"The beliefs appropriate to the impulse of aggression may be seen in Bernhardi, or in the early Mohammedan conquerors, or, in full perfection, in the Book of Joshua. There is first of all a conviction of the superior excellence of one's own group, a certainty that they are in some sense the chosen people. This justifies the feeling that only the good and evil of one's own group is of real importance, and that the rest of the world is to be regarded merely as material for the triumph or salvation of the higher race. In modern politics this attitude is embodied in imperialism."
