This book is a really good example of "bait and switch" argumentation. He gets you going on things that are true and then quickly supplants it with a complete non-sequitur. Two examples: magnetic force is one of the 4 forces we know of, yadda-yadda (stuff that is scientifically proven) and then...so that's why some people can bend spoons (because they have greater magnetic force than others).
Another one: we know photons exist, they are without mass, yada-yada (says things that are scientifically proven) and then...so angels are beings made out of light, have no mass, because photons exist and angels are basically photons (massless entities of light) that means that angels exist too.
Interesting read, faulty logic, logically invalid conclusions drawn.
