Definition
A Gedankenexperiment, or thought experiment, uses an imagined or idealized situation to expose conceptual tensions, test explanatory assumptions, or focus practical judgment. Here Einstein's historical examples differ from the author's retrospective reconstruction of transactional physics, which offers an ontology without independently selecting it over rivals. RB3 also uses imagined ethical and technological situations while examining what their framing conceals.
Explanation
AB introduces Einstein's light-beam case and explicitly identifies the unfinished-emission scenario as the author's reconstruction, not Einstein's or Kastner's. Removing all receivers separates an independent-field picture from an exchange picture; it does not decide between them. The crystal scenario adds a comparison of relational individuation, not a proof that quantum physics and Simondon share one mechanism.
RB1 makes the methodological warrant explicit through Kuhn: exposing conceptual conflict also reorganizes available experience. It distinguishes historical ingredients from a claim that Einstein nearly derived RTI. Interference, environmental inhibition of emission and the divided-receiver consistency argument do not select RTI. The reconstruction reverses an explanatory priority rather than delivering a new prediction.
RB3 gives the method a different application. The trolley scenario concentrates responsibility at a lever but can conceal the regime producing that situation. The paperclip case diagnoses indifferent optimization rather than a clinical personality. The two-door scenario contrasts forms of correction to disclose selection pressures, explicitly declining to decide which door is correct. These are practical pressure tests, not extensions of the quantum demonstration.
Scope and attribution
Positive book ownership is AB, RB1 and RB3. PB and RB2 were reviewed but no direct thought-experiment treatment was established in the bounded searches. Historical method, retrospective reconstruction and ethical scenario are distinguished uses, not interchangeable evidential warrants.
AB — The Actual Book
The light-beam example introduces a method that the author borrows openly. The empty-universe reconstruction exposes a fork in assumptions, while the salt-crystal case supplies a comparison of relational emergence. Neither settles the physical interpretation.

RB1 — The Real Book, Volume I: The Possible Is Real
The retrospective reconstruction is grounded in Kuhn's account of conceptual conflict and carefully delimited historical materials. Its interferometer, empty-universe, divided-receiver and crystal cases constrain explanation without deriving RTI or producing a novel prediction. The comparison preserves differences between selection and individuation.

RB3 — The Real Book, Volume III: Murmurations
Thought experiments serve ethical and technological diagnosis. The trolley must be faced when imposed but is not the paradigm of ethics; the paperclip scenario concerns the organization of ends; the two-door scenario reveals selection dynamics without choosing a universally correct route.

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.
