Definition
Metabolism names the materially sustained activity through which living organization obtains energy and produces components needed for its continuation. It supports persistence through ongoing exchange rather than unchanging matter. AB and RB3 also extend the term to the energy, material and labor infrastructures sustaining technical systems; that extension does not establish that an AI model is a self-producing organism.
Explanation
AB describes form persisting while matter passes through it, but distinguishes regulated living traffic from a flame's burning. Metabolic resilience sustains a living configuration, while reproduction transmits forms. PB places metabolism among the relations constituting a body rather than defining a sealed object. RB1 describes enzymes working in concert and leaves metabolism's universality beyond Earth's life unsettled.
RB2 differentiates metabolism and repair through Rosen: energy and component production interdepend with maintenance and replacement. Bacterial regulation can adjust metabolism to preserve viability; metabolic work sustains form through energetic openness. Closure alone does not entail anticipation. RB3 places metabolism within continuing individuation and emphasizes dissipative costs. Its infrastructural metabolism, like AB's hidden body of AI, identifies distributed supports and expenditure. AB expressly locates current systems' repair in engineers and closure through the company, not the model. RB3 extends the cost question to institutions and platforms.
Scope and attribution
All five books support biological treatments, but PB supplies only a relational application. The infrastructural extension belongs to AB and RB3. RB3's metaphor of metabolizing past constraints into repair is not physiological evidence.
AB — The Actual Book
Metabolism sustains form through regulated material work. AI's hidden metabolism concerns infrastructure, not model-level self-production.
Occurrence locators: 13, 43, 44, 58, 76, 100, 123, 128, 133, 145, 155, 159.
PB — The Possible Book
Metabolism is a bodily relation alongside air, food, perception, memory and care; the body is not sealed inside skin.
Occurrence locators: 33.
RB1 — The Real Book, Volume I: The Possible Is Real
Metabolism is enzymes working in concert; its universality beyond Earth's life remains unsettled.
Occurrence locators: 21, 30, 145, 153, 177, 191, 205, 213, 214, 215, 216, 226, 230.
RB2 — The Real Book, Volume II: Becoming Is Being
Metabolic work sustains form through inputs and exported disorder. Rosen distinguishes component and energy production from repair while making them interdependent. Regulation can slow metabolism; closure does not secure foresight.
Occurrence locators: 9, 43, 44, 46, 121, 122, 126, 128, 130, 131, 168, 170, 173, 185, 194, 198, 218, 220, 221, 231, 237, 240, 255, 271, 290; Notes: 21.
RB3 — The Real Book, Volume III: Murmurations
Metabolism participates in living individuation and dissipation. Infrastructural metabolism names distributed supports, labor and offloaded costs of technical and institutional regimes.
Occurrence locators: 19, 20, 23, 25, 27, 32, 70, 72, 75, 79, 149, 150, 169, 285, 301, 318, 333, 343.
Background used in the editorial explanation
Domain-specific mechanisms and wider analogies remain distinguished. Original definitions retain their scope; local cross-references do not rewrite them. Named theories and mechanisms are distinguished from neighboring background, homonyms and the author’s own synthesis. Reproduced AI passages retain their separate voice.
