Does the phenomenality of perceptual experience present an obstacle to phenomenal externalism?

Although Externalism is widely accepted as a thesis about belief, as a thesis about experience it is both controversial and unpopular. One potential explanation of this difference involves the phenomenality of perceptual experience-perhaps there is something about how perceptual experiences seem that straightforwardly speaks against Externalist accounts of their individuation conditions. In this paper, I investigate this idea by exploring the role that the phenomenality of color experience plays in a prominent argument against Phenomenal Externalism: Ned Block’s Inverted Earth Argument. In the course of carrying out this investigation, I will show that challenging Phenomenal Externalism on phenomenological grounds is not as straightforward a task as it is commonly assumed to be.
