This essay explains a Pyrrhonian skepticism in contrast with Cartesian skepticism, and then argues that what externalists and contextualists oppose is only Cartesian skepticism. It contends that externalists and contextualists actually back themselves into a Pyrrhonist position because externalists give up the search for reasons for belief, and contextualists admit that believers have no reasons for their beliefs within epistemological contexts, which is whenever skepticism is at issue.
