Skepticism, Mental Disorder and Rationality

Abstract I stipulate and motivate the overlooked problem of demarcating radical skeptics (perceptual moral) from mentally disordered persons, given that both deny they know ordinary Moorean propositions (e.g., have hands or killing for fun is morally wrong). Call this ‘the demarcation problem’. In response to problem, develop a novel way demarcate between persons in an extensionally adequate saves appearance are not (at least typically). Finally, examine how Moorean, non-skeptical epistemologist would compare with terms what Plantinga calls internal external rationality. Perhaps surprisingly, by lights, fare better than skeptic (internal) The upshot Mooreans skeptical philosophy more epistemic evil mental disorder.
