“To say that war is madness is like saying that sex is madness: true enough, from the standpoint of a stateless eunuch, but merely a provocative epigram for those who must make their arrangements in the world as given.”

Light (1919), Ch. XVI - De Profundis Clamavi
Context: All is madness. And there is no one who will dare to rise and say that all is not madness, and that the future does not so appear — as fatal and unchangeable as a memory.
But how many men will there be who will dare, in face of the universal deluge which will be at the end as it was in the beginning, to get up and cry "No!" who will pronounce the terrible and irrefutable issue: —
"No! The interests of the people and the interests of all their present overlords are not the same.

1960s, The Quest for Peace and Justice (1964)
Context: We will not build a peaceful world by following a negative path. It is not enough to say "We must not wage war." It is necessary to love peace and sacrifice for it. We must concentrate not merely on the negative expulsion of war, but on the positive affirmation of peace. There is a fascinating little story that is preserved for us in Greek literature about Ulysses and the Sirens. The Sirens had the ability to sing so sweetly that sailors could not resist steering toward their island. Many ships were lured upon the rocks, and men forgot home, duty, and honor as they flung themselves into the sea to be embraced by arms that drew them down to death. Ulysses, determined not to be lured by the Sirens, first decided to tie himself tightly to the mast of his boat, and his crew stuffed their ears with wax. But finally he and his crew learned a better way to save themselves: they took on board the beautiful singer Orpheus whose melodies were sweeter than the music of the Sirens. When Orpheus sang, who bothered to listen to the Sirens? So we must fix our vision not merely on the negative expulsion of war, but upon the positive affirmation of peace. We must see that peace represents a sweeter music, a cosmic melody that is far superior to the discords of war.

On the Road (1957)
Context: They danced down the streets like dingledodies, and I shambled after as I've been doing all my life after people who interest me, because the only people for me are the mad ones, the ones who are mad to live, mad to talk, mad to be saved, desirous of everything at the same time, the ones who never yawn or say a commonplace thing, but burn, burn, burn like fabulous yellow roman candles exploding like spiders across the stars and in the middle you see the blue centerlight pop and everybody goes "Awww!"
