More quotes by Carl Sagan
Real patriots ask questions.
Carl Sagan
The method of science is tried and true. It is not perfect, it's just the best we have. And to abandon it, with its skeptical protocols, is the pathway to a dark age.
Carl Sagan
He didn't want to believe. He wanted to know.
Carl Sagan
We are, in the most profound sense, children of the Cosmos.
Carl Sagan
Every time you look up at the sky, every one of those points of light is a reminder that fusion power is extractable from hydrogen and other light elements, and it is an everyday reality throughout the Milky Way Galaxy.
Carl Sagan
It seems madness to say, 'We're worried that they're going to become addicted to marijuana' -- there's no evidence whatever that it's an addictive drug, but even if it were, these people are dying, what are we saving them from?
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
Even today the most jaded city dweller can be unexpectedly moved upon encountering a clear night sky studded with thousands of twinkling stars. When it happens to me after all these years it still takes my breath away.
Carl Sagan
Science is a way to call the bluff of those who only pretend to knowledge. It is a bulwark against mysticism, against superstition, against religion misapplied to where it has no business being.
Carl Sagan
Advances in medicine and agriculture have saved vastly more lives than have been lost in all the wars in history.
Carl Sagan
Books are key to understanding the world and participating in a democratic society.
Carl Sagan
There are more potential combinations of DNA [physical forms] than there are atoms in the universe.
Carl Sagan
The visions we offer our children shape the future. It _matters_ what those visions are. Often they become self-fulfilling prophecies. Dreams are maps.
Carl Sagan
The neurochemistry of the brain is astonishingly busy, the circuitry of a machine more wonderful than any devised by humans. But there is no evidence that its functioning is due to anything more than the 10(14) neural connections that build an elegant architecture of consciousness.
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
The uniqueness of humans has been claimed on many grounds, but most often because of our tool-making, culture, language, reason and morality. We have them, the other animals don't, and -- so the argument goes -- that's that.
Carl Sagan
Preserve and cherish the pale blue dot, the only home we've ever known.
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
If I finish a book a week, I will read only a few thousand books in my lifetime, about a tenth of a percent of the contents of the greatest libraries of our time. The trick is to know which books to read.
Carl Sagan
The Big Bang is our modern scientific creation myth. It comes from the same human need to solve the cosmological riddle [Where did the universe come from?]
Carl Sagan
