Editorial synthesis · provisional

Definition

Identity chiefly names an achieved continuity of form or organization through change, rather than possession of unchanging matter. The books distinguish this from logical self-identity, which PB and RB3 preserve, and from quantum individuality or private thisness. RB2 also reports IIT's identity of conceptual structure and experiential quality; RB3 separately examines civic identification as infrastructure. These are related words, not interchangeable claims.

Explanation

AB locates identity in maintained patterns, self-renewal and relations that help constitute their terms. PB expresses persistence through coherent isomorphism and coalgebraic behavior, while marking that identification interpretive and explicitly leaving the numerical law untouched. RB1's quantum discussion relocates empirical identity to transactional events and relational structure, without saying all discernment disappears. RB2's bacterium maintains bounded organization through material turnover; its IIT quotation instead postulates identity between conceptual structure and experiential quality.

RB3's No Self-Identity heading must be read with the epilogue's own distinctions: logical identity is not contested, diachronic persistence is a different problem, and quantum non-individuality concerns private thisness rather than an electron's being itself. Its synthesis presents identity as contextual achievement, while its notes acknowledge rival accounts of persistence. The epilogue also brings Simondonian surplus and Nishitani's relational emptiness into its metaphysical argument; those attributed views are not proofs that formal identity fails. Separately, civic identity infrastructure concerns access, traceability and contestability, not the persistence of a substance.

Scope and attribution

All five books own supported treatments. No Self-Identity is a qualified heading, not a denial of A = A. No alias is proposed for unconfirmed A ≠ A. The registered Principle of the Identity of Indiscernibles is not merged.

AB — The Actual Book

Identity lies in maintained working continuity despite replacement. Self-renewal achieves embodied identity; relations help constitute their terms.

PB — The Possible Book

The Tractatus preserves A is A while rejecting qualitative fixity and private quantum thisness. The categorical rendering uses coherent isomorphism and behavior, marked interpretive.

RB1 — The Real Book, Volume I: The Possible Is Real

Empirical particle identity arises through transactions and relational patterns, not enduring billiard balls. Joint-system differentiation survives within the structural-realist discussion.

RB2 — The Real Book, Volume II: Becoming Is Being

Circular self-production maintains the bacterium through turnover. IIT separately postulates conceptual structure as identical with experiential quality.

Occurrence locators: 5, 7, 18, 19, 20, 30, 32, 34, 35, 42, 43, 44, 45, 46, 47, 59, 81, 86, 88, 133, 147, 148, 149, 153, 157, 163, 164, 165, 170, 172, 173, 174, 177, 181, 182, 183, 184, 185, 186, 189, 190, 191, 192, 194, 195, 196, 197, 203, 205, 206, 207, 213, 223, 225, 227, 233, 236, 240, 242, 281, 287, 290; Notes: 212, 213.

RB3 — The Real Book, Volume III: Murmurations

The epilogue contests fixed substantial identity while preserving logical identity; notes distinguish persistence from quantum non-individuality and acknowledge rivals. Civic identification separately contrasts surveillance with minimal-data, contestable access.
