Having, in previous papers, distinguished at least three forms of consciousness , I now further examine their differences. This examination has some surprising results. Having argued that neither C1 nor C2 is a phenomenological state?and so different from CN?I now show that CN itself is best thought of as a subclass of a larger state . CS is the set of image?representation states. CN is that set of CS states that we are also C2 about. I argue that CN states (...) should be considered a subset of CS states because they share with other CS states imagistic representational powers as opposed to the sentential ones of C1 and C2. And I argue that there are good reasons to consider any state which utilises imagistic representation as a sensation. I then show that the notion of an unconscious sensation makes sense if we think of it as a CS state that is not C2. More radically, I conclude that either it makes sense to say that there are unfelt sensations or there are felt sensations we are not conscious about. While there are good reasons for saying one or the other of these surprising things, I argue that the second, more radical sounding, alternative is actually better motivated?and not quite so surprising as it sounds.

Book synopsis: The philosophy of mind is one of the fastest-growing areas in philosophy, not least because of its connections with related areas of psychology, linguistics and computation. This Companion is an alphabetically arranged reference guide to the subject, firmly rooted in the philosophy of mind, but with a number of entries that survey adjacent fields of interest. The book is introduced by the editor's substantial Essay on the Philosophy of Mind which serves as an overview of the subject, and (...) is closely referenced to the entries in the Companion. Among the entries themselves are several ""self-profiles"" by leading philosophers in the field, including Chomsky, Davidson, Dennett, Dretske, Fodor, Lewis, Searle and Stalnaker, in which their own positions within the subject are articulated. In some more complex areas, more than one author has been invited to write on the same topic, giving a polarity of viewpoints within the book's overall coverage. (shrink)
