Quote

Every one of us is, in the cosmic perspective, precious. If a human disagrees with you, let him live. In a hundred billion galaxies, you will not find another.

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 gears of poverty, ignorance, hopelessness and low self-esteem interact to create a kind of perpetual failure machine that grinds down dreams from generation to generation. We all bear the cost of keeping it running. Illiteracy is its linchpin.
Carl Sagan
Image
When you realize that no one really knows what they are doing and that everyone is doing the best they can according to their own level of consciousness, life gets a lot easier. Skeptical scrutiny is the means, in both science and religion, by which deep thoughts can be winnowed from deep nonsense.
Carl Sagan

Advances in medicine and agriculture have saved vastly more lives than have been lost in all the wars in history.
Carl Sagan

Science is not only compatible with spirituality it is a profound source of spirituality.

Whatever the reason you're on Mars, I'm glad you're there, and I wish I was with you.
Carl Sagan
Image
Human beings grew up in forests we have a natural affinity for them. How lovely a tree is, straining toward the sky.
Carl Sagan
Image
If intelligence is our only edge, we must learn to use it better, to shape it, to understand its limitations and deficiencies -- to use it as cats use stealth, as katydids use camouflage -- to make it the tool of our survival.
Carl Sagan
Image
Frederick Douglas taught that literacy is the path from slavery to freedom. There are many kinds of slavery and many kinds of freedom, but reading is still the path.
Carl Sagan
Image
Our ancestors worshipped the Sun, and they were not that foolish. It makes sense to revere the Sun and the stars, for we are their children.
Carl Sagan
Image
Except in pure mathematics, nothing is known for certain (although much is certainly false).
Carl Sagan
Image
Books are key to understanding the world and participating in a democratic society.
Carl Sagan
Image
Books are like seeds. They can lie dormant for centuries and then flower in the most unpromising soil.
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
Image
I set before you two ways: You can use your technology to destroy yourselves or to carry you to the planets and the stars. It's up to you.

Writing a novel is like trying to solve a very long mathematical equation. Changing anything can change everything else.
Carl Sagan
Image
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?

It is the tension between creativity and skepticism that has produced the stunning and unexpected findings of science.
Carl Sagan
Image
The surface of the Earth is the shore of the cosmic ocean. From it we have learned most of what we know. Recently, we have waded a little out to sea, enough to dampen our toes or, at most, wet our ankles. The water seems inviting. The ocean calls.
Carl Sagan

We are prodding, challenging, seeking contradictions or small, persistent residual errors, proposing alternative explanations, encouraging heresy. We give our highest rewards to those who convincingly disprove established beliefs.
