The Metaphysical and the Physical Unite

The world to which our brains are adapted is actually the world of chaos and order. You can think about it as unexplored and explored territory too. When you encounter something unknown, you orient towards it. And that's an involuntary response - part of what orients you very rapidly towards predators so they don't kill you before you have a chance to respond. The reaction is first terror with perhaps an overlay of disgust and second curiosity.
