Kraft studied philosophy, geography and history at the University of Vienna. He participated in the events of the University’s Philosophical Society, as well as with private circles (especially Oskar Ewald, Otto Weininger and Othmar Spann). He received in 1903 his Ph.D. with a dissertation on "The Knowledge of the External World". Then he moved to Berlin to continue his studies under Georg Simmel, Wilhelm Dilthey and Carl Stumpf. Kraft started working in 1912 at the University’s library, where he was a scientific civil servant ("Beamter") until 1939. In 1914 he completed his habilitation under Adolf Stöhr with his book "Weltbegriff und Erkenntnisbegriff" (The Concept of world and the Concept of Knowledge). Kraft attend regularly the Vienna Circle until its dissolution, and at the same time was also a member of the Gomperz Circle and had contacts to the so-called periphery of the Vienna Circle (e.g., Karl Popper). Victor Kraft received the title of associate professor for theoretical philosophy in 1924.
After the Anschluss Kraft was forced to leave his librarian position because of his wife's Jewish background. He lost his habilitation as university teacher as well. Kraft continued his philosophical research with great difficulties as "inner emigrant" during the Nazi regime.
He regained his post at the university library in 1945, and became Generalstaatsbibliothekar (national librarian) in 1947. In this year he was also appointed associate professor for philosophy. Three years later he became full professor and co-director of the school of philosophy. He retired from his post in 1952. Kraft kept his research and publishing until his death. The Kraft Circle, which he chaired between 1949 and 1952/3, was named after him, and it was during this period that he supervised the dissertation of Paul Feyerabend.
Among the logical positivists, Kraft represent a unique standing point: he wrote about a non sensualist empiricism with a hypothetical-deductive structure. Before the First World War (and after it together with the Vienna Circle members) he dedicated most of his lectures and publications to promote scientific philosophy. He also made an important contributions to the establishment of ethics as science and wrote about the theory of geography and the philosophy of history.
