UGI and the McTaggart Paradox: Ontological Permanence and Symbolic Inversion

McTaggart’s paradox arises from conflating two structurally distinct temporalities: symbolic time, the A-series of past, present, and future produced by the mind’s inversion cycle, and ontological time, the B-series of stable coherence relations described by physics. The Universal Grammar of Inversion (UGI) shows that symbolic flow results from the Rise–Permanence–Meta cycle that generates meaning, whereas ontological time expresses a fixed relational order that contains change without becoming. This separation dissolves the paradox by revealing that A-series dynamism is a symbolic operation rather than a property of events. The paper introduces a further distinction between two ontological models: the classical block universe and a generative universe in which new states are produced sequentially. In the block universe, symbolic flow is often mistakenly projected onto a static ontological structure, producing the illusion of temporal passage. In the generative universe, ontological change arises from state-generation without implying flow, allowing the symbolic and ontological layers to remain sharply distinguished. The paradox therefore disappears for opposite reasons: it is masked by conflation in the block universe and dissolved by separation in the generative universe. UGI thus provides a unified account of temporal experience and physical structure, showing how symbolic inversion generates the phenomenology of time while ontological coherence structures, whether blocklike or generative, remain tenseless. This dual-layer model clarifies why physics lacks temporal becoming, why experience cannot do without it, and why the McTaggart problem persists only when these layers are confused.
