Those mothers with hereditary large pelvises were able to bear large-brained babies who because of their superior intelligence were able to compete successfully in adulthood with the smaller-brained offspring of mothers with smaller pelvises.

Carl Sagan

O friend, for the morrow let us not worryThis moment we have now, let us not hurryWhen our time comes, we shall not tarryWith seven thousand-year-olds, our burden carry

Omar Khayyám

If there was one overriding element to Faraday's character, it was humility. His 'conviction of deficiency,' as he called it, stemmed in part from his deep religiosity and affected practically every facet of his life. Thus Faraday approached both his science and his everyday conduct unhampered by ego, envy, or negative emotion. In his work, he assumed the inevitability of error and failure; whenever possible, he harnessed these as guides toward further investigation. Faraday adhered to no particular school of scientific thought. Nor did he flinch when a favored hypothesis fell to the rigors of experiment.

Alan W. Hirshfeld

Whatever the reason we first mustered the _Apollo_ program, however mired it was in Cold War nationalism and the instruments of death, the inescapable recognition of the unity and fragility of the Earth is its clear and luminous dividend, the unexpected final gift of _Apollo_. What began in deadly competition has helped us to see that global cooperation is the essential precondition for our survival.Travel is broadening. It's time to hit the road again.

Carl Sagan

Would not a rational society spend more on understanding and preventing, than on preparing for, the next war?

Carl Sagan

doctors & druggists wash each other's hands

Geoffrey Chaucer

A book is made from a tree. It is an assemblage of flat, flexible parts (still called "leaves") imprinted with dark pigmented squiggles. One glance at it and you hear the voice of another person, perhaps someone dead for thousands of years. Across the millennia, the author is speaking, clearly and silently, inside your head, directly to you. Writing is perhaps the greatest of human inventions, binding together people, citizens of distant epochs, who never knew one another. Books break the shackles of time ― proof that humans can work magic.

Carl Sagan

Claims that cannot be tested, assertions immune to disproof are veridically worthless, whatever value the may have in inspiring us or in exciting our sense of wonder.

Carl Sagan

There is another connection between infancy and dreams: both are followed by amnesia. When we emerge from either state, we have great difficulty remembering what we have experienced. In both cases, I would suggest, the left hemisphere of the neocortex, which is responsible for analyticrecollection, has been functioning ineffectively.

Carl Sagan

at least some paleontologists believe that the demiseof the dinosaurs was accelerated by nocturnal predation on reptilian eggs by the early mammals. Two chicken eggs for breakfast may be all-at least on the surface-that is left of this ancient mammalian cuisine.

Carl Sagan

I have been in my bed for five weeks, oppressed with weakness and other infirmities from which my age, seventy four years, permits me not to hope release. Added to this (proh dolor! [O misery!]) the sight of my right eye — that eye whose labors (dare I say it) have had such glorious results — is for ever lost. That of the left, which was and is imperfect, is rendered null by continual weeping.

Galileo Galilei

A blade of grass is a commonplace on Earth; it would be a miracle on Mars. Our descendants on Mars will know the value of a patch of green. And if a blade of grass is priceless, what is the value of a human being?

Carl Sagan

As a consequence of the enormous social and technological changes of the last few centuries, the world is not working well. We do not live in traditional and static societies. But our government, in resisting change, act as if we did. Unless we destroy ourselves utterly, the future belongs to those societies that, while not ignoring the reptilian and mammalian parts of our being, enable the characteristically human components of our nature to flourish; to those societies that encourage diversity rather than conformity; to those societies willing to invest resources in a variety of social, political, economic and cultural experiments, and prepared to sacrifice short-term advantage for long-term benefit; to those societies that treat new ideas as delicate, fragile and immensely valuable pathways to the future.

Carl Sagan

Consider again that dot [Earth]. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there - on a mote of dust suspended in a sunbeam.

Carl Sagan

To know that we know what we know, and to know that we do not know what we do not know, that is true knowledge.

Nicolaus Copernicus

There is nothing particularly special about that location of the centre of mass. If you were to find yourself at the precise spot that is the centre of mass of the earth-moon system, the only thing unusual that you would notice is that there would be one thousand miles of rock on top of your head.Pluto is only about twice the size of Charon, so if you put Pluto and Charon on the cosmic seesaw you would find that the balance point is a little bit outside Pluto, rather than inside it. Again, there is nothing particularly special going on there. If you were to find yourself at that precise spot, you would only notice that you were very, very cold and could no longer breathe.

Mike Brown

We have held the peculiar notion that a person or society that is a little different from us, whoever we are, is somehow strange or bizarre, to be distrusted or loathed. Think of the negative connotations of words like alien or outlandish. And yet the monuments and cultures of each of our civilizations merely represent different ways of being human. An extraterrestrial visitor, looking at the differences among human beings and their societies, would find those differences trivial compared to the similarities.

Carl Sagan

Mortal as I am, I know that I am born for a day. But when I follow at my pleasure the serried multitude of the stars in their circular course, my feet no longer touch the earth.

Ptolemy

Advances in medicine and agriculture have saved vastly more lives than have been lost in all the wars in history.

Carl Sagan

What a wonderful and amazing Scheme have we here of the magnificent Vastness of the Universe! So many Suns, so many Earths, and every one of them stock’d with so many Herbs, Trees and Animals, and adorn’d with so many Seas and Mountains! And how must our wonder and admiration be encreased when we consider the prodigious distance and multitude of the Stars?

Christiaan Huygens

Tis of the tears which stars weep sweet with joy.

Francis Bailey

All this of Pot and Potter - Tell me then Who is the Potter pray and who the Pot?

Omar Khayyám

I’m tired of ignorance held up as inspiration, where vicious anti-intellectualism is considered a positive trait, and where uninformed opinion is displayed as fact.

Philip Plait

In the vastness of space and the immensity of time, it is my joy to share a planet and an epoch with Annie.[Dedication to Sagan's wife, Ann Druyan, in Cosmos]

Carl Sagan

The secrets of evolution, are time and death. There's an unbroken thread that stretches from those first cells to us.

Carl Sagan

Humans — who enslave, castrate, experiment on, and fillet other animals — have had an understandable penchant for pretending animals do not feel pain. A sharp distinction between humans and 'animals' is essential if we are to bend them to our will, make them work for us, wear them, eat them — without any disquieting tinges of guilt or regret. It is unseemly of us, who often behave so unfeelingly toward other animals, to contend that only humans can suffer. The behavior of other animals renders such pretensions specious. They are just too much like us.

Carl Sagan

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.

Carl Sagan

In that case, on behalf of Earthlife, I urge that, with full knowledge of our limitations, we vastly increase our knowledge of the Solar System and then begin to settle other worlds.

Carl Sagan

Perchance you who pronounce my sentence are in greater fear than I who receive it.

Giordano Bruno

All over the world there are enormous numbers of smart, even gifted, people who harbor a passion for science. But that passion is unrequited. Surveys suggest that some 95 percent of Americans are “scientifically illiterate.” That’s just the same fraction as those African Americans, almost all of them slaves, who were illiterate just before the Civil War—when severe penalties were in force for anyone who taught a slave to read. Of course there’s a degree of arbitrariness about any determination of illiteracy, whether it applies to language or to science. But anything like 95 percent illiteracy is extremely serious.

Carl Sagan

We are star stuff which has taken its destiny into its own hands.

Carl Sagan

Plato is my friend, Aristotle is my friend, but my greatest friend is truth.

Isaac Newton

Where the senses fail us, reason must step in.

Galileo Galilei

Your Excellency, I have no need of this hypothesis.

Pierre-Simon Laplace

There were many women in the Soviet scientific community, proportionately more so than in the United States. But they tended to occupy menial middle-level positions, and male Soviet scientists, like their American counterparts, were puzzled about a pretty woman with evident scientific competence who forcefully expressed her views.

Carl Sagan

Much more plausible is the computer-based explanation that dreams are a spillover from the unconscious processing of the day's experience, from the brain's decision on how much of the daily events temporarily stored in a kind of buffer to emplace in long-term memory... The American psychiatrist Ernest Hartmann of Tufts University has providedanecdotal but reasonably persuasive evidence that people who are engaged in intellectual activities during the day, especially unfamiliar intellectual activities, require more sleep at night, while, by and large, those engaged in mainly repetitive and intellectually unchallenging tasks are able to do with much less sleep.

Carl Sagan

The sun, with all the planets revolving around it, and depending on it, can still ripen a bunch of grapes as though it had nothing else in the universe to do.

Galileo Galilei

There is something stunningly narrow about how the Anthropic Principle is phrased. Yes, only certain laws and constants of nature are consistent with our kind of life. But essentially the same laws and constants are required to make a rock. So why not talk about a Universe designed so rocks could one day come to be, and strong and weak Lithic Principles? If stones could philosophize, I imagine Lithic Principles would be at the intellectual frontiers.

Carl Sagan

n every culture, the sky and the religious impulse are intertwined. I lie back in an open field and the sky surrounds me. I’m overpowered by its scale. It’s so vast and so far away that my own insignificance becomes palpable. But I don’t feel rejected by the sky. I’m a part of it - tiny, to be sure, but everything is tiny compared to that overwhelming immensity. And when I concentrate in the stars, the planets, and their motions, I have an irresistible sense of machinery, clockwork, elegant precision working on a scale that, however lofty out aspirations, dwarfs and humbles us.

Carl Sagan

It seems to me what is called for is an exquisite balance between two conflicting needs: the most skeptical scrutiny of all hypotheses that are served up to us and at the same time a great openness to new ideas. Obviously those two modes of thought are in some tension. But if you are able to exercise only one of these modes, whichever one it is, you’re in deep trouble.If you are only skeptical, then no new ideas make it through to you. You never learn anything new. You become a crotchety old person convinced that nonsense is ruling the world. (There is, of course, much data to support you.) But every now and then, maybe once in a hundred cases, a new idea turns out to be on the mark, valid and wonderful. If you are too much in the habit of being skeptical about everything, you are going to miss or resent it, and either way you will be standing in the way of understanding and progress.On the other hand, if you are open to the point of gullibility and have not an ounce of skeptical sense in you, then you cannot distinguish the useful as from the worthless ones.

Carl Sagan

I have looked further into space than ever human being did before me. I have observed stars of which the light, it can be proved, must take two million years to reach the

William Herschel

For me, it is far better to grasp the Universe as it really is than to persist in delusion, however satisfying and reassuring.

Carl Sagan

Liberation from superstition is a necessary but not a sufficient condition for science.

Carl Sagan

To get he had tried,yet his store was still meager.To a wise man he cried,in a voice keen and eager;Pray tell me how I may successfully live?And the wise man replied,"To get you must give."As to giving he said,"What have I to give?"I've scarce enough bread,and of course one must live;But I would partake of Life's bountifulstore. Came the wise man's response;"Then you must give more."The lesson he learned;to get was forgotten,Toward mankind he turnedwith a love new begotten.As he gave of himself in useful living,Then joy crowned his days,for he grew rich in giving.

Arthur William Beer

My tomb shall be in a spot where the north wind may scatter roses over it.

Omar Khayyám

It matters not how long we live but how.

Francis Bailey

Understanding is a kind of ecstasy

Carl Sagan

All that we have seen is something of a vast and intricate and lovely universe. There is no particular theological conclusion that comes out of an exercise such as the one we have just gone through. What is more, when we understand something of the astronomical dynamics, the evolution of worlds, we recognize that worlds are born and worlds die, they have lifetimes just as humans do, and therefore that there is a great deal of suffering and death in the cosmos if there is a great deal of life.

Carl Sagan

The same few dozen organic molecules are used over and over again in biology for the widest variety of functions.

Carl Sagan

If the butterfly wings its way to the sweet light that attracts it, it's only becasue it doesn't know that the fire can consume it.

Giordano Bruno

There is a coherent plan to the universe, though I don't know what it's a plan for.

Fred Hoyle

The total amount of energy from outside the solar system ever received by all the radio telescopes on the planet Earth is less than the energy of a single snowflake striking the ground.

Carl Sagan

If you wish to make an apple pie from scratch, you must first invent the universe.

Carl Sagan

Who is more humble? The scientist who looks at the universe with an open mind and accepts whatever the universe has to teach us, or somebody who says everything in this book must be considered the literal truth and never mind the fallibility of all the human beings involved?

Carl Sagan

The sleeping style of each organism is exquisitelyadapted to the ecology of the animal. It is conceivable that animals who are too stupid to be quiet on their own initiative are, during periods of high risk, immobilized by the implacable arm of sleep.
