Quote

An atheist is someone who is certain that God does not exist, someone who has compelling evidence against the existence of God. I know of no such compelling evidence.

If the press descended, the science would surely suffer.
Carl Sagan
Image
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
Image
If you wish to make an apple pie from scratch, you must first invent the universe.
Carl Sagan
Image
Some racists still reject the plain testimony written in the DNA that all the races are not only human but nearly indistinguishable. . . .
Carl Sagan
Image
The simplest thought, like the concept of the number one, has an elaborate logical underpinning.
Carl Sagan
Image
You mustn't think of the Universe as a wilderness. It hasn't been that for billions of years, he said. Think of it more as... ..cultivated.

In Mozambique, the story goes, monkeys do not talk, because they know if they utter even a single word some man will come and put them to work.
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
Image
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
Image
I believe that in every person is a kind of circuit which resonates to intellectual discovery-and the idea is to make that resonance work
Carl Sagan
Image
Man is a transitional animal. He is not the climax of creation
Carl Sagan
Image
The politicians and the religious leaders and the weapons scientists have been at it for a long time and they've made a thorough mess of it. I mean, we're in deep trouble.
Carl Sagan
Image
Scientists make mistakes. Accordingly, it is the job of the scientist to recognize our weakness, to examine the widest range of opinions, to be ruthlessly self-critical. Science is a collective enterprise with the error-correction machinery often running smoothly.
Carl Sagan
Image
We've arranged a civilization in which most crucial elements profoundly depend on science and technology.
Carl Sagan
Image
Otherwise we don't run the government the government runs us
Carl Sagan
Image
There is in this Universe much of what seems to be design.
Carl Sagan
Image
Books permit us to voyage through time, to tap the wisdom of our ancestors.
Carl Sagan
Image
For all I know we may be visited by a different extraterrestrial civilization every second Tuesday, but there's no support for this appealing idea. The extraordinary claims are not supported by extraordinary evidence.
Carl Sagan

The neurochemistry of the brain is astonishingly busy, the circuitry of a machine more wonderful than any devised by humans. But there is no evidence that its functioning is due to anything more than the 10(14) neural connections that build an elegant architecture of consciousness.
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.
