In order to analyse the different dimensions of individuality, I have tried to develop this theme of the presence of the infinite [l‚infini] in the philosophy of the seventeenth century, and the form under which this infinite presented itself. This theme is very fuzzy [flou] and I would like to draw from it some themes concerning the nature, this conception of the individual, this infinitist conception of the individual. Spinoza provides a perfect expression, as if he pushed those themes that were scattered among other authors of the seventeenth century to the end. In all its dimensions, the individual as Spinoza presents it, I would like to say three things about it. On the one hand, it is relation, on the other hand, it is power [puissance], and finally it is mode. But a very particular mode. A mode that one could call intrinsic mode.
The individual insofar as relation refers us to a whole plane that can be designated by the name of composition [compositio]. All individuals being relations, there is a composition of individuals among themselves, and individuation is inseparable from this movement of composition.
Second point, the individual is power [puissance Ų potentiae]. This is the second great concept of individuality. No longer composition that refers to relations, but potentiae.
We find the modus intrinsecus quite often in the Middle Ages, in certain traditions, under the name gradus. This is degree. The intrinsic mode or degree.
There is something common to these three themes: it's by virtue of this that the individual is not substance. If it's a relation it's not substance because substance concerns a term and not a relation. The substance is terminus, which is a term. If it's power it's not substance either because, fundamentally, whatever is substance is form. It's the form that is called substantial. And lastly, if it's degree it's not substance either since every degree refers to a quality that it graduates, every degree is degree of a quality. Now what determines a substance is a quality, but the degree of a quality is not substance.
You see that all this revolves around the same intuition of the individual as not being substance. I begin with the first character. The individual is relation. This is perhaps the first time in the history of the individual that an attempt to think relation in the pure state will be sketched out. But what does that mean, relation in the pure state? Is it possible, in some way, to think relation independently of its terms? What does a relation independent of its terms mean? There had already been a rather strong attempt in Nicholas of Cusa. In many of his texts that I find very beautiful, there was an idea that will be taken up again later. It seems to me that in his work it appeared in a fundamental way, that is, every relation is measure, only if every measure, every relation, plunges into the infinite. He dealt often with the measure of weight, with weighing, insofar as the relative measure of two weights refers to an absolute measure, and the absolute measure, itself, always brings the infinite into play. This is the theme that there is an immanence of pure relation and the infinite. One understands by "pure relation" the relation separate from its terms. Thus it's for this reason that it's so difficult to think pure relation independently of its terms. It's not because it's impossible, but because it puts into play a mutual immanence of the infinite and relation.
The intellect has often been defined as the faculty of setting out relations. Precisely in intellectual activity there is a kind of infinite that is implied [impliquť]. At the level of relation the implication of the infinite occurs through intellectual activity. What does that mean? Doubtless it will be necessary to wait until the seventeenth century to find a first statute of relation independent of its terms. This is what many philosophers, including those who made use of mathematical means, had sought since the Renaissance.
This will be brought to a first perfection thanks to the infinitesimal calculus. The infinitesimal calculus puts into play a certain type of relation. Which one? The method of exhaustion was like a kind of prefiguration of the infinitesimal calculus. The relation to which infinitesimal calculus gave a solid statute is what is called a differential relation, and a differential relation is of the type dy/dx =, we'll see what it's equal to.
How does one define this relation dy/dx = ? That which is called dy is an infinitely small quantity, or what is called a vanishing [ťvanouissante] quantity. A quantity smaller than any given or givable quantity. Whatever quantity of y you are given, dy will be smaller than this value. Thus I can say that dy as a vanishing quantity is strictly equal to zero in relation to y. In the same way dx is strictly equal to zero in relation to x. dx is the vanishing quantity of x. Thus I can write, and mathematicians do write dy/dx = 0/0. This is the differential relation.
If I call y a quantity of the abscissa and x a quantity of the ordinate, I would say that dy=0 in relation to the abscissa, dx=0 in relation to the ordinate. Is dy/dx equal to zero?
Obviously not. dy is nothing in relation to y, dx is nothing in relation to x, but dy over dx does not cancel out. The relation subsists and the differential relation will present itself as the subsistence of the relation when the terms vanish. They have found the mathematical convention that allows them to treat relations independently of their terms. Now what is this mathematical convention? I summarize. It's the infinitely small. Pure relation thus necessarily implies the infinite under the form of the infinitely small since pure relation will be the differential relation between infinitely small quantities. It's at the level of the differential relation that the reciprocal immanence of the infinite and relation is expressed in the pure state. dy/dx = 0/0 but 0/0 is not 0.
Indeed, what subsists when y and x cancel out under the form dy and dx, what subsists is the relation dy/dx itself, which is not nothing.
Now what does this relation dy/dx designate?
To what is it equal?
We will say that dy/dx equals z, that is to say it does not involve y or x at all, since it's y and x under the form of vanishing quantities. When you have a relation dy/dx derived from a circle, this relation dy/dx = 0/0 doesn't involve the circle at all but refers to what is called a trigonometric tangent.
One comprehends that dy/dx = z, that is to say the relation that is independent of its terms will designate a third term and will serve in the measurement and in the determination of a third term: the trigonometric tangent. In this sense I can say that the infinite relation, that is to say the relation between the infinitely small, refers to something finite. The mutual immanence of the infinite and relation is in the finite. Its in the finite itself that there is immanence of relation and the infinitely small. In order to gather together these three terms, pure relation, the infinite and the finite, I would say that the differential relation dy/dx tends towards a limit, and this limit is z, that is to say the determination of the trigonometric tangent. We are inside an extraordinarily rich knot of notions. Then afterward the mathematicians will say no, it's barbaric to interpret infinitesimal calculus by the infinitely small, it's not that. Perhaps they're right from a certain point of view, but this is to pose the problem badly. The fact is that the seventeenth century, by way of its interpretation of infinitesimal calculus, finds a means of fusing three key concepts, for mathematics and philosophy at the same time.
These three key concepts are the concepts of the infinite, relation and limit. Thus if I extract a formula of the infinite from the seventeenth century, I would say that something finite consists of an infinity [infinitť] under a certain relation. This formula can appear totally dull: something finite consists in the infinite under a certain relation, when in fact it is extraordinarily original. It marks an equilibrium point, for seventeenth-century thought, between the infinite and the finite, by way of a new theory of relations. And then when these later sorts consider it as going without saying that in the least finite dimension there is the infinite; when thereafter they speak of the existence of God all the time but this is much more interesting than is believed it doesn't finally involve God, it involves the richness of this implication of concepts: relation, infinite, limit.
How is the individual a relation? You will find, at the level of the individual, a limit. This does not prevent there having been some infinite, this does not prevent there being relations and these relations being composed, the relations of one individual are composed with another; and there is always a limit that marks the finitude of the individual, and there is always an infinite of a certain order that is involved by the relation.
It's a funny vision of the world. They didn't merely think like that, they saw like that. It was their very own taste, their way of treating things. When they see what microscopes show them, they see a confirmation of it: the microscope is the instrument that gives us a sensible and confused presentiment of this activity of the infinite under any finite relation. And Pascal's text on the infinite, he was a great mathematician as well, but when he needs to let us know how he sees the world, he doesn't need his mathematical knowledge [savoir] at all, the two reinforce each other. Then Pascal can make up his text on the two infinites without any reference to mathematics whatsoever. He says extremely simple but extremely original things. And indeed, the originality lies in this way of fusing three concepts: relation, limit, infinite.
This makes a funny world. We no longer think like that. What has changed is a whole system of mathematics as conventions, but that has changed only if you comprehend that modern mathematics also plots its concepts on a set of notions of another, equally original type.
[Following a remark] The limit towards which the relation tends is the reason for knowing [conn‚itre] the relation as independent of its terms, that is to say dx and dy, and the infinite, the infinitely small is the reason for being [raison d‚Ítre] of relation; indeed, it's the reason for being of dy/dx.
Descartes' formula: the infinite conceived and not comprehended. One does not comprehend the infinite because it is incomprehensible, but one conceives it. This is Descartes' great formula: one can conceive it clearly and distinctly, but comprehending it is something else. Thus one conceives it, there is a reason for knowledge [connaissance] of the infinite. There is a reason for knowing that is distinct from the reason for being. Comprehending would be grasping the reason for being, but we cannot grasp the reason for being of the infinite because to do so we would have to be adequate to God; but our understanding is merely finite. On the other hand, one can conceive the infinite, conceive it clearly and distinctly, thus one has a reason for knowing it.
Practical exercises in philosophy would have to be thought experiments [expťriences]. This is a German notion: experiments that one can only do in thought.
Let's pass on to the second point. I've had to invoke the notion of limit. Indeed, in order to account for the immanence of the infinite in relation, I return to the preceding point. The logic of relations [rapports], of relationships [relations] is a fundamental thing for philosophy, and alas, French philosophy has never been very interested in this aspect. But the logic of relations has been one of the great creations of the English and the Americans. But there were two stages. The first stage is Anglo-Saxon, the logic of relations such as it was built up on the basis of Russell at the end of the nineteenth century; now this logic of relations claims to be founded on this: the independence of relation in relation to its terms, but this independence, this autonomy of relation in relation to its terms is founded on finite considerations. They are founded on a finitism. Russell even has an atomist period in order to develop his logic of relations.
This stage had been prepared by a very different stage.
The great classical stage of the theory of relations is not like they say; they say that earlier, people confused the logic of relations and the logic of attribution. They confused two types of judgment: judgments of relation (Pierre is smaller than Paul) and judgments of attribution (Pierre is yellow or white), thus they had no consciousness of relations. It's not like that at all.
In so-called classical thought, there is a fundamental realization of the independence of relation in relation to relationships, only this realization passes by way of the infinite. The thought of relation as pure relation can only be made in reference to the infinite. This is one of the highly original moments of the seventeenth century.
I return to my second theme: the individual is power [puissance]. The individual is not form, it is power. Why does this follow? It's what I just said about the differential relation 0/0, which is not equal to zero but tends towards a limit.
When you say that, the tension towards a limit, you rediscover this whole idea of the tendency in the seventeenth century in Spinoza at the level of a Spinozist concept, that of conatus. Each thing tends to persevere in its being. Each thing strives [s‚efforce]. In Latin, "strive" is "conor," the effort or tendency, the conatus. The limit is being defined according to an effort, and power is the same tendency or the same effort insofar as it tends towards a limit.
If the limit is grasped on the basis of the notion of power, namely tending towards a limit, in terms of the most rudimentary infinitesimal calculus, the polygon that multiplies its sides tends towards a limit, which is the curved line. The limit is precisely the moment when the angular line, by dint of multiplying its sides, tends towards infinity [l‚infini]. It's the tension towards a limit that now implies the infinite. The polygon, as it multiplies its sides to infinity, tends towards the circle.
What change does this bring about in the notion of limit?
The limit was a well-known notion. One did not speak of tending towards a limit. The limit is a key philosophical concept. There is a veritable mutation in the manner of thinking a concept. What was limit? In Greek it's "peras." At the simplest level, the limit is the outlines [contours]. It‚s the time limits [termes]. Surveyors [GťomŤtres]. The limit is a term, a volume has surfaces for its limits. For example, a cube is limited by six squares. A line segment is limited by two endpoints. Plato has a theory of the limit in the Timeus: the figures and their outlines. And why can this conception of the limit as outline be considered as the basis for what one could call a certain form of idealism? The limit is the outline of the form, whether the form is purely thought or sensible, in any case one will call "limit" the outline of the form, and this is very easily reconciled with an idealism because if the limit is the outline of the form, after all what I can do is what there is between the limits. If I were to put some sand, some bronze or some thought matter, some intelligible matter, between my limits, this will always be a cube or a circle. In other words, essence is the form itself related to its outline. I could speak of the pure circle because there is a pure outline of the circle. I could speak of a pure cube without specifying what it involves. I would name these the idea of the circle, the idea of the cube. Hence the importance of "peras"-outline in Plato‚s philosophy in which the idea will be the form related to its intelligible outline.
In other words, in the idea of an outline-limit, Greek philosophy finds a fundamental confirmation for its own proper abstraction. Not that it is more abstract than another philosophy, but it sees the justification of the abstractio, such as it conceives it, namely the abstraction of ideas.
Henceforth the individual will be the form related to its outline. If I look for something to which such a conception concretely applies, I would say, regarding painting for example, that the form related to its outline is a tactile-optical world. The optical form is related, be it only by the eye, to a tactile outline. Then that can be the finger of pure spirit, the outline inevitably has a kind of tactile reference, and if one speaks of the circle or the cube as a pure idea, to the extent that one defines it by its outline and one relates the intelligible form to its outline, there is a reference however indirect it may be to a tactile determination. It is completely wrong to define the Greek world as the world of light, it's an optical world, but not at all a pure optical world. The word that the Greeks use to speak of the "idea" already sufficiently attests to the optical world that they promote: Eidos. Eidos is a term that refers to visuality, to the visible. The sight of spirit, but this sight of spirit is not purely optical. It is optical-tactile. Why? Because the visible form is related, however indirectly it may be, to the tactile outline.
It's not surprising that one of those who reacts against Platonic idealism, in the name of a certain technological inspiration, is Aristotle. But if you consider Aristotle, there the tactile reference of the Greek optical world appears quite evidently in an extremely simple theory which consists in saying that substance, or rather sensible substances are composites of form and matter, and it's the form that's essential. And the form is related to its outline, and the experience constantly invoked by Aristotle is that of the sculptor. Statuary has the greatest importance in this optical world; it's an optical world, but a world of sculpture, that is to say one in which the form is determined according to a tactile outline. Everything happens as if the visible form were unthinkable outside of a tactile mold. That is the Greek equilibrium. It's the Greek tactilo-optical equilibrium.
The eidos is grasped by the soul. The eidos, the pure idea is obviously graspable only by the pure soul. As pure soul we can only speak of it, according to Plato himself, by analogy, seeing that we only experiment with our soul insofar as it is bound to a body, we can only speak of it by analogy. Thus, from the point of view of analogy, I would always have said okay, it‚s the pure soul that grasps the pure idea. Nothing corporeal. It's a purely intellectual or spiritual grasp. But does this pure soul that grasps the idea proceed in the manner of an eye, in the manner of, or does it proceed rather in the manner of the sense of touch? Touch which would then be purely spiritual, like the eye which would be purely spiritual. This eye is the third eye. This would be a manner of speaking, but we definitely need the analogy. In Plato we definitely need analogical reasoning. Then all my remarks consist in saying that the pure soul no more has an eye than it has a sense of touch, it is in relation with the ideas. But this does not prevent the philosopher, in order to speak of this apprehension of the idea by the soul, from having to ask himself what is the role of an analogon of the eye and an analogon of touch? An analogue of the eye and an analogue of touch in the grasping of the idea. There are then these two analoga since the idea is constantlyē[gap in recording]
This was the first conception of the outline-limit. But what happens when, several centuries later, one gets a completely different conception of the limit, and the most varied signs come to us from it?
First example, from the Stoics. They lay into Plato quite violently. The Stoics are not the Greeks, they are at the edge [pourtour] of the Greek world. And this Greek world has changed a lot. There had been the problem of how to develop the Greek world, then Alexander. These Stoics are attacking Plato, there is a new Oriental current. The Stoics tell us that we don't need Plato and his ideas, it's an indefensible conception. The outline of something is what? It's non-being, say the Stoics. The outline of something is the spot where the thing ceases to be. The outline of the square is not at all the spot where the square ends. You see that it's very strong as an objection. They take literally this Platonism that I‚ve sketched out quite summarily, namely that the intelligible form is the form related to a spiritual touch [tact], that is to say it's the figure related to the outline. They will say, like Aristotle, that the example of the sculptor is completely artificial. Nature never proceeds by molding. These examples are not relevant, they say. In what cases does nature proceed by way of molds, it would be necessary to count them, it‚s certainly only in superficial phenomena that nature proceeds by way of molds. These are phenomena that are called superficial precisely because they affect surfaces, but nature, in depth [profondeur], does not proceed by way of molds. I am pleased to have a child who resembles me; I have not sent out a mold. Notice that biologists, until the eighteenth century, cling to the idea of the mold. They insisted on the spermatozoon analogous to a mold, this is not reasonable. On that point Buffon had great ideas; he said that if one wants to comprehend something of the production of living things, it would be necessary to work one‚s way up to the idea of an internal mold. Buffon‚s concept of an "internal mold" could help us. It means what? It's awkward because one could just as well speak of a massive surface. He says that the internal mold is a contradictory concept. There are cases in which one is obliged to think by means of a contradictory concept. The mold, by definition, is external. One does not mold the interior, which is to say that for the living thing, the theme of the mold already does not work. Nevertheless there is a limit to the living thing. The Stoics are in the process of getting hold of something very strong, life does not proceed by molding. Aristotle took artificial examples. And on Plato they let loose even more: the idea of the square, as if it were unimportant that the square was made of wood, or of marble, or of whatever you like. But this matters a lot. When one defines a figure by its outlines, the Stoics say, at that very moment everything that happens inside is no longer important. It's because of this, the Stoics say, that Plato was able to abstract the pure idea. They denounce a kind of sleight-of-hand [tour de passe-passe]. And what the Stoics are saying stops being simple: they are in the process of making themselves a totally different image of the limit. What is their example, opposed to the optical-tactile figure? They will oppose problems of vitality. Where does action stop? At the outline. But that, that holds no interest. The question is not at all where does a form stop, because this is already an abstract and artificial question. The true question is: where does an action stop?
Does everything have an outline? Bateson, who is a genius, has written a short text that is called "[why] does everything have an outline?" Take the expression "outside the subject," that is to say "beyond the subject." Does that mean that the subject has an outline? Perhaps. Otherwise what does "outside the limits" mean? At first sight it has a spatial air. But is it the same space? Do "outside the limits" and "outside the outline" belong to the same space? Does the conversation or my course today have an outline? My reply is yes. One can touch it.
Let's return to the Stoics. Their favorite example is: how far does the action of a seed go? A sunflower seed lost in a wall is capable of blowing out that wall. A thing with so small an outline. How far does the sunflower seed go, does that mean how far does its surface go? No, the surface is where the seed ends. In their theory of the utterance [ťnoncť], they will say that it states exactly what the seed is not. That is to say where the seed is no longer, but about what the seed is it tells us nothing. They will say of Plato that, with his theory of ideas, he tells us very well what things are not, but he tells us nothing about what things are.
The Stoics cry out triumphantly: things are bodies.
Bodies and not ideas. Things are bodies, that meant that things are actions. The limit of something is the limit of its action and not the outline of its figure. Even simpler example: you are walking in a dense forest, you're afraid. At last you succeed and little by little the forest thins out, you are pleased. You reach a spot and you say, "whew, here's the edge." The edge of the forest is a limit. Does this mean that the forest is defined by its outline? It's a limit of what? Is it a limit to the form of the forest? It's a limit to the action of the forest, that is to say that the forest that had so much power arrives at the limit of its power, it can no longer lie over the terrain, it thins out.
The thing that shows that this is not an outline is the fact that we can't even specify the precise moment at which there is no more forest. There was a tendency, and this time the limit is not separable, a kind of tension towards the limit. It's a dynamic limit that is opposed to an outline limit. The thing has no other limit than the limit of its power [puissance] or its action. The thing is thus power and not form. The forest is not defined by a form, it is defined by a power: power to make the trees continue up to the moment at which it can no longer do so. The only question that I have to ask of the forest is: what is your power? That is to say, how far will you go?
That is what the Stoics discover and what authorizes them to say: everything is a body. When they say that everything is a body, they don't mean that everything is a sensible thing, because they do not emerge from the Platonic point of view. If they were to define the sensible thing by form and outline, that would hold no interest. When they say that everything is a body, for example a circle does not extend in space in the same fashion if it is made of wood as it does if it is made of marble. Further, "everything is a body" will signify that a red circle and a blue circle do not extend in space in the same fashion. Thus it's tension.
When they say that all things are bodies, they mean that all things are defined by tonos, the contracted effort that defines the thing. The kind of contraction, the embryonic force that is in the thing, if you don't find it, you don't know [connaissez] the thing. What Spinoza takes up again with the expression "what can a body do?"
Other examples. After the Stoics, at the beginning of Christianity a quite extraordinary type of philosophy developes: the Neo-Platonic school. The prefix "neo" is particularly well founded. It‚s in applying themselves to some extremely important Platonic texts that the Neo-Platonists will completely decenter all of Platonism. So much so that, in a certain sense, one could say that all of it was already in Plato. Only it was as though taken into a set that was not Plato‚s.
The Enneads have been inherited from Plotinus. Skim through Ennead four, book five. You will see a kind of prodigious course on light. A prodigious text in which Plotinus will try to show that light can be comprehended neither as a function of the emitting body nor as a function of the receiving body. His problem is that light makes up a part of these odd things that, for Plotinus, are going to be the true ideal things. One can no longer say that it begins there and ends there. Where does light begin? Where does light end?
Why couldn't one say the same thing three centuries earlier? Why did this appear in the so-called Alexandrine world? It's a manifesto for a pure optical world. Light has no tactile limit, and nevertheless there is certainly a limit. But this is not a limit such that I could say it begins there and it ends there. I couldn't say that. In other words, light goes as far as its power goes.
Plotinus is hostile to the Stoics, he calls himself a Platonist. But he had a premonition of the kind of reversal [retournement] of Platonism that he is in the process of making. It's with Plotinus that a pure optical world begins in philosophy. Idealities will no longer be only optical. They will be luminous, without any tactile reference. Henceforth the limit is of a completely different nature. Light scours the shadows. Does shadow form part of light? Yes, it forms a part of light and you will have a light-shadow gradation that will develop space. They are in the process of finding that deeper than space there is spatialization. Plato didn't know [savait] of that. If you read Plato's texts on light, like the end of book six of the Republic, and set it next to Plotinus 's texts, you see that several centuries had to pass between one text and the other. These nuances are necessary. It's no longer the same world. You know [savez] it for certain before knowing why, that the manner in which Plotinus extracts the texts from Plato develops for himself a theme of pure light. This could not be so in Plato. Once again, Plato's world was not an optical world but a tactile-optical world. The discovery of a pure light, of the sufficiency of light to constitute a world implies that, beneath space, one has discovered spatialization. This is not a Platonic idea, not even in the Timeus. Space grasped as the product of an expansion, that is to say that space is second in relation to expansion and not first. Space is the result of an expansion, that is an idea that, for a classical Greek, would be incomprehensible. It‚s an idea that comes from the Orient. That light could be spatializing: it's not light that is in space, it's light that constitutes space. This is not a Greek idea.
Several centuries later a tremendously important art form, Byzantine art, burst forth. It's a problem for art critics to figure out how Byzantine art remains linked to classical Greek art while at the same time, from another point of view, it breaks completely with classical Greek art. If I take the best critic in this regard, Riegl, he says something rigorous, in Greek art you have the priority of the foreground [avant-plan]. The difference between Greek art and Egyptian art is that in Greek art the distinction is made between the foreground and the background [arriŤre-plan], while in Egyptian art, broadly speaking, the two are on the same plane [plan]. The bas-relief. I summarize quite briefly. Greek art is the Greek temple, it's the advent of the cube. For the Egyptians it was the pyramid, plane surfaces. Wherever you set yourself you are always on a plane surface. It's diabolical because it's a way of hiding the volume. They put the volume in a little cube which is the funerary chamber, and they set up plane surfaces, isosceles triangles, to hide the cube. The Egyptians are ashamed of the cube. The cube is the enemy, the black, the obscure, it's the tactile. The Greeks invent the cube. They make cubical temples, that is to say they move the foreground and the background forward. But, Riegl says, there is a priority of the foreground, and the priority of the foreground is linked to the form because it's the form that has the outline. It's for this reason that he will define the Greek world as a tactile-optical world. With the Byzantines it's quite odd. They nestle [nichent] the mosaics, they move them back. There is no depth in Byzantine art, and for a very simple reason, it's that depth is between the image and me. All of Byzantine depth is the space between the spectator and the mosaic. If you suppress this space it's as if you were to look at a painting outside of every condition of perception, it's unbearable.
The Byzantines mount an enormous forced takeover. They privilege the background, and the whole figure will arise from the background. The whole image will arise from the background. But at that very moment, as if by chance, the formula of the figure or the image is no longer form-outline. Form-outline was for Greek sculpture. And nevertheless there is a limit, there are even outlines, but this is not what acts, the work no longer acts that way, contrarily to Greek statuary in which the outline captures the light. For Byzantine mosaic it's light-color, that is to say that what defines, what marks the limits is no longer form-outline but rather the couple light-color, that is to say that the figure goes on as far as the light that it captures or emits goes, and as far as the color of which it's composed goes.
The effect on the spectator is prodigious, namely that a black eye goes exactly as far as this black shines. Hence the expression of these figures whose faces are consumed by the eyes.
In other words there is no longer an outline of the figure, there is an expansion of light-color. The figure will go as far as it acts by light and by color. It's the reversal [renversement] of the Greek world. The Greeks wouldn't have known [su] how or wouldn't have wanted to proceed to this liberation of light and color. With Byzantine art color and light are liberated in relation to space because what they discover is that light and color are spatializing. Thus art must not be an art of space, it must be an art of the spatialization of space. Between Byzantine art and Plotinus slightly earlier texts on light there is an obvious resonance. What is affirmed is the same conception of the limit.
There is an outline-limit and there is a tension-limit. There is a space-limit and there is a spatialization-limit.
