To me, a mystery is like a magnet. Whenever there is something that’s unknown, it has a pull to it. If you were in a room and there was an open doorway, and stairs going down and the light just fell away, you’d be very tempted to go down there. When you only see a part, it’s even stronger than seeing the whole. The whole might have a logic, but out of its context, the fragment takes on a tremendous value of abstraction. It can become an obsession.
