More quotes by Carl Sagan

Image
When you make the finding yourself - even if you're the last person on Earth to see the light - you'll never forget it.
Carl Sagan
Image
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
Image
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
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
Books break the shackles of time, proof that humans can work magic.
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
Religions are often state-protected nurseries of pseudoscience, although there's no reason why religions have to play that role. In a way, it's an artefact from times long gone.
Carl Sagan
Image
In Mozambique, the story goes, monkeys do not talk, because they know if they utter even a single word some man will come and put them to work.
Carl Sagan
Image
It is far better to grasp the universe as it really is than to persist in delusion, however satisfying and reassuring.
Carl Sagan
Image
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
Image
Except for fools and madmen, everyone knows that nuclear war would he an unprecedented human catastrophe.
Carl Sagan
Image
We are, each of us, a multitude. Within us is a little universe.
Carl Sagan
Image
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
Image
We are like butterflies who flutter for a day and think it is forever.
Carl Sagan
Image
The old appeals to racial, sexual and religious chauvinism to rabid nationalist fervor, are beginning not to work.
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
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
Image
Humans - who enslave, castrate, experiment on, and fillet other animals - have had an understandable penchant for pretending animals do not feel pain.
Carl Sagan
Image
The prediction of nuclear winter is drawn not, of course, from any direct experience with the consequences of global nuclear war, but rather from an investigation of the governing physics.

If you wish to make an apple pie from scratch, you must first invent the universe.
