Martin Heidegger

German philosopher (1889-1976). In Merleau-Ponty's Course Notes, Heidegger receives "the most rigorous, detailed, and explicit engagement" found anywhere in Merleau-Ponty's oeuvre (Course 1, Part II.B). Merleau-Ponty traces the passage from Being and Time through On the Essence of Truth to the later writings on language, technology, and the history of Being.

Key Points

  • Merleau-Ponty defends Heidegger against three misreadings: (1) negativism (philosophy as anxiety before death); (2) anthropology (Being reduced to human attribute); (3) metaphysical resumption (the Leibnizian "why is there something rather than nothing?")
  • The Kehre (turn) is not a reversal but a deepening: the later philosophy is farther from Being-in-itself than Being and Time because "negativism always includes an afterthought of pure positivism" (line 639)
  • Being (Sein) is not a supreme being but "that which is not nothing"; "being hides itself as being by taking place as beings" (line 639) — concealment is structural, not theological
  • Language is not instrumental but the "house of Being": "the significations are only divergences (écarts) between significations" (line 702). "The origin of language and the origin of human being are the same thing, and both are violence, myth, secret" (line 734).

Details

The Passage from Dasein to Sein

  1. Being and Time: Dasein has a privileged relation to Being — but described somewhat "subjectively"
  2. On the Essence of Truth: Truth as Offenheit (openness) — "freedom, ek-sistent, disclosive Da-sein, possesses the human being." Dasein becomes a movement of Being
  3. Later writings: Dasein is "the locality of the truth of Being" — Being is Gegend (province), Spielraum (clearing), the field in which everything is deployed

Being and Speech

The impossibility of saying Being as a Sache (object) reveals that Being's relation to speech is constitutive. The word is not a sign for a pre-given referent but a "node" simultaneously in the phonetic and semantic order. Being is "on the side of speech," between created and received language.

Critical Distance

Merleau-Ponty's implied critique: Heidegger's tendency toward "direct ontology" risks leading philosophy into silence. As Lefort notes: Merleau-Ponty "is concerned both to defend him against false interpretations and to be firm in criticizing a direct ontology, whose danger would be to lead the philosopher into silence." Yet Merleau-Ponty concedes: "philosophy is perhaps possible as 'das rechte Schweigen' [the proper silence]" (line 813).

Connections

Earth-Sky vs. Aquatic Ontology

Knight argues that Heidegger's late thought operates within a Hesiodic cosmogonic imaginary — the marriage of Earth and Sky generating the horizon of manifestation. His reading of physis kryptesthai philei as "what emerges has the urge to keep itself closed" remains within revealing-concealing. Knight contends that Merleau-Ponty's aquatic-ontology surpasses this: the primordial waters must recede before any horizon can gather. Aquatic withdrawal is not concealment-within-unconcealment but a more radical disappearance into the absolute past (Ch. 4 §§2, 5).

Inkpin's Critique of Ge-stell as Abstract Mediation (2026)

Inkpin (2026) §4 critiques Heidegger's "top-down" historical-philosophical approach as a paradigmatic case of abstract mediation — postulating an abstract structure (Ge-stell / "enframing") as condition of possibility for empirical phenomena it ought to explain. Two specific Heidegger texts are diagnosed:

  • "The Question Concerning Technology" (Heidegger 1954: 25-27): the claim that modern (post-Galilean) science was "antecedently technical in character — as 'Ge-stell'." Inkpin's diagnosis: "the characteristics of 'enframing' (ontological level) are manifested in the same way by each technological device or process (ontic level); they are to flow downwards, so to speak, rather than being inflected by and approximating to empirical phenomena."
  • "The Age of the World-Picture" (Heidegger 1977: 78): the claim that modern physics is exact because its way of being was antecedently exact. Inkpin reads this as the same inversion-of-explanation move.

Inkpin's critique is that abstract mediation "fail[s] to make intelligible how [it] is to bring about its supposed effects." The implication is that Heidegger's Seinsgeschichte, when generalized to all cultural-historical phenomena, treats them as type-instances of an abstract structure rather than as non-identical concrete artefacts. Inkpin's typology (see non-identity-based-sense) provides the structural ground for the critique — abstract mediation is structurally inappropriate for non-identity-based practices.

A subordinate critique appears in Inkpin fn 37: the Merleau-Pontian view of painting "suggests a more plausible view of the world-founding function of artworks than Heidegger's extrapolation of the Greek temple's 'setting up' (Aufstellen) of a world (Heidegger 1977: 27, 29-31) – a view freed from the implied unity of a 'Volk' and the enigmatic transcendence of 'Being'."

Inkpin's reading is additional to the wiki's prior critiques of Heideggerian "direct ontology" (per MP 2022) and the Knight 2024 aquatic-ontology critique. The three critiques pick out different problems: MP's targets direct access to Being; Knight's targets the Earth-Sky cosmogonic imaginary; Inkpin's targets the abstraction of cultural-historical structures from their empirical instances. All three share the diagnostic that Heidegger's late ontology is structurally over-totalizing, but they articulate the over-totalization at different levels.

Chouraqui's Critique of Heidegger on Nietzsche

Chouraqui 2014 rejects Heidegger's reading of Nietzsche as "the metaphysics of absolute subjectivity" (from the Nietzsche lectures and Holzwege). Heidegger charges Nietzsche with failing to ask the question of Being — treating das Seiende im Ganzen (beings-as-a-whole) under the rubric of will to power without reaching das Sein. Chouraqui counters that Heidegger misreads Nietzsche's refusal as inability:

"For Nietzsche, Being is a challenge; it is not always already here. Our response to Heidegger hence takes an unusual form: yes, Nietzsche refuses to do ontology in the Heideggerian sense, but no, it is not because he overlooks the question of Being but because he considers this question to be irrelevant as long as Being is not achieved. It is inauthentic to view inauthenticity from an authentic point of view." (Transition)

Nietzsche, on Chouraqui's reading, proposes Being as way to be: "Being must be represented as represented because only in representation do Being and its way to be coincide." Nietzsche's ontology is self-falsification — Being as the very movement of the falsification through which the phenomenon of truth appears — and this is not an oversight of the question of Being but a principled rejection of the Heideggerian framing that ontology is always-possible because Being is always-already present. See friedrich-nietzsche and will-to-power for the full argument.

Chouraqui's secondary critique: Heidegger places Nietzsche (wrongly) in the same camp as "absolute subjectivity" while placing MP (wrongly, per Deleuze's pairing) in the same camp as direct ontology. Chouraqui argues MP's "indirect ontology" is closer to Nietzsche than to Heidegger precisely on the point of refusing direct access to Being.

Heidegger's Own Reading of Nietzsche (Primary Source)

Heidegger's *Nietzsche I* lectures (1936-1939) are the wiki's primary-source counterweight to the Chouraqui critique. The 1961 Vorwort frames the publication as making visible "the Denkweg I traveled from 1930 to the Brief über den Humanismus (1947)" — the Nietzsche-confrontation is integral to Heidegger's own Kehre.

Central thesis: Vollendung der Metaphysik. Nietzsche is der letzte Metaphysiker des Abendlandes (the last metaphysician of the West) because his thinking completes (vollendet) the Greek determination of Being-as-presence rather than overcoming it. The Vollendung is the unrestricted unfolding of all the long-held essence-powers of beings to what they demand in the whole; it is what gives the metaphysical age its full stature. Nietzsche's Wille zur Macht and ewige Wiederkehr answer the Leitfrage (basic character of beings + Being of beings as a whole) at maximum extremity, but the Grundfrage (truth of Being itself) remains unasked.

Climactic thesis of Part III: Beständigung des Werdens in die Anwesenheit. The essence of will to power is the willed making-stand-fast of becoming into presence. The "highest" will to power commands becoming to remain — willing becoming into the Anwesenheit-form that is the Greek determination of Being. This is the operative ground of the Vollendung-thesis.

Metaphysical Grundstellung of Nietzsche. The four-fold structure: (a) basic character of beings = will to power; (b) Being of beings as a whole = eternal recurrence; (c) truth-character = *Gerechtigkeit*; (d) ground of human Dasein = the Übermensch. Each component is the most extreme answer along its axis; their conjoint extremity is what makes Nietzsche's Grundstellung the last.

The Vermenschlichung (humanization) thesis. Nietzsche's Vermenschlichung of beings (WP 614: "die Welt 'vermenschlichen'") is the metaphysical completion of Cartesian-modern subjektivität. The Leib (body) becomes the leading thread of world-interpretation; the animal rationale completes itself as the Übermensch — and this completion is the Cartesian subiectum in its most extreme form. This thesis is structurally continuous with Heidegger's later Gestell-analysis (1953-54): the willed Beständigung of becoming = the modern standing-reserve of beings = the Gestell.

The closing horizon: Seinsverlassenheit and the anderer Anfang. The Vollendung is also the Ende of metaphysics — but the Ende opens the Not (need) for the anderer Anfang. The withdrawal of Being (Seinsverlassenheit) experienced as the overshadowing of Sein by Seiendes is itself a movement of Sein, not human oversight: "Die Überschattung des Seins durch das Seiende kommt aus dem Sein selbst, als die Seinsverlassenheit des Seienden im Sinne der Verweigerung der Wahrheit des Seins." The closing Hölderlin verse ("In heiligem Schatten aber, am grünen Abhang wohnet der Hirt und schauet die Gipfel") names this threshold.

Method: Auseinandersetzung. Heidegger's mode of relation to Nietzsche is Auseinandersetzung — "echte Kritik" that follows the wirkende Kraft of a thinker's thought rather than chasing weaknesses. The Sache (matter at issue) is itself constituted in the confrontation. This is not Nietzsche-exegesis but Heidegger's own thinking standing within the Streitfall with Nietzsche.

Targets of polemic. Heidegger explicitly contests Baeumler 1931 (recurrence "ohne Belang"; political reading of will-to-power) and Jaspers 1936 (no conceptual truth in philosophy). Both readings are dismantled in Nietzsche I I.4.

The 1964 Self-Correction (Aletheia ≠ Wahrheit)

"Das Ende der Philosophie und die Aufgabe des Denkens" (1964) — Heidegger's contribution to the UNESCO Paris colloquium "Kierkegaard vivant," published in Zur Sache des Denkens (1969) and reprinted in GA 14 (2007) with marginalia from his Handexemplar — is the public stage of Heidegger's most important late self-correction. The footnote at GA 14 p. 87 cites his own Sein und Zeit (1927) p. 219 by direct page reference and characterizes that translation (ἀλήθεια → Wahrheit) as a Wegirren — a temporary straying — from a decisive insight:

"Wie der Versuch, eine Sache zu denken, zeitweise wegirren kann von dem, was ein entscheidender Einblick schon gezeigt hat, wird durch eine Stelle aus »Sein und Zeit« (1927) S. 219 belegt: »Die Übersetzung (des Wortes ἀλήθεια) durch das Wort ›Wahrheit‹ und erst recht die theoretischen Begriffsbestimmungen dieses Ausdrucks (Wahrheit) verdecken den Sinn dessen, was die Griechen als vorphilosophisches Verständnis dem terminologischen Gebrauch von ἀλήθεια ›selbstverständlich‹ zugrunde legten«. [GA Bd. 2, S. 291]"

The retraction has three layers (see aletheia §"The 1964 Self-Correction" for full treatment):

  1. Aletheia is not Wahrheit — Aletheia grants the possibility of Wahrheit. Truth (in any traditional sense — Übereinstimmung, Gewißheit) belongs to the grounded register; Aletheia-as-Lichtung belongs to the grounding register.
  2. The Wesenswandel-der-Wahrheit thesis is "nicht haltbar". Heidegger's earlier doctrine — that there was an essential change in truth from Greek Unverborgenheit to Roman adaequatio — is rejected. Aletheia als solche was never thought as such by philosophy; what it grants (correctness) was experienced sogleich (immediately) and only as ὀρθότης.
  3. Lethe (Verbergung) belongs to A-letheia als das Herz — not as addition or shadow-to-light, but constitutively. The Lichtung is Lichtung der sich verbergenden Anwesenheit, Lichtung des sich verbergenden Bergens (GA 14 p. 88).

The 1964 essay also enacts the title-substitution announced in its introductory paragraph: the SuZ-task is renamed Lichtung und Anwesenheit. Marginal (27) at GA 14 p. 87 reframes the SuZ-Seinsfrage as "der verkürzte Titel für die Frage nach der Herkunft der ontologischen Differenz." See lichtung, task-of-thinking, and ontological-difference for the cross-page implications.

The wider consequence: every wiki page mentioning Heidegger's "doctrine of truth as unconcealment" should now distinguish (a) the SuZ-1927 register and (b) the 1964 retraction. Pages updated in the 2026-05-01 ingest (per unthought, ontological-difference, seinsgeschichte, auseinandersetzung, vollendung-der-metaphysik, machenschaft, plus this entity page) carry the distinction; pages predating the 2026-05-01 ingest may need targeted Phase 8 review.

The 1964 Cybernetic-Vollendung Specification

The same 1964 essay extends the Vollendung-thesis from the Nietzsche I register (Nietzsche-as-letzter-Metaphysiker, 1936-39) to the late-Heidegger present-age diagnostic: philosophy ends not only in Nietzsche's metaphysical Umkehrung but also in the dispersal of philosophy into the independent sciences and in Kybernetik as the new Grundwissenschaft of the *Weltzivilisation*. Machenschaft (NII V/IX, 1939-46) → Ge-stell (Frage nach der Technik, 1953) → Kybernetik (1964) are three names for the same matter at three publication moments. See machenschaft §"The 1964 Cybernetic Specification."

Open Questions

  • How does Merleau-Ponty's reading compare to Derrida's or Levinas's?
  • Would the critique of "direct ontology" apply to Heidegger's later Ereignis?
  • Is Chouraqui's claim that Nietzsche refuses rather than fails to ask the question of Being sustainable — or does it rest on reading MP's sophistication back into Nietzsche?
  • Does the 1964 retraction of Aletheia-as-Wahrheit require revising the wiki's earlier Heidegger pages that predate the 2026-05-01 ingest? Targeted Phase 8 review may be warranted.

Synthetic Claims

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

  • supported claim, see claims#mp-heidegger-reception-archivally-thin — MP's reading of Heidegger was archivally thin: the Sein und Zeit underlining is limited to §§1–14 and §§25–27 with no annotations; Identität und Differenz notes are bare paraphrases; the 1959 Heidegger course is "transparent / neutral"; 80% of MP's Heidegger references are concentrated in 1958–61; MP began serious Heidegger work only in summer–autumn 1958, by which time MP's ontology was already mature. Promoted to supported 2026-05-05 under R8 user pre-authorization (Phase 8 ninth run). The claim re-positions MP's Seinsdenken register as stylistic-figural emulation rather than philosophical inheritance; the late MP's positive genealogy runs from Brunschvicg-Biran-Blondel-Schilder-Piaget-Marcel-Bachelard rather than from Heidegger. Coheres with claims#circulus-vitiosus-deus-mp-ontology-of-ontology (supported, 2026-05-04): MP-Nietzsche-via-BGE 56 is coordinate-distinct from Heidegger's reading of BGE 56.
  • live claim, see claims#vie-du-lien-prior-to-being-toward-death — MP's Ineinander ontology refuses the Heideggerian être-pour-la-mort and the angoisse-revealed Dasein. The "principe des principes" formulation explicitly inverts Heideggerian priority: the possibility of rupture (freedom, death, body accidents) does not prove anything about the possibility of Ineinander and connection. MP frames la chair as constituted by the vie du lien, intercorporéité, accouplement, prégnance — figures absent from Heidegger's analytic. Per Saint Aubert 2006 Ch V §3.
  • live claim, see claims#erde-to-copernican-necessary-hypostatization — Chouraqui (Order of the Earth, 2016) holds MP's Erde → Copernican Earth movement as necessary hypostatization — read against Heidegger's Spiegel-interview reaction ("photographs of the earth from the moon" as "uprooting") which treats the cosmological Earth as a rupture. Where Heidegger sees breaking, MP sees the essential movement of being. Counterpressure: the framing risks an MP-vs-Heidegger contrast that the existing supported claims#mp-heidegger-reception-archivally-thin complicates.
