More quotes by Carl Sagan
Exploration is in our nature. We began as wanderers, and we are wanderers still. We have lingered long enough on the shores of the cosmic ocean. We are ready at last to set sail for the stars.
Carl Sagan
Whatever the reason you're on Mars, I'm glad you're there, and I wish I was with you.
Carl Sagan
If chimpanzees have consciousness, if they are capable of abstractions, do they not have what until now has been described as 'human rights'? How smart does a chimp have to be before killing him constitutes murder?
Carl Sagan
The universe seems neither benign nor hostile, merely indifferent.
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
When you look more generally at life on Earth, you find that it is all the same kind of life. There are not many different kinds there's only one kind. It uses about fifty fundamental biological building blocks, organic molecules.
Carl Sagan
In the vastness of the Cosmos there must be other civilizations far older and more advanced than ours.
Carl Sagan
We are an intelligent species and the use of our intelligence quite properly gives us pleasure. In this respect the brain is like a muscle. When we think well, we feel good. Understanding is a kind of ecstasy.
Carl Sagan
Science is a way of thinking much more than it is a body of knowledge.
Carl Sagan
We are star stuff which has taken its destiny into its own hands.
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
The nuclear arms race is like two sworn enemies standing waist deep in gasoline, one with three matches, the other with five.
Carl Sagan
We are the custodians of life's meaning.
Carl Sagan
A new consciousness is developing which sees the earth as a single organism and recognizes that an organism at war with itself is doomed. We are one planet.
Carl Sagan
Except for fools and madmen, everyone knows that nuclear war would he an unprecedented human catastrophe.
Carl Sagan
Writing is perhaps the greatest of human inventions, binding together people who never knew each other, citizens of distant epochs. Books break the shackles of time. A book is proof that humans are capable of magic.
Carl Sagan
We are star stuff harvesting sunlight.
Carl Sagan
We are made of starstuff.
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
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
