Not all birds can fly. What separates the flyers from the walkers is the ability to take off.

More quotes by Carl Sagan
Every one of us is, in the cosmic perspective, precious. If a human disagrees with you, let him live. In a hundred billion galaxies, you will not find another.
Carl Sagan
Modern science has been a voyage into the unknown, with a lesson in humility waiting at every stop. Many passengers would rather have stayed home.
Carl Sagan
My deeply held belief is that if a god of anything like the traditional sort exists, our curiosity and intelligence is provided by such a God. We would be unappreciative of that gift if we suppressed our passion to explore the universe and ourselves.
Carl Sagan
And you are made of a hundred trillion cells. We are, each of us, a multitude.
Carl Sagan
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
The fact is that far more crime and child abuse has been committed by zealots in the name of God, Jesus and Mohammed than has ever been committed in the name of Satan. Many people don’t like that statement, but few can argue with it.
Carl Sagan
Except in pure mathematics, nothing is known for certain (although much is certainly false).
Carl Sagan
In the long run, the aggressive civilizations destroy themselves, almost always. It's their nature. They can't help it.
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
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
The universe is a pretty big place. If it's just us, seems like an awful waste of space.
Carl Sagan
Man is a transitional animal. He is not the climax of creation
Carl Sagan
Writing a novel is like trying to solve a very long mathematical equation. Changing anything can change everything else.
Carl Sagan
If you want to make a [rhubarb] pie from scratch, first you have to create the universe.
Carl Sagan
Who are we, if not measured by our impact on others? That’s who we are! We’re not who we say we are, we’re not who we want to be - we are the sum of the influence and impact that we have, in our lives, on others.
Carl Sagan
Human beings have a demonstrated talent for self-deception when their emotions are stirred.
Carl Sagan
The Cosmos is all that is or ever was or ever will be.
Carl Sagan
We are, each of us, a multitude. Within us is a little universe.
Carl Sagan
There is today-in a time when old beliefs are withering-a kind of philosophical hunger, a need to know who we are and how we got here. It is an on-going search, often unconscious, for a cosmic perspective for humanity
Carl Sagan
While our behavior is still significantly controlled by our genetic inheritance, we have, through our brains, a much richer opportunity to blaze new behavioral and cultural pathways on short timescales.
Carl Sagan
