The Calculus of Modal Coincidence - The Grammar of A-Metaphysical Ontology

This article proposes modal coincidence as the founding grammar of an a-metaphysical ontology. The more familiar description non-metaphysical correctly names what the project refuses: ontology need not secure what obtains through a bearer, substrate, essence, first principle, or concealed order standing beneath or beyond its obtaining. The term a-metaphysical states the stronger claim. The ontology is not constituted by opposition to metaphysics and does not depend upon metaphysics as the condition of its validity. It determines what obtains through the manner in which it obtains as this. The project occupies three distinct coordinates. It is genealogically post-metaphysical: its historical emergence presupposes the metaphysical tradition and its phenomenological, hermeneutic, and anarchic critiques. It is structurally pre-metaphysical: it articulates the obtaining prior to the metaphysical decision to duplicate it through a bearer or ground. It is ontologically a-metaphysical: its categories neither require metaphysics nor depend upon the negation of metaphysics. Metaphysics is a condition of the theory's discovery, not a condition of its truth. The category who provides the first decisive demonstration. A who is not a substance, organism, psychological profile, narrative bundle, public identity, or further fact behind a life. A who is the whole regional obtaining in which a regionally articulable manner obtains as this concrete occurrence. The determination is earned aletically before it is stated formally: from the transparency of ordinary who-directed access, through a substitution trial showing that preservation of every transferable structure — function, memory, narrative, qualitative profile, recognition — does not restore the same who, to the full hermeneutic concession and the residue it cannot absorb. The article then gives the claim a typed formal-phenomenological schema whose grammar blocks the return of bearerhood, composition, haecceity, and unrestricted transfer between regions, and develops the corresponding access principle: properly fulfilled who-directed deixis is a founded categorial intuition of modal coincidence — reaching the occurrence under the category who without producing who-status, reducing it to its sensible or public routes, or exhaustively knowing the life. The proposal combines positive no-ground, anti-bearer formation, regional warrant, deictic singularity, public assessability, fallibility, non-exhaustiveness, recurrence without identity, negative controls with open verdicts, and a strict distinction between who, public who-form, and locus of attribution. It is positioned in relation to Husserlian categorial intuition, Heidegger's existential analytic, Chiurazzi's modal ontology, Schürmann's destitution of archic principles, Vattimo's hermeneutics of weakening, personal-identity theory, and social ontology. On the strict criterion defended here — according to which an ontology must positively articulate its primitive distinctions, formation relations, consequences, error conditions, and modes of access — the article claims to found an a-metaphysical ontology in the strict constructive sense. The claim is architectural: it states the criteria on which it can be assessed and defeated, and its force lies in what the demonstration exhibits — that positive ontological determination without ground is available — rather than in any chronological assertion.
