Context: At no time has the world been without war. Not in seven or ten or twenty thousand years. Neither the wisest of leaders, nor the noblest of kings, nor yet the Church — none of them has been able to stop it. And don't succumb to the facile belief that wars will be stopped by hotheaded socialists. Or that rational and just wars can be sorted out from the rest. There will always be thousands of thousands to whom even such a war will be senseless and unjustified. Quite simply, no state can live without war, that is one of the state's essential functions. … War is the price we pay for living in a state. Before you can abolish war you will have to abolish all states. But that is unthinkable until the propensity to violence and evil is rooted out of human beings. The state was created to protect us from evil. In ordinary life thousands of bad impulses, from a thousand foci of evil, move chaotically, randomly, against the vulnerable. The state is called upon to check these impulses — but it generates others of its own, still more powerful, and this time one-directional. At times it throws them all in a single direction — and that is war.

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.

Ch 6
A Canticle for Leibowitz (1959), Fiat Homo
Context: The monks of the earliest days had not counted on the human ability to generate a new cultural inheritance in a couple of generations if an old one is utterly destroyed, to generate it by virtue of lawgivers and prophets, geniuses or maniacs; through a Moses, or through a Hitler, or an ignorant but tyrannical grandfather, a cultural inheritance may be acquired between dusk and dawn, and many have been so acquired. But the new "culture" was an inheritance of darkness, wherein "simpleton" meant the same thing as "citizen" meant the same thing as "slave." The monks waited. It mattered not at all to them that the knowledge they saved was useless, that much of it was not really knowledge now, was as inscrutable to the monks in some instances as it would be to an illiterate wild-boy from the hills; this knowledge was empty of content, its subject matter long since gone. Still, such knowledge had a symbolic structure that was peculiar to itself, and at least the symbol-interplay could be observed. To observe the way a knowledge-system is knit together is to learn at least a minimum knowledge-of-knowledge, until someday — someday, or some century — an Integrator would come, and things would be fitted together again. So time mattered not at all. The Memorabilia was there, and it was given to them by duty to preserve, and preserve it they would if the darkness in the world lasted ten more centuries, or even ten thousand years...
