The physical nature of a book is such that it can become a power object for a Castanedan. But more often it is the obsession possession of a fool.
The physical nature of reality is misleading; human creatures are not creatures of reality, but of being. What is the difference?
Imagine a pain in the ball of your foot. You are certain it has a real, physical cause, because you feel physical pain.
But, you have it MRI'd and find out there is no cause in the foot. Now, you could argue that there is a damaged nerve ending or a busted synapse somewhere in between the foot and your brain, or even that the chemicals in the brain itself are out of balance. But you feel it in your foot! That alone is enough to demonstrate the mistake of your perception.
If we can become mistaken about something as basic and personal as a feeling of pain, what of things we see? It is the old philosophical problem of induction. We assume the sun is up when the alarm goes off, because it was up yesterday when the alarm went off. Better check.
