Timeline of Consciousness: A Cognitive-Historical Trajectory Toward Reflexive Intelligence

This paper reconstructs the evolution of human cognition as a trajectory of frame transitions—shifts in the dominant epistemic architectures that define how reality is perceived, narrated, and navigated. From mythic participation and theological authority to rational abstraction and metacognitive self-reflection, the timeline reveals consciousness not as a fixed faculty, but as a recursive, frame-sensitive process. Each epoch is analyzed through its mode of sense-making: narrative embedding, textual revelation, axiomatic modeling, and finally, frame-awareness. The emergence of Pure Reason—defined here not as Kantian idealism, but as reflexive cognition—is positioned as the threshold where thought becomes self-modifying. This timeline is both historical and structural: a map of how reflexivity emerges through the breakdown and recomposition of cognitive systems. It offers a framework for understanding the epistemic architecture required for both human and artificial systems capable of conscious self-revision.
