“Sooner or later. It had better be sooner. Later is like the horizon; it recedes as you approach.”

“Thought like that showed me the needless ambiguity of words like space-time. The average person heard a word like that and figured he'd never understand it. But it was so simple. Every place you ever saw was linked to a specific time ... the school you visited twenty years after you graduated, the football field you played on, the track you ran -- none of them was the same. If they were, you would collide with the generations that had run on them before and after you. The lover you kissed was not the same person he or she was sixty seconds before. In that minute, a million skin cells had died and been replaced by new ones. The smallest slices of space-time separated thought from action Life from death.”

“I listened in amazement. You saw a face on an American street, or in an office, and you had no idea that a tragic epic lay behind it.”

“My favorite book is The Mysterious Island. I order my books from a flimsy catalog the teacher hands out to every student in the class. Emil and the Detectives. White Fang. Like that. Money is tight for us, but when it comes to books my mother is a spendthrift; I can order as many as I like. I sit here day after day, waiting for my books to arrive. My books. It takes a month or more, but when they finally do, when the teacher opens the big box and passes out the orders to the kids, checking the books against a form taken from her desk, I glow with happiness. I've never had the newest dress, or the prettiest, but I always have the tallest stack of books. Little paperbacks that smell of wet ink. I lay my cheek against their cool covers, anticipating the stories inside, knowing all the other girls wonder what I could possibly want with those books.”

“The temptation to second-guess is strong. But I must remember one thing. Life is simple.You are healthy or you are sick. You are faithful to your wife or you aren't. You are alive or you are dead. I am alive.”

“Just because you will not see the work completed does not mean you are free not to take it up.”

“He always reminded us that every atom in our bodies was once part of a distant star that had exploded. He talked about how evolution moves from simplicity toward complexity, and how human intelligence is the highest known expression of evolution. I remember him telling me that a frog's brain is much more complex than a star. He saw human consciousness as the first neuron of the universe coming to life and awareness. A spark in the darkness, waiting to spread to fire.”
