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.

More quotes by 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
The Universe forces those who live in it to understand it. Those creatures who find everyday experience a muddled jumble of events with no predictability, no regularity, are in grave peril. The Universe belongs to those who, at least to some degree, have figured it out.
Carl Sagan
All over the world there are enormous numbers of smart, even gifted, people who harbor a passion for science. But that passion is unrequited. Surveys suggest that some 95% of Americans are scientifically illiterate. That's...the same fraction...of slaves who were illiterate before the Civil War.
Carl Sagan
Even today the most jaded city dweller can be unexpectedly moved upon encountering a clear night sky studded with thousands of twinkling stars. When it happens to me after all these years it still takes my breath away.
Carl Sagan
We are star stuff which has taken its destiny into its own hands.
Carl Sagan
Arguments from authority carry little weight – authorities have made mistakes in the past. They will do so again in the future. Perhaps a better way to say it is that in science there are no authorities at most, there are experts.
Carl Sagan
If you are only skeptical, then no new ideas make it through to you.
Carl Sagan
We are...capable of using our compassion and our intelligence, our technology and our wealth, to make an abundant and meaningful life for every inhabitant of this planet. To enhance enormously our understanding of the Universe, and to carry us to the stars.
Carl Sagan
The difference between physics and metaphysics is not that the practitioners of one are smarter than the practitioners of the other. The difference is that the metaphysicist has no laboratory.
Carl Sagan
Across the sea of space, the stars are other suns.
Carl Sagan
There is in this Universe much of what seems to be design.
Carl Sagan
The simplest thought, like the concept of the number one, has an elaborate logical underpinning.
Carl Sagan
We are, in the most profound sense, children of the Cosmos.
Carl Sagan
There is much that science doesn't understand, many mysteries still to be resolved. In a Universe tens of billions of light-years across and some ten or fifteen billion years old, this may be the case forever. We are constantly stumbling on new surprises
Carl Sagan
The dumbing down of America is evident in the slow decay of substantive content, a kind of celebration of ignorance.
Carl Sagan
The well-meaning contention that all ideas have equal merit seems to me little different from the disastrous contention that no ideas have any merit.
Carl Sagan
We live in an in-between universe where things change all right...but according to patterns, rules, or as we call them, laws of nature.
Carl Sagan
It took the Church until 1832 to remove Galileo 's work from its list of books which Catholics were forbidden to read at the risk of dire punishment of their immortal souls.
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
Knowing a great deal is not the same as being smart intelligence is not information alone but also judgement, the manner in which information is coordinated and used.
Carl Sagan
