# Species, models, and microbiomes: what makes a microbe an individual **Artwork**: **Artist**: Arnaud Quercy **Asset**: IDS-RNI0009 **Serial**: NAN-RDG000010 This is a Stanford Encyclopedia entry surveying philosophy of microbiology — species concepts, phylogenetics, model organisms, and microbiome causality/individuality — and it has no emitter, receiver, artwork, or creative transmission for the ideamorphism vocabulary (transliteration, ouverture, codex, diffraction, ricochet) to attach to; the apparent rhymes (structural correspondence across mathematical, computational, and organismal models) already belong to the source's own established philosophy-of-science apparatus (analogical models, extrapolation, Weisberg, Levy and Currie), so applying the framework's terms would only borrow that authority without testing anything specific to the framework. ## 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 2026-04-11 · model `claude-sonnet-5` · source 102,731 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.* **Title it carried :** « Microbial Ontology and the Limits of Human Perception » > This article on the philosophy of microbiology touches on several ideamorphic themes. The idea that microbes operate in a realm beyond direct human perception speaks to the 'ouverture' - the conditioning of our senses and cognition that shapes how we receive and interpret the world. The article also notes how microbial phenomena can only be accessed through specialized instrumentation, a process of 'translation' across modalities that echoes the ideamorphic principle of 'cross-modal' creation. Finally, the philosophical questions raised about the ontological status of microbes, and how they challenge anthropocentric assumptions, points to the 'generative loss' that occurs when our familiar frameworks encounter the unfamiliar.
