If we can't think for ourselves, if we're unwilling to question authority, then we're just putty in the hands of those in power.

More quotes by Carl Sagan
We are made of stellar ash. Our origin and evolution have been tied to distant cosmic events. The exploration of the cosmos is a voyage of self-discovery.
Carl Sagan
Not all birds can fly. What separates the flyers from the walkers is the ability to take off.
Carl Sagan
Science is merely an extremely powerful method of winnowing what's true from what feels good.
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
The suppression of uncomfortable ideas may be common in religion or in politics, but it is not the path to knowledge it has no in the endeavor of science. We do not know in advance who will discover fundamental insights.
Carl Sagan
Skeptical scrutiny is the means, in both science and religion, by which deep thoughts can be winnowed from deep nonsense.
Carl Sagan
The Big Bang is our modern scientific creation myth. It comes from the same human need to solve the cosmological riddle [Where did the universe come from?]
Carl Sagan
The way to find out about our place in the universe is by examining the universe and by examining ourselves - without preconceptions, with as unbiased a mind as we can muster.
Carl Sagan
Human beings have a demonstrated talent for self-deception when their emotions are stirred.
Carl Sagan
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
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
If our long-term survival is at stake, we have a basic responsibility to our species to venture to other worlds. Sailors on a becalmed sea, we sense the stirring of a breeze.
Carl Sagan
In the long run, the aggressive civilizations destroy themselves, almost always. It's their nature. They can't help it.
Carl Sagan
UFOs: The reliable cases are uninteresting and in the interesting cases are unreliable.
Carl Sagan
we make our world significant by the courage of our questions and the depth of our answers
Carl Sagan
Any faith that admires truth, that strives to know God, must be brave enough to accommodate the universe.
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
If you are only skeptical, then no new ideas make it through to you.
Carl Sagan
The method of science, as stodgy and grumpy as it may seem, is far more important than the findings of science.
Carl Sagan
Extraordinary claims demand extraordinary evidence
