Epistemological Disjunctivism and Anti-luminosity Arguments.

Epistemological disjunctivists hold that perceiving subjects have "reflective access" to factive perceptual support for belief. However, little has been done to elaborate the intended notion of reflection, or introspective awareness more generally. Moreover, critics have pointed out that the disjunctivist conception of "reflective access" can seem vulnerable to varieties of Williamson's anti-luminosity argument. In this paper I defend disjunctivism from this charge, arguing that it holds the resources for a potent defense of the claim that knowledge of perceptual states is luminous. Indeed, I argue that appreciating the relation between disjunctivism and luminosity sheds critical light on how the disjunctivist conceives of perceptual support for belief. [ABSTRACT FROM AUTHOR]
