 The claim that introspective access is both epistemically and metaphysically direct is most plausible for sensations like pain. This is because how a sensation appears—how it seems to the subject—and how it actually is (its nature) are, according to many philosophers, one and the same. That is, “there is no appearance/reality distinction in the case of sensations” (Hill 1991: 127; compare Kripke 1980: 152–3).
