This paper contrasts two varieties of naturalism: realistic naturalism and pragmatic naturalism. These two views both reject a priori knowledge, but then they differ in many ways. For realistic naturalists, meaning and knowledge are to be understood in terms of causal relations. By contrast, pragmatists think that meaning and knowledge can be understood only in relation to normatively constructed practices.
