More quotes by 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
The gears of poverty, ignorance, hopelessness and low self-esteem interact to create a kind of perpetual failure machine that grinds down dreams from generation to generation. We all bear the cost of keeping it running. Illiteracy is its linchpin.
Carl Sagan
It is the tension between creativity and skepticism that has produced the stunning and unexpected findings of science.
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
There are no forbidden questions in science, no matters too sensitive or delicate to be probed, no sacred truths.
Carl Sagan
The Platonists and their Christian successors held the peculiar notion that the Earth was tainted and somehow nasty, while the heavens were perfect and divine. The fundamental idea that the Earth is a planet, that we are citizens of the Universe, was rejected and forgotten.
Carl Sagan
In the vastness of the Cosmos there must be other civilizations far older and more advanced than ours.
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
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
Preserve and cherish the pale blue dot, the only home we've ever known.
Carl Sagan
Sailors on a becalmed sea, we sense the stirring of a breeze.
Carl Sagan
The notion that science and spirituality are somehow mutually exclusive does a disservice to both.
Carl Sagan
We have heard the rationales offered by the nuclear superpowers. We know who speaks for the nations. But who speaks for the human species? Who speaks for Earth?
Carl Sagan
The hole in the ozone layer is a kind of skywriting. At first it seemed to spell out our continuing complacency before a witch's brew of deadly perils. But perhaps it really tells of a newfound talent to work together to protect the global environment.
Carl Sagan
We are made of star-stuff. Our bodies are made of star-stuff. There are pieces of star within us all.
Carl Sagan
Understanding is a kind of ecstasy
Carl Sagan
We can't help it. Life looks for life.
Carl Sagan
Humans - who enslave, castrate, experiment on, and fillet other animals - have had an understandable penchant for pretending animals do not feel pain.
Carl Sagan
Knowing a great deal is not the same as being smart intelligence is not information alone but also judgement, the manner in which information is coordinated and used.
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
