Quotes | By

The following are quotes:

“Our sun is a second- or third-generation star. All of the rocky and metallic material we stand on, the iron in our blood, the calcium in our teeth, the carbon in our genes were produced billions of years ago in the interior of a red giant star. We are made of star-stuff.”
— Carl Sagan (1973), The Cosmic Connection: An Extraterrestrial Perspective[2]
“I am a collection of water, calcium, and organic molecules called Carl Sagan. You are a collection of almost identical molecules with a different collective label. But is that all? Is there nothing in here but molecules? Some people find this idea somehow demeaning to human dignity. For myself, I find it elevating that our universe permits the evolution of molecular machines as intricate and subtle as we are. But the essence of life is not so much the atoms and simple molecules that make us up as the way in which they are put together.”
— Carl Sagan (1980), Cosmos (§:Episode 5) (42:20-)[3]; compare: Wilhelm Ostwald (1926)
“We are star stuff harvesting star light.”
— Carl Sagan (1980), “Who Speaks for Earth”, TV episode[4]
“I am not an atheist. An atheist is someone who has compelling evidence that there is no Judeo-Christian-Islamic god. I am not that wise, but neither do I consider there to be anything approaching adequate evidence for such a god. Why are you in such a hurry to make up your mind? Why not simply wait until there is compelling evidence?”
— Carl Sagan (1996), “To Robert Pope”, Oct 2
