# Mental content: fixed by the mind alone or shaped by the external world

This is a technical analytic-philosophy-of-mind survey on whether mental content is individuated by an individual's intrinsic properties (narrow content) or by facts about the environment (broad content, via Putnam's Twin Earth and Burge's semantic deference) — a debate about reference, truth-conditions and metaphysical individuation across possible worlds, with no emitter, receiver, diffraction, codex or creative event in it for the ideamorphism framework to grip; the surface echo between 'intrinsic vs. environment-dependent' and 'given vs. instituted invariant' is exactly the matter/form, physical/mental mapping that P3a's own constraint already rules out, so there is no non-trivial point of contact left to test.

## 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.*
