Kwan’s objection: One has various sensations in one’s sleep, e.g. when one is undergoing a vivid dream. One is unconscious when one is sleeping, so there are unconscious sensations, contrary to what Deutsch claimed.

Reply: ‘Conscious’ and ‘consciousness’ are notoriously ambiguous--they have more than one meaning.

There is (1) consciousness-as-awareness, (2) consciousness-as-having a phenomenology, and (3) consciousness-as-being awake.

So the following questions are also ambiguous:

(a) Can there be unconscious sensations?

(b) Can there be unconscious attitudes?

But the answer to (b) is ‘yes’ for interpretations (1)-(3), while the answer to (a) is ‘yes’ on interpretations (1) and (3), but ‘no’ on interpretation (2).
