Nanopublication — A sentence that calls itself false, and how logic tries to survive it

Declined — no-purchase ^[1]

Propositional grid ^[2]

Read this grid. “Not evaluated” does not mean the source has nothing to say about that proposition. It means the reading did not instruct it. That is not a result, and it counts in no denominator. A silence, by contrast, is a finding: the reading touched the proposition without concluding, or noted its absence itself.

Not evaluated (37) — P1, P2, P3, P3a, P4, P5, P6, P7, P8, P9, P10, P11, P12, P13, P14, P14a, P14b, P15, P16, P16a, P17, P18, P18a, P19, P19a, P20, P21, P22, P23, P24, P25, P26, P27, P28, P29, P30, P31

Overall verdict: DECLINED:no-purchase — taxonomy of the August 2026 pass, predating the move to relational verdicts. Kept as metadata: the gap between the two forms is data, not residue. This reading’s judgement is in the grid above.

First pass — kept as written

Reading produced by the T50 RSS pass, before the boundary lens. It is reproduced UNCORRECTED. Keeping it is the point: without it, a changed title is just a changed title — with it, what the second pass refused becomes legible.

Title it carried : « The Liar Paradox as Self-Diffracting System: Logic's Ouverture Problem »

The liar paradox is a structural case of diffraction within a closed system. The statement 'this sentence is false' emits a signal (its propositional content) through the logical ouverture of classical truth-value assignment. But the ouverture cannot receive it without transforming it — the signal diffracts into contradiction. This is not a bug in logic; it reveals that meaning cannot be lossless within self-referential systems. The paradox demonstrates that 1 ≠ 1 at the level of formal semantics: the same utterance cannot maintain invariant truth-value when it becomes its own receiver. Modern resolutions (paraconsistency, hierarchy, revision theory) are attempts to engineer the diffraction deliberately — to design an ouverture that can absorb self-reference without collapse. The codex of classical logic was not built to handle its own emission.
