Abstract

Epistemology has changed dramatically since Descartes, but many of the questions epistemologists address today are no different from the questions Descartes addressed. I begin by raising four sets of questions with which Descartes concerned himself, and explain briefly why Descartes regarded these sets of questions as interchangeable. My main purpose, however, is not historical. Rather, I wish to present an outline of a naturalistic approach to these questions. I will not defend naturalistic epistemology. Instead, I hope to explore what a naturalistic approach to some traditional epistemological questions might look like; it is only through a better understanding of the consequences of naturalizing epistemology that we may hope properly to evaluate it. I will argue that questions which Descartes treated as interchangeable will have to be separated by naturalistically minded epistemologists. In the course of evaluating these questions from a naturalistic point of view, I hope to shed some light on the relation between reliability and justification, the dispute between internalist and externalist theories of justification, and the relation between ethics and epistemology.
