We are a race of doers and fighters, of globe-encirclers and zone-conquerors …. While we are persistent and resistant, we are made so that we fit ourselves to the most diverse conditions. Will the Indian, the Negro, or the Mongol ever conquer the Teuton? Surely not! The Indian has persistence without variability; if he does not modify he dies, if he does try to modify he dies anyway. The Negro has adaptability, but he is servile and must be led. As for the Chinese, they are permanent. All that the other races are not, the Anglo-Saxon, or Teuton if you please, is. All that the other races have not, the Teuton has.
