Quote

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.

More quotes by Carl Sagan

Image
The Universe forces those who live in it to understand it. Those creatures who find everyday experience a muddled jumble of events with no predictability, no regularity, are in grave peril. The Universe belongs to those who, at least to some degree, have figured it out.
Carl Sagan
Image
What's the harm of a little mystification? It sure beats boring statistical analyses.
Carl Sagan
Image
Don't judge everyone else by your own limited experience.
Carl Sagan
Image
There is in this Universe much of what seems to be design.
Carl Sagan
Image
If the constellations had been named in the twentieth century, I suppose we would see bicycles and refrigerators in the sky.
Carl Sagan
Image
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
Image
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
Image
Scientists make mistakes. Accordingly, it is the job of the scientist to recognize our weakness, to examine the widest range of opinions, to be ruthlessly self-critical. Science is a collective enterprise with the error-correction machinery often running smoothly.
Carl Sagan
Image
Science is an attempt, largely successful, to understand the world, to get a grip on things, to get hold of ourselves, to steer a safe course. Microbiology and meteorology now explain what only a few centuries ago was considered sufficient cause to burn women to death.
Carl Sagan
Image
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
Image
If there is life, then I believe we should do nothing to disturb that life. Mars then, belongs to the Martians, even if they are microbes.
Carl Sagan
Image
Many religions have attempted to make statues of their gods very large, and the idea, I suppose, is to make us feel small. But if that's their purpose, they can keep their paltry icons. We need only look up if we wish to feel small.
Carl Sagan
Image
First rule in government spending: why build one when you can have two at twice the price?
Carl Sagan
Image
The universe is not required to be in perfect harmony with human ambition.
Carl Sagan
Image
Whatever the reason you're on Mars, I'm glad you're there, and I wish I was with you.
Carl Sagan
Image
The surface of the Earth is the shore of the cosmic ocean. From it we have learned most of what we know. Recently, we have waded a little out to sea, enough to dampen our toes or, at most, wet our ankles. The water seems inviting. The ocean calls.
Carl Sagan
Image
If we do not speak for Earth, who will? If we are not committed to our own survival, who will be?
Carl Sagan
Image
A multitude of aspects of the natural world that were considered miraculous only a few generations ago are now thoroughly understood in terms of physics and chemistry.
Carl Sagan
Image
The cure for a fallacious argument is a better argument, not the suppression of ideas.
Carl Sagan
Image
An atheist has to know a lot more than I know. An atheist is someone who knows there is no god. By some definitions atheism is very stupid.
