Abstract

This paper reformulates the hard problem of consciousness within the framework of Difference Monism (DM). Rather than asking how physical processes bridge to subjective experience, it asks: what kind of structure develops internality sufficient to host consciousness? The paper identifies four threshold conditions (stable boundary, internal differentiability, folded-back inheritance, subject-level integration), distinguishes DM from IIT/GNW/illusionism, and establishes a falsifiable negative boundary claim: complete third-person translation cannot residuelessly substitute first-person access.
