For a long time the human instinct to understand was thwarted by facile religious explanations.
Carl Sagan -
We could not guess how different from us they (extraterrestrials) might be. It was hard enough to guess the intentions of our elected representatives in Washington.

A central lesson of science is that to understand complex issues (or even simple ones), we must try to free our minds of dogma and to guarantee the freedom to publish, to contradict, and to experiment. Arguments from authority are unacceptable.
Carl Sagan -
Modern science has been a voyage into the unknown, with a lesson in humility waiting at every stop. Many passengers would rather have stayed home.
Carl Sagan -
In many myths, the one possibility the gods are most anxious about is that humans will discover some secret of immortality or even... attempt to stride the high heavens. ...It's a little bit like the rich imposing poverty on the poor and then asking to be loved because of it.
Carl Sagan -
Jingoistic rhetoric and puerile self-congratulatory nationalism.
Carl Sagan -
Many harebrained interpretations were also widely available, especially in weekly newspapers.
Carl Sagan -
That kind of skeptical, questioning, 'don't accept what authority tells you' attitude of science - is also nearly identical to the attitude of mind necessary for a functioning democracy. Science and democracy have very consonant values and approaches, and I don't think you can have one without the other.

Many religions have attempted to make statues of their gods very large, and the idea, I suppose, is to make us feel small. But if that's their purpose, they can keep their paltry icons. We need only look up if we wish to feel small.
Carl Sagan -
Nobody listens to mathematicians.
Carl Sagan -
Human beings have a demonstrated talent for self-deception when their emotions are stirred.
Carl Sagan -
If we like them, they’re freedom fighters, she thought. If we don’t like them, they’re terrorists. In the unlikely case we can’t make up our minds, they’re temporarily only guerrillas.
Carl Sagan -
Our loyalties are to the species and the planet. We speak for Earth. Our obligation to survive and flourish is owed not just to ourselves, but also to that Cosmos, ancient and vast, from which we spring.
Carl Sagan -
If a Creator God exists, would He or She or It... prefer a kind of sodden blockhead who worships while understanding nothing? Or would He prefer His votaries to admire the real universe in all its intracacy?
Carl Sagan
-
This vast number of worlds, the enormous scale of the universe... has not been taken into account, even superficially, in virtually no religion, and especially in no Western religions.
Carl Sagan -
Other things being equal, it is better to be smart than to be stupid.
Carl Sagan -
The Cosmos is all that is or ever was or ever will be. Our feeblest contemplations of the Cosmos stir us - there is a tingling in the spine, a catch in the voice, a faint sensation as if a distant memory, of falling from a height. We know we are approaching the greatest of mysteries.
Carl Sagan -
Science is, at least in part, informed worship.
Carl Sagan -
Every kid starts out as a natural-born scientist, and then we beat it out of them. A few trickle through the system with their wonder and enthusiasm for science intact.
Carl Sagan -
We have heard the rationales offered by the nuclear superpowers. We know who speaks for the nations. But who speaks for the human species? Who speaks for Earth?
