More quotes by Carl Sagan
The Platonists and their Christian successors held the peculiar notion that the Earth was tainted and somehow nasty, while the heavens were perfect and divine. The fundamental idea that the Earth is a planet, that we are citizens of the Universe, was rejected and forgotten.
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.
Carl Sagan
Man is the matter of the cosmos, contemplating itself.
Carl Sagan
Human history can be viewed as a slowly dawning awareness that we are members of a larger group.
Carl Sagan
The hole in the ozone layer is a kind of skywriting. At first it seemed to spell out our continuing complacency before a witch's brew of deadly perils. But perhaps it really tells of a newfound talent to work together to protect the global environment.
Carl Sagan
The very act of understanding is a celebration of joining, merging, even if on a very modest scale, with the magnificence of the Cosmos.
Carl Sagan
I find science so much more fascinating than science fiction. It also has the advantage of being true.
Carl Sagan
If we're capable of conjuring up terrifying monsters in childhood, why shouldn't some of us, at least on occasion, be able to fantasize something similar, something truly horrifying, a shared delusion, as adults?
Carl Sagan
Knowing a great deal is not the same as being smart intelligence is not information alone but also judgement, the manner in which information is coordinated and used.
Carl Sagan
We humans look rather different from a tree. Without a doubt we perceive the world differently than a tree does. But down deep, at the molecular heart of life, the trees and we are essentially identical.
Carl Sagan
There are as many atoms in one molecule of DNA as there are stars in a typical galaxy.
Carl Sagan
Extraordinary claims demand extraordinary evidence
Carl Sagan
Since, in the long run, every planetary society will be endangered by impacts from space, every surviving civilization is obliged to become spacefaring — not because of exploratory or romantic zeal, but for the most practical reason imaginable: staying alive.
Carl Sagan
UFOs: The reliable cases are uninteresting and in the interesting cases are unreliable.
Carl Sagan
Any sufficiently crisp question can be answered by a single binary digit-0 or 1, yes or no.
Carl Sagan
We are at a crossroads in human history. Never before has there been a moment so simultaneously perilous and promising. We are the first species to have taken evolution into our own hands.
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
Man is a transitional animal. He is not the climax of creation
Carl Sagan
Books are like seeds. They can lie dormant for centuries and then flower in the most unpromising soil.
Carl Sagan
Writing a novel is like trying to solve a very long mathematical equation. Changing anything can change everything else.
Carl Sagan
