Maurice Merleau-Ponty

French phenomenologist and philosopher (1908-1961). Professor at the Collège de France from 1952 until his sudden death from a heart attack on May 3, 1961 — he was reading Descartes's Dioptrique and preparing notes for his course "Cartesian Ontology and Ontology Today." Author of Phenomenology of Perception (1945), The Visible and the Invisible (unfinished, posthumous 1964 — see merleau-ponty-1968-visible-and-invisible for the source page), and "Eye and Mind" (1961).

Key Points

  • His late philosophy (1959-1961) evolves from phenomenology of perception into a new "indirect ontology" that works through art, the history of philosophy, and the concept of nonphilosophy to approach Being as the ineinander of visible and invisible
  • The constructive heart of the late ontology is Ch 4 of V&I ("The Intertwining—The Chiasm"), where MP introduces flesh, chiasm, reversibility, dehiscence, and the visible/invisible structure
  • Auto-correction of Phenomenology of Perception: a January 1959 working note explicitly disowns the "Tacit Cogito" of his earlier work — "What I call the tacit cogito is impossible. To have the idea of 'thinking'... it is necessary to have words" (V&I working note, January 1959). This is one of the most striking auto-corrections in the entire MP corpus and marks the threshold between his middle and late thought
  • He maintained uniquely productive relationships with both Husserl and Heidegger, finding resources in both while remaining critical of each — the 1959 course contains the most detailed engagement with Heidegger anywhere in his oeuvre
  • He argues that art carries genuine philosophical content — painting is "philosophy entirely in action" (Klee) — and that the crisis of official philosophy (nonphilosophy) is "inessential" because philosophical consciousness is at its highest precisely in this crisis
  • The "barbaric Principle" attestation: a November 1960 working note shows MP himself using Schelling's term ("the indestructible, the barbaric Principle") to describe the flesh of the world — direct primary-text confirmation of the Schelling-Naturphilosophie connection that runs through Knight's and Gardner's readings
  • The 1956–60 Nature courses as the project's pivot: Three successive Collège de France courses on the concept of Nature (1956–57, 1957–58, 1959–60, collected in merleau-ponty-2003-nature) form the textual bridge between the 1954–55 Institution and Passivity courses and the V&I working notes. Course 1 runs a historical-archaeological critique (Descartes, Kant, Schelling, Bergson, Husserl); Course 2 reads theoretical biology (Uexküll, Portmann, Lorenz) as the empirical site for a new concept of Nature; Course 3 (contemporaneous with the V&I working notes) articulates the flesh as Urpräsentierbarkeit des Nichturpräsentierten, the Ineinander of animal and human, and MP's explicit "psychoanalysis of Nature." Nearly every concept of the late ontology — wild Being, flesh, intercorporeity, interanimality, natural symbolism, the visible/invisible — receives its public textual elaboration in these courses before reappearing in the compressed form of the working notes
  • His final position (per V&I Ch 4 closing line): reversibility is "the ultimate truth" — there is no synthesis, no dialectical reversal; what we have are "two aspects of the reversibility"

Details

The PhP Phase (1945)

Phenomenology of Perception is MP's Docteur ès lettres major thesis, published in 1945 with Gallimard. It is the book on which nearly every subsequent MP thesis builds and against which the late ontology (especially the V&I working notes) explicitly defines itself. The book's structure — Introduction on classical prejudices, Part One on the body, Part Two on the perceived world, Part Three on being-for-itself and being-in-the-world — inaugurates a large number of concepts that will recur across MP's career: motor-intentionality ("Consciousness is originarily not an 'I think that,' but rather an 'I can'"), intentional-arc, body-schema (situational, not positional), phenomenal-field, operative-intentionality (fungierende Intentionalität), originary opinion (the 1945 form of what V&I calls perceptual faith), the tacit cogito and the spoken cogito (the doctrine later retracted), speaking speech and spoken speech, conditioned-freedom, and the être au monde preposition ("in and toward the world") that becomes MP's signature locution.

Two things about PhP that are not obvious and matter for its relation to the late work:

  1. PhP already contains the doctrines the late ontology supposedly introduces. perceptual-faith is there as "originary opinion." sedimentation is a technical term throughout. passivity is explicitly titled as a subsection of Part Three Ch II ("Passivity and activity"). institution is not yet a thematic concept but the word appears in Part One Ch VI.h ("paternity is an institution"). Intercorporeity is anticipated in Part Two Ch IV's baby-mouth example. The late ontology is not an innovation but a radicalization of doctrines already at work in PhP.

  2. PhP's rupture with Sartre is already complete in 1945. Part Three Ch III (Freedom) is a sustained demolition of Sartre's Being and Nothingness without ever naming Sartre. The formulation "Our freedom is either total or non-existent. This is the dilemma of objective thought and its accomplice, reflective analysis" is the unnamed Sartrean target. This is ten years before the political break of 1955.

The PhP that the late ontology later retracts is more narrowly circumscribed than often supposed. The explicit retraction concerns the tacit-cogito ("the Cogito I described twenty years ago was merely a silent Cogito, and therefore still a variant of the pensée de penser" — February 1959 working note). Everything else in PhP — the body-centered analyses, the critique of reflection, the doctrine of operative intentionality, the thesis of conditioned freedom — survives into the late ontology in modified form.

The 1953 Course: Perception as Expression

The 1953 Thursday course — MP's inaugural Collège de France course — is the critical bridge between PhP (1945) and the 1954-55 Institution/Passivity courses. MP explicitly critiques PhP as having "remained governed by classical concepts" and sets out to show that perception already presupposes the expressive function. The course's innovations: the concept of écart (divergence) as the diacritical structure of perception (its earliest attestation), the thesis that "consciousness is synonymous with imperception" [211], the radical reworking of the body-schema as a "natural idea" that is not perceived but is the norm against which perception is defined, and a self-critique of PhP's motivation concept [175v]. The course's fundamental thesis: "Movement = expression" — movement is not change of location but "disclosure of being, a result of its internal configuration" [70]. The auto-correction of PhP begins here in 1953, not with the 1959 retraction of the tacit cogito.

Late Philosophy (1959-1961)

The Course Notes document three key moves:

  1. From perception to ontology: The earlier phenomenology of perception gives way to a direct engagement with Being — but an indirect ontology expressed through art, language, and embodiment rather than categorical statements
  2. From Husserl to a new position: Husserl's trajectory is traced to show that phenomenology's logic leads beyond transcendental idealism to the lebenswelt — and then further, to the Ineinander as the fundamental structure of Being
  3. Critical engagement with Heidegger: Three defenses against misreadings (negativism, anthropology, metaphysical resumption), but also an implied critique of "direct ontology" that risks leading into silence — "philosophy is perhaps possible as 'the proper silence'" (line 813), but Merleau-Ponty prefers indirect expression through contact with the world

The 1954–55 Collège de France Courses

The Institution and Passivity courses are the pivotal middle moment of MP's post-Phenomenology-of-Perception trajectory. They come after the two years MP spent preparing the abandoned Prose of the World (whose "Indirect Language" chapter becomes the Signs essay of the same title) and before the 1958-59 and 1959-60 courses on "Philosophy as Interrogation" and "Husserl at the Limits of Phenomenology" that lead directly to V&I.

What happens in 1954–55: MP recognizes that the project of extending the phenomenology of perception through a theory of expression (which he had announced to Gueroult in his Collège candidacy Report) has left him "still dependent on the philosophy of consciousness." The 1954–55 courses are the beginning of the corrective. The twin courses develop institution and passivity as the positive and negative sides of a single ontological move: out of the philosophy of consciousness by showing that the subject is both instituting-instituted and laterally passive.

Notable in these courses: the explicit judgment (passing, but decisive) that Husserl had been "slow to separate himself" from the philosophy of consciousness; the extended engagement with Proust as philosophical evidence for the negative-reality-of-love; the extended engagement with Freud as the perceptual-unconscious; the critique of Sartre as binary-dialectical "madness"; the formulation of the ternary dialectic that V&I will later deploy; and the political conclusion (ultraliberalism) that permanent revolution requires "the self-contesting of power."

Sartre's 1961 Biographical-Philosophical Reading

Sartre's posthumous eulogy "Merleau-Ponty Vivant" — written July 1961, two months after MP's death; published Les Temps Modernes 184–185 (Oct. 1961) and Situations IV (1964); see sartre-1984-merleau-ponty-vivant for the manuscript draft (which preserves a bolder reading than the published version) — is the only major source giving the Sartrean reverse vector on MP's philosophy. Where the wiki's other Sartre-engagements track MP's reading of Sartre (PhP Freedom chapter, Adventures Ch 5, the 1954–55 Passivity course critique, Signs Introduction), Sartre 1961 reads MP. Three claims of biographical-philosophical method are central:

  1. Childhood-as-explanation. Sartre treats MP's prolonged maternal-filial intimacy after weaning as the experiential ground of MP's foundational philosophical concept — envelopment in Sartre's structuring (see jean-paul-sartre § "Sartre's 1961 Reading of Merleau-Ponty"). The methodological assumption is that childhood-disposition explains philosophical-disposition. Sartre's evidential anchor: "Their love kept for a long time the form of a large body leaning over a small one and enveloping it, because understanding existence and life, for Merleau, are entirely conditioned by this cardinal principle: envelopment" (manuscript p. 131). The Mother / Nature-as-Mother link runs from this passage to: "Flesh of my flesh: no one had taken literally and worked so hard to develop this idea of Nature as Mother which is today abstract indeed, but which is also inherited from the oldest religions" (p. 131). Whether the methodology is defensible is unsettled (Sartre offers no argument); the wiki tracks it as a Sartrean reading.

  2. The "two ways of being young" typology. MP's Preface to Signs (pp. 34–35) articulates a typology of philosophical disposition: "certain people are fascinated by their childhood… Sartre was of the second kind." Sartre quotes the passage at length and uses it as a structural heuristic for the entire essay: MP is the child-fascinated thinker (whose mature philosophy is envelopment); Sartre is the cast-out child (whose philosophy is liberty). The typology is MP's own — and Sartre treats MP's typology as the most precise diagnostic of their philosophical relationship, more accurate than later political-rupture narratives.

  3. MP's silent Marxist temptation. Sartre 1961 reports a private, never-publicly-avowed pre-war Marxist temptation by MP, abandoned in solitary disappointment without notification of the communist intellectuals. "I believe that everything began with a tender love, and that he was disappointed. But this adventure must have taken place in silence and the communist intellectuals were not even notified. Everything happened between him and himself. He followed the Marxist route and then, I do not know why, he abandoned it" (p. 150). MP reportedly told Sartre "more than once that no one was qualified to deal with morality 'because the proletariat could no longer be considered the bearer of human values.'" JBSP footnote 52 records that the published Situations IV version supplies the Moscow Trials and Humanisme et terreur as the cause, replacing the manuscript's "I do not know why." If the manuscript's silent-disappointment reading is correct, MP's *Adventures of the Dialectic* (1955) and Humanisme et terreur (1947) are not the first MP-statements on Marxism but the second: they are the public-philosophical registrations of an earlier silent-and-private engagement.

The structurally most consequential Sartre-1961 claim is the 1934 dating of the MP/Sartre divergence (see spontaneity-vs-liberty). The standard reception treats the MP/Sartre break as a 1947–55 political drift; Sartre 1961 dates it to the moment of common phenomenological-discovery: 1934, when both arrived at Husserl's Ideen but received intentionality differently. MP read intentionality as spontaneity (the invasion of consciousness by being and the transcendence of being by instituted meaning); Sartre read it as liberty (consciousness as nothingness ceaselessly pursued by being and always escaping). The political disagreements are downstream symptoms of a structural rupture already in place from 1934.

The "wave" metaphor for self-as-historical-actor is reported by Sartre as MP's self-figuration: "He liked to compare himself to a wave; it is a crest among others, and it is the whole sea drawn up which changes itself into a rim of foam" (p. 149). Structurally MP's mature alternative to Sartrean voluntarism: the self is locally a crest, globally the sea-itself becoming foam. See action-at-a-distance for the typed connection.

  • Subject of chouraqui-2016-order-of-the-earth, which traces his reading of Husserl's earth text as developing an ontology of precession and hyper-dialectic through the problem of the "two Cartesian orders"
  • Subject (with Nietzsche) of chouraqui-2014-ambiguity-and-absolute, which argues MP and Nietzsche converge on the thesis that Being is self-falsification through the phenomenon of truth. The book reads MP's existential reduction as parallel to Nietzsche's incorporation-of-truth, and MP's flesh as the same ontology as Nietzsche's will-to-power (metaphysical vehicle of self-falsification)
  • Subject of chouraqui-2016-circulus-vitiosus-deus, Chouraqui's focused 2016 follow-up on the circulus-vitiosus-deus motif as the figure of MP's "ontology of ontology." Develops MP's two February 1959 working notes ("The Tacit Cogito and the Speaking Subject" and "Genealogy of Logic, History of Being, History of Sense") as the site where MP radicalizes the PP Cogito into an ontological principle and introduces the circulus vitiosus Deus as its formal name. Identifies hyperdialectics and surreflexion as MP's own names for the double-circle structure, and adds a previously-under-noticed philological finding: MP's "Syge, the abyss" is Claudel, not Heidegger
  • Subject of gardner-2016-kant-third-critique-schelling, which argues his project recapitulates the Kant→Schelling development via the Third Critique, with the chiasm paralleling Schelling's Real-Idealismus
  • in deep dialogue with Kant — the Third Critique validates his pre-objectivity and motivates the passage beyond Kantian transcendentalism
  • Subject of saintaubert-2021-etre-et-chair-ii — Saint Aubert is the primary interpreter of MP's late B.N.F. unpublished archives (DESC, NPVI, EM1-3, MSME, NMS, PbPassiv, Notes sur le corps, Natu1-3, etc.). The 5-volume Être et chair project (2004 / 2005 / 2006 / 2013 / 2021 — only the 2020 collaboration and 2021 vol. II are in raw/) reconstructs MP's projet intellectuel across 1933-1961 through the unpublished archive. Saint Aubert advances three depth-preserving theses about late MP: (1) the replacement thesis — MP replaces consciousness with unconscious in the late notes (not just supplements); (2) the volant / Cassirer Schwungrad borrowing — MP silently borrows ~20 occurrences 1951-1961 from Cassirer's PSF III 1929; (3) the Gurwitsch causal claim — Aron Gurwitsch's 1957 Théorie du champ de la conscience drives MP's anti-Husserl turn. The reading is archive-primacy: the published V&I is treated as a provisional shape of a project most fully visible in DESC, Notes sur le corps, EM1-3, NPVI
  • Subject of sartre-1984-merleau-ponty-vivant — Sartre's 1961 manuscript-draft eulogy. The reverse vector to MP's reading of Sartre: Sartre's structuring of MP's philosophy as rooted in childhood-envelopment, dating the MP/Sartre divergence to 1934 (the moment of common phenomenological-discovery, with differential reception of intentionality as spontaneity vs liberty — see spontaneity-vs-liberty). The manuscript preserves a bolder reading than the published Situations IV version (per JBSP footnote 18, the published version drops the structural envelopment-framing). Reports MP's silent pre-war Marxist temptation, the wave / crest / sea self-figuration, and the truth-of-meditation diagnostic. Sartre's partial recantation of B&N's responsibility-doctrine at p. 147 is the closest Sartre comes in 1961 to conceding MP's 1945 conditioned-freedom critique

  • live claim, see claims#sartre-childhood-as-philosophical-genealogy — In the unpublished 1961 manuscript draft of Merleau-Ponty Vivant, Sartre dates the MP/Sartre philosophical divergence to 1934 (their differential reception of Husserlian intentionality) and grounds it in their two childhoods (MP's prolonged maternal-filial envelopment vs Sartre's ENS-modeled rupture-disposition). The 1953 political break is downstream of the philosophical-genealogical divergence. Counterpressure: Sartre asserts childhood-explains-philosophical-disposition without arguing for it; the published Situations IV version softens the strong genealogical framing.

The philosophical rupture with Sartre is already complete in Part Three Ch III (the Freedom chapter) — ten years before the 1955 political break.
