"It is the height of folly to assume that environment, discipline, education, and all other external devices can affect the blood, smooth down inequalities between individuals of the same breed, much less between different breeds, or transmute racial qualities... The Germans appreciate the importance of race values. They understand that racial improvement is the greatest asset that any country can have...They know, as few other nations have realized, that the impoverishment of race values contributes more to the impairment and destruction of a civilization than any other agency.”"
