A Solution to the Hard Problem of Qualia via Self-Referential Enrichment -Vis se tenet aevum Qualia as the Internally Accessible Difference Made by Self-Holding Dynamics

Abstract

We present a formal theory of qualia in which subjective experience is identified with the internally accessible difference generated by self-referential enrichment in an open metastable system. The framework synthesizes eight prior lines of work into a single architecture: Xi-Theory contributes distinction acts and integrity; Innernet contributes ontological levels and return dynamics; Absolibrium contributes spectral selection; Ubit/HPP contributes perspectival shadows; Droplet Mind contributes metastability, boundary tension, and coherence radius; Torus of Thought contributes the dual recurrent geometry of narrative and depth; CROWN contributes inverse reconstruction and uncertainty quantification; Full Picture contributes the principle that no structured pattern attains absolute closure. The central thesis is that qualia are neither static intrinsic properties nor inexplicable supplements to computation. They are the self-referentially accessible component of a system's own state-transition field. When a structured system closes a distinction upon itself through a self-model, the closure modifies internal organization: integrity, correlation length, phase relations, salience, and boundary conditions. The qualitative aspect of experience is the mode of this modification; its intensity is the magnitude of the accessible self-difference. We define the relevant state space, a phenomenality gate, a latent enrichment operator, and a reduced toroidal dynamics. We derive threshold conditions for phenomenal efficacy, characterize four dynamical regimes of self-reference, and formulate concrete experimental predictions in terms of reconstructable observables. The resulting theory offers a naturalistic, geometric, and computationally testable account of why there is something it is like for an organized system to undergo certain kinds of self-sustaining change.
