Physics as the User Interface of Consciousness: A Kantian-Bayesian Synthesis of Zen Impermanence and Quantum Mechanics

Abstract

[Author’s Note]This paper is retained as a historical record. The informal ‘Kantian-Bayesian’ framework presented here has been entirely superseded by the Light & Flux (L&F) framework, which corrects the temporal substrate circularity, introduces a three-tier formal ontology, and provides a rigorous deductive derivation of complex Hilbert space from inferential constraints. See [DOI of L&F V5]. For a broader, accessible exploration of this framework and its implications for the nature of reality and mind, follow the Substack publication: Mind & Machine. Original AbstractModern interpretations of Quantum Mechanics, particularly Quantum Bayesianism (QBism) and the Free Energy Principle, increasingly suggest that physical reality is not an observer-independent ontology but a generative model constructed to minimize predictive error. This paper proposes a formal synthesis between this "Physics-as-Interface" paradigm and the phenomenology of Eastern Zen philosophy. We argue that the Zen concept of "Subtle Impermanence" (Anicca) is mathematically equivalent to a Latent Markovian Substrate, while the "illusion of constancy" maps rigorously to the Belief State (q(x)) maintained by the observer to facilitate inference under partial observability. By framing the Wave Function not as a physical object but as a computational strategy to mitigate Variational Free Energy, we demonstrate that the laws of physics are essentially stability protocols encoded by consciousness. This synthesis moves beyond metaphorical comparisons, offering a rigorous, information-theoretic grounding for the convergence of Eastern phenomenology and Western computational mechanics. Key Theoretical Contributions: The Markovian Noumena (Hardware): Reinterpreting Kant’s Noumena as a Latent Markov Process (x_t)—a generative substrate of discrete, conditionally independent moments that lacks intrinsic object permanence. The Non-Markovian Interface (Software): Defining conscious perception as a Belief State ($q(x)$) that acts as an "Active Buffer." This interface imposes a non-Markovian constraint (memory/history) onto the latent data to construct a navigable user interface. Wave Function as Belief State: Aligning with QBism, we formally equate the quantum wave function (Ψ) with the observer's internal belief state, where "collapse" is redefined as a standard Bayesian belief update minimizing prediction error. Free Energy & Complexity: Utilizing Friston’s Free Energy Principle, we argue that "Causality," "Time," and "Objects" are optimal compression algorithms derived to minimize the Complexity Cost (KL Divergence) of the internal model. The Thermodynamics of Time: Proposing that the "Arrow of Time" is an artifact of Inference Asymmetry, where predicting a divergent future requires higher computational entropy than retrodicting a convergent past.
