War is an old, old plant on this earth, and a natural history of it would have to tell us under what soil conditions it grows, where it plays havoc, and how it is eliminated.
If we justify war, it is because all peoples always justify the traits of which they find themselves possessed, not because war will bear an objective examination of its merits
War is, we have been forced to admit, even in the face of its huge place in our civilization, an asocial trait.
... it is a commonplace that men like war. For peace, in our society, with the feeling we have then that it is feeble-minded to strive except for one's own private profit, is a lonely thing and a hazardous business. Over and over men have proved that they prefer the hazards of war with all its suffering. It has its compensations.
