Suppose someone hears a loud noise and at the same time sees a yellow flash. It seems hard to deny that the person can experience
loudness and yellowness together. However, since loudness is experienced by the auditory sense whereas yellowness is experienced
by the visual sense it also seems hard to explain how – given the difference between the senses – loudness and yellowness
could possibly be experienced together. What is the solution to this problem? I start with some short remarks about what is
not the problem (Section 2) and continue to argue that, given one sense of “experiencing two qualities together”, there is
no philosophical problem at all (Section 3). An objection against this (Section 4) says that all this only concerns one kind
of consciousness, “access consciousness”, while what is relevant here is a different kind of consciousness, namely “phenomenal
consciousness”. I answer this objection by presenting another aspect of the unity of consciousness (Section 5). This case
raises puzzling further questions (Section 6) but it can help to answer the objection presented in Section 4. I will end with
some brief general speculation in a Kantian spirit (Section 7). The main upshot of this paper is a deflationary one: Where
we thought to be confronted with a serious philosophical problem there really is none. What will emerge through the argument
is a graded and functional view of the unity of consciousness.
