Jonathan Dickerson: Ibogaine and the Bicameral Mind

Earth AncientsSep 2, 2026

Author and Ambio Life Sciences co-founder Jonathan Dickinson explains ibogaine, a powerful psychedelic from the root bark of a Central African shrub, and why it is drawing attention as a treatment for opioid addiction, PTSD and traumatic brain injury in Navy SEALs. He borrows Julian Jaynes's theory of the 'bicameral mind' to describe how users often enter a dreamlike dialogue with inner voices or guides, sometimes reporting knowledge of distant cultures, ancestors or the future. Host Cliff Dunning opens the episode with claims that around 40% of current Maya hieroglyph translations may be wrong, and that very old kings are routinely dismissed as myth.
