More quotes by 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
If we teach only the findings and products of science - no matter how useful and even inspiring they may be - without communicating its critical method, how can the average person possibly distinguish science from pseudoscience?
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
The Hindu religion is the only of the World's great faiths dedicated to the idea that the Cosmos itself undergoes an immense, indeed an infinite, number of deaths and rebirths.
Carl Sagan
The old appeals to racial, sexual and religious chauvinism to rabid nationalist fervor, are beginning not to work.
Carl Sagan
The well-meaning contention that all ideas have equal merit seems to me little different from the disastrous contention that no ideas have any merit.
Carl Sagan
Our ancestors worshipped the Sun, and they were not that foolish. It makes sense to revere the Sun and the stars, for we are their children.
Carl Sagan
First rule in government spending: why build one when you can have two at twice the price?
Carl Sagan
If the constellations had been named in the twentieth century, I suppose we would see bicycles and refrigerators in the sky.
Carl Sagan
We are star stuff which has taken its destiny into its own hands.
Carl Sagan
We live at a moment when our relationships to each other, and to all other beings with whom we share this planet, are up for grabs.
Carl Sagan
If we ruin the earth, there is no place else to go
Carl Sagan
I don't want to believe. I want to know.
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
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.
Carl Sagan
The politicians and the religious leaders and the weapons scientists have been at it for a long time and they've made a thorough mess of it. I mean, we're in deep trouble.
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
A book is proof that humans are capable of working magic.
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
Real patriots ask questions.
Carl Sagan
