Otto Neurath (December 10 1882-December 22 1945) was an Austrian sociologist, political economist and arguably one of the most unorthodox Marxists.
Member of the 'left wing' of the Vienna Circle, he rejected both metaphysics and epistemology. Neurath viewed Marxism as a type of science and he saw science as a tool for change. He also headed Bavaria's programme for socialization in 1919.
