Dretske has recently offered a representational theory of perceptual experience - considered as paradigmatic of the qualitative and phenomenal aspects of our mental life. This theory belongs, as do his previous works, to a naturalistic approach to mental representation.

When philosophers and psychologists think about consciousness, they generally focus on one or more of three features: phenomenality , intentionality , and introspectibility . Using examples from empirical psychology and neuroscience, I argue that consciousness is not a unitary state, that, instead, these three features characterize different and dissociable states, which often happen to occur together. Understanding these three features as dissociable from each other will resolve philosophical disputes and facilitate scientific investigation.

This paper replies to the first 36 commentaries on my target article on “Is human information processing conscious?” (Behavioral and Brain Sciences,1991, pp.651-669). The target article focused largely on experimental studies of how consciousness relates to human information processing, tracing their relation from input through to output, while discussion of the implications of the findings both for cognitive psychology and philosophy of mind was relatively brief. The commentaries reversed this emphasis, and so, correspondingly, did the reply. The sequence of topics (...) in the reply roughly follows that of the target article. The discussion begins with a reconsideration of the details of the empirical findings, whether they can be extrapolated to non-laboratory settings, and the extent to which one can rely on their use of subjective reports. This is followed by an in-depth discussion of what is meant by “conscious processing” and of how phenomenal consciousness relates to attentional processing. We then turn to broader philosophical and theoretical issues. I point out some of the reasons why I do not support epiphenomenalism, dualist-interactionism, or reductionism, and elaborate on how first- and third-person views of the mind can be regarded as complementary and mutually irreducible. I suggest how the relation of conscious experiences to their neural correlates can be understood in terms of a dual-aspect theory of information,and how this might be used to resolve some of the paradoxes surrounding the causal interactions of consciousness and brain. I also suggest that, viewed from a first-person perspective, consciousness gives purpose to existence, which allows a different way of viewing its role in evolution. (shrink)

The cognitive mind-brain is haunted by the ghost of consciousness. Cognitive science must face this ghost, since consciousness is perhaps the most important mental phenomenon: it forms a seemingly united, multimodal phenomenological world around the subject who experiences this world from a certain point of view. Many current approaches to consciousness fail to illuminate the nature of this “experienced world”. Some philosophers want to eliminate consciousness from science for good, others build theories in which the concept of consciousness is distorted (...) beyond recognition. I argue that elimination and Daniel Dennett's “multiple drafts” model do not offer genuine explanations for consciousness. However, certain empirically-based approaches to consciousness succeed in exorcising its ghostly reputation and, at the same time, in preserving the experienced world of consciousness as an important explanandum.

In the visual system, the represented features of individual objects (shape, colour, movement, and so on) are distributed both in space and time within the brain. Representations of inner and outer event sequences arrive through different sense organs at different times, and are likewise distributed. Objects are nevertheless perceived as integrated wholes - and event sequences are experienced to form a coherent "consciousness stream." In their thoughtful article, Dennett & Kinsbourne ask how this is achieved.
