By the mid-1940s, Knight and Simons's research had undergone unprecedented divergence, and not just because they were now located in separate departments. Knight, according to Simons, was “increasingly preoccupied with philosophy and philosophies, not to mention historians, theologians, and anthropologists, et al., and is not deeply interested in concrete problems of economic policy.” Partly because of the divarication that now characterized their intellectual relationship, their personal relationship by early 1946 had grown distant and impersonal.
