I found it on this list:
Where also the following books some of which I read to (Vehicles is really good) can be found:
The White Goddess - Robert Graves
Graves' grammar of poetic myth works at so many levels at the same time that I can't keep track of them all. This is not a book, this is a neurosis you can borrow. Druidic power to the nerds.
The Origin of Consciousness in the Breakdown of the Bicameral Mind - Julian Jaynes
Never mind the bulky title. The theory of Jaynes seems preposterous at first: before man was conscious he would not stop and think when making a decision, instead he would literally hear a voice telling him what to do. When life became too complicated this faculty broke down, but not in an instant. Religion is a by-product of this neuro-catastrophe. Jaynes however knows to make use of historic material in such a way that in the course of his argument he becomes plausible! If you don't trust me on this, trust Daniel Dennett.
The Ghost of Chance - William S. Burroughs
Burroughs was a great admirer of Jaynes and here he uses the bicameral image of two dividing brain spheres as a metaphor for the divide between peaceful lemur on Madagascar and the war-mongering chimpanzee on the African mainland as a reminder that human evolution could have taken a better turn.
Ancient Evenings - Norman Mailer
This book, the only lengthy novel in this list, I first looked up because Burroughs referenced it as his inspiration for 'The Western Lands'. When I noticed it starts with my favourite Yeats quote I knew I needed to read this. Even though Burroughs could never have written it like this, at times it is more Burroughs then Burroughs himself. It is the autobiography of a Ka, the lowliest soul of the seven souls of the ancient Egyptians, which makes for unusual reading. Especially because Mailer uses an uncensored version of Egyptian mythology which, to put it mildly, differs from the version you get of it from the National Geographic. The Egyptians practised sex magic with the stamina of a bonobo. Mailer makes Aleister Crowley look like a prudish schoolboy. This is the boldest attempt to recreate a radically different mind from ours that I know of, and does so successfully. The novel as the creation of an artificial consciousness. At the same time it doubles as an All American Novel (yuk).
The Mind in the Cave - David Lewis-Williams
Palaeolithic Psychedelia anyone? Close your eyes, place a finger on both of your eyelids and press gently. What you see is the origin of all art, you only need to look at rock-art with a guide like Lewis-Williams to see it.
The Chinese Written Character as a Medium for Poetry - Ernest Fennolosa
Edited by Ezra Pound, the most spectacular misunderstanding of language ever to be reprinted. It reads excellent and it gives us a language (Chinoiserie-Chinese) that does not exist in this world but should exist in a better world.
Vehicles - Valentino Braitenberg
I have read so much stuff relating to Cybernetics, AI, emergent systems and self-organization that I am totally saturated with it. The material itself is exciting but the professional obligation of science to be dull gets on my nerves. But this is an exception, wonderfully written and illustrated with funky little drawings. Vehicles is a tiny book but its size is deceptive. This introduction to synthetic psychology describes a number of simple responsive vehicles that with each new feature became aware of the world around them a good deal more. Each new vehicle is a new mind.
The Coleridge Notebooks.
Charles Lamb said he loved to lend his books to ‘Poet, Metaphysician, Bard’ Coleridge because he would return them with annotations more interesting then the book itself. Samuel Taylor Coleridge had a mind that was free, discursive, unruly and truly original. His notebooks record the flow of his thoughts as if you are sitting next to him. Every now and then I dip into this and always come out with some gem I never saw before. Get the Seamus Perry edition of this. Get a copy of the Road to Xanadu by Livingstone-Lowes for extra enjoyment.
Either the theory is crazy or it's one of the most groundbreaking discoveries in newer history.
Though no one takes Julian Jaynes seriously these days, but I think his ideas of the development of language preceding consciousness are as good as any other theories I've read.
"A book that is as strange as its title suggests. It is one of those books that is either complete rubbish or a work of consummate genius, nothing in between! Probably the former, but I'm hedging my bets."
By the way, the Wikipedia page about Jaynes' book uses part of that quotation, but cuts off the last sentence.
Dawkins provides a good summary of the book:
"Jaynes notes that many people perceive their own thought
processes as a kind of dialogue between the 'self and another internal protagonist inside the head. Nowadays we understand that both 'voices' are our own - or if we don't we are treated as mentally ill...
"Jaynes's suggestion is that some time before 1000 BC people in
general were unaware that the second voice - the Gilbert
Pinfold voice - came from within themselves. They thought
the Pinfold voice was a god: Apollo, say, or Astarte or Yahweh or,
more probably, a minor household god, offering them advice or
orders. Jaynes even located the voices of the gods in the opposite
hemisphere of the brain from the one that controls audible
speech. The 'breakdown of the bicameral' mind was, for Jaynes, a
historical transition. It was the moment in history when it dawned
on people that the external voices that they seemed to be hearing
were really internal. Jaynes even goes so far as to define this
historical transition as the dawning of human consciousness.
There is an ancient Egyptian inscription about the creator god
Ptah, which describes the various other gods as variations of Ptah's
'voice' or 'tongue'. Modern translations reject the literal 'voice' and
interpret the other gods as 'objectified conceptions of [Ptah's]
mind'. Jaynes dismisses such educated readings, preferring to take
the literal meaning seriously. The gods were hallucinated voices,
speaking inside people's heads. Jaynes further suggests that such
gods evolved from memories of dead kings, who still, in a manner
of speaking, retained control over their subjects via imagined voices
in their heads.

I am disappointed at the dismissive comments; perhaps those skimming he article failed to note Taylor's comment that 'religion is a story the left brain tells the right brain', and that she is capable enough to teach neuroanatomy at Indiana University's medical school - if she is not up to or interested in performing as much academic research, she has hardly become an anti-scientist.
It's quite possible to be a good materialist and still enjoy a spiritual dimension to life without evoking immaterial agencies or phenomena to do so; the different cerebration that seems to take place in the subordinate (usually right) hemisphere doesn't indicate less 'processing power' or 'buggy software'; it just processes incoming information differently, and the idea that there is nothing worthwhile to be learned this way is arguably foolish.
Indeed, there's a faulty syllogism at work here:
Scatterbrained mystics make unscientific claims about the right brain.
Taylor makes positive reports of improved mental state, following a temporary, documented inhibition of her left hemisphere.
Therefore, Taylor is a scatterbrained mystic whose claims are unscientific.
I don't see Taylor making any claims about immaterial causes or phenomena, either in this article or on her website, any more than the literature of Zen does, or any of the serious research into psychotropic drugs.
