Carl Sagan Quotes

“Sherrie described atheism as a positive system of belief—one based on data, exploration and observation rather than scripture, creed and prayer. Atheists believe that human life is a chemical phenomenon, that our first parents were super-novas that happened billions of years ago—that humans are inexplicable miracles in a universe of structured chaos. Atheists believe that when we die, we will turn into organic debris which will continue cycling for billions of years in various incarnations. Sherrie explained that atheists appreciate life unfathomably because it is going to end. No one who takes atheism seriously dies without hope.”

“Can you be sure that others have not come before you and destroyed the pristine state of the native myth? Can you be sure that the natives are not humoring you or pulling your leg? Bronislaw Malinowski thought he had discovered a people in the Trobriant Islands who had not worked out the connection between sexual intercourse and childbirth. When asked how children were conceived, they supplied him with an elaborate mythic structure prominently featuring celestial intervention. Amazed, Malinowski objected that was not how it was done at all, and supplied them instead with the version so popular in the West today – including a nine-month gestation period. “Impossible,” replied the Melanesians. “Do you not see that woman over there with her six-month-old child? Her husband has been on an extended voyage to another island for two years.” Is it more likely that the Melanesians were ignorant of the begetting of children or that they were gently chiding Malinowski? If some peculiar-looking stranger came into my town and asked ME where babies came from, I’d certainly be tempted to tell him about storks and cabbages. Prescientific people are people. Individually they are as clever as we are.”

“CARL SAGAN SAID that if you want to make an apple pie from scratch, you must first invent the universe. When he says “from scratch,” he means from nothing. He means from a time before the world even existed. If you want to make an apple pie from nothing at all, you have to start with the Big Bang and expanding universes, neutrons, ions, atoms, black holes, suns, moons, ocean tides, the Milky Way, Earth, evolution, dinosaurs, extinction- level events, platypuses, Homo erectus, Cro- Magnon man, etc. You have to start at the beginning. You must invent fire. You need water and fertile soil and seeds. You need cows and people to milk them and more people to churn that milk into butter. You need wheat and sugar cane and apple trees. You need chemistry and biology. For a really good apple pie, you need the arts. For an apple pie that can last for generations, you need the printing press and the Industrial Revolution and maybe even a poem.To make a thing as simple as an apple pie, you have to create the whole wide world.”

“Plato and Aristotle were comfortable in a slave society. They offered justification for oppression. They served tyrants. They taught the alienation of the body from the mind (a natural enough ideal in a slave society); they separated matter from thought; they divorced the Earth from the heavens - divisions that were to dominate Western thinking for more than twenty centuries. Plato, who believed that 'all things are full of gods,' actually used the metaphor of slavery to connect his politics with his cosmology. He is said to have urged the burning of all of the books of Democritus (he had a similar recommendation for the books of Homer), perhaps because Democritus did not acknowledge immortal souls or immortal gods or Pythagorean mysticism, or because he believed in an infinite number of worlds. Of the seventy-three books Democritus is said to have written, covering all of human knowledge, not a single work survives. All we know is from fragments, chiefly on ethics, and secondhand accounts. The same is true of almost all the other ancient Ionian scientists.”

“One consequence of this train of argument is that, even if civilizations commonly arise on planets throughout the Galaxy, few of them will be both long-lived and nontechnological. Since hazards from asteroids and comets must apply to inhabited planets all over the Galaxy, if there are such, intelligent beings everywhere will have to unify their home worlds politically, leave their planets, and move small nearby worlds around. Their eventual choice, as ours, is spaceflight or extinction.”

“The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand. It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we’ve ever known.”

“The scope and audacity of John Kennedy’s May 25, 1961, message to a joint session of Congress on “Urgent National Needs”—the speech that launched the Apollo program—dazzled me. We would use rockets not yet designed and alloys not yet conceived, navigation and docking schemes not yet devised, in order to send a man to an unknown world—a world not yet explored, not even in a preliminary way, not even by robots—and we would bring him safely back, and we would do it before the decade was over. This confident pronouncement was made before any American had even achieved Earth orbit.”

“My main reason for scepticism about the Huxley/Sagan theory is that the human brain is demonstrably eager to see faces in random patterns, as we know from scientific evidence, on top of the numerous legends about faces of Jesus, or the Virgin Mary, or Mother Teresa, being seen on slices of toast, or pizzas, or patches of damp on a wall. This eagerness is enhanced if the pattern departs from randomness in the specific direction of being symmetrical.”

“I don't think science is hard to teach because humans aren't ready for it, or because it arose only through a fluke, or because, by and large, we don't have the brainpower to grapple with it. Instead, the enormous zest for science that I see in first-graders and the lesson from the remnant hunter-gatherers both speak eloquently: A proclivity for science is embedded deeply within us, in all times, places, and cultures. It has been the means for our survival. It is our birthright. When, through indifference, inattention, incompetence, or fear of skepticism, we discourage children from science, we are disenfranchising them, taking from them the tools needed to manage their future.”

“Every now and then, I'm lucky enough to teach a kindergarten or first-grade class. Many of these children are natural-born scientists - although heavy on the wonder side, and light on skepticism. They're curious, intellectually vigorous. Provocative and insightful questions bubble out of them. They exhibit enormous enthusiasm. I'm asked follow-up questions. They've never heard of the notion of a 'dumb question'. But when I talk to high school seniors, I find something different. They memorize 'facts'. By and large, though, the joy of discovery, the life behind those facts has gone out of them. They've lost much of the wonder and gained very little skepticism. They're worried about asking 'dumb' questions; they are willing to accept inadequate answers, they don't pose follow-up questions, the room is awash with sidelong glances to judge, second-by-second, the approval of their peers. They come to class with their questions written out on pieces of paper, which they surreptitiously examine, waiting their turn and oblivious of whatever discussion their peers are at this moment engaged in. Something has happened between first and twelfth grade. And it's not just puberty. I'd guess that it's partly peer pressure not to excel - except in sports, partly that the society teaches short-term gratification, partly the impression that science or mathematics won't buy you a sports car, partly that so little is expected of students, and partly that there are few rewards or role-models for intelligent discussion of science and technology - or even for learning for it's own sake. Those few who remain interested are vilified as nerds or geeks or grinds. But there's something else. I find many adults are put off when young children pose scientific questions. 'Why is the Moon round?', the children ask. 'Why is grass green?', 'What is a dream?', 'How deep can you dig a hole?', 'When is the world's birthday?', 'Why do we have toes?'. Too many teachers and parents answer with irritation, or ridicule, or quickly move on to something else. 'What did you expect the Moon to be? Square?' Children soon recognize that somehow this kind of question annoys the grown-ups. A few more experiences like it, and another child has been lost to science.”

“Just as there are those who accept every UFO report at face value, there are also those who dismiss the idea of alien visitation out of hand and with great passion. It is, they say, unnecessary to examine the evidence, and “unscientific” even to contemplate the issue. I once helped to organize a public debate at the annual meeting of the American Association for the Advancement of Science between proponent and opponent scientists of the proposition that some UFOs were spaceships; whereupon a distinguished physicist, whose judgment in many other matters I respected, threatened to sic the Vice President of the United States on me if I persisted in this madness. (Nevertheless, the debate was held and published, the issues were a little better clarified, and I did not hear from Spiro T. Agnew.)”

“Russell’s Teapot (Celestial Teapot Analogy) We cannot equate Russell’s teapot idea with the idea of God. Although this idea is humorous, it isn't very sensible. If anybody without scientific credentials stated thoughtfully that the teapot is circling the Sun, the majority of people would think that a person saying that is either bipolar, schizophrenic, or suffers from some other mental illness. This kind of comparison is absurd. Comic and absurdist comparisons of this kind only muddy the waters. Proof or disproof of such a thing is unnecessary because almost everybody knows the teapot can't orbit the Sun as freely as planets on a microcosmic or macro level. Regardless of Russel being aware that his example is nonsense, he still used it (and he states that). The point was not to prove anything but to make a funny remark to diminish the subject of the attack, God. It is a logical fallacy whenever we use such tactics or tricks because we use witty comments for lacking something more potent. If we make fun of some ideas, it does not mean they have no value. We cannot destroy an idea that has existed for millennia by witty but silly arguments. Carl Sagan made an even sillier argument about the undetectable dragon in his garage. To compare the idea of God to the teapot or a dragon in a garage is a useless way to refute an idea or argument with an “argument” (example) in the form of funny irony. I admire Bertrand Russell and Carl Sagan for their ingenuity and insights. I also admire Bertrand Russell’s writing style because he could express complicated ideas and concepts in very readable and clear prose. There can be no comparison between the idea of God and a teapot floating around the Sun or between God and an unidentifiable dragon in the garage. We cannot base our arguments on the value of their wit because regardless of how witty the statement is, it has to stand the test of truth, not the test of wit. We can easily exclude the idea of a teapot floating in orbit around the Sun as ridiculous. The same applies to the argument about the dragon in a garage. But can we exclude the idea of God from religious and theological thoughts and serious philosophical inquiries interested in discovering the truth about the world and God? We can easily refuse to accept a teapot or dragon in the garage as serious arguments. However, we cannot a priori deny the legitimacy of the idea about God, at least not the deist one (or pantheistic).”

“When my husband died, because he was so famous and known for not being a believer, many people would come up to me-it still sometimes happens-and ask me if Carl changed at the end and converted to a belief in an afterlife. They also frequently ask me if I think I will see him again. Carl faced his death with unflagging courage and never sought refuge in illusions. The tragedy was that we knew we would never see each other again. I don't ever expect to be reunited with Carl. But, the great thing is that when we were together, for nearly twenty years, we lived with a vivid appreciation of how brief and precious life is. We never trivialized the meaning of death by pretending it was anything other than a final parting. Every single moment that we were alive and we were together was miraculous-not miraculous in the sense of inexplicable or supernatural. We knew we were beneficiaries of chance. . . . That pure chance could be so generous and so kind. . . . That we could find each other, as Carl wrote so beautifully in Cosmos, you know, in the vastness of space and the immensity of time. . . . That we could be together for twenty years. That is something which sustains me and it’s much more meaningful. . . . The way he treated me and the way I treated him, the way we took care of each other and our family, while he lived. That is so much more important than the idea I will see him someday. I don't think I'll ever see Carl again. But I saw him. We saw each other. We found each other in the cosmos, and that was wonderful.”
