If we can't think for ourselves, if we're unwilling to question authority, then we're just putty in the hands of those in power.

More quotes by 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
Thus the recent rapid evolution of human intelligence is not only the cause of but also the only conceivable solution to the many serious problems that beset us.
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
I would love to believe that when I die I will live again, that some thinking, feeling, remembering part of me will continue.
Carl Sagan
Whatever the reason you're on Mars, I'm glad you're there, and I wish I was with you.
Carl Sagan
Except for fools and madmen, everyone knows that nuclear war would he an unprecedented human catastrophe.
Carl Sagan
The fact that some geniuses were laughed at does not imply that all who are laughed at are geniuses.
Carl Sagan
Science is merely an extremely powerful method of winnowing what's true from what feels good.
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
If we ruin the earth, there is no place else to go
Carl Sagan
Humans - who enslave, castrate, experiment on, and fillet other animals - have had an understandable penchant for pretending animals do not feel pain.
Carl Sagan
Cutting off fundamental, curiosity-driven science is like eating the seed corn. We may have a little more to eat next winter but what will we plant so we and our children will have enough to get through the winters to come?
Carl Sagan
In many cultures it is customary to answer that God created the universe out of nothing. But this is mere temporizing. If we wish courageously to pursue the question, we must, of course ask next where God comes from? And if we decide this to be unanswerable, why not save a step and conclude that the universe has always existed?
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
The Cosmos is all that is or was or ever will be. Our feeblest contemplations of the Cosmos stir us -- there is a tingling in the spine, a catch in the voice, a faint sensation, as if a distant memory, of falling from a height. We know we are approaching the greatest of mysteries.
Carl Sagan
The old appeals to racial, sexual and religious chauvinism to rabid nationalist fervor, are beginning not to work.
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
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
I don't want to believe. I want to know.
Carl Sagan
You can get into a habit of thought in which you enjoy making fun of all those other people who don't see things as clearly as you do. We have to guard carefully against it.
Carl Sagan
