“It takes a fearless, unflinching love and deep humility to accept the universe as it is. The most effective way he knew to accomplish that, the most powerful tool at his disposal, was the scientific method, which over time winnows out deception. It can't give you absolute truth because science is a permanent revolution, always subject to revision, but it can give you successive approximations of reality.”

“And what greater might do we possess as human beings than our capacity to question and to learn?”

“The aspirations of democracy are based on the notion of an informed citizenry, capable of making wise decisions. The choices we are asked to make become increasingly complex. They require the longer-term thinking and greater tolerance for ambiguity that science fosters. The new economy is predicated on a continuous pipeline of scientific and technological innovation. It can not exist without workers and consumers who are mathematically and scientifically literate. ”

“Ten long trips around the sun since I last saw that smile, but only joy and thankfulness that on a tiny world in the vastness, for a couple of moments in the immensity of time, we were one.”

“I've been thinking about the distorted view of science that prevails in our culture. I've been wondering about this, because our civilization is completely dependent on science and high technology, yet most of us are alienated from science.”

“Even if it's very late at night. Someone's always awake in the world. But of all those things you could think up for people to be doing, I think going hungry would have to be your safest bet. Going hungry, pushing each other around, leaving bombs, breaking promises, leaving nothing. It happens far away all the time. But sometimes near. We're almost two kinds of people. Some of us see it on the evening news or read about it in the morning paper. And some of us get hurt. But, you know we all get hurt. Because even if you live in a very nice house like I do, sooner or later the lies and the fires have got to burn you.”

“As I looked out at the glittering waters of the Pacific I was seeing for Carl. He knew that it's not for any one generation to see the completed picture. That's the point. The picture is never completed. There is always so much more that remains to be discovered.”

“If you are searching for sacred knowledge and not just a palliative for your fears, then you will train yourself to be a good skeptic.”

“Science has carried us to the gateway to the universe. And yet our conception of our surroundings remains the disproportionate view of the still-small child. We are spiritually and culturally paralyzed, unable to face the vastness, to embrace our lack of centrality and find our actual place in the fabric of nature. We batter this planet as if we had someplace else to go. That we even do science is a hopeful glimmer of mental health. However, it's not enough merely to accept these insights intellectually while we cling to a spiritual ideology that is not only rootless in nature but also, in many ways, contemptuous of what is natural.”

“In the vastness of space and the immensity of time, it is my joy to share a planet and an epoch with Annie.[Dedication to Sagan's wife, Ann Druyan, in Cosmos]”
