Query: A real light into the darkness of madness

I read this book almost two decades ago and I just read it again. This is a book that deserves several readings. Sass has given us analogies to the understanding of madness that we can, for once, actually look at...opening up a new road to understanding "modern art" and chronic mental illness. Since madness is always a broken, puzzling departure from what is considered "normal"; a visual representation of this extremely personal and in most cases incomprehensible reality is very welcome. Louis Sass has given us a whole new starting point on a new psychic road map.
