 It would appear then that despite continued resistance to recent revisionist scholarship—a resistance that consists not so much in contesting but in ignoring its results—the fortune of Vienna Circle philosophy has turned again. Restored from the numerous distortions of its teachings that accrued over generations of acolytes and opponents, the Vienna Circle is being recognized again as a force of considerable philosophical sophistication. Not only is it the case that its members profoundly influenced the actual development of analytical philosophy of science with conceptual initiatives that, typically, were seen through to their bitter end. It is also the case that some of its members offered proposals and suggested approaches that were not taken up widely at the time (if at all), but that are relevant again today. Much like its precursors Frege, Russell and Wittgenstein, the conventionalists Poincaré and Duhem, the pragmatists Peirce and Dewey—and like its contemporaries from Reichenbach’s Berlin Group and the Warsaw-Lvov school of logic to the Neo-Kantian Cassirer—the Vienna Circle affords a valuable vantage point on contemporary philosophy of empirical and formal science.
