Psychedelics, Quantum Mechanics and Hyper Reality | Christof Koch & Bernardo Kastrup

Quick Overview

Neuroscientist Christof Koch, having experienced a mystical, non-dual experience, shifted his ontology, leading him and philosopher Bernardo Kastrup to discuss rigorously taking such mystical experiences seriously by exploring commonalities between consciousness studies (like IIT) and the foundations of quantum mechanics, particularly the role of information and whether quantum effects are necessary for brain function.

Key Points: Christof Koch described his mystical experience as profoundly experiencing a universal consciousness that was "hyperreal, more real than than than everyday reality," shifting his metaphysical beliefs at age 67. Bernardo Kastrup notes that both leading theories for physical entities (foundations of physics) and mind (Integrated Information Theory, IIT) heavily leverage information theory, suggesting a potential bridge between the domains. Koch became more open to quantum mechanics' relevance in the brain, contrasting his former view that the brain is too 'wet and warm' for quantum effects, stating, "anything that's not ruled out by by and by physics, we should test." The speakers differentiate meaningful rigorous exploration from becoming 'flaky' after a mystical experience, emphasizing the need to maintain scientific rigor, conceptual clarity, and empirical evidence, contrasting this with people who 'lose their marbles.' Koch and Hart Naven hypothesize that consciousness arises from the formation of a quantum superposition (like Schrödinger's cat being both dead and alive), rather than its collapse, which is compatible with the Many-Worlds Interpretation (MWI). They discuss testing quantum effects via xenon isotopes (Xe-129/131 vs Xe-128/130) in anesthetics, where differences in nuclear spin (a quantum property) might affect anesthetic potency, which, if proven, would 'trigger a mass revolution' in quantum biology. Kastrup argues against MWI because conscious experience must be definite ('every experience is definite'), preferring to model what is empirically accessible rather than positing unobservable parallel universes, despite acknowledging the operational utility of MWI for quantum computing.
