Carl Sagan Quotes

Science cuts two ways, of course; its products can be used for both good and evil. But there’s no turning back from science. The early warnings about technological dangers also come from science Picture Quote #1

I believe that the extraordinary should be pursued. But extraordinary claims require extraordinary evidence Picture Quote #1

Anything else you’re interested in is not going to happen if you can’t breathe the air and drink the water. Don’t sit this one out. Do something. You are by accident of fate alive at an absolutely critical moment in the history of our planet Picture Quote #1

The politicians and the religious leaders and the weapons scientists have been at it for a long time and they’ve made a thorough mess of it. I mean, we’re in deep trouble Picture Quote #1

At the extremes it is difficult to distinguish pseudoscience from rigid, doctrinaire religion Picture Quote #1

Our children long for realistic maps of the future that they can be proud of. Where are the cartographers of human purpose? Picture Quote #1

We are at a crossroads in human history. Never before has there been a moment so simultaneously perilous and promising. We are the first species to have taken evolution into our own hands Picture Quote #1

Science is far from a perfect instrument of knowledge. It’s just the best we have Picture Quote #1

I don’t know the answer. Maybe no one knows. Maybe when you grow up, you’ll be the first to find out Picture Quote #1

History is full of people who out of fear, or ignorance, or lust for power has destroyed knowledge of immeasurable value which truly belongs to us all. We must not let it happen again Picture Quote #1

Absolute certainty will always elude us. We will always be mired in error. The most each generation can hope for is to reduce the error Picture Quote #1

I believe our future depends powerfully on how well we understand this cosmos in which we float, like a mote of dust in the morning sky Picture Quote #1

Religions are tough. Either they make no contentions which are subject to disproof or they quickly redesign doctrine after disproof... near the core of the religious experience is something remarkably resistant to rational inquiry Picture Quote #1

There are in fact 100 billion galaxies, each of which contain something like a 100 billion stars. Think of how many stars, and planets, and kinds of life there may be in this vast and awesome universe Picture Quote #1

How smart does a chimp have to be before killing him constitutes murder? Picture Quote #1

If constellations had been named in the 20th century, I suppose we would see bicycles Picture Quote #1

The old appeals to racial, sexual and religious chauvinism to rabid nationalist fervor, are beginning not to work Picture Quote #1

The simplest thought, like the concept of the number one, has an elaborate logical underpinning Picture Quote #1

The open road still softly calls, like a nearly forgotten song of childhood Picture Quote #1

On the day that we do discover that we are not alone, our society may begin to evolve and transform in some incredible and wondrous new ways Picture Quote #1

In the deepest sense the search for extraterrestrial intelligence is a search for ourselves Picture Quote #1

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 Picture Quote #1

Widespread intellectual and moral docility may be convenient for leaders in the short term, but it is suicidal for nations in the long term. One of the criteria for national leadership should therefore be a talent for understanding, encouraging, and making constructive use of vigorous criticism Picture Quote #1

One of the saddest lessons of history is this: If we’ve been bamboozled long enough, we tend to reject any evidence of the bamboozle. We’re no longer interested in finding out the truth. The bamboozle has captured us. It’s simply too painful to acknowledge, even to ourselves, that we’ve been taken. Once you give a charlatan power over you, you almost never get it back Picture Quote #1

The truth may be puzzling. It may take some work to grapple with. It may be counterintuitive. It may contradict deeply held prejudices. It may not be consonant with what we desperately want to be true. But our preferences do not determine what’s true Picture Quote #1

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 Picture Quote #1

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 Picture Quote #1

For all our conceits about being the center of the universe, we live in a routine planet of a humdrum star stuck away in an obscure corner... on an unexceptional galaxy which is one of about 100 billion galaxies... That is the fundamental fact of the universe we inhabit, and it is very good for us to understand that Picture Quote #1

It is the responsibility of scientists never to suppress knowledge, no matter how awkward that knowledge is, no matter how it may bother those in power; we are not smart enough to decide which pieces of knowledge are permissible, and which are not Picture Quote #1

It’s perilous and foolhardy for the average citizen to remain ignorant about global warming, say, or ozone depletion, air pollution, toxic and radioactive wastes, acid rain, topsoil erosion, tropical deforestation, exponential population growth. Jobs and wages depend on science and technology Picture Quote #1
