Dr. Stout has so much insight about life and psychology, even if you do not suffer from DID yourself, you will absorb something from this book. She really has a way with words, she writes in the first chapter that people who are commonly considered to be "sane" are a little nuts themselves. They are mostly unaware of their behaviors and walk around in a cognitive haze. couldn't agree more. I have read all three of her books and what I prefer about her over other authors, is that she goes beyond the obvious to find the truth. Everyone knows a rape victim or a war veteran has been traumatized, I am trying to devalue their experiences, but Dr. Stout also discusses people in domestic situations where the trauma is more latent and more deceptive. This book is really an eye-opener, I was surprised at how many people I would have written off as just being eccentric before I read this book, but would now consider more dangerous. This is really useful when choosing which parents you want to trust your kids around. She talks about how people in third world countries deal with the trauma of poverty and political chaos. She also discusses the possible dangers of someone who switches from different cognitive states who leads a nation. I immediately thought of Robert Mugabe, the president of Zimbabwe who began as a freedom fighter and later eroded into a brutal tyrant. Such an important timeless book, better than CSI and better than Dr. Laura and Dr. Phil.
