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

“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.”

“You can either have high specific intelligence or high general intelligence, but not both.”

“Beauty is power and elegance, right action, form fitting function, intelligence, and reasonability. And very often expressed in curves.”

“We have to start doing this in ignorance of the details of how to do it. We have to learn how to do it in the attempt itself. It is something we are going to have to imagine.”

“We will go out into the world and plant gardens and orchards to the horizons, we will build roads through the mountains and across the deserts, and terrace the mountains and irrigate the deserts until there will be garden everywhere, and plenty for all, and there will be no more empires or kingdoms, no more caliphs, sultans, emirs, khans, or zamindars, no more kings or queens or princes, no more quadis or mullahs or ulema, no more slavery and no more usury, no more property and no more taxes, no more rich and no more poor, no killing or maiming or torture or execution, no more jailers and no more prisoners, no more generals, soldiers, armies or navies, no more patriarchy, no more caste, no more hunger, no more suffering than what life brings us for being born and having to die, and then we will see for the first time what kind of creatures we really are.”

“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.”
