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
Except for children (who don't know enough not to ask the important questions), few of us spendtime wondering why nature is the way it is . . .
Carl Sagan
I also wish that the Pledge of Allegiance were directed at the Constitution and the Bill of Rights, as it is when the President takes his oath of office, rather than to the flag and the nation
Carl Sagan
The total number of stars in the Universe is larger than all the grains of sand on all the beaches of the planet Earth.
Carl Sagan
He sought a way to preserve the past. John Hershel was one of the founders of a new form of time travel.... a means to capture light and memories. He actually coined a word for it... photography. When you think about it, photography is a form of time travel. This man is staring at us from across the centuries, a ghost preserved by light.
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
Except for fools and madmen, everyone knows that nuclear war would he an unprecedented human catastrophe.
Carl Sagan
We are the universe experiencing itself.
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
The desire to be connected with the cosmos reflects a profound reality, but we are connected not in the trivial ways that astrology promises, but in the deepest ways.
Carl Sagan
Every star may be a sun to someone.
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
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
Absolute certainty will always elude us. We will always be mired in error. The most each generation can hope for is to reduce the error. . . .
Carl Sagan
Because men, compared to male chimps, have such relatively small testicles (large testicles indicate a species where many males mate, one after the other, with the same female), we might guess that promiscuous societies were uncommon in the immediate human past.
Carl Sagan
An atheist is someone who is certain that God does not exist, someone who has compelling evidence against the existence of God. I know of no such compelling evidence.
Carl Sagan
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
The very act of understanding is a celebration of joining, merging, even if on a very modest scale, with the magnificence of the Cosmos.
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
It will not be we who reach Alpha Centauri, and the other nearby stars. It will be a species very like us - but with more of our strengths and fewer of our weaknesses.
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
