Famous Carl Sagan Quotes

“El mundo es totalmente diferente si la máxima velocidad de un mensaje es la que pueden alcanzar un caballo o una carabea, o bien la de la luz. La velocidad de la luz significa que podemos hablar - prácticamente a tiempo real- con cualquier persona de la Tierra o incluso de la Luna. Pensemos en la medicina. Hace unos siglos, la mayoría de los niños nacidos en las grandes familias de Europa morían en la infancia, a pesar de contar con la mejor asistencia médica de su época. Hoy en día, incluso los pobres de algunas naciones tienen una mortalidad infantil asombrosamente inferior a la de las cabezas coronadas del siglo XVII. O pensemos en la disponibilidad de medios seguros y baratos de control de la natalidad, que implica una revolución en las relaciones humanas y, sobre todo, en la condición de las mujeres.”

“Si queremos que el mundo escape de las temibles consecuencias del crecimiento de la población global y de los diez mil o doce mil millones de personas en el planeta a finales del siglo XXI, debemos inventar medios seguros y más eficientes de cultivar alimentos, con el consiguiente abastecimiento de semillas, riego, fertilizantes, pesticidas, sistemas de transporte y refrigeración. También se necesitarán métodos contraconceptivos ampliamente disponibles y aceptables, pasos significativos hacia la igualdad política de las mujeres y mejoras en las condiciones de vida de los más pobres.”

“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. So are our emotions in the presence of great art or music or literature, or acts of exemplary selfless courage such as those of Mohandas Gandhi or Martin Luther King, Jr. The notion that science and spirituality are somehow mutually exclusive does a disservice to both.”

“In its encounter with Nature, science invariably elicits a sense of reverence and awe. The very act of understanding is a celebration of joining, merging, even if on a very modest scale, with the magnificence of the Cosmos. And the cumulative worldwide build-up of knowledge over time converts science into something only a little short of a trans-national, trans-generational meta-mind.”

“For their surface area, insects weigh very little. A beetle, falling from a high altitude, quickly achieves terminal velocity: air resistance prevents it from falling very fast, and, after alighting on the ground, it will walk away, apparently none the worse for the experience… In contrast, human beings are characteristically maimed or killed by any fall of more than a few dozen feet: because of our size, we weigh too much for our surface area.”

“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. Long summers, mild winters, rich harvests, plentiful game—none of them lasts forever. It is beyond our powers to predict the future. Catastrophic events have a way of sneaking up on us, of catching us unaware. Your own life, or your band’s, or even your species’ might be owed to a restless few—drawn, by a craving they can hardly articulate or understand, to undiscovered lands and new worlds. Herman Melville, in Moby Dick, spoke for wanderers in all epochs and meridians: “I am tormented with an everlasting itch for things remote. I love to sail forbidden seas…” Maybe it’s a little early. Maybe the time is not quite yet. But those other worlds— promising untold opportunities—beckon. Silently, they orbit the Sun, waiting.”

“You see, the religious people — most of them — really think this planet is an experiment. That's what their beliefs come down to. Some god or other is always fixing and poking, messing around with tradesmen's wives, giving tablets on mountains, commanding you to mutilate your children, telling people what words they can say and what words they can't say, making people feel guilty about enjoying themselves, and like that. Why can't the gods leave well enough alone? All this intervention speaks of incompetence. If God didn't want Lot's wife to look back, why didn't he make her obedient, so she'd do what her husband told her? Or if he hadn't made Lot such a shithead, maybe she would've listened to him more. If God is omnipotent and omniscient, why didn't he start the universe out in the first place so it would come out the way he wants? Why's he constantly repairing and complaining? No, there's one thing the Bible makes clear: The biblical God is a sloppy manufacturer. He's not good at design, he's not good at execution. He'd be out of business if there was any competition.”

“Every aspect of Nature reveals a deep mystery and touches our sense of wonder and awe. Those afraid of the universe as it really is, those who pretend to nonexistent knowledge and envision a Cosmos centered on human beings will prefer the fleeting comforts of superstition. They avoid rather than confront the world. But those with the courage to explore the weave and structure of the Cosmos, even where it differs profoundly from their wishes and prejudices, will penetrate its deepest mysteries.”

“I would love to believe that when I die I will live again, that some thinking, feeling, remembering part of me will continue. But much as I want to believe that, and despite the ancient and worldwide cultural traditions that assert an afterlife, I know of nothing to suggest that it is more than wishful thinking. The world is so exquisite with so much love and moral depth, that there is no reason to deceive ourselves with pretty stories for which there's little good evidence. Far better it seems to me, in our vulnerability, is to look death in the eye and to be grateful every day for the brief but magnificent opportunity that life provides.”

'cause it's witchcraft, wicked witchcraft And although I know it's strictly taboo When you arouse the need in me My heart says "Yes, indeed" in me "Proceed with what you're leadin' me to" It's such an ancient pitch But one I wouldn't switch 'cause there's no nicer witch than you [instrumental] 'cause it's witchcraft, that crazy witchcraft And although I know it's strictly taboo When you arouse the need in me My heart says "Yes, indeed" in me "Proceed with what you're leadin' me to" It's such an ancient pitch But one I'd never switch 'cause there's no nicer witch than you”

“Dicho de otro modo, cualquier predisposición a la creencia religiosa puede verse poderosamente influida por la cultura indígena, viva uno donde viva. Especialmente si los niños están expuestos desde muy pequeños a una serie concreta de doctrinas, música, arte y ritual, es algo tan natural para ellos como respirar, motivo por el cual las religiones hacen tantos esfuerzos para atraer a los más jóvenes.”

“That writing as careless as Däniken's, whose principal thesis is that our ancestors were dummies, should be so popular is a sober commentary on the credulousness and despair of our times. I also hope for the continuing popularity of books like Chariots of the Gods? in high school and college logic courses, as object lessons in sloppy thinking. I know of no recent books so riddled with logical and factual errors as the works of Däniken.”

“Una científica compañera mía me contaba un reciente viaje que realizó a la meseta de Nueva Guinea, donde visitó una tribu todavía en la edad de piedra que apenas había tenido contactos con la civilización. Ignoraban lo que son los relojes de pulsera, las bebidas refrescantes y los alimentos congelados. Pero conocían el Apolo 11. Sabían que los humanos han pisado la Luna.”

“Coal, oil and gas are called fossil fuels, because they are mostly made of the fossil remains of beings from long ago. The chemical energy within them is a kind of stored sunlight originally accumulated by ancient plants. Our civilization runs by burning the remains of humble creatures who inhabited the Earth hundreds of millions of years before the first humans came on the scene. Like some ghastly cannibal cult, we subsist on the dead bodies of our ancestors and distant relatives.”

“What an astonishing thing a book is. It's a flat object made from a tree with flexible parts on which are imprinted lots of funny dark squiggles. But one glance at it and you're inside the mind of another person, maybe somebody dead for thousands of years. Across the millennia, an author is speaking clearly and silently inside your head, directly to you. Writing is perhaps the greatest of human inventions, binding together people who never knew each other, citizens of distant epochs. Books break the shackles of time. A book is proof that humans are capable of working magic." [Cosmos, Part 11: The Persistence of Memory (1980)]”

“Cuando los hombres descubren algo nuevo sienten una inclinación natural a hacer uso de ello, probablemente en respuesta a sus circuitos cerebrales. Esa extraña proclividad, que no comparten de modo sistemático las demás bestias o plantas de la Tierra, constituye tanto una causa principal del éxito humano como un motivo básico de que estemos despojando una parte tan considerable de la superficie terráquea. Las aves saben, mejor que los humanos, que no deben ensuciar su nido.”

“I find these comparisons particularly poignant: life versus death, hope versus fear. Space exploration and the highly mechanized destruction of people use similar technology and manufacturers, and similar human qualities of organization and daring. Can we not make the transition from automated aerospace killing to automated aerospace exploration of the solar system in which we live?”

“If we are willing to contemplate nuclear war and the wholesale destruction of our emerging global society, should we not also be willing to contemplate a wholesale restructuring of our societies? From an extraterrestrial perspective, our global civilization is clearly on the edge of failure in the most important task it faces: to preserve the lives and well-being of the citizens of the planet. Should we not then be willing to explore vigorously, in every nation, major changes in the traditional ways of doing things, a fundamental redesign of economic, political, social and religious institutions? Faced with so disquieting an alternative, we are always tempted to minimize the seriousness of the problem, to argue that those who worry about doomsday’s are alarmists; to hold that fundamental changes in our institutions are impractical or contrary to ‘human nature’, as if nuclear war were practical, or as if there were only one human nature. Full-scale nuclear war has never happened. Somehow this is taken to imply that it never will. But we can experience it only once. But then it will be too late to reformulate the statistics.”

“The laws of nature cannot be randomly reshuffled at the cusps [of an oscillating universe]. If the universe has already gone through many oscillations, many possible laws of gravity would have been so weak that, for any given initial expansion, the universe would not have held together. Once the universe stumbles upon such a gravitational law, it flies apart and has no further opportunity to experience another oscillation and another cusp and another set of laws of nature. Thus we can deduce from the fact that the universe exists either a finite age, or a severe restriction on the kinds of laws of nature permitted in each oscillation. If the laws of physics are not randomly reshuffled at the cusps, there must be a regularity, a set of rules, that determines which laws are permissible and which are not. Such a set of rules would comprise a new physics standing over the existing physics. Our language is impoverished; there seems to be no suitable name for such a new physics. Both 'paraphysics' and 'metaphysics' have been preempted by other rather different and, quite possibly, wholly irrelevant activities. Perhaps 'transphysics' would do.”

“En el polo opuesto de la discusión, la frase -derecho a la vida- constituye un ejemplo claro de expresión altisonante concebida para impresionar más que para aclarar las cosas. Ni hoy ni nunca ha existido en ningún país de la tierra el derecho a la vida. Criamos animales domésticos para luego darles muerte, destruimos los bosques, contaminamos ríos y lagos hasta causar la muerte de toda la fauna piscícola, cazamos venados por deporte, leopardos por la piel y ballenas para preparar comida para los perros, atrapamos a los delfines, boqueantes y semiasfixiados, con grandes redes del tipo utilizado para la pesca del atún, y senteciamos a muerte a los perros cachorros para -equilibrar la población-. Todos estos animales y vegetales están tan vivos como nosotros. Lo que muchas sociedades humanas protegen no es la vida, sino la vida el hombre, y aún así desencadenamos guerras con medios -modernos- que causan estragos a la población civil y que suponen un tributo tan escandaloso que muchos de nosotros ni siquiera nos atrevemos a entrar en su consideración.”

“What do you do when you are faced with several different gods each claiming the same territory? The Babylonian Marduk and the Greek Zeus was each considered master of the sky and king of gods. You might also decide, since they had quite different attributes, that one of them was merely invented by the priests. But if one, why not both? And so it was that the great idea arose, the realization that there might be a way to know the world without the god hypothesis; that there might be principles, forces, laws of nature, through which the world could be understood without attributing the fall of every sparrow to the direct intervention of Zeus.”

“Hay un geocentrismo práctico en nuestra vida diaria. Todavía hablamos del Sol que sale y se pone, en lugar de hablar de una Tierra que gira. Todavía pensamos en un universo organizado para nuestro beneficio y poblado tan sólo por nosotros. La exploración del espacio, en este sentido, nos hará ser un poco más humildes.”

“Desde los inicios de la civilización, en las sociedades ha habido clases privilegiadas. Unos grupos oprimen a otros y procuran mantener estas jerarquías de poder.
