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.

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)
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.

Dintre fenomenele mentale, nici unul nu pare să reziste atât de bine explicaţiei precum conştiinţa. Parţial, dificultatea se datorează faptului că folosim termenul „conştient” şi alţii înrudiţi să dea seama de anumite fenomene distincte ale căror legături nu sunt întotdeauna clare. Iar acest lucru duce adesea la amestecarea acestor fenomene distincte. De aceea, orice încercare de a explica conştiinţa trebuie să înceapă prin a distinge diferitele lucruri pe care le numim conştiinţă. Un astfel de fenomen este strâns legat de simplul (...) fapt de a fi în stare de veghe. Noi descriem oamenii şi alte fiinţe ca fiind conştienţi atunci când sunt în stare de veghe şi sistemele lor senzoriale sunt receptive într-un mod normal pentru o stare de veghe. Numesc acest fenomen conştiinţă a fiinţei. În acest sens, conştiinţa este o chestiune biologică, constând în aceea că o fiinţă nu este inconştientă – adică, aproximativ starea opusă somnului sau KO-ului. Însă noi folosim termenul „conştiinţă” şi pentru alte fenomene care par mult mai greu accesibile înţelegerii şi explicaţiei. Astfel, distingem nu numai între fiinţe conştiente şi inconştiente, ci şi între stări mentale ce sunt conştiente şi cele ce nu sunt. Voi numi această a doua proprietate conştiinţă de stare. Este bine cunoscut faptul că nu toate stările mentale sunt conştiente. Stări intenţionale precum credinţele şi dorinţele apar în mod vădit fără a fi conştienţi.1 Şi, în ciuda unor diferenţe de opinie asupra chestiunii, voi argumenta că acelaşi lucru este adevărat şi în privinţa stărilor senzoriale precum durerile şi senzaţiile de culoare. Asemenea stări nu numai că pot apărea în mod inconştient, dar adesea o şi fac.2 Deşi conştiinţa fiinţei şi conştiinţa de stare sunt proprietăţi distincte, este foarte posibil să fie legate în diferite moduri. Poate că, de exemplu, fiinţele trebuie ele însele să fie conştiente pentru ca oricare stare mentală a lor să fie conştientă, deşi dacă visurile obişnuite sunt vreodată stări conştiente, ele constituie contraexemple ale acestei generalizări.3 Oricum ar sta lucrurile în această privinţă, proprietatea conştiinţei fiinţei este relativ neproblematică. Putem constata aceasta luând în considerare fiinţe mai puţin înzestrate mental decât noi ale căror stări mentale nu sunt niciodată conştiente, nici măcar atunci când sunt în stare de veghe.4 Toate stările lor mentale sunt asemănătoare stărilor mentale inconştiente în care ne aflăm atunci când suntem trezi..
