Carl Sagan
The wind whips through the canyons of the American Southwest, and there is no one to hear it but us - a reminder of the 40,000 generations of thinking men and women who preceded us, about whom we know almost nothing, upon whom our civilization is based.
Carl Sagan
In more than one respect, the exploring of the Solar System and homesteading other worlds constitutes the beginning, much more than the end, of history.
Carl Sagan
The universe seems neither benign nor hostile, merely indifferent.
Carl Sagan
The Cosmos is all that is or ever was or ever will be.
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

Carl Sagan
