Another early view in scientific racism was the polygenist view, which held that the different races had been separately created. Polygenist Christoph Meiners for example, split mankind into two divisions which he labeled the "beautiful White race" and the "ugly Black race". In Meiners' book, The Outline of History of Mankind, he claimed that a main characteristic of race is either beauty or ugliness. He viewed only the white race as beautiful. He considered ugly races to be inferior, immoral and animal-like. Anders Retzius demonstrated that neither Europeans nor others are one "pure race", but of mixed origins. While discredited, derivations of Blumenbach's taxonomy are still widely used for the classification of the population in the United States. Hans Peder Steensby, while strongly emphasizing that all humans today are of mixed origins, in 1907 claimed that the origins of human differences must be traced extraordinarily far back in time, and conjectured that the "purest race" today would be the Australian Aboriginals. Scientific racism fell strongly out of favor in the early 20th century, but the origins of fundamental human and societal differences are still researched within academia, in fields such as human genetics including paleogenetics, social anthropology, comparative politics, history of religions, history of ideas, prehistory, history, ethics, and psychiatry. There is widespread rejection of any methodology based on anything similar to Blumenbach's races. It is more unclear to which extent and when ethnic and national stereotypes are accepted. Although after World War II and the Holocaust, racist ideologies were discredited on ethical, political and scientific grounds, racism and racial discrimination have remained widespread around the world. Du Bois observed that it is not so much "race" that we think about, but culture: "... a common history, common laws and religion, similar habits of thought and a conscious striving together for certain ideals of life". Late 19th century nationalists were the first to embrace contemporary discourses on "race", ethnicity, and "survival of the fittest" to shape new nationalist doctrines. Ultimately, race came to represent not only the most important traits of the human body, but was also regarded as decisively shaping the character and personality of the nation. According to this view, culture is the physical manifestation created by ethnic groupings, as such fully determined by racial characteristics. Culture and race became considered intertwined and dependent upon each other, sometimes even to the extent of including nationality or language to
