More quotes by Carl Sagan
A tiny blue dot set in a sunbeam. Here it is. That's where we live. That's home. We humans are one species and this is our world. It is our responsibility to cherish it. Of all the worlds in our solar system, the only one so far as we know, graced by life.
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
Frederick Douglas taught that literacy is the path from slavery to freedom. There are many kinds of slavery and many kinds of freedom, but reading is still the path.
Carl Sagan
The understanding of the intent of the artist which I can achieve when high sometimes carries over to when I’m down. This is one of many human frontiers which cannabis has helped me traverse.
Carl Sagan
Even today the most jaded city dweller can be unexpectedly moved upon encountering a clear night sky studded with thousands of twinkling stars. When it happens to me after all these years it still takes my breath away.
Carl Sagan
It seems madness to say, 'We're worried that they're going to become addicted to marijuana' -- there's no evidence whatever that it's an addictive drug, but even if it were, these people are dying, what are we saving them from?
Carl Sagan
Except in pure mathematics, nothing is known for certain (although much is certainly false).
Carl Sagan
We are...capable of using our compassion and our intelligence, our technology and our wealth, to make an abundant and meaningful life for every inhabitant of this planet. To enhance enormously our understanding of the Universe, and to carry us to the stars.
Carl Sagan
One trend that bothers me is the glorification of stupidity, that the media is reassuring people it's alright not to know anything. That to me is far more dangerous than a little pornography on the Internet.
Carl Sagan
Science is not perfect. It's often misused it's only a tool, but it's the best tool we have. Self-correcting , ever changing, applicable to everything: with this tool, we vanquish the impossible.
Carl Sagan
The Earth is a very small stage in a vast cosmic arena.
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
Human beings grew up in forests we have a natural affinity for them. How lovely a tree is, straining toward the sky.
Carl Sagan
Observation: I can't see a thing. Conclusion: Dinosaurs.
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
Our passion for learning ... is our tool for survival.
Carl Sagan
We live in a society exquisitely dependent on science and technology and yet have cleverly arranged things so that almost no one understands science and technology.
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
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
I don't want to believe. I want to know.
Carl Sagan
