Otto Neurath an Organization Committee of the International Congresses for the Unity of Science, 3. Jänner 1935 Jänner 1935

A temporary committee was formed in Prague, September 7, 1934, charged with the task of organizing periodical international congresses for the Unity of Science. The aim of these congresses is to make known and to further the logistic investigations of Bertrand Russell, the studies represented by the Contributions to ERKENNTNIS, the writings of the “Wiener Kreis”, the metamathematical approach of David Hilbert, the metalogic of the Polish school, the scientific empiricism of American thinkers, and all movements of a similar temper. The topics of the various congresses will be determined from time to time. Since a main task is to present the essential nature of the scientific venture and habit of mind (“the logic of science”, “the logical syntax of the language of science”, “the unity of science”, “scientific empiricism” and the like), the first congress, which is to meet in Paris, is to be dedicated to the Philosophy of Science.

It would be an honor to have your cooperation, and the temporary committee invites you to become a member of the Permanent Committee. The statures and the procedure of this Committee will be determined at the
