Author: Julian Jaynes
Proposes that human brains existed in a bicameral state until as recently as 3000 years ago and that consciousness as we know it was a subsequent development. This controversial theory has been called "either complete rubbish or consumate genius."
Good - This book has been used, but it is still in a clean condition. There should be no brown spots, but do expect slight yellowing or some writings on the pages.
