" The acknowledged American leader of the new science of anthropology, Boas was a scrupulous master of detail drawn from his field experience. Boas's The Mind of Primitive Man (1911; revised and enlarged in 1938) demonstrated that "there is no fundamental difference in the ways of thinking of primitive and civilized man." He attacked simplistic racial stereotypes and insisted that "A close connection between race and personality has never been established." His conclusions were firmly based on facts gathered in the field. Boas argued that all surviving societies show equally the capacity to develop culture. They have evolved equally but differently. So he diverted the social scientists' focus from biology (the realism of evolution) to anthropology. And he received the accolade of the German Nazis when they burned his books and rescinded his German Ph.D. "
