"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."

"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 Cosmos
"Every aspect of Nature reveals a deep mystery and touches our sense of wonder and awe. Those afraid of the universe as it really is, those who pretend to nonexistent knowledge and envision a Cosmos centered on human beings will prefer the fleeting comforts of superstition. They avoid rather than confront the world. But those with the courage to explore the weave and structure of the Cosmos, even where it differs profoundly from their wishes and prejudices, will penetrate its deepest mysteries."
Carl Sagan Cosmos
"The world is so exquisite with so much love and moral depth, that there is no reason to deceive ourselves with pretty stories for which there's little good evidence. Far better it seems to me, in our vulnerability, is to look death in the eye and to be grateful every day for the brief but magnificent opportunity that life provides."
Carl Sagan
"If it can be destroyed by the truth, it deserves to be destroyed by the truth."
Carl Sagan
"The significance of our lives and our fragile planet is then determined only by our own wisdom and courage. We are the custodians of life's meaning. We long for a Parent to care for us, to forgive us our errors, to save us from our childish mistakes. But knowledge is preferable to ignorance. Better by far to embrace the hard truth than a reassuring fable. If we crave some cosmic purpose, then let us find ourselves a worthy goal."
Carl Sagan Pale Blue Dot: A Vision of the Human Future in Space
"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, they laughed at the Wright brothers. But they also laughed at Bozo the Clown."
Carl Sagan Broca's Brain: Reflections on the Romance of Science
"All over the world there are enormous numbers of smart, even gifted, people who harbor a passion for science. But that passion is unrequited. Surveys suggest that some 95 percent of Americans are scientifically illiterate. That’s just the same fraction as those African Americans, almost all of them slaves, who were illiterate just before the Civil War—when severe penalties were in force for anyone who taught a slave to read. Of course there’s a degree of arbitrariness about any determination of illiteracy, whether it applies to language or to science. But anything like 95 percent illiteracy is extremely serious."
Carl Sagan The Demon-Haunted World: Science as a Candle in the Dark
"Nevertheless, (Jefferson) believed that the habit of skepticism is an essential prerequisite for responsible citizenship. He argued that the cost of education is trivial compared to the cost of ignorance, of leaving government to the wolves. He taught that the country is safe only when the people rule."

"For small creatures such as we the vastness is bearable only through love."
Carl Sagan
"Books are like seeds. They can lie dormant for centuries and then flower in the most unpromising soil."
Carl Sagan Cosmos
"One glance at a book and you hear the voice of another person, perhaps someone dead for 1,000 years. To read is to voyage through time."
Carl Sagan
"The visions we offer our children shape the future. It _matters_ what those visions are. Often they become self-fulfilling prophecies. Dreams are maps."
Carl Sagan Pale Blue Dot: A Vision of the Human Future in Space
"In its encounter with Nature, science invariably elicits a sense of reverence and awe. The very act of understanding is a celebration of joining, merging, even if on a very modest scale, with the magnificence of the Cosmos. And the cumulative worldwide build-up of knowledge over time converts science into something only a little short of a trans-national, trans-generational meta-mind."
Carl Sagan The Demon-Haunted World: Science as a Candle in the Dark
"Might it be possible at some future time, when neurophysiology has advanced substantially, to reconstruct the memories or insight of someone long dead?... It would be the ultimate breach of privacy."
Carl Sagan Broca's Brain: Reflections on the Romance of Science
"I do not think it irresponsible to portray even the direst futures if we are to avoid them we must understand that they are possible. But where are the alternatives Where are the dreams that motivate and inspire We long for realistic maps of a world we can be proud to give to our children. Where are the cartographers of human purpose Where are the visions of hopeful futures of technology as a tool for human betterment and not a gun on hair trigger pointed at our heads"
Carl Sagan Pale Blue Dot: A Vision of the Human Future in Space
"Many of the dangers we face indeed arise from science and technology—but, more fundamentally, because we have become powerful without becoming commensurately wise. The world-altering powers that technology has delivered into our hands now require a degree of consideration and foresight that has never before been asked of us."
Carl Sagan Pale Blue Dot: A Vision of the Human Future in Space
"Each Voyager is itself a message. In their exploratory intent, in the lofty ambition of their objectives, in their utter lack of intent to do harm, and in the brilliance of their design and performance, these robots speak eloquently for us."
Carl Sagan Pale Blue Dot: A Vision of the Human Future in Space
"Science is an attempt, largely successful, to understand the world, to get a grip on things, to get hold of ourselves, to steer a safe course. Microbiology and meteorology now explain what only a few centuries ago was considered sufficient cause to burn women to death."
Carl Sagan The Demon-Haunted World: Science as a Candle in the Dark
"One of the saddest lessons of history is this: If we’ve been bamboozled long enough, we tend to reject any evidence of the bamboozle. We’re no longer interested in finding out the truth. The bamboozle has captured us. It’s simply too painful to acknowledge, even to ourselves, that we’ve been taken. Once you give a charlatan power over you, you almost never get it back."

"We are star stuff which has taken its destiny into its own hands."
