 Consider analyticity. Here again, the traditional idea—sometimes defended by some members—did show itself indefensible, but this leaves Carnap’s framework-relative interpretation of analyticity and the understanding of the a priori as equally relative to be explored. As noted, if Carnap’s ramseyfications can be defended, an analytic/synthetic distinction could be upheld also for the theoretical languages of science. In any case, however, the distinction between framework principles and content continues to be drawable on a case by case basis.
