Ontologie de l'objet

Merleau-Ponty's cardinal late-period polemical category — the ontologie de l'objet names any ontology that treats being on the model of the frontal observable object. The unifier behind Descartes, Kant, Sartre, and Piaget is not their disagreements but this shared assumption that what is is what can be posed en face, surveyed, and made fully present. Saint Aubert's philological finding: the phrase "ontologie de l'objet" first appears in MP's La Nature ou le monde du silence (NMS, autumn 1957), runs through EM1 (autumn 1958), and structures the published V&I. The ontologie de l'être vertical is its counter-name — and the late ontology of figuratifs, flesh, and the visible-invisible is the working-out of the alternative.

Key Points

  • First philological occurrence: NMS 28–[28]v(8), autumn 1957, on Sartre-Descartes-Kant: "cette ontologie est devenue en nous institution" (cited Saint Aubert 2021, Le scénario cartésien fn p. 34). NMS is the first MP text to use the precise formula "ontologie de l'objet."
  • The unifying frame, not the differences: MP groups Descartes, Kant, Sartre — and surprisingly Piaget — as sharing a single ontological commitment: being is what can be made frontal, observable, fully posed. Their philosophical disagreements are internal to this ontology; the late MP refuses the ontology itself.
  • Polemical pair: ontologie de l'objet vs. ontologie de l'être vertical. The vertical-being ontology refuses the survey position from which an object can be posed — it thinks being from within perception's écart, not from above it.
  • What "objet" means in this technical sense: not "thing" in the ordinary sense (a chair, a stone), but the correlate of survol — what is given to a consciousness that takes itself out of perceptual implication. Hence even flesh can be objectified, and even the soul can be an objet (in Cartesian dualism).
  • The five "hypercartésiens": Saint Aubert's diagnostic — Sartre, Descartes, Kant, Piaget, and (in a different register) Husserl share the ontologie de l'objet despite their oppositions. This is MP's most ambitious unification of his polemical targets.
  • Cardinal counter-formula (NLVIaf2 [149], spring 1959): "Ce n'est pas par l'être et le néant que nous pouvons comprendre cela. C'est par cela que nous pouvons comprendre l'être et le néant." The ontologie de l'objet starts from being and néant; the late MP reverses the order of explanation.

The Chapsal 1960 public attestation

The wiki's primary archival anchor (NMS 1957) is matched by a public, first-person MP attestation in the Chapsal interview of 1960 — published 1960 in Les Ecrivains en personne (Julliard). Asked about ontology, MP names both the position and its target:

"One of the important ontologies of the West treats the visible world as the only possible manifestation of an infinite productivity. If something had to be, it could not be other than this world. Being is thus conceived as full being [être plein]. There is not a trace of wavering, it manifestly could not be otherwise. It has the solidity of the object." (Chapsal, p. 34)

"Catholicism, for example, is closely tied to the ontology of the object. . . . Atheist or not, [our best students] know all too well that neither the philosophy of the Enlightenment, nor marxism, nor the philosophy of ens realissimum is the truth." (Chapsal, p. 35)

The Chapsal interview makes three points the archival texts only partially reach: (a) MP himself uses the phrase "ens realissimum" (the scholastic-Cartesian-Leibnizian topos) as an alternate name for the same polemical category; (b) MP groups Catholicism, Enlightenment philosophy, and Marxism as forms of the ontology of the object — extending Saint Aubert's archival list (Descartes-Kant-Sartre-Piaget) to include the political-religious institutional forms; (c) the alternative MP names is "philosophy of brute being" — directly tying ontologie de l'objet to its anti-pole brute being in MP's own first-person voice. The Chapsal attestation therefore confirms and extends Saint Aubert's archival reconstruction with a 1960 public-print anchor that is not derivative of any of MP's published philosophical works (PhP, Signs, V&I) but is a separate genre of exposition for a non-academic public.

The NMS 1957 origin

The La Nature ou le monde du silence manuscript (autumn 1957), unpublished until Saint Aubert mined it, contains the inaugural use of "ontologie de l'objet." The context is MP's unification of Sartre, Descartes, and Kant under a common diagnosis:

"Que l'être doive être ainsi défini d'emblée, dans le halo d'une liberté qui le trouve comme être absolu précisément parce qu'elle- même n'est rien, cela ne va pas de soi, mais nous avons oublié que cette manière de l'envisager a sa date historique et ne s'impose pas à toute philosophie possible. (...) cette ontologie est devenue en nous institution." (NMS 28–[28]v(8))

The diagnostic move: the ontologie de l'objet has a historical date (Cartesian) and is not philosophically necessary. It has become institution in MP's technical sense (cf. institution) — sedimented as the very form of philosophical questioning. The late ontology must therefore work behind the institution, in the register of the unobservable that the ontology of the object cannot pose.

The shared assumption of the targets

The unification cuts across what would seem to be opposed positions:

  • Descartes: being is the correlate of clear and distinct understanding (cf. idole: the idée claire et distincte as paradigm of the objet).
  • Kant: being is the correlate of the transcendental object as unifier of judgments.
  • Sartre: being is the En-soi — "plénitude absolue et entière positivité" (L'Être et le Néant p. 50, the formula that anchors MP's entire late Sartre-critique). The negative is exterior to being.
  • Piaget: being is the objet permanent — the developmental achievement that converts perceptual residue into observable thing.

Each of these is a form of the ontologie de l'objet despite their mutual disagreements. What the late MP refuses is the common form, not any one position.

The polemical pair: ontologie de l'être vertical

MP's counter-name for his own ontology. The vertical register is the depth-direction of perception — the dimension that is not posed en face but inhabits the figure-ground structure of every perceptual act. Cardinal text: VI4 p. 196–198: profondeur as "l'invisible de ce monde, celui qui l'habite, le soutient et le rend visible, (...) l'Être de cet étant" — being as the figuratif of the visible, not its frontal correlate.

For the late MP:

  • Ontologie de l'objet = being as what can be observed.
  • Ontologie de l'être vertical = being as what makes observation possible without itself being observable.

The shift names what Chouraqui formalizes as the move from epistemological to ontological treatment of the question of truth: the late MP's verticality is what survives the critique of survol.

The Sartre-as-paradigm (Ch I §§ 2–3)

Saint Aubert tracks how MP unifies the Sartre-scenario across three manuscripts (NMS 1957 → EM1 1958 → NPVIf 1959), each generalizing:

  1. NMS (autumn 1957): from liberté to Nature — the ontology of the object as the inheritance of a "Cartesian institution."
  2. EM1 (autumn 1958): from Nature to rapport de l'être et du néant — the ontology of the object as the form of the en-soi / pour-soi opposition.
  3. NPVIf / NLVIaf2 (spring 1959): feeding into VI Ch 2 Interrogation et dialectique — the ontology of the object as what hyperdialectique refuses.

The convergence closes with the ambivalence/ambiguïté distinction: ambivalence is the form of intra-objectual oscillation; ambiguïté is the sortie via the third term that the ontology of the object cannot pose.

The Piaget surprise

The most distinctive of Saint Aubert's groupings: Piaget joins Descartes-Kant-Sartre as a hypercartésien. Why? Because Piaget's genetic epistemology treats the objet permanent — constructed through representation around 18 months — as the developmental achievement of the child's cognitive maturation. The perceptual residue that resists construction (the ultra-chose) is for Piaget a defect to be overcome. For MP via Wallon, the same residue is the positive ontological mode of every perceived thing.

Piaget is therefore the developmental form of the ontologie de l'objet — the genetic-epistemological version of the same Cartesian commitment. See ultra-chose for the cardinal contrast.

Why the critique cannot be merely epistemological

A central thesis of Saint Aubert: the ontologie de l'objet is not a mistaken theory about being but a sedimented form of philosophical attention. To refuse it requires more than a different theory — it requires a different practice of philosophy. Hence the late MP's:

  • Choice of the cours form over the treatise.
  • Use of figuratifs (fond, ombre, horizon, profondeur, silence) rather than figures.
  • Deployment of hyper-dialectic / hyper-reflection as practices, not theses.
  • The choice of chair (a figure from the mother tongue) rather than a neologism.

The form of MP's late writing is itself an answer to the ontologie de l'objet — the writing performs what a treatise about an alternative ontology would re-objectify.

Cardinal evidence

"L'analytique de l'Être et du Néant, c'est le voyant qui oublie qu'il a un corps." (VI2 p. 108)

"Ce n'est pas par l'être et le néant que nous pouvons comprendre cela. C'est par cela que nous pouvons comprendre l'être et le néant." (NLVIaf2 [149], spring 1959)

"Prendre comme premier, non la conscience et son Ablaufsphänomen avec ses fils intentionnels distincts, mais le tourbillon que cet Ablaufsphänomen schématise, le tourbillon spatialisant- temporalisant (qui est chair et non conscience en face d'un noème)." (NT, p. 297–298, avril 1960)

The third quote names the cardinal anti-Husserl move: even Husserl's intentional analysis is a form of the ontologie de l'objet because it keeps the en face posture (consciousness facing its noema). The late MP wants the tourbillon — the swirl of flesh and being — prior to the en-face structure that intentionality presupposes.

Positions

  • saintaubert-2021-etre-et-chair-ii is the principal philological reconstructor of the concept. The NMS 1957 first use is Saint Aubert's discovery (cited at Le scénario cartésien fn p. 34). The unifying scope (Descartes-Kant-Sartre-Piaget) is Saint Aubert's diagnostic.
  • Chouraqui 2014 treats the same critique under his "phenomenon of truth" framework: the ontologie de l'objet is what cannot survive the critique of holding-true, since holding-true requires the écart that the object-ontology forecloses. The two readings are compatible — Saint Aubert philologically anchors what Chouraqui formalizes.
  • Earlier interpreters (Barbaras, Dastur) treated MP's anti-Sartre polemic without naming the unifying ontologie de l'objet category. Saint Aubert's contribution is to elevate the category itself as the late MP's polemical concept.

Connections

  • targeted by hyper-dialectic — the bonne dialectique is the practice that refuses the survey-position the ontologie de l'objet presupposes.
  • targeted by figuratifs — being-as-figuratif refuses being-as- figure, the ontological form of the objet.
  • contrasts with ontologie de l'être vertical — MP's counter-name (currently treated within figuratifs and flesh).
  • paradigmatically targets idole — the idole is the figure-without-fond, the perceptual-ideological form of the objet.
  • unifies MP's anti-Sartre, anti-Descartes, anti-Kant, and anti-Piaget polemics under a single category.
  • operates through ambiguïté vs ambivalence — ambivalence is the intra-objectual oscillation; ambiguïté is the sortie the ontologie de l'objet cannot pose.
  • is critiqued by hyper-objet — Saint Aubert's own concept partially rehabilitates the object-register against MP's diabolisation, restoring the cristallisation du désir MP risked losing.
  • is the institution behind the *texture imaginaire du réel* — Sartre's L'Imaginaire depends on the ontologie de l'objet to separate image from real.
  • is what Chouraqui's intra-ontology cannot be — intra-ontology is non-objectual by formal necessity.
  • is replaced (not extended) by a three-term ontology in the Saint Aubert reading — see claims#ontologie-de-la-chair-misnomer (live claim) and claims#etre-not-monde-but-rends-sensible-monde (live); MP's late counter-ontology is notre chair / le monde / l'être, where l'être makes the world sensible without coinciding with either chair or monde.

Synthetic Claims

  • live claim, see claims#chapsal-1960-public-anchor-for-ontology-of-object-rejection — MP's 1960 Chapsal interview supplies a public, non-archival, first-person anchor for MP's rejection of "ontology of the object" — predating Saint Aubert's archival reconstruction. MP names ens realissimum and "ontology of full being [être plein]" as the position he rejects in his own first-person voice (Chapsal pp. 33–35). The claim re-grounds this page's polemical-target framing as MP's own self-presentation rather than as Saint Aubert's interpretive imposition. Promoted candidate→live 2026-05-09 under twelfth Phase 8 run user pre-authorization. The Saint Aubert archival reading remains the deeper philological resource; the Chapsal text supplies a complementary, not substitutive, anchor (per the entry's Counterpressure §3).
  • live claim, see claims#etre-not-monde-but-rends-sensible-monde — the ontology of the object is what the strict anti-monism rejects: MP's être is not the world (monde) but what makes the world sensible, and the ontologie de l'objet conflates être with the frontal-observable monde it purports to explain.

Open Questions

  • Does the unification of Husserl with Descartes-Kant-Sartre (via the en face structure of intentionality) overstate the case? Husserl's later genetic phenomenology arguably moves toward a non-objectual register (passive synthesis, Lebenswelt) that the early analytic of intentionality did not.
  • Is the ontologie de l'objet category itself an instance of the ontology it diagnoses? Naming a form of philosophy and then opposing it could be precisely the kind of frontal posture the category names. (See the analogous worry on good-ambiguity: the distinction itself risks the bad ambiguity it diagnoses.)
  • Saint Aubert's surprising inclusion of Piaget — is the parallel more than analogical? Piaget's developmental program differs in register from Sartre-Descartes-Kant; the unification is illuminating but should be tested against Piaget's own writings.
