Definition

Potentia names possibility as real rather than merely a description of ignorance. AB introduces its Aristotelian sense through the acorn's capacity to become an oak; the quantum use concerns physically effective possibilities prior to actualization. In Kastner's restricted sense, a prepared or emitted quantum state qualifies, not everything permitted by physical law. Broader philosophical uses must remain distinguishable from that restriction.

Explanation

AB traces the word from Aristotle through Heisenberg to Kastner, while criticizing the picture of potential as a script enclosed within an actual thing. Its quantum account treats unrealized possibilities as effective, but expressly limits Kastner's potentia to a prepared or emitted state not yet absorbed. Functional-information comparison spaces are not thereby quantum potentia.

RB1 contrasts res potentia with actual spacetime events through Kastner's yarn-and-fabric analogy. Its technical account excludes merely conceivable and merely law-consistent alternatives. Its broader Potentia heading introduces Simondonian individuation rather than identifying every preindividual potential with a quantum state. PB invokes Heisenberg's term for real propensities and maps the quantum sea metaphor onto poetic composition; that mapping is an analogy.

RB2 distinguishes the field of real possibility, the interface of actualization and the growing spacetime record. RB3 makes the same distinction while warning that resonance with the preindividual is not identity or proof. It also separates real quantum possibility from what can actually complete a transaction under given conditions, and excludes imagined unicorns from res potentia.

Scope and attribution

All five books have direct support. The historical use is AB-owned; the broader philosophical extension is locally grounded in PB, RB1 and RB3, not a redefinition of Kastner's technical restriction. No alias to the existing field-of-potential entry is proposed.

AB — The Actual Book

AB distinguishes the acorn's in potentia from physically effective quantum possibilities and restricts Kastner's term to prepared or emitted states not yet absorbed. It denies that functional-information comparison spaces prove or instantiate the quantum ontology, and calls the convergence with Simondon suggestive rather than demonstrative.

PB — The Possible Book

PB names real propensities potentia in its Tractatus. Its composer's note explicitly maps a quantum sea, actualization crest and spacetime wake onto the unwritten, writing and written. This is a local literary application, not a claim that poems are quantum states.

Occurrence locators: 90; Notes: 41.

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

RB1 gives both a broad Potentia heading for individuation and a restricted quantum account. Res potentia is contrasted with actual events in the knitting analogy. The technical restriction excludes merely law-consistent alternatives; the vacuum example concerns a physically efficacious non-spacetime Hilbert-space state, not an empty classical container.

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

RB2's potentia belongs to the quantum field of real possibilities, not the past archive. The eternal present names the interface of actualization, not a global instant or a third mode beside possible and actual. Completed events enter the growing spacetime record.

RB3 — The Real Book, Volume III: Murmurations

RB3 treats quantum potentia as an analogue of the preindividual while denying identity and proof. Its broader ontological use of potential is distinguished from both nomological possibility and Kastner's prepared/emitted states. A real possibility need not be actualizable under given conditions, and an imagined unicorn is not res potentia.
