"When Brother Francis had removed the last tray, he touched the papers reverently: only a handful of folded documents here, and yet a treasure; for they had escaped the angry flames of the Simplification, wherein even sacred writings had curled, blackened, and withered into smoke while ignorant mobs howled and hailed it a triumph. He handled the papers as one might handle holy things, shielding them from the wind with his habit, for all were brittle and cracked from age. There was a sheaf of rough sketches and diagrams. There were hand-scribbled notes, two large folded papers, and a small book entitled Memo."

“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.”
