# What counts as death: brain criteria, circulation, or a contested cluster of concepts **Artwork**: **Artist**: Arnaud Quercy **Asset**: IDS-RNI0168 **Serial**: NAN-RDG000112 This is a Stanford Encyclopedia of Philosophy survey of competing definitions and criteria for human death (whole-brain, brainstem, higher-brain, circulatory-respiratory, cluster-concept views), and the ideamorphism framework's vocabulary of emission, reception, codex, diffraction, and invariant addresses artistic creation and transmission of ideas across modalities — the two share no substantive claim to test against each other, only incidental lexical overlaps (e.g. 'irreversibility', 'process/event') that do not connect to any of the framework's actual propositions. ## Context ### Declined — `no-purchase` [@source] ### Propositional grid [@p31] > **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.* Reading of 2026-07-11 · model `claude-sonnet-5` · source 113,861 chars · 1 attempt(s) --- ### 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.* > This entry sits at the intersection of philosophy and public policy — a case where the codex (the formal system of how we define death) has material, irreversible consequences. The revision reflects generative loss: the gap between philosophical precision and policy implementation is not a failure to be eliminated but the productive space where meaning must be negotiated. Each revision of the definition generates new diffractions through medical, legal, and ethical ouvertures — different receivers (clinicians, legislators, families) will diffract the same intentional invariant (what constitutes human death) into incompatible but equally valid interpretations. The entry documents not a convergence toward truth but the engineering of controlled incompleteness. T50 RSS assessment · 2026-07-11 · remplacée par `boundary-lens-2026-08`
