A priori tautologies

On second thoughts, logically a priori statements are slightly interesting, because the rules that they ultimately depend on are only intelligible within practices which, themselves, are at least partly 'hinged' upon non-tautological a priori statements.

It is not possible to articulate a logic without a language to articulate the logic in, and the possibility of this language, if it is considered by its speakers, must be the subject of an a priori judgment.

The necessity of logical laws follows from the a priori possibility of the language in which they are entertained.
