Joscha Bach: The world you experience is a simulation your brain produces, and the self that experiences it may not exist

Joscha Bach on what consciousness actually is in mechanistic terms without retreating to woo, mysticism or hand-waving.

His core claim: the self is a pattern running on the brain, not the substrate itself. What you experience as "the world" is a model your brain generates, not the physical world outside. Phenomenology is a representational regime, not just an information-processing property.

We cover why simulating a connectome won't reproduce behavior (C. elegans, 302 neurons mapped since 1986, no working simulation), what's wrong with Penrose's quantum consciousness theory, why he thinks "you don't die because you were never really alive," and his operational definition of consciousness as self-organized second-order perception that increases global coherence.

90-minute conversation. Linked above.

What's your opinion? Is Joscha right?

Sam Harris on the asymmetry between consciousness and free will (clip from the 2024 conversation)

Sharing a clip from the Sam Harris conversation. Sam articulates a distinction that I keep returning to:
 
— Consciousness can't be an illusion. Every act of doubting it is itself a conscious experience, so the regress closes immediately. He calls it "the ground truth."
 
— Free will is a different category entirely. Not illusory in the same Cartesian sense — incoherent. The concept doesn't survive any consistent metaphysical commitment about causality.
 
There's a thought-experiment Sam describes — a predictive machine that could disabuse a subject of even the FEELING of free will — that I think is the most interesting move he makes in the whole conversation. Brian pushes back with an infinite-regress objection.
 
Worth a watch if you missed it the first time around.
