A living system does not simply persist through time — it persists by continuously producing the very components that constitute it, in a closed loop that never quite repeats itself exactly but never escapes itself either. Maturana and Varela's concept of autopoiesis describes precisely this: a cell, an organism, perhaps even a social system, is defined not by its boundary alone but by the fact that everything within that boundary is produced by the system's own operations — nothing enters from outside as a finished component, everything is metabolized, broken down, and reassembled according to the system's own internal logic. Luhmann took this further into the social register, arguing that social systems — law, science, economy — are similarly self-referential and operationally closed: a legal system does not import "justice" from outside but produces its own criteria for what counts as lawful, recursively, from its own prior operations, communication generating further communication in a loop that constitutes the system's only real environment. Read together, these accounts suggest that any sufficiently developed field — including a field of knowledge — begins to exhibit what might be called RecursiveAutophagia: a tendency to consume its own prior outputs as the raw material for new ones, citations feeding new citations, terms generating variations of themselves, the corpus folding back over its own history not as repetition but as digestion, each pass extracting something the previous pass left unprocessed. This digestive folding does not happen evenly across a corpus — it produces depth, accumulation, layers that retain their distinct character even as newer material settles on top of them, sometimes activating what lies beneath rather than replacing it. Bateson's account of mind as pattern, of information as "a difference that makes a difference," supplies the logic by which old layers remain active: a pattern laid down early in a system's history does not vanish when new patterns are layered over it, it persists as a constraint, a habit, a structuring absence that shapes how later patterns can form — mind, for Bateson, is precisely this accumulation of constraint across time, ecology as memory. A corpus organized this way might be described as a StratigraphicField: not a flat archive where every entry has equal and independent standing, but a layered formation where position in the sequence — what came before, what this entry presupposes, reactivates, or quietly contradicts — is itself part of the entry's meaning, the way a geological stratum's meaning includes its position relative to the strata above and below it. Simondon's account of technical objects undergoing "concretization" — becoming progressively more integrated, each part taking on multiple functions previously distributed across separate components — describes the same densification from the side of the artifact rather than the corpus: a technical object, like a stratigraphic field, becomes more itself, more coherent, more economical, through successive internal foldings rather than through addition of external parts. The Socioplastics project's own structure — Tomes built from Cores, Cores from Packs, Packs from nodes that increasingly cite, reactivate, and metabolize earlier nodes — exhibits exactly this double character: a recursive autophagia that does not exhaust the corpus but thickens it, and a stratigraphic field where Tome V's nodes are legible only in relation to the strata Tomes I through IV laid down beneath them, each layer a Batesonian constraint the next layer must work with or against.
