McFadden's electromagnetic theory of consciousness may seem far out to some readers. It may well be wrong. But there is one thing I'm certain of: the eventual true explanation of consciousnessness will be astonishing and strange, for if it fit easily with existing knowledge, the mystery would have been solved years ago.
Note: In a response(pdf) to a review of the McFadden book by Matthew Donald(pdf),
McFadden and his collaborator, Jim Al-Khalili, reference the work of the physicist, Eric Heller, who is also known as Rick Heller. I am a different Rick Heller(the two of us are in a constant battle on Google, along with some guy who sells flutes shaped like a duck, to be the Rick Heller ;-: ).
