Beyond the Exclusion Axiom: Translational Ontology as a Foundation for Integrated Information Theory

Why these five axioms and not others? IIT's foundational structure rests on phenomenological stipulation rather than principled derivation—a gap that has resisted resolution within IIT's own resources. This paper closes that gap. We introduce Translational Ontology, a meta-ontological framework that derives four of IIT's five axioms from the structure of description itself, replaces the contested exclusion axiom with the Maximum Ψ Principle, and dissolves the substrate-selection problem by showing that descriptive regimes are self-constituting. The central concept is translation resistance: the structural non-isomorphism that persists between any two descriptive regimes after all available translation operations have been applied. Grounding translation resistance in the Fisher–Rao metric, we define Ψ (Translation-Closure Integration) as the geodesic excess of an experiential trajectory—a trajectory-level complement to Φ that allows multiple experiential streams to coexist with graded phenomenological salience. The result is an extension of IIT, not a rejection: consciousness is not what happens when integration overcomes resistance, but what happens when resistance is inhabited productively.
