You mustn't think of the Universe as a wilderness. It hasn't been that for billions of years, he said. Think of it more as... ..cultivated.

More quotes by Carl Sagan
Books are like seeds. They can lie dormant for centuries and then flower in the most unpromising soil.
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
In our time, we have sifted the sands of Mars, we have established a presence there, we have fulfilled a century of dreams!
Carl Sagan
We are made of stellar ash. Our origin and evolution have been tied to distant cosmic events. The exploration of the cosmos is a voyage of self-discovery.
Carl Sagan
The Bill of Rights decoupled religion from the state, in part because so many religions were steeped in an absolutist frame of mind - each convinced that it alone had a monopoly on the truth and therefore eager for the state to impose this truth on others.
Carl Sagan
War is murder writ large.
Carl Sagan
Any sufficiently crisp question can be answered by a single binary digit-0 or 1, yes or no.
Carl Sagan
The vast distances that separate the stars are providential. Beings and worlds are quarantined from one another. The quarantine is lifted only for those with sufficient self-knowledge and judgment to have safely traveled from star to star.
Carl Sagan
Thus the recent rapid evolution of human intelligence is not only the cause of but also the only conceivable solution to the many serious problems that beset us.
Carl Sagan
Cutting off fundamental, curiosity-driven science is like eating the seed corn. We may have a little more to eat next winter but what will we plant so we and our children will have enough to get through the winters to come?
Carl Sagan
With insufficient data it is easy to go wrong.
Carl Sagan
The old appeals to racial, sexual and religious chauvinism to rabid nationalist fervor, are beginning not to work.
Carl Sagan
The Earth is a very small stage in a vast cosmic arena.
Carl Sagan
A new consciousness is developing which sees the earth as a single organism and recognizes that an organism at war with itself is doomed. We are one planet.
Carl Sagan
If you wish to make an apple pie from scratch, you must first invent the universe.
Carl Sagan
Many religions have attempted to make statues of their gods very large, and the idea, I suppose, is to make us feel small. But if that's their purpose, they can keep their paltry icons. We need only look up if we wish to feel small.
Carl Sagan
If there is life, then I believe we should do nothing to disturb that life. Mars then, belongs to the Martians, even if they are microbes.
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
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
We are the custodians of life's meaning.
Carl Sagan
