E181 - Joscha Bach: A Cognitive Scientist’s Guide to Consciousness & The Illusion of Reality

Joscha Bach explores the nature of consciousness, free will, and reality through the lens of computation, cognitive science, and philosophy. Rather than treating the mind as a mystical entity, Joscha frames consciousness as a constructed dream—a model generated by the brain to make sense of the world and coordinate behavior.

We examine why beliefs should remain provisional, how the self functions as a useful fiction, and why suffering emerges when internal learning signals misfire. Joscha explains why free will feels real even if decisions arise before awareness, how meaning exists beyond the individual ego, and why wisdom is not simply knowledge but the ability to orient oneself within larger systems of value.
