From Quantum Unity to Erosive Continuity: A Metaphysical Reconstruction of Reality in the Horizon of Finite Continuity Ontology

This article presents a novel model for rethinking the foundations of metaphysics by synthesizing the quantum framework of Tathāgatagarbha with Morteza Niami's Finite Continuity Ontology. In this approach, quantum concepts are employed not as physical proofs of Buddhist metaphysics but as structural models for understanding relationality, non-separability, and emergence. Finite Continuity Ontology demonstrates that the underlying unity of reality is never experienced as a complete, frictionless whole but is always realized through processes of erosion, temporary collapse, reconstruction, and unstable stabilization. The central thesis—termed the Fundamental Erosion Principle—asserts that no entity exists initially in complete form and subsequently undergoes erosion; rather, every entity emerges from the outset as a temporary stabilization within an erosive field. Within this framework, Tathāgatagarbha is reconceptualized from a hidden essence of awakening to the reconstructive capacity of finite systems facing erosion, and Resistant Synchronization replaces total synchronization. Drawing on the principle of structural isomorphism, quantum concepts are employed not as descriptions of physical reality but as structural patterns for understanding the emergence of multiplicity from a unified substrate, thereby avoiding critiques of quantum reductionism. The critical comparison section demonstrates that this apparatus distances itself from Spinoza (due to substantialism), Heidegger (lack of criteria for measuring continuity), Deleuze (sanctification of change without attention to threshold of sufficiency), and Malabou (reduction of plasticity to the neural level). The article concludes that Erosive Continuity Metaphysics constitutes not merely a theoretical synthesis but a novel research program in which existence is not a given datum but a provisional achievement maintained through resistance, reconstruction, and leakage regulation.
