Abstract (eng)
This master thesis considers the mathematician and philosopher Friedrich Waismann (1896-1959). He was a significant member of the Vienna Circle, a group whose members advocated Logical Empirism at the beginning of the twentieth century. On the one hand, the thesis takes up Waismann as a historical figure, and on the other, it discusses some of his philosophical positions. The historical study begins with Waismann’s time as a student in 1917 and extends through his emigration fleeing from National Socialism to his death in exile in England. The section “Dokumentation: Waismanns Wiener Zeit” depicts for the first time Waismann’s years as a student from 1917 to 1922. This is supplemented by a table of his teaching activities at the Wiener Volkshochschulen. During the 1920s and 1930s, Waismann became a conversation partner of Ludwig Wittgenstein (1889-1951), whose Tractatus logico-philosophicus he described in the context of another book. Waismann increasingly became an interpreter of Wittgenstein’s work until differences abruptly ended their collaboration in 1936. The thesis uses Friedrich Waismann’s Einführung in das mathematische Denken (1936) to examine Wittgenstein’s influence on Waismann, on the other hand, connections are made to earlier and later thoughts of both thinkers.
