A single message from space will show that it is possible to live through technological adolescence. . . . It is possible that the future of human civilization depends on the receipt of interstellar messages.

More quotes by Carl Sagan
Thus the recent rapid evolution of human intelligence is not only the cause of but also the only conceivable solution to the many serious problems that beset us.
Carl Sagan
Across the sea of space, the stars are other suns.
Carl Sagan
The gears of poverty, ignorance, hopelessness and low self-esteem interact to create a kind of perpetual failure machine that grinds down dreams from generation to generation. We all bear the cost of keeping it running. Illiteracy is its linchpin.
Carl Sagan
Human beings have a demonstrated talent for self-deception when their emotions are stirred.
Carl Sagan
If chimpanzees have consciousness, if they are capable of abstractions, do they not have what until now has been described as 'human rights'? How smart does a chimp have to be before killing him constitutes murder?
Carl Sagan
It is said that men may not be the dreams of the god, but rather that the gods are the dreams of men.
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 history can be viewed as a slowly dawning awareness that we are members of a larger group.
Carl Sagan
Real patriots ask questions.
Carl Sagan
I think if we ever reach the point where we think we thoroughly understand who we are and where we came from, we will have failed.
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
The surface of the Earth is the shore of the cosmic ocean. From it we have learned most of what we know. Recently, we have waded a little out to sea, enough to dampen our toes or, at most, wet our ankles. The water seems inviting. The ocean calls.
Carl Sagan
We go about our daily lives understanding almost nothing of the world.
Carl Sagan
Human beings grew up in forests we have a natural affinity for them. How lovely a tree is, straining toward the sky.
Carl Sagan
Virtually every major technological advance in the history of the human species - back to the invention of stone tools and the domestication of fire - has been ethically ambiguous.
Carl Sagan
If we ruin the earth, there is no place else to go
Carl Sagan
Advances in medicine and agriculture have saved vastly more lives than have been lost in all the wars in history.
Carl Sagan
Our intelligence is imperfect, surely, and newly arisen the ease with which it can be sweet-talked, overwhelmed, or subverted by other hardwired propensities - sometimes themselves disguised as the cool light of reason - is worrisome.
Carl Sagan
The universe is a pretty big place. If it's just us, seems like an awful waste of space.
Carl Sagan
Skeptical scrutiny is the means, in both science and religion, by which deep thoughts can be winnowed from deep nonsense.
Carl Sagan
