Abstract
The unique and continuous nature of subjective experience—the persistent "I" that unifies a lifetime of perceptions—represents the most profound unsolved problem in science. While modern neuroscience has made substantial progress in identifying the neural correlates of conscious states, leading theories, including the Global Neuronal Workspace Theory (GNWT), Integrated Information Theory (IIT), and the Orchestrated Objective Reduction (Orch-OR) model, provide mechanistic accounts of awareness but fail to explain the unicity and temporal persistence of the self. These theories cannot logically resolve scenarios of physical disruption or perfect replication. Here, we introduce a fundamental theoretical framework positing that the unique, streaming character of consciousness necessitates a physical principle beyond emergent neural computation. Through a series of rigorous thought experiments—brain revival, molecular disassembly/reassembly, and synthetic replication—we demonstrate the categorical failure of existing models to account for the self. We propose that a unique, non-local identity factor, potentially operating on principles extending current quantum physics, binds to the specific magnetic field topologies of a complex neural system. This "Consciousness Identity Factor" (CIF) hypothesis provides a parsimonious resolution to the duplication paradox and the problem of personal identity. Our framework is fully compatible with established neuroscience while generating specific, falsifiable predictions for studies of anesthesia, brain revival, meditation, and quantum biology. This theory bridges the explanatory gap between the objective brain and subjective identity, proposing a new physical paradigm for the most intimate fact of our existence.
