Forman links the emergence of quantum mechanics, and Bohr's Copenhagen interpretation in particular, to the postwar revolt against rationalist and causal-realist philosophies of science.
Forman (1971) argued the remarkable scientific achievements in quantum physics in Weimar Germany in the 1920s involved the cross-product of the hostile intellectual atmosphere whereby many scientists rejected Weimar Germany as an illegitimate state and in which there were intellectual revolts against causality, determinism and materialism.
