ViennaCircle

The Vienna Circle is a group of philosophers who gathered round Moritz Schlick, after his coming in Vienna in 1922. They organized a philosophical association, named Verein Ernst Mach (Ernst Mach Association). However, meetings on philosophy of science and epistemology began as early as 1907, promoted by Frank, Hahn and Neurath, who later arranged to bring Schlick at the University of Vienna. Among Vienna Circle’s members were M. Schlick, Rudolf Carnap, H. Feigl, P. Frank, K. Gödel, H. Hahn, V. Kraft, O. Neurath, F. Waismann. Also K. R. Popper and H. Kelsen had many contacts with the Vienna Circle, although they did not belong to it. At the meetings, the Tractatus of Ludwig Wittgenstein was also discussed, and there were several meetings between Wittgenstein, Schlick, Waismann and Carnap. In 1929 Hahn, Neurath and Carnap published the manifesto of the circle: Wissenschaftliche Weltauffassung. Der Wiener Kreis (A scientific world-view. The Vienna Circle).

Vienna Circle was very active in advertising the new philosophical ideas of logical positivism.
