jew Franz Boaz

How do we know Boaz was a jew?:

"no truly pure race exists"

Only a jew would make that racist, ridiculous, STUPID claim?

"Boas organized and took part in the Jesup North Pacific expedition of 1902, which suggested the possibility of a strong relationship between northern Asian and northwestern American cultures. He was president of the American Anthropological Society (1907-8) and of the New York Academy of Sciences (1910). Boas's anthropological studies have become classics in the field. He pioneered in the use of a scientific approach to anthropology. He also demonstrated the necessity of studying a culture in all its aspects, including its religion, art, history, and language, as well as the physical characteristics of the people. One of his most important conclusions was that no truly pure race exists, and that no race is innately superior to any other. "

Franz Boas was born in Minden, Westphalia. Although his grandparents were observant Jews, his parents, like most German Jews, embraced Enlightenment values, including their assimilation into modern German society. Boas was sensitive about his Jewish background, and while he vocally opposed anti-Semitism and refused to convert to Christianity, he did not identify himself as a Jew; indeed, according to his biographer, "He was an 'ethnic' German, preserving and promoting German culture and values in America."^[5] In an autobiographical sketch, Boas wrote:

The background of my early thinking was a German home in which the ideals of the revolution of 1848 were a living force. My father, liberal, but not active in public affairs; my mother, idealistic, with a lively interest in public matters; the founder about 1854 of the kindergarten in my home town, devoted to science. My parents had broken through the shackles of dogma. My father had retained an emotional affection for the ceremonial of his parental home, without allowing it to influence his intellectual freedom.

From his early experience at the Froebel kindergarten in Minden, to his studies at Gymnasium, Boas was exposed to, and interested in, natural history. Of his work at Gymnasium, he was most excited by and proud of his research on the geographic distribution of plants. Nevertheless, when Boas attended university — first at Heidelberg, then Bonn, where he joined the fraternity Burschenschaft Alemannia zu Bonn, in which he stayed for his whole life, — he focused on mathematics and physics (although he also attended a few courses in geography, including one taught by Theobald Fischer). He intended then to study physics at Berlin, but chose to attend the university at Kiel, in order to be closer to his family. There he studied physics with Gustav Karsten. Boas wished to conduct research concerning Gauss's law of the normal distribution of errors, but Karsten instructed him to research the optical properties of water instead. That research became the basis of his doctoral dissertation.
