The universe is a pretty big place. If it's just us, seems like an awful waste of space.
Carl Sagan (Contact)
You're an interesting species. An interesting mix. You're capable of such beautiful dreams, and such horrible nightmares. You feel so lost, so cut off, so alone, only you're not. See, in all our searching, the only thing we've found that makes the emptiness bearable, is each other.
Carl Sagan (Contact)
She had studied the universe all her life, but had overlooked its clearest message: For small creatures such as we the vastness is bearable only through love.

It's hard to kill a creature once it lets you see its consciousness.

We all have a thirst for wonder. It's a deeply human quality. Science and religion are both bound up with it. What I'm saying is, you don't have to make stories up, you don't have to exaggerate. There's wonder and awe enough in the real world. Nature's a lot better at inventing wonders than we are.
Carl Sagan (Contact)
Any faith that admires truth, that strives to know God, must be brave enough to accommodate the universe.
Carl Sagan (Contact)
Your religion assumes that people are children and need a boogeyman so they'll behave. You want people to believe in God so they'll obey the law. That's the only means that occurs to you: a strict secular police force, and the threat of punishment by an all-seeing God for whatever the police overlook. You sell human beings short.

I've always thought an agnostic is an atheist without the courage of his convictions.

Perhaps the depth of love can be calibrated by the number of different selves that are actively involved in a given relationship.
Carl Sagan (Contact)
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.
Carl Sagan (Contact)
Their position seems to be that their God is so great he doesn't even have to exist.

You know the opinion of Cervantes? He said that reading a translation is like examining the back of a piece of tapestry.
Carl Sagan (Contact)
Anything you don't understand, you attribute to God. God for you is where you sweep away all the mysteries of the world, all the challenges to our intelligence. You simply turn your mind off and say God did it.

There are huge advertising budgets only when there's no difference between the products. If the products really were different, people would buy the one that's better. Advertising teaches people not to trust their judgment. Advertising teaches people to be stupid.

At the very moment that humans discovered the scale of the universe and found that their most unconstrained fancies were in fact dwarfed by the true dimensions of even the Milky Way Galaxy, they took steps that ensured that their descendants would be unable to see the stars at all. For a million years humans had grown up with a personal daily knowledge of the vault of heaven. In the last few thousand years they began building and emigrating to the cities. In the last few decades, a major fraction of the human population has abandoned a rustic way of life. As technology developed and the cities were polluted, the nights became starless. New generations grew to maturity wholly ignorant of the sky that had transfixed their ancestors and that had stimulated the modern age of science and technology. Without even noticing, just as astronomy entered a golden age most people cut themselves off from the sky, a cosmic isolationism that ended only with the dawn of space exploration.

Black holes collect problems faster than they collect matter.

But the male lexicographers had somehow neglected to coin a word for the dislike of men. They were almost entirely men themselves, she thought, and had been unable to imagine a market for such a word.
Carl Sagan (Contact)
She began to understand why lovers talk baby talk to one another. There was no other socially acceptable circumstance in which the children inside her were permitted to come out. If the one-year-old, the five-year- old, the twelve-year-old, and the twenty-year-old all find compatible personalities in the beloved, there is a real chance to keep all of these sub-personas happy. Love ends their long loneliness. Perhaps the depth of love can be calibrated by the number of different selves that are actively involved in a given relationship.

What if, despite all our pretense and disguise, it was necessary to appear in public with the person we loved most of all? Imagine this a prerequisite for social discourse on Earth.
Carl Sagan (Contact)
The major religions on the Earth contradict each other left and right. You can't all be correct. And what if all of you are wrong? It's a possibility, you know. You must care about the truth, right? Well, the way to winnow through all the differing contentions is to be skeptical. I'm not any more skeptical about your religious beliefs than I am about every new scientific idea I hear about. But in my line of work, they're called hypotheses, not inspiration and not revelation.
Carl Sagan (Contact)
...You think if I haven't had your religious experience I can't appreciate the magnificence of your god. But it's just the opposite. I listen to you, and I think, his god is too small! One paltry planet, a few thousand years -- hardly worth the attention of a minor deity, much less the Creator of the universe.

She had to fight against developing too combative a personality or becoming altogether a misanthrope. She suddenly caught herself. "Misanthrope" is someone who dislikes everybody, not just men. And they certainly had a word for someone who hates women: "misogynist." But the male lexicographers had somehow neglected to coin a word for the dislike of men. They were almost entirely men themselves, she thought, and had been unable to imagine a market for such a word.

Spaceflight, therefore, is subversive. If they are fortunate enough to find themselves in orbit, most people, after a little meditation, have similar thoughts. The nations that had instituted spaceflight had done so largely for nationalistic reasons; it was a small irony that almost everyone who entered space received a startling glimpse of a transnational perspective, of the Earth as one world.

Everything not forbidden by the laws of nature, he assured her - quoting a colleague down the hall - is mandatory.
Carl Sagan (Contact)
The chance of receiving a signal from a civilization exactly as advanced as we are should be minuscule. If they were even a little behind us, they would lack the technological capability to communicate with us at all. So the most likely signal would come from a civilization much more advanced.
Carl Sagan (Contact)
What worries me the most,' she continued, 'is the opposite, the possibility that they're not trying. They could communicate with us, all right, but they're not doing it because they don't see any point to it. It's like..."--she glanced down at the edge of the tablecloth they had spread over the grass--"like the ants. They occupy the same landscape that we do. They have plenty to do, things to occupy themselves. On some level they're very well aware of their environment. But we don't try to communicate with them. So I don't think they have the foggiest notion that we exist.

What was an infant's view of air travel? You go to a special place, walk into a large room with seats in it, and sit down. The room rumbles and shakes for four hours. Then you get up and walk off. Magically, you're somewhere else. The means of transportation seems obscure to you, but the basic idea is easy to grasp, and precocious mastery of the Navier-Stokes equations is not required.

In Mozambique, the story goes, monkeys do not talk, because they know if they utter even a single word some man will come and put them to work.

She had spent her career attempting to make contact with the most remote and alien of strangers, while in her own life she had made contact with hardly anyone at all.

Carl Sagan (Contact)
Occasionally, I get a letter from someone who is in “contact” with extraterrestrials. I am invited to “ask them anything.” And so over the years I’ve prepared a little list of questions. The extraterrestrials are very advanced, remember. So I ask things like, “Please provide a short proof of Fermat’s Last Theorem.” Or the Goldbach Conjecture. And then I have to explain what these are, because extraterrestrials will not call it Fermat’s Last Theorem. So I write out the simple equation with the exponents. I never get an answer. On the other hand, if I ask something like “Should we be good?” I almost always get an answer.

You've tapped yourself in some sort of fifth­century religious mania. Since then the Renaissance has happened, the Enlightenment has happened. Where've you been?
Carl Sagan (Contact)
Our television signals leave this planet and go out into space...the signals spread out from the earth in spherical waves, a little like ripples in a pond. They travel at the speed of light, 186,000 miles a second, and essentially go on forever. The better some other civilizations receivers are, the farther away they could be and still pick up our tv signals. Even we could detect a strong tv transmission from a planet going around the nearest star.' President: 'You mean everything? You mean to say all that crap on television - the car crashes, wrestling, the porno channels, the evening news?

There were human cultures that taught an afterlife of the blessed on mountaintops or in clouds in caverns or oases but she could not recall any in which if you were very very good when you died you went to the beach.

She was determined to be as tough-minded as possible, without abandoning the sense of wonder that was driving her in the first place.

When I say I’m an agnostic, I only mean that the evidence isn’t in. There isn’t compelling evidence that God exists—at least your kind of god—and there isn’t compelling evidence that he doesn’t.

Ever been in love?' The question was direct, matter-of-fact. 'Halfway, half a dozen times. But'—she glanced at the nearest telescope—"there was always so much noise, the signal was hard to find.
Carl Sagan (Contact)
She came to admire him so much that his love for her affected her own self-esteem: She liked herself better because of him. And since he clearly felt the same, there was a kind of infinite regress of love and respect underlying their relationship. At least, that was how she described it to herself. In the presence of so many of her friends, she had felt an undercurrent of loneliness.

The others would then fall silent and she would continue about doped gallium arsenide detectors, or the ethanol content of the galactic cloud W-3. The quantity of 200-proof alcohol in this single interstellar cloud was more than enough to maintain the present population of the Earth, if every adult were a dedicated alcoholic, for the age of the solar system. The tamada had appreciated the remark.

Religious sects, established and marginal, and some newly invented for the purpose, were dissecting the theological implications of the Message. Some thought it was from God, and some from the Devil. Astonishingly, some were even unsure.

The Earth was in darkness except for a patchwork and sprinkle of light, the plucky attempt of humans to compensate for the opacity of the Earth when their hemisphere was averted from the Sun.

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.

I say you don't need any more proof. There are proofs enough already. Cygnus A and all that are just for the scientists. You think it'll be hard to convince ordinary people that you're telling the truth. I think it'll be easy as pie. You think your story is too peculiar, too alien. But I've heard it before. I know it well. And I bet you do too.

But there was also a notable decline in many quarters of the world of jingoist rhetoric and puerile self-congratulatory nationalism. There was a sense of the human species, billions of tiny beings spread over the world, collectively presented with an unprecedented opportunity, or even a grave common danger. To many, it seemed absurd for the contending nation states to continue their deadly quarrels when faced with a nonhuman civilization of vastly greater capabilities. There was a whiff of hope in the air.

It suddenly struck her what a humiliation she would feel for the human species if in the end they failed to understand the Message.

Are the worlds of more advanced civilizations totally geometrized, entirely rebuilt by their inhabitants? Or would the signature of really advanced civilization be that they left no sign at all?

There were excesses in science and there were excesses in religion. A reasonable man wouldn’t be stampeded by either one. There were many interpretations of Scripture and many interpretations of the natural world. Both were created by God, so both must be mutually consistent. Wherever a discrepancy seems to exist, either a scientist or a theologian—maybe both—hasn’t been doing his job. Palmer

Some women, it seemed, were entirely without guile and bestowed their affections with hardly a moment's conscious thought. Others set out to implement a campaign of military thoroughness, with branched contingency trees and fallback positions, all to 'catch' a desirable man. The word 'desirable' was the giveaway, she thought. The poor jerk wasn't actually desired, only 'desirable' - a plausible object of desire in the opinion of those others on whose account this whole sorry charade was performed. Most women, she thought, were somewhere in the middle, seeking to reconcile their passions with their perceived long-term advantage.

She was a wonder junkie. In her mind, she was a hill tribesman standing slack-jawed before the real Ishtar Gate of ancient Babylon; Dorothy catching her first glimpse of the vaulted spires of the Emerald City of Oz; a small boy from darkest Brooklyn plunked down in the Corridor of Nations of the 1939 World’s Fair, the Trylon and Perisphere beckoning in the distance; she was Pocahontas sailing up the Thames estuary with London spread out before her from horizon to horizon. been voyaging between the stars when the ancestors of humans were still brachiating from branch to branch in the dappled sunlight of the forest canopy. Drumlin, like many others she had known over the years, had called her an incurable romantic; and she found herself wondering again why so many people thought it some embarrassing disability. Her romanticism had been a driving force in her life and a fount of delights. Advocate and practitioner of romance, she was off to see the Wizard.

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.

The ancient Aztec and the ancient Greek words for “God” are nearly the same. Is this evidence of some contact or commonality between the two civilizations, or should we expect occasional such coincidences between two wholly unrelated languages merely by chance? Or could, as Plato thought in the Cratylus, certain words be built into us from birth?

Socrates described his philosophical inspiration as the work of a personal, benign demon. His teacher, Diotima of Mantineia, tells him (in Plato’s Symposium) that “Everything demonic is intermediate between God and mortal. God has no contact with man,” she continues; “only through the demonic is there intercourse and conversation between man and gods, whether in the waking state or during sleep.

Any faith that admires truth, that strives to know God, must be brave enough to accommodate the universe. I mean the real universe. All those light-years. All those worlds. I think of the scope of your universe, the opportunities it affords the Creator, and it takes my breath away. It’s much better than bottling Him up in one small world. I never liked the idea of Earth as God’s green footstool. It was too reassuring, like a children’s story...like a tranquilizer. But your universe has room enough, and time enough, for the kind of God I believe in.

You'd be surprised how rarely something like that happens. In the long run, the aggressive civilizations destroy themselves, almost always. It's their nature. They can't help it.

Once, during a vigorous discussion on the relative merits of the two political systems, Ellie had boasted that she had been free to march in front of the White House protesting American involvement in the Vietnam War.

Since the transmitting civilization was clearly more advanced than ours, and because it clearly - at least as of twenty-six years ago - had not destroyed itself, it followed, some argued, that technological civilizations did not inevitably self-destruct. In a world gingerly experimenting with major divestitures of nuclear weapons and their delivery systems, the Message was taken by whole populations as a reason for hope. Many considered the Message the best news in a long time. For decades, young people had tried not to think too carefully about tomorrow. Now, there might be a benign future after all.

She could imagine problems enormously beyond us that would be old hat to them. But she couldn't get into their minds; she couldn't imagine what thinking would be like if you were much more capable than a human being. Of course. No surprise. What did she expect? It was like trying to visualize a new primary color or a world in which you could recognize several hundred acquaintances individually only be their smells... She could talk about this, but she couldn't experience it. By definition, it has to be mighty hard to understand the behavior of a being much smarter than you are. But even so, even so: Why only prime numbers?

Above the table on which the chattering telefax set was a mirror. In it she saw a woman neither young nor old, neither mother nor daughter. They had been right to keep the truth from her. She was not sufficiently advanced to receive that signal, much less decrypt it. She had spent her career attempting to make contact with the most remote and alien of strangers, while in her own life she had made contact with hardly anyone at all. She had been fierce in debunking the creation myths of others, and oblivious to the lie at the core of her own. She had studied the universe all her life, but had overlooked its clearest message: For small creatures such as we the vastness is bearable only through love.

When Geppetto is just finishing the construction of Pinocchio, he turns his back on the puppet and is promptly sent flying by a well-placed kick. At that instant the carpenter's friend arrives and asks him what he is doing sprawled on the floor. 'I am teaching', Geppetto replies with dignity, 'the alphabet to the ants.' This seemed to Ellie extremely witty, and she delighted in recounteing it to her friends. But each time she quoted it there was an unspoked question lingering at the edge of her consciousness: Could you teach the alphabet to the ants? And would you want to? Down there with hundreds of scurrying insects who might crawl all over your skin, or even sting you? What could ants know, anyway?

En el mismo momento en que el hombre descubrió la vastedad del universo y se dio cuenta de que aun sus más disparatadas fantasías eran ínfimas comparadas con la verdadera dimensión de la Vía Láctea, tomó medidas para asegurar que sus descendientes no pudiesen ver las estrellas en lo más mínimo. Durante un millón de años, los humanos se han criado en el contacto diario, personal, con la bóveda celeste. En los últimos milenios comenzaron a construir las ciudades y a emigrar hacia ellas. En el curso de las últimas décadas, gran parte de la población humana abandonó una forma rústica de vida. A medida que avanzaba la tecnología y se contaminaban los centros urbanos, las noches se fueron quedando sin estrellas. Nuevas generaciones alcanzaron la madurez ignorando totalmente el firmamento que había pasmado a sus mayores y estimulado el advenimiento de la era moderna de la ciencia y la tecnología. Sin darse cuenta siquiera, justo cuando la astronomía entraba en su edad de oro, la mayoría de la gente se apartaba del cielo en un aislamiento cósmico que sólo terminó con los albores de la exploración espacial.

(Notably, temporary loss of blood or oxygen or excess carbon dioxide in the blood can also cause a disruption in the temporoparietal region and induce out-of-body experiences, which may explain the prevalence of these sensations during accidents, emergencies, heart attacks, etc.) NEAR-DEATH EXPERIENCES But perhaps the most dramatic category of out-of-body experiences are the near-death stories of individuals who have been declared dead but then mysteriously regained consciousness. In fact, 6 to 12 percent of survivors of cardiac arrest report having near-death experiences. It’s as though they have cheated death itself. When interviewed, they have dramatic tales of the same experience: they left their body and drifted toward a bright light at the end of a long tunnel. The media have seized upon this, with numerous best sellers and TV documentaries devoted to these theatrical stories. Many bizarre theories have been proposed to explain near-death experiences. In a poll of two thousand people, fully 42 percent believed that near-death experiences were proof of contact with the spiritual world that lies beyond death. (Some believe that the body releases endorphins—natural narcotics—before death. This may explain the euphoria that people feel, but not the tunnel and the bright lights.) Carl Sagan even speculated that near-death experiences were a reliving of the trauma of birth. The fact that these individuals recount very similar experiences doesn’t necessarily corroborate their glimpses into the afterlife; in fact, it seems to indicate that there is some deep neurological event happening. Neurologists have looked into this phenomenon seriously and suspect that the key may be the decrease of blood flow to the brain that often accompanies near-death cases, and which also occurs in fainting. Dr. Thomas Lempert, a neurologist at the Castle Park Clinic in Berlin, conducted a series of experiments on forty-two healthy individuals, causing them to faint under controlled laboratory conditions. Sixty percent of them had visual hallucinations (e.g., bright lights and colored patches). Forty-seven percent of them felt that they were entering another world. Twenty percent claimed to have encountered a supernatural being. Seventeen percent saw a bright light. Eight percent saw a tunnel. So fainting can mimic all the sensations people have in near-death experiences
