A Formal Ontology of Self-Referential Structure: Reconstructing and Defending the Subject-Object Identity Thesis

The subject-object identity thesis has long been regarded as a mystical intuition. Employing formal logical tools, this paper constructs a formal ontological model of this thesis by building a mereological partial order structure and establishing a self-reference monotonicity premise, demonstrating that it constitutes a formal model of a set of logically consistent metaphysical axioms. Through a top-down holistic instantiation approach, this model circumvents the combination problem of panpsychism and provides a metaphysical reference point for the science of consciousness. This paper strictly respects the disciplinary boundary between philosophy and science. It is a work in metaphysical ontology and does not provide empirically testable predictions; it offers only conceptual clarification.
