Is mankind alone in the universe? Or are there somewhere other intelligent beings looking up into their night sky from very different worlds and asking the same kind of question?

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
What's the harm of a little mystification? It sure beats boring statistical analyses.
Carl Sagan
A stars rich in europium of distant galaxies analyzed through the collective light of a hundred billion constituent stars. Astronomical spectroscopy is an almost magical technique. It amazes me still. Auguste Comte picked a particularly unfortunate example.
Carl Sagan
My deeply held belief is that if a god of anything like the traditional sort exists, our curiosity and intelligence is provided by such a God. We would be unappreciative of that gift if we suppressed our passion to explore the universe and ourselves.
Carl Sagan
The idea that God is an oversized white male with a flowing beard, who sits in the sky and tallies the fall of every sparrow is ludicrous. But if by 'God,' one means the set of physical laws that govern the universe, then clearly there is such a God. This God is emotionally unsatisfying... it does not make much sense to pray to the law of gravity.
Carl Sagan
Science arouses a soaring sense of wonder. But so does pseudoscience. Sparse and poor popularizations of science abandon ecological niches that pseudoscience promptly fills. If it were widely understood that claims to knowledge require adequate evidence before they can be accepted, there would be no room for pseudoscience.
Carl Sagan
We are like butterflies who flutter for a day and think it is forever.
Carl Sagan
Extraordinary claim requires extraordinary proof.
Carl Sagan
I find science so much more fascinating than science fiction. It also has the advantage of being true.
Carl Sagan
Perhaps the depth of love can be calibrated by the number of different selves that are actively involved in a given relationship.
Carl Sagan
Which aspects of our nature will prevail is uncertain, particularly when our visions and prospects are bound to one small part of the small planet Earth. But up there in the Cosmos an inescapable perspective awaits.
Carl Sagan
Skeptical scrutiny is the means, in both science and religion, by which deep thoughts can be winnowed from deep nonsense.
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
You could just as well say that an agnostic is a deeply religious person with at least a rudimentary knowledge of human fallibility.
Carl Sagan
Chlorine is a deadly poison gas employed on European battlefields in World War I. Sodium is a corrosive metal which burns upon contact with water. Together they make a placid and unpoisonous material, table salt. Why each of these substances has the properties it does is a subject called chemistry.
Carl Sagan
The universe seems neither benign nor hostile, merely indifferent.
Carl Sagan
Any faith that admires truth, that strives to know God, must be brave enough to accommodate the universe.
Carl Sagan
When you make the finding yourself - even if you're the last person on Earth to see the light - you'll never forget it.
Carl Sagan
Every star may be a sun to someone.
Carl Sagan
These days there seems to be nowhere left to explore, at least on the land area of the Earth. Victims of their very success, the explorers now pretty much stay home.
Carl Sagan
