 Focusing on the question how war and violence can be overcome on a global scale, Duhm became intensively interested in the theories of the Marxist psychoanalyst Wilhelm Reich.His contention with and eventual renunciation of Reich led him into a deeper study of Asiatic traditions, such as different meditation practises, Yoga, T'ai chi, and others.As indicated by the titles of his published work, Duhm was never a purely Marxist economist, but had always been interested in the individual, psychological issues underlying the world’s problems.
