Vienna Circle - History of The Vienna Circle

History of The Vienna Circle

The pre-history of the Vienna Circle began with meetings on the philosophy of science and epistemology from 1908 on, promoted by Philipp Frank, Hans Hahn and Otto Neurath.

Hans Hahn, the oldest of the three (1879–1934), was a mathematician. He received his degree in mathematics in 1902. Afterwards he studied under the direction of Ludwig Boltzmann in Vienna and David Hilbert, Felix Klein and Hermann Minkowski in Göttingen. In 1905 he received the Habilitation in mathematics. He taught at Innsbruck (1905–1906) and Vienna (from 1909).

Otto Neurath (1882–1945) studied sociology, economics and philosophy in Vienna and Berlin. From 1907 to 1914 he taught in Vienna at the Neuen Wiener Handelsakademie (Viennese Commercial Academy). Neurath married Olga, Hahn's sister, in 1911.

Philipp Frank, the youngest of the group (1884–1966), studied physics at Göttingen and Vienna with Ludwig Boltzmann, David Hilbert and Felix Klein. From 1912, he held the chair of theoretical physics in the German University in Prague.

Their meetings were held in Viennese coffeehouses from 1907 onward. Frank remembered:

After 1910 there began in Vienna a movement which regarded Mach's positivist philosophy of science as having great importance for general intellectual life An attempt was made by a group of young men to retain the most essential points of Mach's positivism, especially his stand against the misuse of metaphysics in science. To this group belonged the mathematician H. Hahn, the political economist Otto Neurath, and the author of this book, at the time an instructor in theoretical physics in Vienna. We tried to supplement Mach's ideas by those of the French philosophy of science of Henri Poincaré and Pierre Duhem, and also to connect them with the investigations in logic of such authors as Couturat, Schröder, Hilbert, etc.

Presumably the meetings stopped in 1912, when Frank went to Prague, to hold the chair of theoretical physics left vacant by Albert Einstein. Hahn left Vienna during World War I and returned in 1921. The following year Hahn, with the collaboration of Frank, arranged to bring into the group Moritz Schlick, who held the chair of philosophy of the inductive sciences at the University of Vienna. Schlick had already published his two main works Raum und Zeit in die gegenwärtigen Physik (Space and Time in contemporary Physics) in 1917 and Allgemeine Erkenntnislehre (General Theory of Knowledge) in 1918. A central work for the newly founded discussion group was the Logisch-Philosophische Abhandlung (Tractatus Logico-Philosophicus), published by Ludwig Wittgenstein in 1921 (in 1922 in German-English version).

Under the direction of Schlick, a new regular series of meetings began. In 1926 Schlick and Hahn arranged to bring in Rudolf Carnap at the University of Vienna. In 1928 the Verein Ernst Mach (Ernst Mach Society) was founded, with Schlick as chairman. In 1929 the Vienna Circle manifesto Wissenschaftliche Weltauffassung. Der Wiener Kreis (The Scientific Conception of the World. The Vienna Circle) was published. The pamphlet is dedicated to Schlick, and its preface was signed by Hahn, Neurath and Carnap. In the appendix is a list of the members of the Vienna Circle.

The Vienna Circle was dispersed when the Nazi party came to power in Germany; many of its members emigrated to USA, where they taught in several universities. Schlick remained in Austria, but in 1936 he was killed by a Nazi sympathizer student in the University of Vienna.

The Kraft Circle, a successor to the Vienna Circle, arose in 1949 under the leadership of Viktor Kraft. Its philosophical programme was continued long after its demise (1952/3) by Paul Feyerabend.
