What Phenomenal Consciousness is Like (
MIT - Massachusetts Institute of Technology)
This paper has the following three goals, in ascending order of ambition. First, to show that there is
a genuine dispute in the vicinity. Second, to rebut arguments against first-order theories based on a distinction (to be explained shortly) between “experiences” and “conscious experiences”. Third, to show that higher-order theories are mistaken. Even if none of these goals is met, at least the paper can serve as a terminological guide for the perplexed. ...
According to [First Order] theories, an event may be phenomenally conscious even though it is not represented by one of the subject’s mental states/events. In other words, higher-order representations are not
necessary for phenomenal consciousness. In particular, we may take the first-order theorist to hold that a certain first-order condition—to be explained in a moment—is
sufficient for having phenomenal character G. Take a phenomenally conscious perceptual experience e of a cucumber in daylight. If e is in fact represented by one of the subject’s mental states/events, then consider e*, an event as similar to e as possible, except that e* is not represented by one of the subject’s mental states/events. (Hence, if e is not in fact the target of a higher-order representation, then e*=e.) Repeat this process for other phenomenally conscious experiences of cucumbers, limes, green peppers,..., resulting in other (possible) experiences e**, e***,... Then the first-order theorist’s sufficient condition for G is this: being mentally exactly like e* (or like e**, or like e***,...).
According to [Higher Order] theories, on the other hand, higher-order representations
are necessary for phenomenal consciousness. On this view, e* is
not phenomenally conscious (and hence does not have G). That is, the higher-order theorist claims that there can be events that are mentally exactly like phenomenally conscious experiences, except that they are not targeted by higher-order representations, and thus are not phenomenally conscious. ...
According to the FOR theorist, necessarily any experience of green is (phenomenally) conscious; according to the HOR theorist, there could be experiences of green that are not conscious. Of course, the FOR theorist will add other sufficient conditions for phenomenal consciousness (in our abbreviated formulation: being an experience of blue, being an experience of triangularity, and so on); again, the HOR theorist will claim that there could be such experiences that are not conscious. ...
3. Experiences vs. conscious experiences: three accounts of this distinction
3.1 Carruthers: worldly vs. experiential subjectivity
Carruthers’ distinction between
worldly subjectivity (what the
world is like for the subject) and
experiential subjectivity (what the
subject’s experience is like for the subject) is one between properties:
...what the world (or state of the organism’s own body) is like for an organism...is a property of the world (or of a world-perceiver pair, perhaps). And:
...what the organism’s experience of the world (or of its own body) is like for the organism...is a property of the organism’s experience of the world (or of an experience-experience pair) (2000: 127-8)
