Top 29 Sagan Quotes & Sayings

In the 1970s, we had Carl Sagan, and he was so suave with his turtleneck and his tweed jacket. And he was, you know, he made science look cool. And in punk rock, we haven't had that. We haven't had the Carl Sagan of punk.

I agree, along with Carl Sagan, that we should eventually become a two planet species. Life is too precious to place on a single planet.

Interviewer: "Didn't [Sagan] want to believe?" Druyan: "He didn't want to believe. He wanted to know.

Coal, oil and gas are called fossil fuels, because they are mostly made of the fossil remains of beings from long ago. The chemical energy within them is a kind of stored sunlight originally accumulated by ancient plants. Our civilization runs by burning the remains of humble creatures who inhabited the Earth hundreds of millions of years before the first humans came on the scene. Like some ghastly cannibal cult, we subsist on the dead bodies of our ancestors and distant relatives. - Dr. Carl Sagan

Scientists tend to come in two stripes: those who have tremendous appetite and aptitude for the details, and those who illuminate the big picture. Sagan was definitely in the latter category, and he was profoundly good at it. He made connections that others did not have the intellectual breadth or courage to make.

The disturbing truth about science communication is that we have theories and ways of delivering messages that really are like putting a candle to the dark, as Carl Sagan would say. We aren't sure what will work, when, or how much. But for all that uncertainty, that doesn't mean we shouldn't try.

I met Carl Sagan quite a few times - a fantastic and amazing person. I love him. Neil deGrasse Tyson is a good friend, too.

Mythology is about Good VS Evil, is it not? We can pretend runes and astrology and reading tea leaves...But to whom do we pray when we are terrified? Carl Sagan's essays?

I remember that one time Carl Sagan was giving a talk, and he spelled out, in a kind of withering succession, these great theories of demotion that science has dealt us, all of the ways in which science is telling us we are not who we would like to believe we are. At the end of it, a young man came up to him and he said: "What do you give us in return? Now that you've taken everything from us? What meaning is left, if everything that I've been taught since I was a child turns out to be untrue?" Carl looked at him and said, Do something meaningful.

It turns out one of my dad's best friends was Carl Sagan when I was little. They were both Harvard professors.

If Francoise Sagan hadn't written a book called A Chateau in Sweden, I would certainly write a short story called A Chateau in Puerto Rico. And I may yet.

Carl Sagan spoke fluently between biology and geology and astrophysics and physics. If you move fluently across those boundaries, you realize that science is everywhere; science is not something you can step around or sweep under the rug.

The book that blew the doors off the house, grabbing me with its breathtakingly deep and irresistible view of the universe and our relation to it, was 'Intelligent Life in the Universe' by I. S. Shklovskii and Carl Sagan. I recall an enchanting all-nighter completing a college homework assignment to read the first chapter.

As my old professor Carl Sagan said so often, 'When you’re in love, you want to tell the world.’ And I base my beliefs on the information and the process that we call science. It fills me with joy to make discoveries every day of things I’ve never seen before. It fills me with joy to know that we can pursue these answers. It is an astonishing thing that we are — you and I are one of the ways the universe knows itself.

If you look up at the Milky Way through the eyes of Carl Sagan, you get a feeling in your chest of something greater than yourself. And it is. But it's not supernatural.

Carl Sagan always used to say that when he was trying to explain something to someone, he would go back to that time when he didn't understand it, and then he would retrace his thought steps so that he could make it absolutely clear, and that's one of the infinite number of things I learned from him.

I want Carl Sagan to explain the sky to me.

'Carl Sagan: A Life,' though a riveting tale, tells as much about the all-too-human feelings of jealousy and resentment as it does about the individual who inspired them.

I think I set myself on a course to become a scientist around about the time that Carl Sagan's 'Cosmos' series was on television, and there really was no going back for me at that point, and then I went on to study space science and then get my Ph.D., then go aboard and work in the European Space Agency.

My mom was a high school science teacher for decades. She just never made it feel like we had to choose between the arts and the sciences. We had bookshelves full of novels, and she also had Rachel Carson and Aldo Leopold and Carl Sagan.

By all means let's be open-minded, but not so open-minded that our brains drop out. -this quote is actually found in Carl Sagan's book The Demon Haunted World: Science as a Candle in the Dark, where he attributes it to engineer James Oberg, who says he stole it from someone else.

The issue, as correctly emphasized by Carl Sagan, is the probability of the evolution of high intelligence and an electronic civilization on an inhabited world. Once we have life (and almost surely it will be very different from life on Earth), what is the probability of its developing a lineage with high intelligence? On Earth, among millions of lineages of organisms and perhaps 50 billion speciation events, only one led to high intelligence; this makes me believe in its utter improbability.

I want the strangeness and weirdness and incomprehensibility of life that art can reflect so well, but I want it to feel like a mystery that is inviting us in. Sagan's great art lesson for me was generosity of wonder and making curiosity contagious.

When I was in my teens, Yehudi Menuhin, who was at work on his project 'The Music of Man,' introduced me to the great astronomer Carl Sagan. It was Sagan who first opened my eyes to the magnitude of the universe, and essentially to the notion of 'music of the spheres.'

My general impression about people like Steve Gould and Carl Sagan and so on is that when they disappear as individuals and are no longer appearing on the stage and they are no longer writing, that their lifetime of acknowledgement by the general reading public is not very long... There were many people in the 19th century who were equally famous people who gave working man's lectures, supporters of Darwin, we as scholars know their names but the general public never heard of them.

Carl Sagan's 'Pale Blue Dot' is where I got the title 'Momentary Masters.'

By my reckoning, I'm about 100 kilometers from Pathfinder. Technically it's called “Carl Sagan Memorial Station.” But with all due respect to Carl, I can call it whatever the hell I want. I'm the King of Mars.

The past history of human belief is a cautionary tale. We have killed thousands of our fellow human beings because we believed they had signed a contract with the devil, and had become witches. We still kill more than a thousand people each year for witchcraft. In my view, there is only one hope for humankind to emerge from what Carl Sagan called "the demon-haunted world" of our past. That hope is science.

The true scientific understanding of the nature of existence is so utterly fascinating; how could you not want people to share it? Carl Sagan, I think, said 'when you're in love, you want to tell the world.' And who, on understanding a scientific view of reality, would not, as it were, fall in love and want to tell the world.
