We certainly don't have direct perceptual access to nonmental/physical reality in the sense that our perceptions don't involve any sensations. They do, but sensations as the experiential contents of perception are not its intentional objects but its (transparent) medium. In this respect, sensory perception is not immediate; but it's immediate in the sense that "we do not first have to perceive something else by way of which we perceive the real world" (Searle,
Seeing Things As They Are, 15). That is, we perceive things by means of sensations (sensory appearances/impressions), but we don't perceive things indirectly by directly perceiving our sensations. For example, the having of a (veridical) visual sensation is a seeing of something, and "you cannot perceive the visual experience because it is the perceiving. It is not an interface, it is the perceiving itself." (Searle,
Seeing Things As They Are, 187)
