"This is a marvelous book, full of subtle, thoughtful, and original argument.

Charles Siewert's _The Significance of Consciousness_ contends that most philosophers and psychologists who have written about "consciousness" have neglected a crucial type or aspect that Siewert calls "phenomenal consciousness" and tries carefully to define. The present article argues that some philosophers, at least, have not neglected phenomenal consciousness and have offered tenable theories of it.

In _The Significance of Consciousness_ , Charles Siewert proposes a novel understanding of consciousness by arguing against higher-order views of consciousness and rejecting the traditional taxonomy of the mental into qualitative and intentional aspects. I discuss two puzzles that arise from these changes: first, how to account for first-person knowledge of our conscious states while denying that these are typically accompanied by higher-order states directed towards them; second, how to understand his claim that phenomenal features are intentional features without either (...) risking consciousness neglect or retreating to a more traditional understanding of the relation between qualitative and intentional character.

This commentary elaborates on Gray's conclusion that his neurophysiological model of consciousness might explain how consciousness arises from the brain, but does not address how consciousness evolved, affects behaviour or confers survival value. The commentary argues that such limitations apply to all neurophysiological or other third-person perspective models. To approach such questions the first-person nature of consciousness needs to be taken seriously in combination with third-person models of the brain.

Siewert identifies a special kind of conscious experience, phenomenal consciousness, that is the sort of consciousness missing in a variety of cases of blindsight. He then argues that phenomenal consciousness has been neglected by students of consciousness when it should not be. According to Siewert, the neglect is based at least in part on two false assumptions: (i) phenomenal features are not intentional and (ii) phenomenal character is restricted to sensory experience. By identifying an essential tension in Siewert's characterization of (...) phenomenal consciousness, I argue that his case for denying (i) and (ii) is at best incomplete. (shrink)
