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.
I don’t know where I’m going, but I’m on my way.
We live in a society absolutely dependent on science and technology, and yet have cleverly arranged things so that almost no one understands science and technology. That’s a clear recipe for disaster.
Not only could nobody tell me, but nobody even had the sense that it was an interesting question. They looked at me funny. I asked my parents; I asked my parents’ friends; I asked other adults. None of them knew. My mother said to me, “Look, we’ve just got you a library card. Take it, get on the streetcar, go to the New Utrecht branch of the New York Public Library, get out a book and find the answer.”

I would love to believe that when I die I will live again, that some thinking, feeling, remembering part of me will continue. But 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.
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.
“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, 1987 CSICOP Keynote Address
“The surface area of Mars is exactly as large as the land area of the Earth. A thorough reconnaissance will clearly occupy us for centuries. But there will be a time when Mars is all explored; a time after robot aircraft have mapped it from aloft, a time after rovers have combed the surface, a time after samples have been returned safely to Earth, a time after human beings have walked the sands of Mars. What then? What shall we do with Mars?”
~ Carl Sagan, in Chapter V of Cosmos, titled ‘Blues for a Red Planet’
