Quote

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.

In the fabric of space and in the nature of matter, as in a great work of art, there is, written small, the artist's signature.
Carl Sagan
Image
We are a way for the cosmos to know itself.
Carl Sagan
Image
Skeptical scrutiny is the means, in both science and religion, by which deep thoughts can be winnowed from deep nonsense.
Carl Sagan
Image
If we long to believe that the stars rise and set for us, that we are the reason there is a Universe, does science do us a disservice in deflating our conceits?
Carl Sagan
Image
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
Image
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.
Carl Sagan
Image
Any sufficiently crisp question can be answered by a single binary digit-0 or 1, yes or no.
Carl Sagan
Image
It's perilous and foolhardy for the average citizen to remain ignorant about global warming, say, or ozone depletion, air pollution, toxic and radioactive wastes, acid rain, topsoil erosion, tropical deforestation, exponential population growth. Jobs and wages depend on science and technology.
Carl Sagan
Image
Who are we, if not measured by our impact on others?
Carl Sagan
Image
Our ancestors lived out of doors. They were as familiar with the night sky as most of us are with our favorite television programs.
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
The dumbing down of American is most evident in the slow decay of substantive content in the enormously influential media, the 30 second sound bites (now down to 10 seconds or less), lowest common denominator programming, credulous presentations on pseudoscience and superstition, but especially a kind of celebration of ignorance.
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.
Carl Sagan
Image
There is a reward structure in science that is very interesting: Our highest honors go to those who disprove the findings of the most revered among us. So Einstein is revered not just because he made so many fundamental contributions to science, but because he found an imperfection in the fundamental contribution of Isaac Newton.
Carl Sagan
Image
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
Image
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
Image
Preserve and cherish the pale blue dot, the only home we've ever known.
Carl Sagan
Image
There is never only ONE of anything in nature.
Carl Sagan
Image
But I try not to think with my gut. If I'm serious about understanding the world, thinking with anything besides my brain, as tempting as that might be, is likely to get me into trouble.
Carl Sagan

We are, in the most profound sense, children of the Cosmos.
