More quotes by Carl Sagan
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
Books are key to understanding the world and participating in a democratic society.
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
I believe that in every person is a kind of circuit which resonates to intellectual discovery-and the idea is to make that resonance work
Carl Sagan
Every star may be a sun to someone.
Carl Sagan
The nuclear arms race is like two sworn enemies standing waist deep in gasoline, one with three matches, the other with five.
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
Writing is perhaps the greatest of human inventions, binding together people who never knew each other, citizens of distant epochs. Books break the shackles of time. A book is proof that humans are capable of magic.
Carl Sagan
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
Science is more than a body of knowledge. It's a way of thinking: a way of skeptically interrogating the universe.
Carl Sagan
It took the Church until 1832 to remove Galileo 's work from its list of books which Catholics were forbidden to read at the risk of dire punishment of their immortal souls.
Carl Sagan
I'd like the [Cosmos] series to be so visually stimulating that somebody who isn't even interested in the concepts will just watch for the effects. And I'd like people who are prepared to do some thinking to be really stimulated.
Carl Sagan
Accommodation to change, the thoughtful pursuit of alternative futures are keys to the survival of civilization and perhaps of the human species.
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
Religions are often state-protected nurseries of pseudoscience, although there's no reason why religions have to play that role. In a way, it's an artefact from times long gone.
Carl Sagan
I think the discomfort that some people feel in going to the monkey cages at the zoo is a warning sign.
Carl Sagan
We are the universe experiencing itself.
Carl Sagan
Imagination will often carry us to worlds that never were. But without it we go nowhere.
Carl Sagan
Discussing the possibilities of extraterrestrial life: I would love it even if they were short, sullen, grumpy and sexually obsessed. But there just isn't any good evidence.
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?
Carl Sagan
