Abstract
Epistemological naturalism has often been taken to be inimical to a priori knowledge, armchair knowledge, and epistemic normativity. This chapter argues that the relationship between epistemological naturalism and these other commitments is in fact considerably subtler than it is widely assumed to be. The chapter begins with a brief classificatory sketch of different kinds of naturalism, then focuses on forms of naturalism that have been especially significant in epistemology. Finally, one form of epistemological naturalism (labeled “lightweight epistemological naturalism”) is singled out for further examination, and found to be consistent with robust (nondeflated, noninstrumental) epistemic normativity, consistent with a priori knowledge, and noncommittal with respect to the prospects of negative experimental philosophy's critique of armchair knowledge.
