Lycan’s suggestion that olfactory experiences are apparent as modifications of one’s own consciousness depends heavily on the aspatial phenomenology of olfactory experience (Lycan 2000, 278–82). Each recalls the Kantian claim that objectivity requires space, or that grasping something as independent from oneself requires the experience of space, a version of which is deployed by Strawson (1959, ch 2) in his famous discussion of sounds.
