"Humanity today is not safe in the presence of humanity. The old cannibalism has given way to anonymous action in which the killer and the killed do not know each other, and in which,indeed, the very fact of mass death has the effect of making mass killing less reprehensible than the death of a single individual. In short, we have evolved in every respect except our ability to protect ourselves against human intelligence. Our knowledge is vast but does not embrace the workings of peace."
