There are no forbidden questions in science, no matters too sensitive or delicate to be probed, no sacred truths.
Carl Sagan
Image
Discussing the possibilities of extraterrestrial life: I would love it even if they were short, sullen, grumpy and sexually obsessed. But there just isn't any good evidence.
Carl Sagan
Image
In the fabric of space and in the nature of matter, as in a great work of art, there is, written small, the artist's signature.
Carl Sagan
Image
If we ruin the earth, there is no place else to go
Carl Sagan
Image
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
Image
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
Image
In the vastness of the Cosmos there must be other civilizations far older and more advanced than ours.
Carl Sagan
Image
It's perilous and foolhardy for the average citizen to remain ignorant about global warming, say, or ozone depletion, air pollution, toxic and radioactive wastes, acid rain, topsoil erosion, tropical deforestation, exponential population growth. Jobs and wages depend on science and technology.
Carl Sagan
Image
If the greenhouse effect is a blanket in which we wrap ourselves to keep warm, nuclear winter kicks the blanket off.
Carl Sagan
Image
The fact that some geniuses were laughed at does not imply that all who are laughed at are geniuses.
Carl Sagan
Image
The visions we offer our children shape the future. It _matters_ what those visions are. Often they become self-fulfilling prophecies. Dreams are maps.
Carl Sagan
Image
The open road still softly calls, like a nearly forgotten song of childhood
Carl Sagan
Image
One of the great commandments of science is: 'Mistrust arguments from authority.'
Carl Sagan
Image
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
Image
The dumbing down of America is evident in the slow decay of substantive content, a kind of celebration of ignorance.
Carl Sagan
Image
we make our world significant by the courage of our questions and the depth of our answers
Carl Sagan
Image
We are star stuff which has taken its destiny into its own hands.
Carl Sagan
Image
It is clear that the nations of the world now can only rise and fall together. It is not a question of one nation winning at the expense of another. We must all help one another or all perish together.
Carl Sagan
Image
Religions are often state-protected nurseries of pseudoscience, although there's no reason why religions have to play that role. In a way, it's an artefact from times long gone.
Carl Sagan
Image
Science arouses a soaring sense of wonder. But so does pseudoscience. Sparse and poor popularizations of science abandon ecological niches that pseudoscience promptly fills. If it were widely understood that claims to knowledge require adequate evidence before they can be accepted, there would be no room for pseudoscience.
