More quotes by Carl Sagan
Across the sea of space, the stars are other suns.
Carl Sagan
Much of human history can, I think, be described as a gradual and sometimes painful liberation from provincialism, the emerging awareness that there is more to the world than was generally believed by our ancestors.
Carl Sagan
You're capable of such beautiful dreams and such horrible nightmares.
Carl Sagan
The Earth is a very small stage in a vast cosmic arena.
Carl Sagan
Science arouses a soaring sense of wonder. But so does pseudoscience. Sparse and poor popularizations of science abandon ecological niches that pseudoscience promptly fills. If it were widely understood that claims to knowledge require adequate evidence before they can be accepted, there would be no room for pseudoscience.
Carl Sagan
The universe is not required to be in perfect harmony with human ambition.
Carl Sagan
Any civilization that doesn't develop space travel dies.
Carl Sagan
A celibate clergy is an especially good idea, because it tends to suppress any hereditary propensity toward fanaticism.
Carl Sagan
We go about our daily lives understanding almost nothing of the world.
Carl Sagan
I find science so much more fascinating than science fiction. It also has the advantage of being true.
Carl Sagan
We are like butterflies who flutter for a day and think it is forever.
Carl Sagan
Books are like seeds. They can lie dormant for centuries and then flower in the most unpromising soil.
Carl Sagan
I set before you two ways: You can use your technology to destroy yourselves or to carry you to the planets and the stars. It's up to you.
Carl Sagan
But I could be wrong.
Carl Sagan
Books permit us to voyage through time, to tap the wisdom of our ancestors.
Carl Sagan
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
Recent research shows that many children without enough to eat wind up with diminished capacity to understand and learn (“cognitive impairment” ). Children don't have to be starving for this to happen. Even mild undernourishment — the kind most common among poor people in America — can do it.
Carl Sagan
There are as many atoms in one molecule of DNA as there are stars in a typical galaxy.
Carl Sagan
The gears of poverty, ignorance, hopelessness and low self-esteem interact to create a kind of perpetual failure machine that grinds down dreams from generation to generation. We all bear the cost of keeping it running. Illiteracy is its linchpin.
Carl Sagan
That kind of skeptical, questioning, don't accept what authority tells you attitude of science - is also nearly identical to the attitude of mind necessary for a functioning democracy. Science and democracy have very consonant values and approaches, and I don't think you can have one without the other.
Carl Sagan
