“This seemed to calm Isaac down, though he did not apologize for having thought the worst about Daniel. He said something along the lines of: “Heavenly radiance fills the aether, its rays parallel and straight and, so long as nothing is there to interrupt them, invisible. The secrets of God’s creation are all told by those rays, but told in a language we do not understand, or even hear—the direction from which they shine, the spectrum of colors concealed within the light, these are all characters in a cryptogram. The gnomon—look at our shadows on the Green! We are the gnomon. We interrupt that light and we are warmed and illuminated by it. By stopping the light, we destroy part of the message without understanding it. We cast a shadow, a hole in the light, a ray of darkness that is shaped like ourselves—some might say that it contains no information save the profile of our own forms—but they are wrong. By recording the stretching and skewing of our shadows, we can attain part of the knowledge hidden in the cryptogram. All we need to make the necessary observations is a fixed regular surface—a plane—against which to cast the shadow. Descartes gave us the plane.”

“The flowing river
never stops
and yet the water
never stays the same.

Foam floats
upon the pools,
scattering, re-forming,
never lingering long.

So it is with man
and all his dwelling places
here on earth”
― Kamo no Chōmei, Hojoki: Visions of a Torn World

“Books reflect interests; interests inform personality and personality decides a course of action.”

“Can’t machines build these faster?” he asked the woman, looking around the starship shell.“Why, of course!” she laughed.“Then why do you do it?”“It’s fun. You see one of these big mothers sail out those doors for the first time, heading for deep space, three hundred people on board, everything working, the Mind quite happy, and you think, I helped build that. The fact a machine could have done it faster doesn’t alter the fact that it was you who actually did it.”
“Hmm,” he said.
“Well, you may ‘hmm’ as you wish,” the woman said, approaching a translucent hologram of the half-completed ship, where a few other construction workers were standing, pointing inside the model and talking. “But have you ever been gliding or swum underwater?”
“Yes,” he agreed.
The woman shrugged. “Yet birds fly better than we do, and fish swim better. Do we stop gliding or swimming because of this?”
He smiled. “I suppose not.”
“You suppose correctly,” the woman said. “And why?” She looked at him, grinning. “Because it’s fun.”
