"Pride, ill nature, and want of sense are the three great sources of ill manners; without some one of these defects, no man will behave himself ill for want of experience, or what, in the language of fools, is called knowing the world."

For war to man, like childbirth to women, is simplifying in its emotions and activities. All the real problems of life can be put aside while the one thing is done and little thought is needed to do it. ... His hatreds can be expressed without censure, he can let his emotions run free, he can behave as dramatically, as heroically as he likes, and no one laughs at him. It is almost impossible for a man to behave heroically in the cool and ordinary times of peace. But in war anything is allowed him, he is praised and applauded and made much of, as women are excused and allowed for in pregnancy.
