The Necessary Structure of Awareness

Consciousness has been defined inconsistently across philosophy, cognitive science, neuroscience, and artificial intelligence. This work does not attempt to explain subjective experience or phenomenal content. Instead, it proposes a minimal structural criterion distinguishing intelligent systems from systems for which the concept of awareness becomes structurally unavoidable. Awareness is defined here as a self-referential update process in which a system irreversibly modifies its own governing structure over time while maintaining system identity. This criterion is not intended as a sufficient theory of consciousness, but as a boundary condition clarifying when purely functional descriptions cease to be adequate.
