More quotes by Carl Sagan
If we do not speak for Earth, who will? If we are not committed to our own survival, who will be?
Carl Sagan
I also wish that the Pledge of Allegiance were directed at the Constitution and the Bill of Rights, as it is when the President takes his oath of office, rather than to the flag and the nation
Carl Sagan
In the fabric of space and in the nature of matter, as in a great work of art, there is, written small, the artist's signature.
Carl Sagan
We are a way for the cosmos to know itself.
Carl Sagan
The desire to be connected with the cosmos reflects a profound reality, but we are connected not in the trivial ways that astrology promises, but in the deepest ways.
Carl Sagan
The fact is that far more crime and child abuse has been committed by zealots in the name of God, Jesus and Mohammed than has ever been committed in the name of Satan. Many people don’t like that statement, but few can argue with it.
Carl Sagan
We are, in the most profound sense, children of the Cosmos.
Carl Sagan
Scientists make mistakes. Accordingly, it is the job of the scientist to recognize our weakness, to examine the widest range of opinions, to be ruthlessly self-critical. Science is a collective enterprise with the error-correction machinery often running smoothly.
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 open road still softly calls, like a nearly forgotten song of childhood
Carl Sagan
That we can now think of no mechanism for astrology is relevant but unconvincing. No mechanism was known, for example, for continental drift when it was proposed by Wegener. Nevertheless, we see that Wegener was right, and those who objected on the grounds of unavailable mechanism were wrong.
Carl Sagan
One trend that bothers me is the glorification of stupidity, that the media is reassuring people it's alright not to know anything. That to me is far more dangerous than a little pornography on the Internet.
Carl Sagan
I believe our future depends powerfully on how well we understand this cosmos in which we float, like a mote of dust in the morning sky.
Carl Sagan
If we're capable of conjuring up terrifying monsters in childhood, why shouldn't some of us, at least on occasion, be able to fantasize something similar, something truly horrifying, a shared delusion, as adults?
Carl Sagan
Our ancestors lived out of doors. They were as familiar with the night sky as most of us are with our favorite television programs.
Carl Sagan
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. . . .
Carl Sagan
Whatever the reason you're on Mars, I'm glad you're there, and I wish I was with you.
Carl Sagan
Better the hard truth, I say, than the comforting fantasy. And in the final tolling it often turns out that the facts are more comforting than the fantasy.
Carl Sagan
The nuclear arms race is like two sworn enemies standing waist deep in gasoline, one with three matches, the other with five.
Carl Sagan
Humans are very good at dreaming, although you'd never know it from your television.
Carl Sagan
