Quote

We humans look rather different from a tree. Without a doubt we perceive the world differently than a tree does. But down deep, at the molecular heart of life, the trees and we are essentially identical.

I don?t feel rejected by the sky. I?m a part of it- tiny, to be sure, but everything is tiny compared to that overwhelming immensity.
Carl Sagan
Image
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
Image
The evidence, so far at least and laws of Nature aside, does not require a Designer. Maybe there is one hiding, maddeningly unwilling to be revealed.
Carl Sagan

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

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.

If some good evidence for life after death were announced, I'd be eager to examine it but it would have to be real scientific data, not mere anecdote. As with the face on Mars and alien abductions, better the hard truth, I say, than the comforting fantasy.
Carl Sagan

A single message from space will show that it is possible to live through technological adolescence. . . . It is possible that the future of human civilization depends on the receipt of interstellar messages.

Chlorine is a deadly poison gas employed on European battlefields in World War I. Sodium is a corrosive metal which burns upon contact with water. Together they make a placid and unpoisonous material, table salt. Why each of these substances has the properties it does is a subject called chemistry.

She had studied the universe all her life, but had overlooked its clearest message: For small creatures such as we the vastness is bearable only through love.
Carl Sagan
Image
The Big Bang is our modern scientific creation myth. It comes from the same human need to solve the cosmological riddle [Where did the universe come from?]
Carl Sagan

When you make the finding yourself - even if you're the last person on Earth to see the light - you'll never forget it.
Carl Sagan

we make our world significant by the courage of our questions and the depth of our answers

The cure for a fallacious argument is a better argument, not the suppression of ideas.
Carl Sagan

It is the tension between creativity and skepticism that has produced the stunning and unexpected findings of science.

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.

I think the discomfort that some people feel in going to the monkey cages at the zoo is a warning sign.

First rule in government spending: why build one when you can have two at twice the price?

The beauty of a living thing is not the atoms that go into it, but the way those atoms are put together.

If we continue to accumulate only power and not wisdom, we will surely destroy ourselves.

Our loyalties are to the species and the planet. We speak for Earth.
