ABSTRACT
The philosophical movement of naturalism is normally divided into two strands. One is a methodological one: roughly, that philosophy (or some area of philosophy) should proceed using the methods of the sciences, particularly the natural sciences. The other is a metaphysical one: roughly, that the theory of the world that results from our philosophical inquiries should match, or at least not conflict with, what the sciences tell us there is. This chapter focuses on the first strand of naturalism. What does investigation of metaethics and ethics look like if we take a naturalist approach?
