 and a 'picture theory' of language. Schlick and his group were overwhelmed by the work: they made it a topic for discussion at nearly every meeting. Schlick himself contacted Wittgenstein in 1924 and extolled the virtues of Wittgenstein's book vis-a-vis his immediate circle. Eventually Wittgenstein agreed to meet with Schlick and Waismann to discuss the Tractatus and other ideas. Through Schlick's influence, Wittgenstein was encouraged to consider a return to philosophy after some ten years of idleness. It is partly to Schlick's credit that Wittgenstein began to pen the reflections that make up large parts of Philosophical InvestigationsPhilosophical Investigations

. Schlick and Waismann's discussions with Wittgenstein continued until the latter felt that germinal ideas had been used without permission in an essay by Carnap. Wittgenstein continued discussions in letters to Schlick, but his formal association with the Vienna Circle ended in 1932.

Schlick had worked on his Allgemeine Erkenntnislehre (General Theory of Knowledge) between 1918 and 1925, and, though later developments in his philosophy were to make various contentions of his epistemology untenable, the General Theory is perhaps his greatest work in its acute reasoning against synthetic a priori knowledge. This critique of synthetic a priori knowledge argues that the only truths which are self-evident to reason are statements which are true as a matter of definition, such as the statements of formal logic and mathematics. The truth of all other statements must be evaluated with reference to empirical evidence. If a statement is proposed which is not a matter of definition, and not capable of being confirmed or falsified by evidence, that statement is "metaphysical", which is synonymous with "meaningless", or "nonsense". This is the principle upon which members of the Vienna Circle were most clearly in agreement. Between 1926 and 1930, Schlick labored to finish Fragen der Ethik (Problems of Ethics), in which he surprised some of his fellow Circlists by including ethics as a viable branch of philosophy. Also during this time, the Vienna Circle published The Scientific View of the World: The Vienna Circle as an homage to Schlick. Its strong anti-metaphysical stance crystallized the viewpoint of the group.

 in Germany and Austria, many of the Vienna Circle's members left for America and the United Kingdom. Schlick, however, stayed on at the University of Vienna. When visited by Herbert Feigl in 1935, he expressed dismay at events in Germany. On June 22, 1936, Schlick was ascending the steps of the University for a class when he was confronted by a former student, Johann NelböckJohann Nelböck

(That Schlick was not Jewish tended to be overlooked.) Nelböck was paroled shortly afterward and became a member of the Austrian Nazi Party after the AnschlussAnschluss

Legacy

Schlick's enduring contribution to the world of philosophy is as the fount of logical positivism. His humanity, good will, gentleness, and especially his encouragement have been documented by many of his peers. Herbert Feigl and Albert Blumberg, in their excellent introduction to "General Theory of Knowledge," have written,
