More quotes by 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.
Carl Sagan
In a complex universe, in a society undergoing unprecedented change, how can we find the truth if we are not willing to question everything and to give a fair hearing to everything?
Carl Sagan
Science is not only compatible with spirituality it is a profound source of spirituality.
Carl Sagan
Books permit us to voyage through time, to tap the wisdom of our ancestors.
Carl Sagan
I'd like the [Cosmos] series to be so visually stimulating that somebody who isn't even interested in the concepts will just watch for the effects. And I'd like people who are prepared to do some thinking to be really stimulated.
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
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
Our passion for learning ... is our tool for survival.
Carl Sagan
Some racists still reject the plain testimony written in the DNA that all the races are not only human but nearly indistinguishable. . . .
Carl Sagan
Extraordinary claims demand extraordinary evidence
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
Religions are often state-protected nurseries of pseudoscience, although there's no reason why religions have to play that role. In a way, it's an artefact from times long gone.
Carl Sagan
Real patriots ask questions.
Carl Sagan
Your religion assumes that people are children and need a boogeyman so they'll behave. You want people to believe in God so they'll obey the law. That's the only means that occurs to you: a strict secular police force, and the threat of punishment by an all-seeing God for whatever the police overlook. You sell human beings short.
Carl Sagan
There is a reward structure in science that is very interesting: Our highest honors go to those who disprove the findings of the most revered among us. So Einstein is revered not just because he made so many fundamental contributions to science, but because he found an imperfection in the fundamental contribution of Isaac Newton.
Carl Sagan
If we're capable of conjuring up terrifying monsters in childhood, why shouldn't some of us, at least on occasion, be able to fantasize something similar, something truly horrifying, a shared delusion, as adults?
Carl Sagan
There are lots of ways to communicate what we know, but few ways to communicate what we feel. Music is one way to communicate emotions.
Carl Sagan
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?
Carl Sagan
We can't help it. Life looks for life.
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
