Consciousness-Noumenon Isomorphism: Formalization Boundaries, the Hard Problem of Consciousness, and the Ontology of Human Cognition

This paper develops an axiomatic framework to characterize the strict logical boundary between formalizable systems and non-formalizable conscious phenomena, grounded in computability theory, intuitionistic set theory, Kantian ontology, and contemporary consciousness science. We propose the consciousness-noumenon isomorphism thesis: human consciousness is a special manifestation of the Kantian noumenon that preserves its original non-formalized structure, making it the only entity capable of directly accessing the noumenon and generating formalized systems. We prove that all formalized systems are products of consciousness’s self-reflection and abstraction, and that formalization is inherently a process of objectification and detachment from the noumenon. Any attempt to formalize consciousness itself destroys its essential isomorphism with the noumenon, eliminating its ability to perceive reality and create new formalized structures. We further formalize the bidirectional interaction mechanism between the two domains, showing that their dynamic coupling resolves the hard problem of consciousness and provides a unified account of human cognitive history as an infinite process of interaction between non-formalized consciousness and evolving formalized systems. We derive falsifiable predictions about the limits of artificial intelligence and the nature of human uniqueness.
