I thought this book would delve into how the spirit world affected world history. And it touched on that, but only a little it seemed to me. It was really more a history of mankind's view of spirits and how, at different times in history, mankind interacted with spirits according to belief at the time. On a personal level, I now know I'm not weird for my interest in spirits and ghosts. That interest is as old as mankind. And with all the experimentation by people a lot more patient than I am, I believe there is evidence that spirits do exist. Those who wish to ignore that evidence and write everything off as "fraud," well, they've just reached their Boggle Threshold.
