 Whether the verificationist agenda was pursued in a formalist or pragmatic vein, however, all members shared the belief that meaningful statements divided exclusively into analytic and synthetic statements which, when asserted, were strictly matched with a priori and a posteriori reasoning for their support. The Vienna Circle wielded this pairing of epistemic and semantic notions as a weapon not only against the substantive a priori of the Schoolmen but also against Kant’s synthetic a priori. Moreover, their notion of analyticity comprized both logical and mathematical truths, thereby extending Wittgenstein’s understanding of the former as “tautological” in support of a broadly logicist program.
