This book contains a lot of heavy science. It's good to see a scientific type take this subject so seriously, even if the author is a social scientist. With my humanities degrees, I can't say I understood every word. But, humanities teaches you to look at the big picture and I do believe I came away with an overall understanding of what the author was talking about. It's basically a unified theory of the paranormal, which is what I believe in, with the author using dark matter and particle physics as the glue to unify his theory.
A couple of parts I thought were interesting was the observation that our society will arrest and convict someone based on eye witness testimony, yet thousands of cryptid sightings -and especially Bigfoot sightings - even when investigated by trained investigators are dismissed as being the result of the psychological problems of "crazy" people or the rantings of alcohol abusers. This really hit me hard. Also, the meaning of "para" as in "paranormal" is often assumed to mean something crazy. Yet, "para" simply means "next to," like a paramedic kneeling down close to a patient. There is nothing inherently wacky or crazy about the paranormal as it simply refers to things that exist right alongside of us in our normal reality. Finally, there was the notion that some, if not all, cryptids may be superior to humans based on their ability to use physics to their advantage to control time and space for things like teleportation and cloaking.
Overall, this book added a lot to my knowledge and understanding of Fortean phenomena. It is a fine addition to the large amount of data I am synthesizing in an attempt to better understand the paranormal.
