(e.) (No body could subsist without the power of the universal soul.) Besides no body could subsist without the power of the universal Soul (from Numenius). Every body, indeed, is in a perpetual flow and movement (as thought Heraclitus, in Plato, Cratylus), and the world would soon perish if it contained nothing but bodies, even if some one of them were to be called soul; for such a soul, being composed of the same matter as the other bodies, would undergo the same fate that they do; or rather, there would not even be any body, everything would remain in the condition of shapeless matter, since there would exist no principle to fashion it. Why, there would not even be any matter, and the universe would be annihilated to nothingness, if the care of keeping its parts united were entrusted to some body which would have nothing but the name of soul, as for instance, to air, or a breath without cohesion, which could not be one, by itself. As all bodies are divisible, if the universe depended on a body, it would be deprived of intelligence and given up to chance. How, indeed, could there be any order in a spirit which itself would need to receive order from a soul? How could this spirit contain reason and intelligence? On the hypothesis of the existence of the soul, all these elements serve to constitute the body of the world, and of every animal, because all different bodies together work for the end of all; but without the soul, there is no order, and even nothing exists any more. [Ennead IV,7 (2) 3]

(j.) (The soul, being one and simple, is everywhere entire, and has parts that are identical to the whole; this is not the case with the body.) If the soul is a body, she will have parts that are not identical with the whole, as every body is by nature divisible. If then the soul has a definite magnitude of which she cannot lose anything without ceasing to be a soul, she will by losing her parts, change her nature, as happens to every quantity. If, on losing some part of its magnitude, a body, notwithstanding, remains identical in respect to quality, it does not nevertheless become different from what it was, in respect to quantity, and it remains identical only in respect to quality, which differs from quantity. What shall we answer to those who insist that the soul is a body? Will they say that, in the same body, each part possesses the same quality as the total soul, and that the case is similar with the part of a part? Then quantity is no longer essential to the nature of the soul; which contradicts the hypothesis that the soul needed to possess a definite magnitude. Besides the soul is everywhere entire; now it is impossible for a body to be entire in several places simultaneously, or have parts identical to the whole. If we refuse the name of soul to each part, the soul is then composed of inanimate parts. Besides, if the soul is a definite magnitude, she cannot increase or diminish without ceasing to be a soul; but it often happens that from a single conception or from a single germ are born two or more beings, as is seen in certain animals in whom the germs divide; in this case, each part is equal to the whole. However superficially considered, this fact demonstrates that the principle in which the part is equal to the whole is essentially superior to quantity, and must necessarily lack any kind of quantity. On this condition alone can the soul remain identical when the body loses its quantity, because she has need of no mass, no quantity, and because her essence is of an entirely different nature. The soul and the (seminal) reasons therefore possess no extension. [Ennead IV,7 (2) 5]

The subject that perceives a sense-object must itself be single, and grasp this object in its totality, by one and the same power. This happens when by several organs we perceive several qualities of a single object, or when, by a single organ, we embrace a single complex object in its totality, as, for instance, a face. It is not one principle that sees the face, and another one that sees the eyes; it is the “same principle” which embraces everything at once. Doubtless we do receive a sense-impression by the eyes, and another by the ears; but both of them must end in some single principle. How, indeed, could any decision be reached about the difference of sense-impressions unless they all converged toward the same principle? The latter is like a centre, and the individual sensations are like radii which from the circumference radiate towards the centre of a circle. This central principle is essentially single. If it was divisible, and if sense-impressions were directed towards two points at a distance from each other, such as the extremities of the same line, they would either still converge towards one and the same point, as, for instance, the middle (of the line), or one part would feel one thing, and another something else. It would be absolutely as if I felt one thing, and you felt another, when placed in the presence of one and the same thing (as thought Aristotle, de Anima). Facts, therefore, demonstrate that sensations centre in one and the same principle; as visible images are centred in the pupil of the eye; otherwise how could we, through the pupil, see the greatest objects? So much the more, therefore, must the sensations that centre in the (Stoic) “directing principleresemble indivisible intuitions and be perceived by an indivisible principle. If the latter possessed extension, it could, like the sense-object, be divided; each of its parts would thus perceive one of the parts of the sense-object, and nothing within us would grasp the object in its totality. The subject that perceives must then be entirely one; otherwise, how could it be divided? In that case it could not be made to coincide with the sense-object, as two equal figures superimposed on each other, because the directing principle does not have an extension equal to that of the sense-object. How then will we carry out the division? Must the subject that feels contain as many parts as there are in the sense-object? Will each part of the soul, in its turn, feel by its own parts, or will (we decide that) the parts of parts will not feel? Neither is that likely. If, on the other hand, each part feels the entire object, and if each magnitude is divisible to infinity, the result is that, for a single object, there will be an infinity of sensations in each part of the soul; and, so much the more, an infinity of images in the principle that directs us. (This, however, is the opposite of the actual state of affairs.) [Ennead IV,7 (2) 6]

If, in any sense whatever, the soul were a body, we could not think. Here is the proof. If feeling is explained as the soul’s laying hold of perceptible things by making use of the body, thinking cannot also of making use of the body. Otherwise, thinking and feeling would be identical. Thus, thinking must consist in perceiving without the help of the body (as thought Aristotle). So much the more, the thinking principle cannot be corporeal. Since it is sensation that grasps sense-objects, it must likewise be thought, or intellection, that grasps intelligible objects. Though this should be denied, it will be admitted that we think certain intelligibles entities, and that we perceive entities that have no extension. How could an entity that had extension think one that had no extension? Or a divisible entity, think an indivisible one? Could this take place by an indivisible part? In this case, the thinking subject will not be corporeal; for there is no need that the whole subject be in contact with the object; it would suffice if one of its parts reached the object (as Aristotle said against Plato). If then this truth be granted, that the highest thoughts must have incorporeal objects, the latter can be cognized only by a thinking principle that either is, or becomes independent of body. Even the objection that the object of thought is constituted by the forms inherent in matter, implies that these forces cannot be thought unless, by intelligence, they are separated from matter. It is not by means of the carnal mass of the body, nor generally by matter, that we can effect the abstraction of triangle, circle, line or point. To succeed in this abstraction, the soul must separate from the body, and consequently, the soul cannot be corporeal. [Ennead IV,7 (2) 8]

(10). The soul penetrates the whole body, while an entire body cannot penetrate another entire body. Further, if the soul is corporeal, and pervades the whole body, she will, with the body, form (as Alexander of Aphrodisia pointed out) a mixture, similar to the other bodies (that are constituted by a mixture of matter and quality, as the Stoics taught). Now as none of the bodies that enter into a mixture is in actualization the soul, instead of being in actualization in the bodies, would be in them only potentially; consequently, she would cease to be a soul, as the sweet ceases to be sweet when mingled with the bitter; we would, therefore, have no soul left. If, when one body forms a mixture with another body, total penetration occurs, so that each molecule contains equal parts of two bodies and that each body be distributed equally in the whole space occupied by the mass of the other, without any increase of volume, nothing that is not divided will remain. Indeed, mixture operates not only between the larger parts (which would be no more than a simple juxtaposition); but the two bodies must penetrate each other mutually, even if smaller — it would indeed be impossible for the smaller to equal the greater; still, when the smaller penetrates the larger it must divide it entirely. If the mixture operates in this manner in every part, and if no undivided part of the mass remain, the body must be divided into points, which is impossible. Indeed, were this division pushed to infinity, since every body is fully divisible, bodies will have to be infinite not only potentially, but also in actuality. It is therefore impossible for one entire body to penetrate another in its entirety. Now as the soul penetrates the entire body, the soul must be incorporeal (as thought Nemesius). [Ennead IV,7 (2) 8]

Besides, as the soul is indivisible, the entelechy of the divisible body could not become divisible as is the body. Besides, the same soul passes from the body of one animal into the body of some other. How could the soul of the first become that of the second, if she were only the entelechy of a single one? The example of animals that metamorphose demonstrates the impossibility of this theory. The soul, therefore, is not the simple form of a body; she is a genuine “being,” which does not owe its existence merely to her being founded on the body, but which, on the contrary, exists before having become the soul of some individual animal. It is, therefore, not the body that begets the soul. [Ennead IV,7 (2) 8]

It is in the intelligible world that dwells veritable being. Intelligence is the best that there is on high; but there are also souls; for it is thence that they descended thither. Only, souls have no bodies, while here below they inhabit bodies and are divided there. On high, all the intelligences exist together, without separation or division; all the souls exist equally together in that world which is one, and there is no local distance between them. Intelligence therefore ever remains inseparable and indivisible; but the soul, inseparable so long as she resides on high, nevertheless possesses a divisible nature. For her “dividing herself” consists in departing from the intelligible world, and uniting herself to bodies; it might therefore be reasonably said that she becomes divisible in passing into bodies, since she thus separates from the intelligible world, and divides herself somewhat. In what way is she also indivisible? In that she does not separate herself entirely from the intelligible world, ever residing there by her highest part, whose nature it is to be indivisible. To say then that the soul is composed of indivisible (essence) and of (essence) divisible in bodies means then no more than that the soul has an (essence) which dwells partly in the intelligible world, and partly descends into the sense-world, which is suspended from the first and extends downwards to the second, as the ray goes from the centre to the circumference. When the soul descended here below, it is by her superior part that she contemplates the intelligible world, as it is thereby that she preserves the nature of the all (of the universal Soul). For here below she is not only divisible, but also indivisible; her divisible part is divided in a somewhat indivisible manner; she is indeed entirely present in the whole body in an indivisible manner, and nevertheless she is said to divide herself because she spreads out entirely in the whole body. [Ennead IV,1 (4) 10]

It is therefore by no means necessary that when one member of the universe experiences an affection, the latter be clearly felt by the All. The existence of sympathy is natural enough, and it could not be denied; but this does not imply identity of sensation. Nor is it absurd that our souls, while forming a single one should be virtuous and vicious, just as it would be possible that the same essence be at motion in me, but at rest in you. Indeed, the unity that we attribute to the universal (Soul) does not exclude all multiplicity, such a unity as befits intelligence. We may however say that (the soul) is simultaneously unity and plurality, because she participates not only in divisible essence in the bodies, but also in the indivisible, which consequently is one. Now, just as the impression perceived by one of my parts is not necessarily felt all over my body, while that which happens to the principal organ is felt by all the other parts, likewise, the impressions that the universe communicates to the individual are clearer, because usually the parts perceive the same affections as the All, while it is not evident that the particular affections that we feel would be also experienced by the Whole. [Ennead IV,9 (8) 2]

If, however, the Soul be one, why is some one soul reasonable, another irrational, or some other one merely vegetative? The indivisible part of the soul consists in reason, which is not divided in the bodies, while the part of the divisible soul in the bodies (which, though being one in herself, nevertheless divides herself in the bodies, because she sheds sentiment everywhere), must be regarded as another power of the soul (the sensitive power); likewise, the part which fashions and produces the bodies is still another power (the vegetative power); nevertheless, this plurality of powers does not destroy the unity of the soul. For instance, in a grain of seed there are also several powers; nevertheless this grain of seed is one, and from this unity is born a multiplicity which forms a unity. [Ennead IV,9 (8) 3]

If the essence of each thing be manifoldness, and as unity cannot be manifoldness, unity must differ from essence. Now man, being both animal and rational, contains a manifoldness of elements of which unity is the bond. There is therefore a difference between man and unity; man is divisible, while unity is indivisible. Besides, universal Essence, containing all essences, is still more manifold. Therefore it differs from unity; though it does possess unity by participation. Essence possesses life and intelligence, for it cannot be considered lifeless; it must therefore be manifold. Besides, if essence be intelligence, it must in this respect also be manifold, and must be much more so if it contain forms; for the idea is not genuinely one. Both as individual and general it is rather a number; it is one only as the world is one. [Ennead VI,9 (9) 2]

In what sense do we use the name of unity, and how can we conceive of it? We shall have to insist that the One is a unity much more perfect than the point of the monad; for in these, abstracting (geometric) magnitude, and numerical plurality, we do indeed stop at that which is most minute, and we come to rest in something indivisible; but this existed already in a divisible being, in a subject other than itself, while the One is neither in a subject other than itself, nor in anything divisible. If it be indivisible, neither is it of the same kind as that which is most minute. On the contrary, it is that which is greatest, not by (geometric) magnitude, but by power; possessing no (geometric) magnitude, it is indivisible in its power; for the beings beneath it are indivisible in their powers, and not in their mass (since they are incorporeal). We must also insist that the One is infinite, not as would be a mass of a magnitude which could be examined serially, but by the incommensurability of its power. Even though you should conceive of it as of intelligence or divinity, it is still higher. When by thought you consider it as the most perfect unity, it is still higher. You try to form for yourself an idea of a divinity by rising to what in your intelligence is most unitary (and yet He is still simpler); for He dwells within Himself, and contains nothing that is contingent. [Ennead VI,9 (9) 6]

We call Intelligence the image of the One. Let us explain this. It is His image because Intelligence is, in a certain respect, begotten by Unity, because Intelligence possesses much of the nature of its father, and because Intelligence resembles Him as light resembles the sun. But the One is not Intelligence; how then can the hypostatic (form of existence) begotten by the One be Intelligence? By its conversion towards the One, Intelligence sees Him; now it is this vision which constitutes Intelligence. Every faculty that perceives another being is sensation or intelligence; but sensation is similar to a straight line, while intelligence resembles a circle. Nevertheless, the circle is divisible, while Intelligence is indivisible; it is one, but, while being one, it also is the power of all things. Now thought considers all these things (of which Intelligence is the power), by separating itself, so to speak, from this power; otherwise, Intelligence would not exist. Indeed, Intelligence has a consciousness of the reach of its power, and this consciousness constitutes its nature. Consequently, Intelligence determines its own nature by the means of the power it derived from the One; and at the same time Intelligence sees that its nature (“being”) is a part of the entities which belong to the One, and that proceed from Him. Intelligence sees that it owes all its force to the One, and that it is due to Him that Intelligence has the privilege of being a “being” (or, essence). Intelligence sees that, as it itself is divisible, it derives from the One, which is indivisible, all the entities it possesses, life and thought; because the One is not any of these things. Everything indeed is derived from the One, because it is not contained in a determinate form; it simply is the One, while in the order of beings Intelligence is all things. Consequently the One is not any of the things that Intelligence contains; it is only the principle from which all of them are derived. That is why they are “being,” for they are already determined, and each has a kind of shape. Existence should be contemplated, not in indetermination, but on the contrary in determination and rest. Now, for Intelligible entities, rest consists in determination, and shape by which they subsist. [Ennead V,1 (10) 7]

Since the rational soul makes judgments about what is just or beautiful, and decides whether some object is beautiful, whether such an action be just, there must exist an immutable justice and beauty from which discursive reason draws its principles. Otherwise, how could such reasonings take place? If the soul at times reasons about justice and beauty, but at times does not reason about them, we must possess within ourselves the intelligence which, instead of reasoning, ever possesses justice and beauty; further, we must within us possess the cause and Principle of Intelligence, the Divinity, which is not divisible, which subsists, not in any place, but in Himself; who is contemplated by a multitude of beings, by each of the beings fitted to receive Him, but which remains distinct from these beings, just as the centre subsists within itself, while all the radii come from the circumference to centre themselves in it. Thus we ourselves, by one of the parts of ourselves, touch the divinity, unite ourselves with Him and are, so to speak, suspended from Him; and we are founded upon Him (we are “edified” by Him) when we turn towards Him. [Ennead V,1 (10) 11]

Besides, our world is an image of the intelligible world. Now as our world is a composite of matter (and form), there must be matter also on high (that is, in the intelligible world). Otherwise, how could we call the intelligible worldkosmos” (that is, either world, or adornment), unless we see matter (receiving) form therein? How could we find form there, without (a residence) that should receive it? That world is indivisible, taken in an absolute sense; but in a relative sense, is it divisible? Now if its parts be distinct from each other, their division or distinction is a passive modification of matter; for what can be divided, must be matter. If the multitude of ideals constitute an indivisible being, this multitude, which resides in a single being, has this single being as substrate, that is, as matter and is its shapes. This single, yet varied substrate conceives of itself as shapeless, before conceiving of itself as varied. If then by thought you abstract from it variety, forms, reasons, and intelligible characteristics, that which is prior is indeterminate and shapeless; then there will remain in this (subject) none of the things that are in it and with it. [Ennead II,4 (12) 4]

(According to Aristotle’s account of Democritus), neither could the atoms fulfil the part of matter because they are nothing (as before thought Cicero). Every body is divisible to infinity. (Against the system of the atoms) might further be alleged the continuity and humidity of bodies. Besides nothing can exist without intelligence and soul, which could not be composed of atoms. Nothing with a nature different from the atoms could produce anything with the atoms, because no demiurgic creator could produce something with a matter that lacked continuity. Many other objections against this system have and can be made; but further discussion is unnecessary. [Ennead II,4 (12) 7]

We have already noticed two of these principles (namely, intelligence, and the intelligible, which is called the Animal-in-itself, or universal Soul). What is the third? It is he who has resolved to produce, to form, to divide the ideas that intelligence sees in the Animal. Is it possible that in one sense intelligence is the dividing principle, and that in another the dividing principle is not intelligence? As far as divided things proceed from intelligence, intelligence is the dividing principle. As far as intelligence itself remains undivided, and that the things proceeding from it (that is, the souls) are divided, the universal Soul is the principle of this division into several souls. That is why Plato says that division is the work of a third principle, and that it resides in a third principle that has conceived; now, to conceive is not the proper function of intelligence; it is that of the Soul which has a dividing action in a divisible nature. [Ennead III,9 (13) 1]

As to the souls which have left the sense-world, so long as they remain in the intelligible world, they are above the guardian condition, and the fatality of generation. Souls bring with them thither that part of their nature which is desirous of begetting, and which may reasonably be regarded as the essence which is divisible in the body, and which multiplies by dividing along with the bodies. Moreover, if a soul divide herself, it is not in respect to extension; because she is entirely in all the bodies. On the other hand, the Soul is one; and from a single animal are ceaselessly born many young. This generative element splits up like the vegetative nature in plants; for this nature is divisible in the bodies. When this divisible essence dwells in the same body, it vivifies the body, just as the vegetative power does for plants. When it retires, it has already communicated life, as is seen in cut trees, or in corpses where putrefaction has caused the birth of several animals from a single one. Besides, the vegetative power of the human soul is assisted by the vegetative power that is derived from the universal (Soul), and which here below is the same (as on high). [Ennead III,4 (15) 6]

To begin with, there are (beings) which are quite divisible and naturally separable. No one part of any one of them is identical with any other part, nor with the whole, of which each part necessarily is smaller than the whole. Such are sense-magnitudes, or physical masses, of which each occupies a place apart, without being able to be in several places simultaneously. [Ennead IV,2 (21) 1]

On the other hand, there exists another kind of essence (“being”), whose nature differs from the preceding (entirely divisible beings), which admits of no division, and is neither divided nor divisible. This has no extension, not even in thought. It does not need to be in any place, and is not either partially or wholly contained in any other being. If we dare say so, it hovers simultaneously over all beings, not that it needs to be built up on them, but because it is indispensable to the existence of all. It is ever identical with itself, and is the common support of all that is below it. It is as in the circle, where the centre, remaining immovable in itself, nevertheless is the origin of all the radii originating there, and drawing their existence thence. The radii by thus participating in the existence of the centre, the radii’s principle, depend on what is indivisible, remaining attached thereto, though separating in every direction. [Ennead IV,2 (21) 1]

Now between entirely indivisible (“Being”) which occupies the first rank amidst intelligible beings, and the (essence) which is entirely divisible in its sense-objects, there is, above the sense-world, near it, and within it, a “being” of another nature, which is not, like bodies, completely divisible, but which, nevertheless, becomes divisible within bodies. Consequently, when you separate bodies, the form within them also divides, but in such a way that it remains entire in each part. This identical (essence), thus becoming manifold, has parts that are completely separated from each other; for it then is a divisible form, such as colors, and all the qualities, like any form which can simultaneously remain entire in several things entirely separate, at a distance, and foreign to each other because of the different ways in which they are affected. We must therefore admit that this form (that resides in bodies) is also divisible. [Ennead IV,2 (21) 1]

Thus the absolutely divisible (essence) does not exist alone; there is another one located immediately beneath it, and derived from it. On one hand, this inferior (essence) participates in the indivisibility of its principle; on the other, it descends towards another nature by its procession. Thereby it occupies a position intermediary between indivisible and primary (essence), (that is, intelligence), and the divisible (essence) which is in the bodies. Besides it is not in the same condition of existence as color and the other qualities; for though the latter be the same in all corporeal masses, nevertheless the quality in one body is completely separate from that in another, just as physical masses themselves are separate from each other. Although (by its essence) the magnitude of these bodies be one, nevertheless that which thus is identical in each part does not exert that community of affection which constitutes sympathy, because to identity is added difference. This is the case because identity is only a simple modification of bodies, and not a “being.” On the contrary, the nature that approaches the absolutely indivisibleBeing” is a genuine “being” (such as is the soul). It is true that she unites with the bodies and consequently divides with them; but that happens to her only when she communicates herself to the bodies. On the other hand, when she unites with the bodies, even with the greatest and most extended of all (the world), she does not cease to be one, although she yield herself up to it entirely. [Ennead IV,2 (21) 1]

In no way does the unity of this essence resemble that of the body; for the unity of the body consists in the unity of parts, of which each is different from the others, and occupies a different place. Nor does the unity of the soul bear any closer resemblance to the unity of the qualities. Thus this nature that is simultaneously divisible and indivisible, and that we call soul is not one in the sense of being continuous (of which each part is external to every other); it is divisible, because it animates all the parts of the body it occupies, but is indivisible because it entirely inheres in the whole body, and in each of its parts. When we thus consider the nature of the soul, we see her magnitude and power, and we understand how admirable and divine are these and superior natures. Without any extension, the soul is present throughout the whole of extension; she is present in a location, though she be not present therein. She is simultaneously divided and undivided, or rather, she is never really divided, and she never really divides; for she remains entire within herself. If she seem to divide, it is not in relation with the bodies, which, by virtue of their own divisibility, cannot receive her in an indivisible manner. Thus division is the property of the body, but not the characteristic of the soul. [Ennead IV,2 (21) 1]

Such then the nature of the soul had to be. She could not be either purely indivisible, nor purely divisible, but she necessarily had to be both indivisible and divisible, as has just been set forth. This is further proved by the following considerations. If the soul, like the body, have several parts differing from each other, the sensation of one part would not involve a similar sensation in another part. Each part of the soul, for instance, that which inheres in the finger, would feel its individual affections, remaining foreign to all the rest, while remaining within itself. In short, in each one of us would inhere several managing souls (as said the Stoics). Likewise, in this universe, there would be not one single soul (the universal Soul), but an infinite number of souls, separated from each other. [Ennead IV,2 (21) 2]

On the other hand, if the soul were absolutely one, essentially indivisible and one within herself, if her nature were incompatible with manifoldness and division, she could not, when penetrating into the body, animate it in its entirety; she would place herself in its centre, leaving the rest of the mass of the animal lifeless. The soul, therefore, must be simultaneously one and manifold, divided and undivided, and we must not deny, as something impossible, that the soul, though one and identical, can be in several parts of the body simultaneously. If this truth be denied, this will destroy the “nature that contains and administers the universe” (as said the Stoics); which embraces everything at once, and directs everything with wisdom; a nature that is both manifold, because all beings are manifold; and single, because the principle that contains everything must be one. It is by her manifold unity that she vivifies all parts of the universe, while it is her indivisible unity that directs everything with wisdom. In the very things that have no wisdom, the unity that in it plays the predominating “part,” imitates the unity of the universal Soul. That is what Plato wished to indicate allegorically by these divine words: “From the “Being” that is indivisible and ever unchanging; and from the “being” which becomes divisible in the bodies, the divinity formed a mixture, a third kind of “being.” The (universal) Soul, therefore, is (as we have just said) simultaneously one and manifold; the forms of the bodies are both manifold and one; the bodies are only manifold; while the supreme Principle (the One), is exclusively an unity. [Ennead IV,2 (21) 2]

Is it because the body of the universe is so great that the Soul is everywhere present in the universe, though being naturally divisible in (human) bodies? Or it is by herself, that she is everywhere present? In the latter case, she has not been drawn away everywhere by the body, but the body found her everywhere in existence before it; thus, in whatever place it may be, it found the Soul present before it itself was part of the universe, and the total body of the universe was located in the Soul that existed already. [Ennead VI,4 (22) 1]

But if the Soul had such an extension before the body approached her, if she already filled all space, how can she have no magnitude? Besides, how could she have been present in the universe when the latter did not yet exist? Last, being considered indivisible and non-extended, is she everywhere present without having any magnitude? If the answer be that she extended herself throughout the body of the universe without herself being corporeal, the question is not yet resolved by thus accidentally attributing magnitude to the Soul; for it would then be reasonable to ask how she grew great by accident. The Soul could not extend herself in the entire body in the same manner as quality, as for instance, sweetness or color; for these are passive modifications of the bodies, so that one must not be astonished to see a modification spread all over the modified body, being nothing by itself, inhering in the body, and existing only within it; that is why the soul necessarily has the same magnitude as the body. Besides, the whiteness of one part of the body does not share the experience (or, “passion”) experienced by the whiteness of another part; the whiteness of one part is identical, in respect to species, to the whiteness of another part; but it is not identical therewith in respect to number; on the contrary, the part of the soul which is present in the foot is identical with the portion of the soul present in the hand, as may be seen in the percepts thereof. Last, what is identical in the qualities is divisible, while that which is identical in the soul is indivisible; if it be said to divide, it is in this sense that it is present everywhere. [Ennead VI,4 (22) 1]

Is the universal (Being) by itself present everywhere? Or does it remain within itself, while from its innermost its powers descend on all things, and is it in this sense that it is regarded as everywhere present? Yes, doubtless. That is why it is said that souls are the rays of this universal (Being), that it is built on itself, and that from it, souls descend into various animals. The things which participate in its unity, incapable as they are of possessing a complete nature conformed to its nature, enjoy the presence of the universal (Being) in this sense that they enjoy the presence of some of its powers. They are not, however, entirely separated from it, because it is not separated from the power which it communicates to each of them. If they do not have more, it is only because they are not capable of receiving more from the presence of the entire whole (Being). Evidently it is always entirely present there where its powers are present. It however remains separated, for if it became the form of any one particular being, it would cease to be universal, to subsist everywhere in itself, and it would be the accident of some otherbeing.” Therefore, since it belongs to none of these things, even of those that aspire to unite themselves with it, it makes them enjoy its presence when they desire it, and in the measure in which they are capable thereof; but it does not belong to any of them in particular. It is not surprising, therefore, that it should be present in all things, since it is not present in any in a manner such as to belong to it alone. It is also reasonable to assert that, if the soul share the passions of the bodies, it is only by accident, that she dwells in herself, and belongs neither to matter nor to body, that the whole of her illuminates the whole world-body. It is not a contradiction to say that the (Being) which is not present in any place is present to all things each of which is in a place. What, indeed, would be surprising and impossible would be that the universal (Being) could, while occupying a determinate place, be present to things which are in a place, and could at all be present in the sense in which we have explained it. Reason forces us, therefore, to admit that the universal (Being) must, precisely because it does not occupy any place, be entirely present to the things to which it is present; and, since it is present to the universe, be entirely present to each thing; otherwise, one part of it would be here, and another there; consequently, it would be divisible, it would be body. How otherwise could one divide the (“Being”)? Is it its life that shall within it be divided? If it be the totality of the (being) that is life, no part of it would be that. Or will somebody try to divide the Intelligence, so that one of its parts be here, and the other there? In this case, neither of the two parts would be intelligence. Or will the (Being) itself be divided? But if the totality be the (Being), no one part of it would be that. It might be objected that the parts of the bodies are still bodies themselves. But that which is divided is not the body (as such), but a certain body of a certain extent; now each of its parts possesses the form that causes it to be named body; while the form not only does not have some particular extension, but even any kind of extension at all. [Ennead VI,4 (22) 3]

Let us first explain how there can be a plurality of intelligences, souls, and essences. If we consider the things that proceed from the first principles, as they are numbers and not magnitudes, we shall also have to ask ourselves how they fill the universe. This plurality which thus arises from the first principles does not in any way help us to solve our question, since we have granted that essence is multiple because of the difference (of the beings that proceed from it), and not by place; for though it be multiple, it is simultaneously entire; “essence everywhere touches essence,” and it is everywhere entirely present. Intelligence likewise is manifold by the difference (of the intelligences that proceed therefrom), and not by space; it is entire everywhere. It is so also with souls; even their part which is divisible in the bodies is indivisible by its nature. But the bodies possess extension because the soul is present with them; or rather, it is because there are bodies in the sense-world; it is because the power of the Soul (that is universal) which is in them manifests itself in all their parts, that the Soul herself seems to have parts. What proves that she is not divided as they are, and with them, that she is entirely present everywhere, is that by nature she is essentially one and indivisible. Thus, the unity of the Soul does not exclude the plurality of souls, any more than the unity of essence excludes the plurality of (beings), or that the plurality of intelligibles does not disagree with the existence of the One. It is not necessary to admit that the Soul imparts life to the bodies by the plurality of souls, nor that that plurality derives from the extension of the body (of the world). Before there ever were any bodies, there was already one (universal) Soul and several (individual) souls. The individual souls existed already in the universal Soul, not potentially, but each in actuality. The unity of the universal Soul does not hinder the multitude of the individual souls contained within her; the multitude of the individual souls does not hinder the unity of the universal Soul. They are distinct without being separated by any interval; they are present to each other instead of being foreign to each other; for they are not separated from each other by any limits, any more than different sciences are within a single soul. The Soul is such that in her unity she contains all the souls. Such a nature is, therefore, infinite. [Ennead VI,4 (22) 4]

When light emanates from a body it is easy to tell when it shines, because the location of that body is known. But if a being be immaterial, if it have no need of a body, if it be anterior to all bodies, and be founded on itself, or rather if it have no need, as has a body, or resting on any foundation — then, a being endowed with such a nature has no origin from which it is derived, resides in no place, and depends on no body. How could you then say that one of its parts is here, and another is there? For thus it would have an origin from which it had issued, and it would depend from something. We must, therefore, say that if something participate in this being by the power of the universe, it participates in this being entirely, without thereby being changed or divided; for it is a being united to a body that suffers (although often that happens to it only accidentally), and in this respect it may be said that it is passive and divisible, since it is some part of the body, either its passion, or form. As to the (being) which is united to any body, and to which the body aspires to be united, it must in no manner share the passions of the body, as such; for the essential passion of the body, as such, is to divide itself. If, therefore, the body be by nature inclined to divide itself, then is the incorporeal, by nature, indivisible. How, in fact, could one divide that which has no extension? If, therefore, the extended (being) participate in the (being) which has no extension, it participates in this (being) without dividing it; otherwise, this (being) would have extension. Consequently, when you say that the unity (of the universal essence) is in the manifold, you do not say that unity has become manifoldness, but you refer to this unity the manner of existence of the multitude, seeing it in this whole multitude simultaneously. As to this Unity, it will have to be understood that it belongs to no individual, nor to the whole multitude, but that it belongs to itself alone, that it is itself, and that, being itself, it does not fail to support itself. Nor does it possess a magnitude such as of our universe, nor, let alone, such as that of one of the parts of the universe; for it has absolutely no magnitude. How could it have any magnitude? It is the body that should have such magnitude. As to the (being) whose nature is entirely different from that of the body, no magnitude should be ascribed to it. If it have no magnitude, it is nowhere; it is neither here nor there; for if so, it would be in several places. If then the local division suits only the (being) of which one part is here, and the other there, how could the (being) that is neither here nor there be divided? Consequently, the incorporeal (being) must remain indivisible in itself, although the multitude of things aspire to unite itself to it, and succeeds therein. If they aspire to possess it, they aspire to possess it entire, so that if they succeed in participating in that (being), they will participate in that entire (being) so far as their capacity reaches. Nevertheless, the things that participate in this (being) must participate in it as if they did not participate in it, in this sense that it does not belong exclusively to any of them. It is thus that this (being) dwells entirely in itself, and in the things in which it manifests; if it did not remain entire, it would no more be itself, and things would no longer participate in the (being) to which they aspire, but in some other (being) to which they did not aspire. [Ennead VI,4 (22) 8]

When a being participates in something, evidently it does not participate in itself; for thus it would really participate in nothing, and would remain what it was. The body that participates in something must, therefore, not participate in corporeal nature, for it possesses it already. Consequently, the body will not participate in the corporeal nature, any more than a magnitude would participate in a magnitude, which it possesses already. Let us even admit that a magnitude be increased, yet on that account alone it would not participate in magnitude; for a two-foot object does, not become a three-foot object, but the object which first had a certain quantity merely changes to some other quantity; otherwise two would become three. Thus, since that which has extension and is divided participates in genus that is different, and even very different, the thing in which it participates must neither be divided, nor have extension; but have absolutely no kind of quantity. Consequently, the (being) which everywhere is present entire must be present, though remaining indivisible. It is not indivisible merely because it is small, which would not make it any less divisible; only, it would no more be proportioned to the universe, it would not spread in the corporeal mass in the degree that it increases. Neither does it resemble a point, but it includes an infinity of points; consequently what you might suppose was a point would include an infinity of (separate) points, and could not be continuous, nor, consequently, proportion itself to the universe. If then every corporeal mass possess the (being) which is present everywhere, it must possess it entire in all the parts that compose it. [Ennead VI,4 (22) 13]

The purpose of the preceding considerations was to determine the meaning of the statement that intelligibles are actual; to decide whether every intelligible exist only actually, or whether it be only an actuality; and third, how even up there in the intelligible, where all things are actualities, there can also exist something potentially. If, then, in the intelligible world, there be no matter which might be called potential, if no being is to become something which it not yet is, nor transform itself, nor, while remaining what it is, beget something else, nor by altering, cause any substitution, then there could not be anything potential in this World of eternal essence outside of time. Let us now address the following question to those who admit the existence of matter, even in intelligible things: “How can we speak of matter in the intelligible world, if by virtue of this matter nothing exists potentially? For even if in the intelligible world matter existed otherwise than it does in the sense-world, still in every being would be the matter, the form and the compound which constitutes it.” They would answer that in intelligible things, what plays the part of matter is a form, and that the soul, by herself, is form; but, in relation to something else, is matter. Is the soul then potential in respect of this other thing? Hardly, for the soul possesses the form, and possesses it at present, without regard to the future, and she is divisible in form and matter only for reason; if she contain matter, it is only because thought conceives of her as double (by distinguishing form and matter in her). But these two things form a single nature, as Aristotle also says that his “quintessence” is immaterial. [Ennead V,5 (25) 3]

When dealing with numbers and geometrical figures, as well as with bodies, it is evident that the whole is necessarily diminished by its division into parts, and that each part is smaller than the whole. Rightly, these things should be susceptible to increase or diminution, as their nature is that of definite quantities, not quantity in itself. It is surely not in this sense that, when referring to the soul, we speak of quantities. The soul is not a quantity such as a “dozen,” which forms a whole divisible into unities; otherwise, we would end in a host of absurdities, since a group of ten is not a genuine unity. Either each one of the unities would have to be soul, or the Soul herself result from a sum of inanimate unities. [Ennead IV,3 (27) 2]

If the universal Soul be one in this manner, what about consequences of this (conception)? Might we not well doubt the possibility of the universal Soul’s simultaneously being one, yet present in all beings? How does it happen that some souls are in a body, while others are discarnate? It would seem more logical to admit that every soul is always in some body, especially the universal Soul. For it is not claimed, for the universal Soul, as it is for ours, that she ever abandons her body, and though it be by some asserted that the universal Soul may one day leave her body, it is never claimed that she would ever be outside of any body. Even admitting that some day she should be divided from all body, how does it happen that a soul could thus separate, while some other could not, if at bottom both are of the same nature? As to Intelligence, such a question would be impossible; the parts into which it is divided are not distinguished from each other by their individual difference, and they all exist together eternally, for Intelligence is not divisible. On the contrary, as the universal Soul is divisible within the bodies, as has been said, it is difficult to understand how all the souls proceed from the unitary (pure) Being. [Ennead IV,3 (27) 4]

How could the universal Soul simultaneously be the soul of yourself and of other persons? Might she be the soul of one person by her lower strata, and that of somebody else by her higher strata? To teach such a doctrine would be equivalent to asserting that the soul of Socrates would be alive while being in a certain body, while she would be annihilated (by losing herself within the universal Soul) at the very moment when (as a result of separation of the body) she had come into what was best (in the intelligible world). No, none of the true beings perishes. Not even the intelligences lose themselves up there (in the divine Intelligence), because they are not divided as are bodies, and each subsists in her own characteristics, to their differences joining that identity which constitutes “being.” Being located below the individual intelligences to which they are attached, individual souls are the “reasons” (born) of the intelligences, or more developed intelligences; from being but slightly manifold, they become very much so, while remaining in communion with the slightly manifold beings. As however they tend to introduce separation in these less divisible beings (that is, intelligences), and as nevertheless they cannot attain the last limits of division, they simultaneously preserve both their identity and difference. Each one remains single, and all together form a unity. [Ennead IV,3 (27) 5]

Must we consider that (in the soul), the indivisible and the divisible are identical, as if they were mingled together? Or should we consider the distinction between the indivisible and the divisible from some other point of view? Should the first be considered as the higher part of the soul, and the latter as the lower, just exactly as we say that one part of the soul is rational, and the other part is irrational? Such questions can be answered only by a close scrutiny of the nature of the divisibility and indivisibility of the soul. [Ennead IV,3 (27) 19]

When Plato says that the soul is indivisible, he speaks absolutely. When he insists that she is divisible, it is always relatively (to the body). He does indeed say that she becomes divisible in the bodies, but not that she has become such. Let us now examine how, by her nature, the body needs the soul to live, and what necessity there is for the soul to be present in the entire body. [Ennead IV,3 (27) 19]

By the mere fact that it feels by means of the entire body, every sense-power undergoes division. Since it is present everywhere, it may be said to be divided. But as, on the other hand, it manifests itself everywhere as a whole, it cannot really be considered as divided. We cannot go further than the statement that it becomes divisible in bodies. Some might object that it was divided only in the sense of touch. It is however also divided in the other senses, since it is always the same body that receives it, but only less so. The case is the same with the power of growth and nutrition; and if appetite have its seat in the liver, and anger in the heart, these appetites must be subject to the same conditions. Besides, it is possible that the body does not receive those appetites in a mixture, or that it receives them in some other manner, so that they result from some of the things that the body derives from the soul by participations. Reason and intelligence, however, are not communicated to the body because they stand in no need of any organs to fulfil their functions. On the contrary, they find in them only an obstacle to their operations. [Ennead IV,3 (27) 19]

Thus the indivisible and the divisible are in the soul two distinct parts, and not two things mingled together so as to constitute but a single one. They form a single whole composed of two parts, each of which is pure and separable from the other by its characteristic power. If then the part which in the body becomes divisible receives from the superior part the power of being indivisible, this same part might simultaneously be divisible and indivisible, as a mixture of divisible nature and of the (indivisible) power received by it from the higher part. [Ennead IV,3 (27) 19]

To begin with, it is unreasonable to insist that the notion of the subject one comes to us from the subject itself (which is one), from the visible man, for instance, or from some other animal, or even some stone. Evidently the visible man and the One are things entirely different, which could not be identified; otherwise, our judgment would not be able (as it is) to predicate unity of the non-man. Besides, as the judgment does not operate on emptiness for the right side, and other such things, seeing a difference of position when it tells us that an object is here, or there; likewise, it also sees something when it says that an object is one; for it does not experience there an affection that is vain, and it does not affirm unity without some foundation. It cannot be believed that the judgment says that an object is one because it sees that it is alone, and that there is no other; for, while saying that there is no other, the judgment implicitly asserts that the other is one. Further, the notions of “other” and “different” are notions posterior to that of unity; if the judgment did not rise to unity, it would not assert either the “other” nor the “different”; when it affirms that an object is alone, it says, “there is one only object”; and therefore predicates unity before “only.” Besides, the judgment which affirms is itself a substantial (being) before affirming unity of some other (being); and the (being) of which it speaks is one likewise before the judgment either asserts or conceives anything about it. Thus (being) must be one or many; if it be many, the one is necessarily anterior, since, when the judgment asserts that plurality is present, it evidently asserts that there is more than one; likewise, when it says that an army is a multitude, it conceives of the soldiers as arranged in one single corps. By this last example, it is plain that the judgment (in saying one body), does not let the multitude remain multitude, and that it thus reveals the existence of unity; for, whether by giving to the multitude a unity which it does not possess, or by rapidly revealing unity in the arrangement (which makes the body of the multitude), the judgment reduces multitude to unity. It does not err here about unity, any more than when it says of a building formed by a multitude of stones that it is a unity; for, besides, a building is more unified than an army. If, further, unity inhere in a still higher degree in that which is continuous, and in a degree still higher in what is not divisible, evidently that occurs only because the unity has a real nature, and possesses existence; for there is no greater or less in that which does not exist. [Ennead VI,6 (34) 13]

Neither Intelligence, nor the Soul that proceeds therefrom, are simple; both contain the universality of things with their infinite variety, so far as these are simple, meaning that they are not composite, but that they are principles and actualizations; for, in the intelligible world, the actualization of what occupies the last rank is simple; the actualization of what occupies the first rank is universal. Intelligence, in its uniform movement, always trends towards similar and identical things; nevertheless, each of them is identical and single, without being a part; it is on the contrary universal, because what, in the intelligible world, is a part, is not a simple unit, but a unity that is infinitely divisible. In this movement, Intelligence starts from one object, and goes to another object which is its goal. But does all that is intermediary resemble a straight line, or to a uniform and homogeneous body? There would be nothing remarkable about that; for if Intelligence did not contain differences, if no diversity awoke it to life, it would not be an actualization; its state would not differ from inactivity. If its movement were determined in a single manner, it would possess but a single kind of (restricted) life, instead of possessing the universal Life. Now it should contain an universal and omnipresent Life; consequently, it must move, or rather have been moved towards all (beings). If it were to move in a simple and uniform manner, it would possess but a single thing, would be identical with it, and no longer proceed towards anything different. If however it should move towards something different, it would have to become something different, and be two things. If these two things were then to be identical, Intelligence would still remain one, and there would be no progress left; if, on the contrary, these two things were to be different, it would be proceeding with this difference, and it would, by virtue of this difference joined to its divinity, beget some third thing. By its origin, the latter is simultaneously identical and different; not of some particular difference, but of all kinds of difference, because the identity it contains is itself universal. Thus being universal difference as well as universal identity, this thing possesses all that is said to be different; for its nature is to be universal differentiation (to spread over everything, to become everything else). If all these differences preceded this (Intelligence), the latter would be modified by them. If this be not the case, Intelligence must have begotten all the differences, or rather, be their universality. [Ennead VI,7 (38) 13]

How indeed could the One have become manifold, and how could it have begotten the species, if nothing but it existed? For it would not be manifold if there were not something to divide it, such as a size; now that which divides is other than that which is divided. The mere fact that it divides itself, or imparts itself to others, shows that it was already divisible before the division. [Ennead VI,2 (43) 2]

What is our relation with God? He hovers over the intelligible nature, and real being; while we, being on the third rank as counted from thence, are of the undivided universal Soul, which is indivisible because she forms part of the upper world, while she is divisible in regard to the bodies. She is indeed divisible in regard to the bodies, since she permeates each of them as far as they live; but at the same time she is indivisible because she is one in the universe. [Ennead I,1 (53) 8]
