"You mean," said Lucy rather faintly, "that it would have turned out all right - somehow? But how? Please, Aslan! Am I not to know?"
"To know what would have happened, child?" said Aslan. "No. Nobody is ever told that."
- C.S. Lewis, Prince Caspian
Have you ever wondered what might happen if you could hear everything people ever said about you? Or thought that life would be simpler if everyone in it came with an instruction manual? What if you knew what you were going to be when you grew up from gradeschool on? What if the person you were going to marry had a little red heart floating over their head that said "I'm the one!" and light-up maps showed us where we would live and travel?
What if we could know what might have happened if we'd made a phone call to a particular person, or said something differently during a conversation? It might take a lot of the adventure and spontanaeity out of life to know this stuff, and it might save a lot of confusion and embarassment. But what if a book showed up on your doorstep that contained all that information. Would you open it?
Would you really want to know?
