Intra-Ontology (Indirect Ontology)

Merleau-Ponty's method-concept for an ontology that does not stand outside Being to describe it but operates within it — "Being in the beings." MP's formulation from the February 1959 V&I working note: "One cannot make a direct ontology. My indirect method (Being in the beings) is alone conformed with Being — 'negative philosophy' like 'negative ontology'" (V&I 179/231). The method-concept has a technical vocabulary of its own — infrastructure (membrure), hinge (charnière), jointing — that Chouraqui's 2014 reading isolates as the material register of intra-ontology. The cardinal formulation at V&I N 282: "Wild or brute being, contra sedimented-ontic being. Ontology which defines being from within and no longer from without: on every level, being is infrastructure, [membrure], hinge [charnière] and not offered in perspective and demanding the construal of what lies behind these appearances" (Chouraqui, Ch. 6).

Key Points

  • "Being in the beings" vs. direct ontology: MP's method refuses the Heideggerian stance that describes Being from outside it. Direct ontology is structurally impossible because the ontologist is already an event within what she describes. Intra-ontology names the acknowledgment of this — an ontology that includes its own operation within its object.
  • The technical vocabulary — hinge, membrure, charnière, infrastructure, jointing: these are MP's own terms for the mode of connection an intra-ontology seeks. Unlike "substance" (which names what-a-thing-is-in-itself) or "relation" (which names how-things-stand-to-each-other), a hinge or membrure names the joint that is internal to the thing it joins. It is not a bond between two things but the mode of a single thing's articulation.
  • The cardinal passage (N 282 / Chouraqui Ch. 6, raw line 1914): "Wild or brute being, contra sedimented-ontic being. Ontology which defines being from within and no longer from without: on every level, being is infrastructure, [membrure], hinge [charnière] and not offered in perspective and demanding the construal of what lies behind these appearances." This is MP's most compressed statement of the method — every level of being is already articulated as hinge/infrastructure, so no further "behind" is needed.
  • The Marx-genealogy: MP's use of membrure has a philological ancestor in the preface to *Signs*, where he quotes Marx on "the overlap [membrure] of the architectonic structure of history, of the merging of mind and matter, man and nature, and consciousness and existence" (S 6/14, cited in Chouraqui notes 2802). The membrure vocabulary enters MP's ontology from Marx's ontology-of-history.
  • The logical/ontological order distinction: Chouraqui reads MP's intra-ontology as resolving what he calls Nietzsche's "bad ambiguity" by separating two orders. Logically, beings come first (we access Being only through them). Ontologically, Being comes first (it is the infrastructure of the beings). This allows a phenomenology of ontology that takes its own object into account as a sedimentative event — see circulus-vitiosus-deus.

Details

Why "indirect"

MP's indirect method is not evasive or provisional; it is structural. Any direct ontology — one that attempts to describe Being from a vantage point outside Being — is inauthentic because there is no such vantage. The ontologist is always already an event within what she describes. Direct ontology is inauthentic because it pretends otherwise.

The intra-ontological alternative does not describe Being from outside. It describes beings (the available, the phenomenal) in such a way that Being's structure (hinges, infrastructure, membrures) shows itself through the description. The description is itself an event within the ontology it articulates. This is the "circle" of *circulus vitiosus deus* — the indirect ontology is circular because access to Being runs through the beings, while Being is the infrastructure of the beings.

The technical vocabulary: membrure, charnière, hinge

Chouraqui's Ch. 6 isolates the technical vocabulary MP uses when deploying intra-ontology. The cardinal citation from V&I N 282 (a working note, raw line 1914 in Chouraqui's book):

"Wild or brute being, contra sedimented-ontic being. Ontology which defines being from within and no longer from without: on every level, being is infrastructure, [membrure], hinge [charnière] and not offered in perspective and demanding the construal of what lies behind these appearances." (V&I N 282)

Three terms cluster here:

  • Infrastructure — what lies under the surface, but in a sense that does not presuppose "under-over": the infrastructure is the articulation of the thing itself, not a hidden foundation. (In the French: infrastructure retains its ordinary-language sense of an articulating framework, without the Marxist economic resonance, though see below.)
  • Membrure — the term of art MP borrows from architecture and anatomy. A membrure is the framework of a ship, the ribs of an umbrella, the load-bearing armature of a structure. It is articulated from within the thing it structures. The V&I 215/265 formulation: "the Visible itself has an invisible inner framework [membrure d'invisible] and the invisible is the secret counterpart of the visible" (Chouraqui notes 2988). The invisible is the membrure of the visible — not a separate layer behind the visible, but the articulation within the visible that lets it be a visible rather than an undifferentiated mass.
  • Charnière / hinge — an articulation that turns. A hinge has two leaves joined at a common axis; the two leaves belong to one body and rotate relative to one another. MP's hinge is the articulation of the reflexive body: "the body is the hinge of the for-itself and the for-the-other" (working notes, cf. chiasm §"Genealogy: From 'Hinge' to Chiasm"). The hinge joins without identifying, articulates without separating.

MP also uses jointing and montages in the same cluster. The V&I 197/248 formulation: "Being is what requires creation of us for us to experience it" — the creation (human experience, perception, expression) is the jointing through which Being is articulated. "The jointing and the hinge [membrure] of being [...] is being realised through man" (S 181/295, Chouraqui 2060).

The Marx Ancestor of Membrure

Chouraqui notes in a Ch. 6 endnote (raw line 2802) that MP's use of membrure has a philological ancestor in the preface to Signs:

"'The overlap [membrure] of the architectonic structure of history, of the merging of mind and matter, man and nature, and consciousness and existence'" (S 6/14)

This is MP citing Marx's 1844 Manuscripts (or paraphrasing Marx) in the Signs preface. The vocabulary of membrure is thus not a pure innovation of the late ontology but enters MP's late ontology from Marx's ontology-of-history. The structure MP names with membrure in Ch. 6 of V&I is the same structure Marx named as the "architectonic overlap" of history, mind-matter, man-nature, consciousness-existence. This connects the intra-ontological method to flesh-as-element's Marxist source (see What changes if flesh is already Marxist?).

The Logical vs. Ontological Order (Chouraqui Ch. 7)

Chouraqui's Conclusion and the Transition chapter develop the distinction that intra-ontology requires:

  • Logically, beings come first. We access Being only through the beings (perception, expression, other beings). If we try to describe Being directly, we are already drawing on beings as our evidence. Beings are the logical prius.
  • Ontologically, Being comes first. Being is the infrastructure, membrure, and hinge of the beings. The beings appear as beings against the background of Being. Being is the ontological prius.

This double order is what intra-ontology requires and what direct ontology collapses. Direct ontology posits Being as both logically and ontologically prior (we can "see" Being directly, then describe the beings from this stance). Husserl's Urdoxa and Heidegger's Seinsfrage both tend this direction. Intra-ontology preserves the ontological priority of Being while respecting the logical priority of the beings — we have to start from beings, even though Being is their infrastructure.

Chouraqui reads Nietzsche's "bad ambiguity" (the oscillation between taking the self as origin of will-to-power and taking will-to-power as origin of the self) as the philosophical problem MP's intra-ontology resolves. MP's logical/ontological distinction names what Nietzsche oscillated between: Nietzsche's self (logically prior) and his will-to-power (ontologically prior) are not rivals but two orders of the same structure. "Good ambiguity" is Chouraqui's name for this resolution.

Intra-ontology as "ontology of ontology"

Chouraqui's 2016 follow-up develops intra-ontology under the heading "ontology of ontology" — an ontology that must account for its own existence within the Being it describes. The double-circle structure:

  1. First circle — determination of beings (intentionality wandering between its poles in ordinary perception).
  2. Second circle — determination of Being (ontology sedimenting its own object).

Every point on the first circle is also a point on the second, because access to Being runs through the beings only. Intra-ontology is the method that acknowledges this double circularity — and the "hinge" / "membrure" / "infrastructure" vocabulary is the technical register in which the acknowledgment is conducted. Each of these terms names a point of articulation that is at once on both circles.

See circulus-vitiosus-deus for the detailed treatment of the double-circle structure and hyper-dialectic / hyper-reflection for MP's formal names for the same structure.

The Relation to the Chiasm and the Fold

Intra-ontology's vocabulary (hinge, membrure, charnière) is structurally continuous with chiasm and fold. The chiasm is a turning — hinge-like. The fold is an articulation within a continuum — membrure-like. The three concepts name one structure of intra-ontological articulation from three angles:

  • Intra-ontology (method): Being is articulated from within, through hinges and membrures.
  • Chiasm (phenomenology): the body's reflexive self-articulation is hinge-like.
  • Fold (ontology): Being's self-articulation as "mutual application of inside and outside" is the fold.

The hinge is the middle-term between the 1954–55 vocabulary of MP's Institution-Passivity course (where the body is explicitly a "hinge of the for-itself and the for-the-other") and the late-ontology vocabulary of V&I. See chiasm §"Genealogy: From 'Hinge' to Chiasm" and From hinge to chiasm for the genealogical line.

Connections

  • is the methodological signature of circulus-vitiosus-deus — the indirect method is circular because access to Being runs through beings. See claims#circulus-vitiosus-deus-mp-ontology-of-ontology (supported claim, promoted 2026-05-04) for the Nietzsche-MP genealogical reading anchoring this signature
  • has as its technical vocabulary hinge, membrure, charnière, infrastructure, jointing — the material register of Being's internal articulation
  • is the positive counterpart of shadow-philosophy — shadow philosophy reads other thinkers' intra-ontologies through their explicit philosophies; intra-ontology is the method MP himself performs
  • resolves Nietzsche's "bad ambiguity" into MP's good-ambiguity via the logical/ontological order distinction
  • has the Chiasm as its phenomenological form — see chiasm; the chiasm's reversibility is the hinge's operation at the level of perception
  • has the Fold as its ontological form — see fold-pli; the fold is how Being's self-articulation happens
  • is continuous with institution's "hinge" vocabulary — MP calls the instituting subject a "hinge between self and others" (Institution and Passivity, 1954–55). Institution is intra-ontology at the level of historical-passivity structure
  • draws its "membrure" vocabulary from Marx (1844 Manuscripts, via the preface to Signs at S 6/14) — the Marxist ontology-of-history is the philological ancestor of MP's intra-ontology vocabulary
  • contrasts with Heideggerian direct ontology — intra-ontology's "one cannot make a direct ontology" is explicitly anti-Heideggerian
  • contrasts with transcendental-idealist ontology (Husserl's) — intra-ontology does not posit a constituting subject outside the constituted

Open Questions

  • Does intra-ontology require the methodological circle (circulus vitiosus deus), or can the logical/ontological-order distinction be stated without it? Chouraqui 2014 treats the two as one move; Chouraqui 2016 formalizes the circle separately.
  • The membrure / charnière / hinge vocabulary comes from architecture and anatomy. Is this vocabulary philosophically load-bearing, or ornamental? Chouraqui treats it as load-bearing (the material register of Being's self-articulation); the alternative reading takes the vocabulary as merely illustrative of an underlying relational structure.
  • How does intra-ontology relate to Derrida's "always already" — both refuse a stance outside what they describe, but with different consequences. Chouraqui does not engage Derrida.
  • Is intra-ontology compatible with a form of realism about external objects? MP's "Being in the beings" does not commit to any particular realism — but the beings it accesses are phenomenal beings, so the question remains open.

Synthetic Claims

The synthetic interpretive layer (wiki/claims.md) articulates one supported claim for which this page is a Wiki home. Supported claims may be cited as stable synthetic claims without provisional framing per CLAUDE.md §Claims Register Format.

  • supported claim, see claims#circulus-vitiosus-deus-mp-ontology-of-ontology — Nietzsche's circulus vitiosus deus (BGE 56) is MP's only direct quotation of Nietzsche anywhere in his corpus, and the figure becomes architecturally load-bearing for MP's "indirect method (Being in the beings)" — the wiki's "ontology of ontology" reading. The claim is the philological keystone of the present page's account: intra-ontology is the wiki's name for the method-concept Chouraqui develops in Ambiguity and the Absolute and the 2016 Circulus Vitiosus Deus article, and the supported claim anchors the structural-figural register (hinge / membrure / infrastructure / charnière) in MP's specific Nietzschean appropriation rather than in a general philosophical reference. Promoted to supported 2026-05-04 under R8 user pre-authorization, after the Heidegger-mediation gap was discharged via the Heidegger Nietzsche I + II ingests.
