More quotes by Carl Sagan
With insufficient data it is easy to go wrong.
Carl Sagan
In the long run, the aggressive civilizations destroy themselves, almost always. It's their nature. They can't help it.
Carl Sagan
I am not an atheist. An atheist is someone who has compelling evidence that there is no Judeo-Christian-Islamic God. I am not that wise, but neither do I consider there to be anything approaching adequate evidence for such a god. Why are you in such a hurry to make up your mind? Why not simply wait until there is compelling evidence?
Carl Sagan
And you are made of a hundred trillion cells. We are, each of us, a multitude.
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
Those who seek power at any price detect a societal weakness, a fear that they can ride into office.
Carl Sagan
Virtually every major technological advance in the history of the human species - back to the invention of stone tools and the domestication of fire - has been ethically ambiguous.
Carl Sagan
Skeptical scrutiny is the means, in both science and religion, by which deep thoughts can be winnowed from deep nonsense.
Carl Sagan
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.
Carl Sagan
It is far better to grasp the universe as it really is than to persist in delusion, however satisfying and reassuring.
Carl Sagan
In the fabric of space and in the nature of matter, as in a great work of art, there is, written small, the artist's signature.
Carl Sagan
They (i. e., the Pythagoreans) did not advocate the free confrontation of conflicting points of view. Instead, like all orthodox religions, they practised a rigidity that prevented them from correcting their errors.
Carl Sagan
Accommodation to change, the thoughtful pursuit of alternative futures are keys to the survival of civilization and perhaps of the human species.
Carl Sagan
We are, in the most profound sense, children of the Cosmos.
Carl Sagan
Human beings have a demonstrated talent for self-deception when their emotions are stirred.
Carl Sagan
We are star stuff which has taken its destiny into its own hands.
Carl Sagan
But I could be wrong.
Carl Sagan
Books tap the wisdom of our species -- the greatest minds, the best teachers -- from all over the world and from all our history. And they're patient.
Carl Sagan
We are the universe experiencing itself.
Carl Sagan
What an astonishing thing a book is.
Carl Sagan
