They (i. e., the Pythagoreans) did not advocate the free confrontation of conflicting points of view. Instead, like all orthodox religions, they practised a rigidity that prevented them from correcting their errors.

More quotes by 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
A celibate clergy is an especially good idea, because it tends to suppress any hereditary propensity toward fanaticism.
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
Don't judge everyone else by your own limited experience.
Carl Sagan
For all our failings, despite our limitations and fallibilities, we humans are capable of greatness.
Carl Sagan
The universe is a pretty big place. If it's just us, seems like an awful waste of space.
Carl Sagan
For all its material advantages, the sedentary life has left us edgy, unfulfilled, even after 400 generations in villages and cities, we haven't forgotten: The open road still softly calls like a nearly forgotten song of childhood.
Carl Sagan
To live in the hearts of others is to never die in those we leave behind.
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
It seems madness to say, 'We're worried that they're going to become addicted to marijuana' -- there's no evidence whatever that it's an addictive drug, but even if it were, these people are dying, what are we saving them from?
Carl Sagan
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?
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
We are made of starstuff.
Carl Sagan
We are star stuff harvesting sunlight.
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
Life is but a momentary glimpse of the wonder of this astonishing universe, and it is sad to see so many dreaming it away on spiritual fantasy.
Carl Sagan
In our time, we have sifted the sands of Mars, we have established a presence there, we have fulfilled a century of dreams!
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
Extraordinary claims demand extraordinary evidence
Carl Sagan
If the constellations had been named in the twentieth century, I suppose we would see bicycles and refrigerators in the sky.
