Melting Time (temps fondant)

David Morris's name (drawn from a Merleau-Ponty unpublished working note) for the indeterminate, invisible, undifferentiated change prior to time-orders that, through its own dynamics, generates visible, determinate time-forms. Morris's title formula: visible time expresses invisible change. The phrase temps fondant — usually translated "melting time" or "molten time" — is taken from a January 1959 working note in MP's BNF archive (vol. VIII, Notes 1958-1959, p. [253], titled "Janvier 1959. Pluralité des temps. Unicité du temps") that responds to the problem of unicity vs plurality of time. Morris extends the brief archival note into a full ontological-physical concept through engagement with quantum mechanics, Bergson, Smolin's temporal naturalism, and Aristotle's distinction between change and time-form.

Key Points

  • The base concept: changes on the level of temps fondant are not bound by time-orders, yet generate changes that manifest time-orders. There is real change without yet a manifest time-form.
  • Drawn from MP's archive: the phrase temps fondant and its connected notion of "ontogenesis of time" are from a Lefort-omitted working note (BNF vol. VIII p. [253]). The note is brief; Morris's interpretation is rich. The note is not in raw/; Morris is the wiki's first source for it.
  • Distinguishes change from time-form: change is the dynamical condition; time-form is the ordered, apparent time that emerges from change-dynamics distributing themselves. Aristotle's distinction (time as form of change) is the conceptual lever; Einstein's relativization (time-form not in soul or substance, but accessed only within changing dynamic relations as clocks) is the modern anchor.
  • Permits "achronic cosmoi": distinguishing change from time-form makes it conceptually cogent that change might proceed without enabling clocks. Cellular automata with sufficiently shuffled rules model this — random-shuffled game states approach indistinguishability from time-ordered states.
  • Empirically anchored in time-crystals: time-crystals (recently demonstrated quantum systems pumped at period $P$ that spontaneously break time-symmetry, oscillating at a different period) are the model of temps fondant generating a manifest time-form via "immanent law."
  • Morris's signature claim: matter is best reconceptualized not as spatial extension but as temporal change. Visible matter draws ultimately on invisible change.
  • Connects to institution: per *Institution and Passivity* 36/7, "time is the model of institution itself." Time "continues" only because it "was instituted," because it discontinuously erupted out of nothing. Temps fondant is what time is before it has been instituted — the indeterminate change-substrate from which institution erupts.

What the Concept Does

Temps fondant performs four argumentative jobs:

  1. It permits a non-spatial-realist ontology of quantum mechanics. Wavefunction realism (quantum states, pilot waves, many-worlds) reads QM dynamics as spatial distributions of states alongside the apparatus. QBism reads them as purely subjective probabilistic expectations. Morris reads them as temporal — what's distributed is change-dynamics as time-forms generated locally. Temps fondant is the ontological substrate of this temporal distribution: it is what the wavefunction indirectly indicates, namely a melting-time that change-dynamics distribute themselves out of.

  2. It rotates MP's structure-concept from spatial to temporal. *Structure of Behaviour*'s exemplars (soap bubbles, oil drops) operate via spatial redistribution. Morris argues MP's mature ontology requires reading the redistribution as temporal: structures distribute change-dynamics as time-forms, not forces as spatial forms. Temps fondant is what makes this rotation ontologically intelligible — it is the indeterminate change-substrate that structures redistribute themselves out of.

  3. It deforms Smolin's neo-Leibnizian temporal naturalism. Smolin's framework treats relational change-dynamics as monads (determinate identities) in a topological network with the rule of "maximize difference." Morris's temps fondant refuses determinate-identity bedrock: fundamental change is indeterminate being, not yet a determinate identity. This grounds Morris's deformation of Smolin's "maximize difference" into imperfecting-expression.

  4. It recovers Bergson's Matière et mémoire (1896) as proto-philosophy of QM. Bergson conceptualizes red light's two modes (wave / particle-as-contracted-vibrations) as a temporal duality — the protracted "when" of the wave vs the contracted past punching into the now as particle. Temps fondant names what Bergson's "contracted vibrations" emerge from: an undifferentiated change-substrate that contracts itself locally into qualitative effects.

What It Rejects

  • Time as substance / framework above change. Newton's absolute time with its own clock fixed above changes is the rejected position. Morris invokes Aristotle (Roark 2011, Sentesy 2020) and Einstein (DiSalle 2006, Weatherall 2016) to show that time-form is not in substance or transcendental subject but accessed only within change-dynamics manifest as clocks.
  • Time as transcendentally constituted by observer. Kant's a priori sequential time-form for causal understanding is also rejected (article note 6: Husserl's time-form inseparable from changing experiential materials). The point is that time-forms arise by and in change itself, not by transcendental synthesis.
  • Block-universe / timeless ontology. Time as an eternal manifold in which all events are simultaneously present is rejected (Smolin's foil Barbour's The End of Time). Temps fondant requires real change and real time-generation.
  • Pure-relational determinate-identity ontologies. Smolin's neo-Leibnizian monads in a topological network presuppose determinate identities at the base. Temps fondant refuses determinate-identity bedrock — the change-substrate is indeterminate being.
  • Wavefunction realism's spatial doubles. Pilot waves, many-worlds, quantum states as real distributions alongside the apparatus are rejected as spatial doubles invisibly paralleling what we observe. Temps fondant rotates the realism into time, not space.

Stakes

If temps fondant is accepted, three things change in the wiki's reading of MP and of physics:

First, late MP becomes a serious interlocutor for philosophy of physics, not just philosophy of perception or of life. The Lefort omissions (per morris-2024-wild-structure-melting-time §1) reveal MP pursuing ontology through QM and relativity — and the temps fondant note is the textual hinge that authorizes a reading of MP's mature ontology as a temporal ontology with serious physical-scientific stakes. This challenges the standard reception of late MP as turned away from the physical sciences.

Second, MP's "wild being" extends from biology / life to physics. The wiki's wild-being page is rich on the Lebenswelt, perception, animality, language, and the elemental tradition; what Morris adds is the application to subatomic physics. The qualifier "wild" applied to time (melting time) and to structure (wild-structure) is the diagnostic move: time and structures are "wild" insofar as they generate their orders rather than presupposing them.

Third, matter is reconceptualized as temporal change, not spatial extension. This is the deepest ontological inversion. The substrate metaphor is wrong: what carries quantum dynamics is not invisible spatial doubles but a temporal processioning (see processioning) — a deepening of the now into and out of its 'elsewhen' past. Temps fondant is the ontological substrate of this processioning.

The risks: the concept rests heavily on a single archival note (which Morris has not directly engaged in this paper); the "imperfecting expression" extension (see imperfecting-expression) is asserted rather than derived; the connection between temps fondant and time-crystals is analogical rather than demonstrative.

Problem-Space

Temps fondant addresses a recurrent problem at the intersection of phenomenology, philosophy of physics, and Bergsonian ontology: how can time be real and generative without being a fixed background? The classical attempts — Newtonian absolute time, Kantian transcendental time-form, block-universe timelessness — all fail in different ways: they make time prior to the dynamics whose manifestation they are supposed to enable. Bergson's durée answers this on the side of consciousness; Smolin's temporal relationalism answers it on the side of cosmology. Temps fondant answers it ontologically: time-orders arise from a deeper change-substrate that is itself not yet a time-order — but is also not nothing, since it has a dynamic, an impuissance, a "power of not-yet-being determinate change."

This problem-space recurs across MP's career under different vocabularies — institution as temporal eruption (1954-55), temporality of the living (1956-60 Nature lectures), original past that has never been a present (PhP 289), and finally the temps fondant note (January 1959). The recurrence under different vocabularies is what would warrant promotion of temps fondant to a problem-space-tagged concept page in the future, when more sources independently articulate the same problem.

Connections

  • is the substrate of ontogenesis-of-time — the local generation of time-orders out of temps fondant.
  • is the change-substrate of wild-structure — quantum systems read as MP-structures generate their time-forms by distributing change-dynamics out of temps fondant.
  • is operationalized by processioning — the temporal-distributive structure of QM dynamics whose carrier is temps fondant.
  • grounds (per Morris) imperfecting-expression — the imperfections of expression are constitutive of the indeterminate latitude that temps fondant affords being.
  • radicalizes MP's institution — IP 36/7 "time is the model of institution itself"; temps fondant is what time is before it has been instituted.
  • resonates with volant — Morris's ur-volant is time-form generated on the fly; temps fondant is what the ur-volant generates time-orders out of.
  • converges with wild-being — temps fondant is wild being in its temporal register, applied to physics rather than to biology / language. See claims#wild-being-extends-to-physics (live; created at the 2026-05-05 Phase 8 seventh run) for the corrective claim that late MP's wild Being is not turned away from physical sciences.
  • anchors claims#time-as-late-mp-privileged-ontological-clue (live, 2026-05-09; created at the 2026-05-05 Phase 8 seventh run) — the stronger Morris thesis that time itself is the privileged ontological clue in late MP. Promoted to live; standard reception still centers flesh-as-element.
  • anchors claims#quantum-systems-exhibit-merleau-pontian-wild-structure (candidate; created at the 2026-05-05 Phase 8 seventh run) — Morris's structural-parallel reading of QM phenomena as exhibiting Merleau-Pontian wild structure. Speculative cross-domain register.
  • is figured by the écart of time from change (see ecart) — Morris uses écart in passing for the divergence between change-dynamics and the time-orders they generate.
  • converges with Smolin's "unfreezing" of space-time backgrounds — but radicalizes against Smolin's residual Leibnizianism (determinate-identity monads).
  • converges with Wheeler's "volcanic time" and "law without law" — the contemporary physics analogues of MP's institution-as-eruption.
  • recovers henri-bergson's 1896 anticipation of wave-particle duality as temporal duality (MM 226, 230).
  • contrasts with Newtonian absolute time, Kantian transcendental time-form, block-universe timelessness.
  • exemplified empirically by time-crystals — quantum systems that spontaneously break time-symmetry, manifesting time-forms as expression of immanent change-dynamics.

Open Questions

  • Does the BNF January 1959 note actually authorize the rich reading? The note is brief — a single line title plus presumably some content (Morris does not transcribe it). Morris's interpretation is rich; whether the note itself bears the ontological weight Morris places on it is open. Direct archival engagement (e.g., Saint Aubert-style philological recovery) would clarify this.
  • Cross-source attestation. Morris is currently the wiki's only source for temps fondant. Confirmation from a second source (another late-MP scholar engaging the BNF archive on physics, or a physicist independently developing analogous concepts) would move temps fondant from confidence: medium / epistemic_status: novel toward higher confidence.
  • Relation to MP's Nature lectures on Bergson and Whitehead (merleau-ponty-2003-nature Course 1). Morris notes that MP "begins approaching this through Bergson and Whitehead on matter" in LN. The Nature extraction note has rich material on Bergson's "register of time" passage (Course 1, p. 62) and on Uexküll's melody figure; whether the temps fondant concept is anticipated in LN's published material (vs only in unpublished notes) is open.
  • The Whitehead question. Morris mentions Whitehead in passing (MP's LN engagement with Whitehead on matter) but does not develop the connection. Whitehead's process metaphysics is the obvious philosophical kin to Morris's temps fondant (events as becoming, time as constitutive). Morris does not address whether his temps fondant is structurally Whiteheadian or whether the convergence is coincidental.
  • The Born rule connection. Morris's note 11 says: "Where the many-worlds view gives reality to Schrödinger's wavefunction, this leap and disparity between the now and the past gives reality to the Born rule." This is a load-bearing technical claim about probability-density-as-squared-amplitude that Morris does not develop in the body of the article. What does it mean for temps fondant to "give reality to the Born rule"?
