“A work will be treated as art within a certain circle – that is, within the circle of let's say ten thousand people. There are about ten thousand in the world today who are prepared to take it on face value if you present anything to them as art, they deal with it straight on as art and tell you whether it stimulates them, moves them, or not. Some of them might even buy it... Anyway, it seems to me that within that ring of ten thousand, fortunately, that sincerity issue [the issue: is something art or not] is over. The reason why that issue failed is that it became obvious no one would live a life of art, a life of poverty, just to pull somebody's legs. In other words, there were compensating sacrifices for what people did.”

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...

Johnny Got His Gun (1938)
Context: Put the guns into our hands and we will use them. Give us the slogans and we will turn them into realities. Sing the battle hymns and we will take them up where you left off. Not one, not ten, not ten thousand, not a million, not ten millions, not a hundred millions but a billion, two billions of us all — the people of the world. We will have the slogans and we will have the hymns and we will have the guns and we will use them and we will live. Make no mistake of it, we will live. We will be alive and we will walk and talk and eat and sing and laugh and feel and love and bear our children in tranquillity, in security, in decency, in peace. You plan the wars, you masters of men — plan the wars and point the way and we will point the gun.

Anabasis
Context: On making prisoners of our generals, they expected that we should perish from want of direction and order. It is incumbent, therefore, on our present commanders to be far more vigilant than our former ones, and on those under command to be far more orderly, and more obedient to their officers, at present than they were before…On the very day that such resolution is passed, they will see before them ten thousand Clearchuses instead of one.
