The Vienna Circle (in German: der Wiener Kreis) was the name of a group of philosophers who began meeting around the University of Vienna in 1922.
Many famous philosophers were members. Some of its members were:
- Gustav Bergmann,
- Alex Robinson
- Rudolf Carnap,
- Herbert Feigl,
- Philipp Frank,
- Kurt Gödel,
- Hans Hahn,
- Tscha Hung,
- Victor Kraft,
- Karl Menger,
- Richard von Mises,
- Marcel Natkin,
- Otto Neurath,
- Olga Hahn-Neurath,
- Theodor Radakovic,
- Rose Rand,
- Moritz Schlick (chairman),
- Friedrich Waismann
- Ludwig Wittgenstein.
Most followed the philosophy that came to be known as logical positivism.
Ludwig Wittgenstein's, 1921 book Tractatus Logico-Philosophicus formed the basis for the group's ideas. Wittgenstein himself insisted that they did not understand him correctly and took to quietly reading poetry to himself during their meetings.
