This chapter examines the distinction between practical and propositional (or theoretical) knowledge. It then considers the objections put forward by Stanley and Williamson and finds them wanting. Afterwards, it presents Chomsky's position on linguistic competence as a form of propositional knowledge. It criticizes both the theoretical and the empirical arguments Chomsky puts forward in favor of his view and presents some observations in favor of the idea that linguistic competence is ultimately practical. In so doing, it aims to re-habilitate the picture of practical knowledge and of linguistic competence endorsed, arguably, by Wittgenstein and Ryle.
