Abstract

In this paper I will be setting aside contextualists and closure-deniers and focusing solely on neo-Moorean versions of externalist responses to skepticism. I will be focusing on two prominent theses about externalist responses to skepticism, one positive and one negative. The positive thesis announces an alleged virtue of externalism: that externalism alone avoids skepticism. The negative thesis identifies an alleged defect of externalism: that externalism implausibly avoids skepticism. I will be critical of both theses, though I will try to uncover the truth in the neighborhood of each. I’ll close by arguing briefly that the conclusions reached in examining these two theses give us a reason to endorse externalism.
