In this paper I discuss Kant’s philosophy of grammar in order to argue that: (a) the formal analysis of language implies that there is a structural correspondence between logical and grammatical form; (b) there is a distinction between the sense in which logic is formal and the sense in which grammar is formal; (c) universal grammar descends from the system of categorial functions that are investigated in the transcendental analytic; (d) transcendental grammar implies that the universal form of human language (...) has its ground in the universal structure of thought; (e) the concept of a grammatical norm is clarified once we combine the theory of universal grammar with how linguistic experience takes place.
