The Structural Evolution of Subjective Awareness

This framework proposes a two-stage evolutionary account of phenomenal Consciousness. The first stage involves the binding of exteroceptive perception, interoceptive motivational state, and affective valence into a unified semantic field. Core valence qualia — pleasure and pain — are not incidental features of this system but its structural binding agents: they couple sensory input to motivational Relevance and encode the organism's trajectory relative to its needs, enabling generalizable associative learning. The product is a core Consciousness: a valenced, unified field that is the minimal substrate of subjective experience.

The second stage is corticalization. The cortex does not generate Consciousness from scratch but models mindedness from within an already-valenced affective field. Posterior cortical regions integrate multimodal sensory streams into a coherent perceptual field — the sentient interior. Anterior regions, via working memory architecture, access that field through a central executive, manipulating content through visuospatial and phonological subsystems. Conscious attention is characterized here as adverbial: it does not add new content but qualifies existing content with the properties of hereness, nowness, and togetherness.

The overall system functions as a globally broadcast virtual field — a model of the organism's own minded activity that enables prospective and retrospective cognition. This maps onto the transition from Mind 1a (core affective binding) to Mind 2 (full reflective Consciousness) in the Map of Mind framework. The plasma ball serves as a structural analogy: a central energized core whose filaments reach outward in response to contact, illuminating the whole from within.
