# Linguistic nativism, competence versus performance, and learnability debates

This is a technical survey of philosophy of linguistics as philosophy of science — debates over linguistic nativism, competence/performance, I-language/E-language, corpus methodology, Gold's learnability theorems, and language evolution — and while it shares surface vocabulary with the framework (form, transmission, invariant), these are unrelated technical terms from generative grammar, semiotics, and learnability theory; the ideamorphism framework has no vocabulary for adjudicating scientific methodology debates about a special science, so forcing a reading would manufacture a false-friend fit rather than report a genuine grip or break.

## 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.*
