Summary
Maurice Merleau-Ponty (1908–1961) was a French philosopher whose work on embodiment, perception, and the body’s relationship to the world made him the most important philosophical ancestor of phenomenological medicine. His 1945 Phenomenology of Perception argued that the body is not an object in the world but the subject through which we have a world at all. His unfinished final work, The Visible and the Invisible, pushed further toward an ontology of flesh (la chair) — the idea that perceiver and perceived are not separate entities bridged by consciousness but two sides of a single reversible tissue of Being. No philosopher has done more to dissolve the mind-body dualism that structures biomedical thinking, and his concepts of the lived body, motor intentionality, and the body schema became standard equipment for everyone from clinical phenomenologists to medical anthropologists.
The Lived Body and Motor Intentionality
In Phenomenology of Perception, Merleau-Ponty reinterpreted the phenomenological distinction between Korper and Leib in spatial rather than temporal terms. Where Husserl and Heidegger had emphasized the temporal structures of experience, Merleau-Ponty understood the lived body as a practical motor engagement with the world — not a theoretical object but a way of inhabiting space. As Aho and Aho summarize it, Merleau-Ponty recognized that “to be a body is to be tied to a world” (James Aho, Kevin Aho, 2009).
This was not merely an addendum to Husserl’s program. It was a fundamental reorientation. For Merleau-Ponty, the body does not merely carry consciousness around; it is the locus of meaning. Perception is not the passive reception of sensory data but an active bodily engagement with the world. We do not first perceive objects and then move toward them; our bodily orientation toward the world is already perceptual. The hand reaching for a glass does not first represent the glass to itself and then execute a reaching movement; the reaching is the perceiving.
From Phenomenology of Perception to a New Ontology
Phenomenology of Perception was Merleau-Ponty’s major achievement, but he was unsatisfied with it. His working notes, drafted in the late 1950s, record an explicit self-criticism: the book’s concept of a “tacit cogito” — a pre-linguistic self-awareness underlying all experience — was, he concluded, impossible as formulated. To have the idea of thinking, to effect a reduction of experience to its core, requires words; there is no pure flux of self-given experiences beneath language (Merleau-Ponty, Maurice, 1968). The earlier work remained trapped, he believed, inside a philosophy of consciousness even while trying to surpass it.
The intended remedy was The Visible and the Invisible (Merleau-Ponty, Maurice, 1968). It aimed to take up again the early analyses of the thing, the body, and the relation between the seer and the visible, and to show that they acquire their full meaning only when enveloped in a new ontology that overcomes the standpoint of consciousness entirely (Merleau-Ponty, Maurice, 1968).
Before March 1959, the project bore the working titles “Being and Meaning,” “Genealogy of the True,” and “The Origin of Truth” (Merleau-Ponty, Maurice, 1968). A May 1960 outline showed planned chapters titled “The flesh of the present or the ‘there is,’” “The plot (trace) of time, the movement of ontogenesis,” and “The body, the natural light, and…” (Merleau-Ponty, Maurice, 1968). This outline reflects the introduction of concepts such as flesh, chiasm, wild being, and the intertwining of the visible and the invisible (Merleau-Ponty, Maurice, 1968).
The Visible and the Invisible
The book opens with what Merleau-Ponty calls “the perceptual faith” — the conviction, common to ordinary people and philosophers alike, that we see things themselves. This faith is paradoxical: it is irresistibly lived but cannot be articulated into theses without contradiction (Merleau-Ponty, Maurice, 1968).
The problem with the philosophy of reflection — the tradition running from Descartes through Kant — is that it attempts to overcome this contradiction by suspending the perceptual faith and reconstructing it from the standpoint of a subject. The operation seems legitimate, Merleau-Ponty acknowledges, but it transforms the perceptual faith from something we live into a belief among others, founded on reasons. It reverses the true order: it is first because we believe in the world that we can believe in the order of our thoughts (Merleau-Ponty, Maurice, 1968). Even the most sophisticated form of reflection, which purports to make consciousness transparent to itself, does not escape what Merleau-Ponty calls “the reflective vice”: it transforms the openness upon the world into an assent of self with self, converting participation into observation (Merleau-Ponty, Maurice, 1968).
What is needed is a different method. Merleau-Ponty proposed three: hyper-reflection (which takes itself and the changes it introduces into the spectacle into account), hyper-dialectic (which holds tensions open rather than resolving them into synthesis), and a kind of intuition understood not as intellectual apprehension but as auscultation or palpation in depth (Merleau-Ponty, Maurice, 1968). The medical metaphor is deliberate: to grasp the lived world, you attend to it as a physician attends to a body — laterally, through contact, not from above.
The body, Merleau-Ponty argues in the opening chapter, is the locus from which all perception arises, and this situatedness is not an obstacle to reaching the world but is constitutive of our access to it (Merleau-Ponty, Maurice, 1968). My vision is always a vision from a certain point of the world. This is not a limitation; the body’s partial, situated engagement is what makes things available as visible at all. The world before science and reflection is neither purely objective nor purely subjective; the subject-object distinction is itself a construction that must be traced back to the lived world (Merleau-Ponty, Maurice, 1968).
The near-coincidence of touch upon touch — the left hand touching the right hand touching — reveals the body’s self-perception as always incomplete. When one tries to catch oneself in the act of perceiving, the coincidence eclipses (Merleau-Ponty, Maurice, 1968). This incompleteness is not a deficiency; it is the very structure of embodied existence.
The Flesh and the Chiasm
The central concept of The Visible and the Invisible is flesh (la chair). The flesh is not matter, mind, or substance. It is “an element of Being” — in the premodern sense of element: a general thing midway between the spatio-temporal individual and the idea, “a sort of incarnate principle that brings a style of being wherever there is a fragment of being” (Merleau-Ponty, Maurice, 1968). Merleau-Ponty is reaching for something that standard Western philosophy has no ready word for. The “elements” — water, air, earth, fire — were not ordinary material objects; they were the media through which things existed. Flesh, for Merleau-Ponty, is the medium through which perceiver and perceived exist in relation to each other.
The seer and the visible are intertwined through the flesh: “He who sees cannot possess the visible unless he is possessed by it, unless he is of it” (Merleau-Ponty, Maurice, 1968). The thickness of flesh between the seer and the thing is not an obstacle but their means of communication; it is constitutive both of the thing’s visibility and of the seer’s corporeity (Merleau-Ponty, Maurice, 1968). This is the operative core of the argument: the body is not a container for a perceiving mind that then reaches out to an external world. The body and the world are made of the same stuff, and that stuff — flesh — is what makes the encounter of seer and seen possible.
Reversibility is always imminent but never fully realized: the coincidence eclipses at the moment of realization, constituting the hinge between touching and touched, seeing and seen (Merleau-Ponty, Maurice, 1968). There is a fundamental narcissism in all vision: since the seer is caught up in what he sees, it is still himself he sees; the vision he exercises he also undergoes from things, feeling himself looked at by the world (Merleau-Ponty, Maurice, 1968).
The chiasm is not merely a relation between one body and the world. Because my body can touch itself touching, the reversibility of touch can extend beyond my own body to other bodies; the perceptual fields of different organisms interweave in what Merleau-Ponty calls intercorporeity (Merleau-Ponty, Maurice, 1968). This intercorporeity is not grounded in a shared consciousness but in the fact that sensibility is the return of the visible upon itself — a carnal adherence of the sentient to the sensed.
In the working notes, Merleau-Ponty extends this further. Fact and essence can no longer be distinguished as separate orders, because Being no longer stands before the perceiver but surrounds and traverses him; the spatio-temporal individuals are already mounted on the axes and dimensions of the body, and ideas are already encrusted in its joints (Merleau-Ponty, Maurice, 1968). The seer does not first encounter the visible world and then form ideas about it; ideas themselves are only accessible through carnal experience. The essence is an invariant revealed by variation, borne on the fabric of experience and the flesh of time (Merleau-Ponty, Maurice, 1968). The seer is the sensible itself coming to itself by a coiling up: what gives perception its weight and thickness is the fact that he who grasps the sensible feels himself emerge from it as homogeneous with it (Merleau-Ponty, Maurice, 1968).
The Working Notes and Late Development
The working notes of The Visible and the Invisible cover the period from 1958 to 1961, the last three years of Merleau-Ponty’s life. Edited and published posthumously by Claude Lefort, they document a philosopher in mid-revision, working out positions that the main text had not yet assimilated. They are philosophically dense and sometimes deliberately fragmentary, but they document the full scope of the late project.
The notes develop the concept of “wild” or “brute” being — the perceptual world before science and reflection, which Merleau-Ponty identifies with Being in Heidegger’s sense: more than all painting or speech, it contains everything that will ever be said, yet leaves us to create it (Merleau-Ponty, Maurice, 1968). He describes the method required to approach this world as irreducibly indirect, like negative theology, which approaches God through what God is not. A direct ontology is impossible; the incompleteness of each reduction is not an obstacle to the method but is the method, “the rediscovery of vertical being” (Merleau-Ponty, Maurice, 1968). The philosopher must stand at the chiasm, the point where the passage from the self into the world and into others is effected, refusing both a world with one sole entry (the solipsism of consciousness) and a world accessible from above (Merleau-Ponty, Maurice, 1968).
The notes also contain Merleau-Ponty’s most explicit self-criticism: the earlier Phenomenology of Perception, he writes, posited a “tacit cogito” (a silent self-awareness beneath language) that is, on his later view, impossible as formulated. Thought requires words; there is no absolute flux of singular experiences (Merleau-Ponty, Maurice, 1968). What remains from the wreckage of the tacit cogito is not silence as pure positivity but a world of non-language significations (fields and a field of fields, with a style and typicality) that language realizes by breaking, and that silence continues to envelop (Merleau-Ponty, Maurice, 1968).
Significance for Medicine
Merleau-Ponty’s philosophy became foundational for the phenomenological approach to medicine. Svenaeus identifies the key phenomenological claim about embodiment as the recognition that everyone not only has a body but is a body — the lived body is the zero-point of all experience, withdrawing silently into the background to allow the world to show up as meaningful (Svenaeus, 2018). This is pure Merleau-Ponty. The silent, transparent body that illness breaks open is the body he described in Phenomenology of Perception; the “flesh” that connects perceiver and perceived in The Visible and the Invisible grounds the therapeutic encounter’s claim to intersubjective understanding.
The concept of intercorporeity follows from reversibility: because the body can touch itself touching, the principle of synergy can extend beyond one’s own body to other bodies, making an anonymous visibility inhabit all seers (Merleau-Ponty, Maurice, 1968). The handshake too is reversible, where one feels touched while touching, and there is no reason why synergy should not exist among different organisms if it is possible within each (Merleau-Ponty, Maurice, 1968).
