“Consider cotton prices," Malcolm said. "There are good records of cotton prices going back more than a hundred years. When you study fluctuations in cotton prices, you find that the graph of price fluctuations in the course of a day looks basically like the graph for a week, which looks basically like the graph for a year, or for ten years. And that's how things are. A day is like a whole life. You start out doing one thing, but end up doing something else, plan to run an errand, but never get there... And at the end of your life, your whole existence has that same haphazard quality, too. Your whole life has the same shape as a single day.”

“And that's how things are. A day is like a whole life. You start out doing one thing, but end up doing something else, plan to run an errand, but never get there. . . . And at the end of your life, your whole existence has the same haphazard quality, too. Your whole life has the same shape as a single day.”

“Ellie said, "Isn't it a little warm for black?"You're extremely pretty, Dr. Sattler," he said. "I could look at your legs all day. But no, as a matter of fact, black is an excellent color for heat. If you remember your black-body radiation, black is actually best in heat. Efficient radiation. In any case, I wear only two colors, black and gray."Ellie was staring at him, her mouth open. "These colors are appropriate for any occasion," Malcolm continued, and they go well together, should I mistakenly put on a pair of gray socks with my black trousers."But don't you find it boring to wear only two colors?"Not at all. I find it liberating. I believe my life has value, and I don't want to waste it thinking about clothing," Malcolm said. "I don't want to think about what I will wear in the morning. Truly, can you imagine anything more boring than fashion? Professional sports, perhaps. Grown men swatting little balls, while the rest of the world pays money to applaud. But, on the whole, I find fashion even more tedious than sports."Dr. Malcolm," Hammond explained, "is a man of strong opinions."And mad as a hatter," Malcolm said cheerfully. "But you must admit, these are nontrivial issues. We live in a world of frightful givens. It is given that you will behave like this, given that you will care about that. No one thinks about the givens. Isn't it amazing? In the information society, nobody thinks. We expected to banish paper, but we actually banished thought.”

“A hundred years from now, people will look back on us and laugh. They'll say, 'You know what people used to believe? They believed in photons and electrons. Can you imagine anything so silly?' They'll have a good laugh, because by then there will be newer better fantasies... And meanwhile, you feel the way the boat moves? That's the sea. That's real. You smell the salt in the air? You feel the sunlight on your skin? That's all real. Life is wonderful. It's a gift to be alive, to see the sun and breathe the air. And there isn't really anything else.”

“You think man can destroy the planet? What intoxicating vanity. Let me tell you about our planet. Earth is four-and-a-half-billion-years-old. There's been life on it for nearly that long, 3.8 billion years. Bacteria first; later the first multicellular life, then the first complex creatures in the sea, on the land. Then finally the great sweeping ages of animals, the amphibians, the dinosaurs, at last the mammals, each one enduring millions on millions of years, great dynasties of creatures rising, flourishing, dying away -- all this against a background of continuous and violent upheaval. Mountain ranges thrust up, eroded away, cometary impacts, volcano eruptions, oceans rising and falling, whole continents moving, an endless, constant, violent change, colliding, buckling to make mountains over millions of years. Earth has survived everything in its time. It will certainly survive us. If all the nuclear weapons in the world went off at once and all the plants, all the animals died and the earth was sizzling hot for a hundred thousand years, life would survive, somewhere: under the soil, frozen in Arctic ice. Sooner or later, when the planet was no longer inhospitable, life would spread again. The evolutionary process would begin again. It might take a few billion years for life to regain its present variety. Of course, it would be very different from what it is now, but the earth would survive our folly, only we would not. If the ozone layer gets thinner, ultraviolet radiation sears the earth, so what? Ultraviolet radiation is good for life. It's powerful energy. It promotes mutation, change. Many forms of life will thrive with more UV radiation. Many others will die out. Do you think this is the first time that's happened? Think about oxygen. Necessary for life now, but oxygen is actually a metabolic poison, a corrosive glass, like fluorine. When oxygen was first produced as a waste product by certain plant cells some three billion years ago, it created a crisis for all other life on earth. Those plants were polluting the environment, exhaling a lethal gas. Earth eventually had an atmosphere incompatible with life. Nevertheless, life on earth took care of itself. In the thinking of the human being a hundred years is a long time. A hundred years ago we didn't have cars, airplanes, computers or vaccines. It was a whole different world, but to the earth, a hundred years is nothing. A million years is nothing. This planet lives and breathes on a much vaster scale. We can't imagine its slow and powerful rhythms, and we haven't got the humility to try. We've been residents here for the blink of an eye. If we're gone tomorrow, the earth will not miss us.”

“Kids are more advanced these days. The teenage years now start at 11.”

“One day," she told us, "you'll have to leave here and go out into the big world out there and earn your living like everyone else. To do that you need to learn. The more you learn now, the more interesting your life will be.”
