Carl Sagan Quote: “El universo no fue hecho a medida del hombre; tampoco le es hostil: es indiferente.”
Carl Sagan Quote: “I don’t know where I’m going, but I’m on my way.”
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: “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: “Skepticism does not sell well.”
Carl Sagan Quote: “On the other hand, mere critical thinking, without creative and intuitive insights, without the search for new patterns, is sterile and doomed. To solve complex problems in changing circumstances requires the activity of both cerebral hemispheres: the path to the future lies through the corpus callosum.”
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: “Science is not only compatible with spirituality; it is a profound source of spirituality. When we recognize our place in an immensity of light-years and in the passage of ages, when we grasp the intricacy, beauty, and subtlety of life, then that soaring feeling, that sense of elation and humility combined, is surely spiritual.”
Carl Sagan Quote: “La ciencia no es solamente compatible con la espiritualidad, sino que es una profunda fuente de espiritualidad.”
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: “Pseudoscience speaks to powerful emotional needs that science often leaves unfulfilled. It caters to fantasies about personal powers we lack and long for.”
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 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: “A still more glorious dawn awaits.”
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: “The lure of the marvelous blunts our critical faculties.”
Carl Sagan Quote: “God pity a one-dream man.”
Carl Sagan Quote: “The universe belongs to those who, at least to some degree, have figured it out.”
Carl Sagan Quote: “Sometimes she would be engaged in a laboratory exercise or a seminar when the instructor would say, “Gentlemen, let’s proceed,” and sensing Ellie’s frown would add, “Sorry, Miss Arroway, but I think of you as one of the boys.” The highest compliment they were capable of paying was that in their minds she was not overtly female.”
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: “No question; language can free us of feeling, or almost. Maybe that’s one of its functions – so we can understand the world without becoming entirely overwhelmed by it.”
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: “Civilization is a product of the cerebral cortex.”
Carl Sagan Quote: “In our time we have less severe standards. We tell children about Santa Claus, the Easter Bunny, and the Tooth Fairy for reasons we think emotionally sound, but then disabuse them of these myths before they’re grown. Why retract? Because their well-being as adults depends on them knowing the world as it really is. We worry, and for good reason, about adults who still believe in Santa Claus.”
Carl Sagan Quote: “A radio telescope works more like a light meter than a camera. You point it toward some fairly broad region of the sky, and it records how much energy, in a particular radio frequency, is coming down to Earth.”
Carl Sagan Quote: “The trapdoor beneath our feet swings open. We find ourselves in bottomless free fall. We are lost in a great darkness, and there’s no one to send out a search party. Given so harsh a reality, of course we’re tempted to shut our eyes and pretend that we’re safe and snug at home, that the fall is only a bad dream.”
Carl Sagan Quote: “When asked how he accomplished his astonishing discoveries, Newton replied unhelpfully, “By thinking upon them.”
Carl Sagan Quote: “And just when she felt more capable of love than she had ever been, she found herself alone.”
Carl Sagan Quote: “The Earth is a very small stage in a vast cosmic arena. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. 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.”
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 book of Nature had waited more than a millennium for a reader.”
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: “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: “But deep down, the the molecular heart of life, the trees and we are essentially identical.”
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: “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: “Thus, 99 percent of the Earth’s atmosphere is of biological origin. The sky is made by life.”
Carl Sagan Quote: “In a cosmic perspective, most human concerns seem insignificant, even petty.”
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: “One of the central issues in the world population crisis is poverty.”
Carl Sagan Quote: “The chief danger of adopting a credible pose of irrationality is that to succeed in the pretense you have to be very good. After a while, you get used to it. It becomes pretense no longer.”
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: “Faith is clearly not enough for many people. They crave hard evidence, scientific proof. They long for the scientific seal of approval, but are unwilling to put up with the rigorous standards of evidence that impart credibility to that seal. What a relief it would be: doubt reliably abolished! Then the irksome burden of looking after ourselves would be lifted. We’re worried – and for good reason – about what it means for the human future if we have only ourselves to rely upon.”
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: “Liberation from superstition is a necessary but not a sufficient condition for science.”
Carl Sagan Quote: “It is pointless to worry about the possible malevolent intentions of an advanced civilization with whom we might make contact. It is more likely that the mere fact they have survived so long means they have learned to live with themselves and others. Perhaps our fears about extraterrestrial contact are merely a projection of our own backwardness, an expression of our guilty conscience about our past history: the ravages that have been visited on civilizations only slightly more backward than we.”
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: “Broca was quoted as saying, “I would rather be a transformed ape than a degenerate son of Adam.”
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: “In manned Earth orbital flights, still other problems arise. Consider a religious Muslim or Jew circling the Earth once every ninety minutes. Is he obligated to celebrate the Sabbath every seventh orbit? Spaceflight provides access to environments very different from those in which we and our customs have grown up.”
