Carl Sagan quotes about our place in the universe
1.) “Somewhere, something incredible is waiting to be known.” – Carl Sagan
2.) “Every one of us is, in the cosmic perspective, precious. If a human disagrees with you, let him live. In a hundred billion galaxies, you will not find another.”– Carl Sagan
3.) “The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies was made in the interiors of collapsing stars. We are made of star stuff.” – Carl Sagan
4.) “Science is not only compatible with spirituality; it is a profound source of spirituality.” – Carl Sagan
5.) “A book is made from a tree. It is an assemblage of flat, flexible parts (still called “leaves”) imprinted with dark pigmented squiggles. One glance at it and you hear the voice of another person, perhaps someone dead for thousands of years.
Across the millennia, the author is speaking, clearly and silently, inside your head, directly to you. Writing is perhaps the greatest of human inventions, binding together people, citizens of distant epochs, who never knew one another. Books break the shackles of time ― proof that humans can work magic.”
– Carl Sagan
6.) “For me, it is far better to grasp the Universe as it really is than to persist in delusion, however satisfying and reassuring.” – Carl Sagan
7.) “Extraordinary claims require extraordinary evidence.” – Carl Sagan
8.) “Who is more humble? The scientist who looks at the universe with an open mind and accepts whatever the universe has to teach us, or somebody who says everything in this book must be considered the literal truth and never mind the fallibility of all the human beings involved?” – Carl Sagan
9.) “In science it often happens that scientists say, ‘You know that’s a really good argument; my position is mistaken,’ and then they would actually change their minds and you never hear that old view from them again. They really do it.
It doesn’t happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.”
– Carl Sagan
10.) “Imagination will often carry us to worlds that never were, but without it we go nowhere.” – Carl Sagan

11.) “It pays to keep an open mind, but not so open your brains fall out.” – Carl Sagan
12.) “I would love to believe that when I die I will live again, that some thinking, feeling, remembering part of me will continue. But as much as I want to believe that, and despite the ancient and worldwide cultural traditions that assert an afterlife, I know of nothing to suggest that it is more than wishful thinking.” – Carl Sagan
13.) “But the fact that some geniuses were laughed at does not imply that all who are laughed at are geniuses. They laughed at Columbus, they laughed at Fulton, and they laughed at the Wright brothers. But they also laughed at Bozo the Clown.” – Carl Sagan
14.) “We can judge our progress by the courage of our questions and the depth of our answers, our willingness to embrace what is true rather than what feels good.” – Carl Sagan
15.) “We are like butterflies that flutter for a day and think it is forever.” – Carl Sagan
16.) “The universe is a pretty big place. If it’s just us, seems like an awful waste of space.” – Carl Sagan
17.) “You’re an interesting species. An interesting mix. You’re capable of such beautiful dreams, and such horrible nightmares. You feel so lost, so cut off, so alone, only you’re not. See, in all our searching, the only thing we’ve found that makes the emptiness bearable, is each other.” – Carl Sagan
18.) “Frederick Douglass taught that literacy is the path from slavery to freedom. There are many kinds of slavery and many kinds of freedom, but reading is still the path.” – Carl Sagan
19.) “How is it that hardly any major religion has looked at science and concluded, ‘This is better than we thought! The Universe is much bigger than our prophets said, grander, more subtle, more elegant?’ Instead they say, ‘No, no, no! My god is a little god, and I want him to stay that way.’ A religion, old or new, that stressed the magnificence of the Universe as revealed by modern science might be able to draw forth reserves of reverence and awe hardly tapped by the conventional faiths.” – Carl Sagan
20.) “The nuclear arms race is like two sworn enemies standing waist deep in gasoline, one with three matches, the other with five.” – Carl Sagan
Carl Sagan quotes about life and faith
21.) “The truth may be puzzling. It may take some work to grapple with. It may be counterintuitive. It may contradict deeply held prejudices. It may not be consonant with what we desperately want to be true. But our preferences do not determine what’s true.” – Carl Sagan
22.) “For small creatures such as we the vastness is bearable only through love.” – Carl Sagan
23.) “Extinction is the rule. Survival is the exception.” – Carl Sagan

28.) “If we long to believe that the stars rise and set for us, that we are the reason there is a Universe, does science do us a disservice in deflating our conceits?” – Carl Sagan
29.) “We have also arranged things so that almost no one understands science and technology. This is a prescription for disaster. We might get away with it for a while, but sooner or later this combustible mixture of ignorance and power is going to blow up in our faces.” – Carl Sagan
30.) “The universe seems neither benign nor hostile, merely indifferent.” – Carl Sagan
Carl Sagan quotes about humanity

42.) “But I try not to think with my gut. If I’m serious about understanding the world, thinking with anything besides my brain, as tempting as that might be, is likely to get me into trouble.” – Carl Sagan
43.) “Our species needs, and deserves, a citizenry with minds wide awake and a basic understanding of how the world works.” – Carl Sagan

45.) “If God is omnipotent and omniscient, why didn’t he start the universe out in the first place so it would come out the way he wants? Why’s he constantly repairing and complaining?

He’d be out of business, if there was any competition.” – Carl Sagan
