Representationalist theories of sensory experience are often thought to be vulnerable to the existence of apparently non-representational differences between experiences in different sensory modalities. Seeing and hearing seem to differ in their qualia, quite apart from what they represent. The origin of this idea is perhaps Grice’s argument, in “Some Remarks on the Senses,” that the senses are distinguished by “introspectible character.” In this chapter I take the Representationalist side by putting forward an account of sense modalities which is consistent (...) with that view and yet pays due regard to the intuition behind Grice’s argument. Employing J.J. Gibson’s distinction between exploratory and performatory behaviour, I point to a proprioceptive element in perceptual experience, and identify this as crucial in any account of what makes a particular way of perceiving a sense modality.

Born in 1943, Frank Jackson took Mathematics and Philosophy at the University of Melbourne. Upon graduation, in 1967 he taught for one year at the University of Adelaide before returning to Melbourne for a lectureship appointment at La Trobe University. While at La Trobe, Jackson published his first book (also his doctoral thesis), Perception: A Representative Theory (1977b). In 1978 he succeeded his father, A. C. (‘Camo’) Jackson, to the chair of Philosophy at Monash University, before moving to Canberra in (...) 1986 to succeed J. J. C. Smart as Head of the Philosophy Program in the Research School of Social Sciences (RSSS). Jackson delivered the John Locke Lectures at Oxford University in 1994–95, only the second Australian to do so, and has delivered many other named lectures. At the Australian National University (ANU) he also served for some time as Director of the Institute of Advanced Studies and other high level administrative positions, for which, in addition to his singular contributions to philosophy, he was awarded the Order of Australia in 2006 by the Australian Government. He is currently on a joint appointment between Princeton University and La Trobe University, and continues to spend considerable time at ANU. (shrink)

If we assume that the operation of each sense modality constitutes a different experience – a visual experience, an auditory experience, etc – we are faced with the problem of how those distinct experiences come together to form a unified perceptual encounter with the world. Michael Tye has recently argued that the best way to get around this problem is to deny altogether that there are such things as purely visual (and so forth) experiences. Here I aim to show not (...) simply that Tye’s proposed solution fails, but that its failure is highly instructive because it allows us to see that the transparency thesis, which lies at the heart of the case against qualia, and of most representationalist theories of experience, is more problematic than is often supposed.

Higher-order theories of consciousness, such as those of Armstrong, Rosenthal and Lycan, typically distinguish sharply between consciousness and phenomenal character, or qualia. The higher-order states posited by these theories are intended only as explanations of consciousness, and not of qualia. In this paper I argue that the positing of higher-order perceptions may help to explain qualia. If we are realists about qualia, conceived as those intrinsic properties of our experience of which we are introspectibly aware, then higher-order perception might have (...) an explanatory role as the means by which we are aware of these properties. This would also allow us to treat qualia as the inner appearances resulting from inner perceptions, and therefore to treat them as intentional objects. (shrink)

Stephen Kershnar (2004) recently argues that under its most plausible interpretation, equality of opportunity is simply not something worth pursuing; at least, not for itself. In this paper I try to show that even if we accept Kershnar's characterisation of equality of opportunity in terms of weighted aggregate chances, none of his objections succeed. Opportunities, not outcomes, are the appropriate focus of EO advocates; hedonic treadmills are irrelevant to the issue; we do not need to assume general equality in some (...) attribute to ground equality of opportunity; finally, it is possible to show that it is permissible to promote EO at some cost to other independent values.

The representational theory of phenomenal experience is often stated in terms of a supervenience thesis: Byrne recently characterises it as the thesis that “there can be no difference in phenomenal character without a difference in content”, while according to Tye, “[a]t a minimum, the thesis is one of supervenience: necessarily, experiences that are alike in their representational contents are alike in their phenomenal character.” Consequently, much of the debate over whether representationalism is true centres on purported counter-examples – that is (...) to say, purported failures of supervenience. The refutation of putative counter-examples has been, it seems to me, by and large successful. But there is a certain class of these for which the representationalist response has been something less than completely convincing. These are the cross-modality cases. I will explain what I mean, and then argue that the response in question is not only unconvincing but actually undermines the representationalist position. (shrink)

This paper advances the thesis that sensory concepts have as a semantic component the first person indexical.
