Local Evaluative Collapse: Looking Past the Tarskian Hierarchy

Abstract

This research note presents a surgical resolution to the Liar Paradox by identifying Local Evaluative Collapse (LEC) as the structural consequence of an illicitly established identity relation. Building on Arthur Prior’s (1971) observation that statements implicitly purport their own truth, I argue that "This statement is false" functions as a covert contradiction—semantically equivalent to "It is true that this statement is false." Unlike formal systems which utilize Gödel numbering as "substitution fuel" to make the enumerator and the enumerated interchangeable, ordinary language lacks valid grounds to leap the categorical divide between referrer and referent. When the singular valid interpretation required for paradox—"The true statement entirely and only about itself is false in nothing but itself"—is made explicit, it is instantly rejected as contradictory nonsense. This note generalizes the phenomenon to formal systems, arguing that Local Evaluative Collapse is triggered when structural admissibility is revoked—“nonsensed”—by distinct disproof reductio. Finally, it posits that admissibility remains a latent burden on the truth function (analogous to the unmeasured wave function) so long as contradictions remain covert, collapsing to observed incoherence only upon disproof realization.
