I have published two papers on State Structural Theory. The first is the foundational paper, which introduces the core idea of describing the world as non-identical states rather than enduring entities. The second is the complete paper, which presents State Structural Theory as a self-contained world model, including formalization, cognition, meaning, emotion, and applied mappings. Both papers are intended as structural descriptions rather than explanatory or empirical theories.They can be read independently, but together they present the full scope of the theory.
Yugo Matsumoto (Sun,) studied this question.
