More quotes by Carl Sagan
Man is the matter of the cosmos, contemplating itself.
Carl Sagan
A single message from space will show that it is possible to live through technological adolescence. . . . It is possible that the future of human civilization depends on the receipt of interstellar messages.
Carl Sagan
Every time you look up at the sky, every one of those points of light is a reminder that fusion power is extractable from hydrogen and other light elements, and it is an everyday reality throughout the Milky Way Galaxy.
Carl Sagan
Every thinking person fears nuclear war, and every technological state plans for it. Everyone knows it is madness, and every nation has an excuse
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
It does no harm to the romance of the sunset to know a little bit about it.
Carl Sagan
There are no forbidden questions in science, no matters too sensitive or delicate to be probed, no sacred truths.
Carl Sagan
The beauty of a living thing is not the atoms that go into it, but the way those atoms are put together.
Carl Sagan
She had studied the universe all her life, but had overlooked its clearest message: For small creatures such as we the vastness is bearable only through love.
Carl Sagan
Imagination will often carry us to worlds that never were. But without it we go nowhere.
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
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
At the extremes it is difficult to distinguish pseudoscience from rigid, doctrinaire religion.
Carl Sagan
Our passion for learning ... is our tool for survival.
Carl Sagan
The prediction of nuclear winter is drawn not, of course, from any direct experience with the consequences of global nuclear war, but rather from an investigation of the governing physics.
Carl Sagan
Science is only a Latin word for knowledge
Carl Sagan
We are not smart enough to decide which pieces of knowledge are permissible and which are not.
Carl Sagan
We are the custodians of life's meaning.
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
Books are key to understanding the world and participating in a democratic society.
