Philosophical Skepticism and Externalist Epistemology

Show Summary Details


This chapter considers the following thesis and its supporting argument. Philosophical Skepticism: There is no way we could ever attain full philosophical understanding of our knowledge. The Radical Argument: (A1) Any theory of knowledge must be internalist or externalist. (A2) A fully general internalist theory is impossible. (A3) A fully general externalist theory is impossible. (C) Therefore, philosophical skepticism is true. It argues that there is no good reason to yield to the skeptic or to reject externalist theories of knowledge globally and antecedently as theories that could not possibly give us the kind of understanding of human knowledge in general that is a goal of epistemology. And so there is no good reason to accept philosophical skepticism, the main target thesis of this chapter.
