If the greenhouse effect is a blanket in which we wrap ourselves to keep warm, nuclear winter kicks the blanket off.
Carl Sagan
Image
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
Image
It is the responsibility of scientists never to suppress knowledge, no matter how awkward that knowledge is, no matter how it may bother those in power we are not smart enough to decide which pieces of knowledge are permissible, and which are not.
Carl Sagan
Image
Which aspects of our nature will prevail is uncertain, particularly when our visions and prospects are bound to one small part of the small planet Earth. But up there in the Cosmos an inescapable perspective awaits.
Carl Sagan
Image
If some good evidence for life after death were announced, I'd be eager to examine it but it would have to be real scientific data, not mere anecdote. As with the face on Mars and alien abductions, better the hard truth, I say, than the comforting fantasy.

If the press descended, the science would surely suffer.

We are like butterflies who flutter for a day and think it is forever.

First rule in government spending: why build one when you can have two at twice the price?

Across the sea of space, the stars are other suns.

Who are we, if not measured by our impact on others? That’s who we are! We’re not who we say we are, we’re not who we want to be - we are the sum of the influence and impact that we have, in our lives, on others.
Carl Sagan

We are the universe experiencing itself.
Carl Sagan
Image
A single message from space will show that it is possible to live through technological adolescence. . . . It is possible that the future of human civilization depends on the receipt of interstellar messages.
Carl Sagan
Image
I set before you two ways: You can use your technology to destroy yourselves or to carry you to the planets and the stars. It's up to you.

A stars rich in europium of distant galaxies analyzed through the collective light of a hundred billion constituent stars. Astronomical spectroscopy is an almost magical technique. It amazes me still. Auguste Comte picked a particularly unfortunate example.
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?

Life is but a momentary glimpse of the wonder of this astonishing universe, and it is sad to see so many dreaming it away on spiritual fantasy.
Carl Sagan

All over the world there are enormous numbers of smart, even gifted, people who harbor a passion for science. But that passion is unrequited. Surveys suggest that some 95% of Americans are scientifically illiterate. That's...the same fraction...of slaves who were illiterate before the Civil War.

Science is not perfect. It's often misused it's only a tool, but it's the best tool we have. Self-correcting , ever changing, applicable to everything: with this tool, we vanquish the impossible.

The old appeals to racial, sexual and religious chauvinism to rabid nationalist fervor, are beginning not to work.

The idea that God is an oversized white male with a flowing beard, who sits in the sky and tallies the fall of every sparrow is ludicrous. But if by 'God,' one means the set of physical laws that govern the universe, then clearly there is such a God. This God is emotionally unsatisfying... it does not make much sense to pray to the law of gravity.
