It is clear that the nations of the world now can only rise and fall together. It is not a question of one nation winning at the expense of another. We must all help one another or all perish together.

More quotes by Carl Sagan
Books permit us to voyage through time, to tap the wisdom of our ancestors.
Carl Sagan
Every thinking person fears nuclear war, and every technological state plans for it. Everyone knows it is madness, and every nation has an excuse
Carl Sagan
If you are only skeptical, then no new ideas make it through to you.
Carl Sagan
Human beings grew up in forests we have a natural affinity for them. How lovely a tree is, straining toward the sky.
Carl Sagan
We've arranged a civilization in which most crucial elements profoundly depend on science and technology.
Carl Sagan
Writing a novel is like trying to solve a very long mathematical equation. Changing anything can change everything else.
Carl Sagan
We are prodding, challenging, seeking contradictions or small, persistent residual errors, proposing alternative explanations, encouraging heresy. We give our highest rewards to those who convincingly disprove established beliefs.
Carl Sagan
The Apollo pictures of the whole Earth conveyed to multitudes something well known to astronomers: On the scale of the worlds - to say nothing of stars or galaxies - humans are inconsequential, a thin film of life on an obscure and solitary lump of rock and metal
Carl Sagan
He didn't want to believe. He wanted to know.
Carl Sagan
Which aspects of our nature will prevail is uncertain, particularly when our visions and prospects are bound to one small part of the small planet Earth. But up there in the Cosmos an inescapable perspective awaits.
Carl Sagan
The very act of understanding is a celebration of joining, merging, even if on a very modest scale, with the magnificence of the Cosmos.
Carl Sagan
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.
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
And after we returned to the savannahs and abandoned the trees, did we long for those great graceful leaps and ecstatic moments of weightlessness in the shafts of sunlight of the forest roof?
Carl Sagan
We are made of starstuff.
Carl Sagan
Books break the shackles of time, proof that humans can work magic.
Carl Sagan
We are not smart enough to decide which pieces of knowledge are permissible and which are not.
Carl Sagan
Except in pure mathematics, nothing is known for certain (although much is certainly false).
Carl Sagan
Personally, I would be delighted if there were a life after death, especially if it permitted me to continue to learn about this world and others, if it gave me a chance to discover how history turns out.
Carl Sagan
You could just as well say that an agnostic is a deeply religious person with at least a rudimentary knowledge of human fallibility.
