For small creatures such as we the vastness is bearable only through love.


Every one of us is, in the cosmic perspective, precious. If a human disagrees with you, let him live. In a hundred billion galaxies, you will not find another.


All of us cherish our beliefs. They are, to a degree, self-defining. When someone comes along who challenges our belief system as insufficiently well-based – or who, like Socrates, merely asks embarrassing questions that we haven’t thought of, or demonstrates that we’ve swept key underlying assumptions under the rug – it becomes much more than a search for knowledge. It feels like a personal assault.

Carl Sagan Quotes about Humanity

We are, in a way, temporary ambulatory repositories for our nucleic acids. This does not deny our humanity; it does not prevent us from pursuing the good, the true and the beautiful. But it would be a great mistake to ignore where we have come from in our attempt to determine where we are going.


Every one of us is, in the cosmic perspective, precious. If a human disagrees with you, let him live. In a hundred billion galaxies, you will not find another.


There is today-in a time when old beliefs are withering-a kind of philosophical hunger, a need to know who we are and how we got here. It is an on-going search, often unconscious, for a cosmic perspective for humanity


We live in a vast and awesome universe in which, daily, suns are made and worlds destroyed, where humanity clings to an obscure clod of rock.

Carl Sagan Quotes about Earth

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.


A new consciousness is developing which sees the earth as a single organism and recognizes that an organism at war with itself is doomed. We are one planet. One of the great revelations of the age of space exploration is the image of the earth finite and lonely, somehow vulnerable, bearing the entire human species through the oceans of space and time.


If we are to survive, our loyalties must be broadened further, to include the whole human community, the entire planet Earth.


We have heard the rationales offered by the nuclear superpowers. We know who speaks for the nations. But who speaks for the human species? Who speaks for Earth?

Carl Sagan Quotes on Science

Science is a way of thinking much more than it is a body of knowledge.


Somewhere, something incredible is waiting to be known.


Think of how many religions attempt to validate themselves with prophecy. Think of how many people rely on these prophecies, however vague, however unfulfilled, to support or prop up their beliefs. Yet has there ever been a religion with the prophetic accuracy and reliability of science? … No other human institution comes close.


We live in a society exquisitely dependent on science and technology, in which hardly anyone knows anything about science and technology.

Carl Sagan Quotes about War

The prediction of nuclear winter is drawn not, of course, from any direct experience with the consequences of global nuclear war, but rather from an investigation of the governing physics.


A new consciousness is developing which sees the earth as a single organism and recognizes that an organism at war with itself is doomed. We are one planet. One of the great revelations of the age of space exploration is the image of the earth finite and lonely, somehow vulnerable, bearing the entire human species through the oceans of space and time.


Since World War II, Japan has spawned enormous numbers of new religions featuring the supernatural…. In Thailand, diseases are treated with pills manufactured from pulverized sacred Scripture. Witches are today being burned in South Africa…. The worldwide TM [Transcendental Meditation] organization has an estimated valuation of $3 billion. For a fee, they promise to make you invisible, to enable you to fly.


Centuries hence, when current social and political problems may seem as remote as the problems of the Thirty Years’ War are to us, our age may be remembered chiefly for one fact: It was the time when the inhabitants of the earth first made contact with the vast cosmos in which their small planet is embedded.

Carl Sagan Quotes on Writing

Writing a novel is like trying to solve a very long mathematical equation. Changing anything can change everything else.


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.

Writing is perhaps the greatest of human inventions.

Carl Sagan Quotes about Universe

Life is but a momentary glimpse of the wonder of this astonishing universe, and it is sad to see so many dreaming it away on spiritual fantasy.


Imagination will often carry us to worlds that never were. But without it we go nowhere.


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?


Somewhere, something incredible is waiting to be known.

Carl Sagan Quotes on Education

One of the greatest gifts adults can give – to their offspring and to their society – is to read to children.


We live in a society exquisitely dependent on science and technology, in which hardly anyone knows anything about science and technology.


The fact that someone says something doesn’t mean it’s true. Doesn’t mean they’re lying, but it doesn’t mean it’s true.


Our species needs, and deserves, a citizenry with minds wide awake and a basic understanding of how the world works.

Carl Sagan Quotes about Technology

We are…capable of using our compassion and our intelligence, our technology and our wealth, to make an abundant and meaningful life for every inhabitant of this planet. To enhance enormously our understanding of the Universe, and to carry us to the stars.


We live in a society exquisitely dependent on science and technology, in which hardly anyone knows anything about science and technology.


Societies will, of course, wish to exercise prudence in deciding which technologies that is, which applications of science are to be pursued and which not. But without funding basic research, without supporting the acquisition of knowledge for its own sake, our options become dangerously limited.


We have also arranged things so that almost no one understands science and technology. This is a prescription for disaster. We might get away with it for a while, but sooner or later this combustible mixture of ignorance and power is going to blow up in our faces.

Carl Sagan Quotes about Skepticism

I maintain there is much more wonder in science than in pseudoscience. And in addition, to whatever measure this term has any meaning, science has the additional virtue, and it is not an inconsiderable one, of being true.


It is far better to grasp the universe as it really is than to persist in delusion, however satisfying and reassuring.


In science it often happens that scientists say, ‘You know that’s a really good argument; my position is mistaken,’ and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn’t happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.


Skeptical scrutiny is the means, in both science and religion, by which deep thoughts can be winnowed from deep nonsense.

Carl Sagan Quotes on Ufos

We can make a similar examination, but with greater uncertainty, of the extraterrestrial hypothesis that holds that a wide range of UFOs viewed on the planet Earth are space vehicles from planets of other stars.


After I give lectures-on almost any subject-I am often asked, “Do you believe in UFOs?” I’m always struck by how the question is phrased, the suggestion that this is a matter of belief and not evidence. I’m almost never asked, “How good is the evidence that UFOs are alien spaceships?”


For years I’ve been stressing with regard to UFOs that extraordinary claims require extraordinary evidence.


UFOs: The reliable cases are uninteresting and in the interesting cases are unreliable.

Carl Sagan Quotes on space

We are star stuff which has taken its destiny into its own hands. The loom of time and space works the most astonishing transformations of matter.


A new consciousness is developing which sees the earth as a single organism and recognizes that an organism at war with itself is doomed. We are one planet. One of the great revelations of the age of space exploration is the image of the earth finite and lonely, somehow vulnerable, bearing the entire human species through the oceans of space and time.


We on Earth have just awakened to the great oceans of space and time from which we have emerged.


If our long-term survival is at stake, we have a basic responsibility to our species to venture to other worlds. Sailors on a becalmed sea, we sense the stirring of a breeze.

Carl Sagan Quotes about Aliens

After I give lectures-on almost any subject-I am often asked, “Do you believe in UFOs?” I’m always struck by how the question is phrased, the suggestion that this is a matter of belief and not evidence. I’m almost never asked, “How good is the evidence that UFOs are alien spaceships?”


If some good evidence for life after death were announced, I’d be eager to examine it; but it would have to be real scientific data, not mere anecdote. As with the face on Mars and alien abductions, better the hard truth, I say, than the comforting fantasy.


Is mankind alone in the universe? Or are there somewhere other intelligent beings looking up into their night sky from very different worlds and asking the same kind of question?

Carl Sagan Quotes about Nature

Except for children (who don’t know enough not to ask the important questions), few of us spendtime wondering why nature is the way it is


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


The passion to explore is at the heart of being human.


Extinction is the rule. Survival is the exception.

Carl Sagan Quotes on Time

In the vastness of space and the immensity of time, it is my joy to share a planet and an epoch with Annie.


We are like butterflies who flutter for a day and think it is forever.


For a long time the human instinct to understand was thwarted by facile religious explanations.


To read is to voyage through time.

Carl Sagan Quotes on Books

All of the books in the world contain no more information than is broadcast as video in a single large American city in a single year. Not all bits have equal value.


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.


It took the Church until 1832 to remove Galileo ‘s work from its list of books which Catholics were forbidden to read at the risk of dire punishment of their immortal souls.


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 Quotes Extraterrestrial Life

Discussing the possibilities of extraterrestrial life: I would love it even if they were short, sullen, grumpy and sexually obsessed. But there just isn’t any good evidence.


I’m frequently asked, “Do you believe there’s extraterrestrial intelligence?” I give the standard arguments- there are a lot of places out there, the molecules of life are everywhere, I use the word billions, and so on. Then I say it would be astonishing to me if there weren’t extraterrestrial intelligence, but of course there is as yet no compelling evidence for it. Often, I’m asked next, “What do you really think?” I say, “I just told you what I really think.” “Yes, but what’s your gut feeling?” But I try not to think with my gut. If I’m serious about understanding the world, thinking with anything besides my brain, as tempting as that might be, is likely to get me into trouble. Really, it’s okay to reserve judgment until the evidence is in.”

Carl Sagan Quotes about mathematics

I believe that even a smattering of such findings in modern science and mathematics is far more compelling and exciting than most of the doctrines of pseudoscience, whose practitioners were condemned as early as the fifth century B.C. by the Ionian philosopher Heraclitus as “nigh -walkers, magicians, priests of Bacchus, priestesses of the wine-vat, mystery-mongers.” But science is more intricate and subtle, reveals a much richer imiverse, and powerfully evokes our sense of wonder.


Except in pure mathematics, nothing is known for certain (although much is certainly false).


[Kepler] preferred the hard truth to his dearest illusions, and that is the heart of science.


In a lot of scientists, the ratio of wonder to skepticism declines in time. That may be connected with the fact that in some fields-mathematics, physics, some others-the great discoveries are almost entirely made by youngsters.

Carl Sagan Motivational Quotes

Who are we, if not measured by our impact on others? That’s who we are! We’re not who we say we are, we’re not who we want to be – we are the sum of the influence and impact that we have, in our lives, on others.


We live in a society exquisitely dependent on science and technology, in which hardly anyone knows anything about science and technology.


If we say that God has always been, why not save a step and conclude that the universe has always been?


We have also arranged things so that almost no one understands science and technology. This is a prescription for disaster. We might get away with it for a while, but sooner or later this combustible mixture of ignorance and power is going to blow up in our faces.

Carl Sagan Quotes on Astronomy

The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand. It has been said that astronomy is a humbling and character-building experience….. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we’ve ever known.


Somewhere, something incredible is waiting to be known.


There is perhaps no better a demonstration of the folly of human conceits than this distant image of our tiny world.


The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff.

Carl Sagan Quotes like a muscle

The brain is like a muscle. When it is in use we feel very good. Understanding is joyous.

Carl Sagan Quotes about Survival

Accommodation to change, the thoughtful pursuit of alternative futures are keys to the survival of civilization and perhaps of the human species.


Extinction is the rule. Survival is the exception.


Other Quotes You May Like:


Present global culture is a kind of arrogant newcomer. It arrives on the planetary stage following four and a half billion years of other acts, and after looking about for a few thousand years declares itself in possession of eternal truths. But in a world that is changing as fast as ours, this is a prescription for disaster. No nation, no religion, no economic system, no body of knowledge, is likely to have all the answers for our survival. There must be many social systems that would work far better than any now in existence. In the scientific tradition, our task is to find them.


If our long-term survival is at stake, we have a basic responsibility to our species to venture to other worlds. Sailors on a becalmed sea, we sense the stirring of a breeze.
