The Origin of Consciousness if the Breakdown of the Bicameral Mind by Julian Jaynes. Mindblowing book, changes EVERYTHING. Has anyone read it? I had a professor that let me borrow it. It was amazing. I've yet to find anyone else that's read it though. Really heavy reading. Encyclopedias and dictionaries a must, cross referencing an excellent option. You can find it on Amazon. I bought a copy through the bookstore I worked at, also found an original print at a used booksale. READ THIS BOOK IF YOU READ NO OTHER IN THE REST OF YOUR LIFETIME.
