Ecumenical Noninferential Anti-skepticism

This chapter employs the intuitionist particularist approach laid out in Chapters Six and Seven to develop an ecumenical noninferential anti-skeptic’s response to the underdetermination arguments (considered earlier in the book) for radical skepticism about perception, memory, a priori intuition, introspection, and reasoning. The sense in which this response is ecumenical is that it can easily be endorsed by both internalists and externalists in epistemology. The chapter concludes by arguing that, despite the ecumenical nature of this anti-skeptical response to radical skepticism, one lesson of the book so far is that there is a sense in which “externalism” of a certain kind (acceptable to both internalists and externalists alike) wins the day.
