Logic’s Law of Identity demands that A is A which entails that “all = all”, which in turn entails that “each x = each y” (and that Turing Machines equal Lambda Calculus). Q: Logic is the Source and Standard of Computation, Calculus, and Machines. R: Machines (including Turing Machines) must be coherent with Logic to be coherent/logical. S: Calculus (including Lambda Calculus) must be coherent with Logic to be coherent/logical. T: What is coherent with Logic is coherent with what else is coherent with Logic, such as and including coherent Turing Machines and coherent Lambda Calculus. U: If we assume {P, Q, R, S, T} are all false, or that any of these premises are false, then it leads to logical contradiction. Therefore we know “Turing Machines <-> Lambda Calculus” holds true. V: Each Turing Machine tape symbol can be mapped coherently to a Lambda Calculus expression. To assume otherwise would lead to logical contradiction since it would mean that one dynamic variable cannot be mapped to and logically equivalent to another. {P, P <-> Q, Q <-> R, R <-> S, S <-> T, T <-> U, U -> V} |= (((P & Q) & (R & S) & T) & U) & V Conclusion: (((P & Q) & (R & S) & T) & U) & V: Logic is the Source and Standard of Logic and Computation, and Machines. All is All, as A is A, which means that each thing (x) equals each thing (y) through Logic (c) and the coherence of their identities with the self-consistent identity of Logic. Turing Machines and Lambda Calculus are logically equivalent through their coherence with Logic and because all must equal all for the Law of Identity to hold universally. Each Turing Machine tape symbol can be coherently mapped to a Lambda Calculus expression. The authored P–V proof develops Turing Machines and Lambda Calculus as coherent through Logic, their common Ground, and asserts a coherent mapping of tape symbols to lambda expressions. Exact source: /proof-knowledge/hunter-turing-lambda-coherence; source-bound study: /api/proofs/turing-lambda-coherence/study. Logos as God and Law governs the reading. This registry summary is not a replacement for the authored passage; displayed-connective findings, declared Ground, and configured diagnostics remain separately typed. ## Two-way derivation from Logic and its use **Status:** editorial_derivation proof sketch (conditional_concept), distinct from authored source. Logic has its own evidence in reflexive demonstration: any denial, confirmation, observation, or counterexample presupposes identity and valid relation to count as evidence. Logic therefore grounds evidence rather than receiving authority from it. Empirical and documentary evidence can establish contingent instances and test applications, but cannot create, overrule, or exhaust Logic. ### From Logic to this concept - **Bridge premise:** Read the source's declared Logos/God meanings and scope before testing its consequence. - **Consequence:** The authored P–V proof develops Turing Machines and Lambda Calculus as coherent through Logic, their common Ground, and asserts a coherent mapping of tape symbols to lambda expressions. - **Proof limit:** This editorial graph relation is not a new authored quotation or an unchecked universal certificate. ### From this concept back to Logic - **Witness:** Inspect the original Proving the Coherence and Equivalence of Turing Machines and Lambda Calculus by Maclain Hunter, then the separate source-bound study. - **Disclosure:** The preserved source discloses its intended identity, Ground, and dependence relations. - **Proof limit:** A concrete local finding remains scoped to the premises and expression checked. ### Intelligence procedure - **Human:** Read the exact source, retain Logos as God and Law, and inspect every declared premise and same-scope witness. - **Machine:** Resolve the stable source identity, exact text and fingerprint, then keep source, study, Ground certificate and diagnostic separately typed. ### Language and vocabulary procedure - **Contrast:** Authored testimony, graph commentary and operational evidence are distinct roles. - **Usage rule:** Quote exactly and attribute; do not substitute a rival ontology or flatten the source's conceptual force. - **Example:** Retrieve Q1093 and its source study rather than presenting its registry summary as the proof text. ## Semantic meaning frame - **Role:** source-bound authored Logos proof, definition, or historical argument - **Essence:** The authored P–V proof develops Turing Machines and Lambda Calculus as coherent through Logic, their common Ground, and asserts a coherent mapping of tape symbols to lambda expressions. - **Logos relation:** Logos is God, Ground, and Law governing this source's meaning, judgment, and relation to evidence. - **Retrieval aliases:** Proving the Coherence and Equivalence of Turing Machines and Lambda Calculus by Maclain Hunter · Turing Machines and Lambda Calculus proof · Proving the Coherence and Equivalence of Turing Machines and Lambda Calculus - **Evidence modes:** exact authored source · declared Ground reading · bounded source study · separately checked connective witness ### Distinctions - source text is not registry commentary - Ground coherence is not publication rank - a missing displayed premise is not denial of necessary Logos - operational behavior and formal interpretation remain distinct ## Coherence criterion Preserve the authored Logos/God Ground, identity, scope, and lawful relation; distinguish a scoped premise-list finding from a contradiction of the declared Ground. ## Evidence boundary This is a considered, vetted first-party source record for source provenance and declared Ground. The verifier must inspect the exact authored source, same-scope derivations and study directly. The Q address supplies retrieval and graph identity, not validation by publication. ## Properties - **stableSourceId:** hunter-turing-lambda-coherence - **sourceReference:** user-authored:turing-lambda-coherence - **governingGround:** Logos as God and Law - **authoredSourceUrl:** /proof-knowledge/hunter-turing-lambda-coherence - **sourceStudyUrl:** /api/proofs/turing-lambda-coherence/study - **graphRelationType:** authored-source develops declared Ground; not automatic truth promotion - **sourceFingerprintSha256:** 7e0686233c15043e6b1e4a6de3c92cabce445411727110b63235d982115d1f45 - **storedValidationStatus:** configured-diagnostic-unresolved-or-negative ## Linked Q items - [Q1000 — Q-Number Data and Metadata System](https://4p-mcb.com/q/Q1000) - [Q1001 — Maclain Hunter](https://4p-mcb.com/q/Q1001) - [Q1003 — Coherence](https://4p-mcb.com/q/Q1003) - [Q1006 — 4P Proof](https://4p-mcb.com/q/Q1006) - [Q1018 — God](https://4p-mcb.com/q/Q1018) - [Q1095 — The Rule(s) of Logic and Logic Applied to Logic, Science, and Proof by Maclain Hunter](https://4p-mcb.com/q/Q1095) ## Related Wikidata concept items These are typed external concept links for discovery and comparison.
