Career
He and Else emigrated to Palestine in 1920, and founded, together with Martin Buber, the movement Brit Shalom which promoted a "dual-national" area where Jews and Arabs could live under equal conditions. He translated several of Rudolf Steiner"s books about Threefold Social Order to Hebrew. He became a Professor at the Hebrew University of Jerusalem, and later on the dean of the university.
He wrote on the nature of quantum mechanics and causality where he interpreted spontaneity in nature with the psychological idea that the closer we come to elements in nature or components in the individual, the less tenable is strict causal determinism and the more freedom we must grant to decisive personal elements.
"In corresponding areas of physics, the statistical law of averages takes on the same functions in determining temporal position and in prediction and reconstruction that the strict law of causality previously covered, but with the distinction that the individual case could be temporally located and predicted or reconstructed before, whereas now we deal only with the average." (1929) Hugo Bergmann"s name is used in The Postcard Killers as Dessie"s date in chapters 26 and 27.
