Drawing on the findings of neuroscience, this text proposes and defends the hypothesis that the various modalities of sensation share a generic form that the author, Austen Clark, calls feature-placing.

Traditionally, perceptual experiences—for example, the experience of seeing a cat—were thought to have two quite distinct components. When one sees a cat, one’s experience is “about” the cat: this is the representational or intentional component of the experience. One’s experience also has phenomenal character: this is the sensational component of the experience. Although the intentional and sensational components at least typically go together, in principle they might come apart: the intentional component could be present without the sensational component or vice (...) versa.

Should a principle of charity be applied to the interpretation of the colour concepts exercised in visual experience? We think not. We shall argue, for one thing, that the grounds for applying a principle of charity are lacking in the case of colour concepts. More importantly, we shall argue that attempts at giving the experience of colour a charitable interpretation either fail to respect obvious features of that experience or fail to interpret it charitably, after all. Charity to visual experience (...) is therefore no motive for resisting the natural, Galilean response to a scientific understanding of light and vision. The best interpretation of colour experience ends up convicting it of widespread and systematic error. (shrink)

Animate vision systems have gaze control mechanisms that can actively position the camera coordinate system in response to physical stimuli. Compared to passive systems, animate systems show that visual computation can be vastly less expensive when considered in the larger context of behavior. The most important visual behavior is the ability to control the direction of gaze. This allows the use of very low resolution imaging that has a high virtual resolution. Using such a system in a controlled way provides (...) additional constraints that dramatically simplify the computations of early vision. Another important behavior is the way the environment “behaves‘. Animate systems under real-time constraints can further reduce their computational burden by using environmental cues that are perspicuous in the local context. A third source of economy is introduced when behaviors are learned. Because errors are rarely fatal, systems using learning algorithms can amortize computational cost over extended periods. Further economies can be achieved when the learning system uses indexical reference, which is a form of dynamic variable binding. Animate vision is a natural way of implementing this dynamic binding.

In 1995, in my book, Ten Problems of Consciousness, I proposed a version of the theory of phenomenal consciousness now known as representationalism. The present book, in part, consists of a further development of that theory along with replies to common objections. It is also concerned with two prominent challenges for any reductive theory of consciousness: the explanatory gap and the knowledge argument. In addition, it connects representationalism with two more general issues: the nature of color and the location of (...) the phylogenetic dividing line between those creatures that are phenomenally conscious and those that are not.

Gilbert Harman (1990) seeks to defend psychophysical functionalism by articulating a representationalist view of the qualities of experience. The negative side of the present paper argues that the resources of this representationalist view are insufficient to ground the evident distinction between perception and (mere) thought. This failure makes the view unable to support the uses to which Harman wishes to put it. Several rescuing moves by other representationalists are considered, but none is found successful. Part of the difficulty in Harman's (...) (...) work is that he does not adequately specify the view he rejects. The positive aim of the present paper is to provide a robust intrinsic quality account of experience that offers advantages in comparison with Harman's view, and that plainly does not fall to any of the arguments he advances.

Intuitions about the transparency of experience have recently begun to play a key role in the debate about qualia. Specifically, such intuitions have been used by representationalists to support their view that the phenomenal character of our experience can be wholly explained in terms of its intentional content.[i] But what exactly does it mean to say that experience is transparent? In my view, recent discussions of transparency leave matters considerably murkier than one would like. As I will suggest, there is (...) reason to believe that experience is not transparent in the way that representationalism requires. Although there is a sense in which experience can be said to be transparent, transparency in this sense does not give us any particular motivation for representationalism—or at least, not the pure or strong representationalism that it is usually invoked to support.

Representationalism is the position that the phenomenal character of a perceptual experience supervenes upon its representational content. The phenomenon of blurry vision is thought to raise a difficulty for this position. More specifically, it is alleged that representationalists cannot account for the phenomenal difference between clearly seeing an indistinct edge and blurrily seeing a distinct edge solely in terms of represented features of the surrounding environment. I defend representationalism from this objection by offering a novel account of the phenomenal difference (...) between these two kinds of cases. (shrink)
