To underline some of Tony Wright's points, and provide connections to other speakers, his talk is juxtaposed with material from other episodes. We begin with episode 465, a reading of Charles Eisenstein's Ascent of Humanity about the Pirahã, one of a few tribes who still live a traditional life in the tropical forest, whose language and culture is singularly unaffected by modern man. Could they, perhaps, still have a healthy balance between brain hemispheres?
For clarification of the roles of the two hemispheres, we replay the conclusion of what Iain McGilchrist had to say about brain function:
"If I had to sum it up, I'd say the world of the left hemisphere, dependent upon denotative language and abstraction yields clarity and power to manipulate things that are known, fixed, static, isolated, decontextualised, explicit, disembodied, general in nature, but ultimately lifeless. The right hemisphere by contrast yields a world of individual changing, evolving, interconnected, implicit, incarnate, living beings, within the context of the lived world, but in the nature of things never fully graspable, never perfectly known, as we think, and to this world it exists in a certain relationship, rather than just an objective stance." — Iain McGilchrist, UG#537
To finish we hear the conclusion of UG#525, Michael Pollan's ideas on changing consciousness, which seem to correlate pretty closely with Tony Wright's ideas of the co-evolution of plants and humans.
Thanks to Keith Scott Mumsby for the Tony Wright interview
The left/right brain issue is addressed with powerful tesimony in the first talk of UG#655.
