Carnap’s Logischer Aufbau der Welt (1928) shows in which direction future systematic work will move. Wittgenstein’s Tractatus Logico-Philosophicus (1921) clarified, among other things, the position of logic and mathematics; besides the statements that make additions to what is meaningful, there are the ‘tautologies’ that show us which transformations are possible within language. By its syntax the language of science excludes anything that is meaningless from the very beginning.

The motivationless theory of goods [transfers] can bridge the gulf between history and exact research by securing the important continuity of the research, being linked to both.

At first the Vienna Circle analysed ‘physics’ in a narrower sense almost exclusively; now psychology, biology,sociology. The task of this movement is unified science and nothing less.
