Brain activity determines which relations between objects in the environment are perceived as differences and similarities in colour, smell, sound, etc. According to selectionism, brain activity does not create those relations; it only selects which of them are perceptually available to the subject on a given occasion. In effect, selectionism entails that perceptual experience is diaphanous, i.e. that sameness and difference in the phenomenal character of experience is exhausted by sameness and difference in the perceived items. It has been argued (...) that diaphaneity is undermined by phenomenological considerations and empirical evidence. This paper considers five prominent arguments of this sort and shows that none of them succeeds. (shrink)

Naïve Realists think that the ordinary mind-independent objects that we perceive are constitutive of the character of experience. Some understand this in terms of the idea that experience is diaphanous: that the conscious character of a perceptual experience is entirely constituted by its objects. My main goal here is to argue that Naïve Realists should reject this, but I’ll also highlight some suggestions as to how Naïve Realism might be developed in a non-diaphanous direction.

Some philosophers have argued recently that introspective evidence provides direct support for an intentionalist theory of visual experience. An intentionalist theory of visual experience treats experience as an intentional state, a state with an intentional content. (I shall use the word ’state’ in a general way, for any kind of mental phenomenon, and here I shall not distinguish states proper from events, though the distinction is important.) Intentionalist theories characteristically say that the phenomenal character of an experience, what it is (...) like to have the experience, is exhausted by its intentional content. Visual experience, and on some views sense-experience generally, does not involve the awareness of ’qualia’, intrinsic, non-intentional features of the experience. According to Gilbert Harman and Michael Tye, support for this view comes from introspecting on experience. Tye describes his ’argument from introspection’ as follows: Standing on the beach in Santa Barbara a couple of summers ago on a bright sunny day, I found myself transfixed by the intense blue of the Pacific Ocean. Was I not here delighting in the phenomenal aspects of my visual experience? And if I was, doesn’t this show that there are visual qualia? I am not convinced. It seems to me that what I found so pleasing in the above instance, what I was focusing on, as it were, were a certain shade and intensity of the colour blue. I experienced blue as a property of the ocean not as a property of my experience. My experience itself certainly wasn’t blue. Rather, it was an experience which represented the ocean as blue. What I was really delighting in, then, were specific aspects of the content of the experience. Tye goes on to suggest that this might have been the sort of thing Moore meant when he said that the sensation of blue is ’diaphanous’, and glosses this as follows: When one tries to focus on it in introspection one cannot help but see right through it so that what one actually ends up attending to is the real colour blue. 1An early version of this paper was presented at the conference, Mental Phenomena III in Dubrovnik, Croatia..

Many contemporary theorists charge that naïve realists are incapable of accounting for illusions. Various sophisticated proposals have been ventured to meet this charge. Here, we take a different approach and dispute whether the naïve realist owes any distinctive account of illusion. To this end, we begin with a simple, naïve account of veridical perception. We then examine the case that this account cannot be extended to illusions. By reconstructing an explicit version of this argument, we show that it depends critically (...) on the contention that perceptual experience is diaphanous, or more minimally and precisely, that there can be no difference in phenomenal properties between two experiences without a difference in the scenes presented in those experiences. Finding no good reason to accept this claim, we develop and defend a simple, naïve account of both veridical perception and illusion, here dubbed Simple, Austere Naïve Realism. (shrink)

G.E. Moore alludes to a notion of consciousness that is diaphanous, elusive to attention, yet detectable. Such a notion, I suggest, approximates what Bina Gupta has called `witness-consciousness'--in particular, the aspect of mode-neutral awareness with intrinsic phenomenal character. This paper offers a detailed definition and defence of the appearance and reality of witness-consciousness. While I claim that witness- consciousness captures the essence of subjectivity, and so must be accounted for in the `hard problem' of consciousness, it is not to be (...) confused with the more commonly defended notion of `for-me-ness'.

According to the transparency thesis, some conscious states are transparent or “diaphanous”. This thesis is often believed to be incompatible with an inner‐awareness account of phenomenal consciousness. In this article, I reject this incompatibility. Instead, I defend a compatibilist approach to transparency. To date, most attempts to do so require a rejection of strong transparency in favor of weak transparency. In this view, transparent states can be attended to by attending (in the right way) to the presented world: that is, (...) they are merely translucent. Here, I first argue that this understanding of transparency is too weak to qualify as a compatibilist view. Drawing on insights from Franz Brentano, I then describe a middle road between strong and weak transparency. The crucial idea is that, although transparent states cannot be attended to, they can be noticed (under suitable conditions). This view, I submit, allows supporters of inner awareness to commit themselves to a more interesting understanding of transparency—moderate transparency—that preserves the initial intuition underlying the transparency metaphor.

I propose that there are two kind's of qualia realism, and that Harman's observations about the transparency of experience pose a threat to only one of these.
