The first question they ask is: "Why was he eternally surprised?"And they were told: "Wen considered the nature of time and understood the universe is, instant by instant, re-created anew. Therefore, he understood, there is, in truth, no Past, only a memory of the Past. Blink your eyes, and the world you see next did not exist when you closed them. Therefore, he said, the only appropriate state of mind is surprise. The only appropriate state of heart is joy. The sky you see now, you have never seen before. The perfect moment is now. Be glad of it.
Terry Pratchett
