Non-Empiricist Naturalism
This chapter elucidates Wittgenstein’s later non-empiricist naturalism. This novel kind of naturalism makes it possible to recognize the relevance of natural historical considerations concerning humans and language use for logic, while retaining the traditional conception of logic as a non-empirical discipline. The justification and generality of the employment of natural history based logical models is explained, and distinguished from the justification and generality of empirical statements. The different ways in which Wittgenstein makes use of natural historical considerations in logical or grammatical clarification are discussed, and the difference of Wittgenstein’s approach from broadly Kantian philosophical anthropology clarified. The correctness or truth of logical accounts is explained and a method of multidimensional logical descriptions introduced.
