But American nationalism has been conditioned, to a large extent, by the "indoctrination" of the children of immigrants, inevitably coupled with a certain denigration of the Old World. Any German, or Italian, or American gentleman will naturally defend his country against patently unjust accusations—loyalty demands this; but he will not try to convince others that his nation has the highest qualities in the world, the most gifted inventors, the most profound philosophers, the best writers, the finest painters, the fastest trains, the most beautiful women. (This uncouth boasting is reserved for the traveling salesman after a third drink, or the likes of a National Socialist or a Russian Communist.)
