Carl Sagan Quote: “Think of the rivers of blood, spilled by all those generals and emperors, so that in glory and triumph, they could become the momentary masters, of a fraction of a dot... our posturings, our imagined self-importance, the delusion that we have some privileged position in the universe – are challenged by that point of pale light.”
Carl Sagan Quote: “To live in the hearts we leave behind is to live forever.”
Carl Sagan Quote: “The Man in the Moon is in fact a record of ancient catastrophes – most of which took place before humans, before mammals, and probably even before life arose on Earth. It is a characteristic conceit of our species to put a human face on random cosmic violence.”
Carl Sagan Quote: “A universe that is unknowable is no fit place for a thinking being. The ideal universe for us is one very much like the universe we inhabit.”
Carl Sagan Quote: “I believe in Spinoza’s God, who revealed himself in the harmony of all being, not in the God who concerns himself with the fate and actions of men” – a more subtle religious view embraced by.”
Carl Sagan Quote: “We knew the Moon from our earliest days. It was there when our ancestors descended from the trees into the savannahs, when we learned to walk upright, when we first devised stone tools, when we domesticated fire, when we invented agriculture and built cities and set out to subdue the Earth.”
Carl Sagan Quote: “On the scale of worlds – to say nothing of stars or galaxies – humans are inconsequential, a thin film of life on an obscure and solitary lump of rock and metal.”
Carl Sagan Quote: “But deep down, the the molecular heart of life, the trees and we are essentially identical.”
Carl Sagan Quote: “If it takes a little myth and ritual to get us through a night that seems endless, who among us cannot sympathize and understand?”
Carl Sagan Quote: “It is on this world that we developed our passion for exploring the Cosmos, and it is here that we are, in some pain and with no guarantees, working out our destiny.”
Carl Sagan Quote: “A survey shows that more college graduates are homosexual than those with lesser education; therefore education makes people gay.”
Carl Sagan Quote: “Mars has become a kind of mythic arena onto which we have projected our earthly hopes and fears. But our psychological predispositions pro or con must not mislead us. All that matters is the evidence, and the evidence is not yet in.”
Carl Sagan Quote: “Except for hydrogen, all the atoms that make each of us up – the iron in our blood, the calcium in our bones, the carbon in our brains – were manufactured in red giant stars thousands of light-years away in space and billions of years ago in time. We are, as I like to say, starstuff.”
Carl Sagan Quote: “Science is an ongoing process. It never ends. There is no single ultimate truth to be achieved, after which all the scientists can retire. And because this is so, the world is far more interesting, both for the scientists and for the millions of people in every nation who, while not professional scientists, are deeply interested in the methods and findings of science.”
Carl Sagan Quote: “We have examined the universe in space and seen that we live on a mote of dust circling a humdrum star in the remotest corner of an obscure galaxy.”
Carl Sagan Quote: “Our species has discovered a way to communicate through the dark, to transcend immense distances. No means of communication is faster or cheaper or reaches out farther. It’s called radio.”
Carl Sagan Quote: “When asked how he accomplished his astonishing discoveries, Newton replied unhelpfully, “By thinking upon them.”
Carl Sagan Quote: “For all its material advantages, the sedentary life has left us edgy, unfulfilled. Even after 400 generations in villages and cities, we haven’t forgotten. The open road still softly calls, like a nearly forgotten song of childhood. We invest far-off places with a certain romance. This appeal, I suspect, has been meticulously crafted by natural selection as an essential element in our survival.”
Carl Sagan Quote: “The wolf stands on its hind legs, places its forelegs on the scientist’s shoulders, and places its jaws around the scientist’s head. This is just the wolf’s way of being friendly. If you’re an animal who doesn’t know how to talk, a very clear signal is communicated: “See my teeth? Feel them? I could hurt you, I really could. But I won’t. I like you.”
Carl Sagan Quote: “Even after 400 generations in villages and cities, we haven’t forgotten. The open road still softly calls, like a nearly forgotten song of childhood.”
Carl Sagan Quote: “Hallucinations may be a neglected low door in the wall to a scientific understanding of the sacred.”
Carl Sagan Quote: “We will know which stars to visit. Our descendants will then skim the light years, the children of Thales and Aristarchus, Leonardo and Einstein.”
Carl Sagan Quote: “Nearly everyone in ancient Egypt exhorted the gods to let the Pharaoh live ’forever. These collective prayers failed. Their failure constitutes data.”
Carl Sagan Quote: “Billions of years from now our sun, then a distended red giant star, will have reduced Earth to a charred cinder. But the Voyager record will still be largely intact, in some other remote region of the Milky Way galaxy, preserving a murmur of an ancient civilization that once flourished – perhaps before moving on to greater deeds and other worlds – on the distant planet Earth.”
Carl Sagan Quote: “Adolf Hitler! Ken, it makes me furious. Forty million people die to defeat that megalomaniac, and he’s the star of the first broadcast to another civilization? He’s representing us. And them. It’s that madman’s dream come true.”
Carl Sagan Quote: “600 million years ago, the monopolizing grip of the algae was broken and an enormous proliferation of new lifeforms emerged, an event called the Cambrian explosion. Life had arisen almost immediately after the origin of the Earth, which suggests that life may be an inevitable chemical process on an Earth-like planet.”
Carl Sagan Quote: “Lashley also reported no apparent change in the general behavior of a rat when significant fractions – say 10 percent – of its brain were removed. But no one asked the rat of its opinion.”
Carl Sagan Quote: “The Sphinx is missing a nose. Someone shot it off in a moment of idle desecration – some say it was Mameluke Turks, others, Napoleonic soldiers.”
Carl Sagan Quote: “The scientific way of thinking is at once imaginative and disciplined. This is central to its success. Science invites us to let the facts in, even when they don’t conform to our preconceptions. It counsels us to carry alternative hypotheses in our heads and see which best fit the facts. It urges on us a delicate balance between no-holds-barred openness to new ideas, however heretical, and the most rigorous skeptical scrutiny of everything – new ideas and established wisdom.”
Carl Sagan Quote: “Society corrupts the best of us. It is a little unfair, I think, to criticize a person for not sharing the enlightenment of a later epoch, but it is also profoundly saddening that such prejudices were so extremely pervasive. The question raises nagging uncertainties about which of the conventional truths of our own age will be considered unforgivable bigotry by the next.”
Carl Sagan Quote: “We’ve arranged a civilization in which most crucial elements profoundly depend on science and technology. We have also arranged things so that almost no one understands science and technology. This is a prescription for disaster.”
Carl Sagan Quote: “This process is called artificial selection. In the case of the Heike crab it was effected more or less unconsciously by the fishermen, and certainly without any serious contemplation by the crabs. But humans have deliberately selected which plants and animals shall live and which shall die for thousands of years.”
Carl Sagan Quote: “The level of public education in science and technology is an important sign of the national scientific accomplishment. It is a matter of overall importance in economic development, scientific advance, and the progress of society.”
Carl Sagan Quote: “The universe belongs to those who, at least to some degree, have figured it out.”
Carl Sagan Quote: “Placebos can be astonishingly effective, especially for colds, anxiety, depression, pain, and symptoms that are plausibly generated by the mind. Conceivably, endorphins – the small brain proteins with morphinelike effects – can be elicited by belief. A placebo works only if the patient believes it’s an effective medicine. Within strict limits, hope, it seems, can be transformed into biochemistry. As.”
Carl Sagan Quote: “The more we want it to be true, the more careful we have to be. No witness’s say-so is good enough. People make mistakes. People play practical jokes. People stretch the truth for money or attention or fame. People occasionally misunderstand what they’re seeing. People sometimes even see things that aren’t there.”
Carl Sagan Quote: “The Cosmos is rich beyond measure – in elegant facts, in exquisite interrelationships, in the subtle machinery of awe.”
Carl Sagan Quote: “The only planet we are sure is inhabited is a tiny speck of rock and metal, shining feebly by reflected sunlight, and at this distance utterly lost.”
Carl Sagan Quote: “I think the discomfort that some people feel in going to the monkey cages at the zoo is a warning sign.”
Carl Sagan Quote: “Then, if we really want our celestial neighbors to know how far we have progressed intelectually, we should have included pictures of Santa Claus, the Easter Bunny and the Tooth Fairy.”
Carl Sagan Quote: “If it were widely understood that claims to knowledge require adequate evidence before they can be accepted, there would be no room for pseudoscience.”
Carl Sagan Quote: “The whole idea of a democratic application of skepticism is that everyone should have the essential tools to effectively and constructively evaluate claims to knowledge.”
Carl Sagan Quote: “By far the most exciting, satisfying and exhilarating time to be alive is the time in which we pass from ignorance to knowledge on these fundamental issues; the age where we begin in wonder and end in understanding. In all of the four-billion-year history of life on our planet, in all of the four-million-year history of the human family, there is only one generation privileged to live through that unique transitional moment: that generation is ours.”
Carl Sagan Quote: “God pity a one-dream man.”
Carl Sagan Quote: “Many of the problems facing us may be soluble, but only if we are willing to embrace brilliant, daring and complex solutions. Such solutions require brilliant, daring and complex people. I believe that there are many more of them around – in every nation, ethnic group and degree of affluence – than we realize.”
Carl Sagan Quote: “One of the reasons for its success is that science has built-in, error-correcting machinery at its very heart. Some may consider this an overbroad characterization, but to me every time we exercise self-criticism, every time we test our ideas against the outside world, we are doing science. When we are self-indulgent and uncritical, when we confuse hopes and facts, we slide into pseudoscience and superstition. Every.”
Carl Sagan Quote: “The surface of the Earth is the shore of the cosmic ocean. From it we have learned most of what we know. Recently, we have waded a little out to sea, enough to dampen our toes or, at most, wet our ankles. The water seems inviting. The ocean calls. Some part of our being knows this is from where we came. We long to return. These aspirations are not, I think, irreverent, although they may trouble whatever gods may be.”
Carl Sagan Quote: “The cerebral cortex is a liberation. We need no longer be trapped in the genetically inherited behavior patterns of lizards and baboons. We are, each of us, largely responsible for what gets put into our brains, for what, as adults, we wind up caring for and knowing about. No longer at the mercy of the reptile brain, we can change ourselves.”
Carl Sagan Quote: “The Cosmos is all that is or was or ever will be. Our feeblest contemplations of the Cosmos stir us – there is a tingling in the spine, a catch in the voice, a faint sensation, as if a distant memory, of falling from a height. We know we are approaching the greatest of mysteries.”
Carl Sagan Quote: “And just when she felt more capable of love than she had ever been, she found herself alone.”
