Skepticism is both a historical and foundational problem in epistemology. Jonathan Schaffer (2010) has provided a new expression of its threat. The Debasing Demon appears to generate a novel form of radical doubt, one that has gained prominence in recent debates. Instead of targeting the connection between belief and truth, it undercuts the link between belief and evidence (or reasons). This contribution presents the Debasing Demon Problem, analyzing its reach. It will provide an account for explaining how its threat is (...) raised, explore its relationship to classical varieties of skepticism, and assess some of the main objections against it. It will be argued that Schaffer’s Demon institutes a consistent epistemic threat, one that might represent the main variety of skepticism to be tackled in epistemology. Some consequences of this analysis are then presented concerning how to face this open problem. (shrink)
