“The most powerful single force in the world today is neither Communism nor Capitalism, neither the H-bomb nor the guided missile -- it is man's eternal desire to be free and independent.”

Oui interview (1979)
Context: The lifestyle that I have is probably neither desirable nor useful to most people. Most people are probably better off getting the certification they desire and spindling their lives away the way they’re doing. I don’t think they’d enjoy living any other way. There are millions of people who acquire all sorts of wonderful feelings from watching a football game and drinking a bottle of beer. It makes them really happy. Doesn’t do shit for me. But for them it’s life itself. As long as they can believe in the beer and the football, then they’ve really got something. And it’s probably more useful to them than religion. So why take it away? Why tell them what’s really going on? Let ’em be happy.

Context: Communism forgets that life is individual. Capitalism forgets that life is social, and the kingdom of brotherhood is found neither in the thesis of communism nor the antithesis of capitalism but in a higher synthesis. It is found in a higher synthesis that combines the truths of both. Now, when I say question the whole society, it means ultimately coming to see that the problem of racism, the problem of exploitation, and the problem of war are all tied together. These are the triple evils that are interrelated.

Men and Manners: Sketches and Essays (1852)

Context: The multitude of men and women choose the less adventurous way of the comparatively unconscious civic and tribal routines. But these seekers, too, are saved—by the virtue of the inherited symbolic aids of society, the rites of passage, the grace-yielding sacraments, given to mankind of old by the redeemers and handed down through the millenniums. It is only those who know neither an inner call nor an outer doctrine whose plight is truly desperate; that is to say, most of us today, in this labyrinth without and within the heart. Alas, where is the guide, that fond virgin, Ariadne, to supply the simple clue that will give us the courage to face the Minotaur, and the means to find our way to freedom when the monster has been met and slain?

Yes, Virginia, there is a Santa Claus (1897)
Context: Not believe in Santa Claus! You might as well not believe in fairies! You might get your papa to hire men to watch in all the chimneys on Christmas Eve to catch Santa Claus, but even if they did not see Santa Claus coming down, what would that prove? Nobody sees Santa Claus, but that is no sign that there is no Santa Claus. The most real things in the world are those that neither children nor men can see. Did you ever see fairies dancing on the lawn? Of course not, but that's no proof that they are not there. Nobody can conceive or imagine all the wonders there are unseen and unseeable in the world.
You may tear apart the baby's rattle and see what makes the noise inside, but there is a veil covering the unseen world which not the strongest man, nor even the united strength of all the strongest men that ever lived, could tear apart. Only faith, fancy, poetry, love, romance, can push aside that curtain and view and picture the supernal beauty and glory beyond. Is it all real? Ah,, in all this world there is nothing else real and abiding.
No Santa Claus! Thank, nay, ten times ten thousand years from now, he will continue to make glad the heart of childhood.
