"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..."

“Listen, are we helpless? Are we doomed to do it again and again and again? Have we no choice but to play the Phoenix in an unending sequence of rise and fall? Assyria, Babylon, Egypt, Greece, Carthage, Rome, the Empires of Charlemagne and the Turk: Ground to dust and plowed with salt. Spain, France, Britain, America — burned into the oblivion of the centuries. And again and again and again. Are we doomed to it, Lord, chained to the pendulum of our own mad clockwork, helpless to halt its swing? This time, it will swing us clean to oblivion, he thought.”

“Abbot Zerchi smiled thinly. 'You don't have a soul, Doctor. You are a soul. You have a body, temporarily.'”

“The old man was sad as he sat on his porch. He knew so little of the Great Purpose. Why must his seed fling itself starward? He knew that it must — but he lacked a reason. His grandchildren played in the twilight, played space-games, although there was not yet a starship on the planet.”

“Whatever you specialize in, another specialty will either gobble you, or find a way to replace you. If you get what looks like a secure niche, somebody'll come along and wall you up in it and write your epitaph on it. And the more specialized a society gets, the more dangerous it is for the pure specialist. You think an electronic engineer in any safer than an actor? Or a ditch-digger?”

“Objective evidence is the ultimate authority. Recorders may lie, but Nature is incapable of it.”

“When Holy Church occasionally hinted that she still considered her authority to be supreme over all nations and superior to the authority of states, men in these times tended to snicker.”
