I'd like the [Cosmos] series to be so visually stimulating that somebody who isn't even interested in the concepts will just watch for the effects. And I'd like people who are prepared to do some thinking to be really stimulated.

When you look more generally at life on Earth, you find that it is all the same kind of life. There are not many different kinds there's only one kind. It uses about fifty fundamental biological building blocks, organic molecules.

If I finish a book a week, I will read only a few thousand books in my lifetime, about a tenth of a percent of the contents of the greatest libraries of our time. The trick is to know which books to read.

The visions we offer our children shape the future. It _matters_ what those visions are. Often they become self-fulfilling prophecies. Dreams are maps.

Carl Sagan
Image
History is full of people who out of fear, or ignorance, or lust for power has destroyed knowledge of immeasurable value which truly belongs to us all. We must not let it happen again.
Carl Sagan
Image
The Bill of Rights decoupled religion from the state, in part because so many religions were steeped in an absolutist frame of mind - each convinced that it alone had a monopoly on the truth and therefore eager for the state to impose this truth on others.
Carl Sagan
Image
Imagination will often carry us to worlds that never were. But without it we go nowhere.
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.

If the constellations had been named in the twentieth century, I suppose we would see bicycles and refrigerators in the sky.

I am often amazed at how much more capability and enthusiasm for science there is among elementary school youngsters than among college students.

War is murder writ large.

I would love to believe that when I die I will live again, that some thinking, feeling, remembering part of me will continue.

Absolute certainty will always elude us. We will always be mired in error. The most each generation can hope for is to reduce the error. . . .

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