What broke in a man when he could bring himself to kill another? What broke when he could bring himself to thrust down the knife into the warm flesh, to bring down the axe on the living head, to cleave down between the seeing eyes, to shoot the gun that would drive death into the beating heart?
The only way in which one can make endurable man's inhumanity to man, and man's destruction of his own environment, is to exemplify in your own lives man's humanity to man and man's reverence for the place in which he lives.
