Ambiguïté vs Ambivalence (MP's distinction)

Merleau-Ponty's philosophically technical distinction between two opposed modes of being-in-contradiction. Contrary to the received cliché of MP as "philosopher of ambiguity" in a weak, irenic sense, Saint Aubert's Ch I §§ 2-3 establishes that ambiguïté and ambivalence are NOT synonyms but opposed: ambiguïté is the way OUT OF ambivalence. The distinction organizes MP's entire anti-Sartre polemic and anchors the genesis of the "hyperdialectique".

Key Points

  • Ambivalence = psychorigid monocular alternation between incompossible figures. One is trapped in an endless oscillation between perspectives that cannot be held together, unable to access the third term (fond, profondeur) that would allow their coexistence.

  • Ambiguïté = binocular depth-perception that CONQUERS the psychorigidity of ambivalence by accessing the invisible fond. "L'ambiguïté, telle que Merleau-Ponty la comprend, s'avère ainsi parfaitement étrangère au relativisme mou ou irénique auquel on la réduit parfois" (Saint Aubert 2021, p. 64).

  • Cardinal citation (Saint Aubert's synthesis, p. 64): "L'ambiguïté n'est donc pas l'ambivalence, mais désigne tout au contraire la sortie de l'ambivalence, dans une surrection libératrice du vertige."

  • Sartre exemplifies ambivalence; MP seeks ambiguïté. The distinction organizes MP's reading of Sartre as trapped in a dialectic oscillation (toute/rien, être/néant, dévouement/égoïsme) that cannot access the third term of the "bonne dialectique".

Genealogy of the distinction

Saint Aubert (2021 Ch I) traces a precise genealogy from 1951 onward. The Welsh-edition Sorbonne lectures (1949–52, ingested 2026-05-04) reveal a distinct earlier sense of "ambivalence" in MP's vocabulary that predates the Wahl 1951 exchange — the Politzer-derived sense documented in the supplement below. The Saint Aubert genealogy from 1951 onward:

  1. 12 September 1951 — Jean Wahl's private exchange with MP after the Geneva conference on L'homme et l'adversité: Wahl proposes the distinction "bonne confusion" / "mauvaise confusion" (HoXX p. 353-354/237). MP appropriates immediately.
  2. January 1953 — Éloge de la philosophie (inaugural Collège de France lecture): "Quand il [le philosophe] se borne à subir l'ambiguïté, elle s'appelle équivoque. Chez les plus grands elle devient thème, elle contribue à fonder les certitudes, au lieu de les menacer. Il faudrait donc distinguer une mauvaise et une bonne ambiguïté." (EP p. 14)
  3. 1956 — Cours sur la dialectique (PhiDial): revendication of "bonne ambiguïté" as "dialectique comme ambiguïté", against "équivoque"; first consolidated use of "mauvaise dialectique" (RC56 p. 78).
  4. 1957 — La Nature ou le monde du silence: "mauvaise dialectique" applied to Sartre's être-néant position (NMS 116).
  5. 1958 — Preparation of Nature course: first use of "hyperdialectique" (Saint Aubert's discovery).
  6. Autumn 1958 — Introduction à l'ontologie (EM1): hyperdialectique systematic.
  7. Spring 1959 — Le visible et l'invisible Ch 2 (Interrogation et dialectique): Hegel-Sartre "ambivalence" used 16 times in VI2, 13 in preparation feuillets. Hyperdialectique = seule apte à l'ambiguïté.

The psychological anchor (Frenkel-Brunswik)

Else Frenkel-Brunswik's 1949 study "Intolerance of ambiguity as an emotional and perceptual personality variable" (Journal of Personality vol. 18, p. 108-143) provides MP with the empirical basis for the distinction. Rorschach-inspired work shows that psychorigid subjects avoid ambiguity via rigid dichotomies; the capacity to TOLERATE (or rather, TO INHABIT) ambiguity is a mark of mature perception and of mature relationality.

MP distinguishes:

  • Psychorigidity = ambivalence: monocular alternation, inability to hold contradictory figures together via the third term.
  • Mature perception = ambiguïté: the binocular depth-conquering perception. This is the perceptual paradigm for philosophical maturity.

The Michaux-thétique discovery

Saint Aubert's Ch I § 3a establishes that MP's late-1958 reading of Henri Michaux's essay "Un certain phénomène qu'on appelle musique" (Encyclopédie de la Musique, Fasquelle 1958) gives him the cardinal formula:

  • Michaux (p. 186): "C'est la pensée parlée surtout, plus encore que la vie vécue, qui crée l'ambivalence."
  • MP (EM2 [189]v(2), 1959, with marginal "Bon à relire avril 1960"): "C'est le thétique qui est ambivalent. Mon préobjectif-ambigu est promiscuité sans équivoque."
  • MP (EM2 [227], note intitulée "Ambiguïté, Être, ambivalence"): "L'idée de l'ambiguïté par transcendance, donc. Elle entraîne que toute conscience thétique soit, en tant justement que thétique et univoque, dans l'ambivalence, refoulant hors d'elle-même une contre-signification avec laquelle elle est incompatible."

The thétique (the act of positing a definite predicate) is inherently ambivalent because it is "ventriloque" (Plato, Sophiste 252c, via Dial-T&C 189, cours du 30 janvier 1956): the univocal thesis secretly carries its contradictory with it, forbidding the third term from emerging. Univocity is not the absence of ambivalence; it is the suppression of ambiguïté.

Music for Michaux (MP adopts): "axe d'avant l'ambivalence" — an archaic axis of desire that precedes the thétique and delivers an "extraverted" ambiguïté.

Perceptual paradigm

MP's cardinal perceptual paradigm: BINOCULAR vision conquering depth. Two monocular images that would alternate in ambivalence (figure-ground inversion, bistable figures) are resolved by accessing the third term: the fond, the invisible-as-profondeur, which MP eventually names figuratifs. This paradigm generalizes:

  • Conceptual alternation (Sartre's être/néant) = ambivalence.
  • Conceptual depth (MP's être-chair-comme-commune-transcendance) = ambiguïté.
  • Ethical alternation (dévouement/égoïsme, amour/haine) = ambivalence.
  • Ethical depth (perception d'autrui, naissance, co-naissance) = ambiguïté.
  • Theological alternation (Dieu tout-puissant / néant) = ambivalence.
  • Theological depth (Dieu figuratif, "s'est fait l'ombre de notre ombre", EP p. 49) = ambiguïté.

The hyperdialectique

VI2 p. 129 gives the mature formula: "Ce que nous appelons hyperdialectique est une pensée qui, au contraire, est capable de vérité, parce qu'elle envisage sans restriction la pluralité des rapports et ce qu'on a appelé l'ambiguïté. La mauvaise dialectique est celle qui croit recomposer l'être par une pensée thétique, par un assemblage d'énoncés, par thèse, antithèse et synthèse; la bonne dialectique est celle qui est consciente de ceci que toute thèse est idéalisation, que l'Être n'est pas fait d'idéalisations ou de choses dites, comme le croyait la vieille logique, mais d'ensembles liés."

Hyperdialectique = ambiguïté-at-the-ontological-register, against Sartre's ambivalence.

Positions

  • saintaubert-2021-etre-et-chair-ii (Ch I §§ 2-3) elaborates the full genealogy of the distinction; as Saint Aubert 2021/2023 reference back to Du corps au désir (Saint Aubert 2013, Être et chair I, Vrin — not in raw/), the genealogy is also said to extend to Klein and Frenkel-Brunswik in the 2013 volume's Ch VII. Saint Aubert insists the distinction is NOT self-evident — MP may have partly trapped himself by the term "ambiguïté", which invites the weak reading.
  • Standard commentators (esp. pre-2005) sometimes collapse ambiguity and ambivalence, reading MP as a philosopher of loose indeterminacy. Alphonse de Waelhens' 1951 Une philosophie de l'ambiguïté (the foundational early study) uses the term ambiguïté without the technical distinction MP was already drawing.
  • chouraqui-2014-ambiguity-and-absolute uses "ambiguity" for MP's position in its technical sense; Chouraqui's "good ambiguity" (via his own reading of Nietzsche) is compatible with Saint Aubert's "sortie de l'ambivalence" but not explicitly tied to Frenkel-Brunswik.

Connections

  • anchors good-ambiguity — the mature register of ambiguïté is the conquest of depth against monocular oscillation.
  • contrasts with bad ambiguity — which is in fact more properly named ambivalence; the structural identity bad ambiguity = ambivalence is now treated in the Bad Ambiguity = Ambivalence section of good-ambiguity.
  • generates hyper-dialectic — hyperdialectique = ambiguïté at the ontological register.
  • underpins Sartre-critique across self-falsification, perceptual-faith (ambivalence = the refusal of perceptual faith).
  • is the psychological ancestor of figuratifs — the third term that resolves monocular alternation is a figuratif.
  • depends on ecart — binocular depth operates through the écart between monocular images; ambiguïté is the ontological generalization of écart.
  • relates to Wahl's bonne confusion — the genesis- of-MP's-distinction, via the 1951 private exchange.
  • operates through perceptual-faith — foi is what makes ambiguïté livable; croyance retreats to ambivalence.
  • is an instance of self-falsification — in Chouraqui's vocabulary, ambivalence is a self-falsification that refuses its own structure; ambiguïté is the self-falsification that acknowledges itself.

Open Questions

  • Should bad-ambiguity be renamed to clarify that MP's target is properly ambivalence? Resolved 2026-04-23 (option c): the bad ambiguity = ambivalence identification is now treated as a subsection on good-ambiguity; the slug bad-ambiguity resolves to that page via alias. Saint Aubert's reading ("Merleau-Ponty s'est en partie piégé lui-même", p. 64) is preserved there as the cardinal philological argument.
  • What is the relation between ambiguïté (perceptual depth) and the écart (perceptual diacritique, MSME 1953)? Both operate via the unthematized third term.
  • Can ambiguïté be thought at the political/historical register, not just the perceptual? Les aventures de la dialectique (1955) suggests yes (the politique as hyperdialectique), but Saint Aubert does not develop this. The 2022 Inédits I edition supplies a partial answer for the early MP: the 1947 reading of Gide's strabisme / ambiguïté consciente (a holding-in-tension of art-religion, morality-of-rupture, and political-rupture without synthesis — Gide's "credo du non-credo," Inédits I pp. 277–279) is a 1946–47 articulation of ambiguïté in the cultural-political register. Wahl's Fontaine April 1946 challenge to MP's "en aucun cas" (cited Inédits I p. 189) is what the 1947 Gide-reading responds to: Wahl had asked whether MP's existentialism, like Sartre's, collapsed too easily into moralism; MP's response (extended through the HT preface 1947 and Lecture de Montaigne December 1947) is to thematize Gide's ambiguïté consciente as the ancestor of MP's own bonne ambiguïté (1951, Pa.2). The cultural-political register of ambiguïté is therefore older than the 1955 hyperdialectique; it begins with the Wahl-MP 1946 exchange and the Gide-reading of 1947.
  • See also question page: is-ambiguite-the-sortie-from-ambivalence — whether Saint Aubert's reading of ambiguïté as the sortie from ambivalence is philologically defensible against the Waelhens-1951 reception of MP as "philosopher of ambiguity" in the loose, irenic sense.

The 1949–50 Earlier Layer: Politzer-Derived Ambivalence (CPP ch. 2 §III)

The Welsh-edition Sorbonne lectures document a distinct earlier sense of "ambivalence" in MP's vocabulary, articulated at the 1949–50 Sorbonne — predating the Wahl 1951 trigger by ~18 months. See claims#ambivalence-as-unconscious-replacement-predates-wahl-1951 (live; promoted from candidate at the 2026-05-05 Phase 8 seventh run).

The earlier sense is Politzer-derived, embedded in the broad-vs-narrow psychoanalysis taxonomy:

"We should therefore prefer this notion of ambivalence which paints perfectly all that is equivocal in certain behaviors, 'resistances' to treatment, of which the subject is partially complicit, attitudes of hate that are at the same time love, desires that express themselves as agony." (CPP ch. 2 §III)

In this 1949–50 sense, ambivalence is the positive technical term that broad psychoanalysis substitutes for "the unconscious": the dream is lived "in symbols which are not conventional signs" but "affective realities, full of sense, freely projected" — signification is "ambivalent (lived, predicted, but ignored) and not unconscious." MP credits this directly to Politzer's Critique of the Foundations of Psychology.

The two senses must be tracked separately:

Period Source Sense Function
1949–50 (Sorbonne) Politzer-derived (broad psychoanalysis) positive technical replacement for "the unconscious"; signification that is "lived, predicted, but ignored" substitutes for unconscious; characterises love-as-hate, desire-as-agony
Post-1951 (Wahl-derived) Saint Aubert genealogy pathological monocular alternation, opposed to ambiguïté the bad pole, psychorigidity against which ambiguïté is the sortie

These two senses are not in direct contradiction — the post-1951 ambivalence could be read as a narrower, pathologised register of the 1949–50 ambivalence — but they are clearly different argumentative deployments. The Saint Aubert genealogy traces the post-1951 emergence; the 1949–50 sense is artifact-internally documented in the Welsh edition. Wiki implication: the genealogy on this page now includes the Politzer-derived 1949–50 layer as the earliest documented MP usage of "ambivalence" as a technical philosophical term, prior to the Wahl-1951 inflection toward the pathological-vs-ambiguïté distinction.

The crucial open question is whether, when MP appropriates Wahl's 1951 bonne / mauvaise confusion and reformulates it as ambiguïté / ambivalence, he is reusing his own earlier Politzer-derived term in a new technical role (likely) or adopting a fresh term (less likely, since "ambivalence" was already in his Sorbonne lectures). On the first reading, the Wahl 1951 exchange is the moment of reformulation, not the moment of first use. This refines the Saint Aubert genealogy without contradicting it — Saint Aubert's claim is about the technical distinction (ambiguïté vs. ambivalence) crystallizing post-1951, not about the lexeme "ambivalence" first appearing then.

This is the bridging articulation between Gide-strabisme (1947) and the bonne ambiguïté of 1951 (Pa.2 — MP's letter to Martial Guéroult). The N.D.L.R. also contains MP's earliest published use of "déhiscence" in connection with Hegel: "il faut en regarder en face l'énigme centrale, cette déhiscence qui ouvre à la nature et à l'histoire, mais qui a déjà son analogue à l'intérieur de la nature, et ne s'explique donc pas 'par en bas', mais pas davantage 'par en haut'."
