Selects: Thrill to the Stunning Bicameral Mind Hypothesis
Summary
Josh and Chuck explore Julian Jaynes’ controversial bicameral mind theory, which posits that humans only developed modern consciousness around 3,000 years ago. They discuss how ancient people may have experienced auditory hallucinations as divine commands rather than internal thought, a state that ended with the rise of metaphorical language and writing. The hosts examine evidence from ancient literature like the Iliad, split-brain studies, and child development to evaluate whether consciousness is a learned skill rather than an innate trait.
