„The real world is muddy and messy and full of things that we do not yet understand.“

—  Freeman Dyson
Context: My first heresy says that all the fuss about global warming is grossly exaggerated. Here I am opposing the holy brotherhood of climate model experts and the crowd of deluded citizens who believe the numbers predicted by the computer models. Of course, they say, I have no degree in meteorology and I am therefore not qualified to speak. But I have studied the climate models and I know what they can do. The models solve the equations of fluid dynamics, and they do a very good job of describing the fluid motions of the atmosphere and the oceans. They do a very poor job of describing the clouds, the dust, the chemistry and the biology of fields and farms and forests. They do not begin to describe the real world that we live in. The real world is muddy and messy and full of things that we do not yet understand. It is much easier for a scientist to sit in an air-conditioned building and run computer models, than to put on winter clothes and measure what is really happening outside in the swamps and the clouds. That is why the climate model experts end up believing their own models.

„Scientifically speaking, a butterfly is at least as mysterious as a superstring.“

—  Freeman Dyson
Context: Scientifically speaking, a butterfly is at least as mysterious as a superstring. When something ceases to be mysterious it ceases to be of absorbing interest to scientists. Almost all things scientists think and dream about are mysterious. Ch. 2 : Butterflies and Superstrings, p. 14

„What was needed was a little more human charity, a little more willingness to listen rather than to lay down the law, a little more humility. Scientists stand in need of these Christian virtues just as much as preachers do.“

—  Freeman Dyson
Context: There is no easy solution to the conflict between fundamentalist Christian dogma and the facts of biological evolution. I am not saying that the conflict could have been altogether avoided. I am saying only that the conflict was made more bitter and more damaging, both to religion and to science, by the dogmatic and self-righteousness of scientists. What was needed was a little more human charity, a little more willingness to listen rather than to lay down the law, a little more humility. Scientists stand in need of these Christian virtues just as much as preachers do. Ch. 1 : In Praise of Diversity

„To talk about the end of science is just as foolish as to talk about the end of religion. Science and religion are both still close to their beginnings, with no ends in sight.“

—  Freeman Dyson
Context: To talk about the end of science is just as foolish as to talk about the end of religion. Science and religion are both still close to their beginnings, with no ends in sight. Science and religion are both destined to grow and change in the millennia that lie ahead of us, perhaps solving some old mysteries, certainly discovering new mysteries of which we yet have no inkling.

„The dominance of grey technology is now coming to an end.“

—  Freeman Dyson
Context: All through our history, we have been changing the world with our technology. Our technology has been of two kinds, green and grey. Green technology is seeds and plants, gardens and vineyards and orchards, domesticated horses and cows and pigs, milk and cheese, leather and wool. Grey technology is bronze and steel, spears and guns, coal and oil and electricity, automobiles and airplanes and rockets, telephones and computers. Civilization began with green technology, with agriculture and animal-breeding, ten thousand years ago. Then, beginning about three thousand years ago, grey technology became dominant, with mining and metallurgy and machinery. For the last five hundred years, grey technology has been racing ahead and has given birth to the modern world of cities and factories and supermarkets. The dominance of grey technology is now coming to an end.

„I have to clear away a few popular misconceptions about space as a habitat … It is generally considered that planets are important. Except for Earth, they are not.“

—  Freeman Dyson
Context: I have to clear away a few popular misconceptions about space as a habitat … It is generally considered that planets are important. Except for Earth, they are not. Mars is waterless, and the others are, for various reasons, basically inhospitable to man. It is generally considered that beyond the sun’s family of planets there is absolute emptiness extending for light-years until you come to another star. In fact, it is likely that the space around the solar system is populated by huge numbers of comets, small worlds a few miles in diameter, rich in water and the other chemicals essential to life. Part IV: Personal and Philosophical Essays, Ch. 24 : "The World, the Flesh, and the Devil" (1972)

„It is characteristic of all deep human problems that they are not to be approached without some humor and some bewilderment.“

—  Freeman Dyson
Context: It is characteristic of all deep human problems that they are not to be approached without some humor and some bewilderment. <!-- Pt. 1, Ch. 1

„The progress of science requires the growth of understanding in both directions, downward from the whole to the parts and upward from the parts to the whole.“

—  Freeman Dyson
Context: The progress of science requires the growth of understanding in both directions, downward from the whole to the parts and upward from the parts to the whole. A reductionist philosophy, arbitrarily proclaiming that the growth of understanding must go only in one direction, makes no scientific sense. Indeed, dogmatic philosophical beliefs of any kind have no place in science. Part I : Contemporary Issues in Science, Ch. 1 : "The Scientist as Rebel"

„There’s very good news from the asteroids. It appears that a large fraction of them, including the big ones, are actually very rich in H2O.“

—  Freeman Dyson
Context: There’s very good news from the asteroids. It appears that a large fraction of them, including the big ones, are actually very rich in H2O. Nobody imagined that. They thought they were just big rocks … It’s easier to get to an asteroid than to Mars, because the gravity is lower and landing is easier. Certainly the asteroids are much more practical, right now. If we start space colonies in, say, the next 20 years, I would put my money on the asteroids. As quoted in "The Danger of Cosmic Genius" https://www.theatlantic.com/magazine/archive/2010/12/the-danger-of-cosmic-genius/308306/ by Kenneth Brower, The Atlantic (December 2010)
