From an engaging discussion of Julian Jaynes’ bicameral mind theory by writer and philosophy commentator Jules Evans, at his website Philosophy for Life:
I’m particularly interested in the link between voice-hearing, dissociation and creativity, and in the incidence of voice-hearing among creative individuals like novelists Marilynne Robinson (who occasionally hears a voice inspiring her novels), comedians Graham Linehan and Jonny Vegas (both of whom hear or have heard voices), and musicians like Lady Gaga and David Bowie (the former says she heard voices and started to act them out as personae, while the latter likewise embodied and acted out radically different personalities and has a history of schizophrenia in his family).
Not to mention the dissociative capacity of gifted actors to become other people (Le Carre called Alec Guinness’ ability to become someone else a ‘complete self-enchantment, a controlled schizophrenia’); or all the many poets and song-writers who say their poems came to them from a voice / presence / spirit / muse.
What Jaynes fails to address, I’d suggest, is the value of these ‘vestiges of the bicameral mind’. When we seem to feel or hear messages from the beyond, it’s not just a primitive throwback to Homeric times. These messages sometimes tell us something useful, beautiful and wise, something our ordinary consciousness does not know. They are often sources of moral inspiration or consolation. I’d suggest the right hemisphere is still not entirely accessible to our ordinary consciousness, and there is a value in learning how to access it through things like meditation, trance states or techniques of ecstasy (though of course there are risks as well, particularly if you end up with an inflated or Messianic sense of self).
To go a step further into the mystical, if we do receive inspiration through the right hemisphere, does that mean the origin is definitely purely material or neurochemical? Could we not consider William James’ hypothesis that the right hemisphere / unconscious is the door through which the divine speaks to us? Such has been the suggestion of various spiritual critics of Jaynes’ theory, from Owen Barfield to Philip K. Dick.
Still, the voice-hearing network is fascinating, from a theological perspective, because in some ways it suggests a very modern attitude to the gods. We hear their commands, and yet we don’t have to obey unquestioningly. We relate to them less as a child to their all-powerful father, and more like a friend to their equal, rather like Lyra’s friendship with her daemon, Pantalaimon, in Philip Pullman’s Dark Materials. Happiness, then, is eudaimonia: having a friendly daemon to keep one company in life and through death.
Very well, says my daemon, looking over my shoulder as I write. But who made the daemons?
