More quotes by 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
There are more potential combinations of DNA [physical forms] than there are atoms in the universe.
Carl Sagan
The well-meaning contention that all ideas have equal merit seems to me little different from the disastrous contention that no ideas have any merit.
Carl Sagan
Books break the shackles of time, proof that humans can work magic.
Carl Sagan
In the long run, the aggressive civilizations destroy themselves, almost always. It's their nature. They can't help it.
Carl Sagan
Human history can be viewed as a slowly dawning awareness that we are members of a larger group.
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
An atheist is someone who is certain that God does not exist, someone who has compelling evidence against the existence of God. I know of no such compelling evidence.
Carl Sagan
We go about our daily lives understanding almost nothing of the world.
Carl Sagan
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
The Hindu religion is the only of the World's great faiths dedicated to the idea that the Cosmos itself undergoes an immense, indeed an infinite, number of deaths and rebirths.
Carl Sagan
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.
Carl Sagan
I worry that, especially as the Millennium edges nearer, pseudo-science and superstition will seem year by year more tempting, the siren song of unreason more sonorous and attractive.
Carl Sagan
If we ruin the earth, there is no place else to go
Carl Sagan
It is the responsibility of scientists never to suppress knowledge, no matter how awkward that knowledge is, no matter how it may bother those in power we are not smart enough to decide which pieces of knowledge are permissible, and which are not.
Carl Sagan
By looking far out into space we are also looking far back into time, back toward the horizon of the universe, back toward the epoch of the Big Bang.
Carl Sagan
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.
Carl Sagan
Books are key to understanding the world and participating in a democratic society.
Carl Sagan
Arguments from authority carry little weight – authorities have made mistakes in the past. They will do so again in the future. Perhaps a better way to say it is that in science there are no authorities at most, there are experts.
Carl Sagan
Any civilization that doesn't develop space travel dies.
