Reason and Communication

Kant introduces the concept of 'communicability' in the 3rd Critique, primarily to explain Aesthetic Judgment.  However, it is clear from his exposition that it is not only aesthetic feeling that he regards as 'communicable'.  For example, at #40, he asserts that a "moral feeling , , , can be communicated universally , , , by means of reason."  What is significant in this passage is that it implies that Reason is not a content of communication, but is, itself, a medium of communication.  In other words, Kant is here evinced as conceiving Reason to be a specific linguistic pattern, rather than a pre-linguistic process that contingently gets verbally expressed.  The passage is, thus, evidence that Kant conceives Reason to be essentially linguistic, from which it follows that Cognition is essentially linguistic, and that Language is an a priori capacity, which Cassirer and Chomsky seem to appreciate better than many other neo-Kantians.
