Taketani Mitsuo (武谷三男, October 2, 1911 - April 22, 2000) was a prominent Japanese physicist and Marxist. He published his Doctrine of the Three Stages of Scientific Development in 1936. This was the first Japanese contribution to the philosophy of science. He applied Hegel's theory of dialectics, with the triad Phenomenon, Substance, and Essence.
