Mistrust is the fuel for so much mental pain, so many mental disorders. I am not talking here about the suspicions we sometimes have of one another, the distant but lurking sense that perhaps our lover lies to us, our best friend whispers behind our back. I am talking about a belief that betrayal inundates the atoms of the universe, is so woven into the workings of the world that every step is treacherous, and that below the rich mud lies a mine.
