More quotes by Carl Sagan
Any faith that admires truth, that strives to know God, must be brave enough to accommodate the universe.
Carl Sagan
The Platonists and their Christian successors held the peculiar notion that the Earth was tainted and somehow nasty, while the heavens were perfect and divine. The fundamental idea that the Earth is a planet, that we are citizens of the Universe, was rejected and forgotten.
Carl Sagan
It is said that men may not be the dreams of the god, but rather that the gods are the dreams of men.
Carl Sagan
There is much that science doesn't understand, many mysteries still to be resolved. In a Universe tens of billions of light-years across and some ten or fifteen billion years old, this may be the case forever. We are constantly stumbling on new surprises
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
Science is a way to call the bluff of those who only pretend to knowledge. It is a bulwark against mysticism, against superstition, against religion misapplied to where it has no business being.
Carl Sagan
The method of science is tried and true. It is not perfect, it's just the best we have. And to abandon it, with its skeptical protocols, is the pathway to a dark age.
Carl Sagan
I set before you two ways: You can use your technology to destroy yourselves or to carry you to the planets and the stars. It's up to you.
Carl Sagan
It is far better to grasp the universe as it really is than to persist in delusion, however satisfying and reassuring.
Carl Sagan
I believe that in every person is a kind of circuit which resonates to intellectual discovery-and the idea is to make that resonance work
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
Recent research shows that many children without enough to eat wind up with diminished capacity to understand and learn (“cognitive impairment” ). Children don't have to be starving for this to happen. Even mild undernourishment — the kind most common among poor people in America — can do it.
Carl Sagan
Somewhere, something incredible is waiting to be known.
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
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
In a complex universe, in a society undergoing unprecedented change, how can we find the truth if we are not willing to question everything and to give a fair hearing to everything?
Carl Sagan
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.
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.
Carl Sagan
Imagine we could accelerate continuously at 1 g-what we're comfortable with on good old terra firma-to the midpoint of our voyage, and decelerate continuously at 1 g until we arrive at our destination. It would take a day to get to Mars, a week and a half to Pluto, a year to the Oort Cloud, and a few years to the nearest stars.
Carl Sagan
There are more potential combinations of DNA [physical forms] than there are atoms in the universe.
Carl Sagan
