“Economics was like psychology, a pseudoscience trying to hide that fact with intense theoretical hyperelaboration. And gross domestic product was one of those unfortunate measurement concepts, like inches or the British thermal unit, that ought to have been retired long before.”

“Sad but true: individual intelligence probably peaked in the Upper Paleolithic, and we have been self-domesticated creatures ever since”

“It was that sort of sleep in which you wake every hour and think to yourself that you have not been sleeping at all; you can remember dreams that are like reflections, daytime thinking slightly warped.”

“Must redefine utopia. It isn't the perfect end-product of our wishes, define it so and it deserves the scorn of those who sneer when they hear the word. No. Utopia is the process of making a better world, the name for one path history can take, a dynamic, tumultuous, agonizing process, with no end. Struggle forever.Compare it to the present course of history. If you can.”

“Oh God," Coyote said, and rolled onto his side, propping his head up on one hand. "It's hard to remember something that long ago. It's almost like an epic poem I memorized once, and can barely recite anymore.”

“It makes us a thread in a tapestry that has unrolled for centuries before us, and will unroll for centuries after us. We're midway through the loom, that's the present, and what we do casts the thread in a particular direction, and the picture of the tapestry changes accordingly. When we begin to to try to make a picture pleasing to us and to those who come after, then perhaps you can say that we have seized history.”

“He pointed to another number, changing as rapidly as the first, but on a lower trajectory; it rose to a high of 8.79 rem per hour. Several lifetimes of dentists’ X-rays, to be sure; but the radiation outside the storm shelter would have been a lethal dose, so they were getting off lightly. Still, the amount flying through the rest of the ship! Billions of particles were penetrating the ship and colliding with the atoms of water and metal they were huddled behind; hundreds of millions were flying between these atoms and then through the atoms of their bodies, touching nothing, as if they were no more than ghosts. Still, thousands were striking atoms of flesh and bone. Most of those collisions were harmless; but in all those thousands, there were in all probability one or two (or three?) in which a chromosome strand was taking a hit, and kinking in the wrong way: and there it was. Tumor initiation, begun with just that typo in the book of the self. And years later, unless the victim's DNA luckily repaired itself, the tumor promotion that was a more or less unavoidable part of living would have its effect, and there would appear a bloom of Something Else inside: cancer. Leukemia, most likely; and, most likely, death.”
