More quotes by Carl Sagan
Man is a transitional animal. He is not the climax of creation
Carl Sagan
If we are not able to ask skeptical questions, to interrogate those who tell us that something is true, to be skeptical of those in authority, then, we are up for grabs for the next charlatan (political or religious) who comes rambling along.
Carl Sagan
If we ruin the earth, there is no place else to go
Carl Sagan
Modern Darwinism makes it abundantly clear that many less ruthless traits, some not always admired by robber barons and Fuhrers - altruism, general intelligence, compassion - may be the key to survival.
Carl Sagan
After the earth dies, some 5 billion years from now, after it's burned to a crisp, or even swallowed by the Sun, there will be other worlds and stars and galaxies coming into being - and they will know nothing of a place once called Earth.
Carl Sagan
Indeed the reasoned criticism of a prevailing belief is a service to the proponents of that belief if they are incapable of defending it, they are well advised to abandon it. This self-questioning and error-correcting aspect of the scientific method is its most striking property.
Carl Sagan
I would love to believe that when I die I will live again, that some thinking, feeling, remembering part of me will continue.
Carl Sagan
We live in a society exquisitely dependent on science and technology and yet have cleverly arranged things so that almost no one understands science and technology.
Carl Sagan
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.
Carl Sagan
The method of science, as stodgy and grumpy as it may seem, is far more important than the findings of science.
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
A new consciousness is developing which sees the earth as a single organism and recognizes that an organism at war with itself is doomed. We are one planet.
Carl Sagan
Real patriots ask questions.
Carl Sagan
We have heard the rationales offered by the nuclear superpowers. We know who speaks for the nations. But who speaks for the human species? Who speaks for Earth?
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
Books are like seeds. They can lie dormant for centuries and then flower in the most unpromising soil.
Carl Sagan
We are made of starstuff.
Carl Sagan
Sailors on a becalmed sea, we sense the stirring of a breeze.
Carl Sagan
Who are we, if not measured by our impact on others?
Carl Sagan
Any sufficiently crisp question can be answered by a single binary digit-0 or 1, yes or no.
Carl Sagan
