Recently I delivered the manuscript of my new book, The Secret Teachers of the Western World, to my publisher Tarcher/Penguin. The Secret Teachers of the Western World is an attempt to look at and understand the western esoteric tradition through the lens of split-brain psychology - via Iain McGilchrist’s fascinating work The Master and His Emissary, about the rivalry between our two cerebral hemispheres - and the “structures of consciousness” of the German-Swiss philosopher Jean Gebser. I’ve written about both in earlier books, McGilchrist in The Caretakers of the Cosmos and Gebser in A Secret History of Consciousness. I also reviewed McGilchrist’s book - you can find the review here - and have an essay on Gebser in Revolutionaries of the Soul. The book will be out later this year, and closer to publication I will post some excerpts here and on my blogs at the Daily Grail and Reality Sandwich websites. It’s the longest book I’ve done - just short of 200k words - and as you might suspect, it demanded a considerable amount of effort. I hope its readers find it worth it.
