More quotes by Carl Sagan
One of the great commandments of science is: 'Mistrust arguments from authority.'
Carl Sagan
The universe is not required to be in perfect harmony with human ambition.
Carl Sagan
The vast distances that separate the stars are providential. Beings and worlds are quarantined from one another. The quarantine is lifted only for those with sufficient self-knowledge and judgment to have safely traveled from star to star.
Carl Sagan
Humans - who enslave, castrate, experiment on, and fillet other animals - have had an understandable penchant for pretending animals do not feel pain.
Carl Sagan
He didn't want to believe. He wanted to know.
Carl Sagan
Across the sea of space, the stars are other suns.
Carl Sagan
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
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
There is in this Universe much of what seems to be design.
Carl Sagan
By exploring other worlds we safeguard this one. By itself, I think this fact more than justifies the money our species has spent in sending ships to other worlds. It is our fate to live during one of the most perilous and, at the same time, one of the most hopeful chapters in human history.
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
Think of how many religions attempt to validate themselves with prophecy. Think of how many people rely on these prophecies, however vague, however unfulfilled, to support or prop up their beliefs. Yet has there ever been a religion with the prophetic accuracy and reliability of science? ... No other human institution comes close.
Carl Sagan
You could just as well say that an agnostic is a deeply religious person with at least a rudimentary knowledge of human fallibility.
Carl Sagan
If the greenhouse effect is a blanket in which we wrap ourselves to keep warm, nuclear winter kicks the blanket off.
Carl Sagan
But I could be wrong.
Carl Sagan
Knowing a great deal is not the same as being smart intelligence is not information alone but also judgement, the manner in which information is coordinated and used.
Carl Sagan
Those with the courage to explore the weave and structure of the Cosmos, even where it differs profoundly from their wishes and prejudices, will penetrate its deepest mysteries.
Carl Sagan
We've arranged a civilization in which most crucial elements profoundly depend on science and technology.
Carl Sagan
Personally, I would be delighted if there were a life after death, especially if it permitted me to continue to learn about this world and others, if it gave me a chance to discover how history turns out.
Carl Sagan
And you are made of a hundred trillion cells. We are, each of us, a multitude.
Carl Sagan
