More quotes by Carl Sagan
My view is that if there is no evidence for it, then forget about it. An agnostic is somebody who doesn’t believe in something until there is evidence for it, so I’m agnostic.
Carl Sagan
Indeed the reasoned criticism of a prevailing belief is a service to the proponents of that belief if they are incapable of defending it, they are well advised to abandon it. This self-questioning and error-correcting aspect of the scientific method is its most striking property.
Carl Sagan
A tiny blue dot set in a sunbeam. Here it is. That's where we live. That's home. We humans are one species and this is our world. It is our responsibility to cherish it. Of all the worlds in our solar system, the only one so far as we know, graced by life.
Carl Sagan
The cannabis experience has greatly improved my appreciation for art, a subject which I had never much appreciated before.
Carl Sagan
In our time, we have sifted the sands of Mars, we have established a presence there, we have fulfilled a century of dreams!
Carl Sagan
Books are key to understanding the world and participating in a democratic society.
Carl Sagan
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. . . .
Carl Sagan
You're capable of such beautiful dreams and such horrible nightmares.
Carl Sagan
We are made of starstuff.
Carl Sagan
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.
Carl Sagan
She had studied the universe all her life, but had overlooked its clearest message: For small creatures such as we the vastness is bearable only through love.
Carl Sagan
We live in an in-between universe where things change all right...but according to patterns, rules, or as we call them, laws of nature.
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
Knowing a great deal is not the same as being smart intelligence is not information alone but also judgement, the manner in which information is coordinated and used.
Carl Sagan
If we do not speak for Earth, who will? If we are not committed to our own survival, who will be?
Carl Sagan
I think if we ever reach the point where we think we thoroughly understand who we are and where we came from, we will have failed.
Carl Sagan
If we are merely matter intricately assembled, is this really demeaning? If there's nothing here but atoms, does that make us less or does that make matter more?
Carl Sagan
Any civilization that doesn't develop space travel dies.
Carl Sagan
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.
Carl Sagan
The open road still softly calls, like a nearly forgotten song of childhood
Carl Sagan
