Tacit Cogito

Merleau-Ponty's name in Phenomenology of Perception for the pre-linguistic self-presence of consciousness that underlies the explicit Cartesian Cogito. Introduced in Part Three Ch I.o–p as the ground of the "spoken cogito" (the cogito one performs by reading Descartes's text), the tacit cogito is the book's attempt to reconstruct a self-presence that is pre-predicative but not foundational. The doctrine is explicitly retracted by MP in the February 1959 working notes of The Visible and the Invisible — "What I call the tacit cogito is impossible… The Cogito I described twenty years ago was merely a silent Cogito, and therefore still a variant of the pensée de penser."

Key Points

  • The 1945 formulation is unstable on its own terms: Even in PhP, MP admits that the tacit cogito "has but a fleeting hold upon itself and upon the world" (p. 466), that it "only knows itself in limit situations in which it is threatened" (fear of death, the other's gaze), and that "the tacit Cogito is only a Cogito when it has expressed itself" (p. 466). This last line is either the doctrine's saving clause or the marker of its self-destruction, depending on how one reads it.
  • Distinction from the spoken cogito: The "spoken cogito" is the cogito performed by reading Descartes's text — "One thinks, one is" (On pense, on est). This is a "second-hand cogito" whose self-evidence is an effect of language. The tacit cogito is what the spoken cogito would have to presuppose if it were to be more than a sentence.
  • Not the Cartesian foundation: The tacit cogito is not self-grounding. MP insists it must be "reconquered, fixed, and made explicit through perceptual exploration and through speech" (p. 466). It is not an Archimedean point; it is a "first perspective" that waits for expression.
  • The hinge of PhP's trajectory: The tacit cogito is where PhP's transcendental ambition both reaches and fails to reach its goal. The problem is precisely that the "silent self-presence" MP wants to describe cannot be described without becoming a "spoken" cogito — at which point it is no longer silent, no longer tacit.
  • The retraction: In two 1959 working notes ("The Tacit Cogito and the Speaking Subject," February 1959), MP writes that the tacit cogito is "impossible," that it is "still a variant of the pensée de penser," and that his entire earlier account must be re-thought through language, the body, and the chiasm. The late ontology of V&I is MP's attempt to do without the tacit cogito — which means it is also the attempt to do without the last Cartesian residue in his own phenomenology.

Details

The Argument in PhP

Part Three Ch I.n–p unfolds a careful argument with a problematic conclusion. The background is Descartes's Second Meditation: I cannot doubt that I am thinking, therefore I am. MP wants to accept that the "I think" is inescapable — but not in the Cartesian interpretation, where it yields a self-transparent, self-grounding ego. MP's alternative interpretation proceeds in two steps.

Step 1: the spoken cogito. When you read Descartes's Second Meditation, the cogito that appears to you is a cogito that has been put into words — "I think, therefore I am." But this is a cogito as a sentence, not a cogito as a self-presence. The reader's "'I' is clearly at issue here, but this is a myself as an idea that is not, strictly speaking, my own, nor Descartes's for that matter; it is the myself of every reflecting man" (p. 462). The cogito you perform by reading is "a second-hand cogito," a "cogito put into words and understood through words." MP calls this the spoken cogito.

Descartes missed the fact that his cogito was spoken. He thought he was giving us the immediate ground of self-presence; in fact he was giving us a text that articulates the cogito — which is a different thing. The true formulation of the Cartesian cogito, read this way, would be: "On pense, on est" — "one thinks, one is." An anonymous, general cogito, not my own.

Step 2: the tacit cogito. But the spoken cogito cannot be all there is. If my reading of Descartes were to do nothing but shuffle the words around, I would not understand the text at all. Something in me must already be in contact with what Descartes is pointing at. MP calls this something the tacit cogito: "Beyond the spoken cogito, the one that is converted into utterances and into essential truth, there is clearly a tacit cogito, an experience of myself by myself" (p. 466). The tacit cogito is what the spoken cogito is the expression of — the pre-linguistic self-presence that makes possible the linguistic cogito's transparency.

But then — and this is where PhP's trajectory becomes unstable — MP starts to hedge. The tacit cogito "has but a fleeting hold upon itself and upon the world." It "does not constitute the world, it catches a glimpse of the world around itself, like a field that it has not given to itself; it does not constitute the word, it speaks in the manner that one sings when one is joyful; nor does it constitute the sense of the word, for this sense springs forth for subjectivity in its commerce with the world and with the others who inhabit it" (p. 466). And finally: "The tacit Cogito, the presence of self to self, being existence itself, is prior to every philosophy, but it only knows itself in limit situations in which it is threatened, such as in the fear of death or in the anxiety caused by another person's gaze upon me."

And most strikingly: "The tacit Cogito is only a Cogito when it has expressed itself" (p. 466).

This last line is the fulcrum. Read one way, it is saying: the tacit cogito is only actualized as a cogito when language takes it up, but it is there as the ground. Read another way, it is saying: there is no cogito without language; the "tacit" cogito is a retrospective projection made from within the spoken cogito. MP in 1945 is writing in the first register. MP in 1959 concludes that the second register is correct and retracts.

The Retraction

The February 1959 working notes to The Visible and the Invisible contain the most explicit auto-correction in MP's corpus. In a note titled "The Tacit Cogito and the Speaking Subject" (February 1959), MP writes:

What I call the tacit cogito is impossible. To have the idea of "thinking" (in the sense of the "thought of seeing and of feeling"), to make the "reduction," to return to immanence and to consciousness of . . . it is necessary to have words. [...] There is no tacit cogito prior to the expression.

And a few pages later:

The Cogito I described twenty years ago was merely a silent Cogito, and therefore still a variant of the pensée de penser.

("pensée de penser" = "thought of thinking" = Descartes's reflexive self-grounding thought.)

The retraction is unusually explicit. MP acknowledges that he had tried to have it both ways — to want a pre-linguistic self-presence but to deny that it is self-grounding — and that the attempt failed. Any pre-linguistic self-presence, once described, becomes a variant of the Cartesian thought-of-thinking. The only way out is to give up the attempt and admit that the "I think" arises in language, not before it.

This retraction is what makes V&I's project make sense. V&I is building a phenomenology that does not depend on a pre-linguistic self-presence. What the tacit cogito was supposed to do — provide a minimal self-relation — is done instead by the flesh, the chiasm, the reversibility. The flesh is self-related not as a thinking-that-thinks-itself but as a "touching touching touched," a perceptual-motor self-relation that has no thetic structure at all.

See chouraqui-2016-circulus-vitiosus-deus for a close reading of these two working notes and their transformation of the PhP cogito into the ontological principle of the late ontology.

Why the Doctrine Mattered in 1945

It is easy in hindsight to read the tacit cogito as a mistake MP grew out of. But the concept was doing important work in 1945. PhP needs something to ground the phenomenological reflection it is practicing — some self-relation that is not yet judgment but is enough for reflection to get a grip. The tacit cogito is MP's attempt to provide this without falling into either the Cartesian apodictic ego (which over-grounds) or the Bergsonian intuition (which provides no grip at all).

The 1945 doctrine is therefore a compromise formation: a self-presence that is thin enough not to be Cartesian and thick enough not to be nothing. The compromise holds for a few pages and then unravels. The instability is the doctrine's own.

The Tacit Cogito and Language

One of the most telling moves in the PhP passage is MP's acknowledgment that language "installs in us" the impression of grasping "a truth separable from that expression." "The wonder of language is that it makes itself be forgotten: my gaze is drawn along the lines on the paper, from the moment that I am struck by what they signify, I no longer see them" (p. 462). Descartes's Meditations work on us precisely because they make us forget that we are reading. But this is exactly the structure MP is diagnosing: Descartes's reader takes a linguistic operation for a pre-linguistic foundation.

The diagnosis is right. But then MP asks: behind the forgetfulness, what is there? And his answer — a tacit cogito — is itself subject to the same diagnosis. If the forgetfulness of language is what makes the spoken cogito appear pre-linguistic, why would the tacit cogito not be another effect of the same forgetfulness? This is the question MP himself poses in 1959.

Positions

  • MP 1945 holds the tacit cogito as a pre-linguistic self-presence that grounds but does not constitute the spoken cogito.
  • MP 1959 rejects the tacit cogito as "impossible" and as "still a variant of the pensée de penser."
  • Descartes takes the cogito as a self-grounding foundation; MP in 1945 tries to reinterpret this as a tacit self-presence, and in 1959 rejects both interpretations.
  • Husserl has an apodictic self-evidence of the transcendental ego; MP 1945 is trying to soften this into a tacit cogito, and 1959 rejects the softening as still too Cartesian.
  • Derrida's Speech and Phenomena (1967) argues against Husserl that the "silent self-presence" of internal monologue is already structured by signs — a position strikingly parallel to MP's own 1959 retraction.
  • Chouraqui reads the two February 1959 working notes as the decisive moment of MP's late ontology, where the PhP cogito is radicalized into the circulus vitiosus Deus of the late ontology.

Saint Aubert's third reading: the cogito charnel as inconscient primordial

Where Chouraqui reads the retraction as radicalising the cogito into an ontological principle (self-falsification), Saint Aubert (E&C II Épilogue § 2a "Le cogito charnel ou l'épreuve de nos attaches") reads it as replaced by the Claudelian question Où suis-je et quelle heure est-il? and carried by the inconscient primordial. The 1945 "je suis à moi en étant au monde" (PhP 466) is preserved — but its subject is no longer "conscience" in any form. The PhP formulation survives; the term "conscience" does not.

The continuity: PhP tacit cogito → 1959 retraction → carnal cogito / Où suis-je et quelle heure est-il? → oui initial of inconscient primordial. Saint Aubert's reading aligns with Chouraqui's (both take the retraction seriously) but specifies the carnal-unconscious register where Chouraqui specifies the self-falsification register. The two readings are complementary.

"Dès la Phénoménologie de la perception, Merleau-Ponty situe ici la véritable épreuve de nous-même, un Cogito charnel étranger aux illusions solitaires de la conscience réflexive comme à celles d'une auto-affection, et congruent à son intention philosophique : penser notre unité personnelle telle qu'éprouvée conjointement à l'exercice de notre être-au-monde." (E&C II Épilogue § 3c)

See inconscient-primordial for the positive filling-in: the oui initial of the carnal unconscious is what remains of the self-relation after the retraction, performed not by a "pensée de penser" but by the chair's consent to being.

Connections

  • is the doctrine that MP retracts in the February 1959 V&I working notes
  • is the 1945 form of what the late ontology will replace with flesh, chiasm, reversibility
  • replaced by inconscient primordial — the oui initial of the chair as MP's ultimate answer to the Cogito
  • survives as the Claudelian cogito — Où suis-je et quelle heure est-il? (13 occurrences in VI preparation); see perceptual-faith
  • is the last Cartesian residue in PhP
  • is the site where philosophy-of-reflection is both critiqued (in how Descartes is read) and re-enacted (in the tacit cogito itself)
  • is the seed of circulus-vitiosus-deus — Chouraqui reads the February 1959 notes as converting the tacit cogito into the ontological principle
  • is adjacent to speaking/spoken speech — the same distinction MP makes for language in Part One Ch VI is the basis for the tacit/spoken cogito distinction
  • contrasts with hyper-reflection — which is the method that survives after the tacit cogito is given up
  • is reinterpreted in Chouraqui's reading as the figure of "ontology of ontology" — the reflexive structure in which being includes its own self-presentation

Open Questions

  • Did MP really have to retract the tacit cogito? The 1945 formulation — "the tacit cogito is only a cogito when it has expressed itself" — is already conceding most of what the 1959 retraction demands. Is the retraction a change of mind or a change of emphasis?
  • Does the retraction of the tacit cogito commit MP to a fully linguistic account of self-presence? Some commentators (Dillon, Barbaras) think not; they read the 1959 notes as eliminating only a particular Cartesian residue while preserving a body-based self-relation.
  • What does the tacit cogito's retraction do to the status of motor-intentionality and the "I can"? The "I can" was supposed to be the operative-intentional alternative to the "I think" — but if the "I think" was always spoken, was the "I can" always enacted? The wiki's default answer is yes: the "I can" is a doing, not a silent self-presence.
  • Can any phenomenology do without some minimal tacit self-presence? Derrida in Speech and Phenomena says no. The late MP says no through a different route — the self-presence survives but as flesh, not as cogito.

The tacit/spoken cogito distinction returns as the vertical cogito / horizontal cogito distinction, now freed from the "silent self-presence" framing that made the PhP tacit cogito "impossible." The cardinal formulations are at new-raw line 2608 ("I exist before knowing that I am") and line 2697 (the cogito "west like the flame, it is virtus nativa, facultas cogitandi, working and opening mind"). The figure is no longer silence (which would still be pensée de penser) but flame (2554, 2560, 2608, 2697) — self-presence as a flame with a foyer it doesn't know, i.e., temporally thick, with its own obscurity inside the light. The "third domain" / aliquid esse formulation at line 2578 names the ontological form: the cogito is "not even a third domain: universe where the other two enter." The Course 2 materials are the explicit working-out of what replaces the retracted tacit cogito; the V&I draft chapter's Ineinander formulations inherit this (Appendix A, 3849-4013).
