“We must be careful not to discourage our twelve-year-olds by making them waste the best years of their lives preparing for examinations.”
― Freeman Dyson, Infinite in All Directions

“The public has a distorted view of science because children are taught in school that science is a collection of firmly established truths. In fact, science is not a collection of truths. It is a continuing exploration of mysteries.”
― Freeman John Dyson

“It is remarkable that mind enters into our awareness of nature on two separate levels. At the highest level, the level of human consciousness, our minds are somehow directly aware of the complicated flow of electrical and chemical patterns in our brains. At the lowest level, the level of single atoms and electrons, the mind of an observer is again involved in the description of events. Between lies the level of molecular biology, where mechanical models are adequate and mind appears to be irrelevant. But I, as a physicist, cannot help suspecting that there is a logical connection between the two ways in which mind appears in my universe. I cannot help thinking that our awareness of our own brains has something to do with the process which we call "observation" in atomic physics. That is to say, I think our consciousness is not just a passive epiphenomenon carried along by the chemical events in our brains, but is an active agent forcing the molecular complexes to make choices between one quantum state and another. In other words, mind is already inherent in every electron, and the processes of human consciousness differ only in degree but not in kind from the processes of choice between quantum states which we call "chance" when they are made by electrons.”

“Science is my territory, but science fiction is the landscape of my dreams.”
― Freeman John Dyson, Imagined Worlds

“The more I examine the universe and the details of its architecture, the more evidence I find that the universe in some sense must have known we were coming.”
― Freeman John Dyson

“The technologies which have had the most profound effects on human life are usually simple. A good example of a simple technology with profound historical consequences is hay. Nobody knows who invented hay, the idea of cutting grass in the autumn and storing it in large enough quantities to keep horses and cows alive through the winter. All we know is that the technology of hay was unknown to the Roman Empire but was known to every village of medieval Europe. Like many other crucially important technologies, hay emerged anonymously during the so-called Dark Ages. According to the Hay Theory of History, the invention of hay was the decisive event which moved the center of gravity of urban civilization from the Mediterranean basin to Northern and Western Europe. The Roman Empire did not need hay because in a Mediterranean climate the grass grows well enough in winter for animals to graze. North of the Alps, great cities dependent on horses and oxen for motive power could not exist without hay. So it was hay that allowed populations to grow and civilizations to flourish among the forests of Northern Europe. Hay moved the greatness of Rome to Paris and London, and later to Berlin and Moscow and New York.”

“It is our task, both in science and in society at large, to prove the conventional wisdom wrong and to make our unpredictable dreams come true”
― Freeman Dyson

“A good scientist is a person with original ideas. A good engineer is a person who makes a design that works with as few original ideas as possible.”
― Freeman Dyson

“It is better to be wrong than to be vague.”
― Freeman Dyson

“It is characteristic of all deep human problems that they are not to be
approached without some humor and some bewilderment.”
― Freeman John Dyson, Disturbing the Universe

“The glory of science is to imagine more than we can prove.”
― Freeman Dyson

“The whole point of science is that most of it is uncertain. That's why science is exciting--because we don't know. Science is all about things we don't understand. The public, of course, imagines science is just a set of facts. But it's not. Science is a process of exploring, which is always partial. We explore, and we find out things that we understand. We find out things we thought we understood were wrong. That's how it makes progress.”
― Freeman Dyson

“The conservative has little to fear from the man whose reason is the servant of his passions, but let him beware of him in whom reason has become the greatest and most terrible of passions. These are the wreckers of outworn empires.”
― Freeman John Dyson

“If science ceases to be a rebellion against authority, then it does not deserve the talents of our brightest children.”
― Freeman Dyson, The Scientist as Rebel

“The reason Dick's physics was so hard for ordinary people to grasp was that he did not use equations. The usual theoretical physics was done since the time of Newton was to begin by writing down some equations and then to work hard calculating solutions of the equations. This was the way Hans and Oppy and Julian Schwinger did physics. Dick just wrote down the solutions out of his head without ever writing down the equations. He had a physical picture of the way things happen, and the picture gave him the solutions directly with a minimum of calculation. It was no wonder that people who had spent their lives solving equations were baffled by him. Their minds were analytical; his was pictorial.”
― Freeman Dyson

“The nonliving universe is as diverse and as dynamic as the living universe, and is also dominated by patterns of organization that are not yet understood.”
― Freeman Dyson

“The beauty in the genome is of course that it's so small. The human genome is only on the order of a gigabyte of data...which is a tiny little database. If you take the entire living biosphere, that's the assemblage of 20 million species or so that constitute all the living creatures on the planet, and you have a genome for every species the total is still about one petabyte, that's a million gigabytes - that's still very small compared with Google or the Wikipedia and it's a database that you can easily put in a small room, easily transmit from one place to another. And somehow mother nature manages to create this incredible biosphere, to create this incredibly rich environment of animals and plants with this amazingly small amount of data.”
― Freeman Dyson

“Much of the history of science, like the history of religion, is a history of struggles driven by power and money. And yet this is not the whole story. Genuine saints occasionally play an important role, both in religion and in science. Einstein was an important figure in the history of science, and he was a firm believer in transcendence. For Einstein, science as a way of escape from mundane reality was no pretense. For many scientists less divinely gifted than Einstein, the chief reward for being a scientist is not the power and the money but the chance of catching a glimpse of the transcendent beauty of nature.”
― Freeman Dyson, The Scientist as Rebel

“We do not need to have an agreed set of goals before we do something ambitious!”
― Freeman John Dyson, From Eros to Gaia

“The essential fact which emerges ... is that the three smallest and most active reservoirs ( of carbon in the global carbon cycle), the atmosphere, the plants and the soil, are all of roughly the same size. This means that large human disturbance of any one of these reservoirs will have large effects on all three. We cannot hope either to understand or to manage the carbon in the atmosphere unless we understand and manage the trees and the soil too.”
― Freeman Dyson, From Eros to Gaia

“No matter how far we go into the future, there will always be new things happening, new information coming in, new worlds to explore, a constantly expanding domain of life, consciousness, and memory.”
― Freeman Dyson

“As a working hypothesis to explain the riddle of our existence, I propose that our universe is the most interesting of all possible universes, and our fate as human beings is to make it so”
― Freeman Dyson

“Sanity is, in essence, nothing more than the ability to live in harmony with nature's laws.”
― Freeman Dyson, Disturbing the Universe

“We must regard science, then, from three points of view. First, it is the free activity of man's divine faculties of reason and imagination. Secondly, it is the answer of the few to the demands of the many for wealth, comfort and victory, gifts which it will grant only in exchange for peace, security and stagnation. Finally it is man's gradual conquest, first of space and time, the of matters as such, then of his own body and those of other living beings, and finally the subjugation of the dark and evil elements in his own soul.”
― Freeman Dyson, The Scientist as Rebel

“For many scientists less divinely gifted than Einstein,the chief reward for being a scientist is not the power and the money but the chance of catching a glimpse of the transcendent beauty of nature.”

“To give us room to explore the varieties of mind and body into which our genome can evolve, one planet is not enough.”
― Freeman Dyson

“Samuel Gompers was the founder and first president of the American Federation of Labor. He established in America the tradition of practical bargaining between labor and management which led to an era of growth and prosperity for labor unions. Now, seventy years after Gomper's death, the unions have dwindled, while his dreams-more books and fewer guns, more leisure and less greed, more schoolhouses and fewer jails-have been tacitly abandoned. In a society without social justice and with a free-market ideology, guns, greed, and jails are bound to win.”

“The question that will decide our destiny is not whether we shall expand into space. It is: shall we be one species or a million? A million species will not exhaust the ecological niches that are awaiting the arrival of intelligence.”
― freeman dyson

“We should try to introduce our children to science today as a rebellion against poverty and ugliness and militarism and economic injustice.”
― Freeman Dyson, The Scientist as Rebel

“Any society which idolizes soldiers is tainted with a collective insanity and is likely in the end to come to grief.”
― Freeman Dyson, The Scientist as Rebel
