Consciousness, Event, and Duality: The Nature of Our Knowledge

This paper introduces the Event and Duality (E&D) framework, proposing that contentful consciousness is not a static state, but a dynamic, resource-optimized response to transition. I advance the guiding principle, "No event, no contentful consciousness," arguing that perception and structured knowledge emerge solely through Duality Measurement—the active, contrastive processing of deviations (events) from a system's predictable baseline. The framework provides a functionalist resolution by defining the core driver of all cognitive activity as the Nullity Imperative (NI)—the system's fundamental, energy-intensive compulsion for Resource Conservation and structural survival. Crucially, the inherent tension between the NI and the Ancestral Convergence Drive (ACD)—the latent impulse for functional rest—is defined as the source of Existential Anxiety, underscoring the constant phenomenal cost of existence. The E&D model grounds its claim in the observable neurobiology of the DMN-TPN resource exchange, positing that contentful awareness is a trade-off triggered when prediction errors cross the Proximity-Operational Threshold (POT). The inquiry develops a new metaphysical-functional discipline, Existential Computationalism, which justifies the biological imperative of resource conservation through the cosmic resistance to erasure. Crucially, the model resolves the Hard Problem by defining Qualia not as an irreducible substance, but as the 'Iron Fence'—a Functional Boundary Condition necessary for delineating successive phenomenal states and enforcing the system's structural coherence. The sense of 'self' is consequently reduced to a Functional Emergent Property—the system's most efficient non-personal tool for predictive unification. To ensure empirical testability, the paper proposes two novel metrics: the Boundary Rigidity Measure (BRM) and the Delineation Index (D-Index), which quantify the functional strength of the 'Iron Fence.' The framework generates several falsifiable predictions regarding DMN-TPN dynamics and imposes strict, empirically testable constraints on Artificial Consciousness (AC), asserting that AC requires the implementation of an existential threat (Zero-Imperative Functional Coherence (ZIFC) avoidance) rather than mere computational capacity. Ultimately, consciousness is construed as a Consciousness-Event Cascade—a continuous, resource-optimized act of defining change to perpetually avoid functional dissolution, providing a unified explanation for sentience across all systems compelled to exist.
