Summary

Maurice Merleau-Ponty's 1959 working notes demonstrate that the invisible is not the opposite of the visible, but its latent lining and depth, revealing an ontology of encroachment where subject, sensible world, and alterity intertwine through brute being rather than dualistic or onto-theological categories.

By dismantling classical subject-object divides and transcendental onto-theology, this framework replaces Cartesian dualism and Sartrean negation with an embodied ontology of flesh, depth, and field dimensionality.

0:00-2:00

The Chiasm of Visible and Invisible and the Critique of Sartre

watch

The reading begins with notes from November 1959 exploring how meaning and invisibility dwell within visibility as its virtual focus and inner membrane. Merleau-Ponty contrasts this relationality with Martin Heidegger's comparisons, emphasizing that the visible is pregnant with the invisible. He directly rejects Jean-Paul Sartre's formulation that 'the other's visible is my invisible,' arguing instead that distinct perspectives encroach upon one another within a unified sensible world. Monocular visions and distinct bodily organs unite through this distance-spanning junction to form a single perceptual reality.

  • The invisible is the virtual focus and filigree inscribed inside the visible, not its ontological opposite.
  • Sartre's oppositional view of alterity is replaced by a theory of sensory encroachment where distinct viewpoints access a shared sensible world.
  • Monocular sensory inputs integrate into a vertical, singular existence through a junction operating at a distance.

Articulates the core thesis regarding the visible-invisible relationship and Merleau-Ponty's departure from Sartrean phenomenology.

2:00-6:00

Sensoriality, Total Parts, and Musical Dimensionality

watch

Merleau-Ponty examines the dimensionality of the senses, noting how distinct sensory modalities form an open, unified sensorality. Taking the color yellow as a prime example, he explains how an isolated color can transcend itself when it becomes the illuminating tone of an entire visual field, taking on an ontological function. The sensible represents the whole not through static signification, but because each part violently encroaches upon and transgresses the frontiers of the whole. He compares this dynamic to musical composition, where a single note defines the key of a piece, transforming a localized fact into a universal category.

  • Sensory qualities like color transition from isolated particulars into ontological dimensions and universal levels.
  • The sensible functions through encroachment (Übergreifen), where parts tear away from and overlap the broader whole.
  • Musical keys and atonal composition mirror an ontology of indivision, presenting the universal beneath rather than above experience.

Provides the essential aesthetic and perceptual metaphors (color illumination and musical tonality) central to late Merleau-Pontyan ontology.

6:00-10:00

Ontology of Depth and the Resistance of Flesh

watch

This section investigates the sensible hollowed out in being and establishes depth as the preeminent dimension of the hidden and the simultaneous. Depth prevents the universe from collapsing into flat, juxtaposed views, allowing objects to coexist in varying degrees of proximity and possess an opposing flesh. Citing Wolfgang Metzger's psychological findings on binocular vision, Merleau-Ponty demonstrates that depth is not synthesized by an intellectual intentional act. Rather, depth is an originary field property that automatically resolves non-superposable, out-of-phase sensory profiles into a coherent dimensional presence.

  • Depth is the foundational dimension of simultaneity that enables distinct objects to coexist while hidden from immediate gaze.
  • The 'flesh' of the world acts as an obstacle and resistance to pure visual inspection, confirming its brute reality.
  • Depth is an originary field property rather than an intellectual synthesis constructed by intentional acts.

Explains how the phenomenological concept of 'flesh' and depth grounds realism without reverting to naïve empiricism.

10:00-14:00

The Passivity of Thought and Non-Metaphorical Locality

watch

Merleau-Ponty discusses the 'passivity of our activity,' referencing Paul Valéry's concept of the body of the spirit to argue that our mental initiatives emerge from an open temporal field rather than autonomous subjective will. Transitioning from the philosophy of lived experience (Erlebnis) to originary institution (Urstiftung), he argues that the relationship between the visible and invisible is strictly literal, not metaphorical. The mind does not reside in a spatiotemporal geometric point, but maintains a quasi-locality through an elastic tie and investment in worldly landscapes.

  • Thinking is an involuntary field property connected to temporal streaming rather than a deliberate production of the soul.
  • Phenomenology must move from subjective lived experience (Erlebnis) to originary founding/institution (Urstiftung).
  • The relationship between thought and visibility is non-metaphorical because mind operates through elastic situational investment rather than geometric location.

Crucial for understanding Merleau-Ponty's late critique of subjective idealism and his spatialization of the mind.

14:00-16:00

Ontological Monadology: Rereading Leibnizian Expression

watch

In notes from December 1959, Merleau-Ponty reassesses Gottfried Wilhelm Leibniz's monadology by stripping it of its theological and substantialist commitments. Replacing the sovereign creator God and pre-established harmony with the concept of 'being-in-the-world,' he retains Leibniz's insight that individual perspectives express the entire universe without needing external windows. By rejecting the classical notion of the 'in-itself' and re-anchoring expression in brute perceptual reality, he redefines history and the world as vertical phenomena directly lived in perception.

  • Leibniz's monadological expression is salvaged by replacing God and pre-established harmony with brute being-in-the-world.
  • The famous aphorism that 'the soul has no windows' denotes direct worldly embeddedness rather than solipsistic closure.
  • Rejecting the 'in-itself' transforms expression into a vertical, perceptual engagement with reality.

Synthesizes Merleau-Ponty's ultimate ontological project through a critical phenomenological recovery of Leibniz.

Key points

  • The Invisible as the Filigree and Membrane of the Visible — The invisible is not an abstract metaphysical beyond or a Sartrean negation, but the secret virtual focus and internal dimension inherent within the visible sensible world. Attempting to isolate the invisible makes it disappear, because it exists as the latent structure that gives visibility its coherence.
  • Sensory Encroachment and Dimensional Universality — Particular sensory qualities, such as the color yellow, operate as dimensional totalities: when yellow becomes the dominant light of a scene, it ceases to be an isolated object and becomes a universal ontological key. Like a musical tonic or atonal music, particular sensory facts transform into overarching structural categories of experience.
  • Depth as the Dimension of Coexistence and Resistance — Depth is not an intentional calculation or a geometric line in space, but the foundational field condition that allows distinct objects to coexist simultaneously without collapsing into a flat plane. Depth gives objects their 'flesh' and tangible resistance, emerging from the integration of out-of-phase sensory profiles.
  • The Passivity of Activity and Originary Institution (Urstiftung) — Thinking is not a deliberate creation of discrete concepts by an autonomous sovereign subject, but an ongoing passive condition of being situated within an open temporal field. Thought occurs through us much like a heartbeat or the retention of time, shifting philosophical inquiry from lived experience (Erlebnis) to originary institution (Urstiftung).
  • Reinterpreting Leibnizian Monadology into Brute Being — Leibniz's insight that each monad expresses the whole universe from an irreducibly unique perspective is retained, but stripped of its onto-theological scaffolding like God, pre-established harmony, and substantial in-itselfness. The claim that 'the soul has no windows' simply names our radical, unmediated immanence within the sensible world.
Meaning is invisible, but the invisible is not the contradictory of the visible. The visible itself has an invisible inner framework membrane and the invisible is the secret counterpart of the visible appears only within it. Maurice Merleau-Ponty (narrated)
We have to say being is this strange encroachment by reason of which my visible although it is not superposable on that of the other nevertheless opens upon it that both open upon the same sensible world. Maurice Merleau-Ponty (narrated)

In November 1959,

0:03

Merlaponti was working on what would

0:05

become the unfinished final book, The

0:09

Visible and the Invisible.

0:11

Only 100 years after the birth of Henri

0:14

Bergong and less than 2 years before

0:17

[music] his own death. One note reads,

0:20

"Meaning is invisible, but the invisible

0:23

is not the contradictory of the visible.

0:26

The visible itself has an invisible

0:29

inner framework membrane

0:33

and the invisible

0:36

is the secret counterpart of the visible

0:39

appears only within it. It is present

0:45

unpresentable.

0:48

It's presented to me as such within the

0:51

world. One cannot see it there. And

0:54

every effort to see it there makes it

0:57

disappear. But it is in the line of the

1:01

visible. It is its virtual focus. It is

1:06

inscribed within it in filigree.

1:10

The comparisons between the invisible

1:13

and the visible, the domain, [music] the

1:16

direction of thought are not comparisons

1:19

as in Haidiger. They mean that the

1:22

visible is pregnant with the invisible.

1:25

That to comprehend fully the visible

1:27

relations house, one must go into the

1:31

relations of the visible with [music]

1:33

the invisible.

1:35

The others visible is my invisible.

1:38

My visible is the other's invisible.

1:41

This formula that of Sartra is not to be

1:44

retained. We have to say being is this

1:48

strange encroachment

1:50

by reason of which my visible although

1:54

it is not superposable on that of the

1:57

other nevertheless opens upon it that

2:01

both open upon the same sensible world.

2:04

And it is the same encroachment, the

2:08

same junction at a distance that makes

2:12

the messages from my organs, the

2:15

moninocular images resemble reassemble

2:18

themselves into one soul vertical

2:21

existence and one soul world.

2:25

In another note from November, he

2:28

writes,

2:30

"The senses dimensionality being each

2:34

sense is a world that is absolutely

2:38

incommunicable for other senses and yet

2:42

constituting a something which through

2:45

its structure is from the first open

2:49

upon the world of the other senses and

2:51

with them forms one soul being

2:55

sensorality.

2:57

For example, a color yellow, it

3:00

surpasses itself of itself. As soon as

3:03

it becomes the color of the

3:05

illumination, the dominant color of the

3:08

field, it ceases to be such or such a

3:11

color. It has therefore of itself an

3:14

onlogical function. It becomes apt to

3:17

represent all things.

3:19

With one's soul movement, it imposes

3:22

itself as particular and ceases to be

3:25

visible as particular.

3:29

The world is this whole where each part

3:34

when one takes it for itself suddenly

3:37

opens unlimited dimensions becomes a

3:40

total part.

3:42

Now this particularity of the color of

3:45

the yellow and this universality are not

3:48

contradictions are together sensorality

3:52

itself. It is by the same virtue that

3:56

the color the yellow at the same time

3:59

gives itself as a certain being and as a

4:02

dimension the expression of every

4:05

possible being. What is proper to the

4:08

sensible as to language is to be

4:11

representative of the whole, not by

4:14

signification relation or by the

4:17

imminence of the parts in one another

4:19

and in the whole, but because each part

4:22

is torn up from the whole, comes with

4:25

its roots, encroaches upon the whole,

4:28

transgresses the frontiers of the

4:31

others. It is thus that the parts

4:34

overlap, transparency,

4:38

that the present does not stop at the

4:41

limits of the visible

4:43

behind my back.

4:46

Perception opens the world to me as the

4:49

surgeon opens a body catching sight

4:52

through the window he has conrived of

4:55

the organs in full functioning

4:58

taken in their activity seen sideways.

5:03

It is thus that the sensible initiates

5:07

me to the world as language to the

5:10

other. by encroachment. Uberen

5:15

exceeds transcends.

5:17

Perception is not first a perception of

5:20

things but a perception of elements,

5:23

water, air, of rays, of the world, of

5:26

things which are dimensions, which are

5:28

worlds. I slip on these elements and

5:31

here I am in the world. I slip from the

5:34

subjective to being the alleged

5:37

contradiction between the yellow as

5:40

something and the yellow as the [music]

5:42

title of a world. This is not a

5:45

contradiction for it is precisely within

5:47

its particularity as yellow and through

5:50

it that the yellow becomes a universe or

5:53

an element. that a color can become a

5:56

level, a fact becomes a category exactly

6:01

as in music. Describe a note as

6:05

particular, i.e. in the field of another

6:08

tone, and the same note has become that

6:14

within whose key a music is written, the

6:18

veritable movement toward the universal.

6:21

The universal [music]

6:22

is not above, it is beneath. As in

6:24

cladell, it is not before but behind us.

6:29

Atonal music equals the equivalent of

6:33

the philosophy of being in indivision.

6:37

like paintings without identifiable

6:40

things without the skin of things but

6:43

giving their flesh. The transponyabakite

6:47

transposability

6:49

is a particular case of a more general

6:52

transposition of which [music] atonal

6:54

music is the thematization.

6:58

All this implies the being in

7:01

indivision.

7:04

This universality of the sensible or

7:07

presentation of what is not is or

7:09

presentable i.e. the original

7:13

presentation of what is not originally

7:16

presentable.

7:18

The sensible hollowed out in the being

7:20

without restriction. That being which is

7:23

between my perspective and that of the

7:26

other. My past and my present.

7:29

What is proper to the perceived to be

7:32

already there to not be through the act

7:36

of perception to be the reason for this

7:39

act and not the reverse. Sensorality is

7:43

transcendence or a mirror of

7:46

transcendence.

7:49

Depth

7:51

depth and back and behind

7:55

it is preeminently the dimension of the

7:58

hidden. Every dimension is of the

8:01

hidden.

8:02

There must be depth since there is a

8:05

point whence I see. Since the world

8:07

[music] surrounds me, depth is the means

8:11

the things have to remain distinct, to

8:14

remain things while not being what I

8:17

look at at present. It is preeminently

8:20

the dimension of the simultaneous.

8:23

Without it, there would not be a world

8:25

or being. There would only be a mobile

8:29

zone of distinctness which could not be

8:31

brought here without quitting all the

8:34

rest and a synthesis of these views.

8:39

Whereas by virtue of depth they coexist

8:42

in degrees of proximity. They slip into

8:45

one another and integrate themselves. It

8:48

is hence because of depth that the thing

8:51

has a flesh that is opposed to my

8:55

inspection obstacles a resistance which

8:59

is precisely their reality their

9:01

openness their totem simol

9:06

the look does not overcome depth it goes

9:10

around it depth is

9:13

stiffen originally given or originally

9:17

founded

9:18

Depth is originally founded in what I

9:21

see in clear vision as retention is in

9:24

the present without intentionality.

9:29

CF Mezer saying that it arises at the

9:32

moment when it was going to be

9:34

impossible to have a direct vision of

9:38

two points at the same time. Then the

9:41

two images that are out of phase are not

9:44

superposable.

9:46

They suddenly take as profiles of the

9:50

same thing in depth.

9:54

This is not an act or an intentionality

9:59

which would go to an in itself and would

10:03

give only juxtaposed in itself.

10:08

It is in general and by virtue of a

10:11

field property that this identification

10:14

of two incompossible [music] views is

10:17

made and because depth is open to me

10:20

because I have this dimension so as to

10:24

move my look in it this openness.

10:29

And in another note from the same time,

10:31

philosophy has never spoken, I do not

10:34

say of passivity. We are not effects but

10:37

I would say of the passivity of our

10:40

activity as Valerie spoke of a body of

10:44

the spirit.

10:46

New as our initiatives may be they come

10:50

to birth at the heart of being. They are

10:53

connected onto the time that streams

10:56

forth in us supported on the pivots or

10:59

hinges of our life. Their soul's sense

11:04

is a direction. The soul always thinks

11:08

this is in it a property of its state.

11:13

It cannot not think because a [music]

11:15

field has been opened in which something

11:18

or the absence of something is always

11:20

inscribed.

11:22

This is not an activity of the soul, not

11:26

a production of thoughts in the plural.

11:29

And I am not even the author of that

11:32

hollow that forms within me by the

11:35

passage from the present to the

11:37

retention. It is not I who makes myself

11:40

think any more than it is I who makes my

11:44

heartbeat.

11:46

From there leaves the philosophy of

11:48

arinance

11:50

experience and pass to the philosophy of

11:53

orchift original founding or institution

11:59

uh direction of thought. This is not a

12:02

metaphor. There is no metaphor between

12:05

the visible and the invisible.

12:08

The invisible either my thought for

12:10

myself or the sensible given to the

12:12

other for me. Metaphor is too much or

12:16

too little. Too much if the invisible

12:18

[music] is really invisible. Too little

12:22

if it lends itself to transposition.

12:25

There is no metaphor. One because

12:28

thought involves a quasi locality that

12:31

has to be described. Locality not by

12:34

inference in the spacio temporal point

12:37

but locality by elastic tie. One cannot

12:42

say that a mind is here. But one can say

12:46

that it is not there. This negation

12:49

little by little extends to all parts of

12:51

the world and of the living body. And

12:54

yet there is a locality by investment.

12:58

And when all that is said, there is the

13:02

theater of apparation of the other. And

13:06

there is no metaphor too because the

13:09

originating locality even in what

13:11

concerns the things or the direction of

13:15

the movement of things is not

13:17

identifiable in objective space either.

13:22

Not a relation in objective space. A

13:26

direction is not in space. It is in

13:30

filigree across it. It is therefore

13:33

transposable to thought.

13:36

The mind is neither here nor here nor

13:40

here. And yet it is attached, bounded.

13:43

It is not without bounds. Negation of

13:46

negation and position. One does not have

13:50

to choose between them. The mind is in

13:53

no objective sight, and yet it is

13:56

invested in a sight which it rejoins by

14:00

its environs which it circumvents as my

14:05

locality for myself is the point that

14:08

all the vanishing lines of my landscapes

14:11

designates to me and which is itself

14:15

invisible.

14:17

And finally, I'll read from December

14:19

1959,

14:21

a note on linen.

14:23

In denying the conception of perception,

14:26

reproduction on my body in itself, of

14:29

the exterior thing in itself, I open up

14:32

access to a brute being [music]

14:35

which I would not be in the subject and

14:38

object relation, and still less in the

14:41

relation of effect with cause.

14:45

In being in the world, relation will

14:47

take the place held in lienids by the

14:50

relation of reciprocal expression of the

14:53

perspectives [music] taken on the world

14:55

and hence God as the unique author of

14:58

these diverse perspectives which emanate

15:01

from him as thoughts. The being thus

15:04

discovered is to be sure not the god of

15:08

linenets. The monadology thus disclosed

15:13

is not the system of monads substances

15:16

but certain lienidsian descriptions that

15:20

each of the views of the world is a

15:22

world apart and that nevertheless what

15:25

is particular to one would be public to

15:28

all. And the monads would be [music] in

15:31

relation of expression between

15:32

themselves and with the world that they

15:36

differ from one another and from it as

15:39

perspectives are to be maintained

15:42

entirely to be taken up again in the

15:44

brute being to be separated from the

15:47

substantialist and onto theological

15:50

elaboration lienids [music] imposes upon

15:53

them. The expression of the universe in

15:55

us is certainly not the harmony between

15:57

our monad and the others. The presence

16:01

of the ideas of all things in it. But it

16:05

is what we see in perception to be taken

16:08

as such instead of explaining it. The

16:12

soul has no windows. That means being in

16:15

the world.

16:17

The pre-established harmony like

16:19

occasionalism

16:21

always maintains in itself and simply

16:25

connects it with what we experience

16:28

through a relation from substance to

16:30

substance founded in God instead of

16:33

making it the cause of our thoughts. But

16:36

it is precisely a question of rejecting

16:38

entirely the idea of the in itself.

16:43

It is the recovery of the theme of

16:46

perception that transforms the

16:48

significance of the lienzian idea of

16:51

expression.

16:53

Vertical world and vertical history.
