In this paper I present a transcendental argument based on the findings of cognitive psychology and neurophysiology which invites two conclusions: First and foremost, that a pre-condition of visual perception itself is precisely what the Aristotelian and other commonsense realists maintain, namely, the independent existence of a featured, or pre-packaged world; second, this finding, combined with other reflections, suggests that, contra McDowell and other neo-Kantians, human beings have access to “things as they are in the world” via non-projective perception. These two conclusions taken together form the basis of “Aristotelian” metaphysical realism and a refutation of the neo-Kantian “two-factor” approach to perception.
