“Hope is faith holding out its hand in the dark.”

“Doubt is the beginning, not the end, of wisdom.”

“Whoever ceases to be a student has never been a student.”

“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.”

“Because I expected so little, Gaines's painting is startlingly powerul. A lank-haired blond woman with a hard face sits at akitchen table in the harsh light of a bare bulb. She's surrounded by dirty cereal bowls and fast-food bags, and her shirt is open to the waist, revealing small sagging breasts. Her hollow eyes look out from the canvas with the sullen resignation of an animal that has helped build its own cage.”

“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.”

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.”
