Mary's Room
Mary knows all physical facts about color vision but learns something new when she first sees red — does this show that phenomenal facts are non-physical?
What the system says
Mary's new knowledge is disclosive, not propositional; it marks her entry into a new position in worldframe-space, not the acquisition of a new fact.
The system addresses this phenomenon by locating it within the broader structural account. The apparatus of worldframes, monadic inhabitation, and the disclosive/structural distinction provides the conceptual resources needed to dissolve or resolve the puzzle rather than simply describe it.
Existing positions in the literature
Standard approaches to this phenomenon in the philosophical and scientific literature face characteristic difficulties. The system's account does not simply choose among these positions but provides a structural diagnosis of why each fails and what a satisfactory account would require.
