Coexistence

Merleau-Ponty's term in Phenomenology of Perception for the structural togetherness of bodies, points, sensations, and selves that is not built up from prior atomic units but is presupposed in the unity of any experience. Coexistence names what intercorporeity is the structure of and what Mitsein gestures toward without quite reaching: a being-with that is not added to perception or to the body but is already operative in them. The term is silent in PhP — used 12+ times across multiple chapters, never definitionally thematized — but anchors the aphonia chapter of Part Two, where the patient's symptom is named "a refusal of coexistence."

Key Points

  • Coexistence in PhP is not the bare fact of being-alongside-others; it is a positive structural feature of perception, of the body, and of the historical world. Sensation itself is "coexistence or communion" between the sensing subject and the sensed quality (raw line 3024).
  • It is presupposed in the unity of bodily and perceptual experience: three points A, B, C "coexist before our eyes" (raw line 1403); Schneider's "coexistence of the tactile givens with the visual givens" is what is destroyed in his disorder (raw line 2245).
  • The aphonia chapter (Part One Ch V — Sexuality, raw lines 2603–2632) names the patient's symptom as "a refusal of coexistence." Recovery is described as the body "again open[ing] to others or to the past, when it allows itself to be shot through by coexistence." The chapter makes coexistence the load-bearing term for what aphonia removes and what therapy restores.
  • Coexistence is what Schneider lacks at the level of speech: another's words are for him "merely the opportunity for a methodical interpretation" because they are "devoid of the primordial signification obtained through coexistence" (raw line 2380).
  • In Part Three on history, coexistence carries economic and political weight: "even within coexistence, some period of history can be considered as above all cultural, or primarily political or economic" (raw line 2702). Marx's Mitsein and PhP's coexistence are aligned but the latter is broader.

Details

What coexistence is not

Coexistence in PhP is consistently distinguished from three nearby notions:

  • It is not Husserlian Paarung (analogical pairing of egos). PhP rejects the Husserlian apparatus of Cartesian Meditation V; coexistence is not built up by analogy from the self's experience of its own body.
  • It is not Heideggerian Mitsein in the strict sense. Mitsein is referenced (in the discussion of Marx, line 2688: "are not economic relations expressed in the mode of Mitsein?") but coexistence is broader than the existential structure Heidegger names: it covers sensation, the body's relation to its parts, the relation between perceived points, and intersubjectivity proper.
  • It is not Sartrean opposition through the Look. The Sartrean Other is given through conflict; PhP's Other is given through a coexistence already in place.

The aphonia chapter — coexistence's most load-bearing deployment

Part One Ch V (Sexuality and the body's expression — sometimes filed under Ch VI in some translations) treats the case of a young woman whose mother has forbidden her from seeing the young man she loves. She loses her ability to sleep, her appetite, and ultimately her ability to speak (the aphonia of the title).

MP's reading is that aphonia "represents a refusal of coexistence, just as a fit of hysteric is, for other patients, a means of fleeing the situation. The patient breaks with the relational life of the familial milieu" (raw line 2603). The patient cannot swallow because "swallowing symbolizes the movement of existence that allows itself to undergo events and assimilate them." She is "literally unable 'to swallow' the prohibition." Aphonia is not a refusal of speech; it is a refusal of the structural togetherness that speech presupposes.

Recovery is correspondingly framed as the body "again open[ing] to others or to the past, when it allows itself to be shot through by coexistence and when it again signifies (in the active sense) beyond itself" (raw line 2632).

This is where the term reaches its full argumentative weight in PhP. The aphonia patient is the case-study negative exhibit that makes coexistence visible by removing it — analogous to how Schneider's negative case exhibits the intentional arc.

Coexistence in sensation, in space, in time

  • In sensation (raw line 3024): "we are defining sensation as coexistence or as communion." The sensing subject "does not posit [qualities] as objects, but sympathizes with them, makes them its own, and finds in them his momentary law." Sensation is coexistence between sensing pole and sensed pole — neither active constitution nor passive reception.
  • In spatial perception (raw line 1403): the order of A, B, C on a contour is "their manner of coexisting before our eyes." Spatial coexistence is not the sum of separate existences.
  • In Husserl's "concordant series" reading (raw line 1880): "if there is to be an absolute object, it must be an infinity of different perspectives condensed into a strict coexistence, and it must be given as if through a single act of vision comprising a thousand gazes." The absolute object is unattainable precisely because such a strict coexistence is unrealizable.
  • In intersubjectivity (raw line 1183): Reflective analysis "is unaware of the problem of others" because it cannot grasp "Myselves coexisting in a world" (raw line 1733) — only "abstract Egos" without coexistence.

Coexistence as broader than Mitsein

PhP's most explicit confrontation of coexistence with Mitsein is in Part Three's discussion of historical materialism (raw lines 2688–2702). Marx's economic relations are one expression of Mitsein; Mitsein in turn is one expression of coexistence. PhP's coexistence reaches lower (sensation, body) and broader (history, sexuality) than Heidegger's Mitsein, which is restricted to Dasein's existential being-with.

This is why coexistence cannot simply be merged into mitsein (if such a page exists) or into intercorporeity. It is the wider structural genus.

Positions

The wiki has not previously thematized this term as a concept. The 2026-04-25 silent-key scan (Phase 2 of the wiki audit) surfaced it. Pre-existing wiki pages mention "coexistence" incidentally — speaking-spoken-speech, co-naissance, making-visible, phenomenal-field — but no page treats it as a stand-alone concept.

Secondary literature on PhP intermittently treats coexistence (e.g., Carman's Foreword to the Landes translation; Beith's Birth of Sense discusses the aphonia chapter), but rarely with the specific structural focus the silent-key scan recommends. The audit's claim — that coexistence is PhP's stand-alone alternative to both Paarung and Mitsein — is novel here, hence epistemic_status: novel.

Connections

  • is the condition of intelligibility of intercorporeity — coexistence is the broader structure of which intercorporeity is the bodily-intersubjective subspecies.
  • is a reformulation of Husserlian Paarung — same problem (how the Other is given non-inferentially) without the analogical apparatus of the Fifth Cartesian Meditation.
  • contrasts with Heideggerian Mitsein — same structural intuition (being-with as not added to being), but PhP's coexistence reaches into sensation and the body's parts, where Mitsein names only Dasein's existential being-with.
  • is the condition of intelligibility of speaking-spoken-speech — speech is "the most tightly linked to communal existence, or, as we will say, to coexistence" (raw line 2603); spoken speech presupposes a prior coexistence.
  • contrasts with Sartrean opposition through the Look — coexistence is given before conflict, not produced by it.
  • enacts the perceptual-faith structure that V&I will later thematize — coexistence is what perceptual faith trusts in.

Coexistence in the political register (1946–47)

The 2022 Inédits I (Mimésis) closes the open question above (whether coexistence persists in MP's later work) by demonstrating that coexistence is load-bearing in the political register of 1946, in continuity with PhP's silent-term usage. Three attestations:

  • As paraphrase of "vie à plusieurs": "C'est problème de la vie à plusieurs" (L'existentialisme et la politique, Inédits I p. 204). Politics is coexistence; the political problem is what arises when coexistence cannot be presupposed.
  • As the conflict-vs-Mit-sein pivot: "C'est le conflit et non le Mit-sein qui définit rapports humains. Conflits des libertés" (Conflits moraux, p. 296). MP makes the same anti-Heideggerian move as in PhP but in political register: the structural togetherness that Mit-sein names anonymously is, when concretized politically, the conflict — and conflict itself presupposes coexistence as its terrain.
  • As what violence transforms: "Il y a Hélène aimant Jean et la situation commune qui en résulte pour eux. Violence transformée en coexistence" (Aspects politiques, p. 214, in MP's reading of Beauvoir's Le Sang des Autres). The 1946 reading of Beauvoir is the only place where MP makes the transformative dimension explicit: violence is not the negation of coexistence but its (provisional, fragile) mode.

These 1946 attestations confirm the silent-key reading of the 2026-04-25 audit and extend it: coexistence is broader than Mitsein not only descriptively (covering sensation, body) but also politically (structuring "vie à plusieurs," authorizing the "incarnation" solution, framing the violence/communauté problem of HT). The aphonia chapter's "refusal of coexistence" turns out to be the same structure that the 1946 Aspects politiques analyzes as the failure of the political problem.

Open Questions

  • Does coexistence persist as a technical term in MP's late (1955–61) work? V&I's primary concepts list intercorporeity, Ineinander, and reversibility but not coexistence — the 1946–47 attestations suggest the term survives into the political register but is then absorbed into late-MP's other vocabulary; whether absorption is preservation or supersession is open.
  • Is there a French-text difference between coexistence, coexister, and communal existence worth tracking? The Landes translation uses "coexistence" consistently; the French original may distinguish more finely.
  • The aphonia chapter is structured around coexistence; how does the recovery mechanism — "shot through by coexistence" (line 2632) — relate to MP's later doctrine of perceptual faith and to Saint Aubert's cristallisation?
