Cristallisation

Merleau-Ponty's cardinal anti-Sartre concept, appropriated from Stendhal's De l'Amour (1822) via Breton's L'Amour fou (1937). Cristallisation names the passive-active process by which the loved object (and, generalized, every perceived thing) takes on the surdétermined fullness that the lover (or perceiver) finds in it — a fullness that is neither projection nor objective property but the crystallization of the inépuisable. As Saint Aubert tracks in *Être et chair II* (Ch II § 4, Ch IV § 3), MP's cardinal formula is at NMS [136], autumn 1957: "mettre la notion de cristallisation à la place de celle de décision. C'est en cela que je me différencie de Sartre." The substitution of cristallisation for Sartrean décision names the single most concentrated divergence between the late MP and Sartre.

Key Points

  • Cardinal MP formula (NMS [136], autumn 1957): "mettre la notion de cristallisation à la place de celle de décision. C'est en cela que je me différencie de Sartre." The cristallisation replaces the décision as MP's name for what happens when a perceptual or affective field stabilizes.
  • Stendhal's source: De l'Amour (1822), where Stendhal describes the process by which the lover finds new perfections in the beloved as a crystallization — the salt-mine bough hung in the abandoned mine of Salzburg returns covered in scintillating crystals: not the bough's properties, not the lover's invention, but their reciprocal carnal-imaginal precipitation.
  • Breton's mediation: André Breton's L'Amour fou (1937) generalizes Stendhal's cristallisation amoureuse into a surrealist account of the hasard objectif — the world's cooperative-with-desire fullness that the surrealist captures. MP appropriates Breton's generalization without restricting to surrealism.
  • The MP genealogy: from love (ULL 1953, the cardinal Saint Aubert location for MP's first appropriation) → to the perceived thing in general (PbPassiv 1955) → to the ontological cristallisation of EM2 149 and DESC 120 (1959–60). MP universalizes Stendhal-Breton to the entire ontology of perception.
  • "Matérialisme onirique": Saint Aubert's formula for MP's triad cristallisation / concrétion / précipité — three names for the same process by which the perceptual field takes solid form without losing its onirique register. The cristallisation is not crystal-as-determination but crystal-as-precipitation (cf. OE p. 19–20 on cristal-eau-mère).
  • Anti-Sartre, but specifically anti-décision: The Sartrean décision is the act of consciousness that institutes its world by choosing a perspective and committing to it. MP's cristallisation is what happens prior to and beneath any decision — the perceptual-affective field stabilizes without an act of choice, through the passive-active coupling of flesh and being. The contrast is exact: décision as the form of liberté prénatale; cristallisation as the form of being-already-borne- into-the-world.

Details

The Stendhal-Breton genealogy

Saint Aubert (Ch II § 4) traces the literary genealogy with care. Stendhal's De l'Amour (1822) coins cristallisation in the famous salt-mine analogy:

"Aux mines de sel de Salzbourg, on jette dans les profondeurs abandonnées de la mine un rameau d'arbre effeuillé par l'hiver; deux ou trois mois après on le retire couvert de cristallisations brillantes. (...) Ce que j'appelle cristallisation, c'est l'opération de l'esprit, qui tire de tout ce qui se présente la découverte que l'objet aimé a de nouvelles perfections." (Stendhal, De l'Amour, ch. 2)

The structure is exact: a bare branch (the inert object) becomes scintillant through immersion in a milieu (the salt mine, charged with desire). The crystals are not properties of the branch (the branch alone has none) and not properties of the salt (the salt alone has no figure); they emerge from their carnal-temporal contact.

Breton's L'Amour fou (1937) takes Stendhal's process out of psychology and into ontology: the world itself is structured by cristallisation, and the surrealist trouvaille (the found object, the chance encounter) is the world's cooperation with desire. MP silently inherits Breton's generalization — the world crystallizes desire in the perceptual field, not just in love.

MP's appropriation: from love to ontology

MP's first attested appropriation is in Université populaire de Lyon (ULL 1953), the love-course. There the cristallisation is still a phenomenology of love — the loved person is crystallized out of the perceptual field of the lover, with reciprocal crystallization in the loved.

The decisive move is at NMS [136] (autumn 1957). MP universalizes: cristallisation replaces décision as the model for what happens when a perceptual or affective field stabilizes. The Sartrean décision — the act of consciousness that institutes its perspective — is rejected as a survol model. The cristallisation model is non-survol: the perceiver does not choose the field; the field crystallizes through their carnal participation.

By 1959–60 (EM2 149, DESC 120) the cristallisation has become ontological: every perceived thing is a cristallisation of the inépuisable. The thing is not given fully (Husserl's Erfüllung) and not posed by consciousness (Sartrean décision); it is crystallized through the carnal-temporal coupling of flesh and being.

"Matérialisme onirique"

Saint Aubert's name for MP's triad: cristallisation / concrétion / précipité. All three are figures from chemistry-mineralogy that MP deploys against Sartre's polarized real-imaginary ontology:

  • Cristallisation: the form-taking of the perceptual field.
  • Concrétion: the growing-together of disparate elements into a perceived unity (cf. Whitehead, but MP's use is independent).
  • Précipité: the falling-out of a determinate figure from a saturated solution.

The three names share a structure: form emerges from below, not from above. The perceived is precipitated from the carnal- sensible solution, not imposed by an act of consciousness.

This is what Saint Aubert calls "matérialisme onirique": a materialism that is also a dream-thinking — the figures emerge from a milieu that is at once material (the perceptual field) and oneiric (saturated with desire and the inexhaustible). See onirisme (when created) for the broader register.

Against Sartre's décision

The Sartrean décision is the act of consciousness that institutes its world by choosing a perspective. The structure presupposes:

  • A consciousness prior to its world.
  • An en face posture from which the world can be chosen.
  • A toute-puissance of the choice (cf. folie de la conscience, the shared Descartes-Sartre disease — see idole).

MP's cristallisation refuses each:

  • The perceiver is not prior to the perceived; they crystallize together.
  • The posture is non-survol: the perceiver is implicated in the field they crystallize.
  • The cristallisation has no act-character — it is what happens when a field stabilizes, not what someone does.

NMS [136] cites this as the precise locus of MP's divergence from Sartre: not on the content of any particular ontology, but on the model of how a world becomes determinate.

The ontological cristallisation (1959–60)

Two cardinal occurrences in late manuscripts:

  • EM2 149: ontological cristallisation of being.
  • DESC 120: cristallisation in the Cartesian-scenario manuscripts, where MP works out the alternative to Cartesian idée claire et distincte.

By this point the cristallisation has become a general ontological operator: every determinate being is a cristallisation of the inépuisable. This connects to the ultra-chose thesis: every thing is ultra-chose and every thing is cristallisation. The two formulas name the same structure from opposite sides — the ultra-chose is what exceeds the cristallisation; the cristallisation is what emerges from the ultra-chose.

Cardinal evidence

"mettre la notion de cristallisation à la place de celle de décision. C'est en cela que je me différencie de Sartre." (NMS [136], autumn 1957)

"Aux mines de sel de Salzbourg, on jette dans les profondeurs abandonnées de la mine un rameau d'arbre effeuillé par l'hiver; deux ou trois mois après on le retire couvert de cristallisations brillantes." (Stendhal, De l'Amour, ch. 2)

"Pourtant j'ai admis dans Phénoménologie de la perception l'ambivalence de l'imaginaire et du réel." (EM2 [223]v, 16 juin 1959) — MP's acknowledgment that PhP was not yet free of Sartre's bifurcation. The cristallisation thesis is the post-PhP answer.

"L'être et l'imaginaire sont pour Sartre des 'objets', des 'étants' — Pour moi ils sont des 'éléments' (au sens de Bachelard)." (NT p. 320, nov. 1960) — MP's most concentrated formulation of the alternative ontology within which cristallisation operates: being and imagination as éléments (Bachelard), not objets (Sartre).

Positions

  • saintaubert-2021-etre-et-chair-ii is the principal source for the philological reconstruction. Saint Aubert's tracking of the Stendhal-Breton-MP genealogy (ULL 1953 → NMS 1957 → EM2 / DESC 1959–60) is the wiki's primary anchor for the concept. The "matérialisme onirique" formula is Saint Aubert's.
  • Earlier MP scholarship treated cristallisation in MP as a scattered figure rather than as a structural concept. The cardinal NMS [136] formula was unpublished until Saint Aubert's archival work made it available.
  • Stendhal scholarship focuses on the love-context of the cristallisation; Breton scholarship focuses on the surrealist hasard objectif. Saint Aubert's contribution is to track how MP's philosophical appropriation runs through both without reducing to either.

Connections

  • replaces (per NMS [136]) the Sartrean décision — MP's most concentrated point of divergence from Sartre.
  • operates within the *texture imaginaire du réel* — the cristallisation is how the imaginary textures the real.
  • is the form-taking of the ultra-chose — every determinate thing is a cristallisation of the inépuisable.
  • parallels prégnance — both name the process by which the perceived stabilizes without being posed.
  • is rehabilitated by hyper-objet — Saint Aubert's own rehabilitation of the objet register against MP's diabolisation: the hyper-objet is precisely the cristallisation du désir MP risked losing.
  • contrasts with idole — the idole is the false crystallization (figure-without-fond, totally posed); the cristallisation is the true form-taking (figure-with-fond, emerging from below).
  • operates through flesh — the cristallisation is the carnal-imaginal precipitation of the perceptual field.
  • is part of the triad cristallisation / concrétion / précipité (Saint Aubert's "matérialisme onirique").
  • is sourced in andre-breton's L'Amour fou (1937) and Stendhal's De l'Amour (1822).

Open Questions

  • The Stendhal–Breton genealogy is well-traced for cristallisation itself; the extension to concrétion and précipité in MP is Saint Aubert's reconstruction. Are these three figures philosophically equivalent or do they do distinct work?
  • Does MP's silent borrowing of Breton extend to the surrealist hasard objectif? Saint Aubert is cautious; MP cites Breton on L'Amour fou in scattered places but never on the hasard objectif directly.
  • The 1959–60 ontological cristallisation seems to converge with Whitehead's concrescence — is the convergence accidental or philological? MP read Whitehead but did not, to Saint Aubert's knowledge, cite him on this point.
  • How does cristallisation relate to MP's later institution? Both name form-taking without constitution; the cristallisation is more passive-perceptual, the institution more sediment-historical.
