More quotes by Carl Sagan
Any sufficiently crisp question can be answered by a single binary digit-0 or 1, yes or no.
Carl Sagan
The method of science is tried and true. It is not perfect, it's just the best we have. And to abandon it, with its skeptical protocols, is the pathway to a dark age.
Carl Sagan
Looking at fires when high, by the way, especially through one of those prism kaleidoscopes which image their surroundings, is an extraordinarily moving and beautiful experience.
Carl Sagan
An atheist has to know a lot more than I know. An atheist is someone who knows there is no god. By some definitions atheism is very stupid.
Carl Sagan
The Cosmos is all that is or was or ever will be. Our feeblest contemplations of the Cosmos stir us -- there is a tingling in the spine, a catch in the voice, a faint sensation, as if a distant memory, of falling from a height. We know we are approaching the greatest of mysteries.
Carl Sagan
In many cultures it is customary to answer that God created the universe out of nothing. But this is mere temporizing. If we wish courageously to pursue the question, we must, of course ask next where God comes from? And if we decide this to be unanswerable, why not save a step and conclude that the universe has always existed?
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
There are more potential combinations of DNA [physical forms] than there are atoms in the universe.
Carl Sagan
If we can't think for ourselves, if we're unwilling to question authority, then we're just putty in the hands of those in power.
Carl Sagan
The total number of stars in the Universe is larger than all the grains of sand on all the beaches of the planet Earth.
Carl Sagan
The Cosmos is all that is or ever was or ever will be.
Carl Sagan
The illegality of cannabis is outrageous.
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
Books are key to understanding the world and participating in a democratic society.
Carl Sagan
A tiny blue dot set in a sunbeam. Here it is. That's where we live. That's home. We humans are one species and this is our world. It is our responsibility to cherish it. Of all the worlds in our solar system, the only one so far as we know, graced by life.
Carl Sagan
It does no harm to the romance of the sunset to know a little bit about it.
Carl Sagan
We invest far off places with a certain romance... Long summers, mild winters, rich harvests, plentiful game none of them lasts for ever. Your own life, or your bands, or even your species - might be owed to a restless few, drawn by a craving they can hardly articulate or understand, to undiscovered lands, and new worlds.
Carl Sagan
There is never only ONE of anything in nature.
Carl Sagan
The simplest thought, like the concept of the number one, has an elaborate logical underpinning.
Carl Sagan
Many religions have attempted to make statues of their gods very large, and the idea, I suppose, is to make us feel small. But if that's their purpose, they can keep their paltry icons. We need only look up if we wish to feel small.
Carl Sagan
