More quotes by 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
We are made of starstuff.
Carl Sagan
If the press descended, the science would surely suffer.
Carl Sagan
If we continue to accumulate only power and not wisdom, we will surely destroy ourselves.
Carl Sagan
Even Johannes Kepler, Isaac Newton, Charles Darwin, Gregor Mendel, and Albert Einstein made serious mistakes. But the scientific enterprise arranges things so that teamwork prevails: What one of us, even the most brilliant among us, misses, another of us, even someone much less celebrated and capable, may detect and rectify.
Carl Sagan
When you make the finding yourself - even if you're the last person on Earth to see the light - you'll never forget it.
Carl Sagan
I would love to believe that when I die I will live again, that some thinking, feeling, remembering part of me will continue.
Carl Sagan
Sailors on a becalmed sea, we sense the stirring of a breeze.
Carl Sagan
If the greenhouse effect is a blanket in which we wrap ourselves to keep warm, nuclear winter kicks the blanket off.
Carl Sagan
Arguments from authority carry little weight – authorities have made mistakes in the past. They will do so again in the future. Perhaps a better way to say it is that in science there are no authorities at most, there are experts.
Carl Sagan
There are more potential combinations of DNA [physical forms] than there are atoms in the universe.
Carl Sagan
And after we returned to the savannahs and abandoned the trees, did we long for those great graceful leaps and ecstatic moments of weightlessness in the shafts of sunlight of the forest roof?
Carl Sagan
If you are only skeptical, then no new ideas make it through to you.
Carl Sagan
We can't help it. Life looks for life.
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
Our loyalties are to the species and the planet. We speak for Earth.
Carl Sagan
You can get into a habit of thought in which you enjoy making fun of all those other people who don't see things as clearly as you do. We have to guard carefully against it.
Carl Sagan
In many cultures it is customary to answer that God created the universe out of nothing. But this is mere temporizing. If we wish courageously to pursue the question, we must, of course ask next where God comes from? And if we decide this to be unanswerable, why not save a step and conclude that the universe has always existed?
Carl Sagan
The Hindu religion is the only of the World's great faiths dedicated to the idea that the Cosmos itself undergoes an immense, indeed an infinite, number of deaths and rebirths.
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
