More quotes by Carl Sagan
Every star may be a sun to someone.
Carl Sagan
What began in deadly competition has helped us to see that global cooperation is the essential precondition for our survival. Travel is broadening. It's time to hit the road again.
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
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
A book is proof that humans are capable of working magic.
Carl Sagan
After the earth dies, some 5 billion years from now, after it's burned to a crisp, or even swallowed by the Sun, there will be other worlds and stars and galaxies coming into being - and they will know nothing of a place once called Earth.
Carl Sagan
If you want to save your child from polio, you can pray or you can inoculate....Try science.
Carl Sagan
Exploration is in our nature. We began as wanderers, and we are wanderers still. We have lingered long enough on the shores of the cosmic ocean. We are ready at last to set sail for the stars.
Carl Sagan
Those with the courage to explore the weave and structure of the Cosmos, even where it differs profoundly from their wishes and prejudices, will penetrate its deepest mysteries.
Carl Sagan
I am often amazed at how much more capability and enthusiasm for science there is among elementary school youngsters than among college students.
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
Books tap the wisdom of our species -- the greatest minds, the best teachers -- from all over the world and from all our history. And they're patient.
Carl Sagan
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
Science is not only compatible with spirituality it is a profound source of spirituality.
Carl Sagan
Our ancestors worshipped the Sun, and they were not that foolish. It makes sense to revere the Sun and the stars, for we are their children.
Carl Sagan
There are as many atoms in one molecule of DNA as there are stars in a typical galaxy.
Carl Sagan
Which aspects of our nature will prevail is uncertain, particularly when our visions and prospects are bound to one small part of the small planet Earth. But up there in the Cosmos an inescapable perspective awaits.
Carl Sagan
The neurochemistry of the brain is astonishingly busy, the circuitry of a machine more wonderful than any devised by humans. But there is no evidence that its functioning is due to anything more than the 10(14) neural connections that build an elegant architecture of consciousness.
Carl Sagan
Preserve and cherish the pale blue dot, the only home we've ever known.
Carl Sagan
The Universe forces those who live in it to understand it. Those creatures who find everyday experience a muddled jumble of events with no predictability, no regularity, are in grave peril. The Universe belongs to those who, at least to some degree, have figured it out.
Carl Sagan
