 A.D. Smith claims that what most authors have in mind in talking about the Problem of Perception is the “question of whether we can ever directly perceive the physical world”, where “the physical world” is understood in a realist way: as having “an existence that is not in any way dependent upon its being... perceived or thought about” (2002: 1). The arguments at the heart of the Problem of Perception challenge this direct realist perspective on perceptual experience. But since this perspective is embedded within our ordinary conception of perceptual experience, the problem gets to the heart of our ordinary ways of thinking.
