More quotes by Carl Sagan
I set before you two ways: You can use your technology to destroy yourselves or to carry you to the planets and the stars. It's up to you.
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
When you look more generally at life on Earth, you find that it is all the same kind of life. There are not many different kinds there's only one kind. It uses about fifty fundamental biological building blocks, organic molecules.
Carl Sagan
If intelligence is our only edge, we must learn to use it better, to shape it, to understand its limitations and deficiencies -- to use it as cats use stealth, as katydids use camouflage -- to make it the tool of our survival.
Carl Sagan
We invest far off places with a certain romance... Long summers, mild winters, rich harvests, plentiful game none of them lasts for ever. Your own life, or your bands, or even your species - might be owed to a restless few, drawn by a craving they can hardly articulate or understand, to undiscovered lands, and new worlds.
Carl Sagan
Whatever the reason you're on Mars, I'm glad you're there, and I wish I was with you.
Carl Sagan
Man is a transitional animal. He is not the climax of creation
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 only a Latin word for knowledge
Carl Sagan
Preserve and cherish the pale blue dot, the only home we've ever known.
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
Extraordinary claims demand extraordinary evidence
Carl Sagan
Virtually every major technological advance in the history of the human species - back to the invention of stone tools and the domestication of fire - has been ethically ambiguous.
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
We go about our daily lives understanding almost nothing of the world.
Carl Sagan
Those who seek power at any price detect a societal weakness, a fear that they can ride into office.
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
The idea that God is an oversized white male with a flowing beard, who sits in the sky and tallies the fall of every sparrow is ludicrous. But if by 'God,' one means the set of physical laws that govern the universe, then clearly there is such a God. This God is emotionally unsatisfying... it does not make much sense to pray to the law of gravity.
Carl Sagan
Is mankind alone in the universe? Or are there somewhere other intelligent beings looking up into their night sky from very different worlds and asking the same kind of question?
Carl Sagan
Books are like seeds. They can lie dormant for centuries and then flower in the most unpromising soil.
Carl Sagan
