More quotes by Carl Sagan
We wish to find the truth, no matter where it lies. But to find the truth we need imagination and skepticism both. We will not be afraid to speculate, but we will be careful to distinguish speculation from fact.
Carl Sagan
If I finish a book a week, I will read only a few thousand books in my lifetime, about a tenth of a percent of the contents of the greatest libraries of our time. The trick is to know which books to read.
Carl Sagan
In the long run, the aggressive civilizations destroy themselves, almost always. It's their nature. They can't help it.
Carl Sagan
Extraordinary observations require extraordinary evidence to make them believable.
Carl Sagan
If we continue to accumulate only power and not wisdom, we will surely destroy ourselves.
Carl Sagan
The prediction of nuclear winter is drawn not, of course, from any direct experience with the consequences of global nuclear war, but rather from an investigation of the governing physics.
Carl Sagan
He sought a way to preserve the past. John Hershel was one of the founders of a new form of time travel.... a means to capture light and memories. He actually coined a word for it... photography. When you think about it, photography is a form of time travel. This man is staring at us from across the centuries, a ghost preserved by light.
Carl Sagan
We are made of starstuff.
Carl Sagan
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
Because men, compared to male chimps, have such relatively small testicles (large testicles indicate a species where many males mate, one after the other, with the same female), we might guess that promiscuous societies were uncommon in the immediate human past.
Carl Sagan
The notion that science and spirituality are somehow mutually exclusive does a disservice to both.
Carl Sagan
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.
Carl Sagan
There is in this Universe much of what seems to be design.
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
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
Advances in medicine and agriculture have saved vastly more lives than have been lost in all the wars in history.
Carl Sagan
We live in a society exquisitely dependent on science and technology, in which hardly anyone knows anything about science and technology.
Carl Sagan
The cannabis experience has greatly improved my appreciation for art, a subject which I had never much appreciated before.
Carl Sagan
At the extremes it is difficult to distinguish pseudoscience from rigid, doctrinaire religion.
Carl Sagan
The universe is a pretty big place. If it's just us, seems like an awful waste of space.
Carl Sagan
