Wittgenstein, Russel, Carnap, Neurath, Schlick, G?del, Kant...
Yuck. All logical positivists and logical atomists. Wittgenstein, Godel, and Kant are the only non-positivists in that list. The early Wittgenstein was more of a mystic than a positivist (he thought the Vienna Circle had misunderstood him and had misread the Tractatus), and the later Wittgenstein was a pragmatist and postmodernist. Godel was part of the Vienna Circle (as far as I know). But he was a logical platonist (I added logical because his platonism stemmed from his theorems), not a logical empiricist. So he was not a true positivist. Positivism was unable to understand subjectivity. Also it had a outmoded epistemology. And the verification principle defeated itself. Besides that, the analytic-synthetic distinction was fundamentally wrong headed. But,the Circle's contributions to logic and mathematics is beyond debate. And their influence on modern philosophy is undeniable.
