Book excerpt: In Nazi Germany between the years 1940 and 1944, proof of your Aryan or Semitic roots meant the difference between life and death. How this inhuman and intrinsically absurd theory of racial superiority originated and how it took hold of the German imagination makes for a fascinating, scholarly study. Tracing the origins of the Aryan Myth in the West, the author shows how in the heyday of nationalism, most European people developed legends glorifying their high born ancestry. He shows how these legends developed into pseudoscientific theories, which treated Europeans as the norm and other peoples as inferior--until in 19th-century Germany they culminated in the concept of a superior Germanic "race" in contrast to the inferior Jewish "race." This cultural study sheds horrifying new light on the philosophy that "justified" the mass extermination of millions of "subhumans" during World War II.--From publisher description.
