some peculiar sort of mysterious physical complexity, located, for example, within the functioning of the brain. It is argued here, however, that the first, eliminative hypothesis is empirically absurd—while the second is extravagant, vague, ad hoc and (for various additional reasons) profoundly implausible. Taken together, these considerations provide a compelling empirical case against materialism—yet its converse, mentalism, is usually regarded as subject to serious difficulties of its own. I conclude by suggesting empirical and theoretical desiderata, respectively, for the vindication of materialism and alternatively, for the development and defense of a potentially robust and viable mentalist theory of consciousness.

Qualia inversion thought experiments are ubiquitous in contemporary philosophy of mind. The most popular kind is one or another variant of Locke's hypothetical case of.

Remarks on the Relations between Neurophysiology and Psychology. In the last decades of Analytical Philosophy, contributions to the so-called mind-body-problem have been suffering by several serious methodological misunderstandings: they have failed, for instance, to distinguish between explanations of particular and strictly general properties and between two important senses of existential statements; and they have overlooked the role conceptual explanations play in the development of science. Changing our methodological premisses, we should be able to put questions like that of the relation (...) between physiological and psychological phenomena in a new way - and we should be able to see that such newly understood questions allow answers which evade the pitfalls of both reductionist and holistic positions. The paper tries to illustrate and to defend these contentions by reference to a very elementary example: the rational re-building of our concepts to identify behaviour by which a subject controls the position of his body in space.

A major part of the mind–body problem is to explain why a given set of physical processes should give rise to perceptual qualities of one sort rather than another. Colour hues are the usual example considered here, and there is a lively debate as to whether the results of colour vision science can provide convincing explanations of why colours actually look the way they do. The internal phenomenological structure of colours is considered here in some detail, and a comparison is (...) drawn with sounds and their synthesis. This paper examines the type of explanation that is needed, and it is concluded that it does not have to be reductive to be effective. What needs to be explained more than anything is why inverted hue scenarios are more intuitive than other sensory inversions: and the issue of physicalism versus dualism is argued to be of only marginal relevance.

In this paper I explicate a technique which can be used to make subtle relational features of experience more evident to awareness. Results of this method could be employed to diffuse one intuition that drives the common critique of functionalist-information theoretic accounts of mind that "qualia" cannot be exhaustively characterized in information theoretic-functional terms. An intuition that commonly grounds this critique is that the qualitative aspects of experience do not entirely appear in consciousness as informational-functional structures. The first section of (...) the paper is a schematic overview of nature of the qualitative and the problem that qualia are taken to create for information theoretic-functionalist theories of mind. §2 contains a précis of the concept of different levels of functional scale in mental activity that was developed by Armstrong and the Churchlands and that is needed to interpret (possible) results of the proposed experiment. In §3, I outline a method whereby analogies would be generated between purely relational forms, structures, configurations, etc. and purely qualitative aspects of experience. These analogies would be created by subjects through forced choice selection of presented images of structures that "most resembled" a pure quality. Repeated choices would then be shaped by a genetic program into the structural configuration that "most resembled" the pure quality. The final section of the paper explores how consistent, reliable results from the experiment would make information-theoretic functionalism more intuitively plausible in spite of the "fact" that the qualitative aspects of experience do not immediately appear as entirely relational/structural.

It is often claimed, following Joseph Levine, that there is an ‘explanatory gap’ between ordinary physical facts and the way we perceive things, so that it is impossible to explain, among other things, why colours actually look the way they do. C.L. Hardin, by contrast, argues that there are sufficient asymmetries between colours to traverse this gap. This paper argues that the terms we use to characterize colours, such as ‘warm’ and ‘cool’, are not well understood, and that we need (...) to understand the neurological basis for such associations if we are even to understand what is fully meant by saying, for example, that red is a warm colour. This paper also speculates on how Hardin’s strategy can be generalized. A PowerPoint presentation that depicts inverted colour qualia is attached as an appendix. (shrink)
