On npr I listened to the author of 'The Master and his Emmisary. In this radio lab show he pointed at how the obvious split/bicameral mind was hiding its secrets in plain sight. While the left has close focus the right has the big picture. To me it is the reason that hypnosis even works on the autosomatic nervous system. The elusive why questions are answered. He does generalize in the larger sociologic civilization and may turn some of his converts around but overall it is ahead of its time making Freud a nonsense experience.
