Image
We live in an in-between universe where things change all right...but according to patterns, rules, or as we call them, laws of nature.
Carl Sagan
Image
A celibate clergy is an especially good idea, because it tends to suppress any hereditary propensity toward fanaticism.
Carl Sagan
Image
Looking at fires when high, by the way, especially through one of those prism kaleidoscopes which image their surroundings, is an extraordinarily moving and beautiful experience.
Carl Sagan
Image
We can't help it. Life looks for life.
Carl Sagan
Image
The immense distances to the stars and the galaxies mean that we see everything ins pace int he past, some as they were before the Earth came to be. Telescopes are time machines.
Carl Sagan
Image
The Universe forces those who live in it to understand it. Those creatures who find everyday experience a muddled jumble of events with no predictability, no regularity, are in grave peril. The Universe belongs to those who, at least to some degree, have figured it out.
Carl Sagan
Image
The universe seems neither benign nor hostile, merely indifferent.
Carl Sagan
Image
If the constellations had been named in the twentieth century, I suppose we would see bicycles and refrigerators in the sky.
Carl Sagan
Image
Any faith that admires truth, that strives to know God, must be brave enough to accommodate the universe.
Carl Sagan
Image
Modern Darwinism makes it abundantly clear that many less ruthless traits, some not always admired by robber barons and Fuhrers - altruism, general intelligence, compassion - may be the key to survival.
Carl Sagan
Image
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
Image
Science is a way of thinking much more than it is a body of knowledge.
Carl Sagan
Image
It does no harm to the romance of the sunset to know a little bit about it.
Carl Sagan
Image
We invest far off places with a certain romance... Long summers, mild winters, rich harvests, plentiful game none of them lasts for ever. Your own life, or your bands, or even your species - might be owed to a restless few, drawn by a craving they can hardly articulate or understand, to undiscovered lands, and new worlds.
Carl Sagan
Image
Our passion for learning ... is our tool for survival.
Carl Sagan
Image
One of the great commandments of science is: 'Mistrust arguments from authority.'
Carl Sagan
Image
Since, in the long run, every planetary society will be endangered by impacts from space, every surviving civilization is obliged to become spacefaring — not because of exploratory or romantic zeal, but for the most practical reason imaginable: staying alive.
Carl Sagan
Image
It's perilous and foolhardy for the average citizen to remain ignorant about global warming, say, or ozone depletion, air pollution, toxic and radioactive wastes, acid rain, topsoil erosion, tropical deforestation, exponential population growth. Jobs and wages depend on science and technology.
Carl Sagan
Image
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
Image
A millennium before Europeans were willing to divest themselves of the Biblical idea that the world was a few thousand years old, the Mayans were thinking of millions and the Hindus billions.
