‘On Being Debased’

Abstract A standard form of skeptical scenario, in the tradition of Descartes’ evil demon, raises the prospect that our sensory experiences are deceptive. A less familiar and importantly different kind of skeptical scenario raises the prospect that our beliefs have been debased (Schaffer, 2010). This paper provides a new and improved way of resisting this latter kind of debasing skepticism. Along the way, I explore how the debasing demon scenario connects with some potentially controversial epistemological principles and clear up various neglected or misunderstood points concerning debasing skepticism.
