I concur with many other commenters here, this is a fantastic read. Though, I find the value in this book is not the discrete proposals Jaynes makes - his conclusions on schizophrenia are dubious at best. Jayne’s achievement is in his explaining of the mindset and thought patterns (what Jaynes calls consciousness) of the ancients.

So often ancient man felt alien to me. Not until reading this book have I felt I understand what it was like to have lived millennia ago.
