"If a man were truly brave he wouldn't have to be always proving it to himself. So therefore I am forced to consider bravery suspect, and ridiculous, and dangerous. Because if there are enough young men like that who feel strongly enough about it, they can almost bring on a war, even when none of them want it, and are in fact struggling against having one. (And as far as modern war is concerned I am a pacifist. Hell, it isn't even war anymore, as far as that goes. It's an industry, a big business complex)."
