John Archibald Wheeler

American theoretical physicist (1911-2008). Doctoral advisor to Richard Feynman; collaborator with Niels Bohr; coined "black hole," "wormhole," and "it from bit." Wheeler is the originator of the delayed choice experiment that has become one of the cardinal cases for ontological interpretation of quantum mechanics — and he is, on Morris's reading, "a very philosophically minded physicist" whose conception of time as "volcanic" and "law without law" "echo Merleau-Ponty's concepts of discontinuity or institution" (Morris 2024, p. 159).

Key Points

  • The delayed choice experiment. A single photon passes through a beam splitter, then reflects off mirrors, then traverses (or does not) a second beam splitter before reaching detectors. With one splitter the photon registers as particle (random direction); with two it registers as wave (self-interfering). Adding the second splitter after the photon would have already passed the first does not change the result — even in cosmic setups using photons from billions-of-years-old galaxies. The experiment is the cardinal challenge to any reading that takes the photon as determinately particle or wave at all moments.
  • The "great smoky dragon" image. Wheeler's metaphor for the photon: "The mouth of the dragon is sharp, where it bites" (the detector); its tail "is sharp, where the photon starts," but "What the dragon does or looks like in between we have no right to speak" — the dragon is smoke. Morris reads this as Merleau-Ponty's indeterminate being.
  • "Volcanic" time and "law without law." Wheeler's late writings on time include the conception of time as volcanic (eruptive rather than continuous flow) and the "law without law" thesis (the universe lacks a fundamental law-substrate; lawful behavior emerges from a law-less ontological ground). Both ideas — per Morris — echo MP's conception of institution as discontinuous eruption from nothing and of structures as generating rather than presupposing their orders.
  • "It from bit." Wheeler's late conception that all physical reality is informational at base. Not directly relevant to Morris's reading but contextually important for situating Wheeler's philosophical commitments.

Wheeler in Morris's Reading

Morris uses Wheeler in three ways:

  1. As empirical anchor. The delayed-choice experiment is the cardinal phenomenon Morris's "wild structure" / "processioning" interpretation needs to account for. Wheeler's experimental setup, with its cosmic-scale extensions, makes the standard interpretive moves (particle on path / wave on paths / backward-in-time signal) untenable.

  2. As interpretive metaphor. The "great smoky dragon" image is Morris's authorization for reading the photon "in between" tail and mouth as MP's indeterminate being. Wheeler explicitly says "we have no right to speak" of what the dragon does in between — and Morris reads this silence as the ontological status of indeterminate being, not as epistemic limitation.

  3. As philosophical kin to MP. Wheeler's "volcanic time" and "law without law" are presented as concepts that, on the surface, sit far from continental phenomenology — but, on inspection, articulate something close to MP's institution-as-eruption and structure-as-law-generating. The kinship is not derivative; it is convergent.

Connections

  • originator of the delayed choice experiment — central to wild-structure and to morris-2024-wild-structure-melting-time §2.
  • coiner of the "smoky dragon" image — used in wild-structure §"What It Rejects" as the metaphor for indeterminate being.
  • converges with MP on discontinuity / institution — see institution for the MP-side of the convergence.
  • converges with melting-time — "volcanic time" as a contemporaneous physical conception of time-as-eruptive.
  • contrasts with Smolin's framework — Wheeler's "law without law" is more radically anti-substrate than Smolin's neo-Leibnizian monads. Morris does not develop this contrast but the philosophical distance is real.

Open Questions

  • Direct ingest of Wheeler 1983b "Law Without Law" would let the wiki engage Wheeler without Morris's mediation. This is one of the most philosophically loaded papers in late-20th-century physics.
  • Volcanic time vs. melting time. Morris claims Wheeler's "volcanic time" "echoes" MP's discontinuity and institution. But the relation between Wheeler's volcanic time and Morris's temps fondant (drawn from MP's January 1959 unpublished note) is itself worth investigating. They are similar in valence but possibly different in structure.
  • Wheeler and Bohr. Wheeler was Bohr's collaborator; the smoky-dragon image is presented in Miller-Wheeler 1984 in the context of "Bohr's Elementary Quantum Phenomenon." How much of Wheeler's interpretive framework is Bohrian? The Copenhagen-vs-late-Wheeler relation is not addressed by Morris.
