(k.) (The body could not possess either sensation, thought, or virtue.) If the soul were a body, she would not possess either sensation, thought, science, virtue, nor any of the perfections that render her more beautiful. Here follows the proof. [Ennead IV,7 (2) 6]

Besides, if the principle that feels were corporeal, it could feel only so long as exterior objects produced in the blood or in the air some impression similar to that of a seal on wax. If they impressed their images on wet substances, as is no doubt supposed, these impressions would become confused as images in water, and memory would not occur. If, however, these impressions persisted, they would either form an obstacle to subsequent ones, and no further sensation would occur; or they would be effaced by the new ones, which would destroy memory. If then the soul is capable of recalling earlier sensations, and having new ones, to which the former would form no obstacle, it is because she is not corporeal. [Ennead IV,7 (2) 6]

The same reflections may be made about pain, and one’s feeling of it. When a man’s finger is said to give him pain, this, no doubt, is a recognition that the seat of the pain is in the finger, and that the feeling of pain is experienced by the directing principle. Consequently, when a part of the spirit suffers, this suffering is felt by the directing principle, and shared by the whole soul. How can this sympathy be explained? By relay transmission, (the Stoic) will answer; the sense-impression is felt first by the animal spirit that is in the finger, and then transmitted to the neighboring part, and so on till it reaches the directing part. Necessarily, if the pain is felt by the first part that experiences it, it will also be felt by the second part to which it is transmitted; then by the third, and so on, until the one pain would have caused an infinite number of sensations. Last the directing principle will perceive all these sensations, adding thereto its own sensation. Speaking strictly, however, each of these sensations will not transmit the suffering of the finger, but the suffering of one of the intermediate parts. For instance, the second sensation will relay the suffering of the hand. The third, that of the arm, and so on, until there will be an infinity of sensations. The directing principle, for its part, will not feel the pain of the finger, but its own; it will know none but that, it will pay no attention to the rest, because it will ignore the pain suffered by the finger. Therefore, relayed sensation is an impossibility, nor could one part of the body perceive the suffering felt by another part; for the body has extension, and, in every extension, parts are foreign to each other (the opposite of the opinion of Cleanthes, Nemesius). Consequently, the principle that feels must everywhere be identical with itself; and among all beings, the body is that which is least suitable to this identity. [Ennead IV,7 (2) 7]

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]

(9.) There are men who locate the soul in the body, so as to give her a foundation in some sphere of activity, to account for the various phenomena in the body, such as getting hot or cold, pushing on or stopping, (and the like). They evidently do not realize that bodies produce these effects only through incorporeal powers, and that those are not the powers that we attribute to the soul, which are thought, sensation, reasoning, desire, judiciousness, propriety and wisdom, all of them entities that cannot possible be attributes of a corporeal entity. Consequently, those (materialists) attribute to the body all the faculties of incorporeal essences, and leave nothing for the latter. [Ennead IV,7 (2) 8]

As there are two kinds of being (or, existence), one of sensation, and the other intelligible, it is preferable for the soul to live in the intelligible world; nevertheless, as a result of her nature, it is necessary for her also to participate in sense-affairs. Since she occupies only an intermediate rank, she must not feel wronged at not being the best of beings. Though on one hand her condition be divine, on the other she is located on the limits of the intelligible world, because of her affinity for sense-nature. She causes this nature to participate in her powers, and she even receives something therefrom, when, instead of managing the body without compromising her own security, she permits herself to be carried away by her own inclination to penetrate profoundly within it, ceasing her complete union with the universal Soul. Besides, the soul can rise above the body after having learned to feel how happy one is to dwell on high, by the experience of things seen and suffered here below, and after having appreciated the true Good by the comparison of contraries. Indeed the knowledge of the good becomes clearer by the experience of evil, especially among souls which are not strong enough to know evil before having experienced it. [Ennead IV,8 (6) 7]

Though I should set myself in opposition to popular views, I shall set down clearly what seems to me the true state of affairs. Not the whole soul enters into the body. By her higher part, she ever remains united to the intelligible world; as, by her lower part, she remains united to the sense-world. If this lower part dominates, or rather, if it be dominated (by sensation) and troubled, it hinders us from being conscious of what the higher part of the soul contemplates. Indeed that which is thought impinges on our consciousness only in case it descends to us, and is felt. In general, we are conscious of what goes on in every part of the soul only when it is felt by the entire soul. For instance, appetite, which is the actualization of lustful desire, is by us cognized only when we perceive it by the interior sense or by discursive reason, or by both simultaneously. Every soul has a lower part turned towards the body, and a higher part turned towards divine Intelligence. The universal Soul manages the universe by her lower part without any kind of trouble, because she governs her body not as we do by any reasoning, but by intelligence, and consequently in a manner entirely different from that adopted by art. The individual souls, each of whom administers a part of the universe, also have a part that rises above their body; but they are distracted from thought by sensation, and by a perception of a number of things which are contrary to nature, and which come to trouble them, and afflict them. Indeed, the body that they take care of constitutes but a part of the universe, is incomplete, and is surrounded by exterior objects. That is why it has so many needs, why it desires luxuriousness, and why it is deceived thereby. On the contrary, the higher part of the soul is insensible to the attraction of these transitory pleasures, and leads an undisturbed life. [Ennead IV,8 (6) 8]

If this (actualization begotten by the First, this external actualization) be all things, then that (One) is above all things, and consequently above being. If then (this external actualization) be all things, and be before all things, it does not occupy the same rank as the remainder (of all other things); and must, in this respect also, be superior to being, and consequently also to intelligence; for there is Something superior to intelligence. Essence is not, as you might say, dead; it is not devoid of life or thought; for intelligence and essence are identical. Intelligible entities do not exist before the intelligence that thinks them, as sense-objects exist before the sensation which perceives them. Intelligence itself is the things that it thinks, since their forms are not introduced to them from without. From where indeed would intelligence receive these forms? Intelligence exists with the intelligible things; intelligence is identical with them, is one with them. Reciprocally, intelligible entities do not exist without their matter (that is, Intelligence). [Ennead V,4 (7) 2]

Let us first consider if it may be affirmed that all souls form but one in the sense in which it is said that the soul of each individual is one. It seems absurd to pretend that my soul and yours form but one in this (numerical) sense; for then you would be feeling simultaneously with my feeling, and you would be virtuous when I was, and you would have the same desires as I, and not only would we both have the same sentiments, but even the identical sentiments of the universal (Soul), so that every sensation felt by me would have been felt by the entire universe. If in this manner all the souls form but one, why is one soul reasonable, and the other unreasonable, why is the one in an animal, and the other in a plant? On the other hand, if we do not admit that there is a single Soul, we will not be able to explain the unity of the universe, nor find a single principle for (human) souls. [Ennead IV,9 (8) 1]

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]

But why do not all the powers of the soul act everywhere? Now if we consider the Soul which is one everywhere, we find that sensation is not similar in all its parts (that is, in all the individual souls); that reason is not in all (but in certain souls exclusively); and that the vegetative power is granted to those beings who do not possess sensation, and that all these powers return to unity when they separate from the body. [Ennead IV,9 (8) 3]

If, however, the body derive its vegetative power from the Whole and from this (universal) Soul which is one, why should it not derive it also from our soul? Because that which is nourished by this power forms a part of the universe, which possesses sensation only at the price of “suffering.” As to the sense-power which rises as far as the judgment, and which is united to every intelligence, there was no need for it to form what had already been formed by the Whole, but it could have given its forms if these forms were not parts of the Whole which produces them. [Ennead IV,9 (8) 3]

Nevertheless a philosophical study of unity will follow the following course. Since it is Unity that we seek, since it is the principle of all things, the Good, the First that we consider, those who will wish to reach it must not withdraw from that which is of primary rank to decline to what occupies the last, but they must withdraw their souls from sense-objects, which occupy the last degree in the scale of existence, to those entities that occupy the first rank. Such a man will have to free himself from all evil, since he aspires to rise to the Good. He will rise to the principle that he possesses within himself. From the manifold that he was he will again become one. Only under these conditions will he contemplate the supreme principle, Unity. Thus having become intelligence, having trusted his soul to intelligence, educating and establishing her therein, so that with vigilant attention she may grasp all that intelligence sees, he will, by intelligence, contemplate unity, without the use of any senses, without mingling any of their perceptions with the flashes of intelligence. He will contemplate the purest Principle, through the highest degree of the purest Intelligence. So when a man applies himself to the contemplation of such a principle and represents it to himself as a magnitude, or a figure, or even a form, it is not his intelligence that guides him in this contemplation for intelligence is not destined to see such things; it is sensation, or opinion, the associate of sensation, which is active in him. Intelligence is only capable of informing us about things within its sphere. [Ennead VI,9 (9) 3]

Besides everything that is a mass or a magnitude could not occupy the first rank in nature; those gross objects which are by sensation considered beings must be ranked as inferior. In seeds, it is not the moist element that should be valued, but the invisible principle, number, and the (seminal) reason. Number and “pair” are only names for the reasons (ideas) and intelligence. The “pair” is indeterminate so far as it plays the part of substrate (in respect to unity). The number that is derived from the pair, and the one, constitute every kind of form, so that Intelligence has a shape which is determined by the ideas begotten within it. Its shape is derived in one respect from the one, and in another respect, from itself, just like actualized sight. Thought, indeed, is actualized sight, and both these entities (the faculty and the actualization) form but one. [Ennead V,1 (10) 5]

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]

Nor does the universal Soul remain at rest, but enters in motion to beget an image of herself. On the one hand, it is by contemplation of the principle from which she proceeds that she achieves fulness; on the other hand, it is by advancing on a path different from, and opposed to (the contemplation of Intelligence), that she begets an image of herself, sensation, and the nature of growth. Nevertheless, nothing is detached or separated from the superior principle which begets her. Thus the human soul seems to reach down to within that of (plant) growth. She descends therein inasmuch as the plant derives growth from her. Nevertheless it is not the whole soul that passes into the plant. Her presence there is limited to her descent towards the lower region, and in so far as she produces another hypostatic substance, by virtue of her procession, which occurs by her condescension to care for the things below her. But the higher part of the Soul, that which depends on Intelligence, allows the Intelligence to remain within itself…. [Ennead V,2 (11) 1]

We may say that there is a procession from the First to the last; and in this procession each occupies its proper place. The begotten (being) is subordinated to the begetting (being). On the other hand, it becomes similar to the thing to which it attaches, so long as it remains attached thereto. When the soul passes into the plant, there is one of her parts that unites thereto (the power of growth); but besides, it is only the most audacious and the most senseless part of her that descends so low. When the soul passes into the brute, it is because she is drawn thereto by the predominance of the power of sensation. When she passes into man, it is because she is led to do so by the exercise of discursive reason, either by the movement by which she proceeds from Intelligence, because the soul has a characteristic intellectual power, and consequently has the power to determine herself to think, and in general, to act. [Ennead V,2 (11) 2]

(An objector might ask) whether there be identity of conditions between the soul’s not thinking, and her experience while thinking of matter? By no means; when the soul is not thinking of anything, she neither asserts anything, nor experiences anything. When she thinks of matter, she experiences something, she receives the impression of the shapeless. When she presents to herself objects that possess shape and magnitude, she conceives of them as composite; for she sees them as distinct (or, colored?) and determined by qualities they contain. She conceives of both the totality and its two constituent elements. She also has a clear perception, a vivid sensation of properties inherent (in matter). On the contrary, the soul receives only an obscure perception of the shapeless subject, for there is no form there. Therefore, when the soul considers matter in general, in the composite, with the qualities inherent in this composite, she separates them, analyzes them, and what is left (after this analysis), the soul perceives it vaguely, and obscurely, because it is something vague and obscure; she thinks it, without really thinking it. On the other hand, as matter does not remain shapeless, as it is always shaped, within objects, the soul always imposes on matter the form of things, because only with difficulty does she support the indeterminate, since she seems to fear to fall out of the order of beings, and to remain long in nonentity. [Ennead II,4 (12) 10]

One more subject remains to be considered. The lowest power of the universal Soul (the inferior soul), rests on the earth, and thence radiates abroad throughout the universe. The (higher, or celestial) power (of the world-Soul) which, by nature, possesses sensation, opinion, and reasoning, resides in the celestial spheres, whence it dominates the inferior power, and communicates life to it. It thereby moves the inferior power, embracing it in a circle; and it presides over the universe as it returns (from the earth) to the celestial spheres. The inferior power, being circularly embraced by the superior power, reflects upon itself, and thus operates on itself a conversion by which it imparts a movement of rotation to the body within which it reacts. (This is how motion starts) in a sphere that is at rest: as soon as a part moves, the movement spreads to the rest of it, and the sphere begins to revolve. Not otherwise is our body; when our soul begins to move, as in joy, or in the expectation of welfare, although this movement be of a kind very different from that natural to a body, this soul-movement produces local motion in the body. Likewise the universal Soul, on high, while approaching the Good, and becoming more sensitive (to its proximity), thereby impresses the body with the motion proper to it, namely, the local movement. (Our own human) sense-(faculty), while receiving its good from above, and while enjoying the pleasures proper to its nature, pursues the Good, and, inasmuch as the Good is everywhere present, it is borne everywhere. The intelligence is moved likewise; it is simultaneously at rest and in motion, reflecting upon itself. Similarly the universe moves in a circle, though simultaneously standing still. [Ennead II,2 (14) 3]

Other principles remain unmoved while producing and exhibiting their (“hypostases,” substantial acts, or) forms of existence. The (universal) Soul, however, is in motion while producing and exhibiting her (“substantial act,” or) forms of existence, namely, the functions of sensation and growth, reaching down as far as (the sphere of the) plants. In us also does the Soul function, but she does not dominate us, constituting only a part of our nature. She does, however, dominate in plants, having as it were remained alone there. Beyond that sphere, however, nature begets nothing; for beyond it exists no life, begotten (matter) being lifeless. All that was begotten prior to this was shapeless, and achieved form only by trending towards its begetting principle, as to its source of life. Consequently, that which is begotten cannot be a form of the Soul, being lifeless, but must be absolute in determination. The things anterior (to matter, namely, the sense-power and nature), are doubtless indeterminate, but only so within their form; the are not absolutely indeterminate; they are indeterminate only in respect of their perfection. On the contrary, that which exists at present, namely, (matter), is absolutely indeterminate. When it achieves perfection, it becomes body, on receiving the form suited to its power. This (form) is the receptacle of the principle which has begotten it, and which nourishes it. It is the only trace of the higher things in the body, which occupies the last rank amidst the things below. [Ennead III,4 (15) 3]

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]

Shall we have recourse to the (Stoic) “continuity of parts” to explain the sympathy which interrelates all the organs? This hypothesis, however, is useless, unless this continuity eventuate in unity. For we cannot admit, as do certain (Stoic) philosophers, who deceive themselves, that sensations focus in the “predominating principle” by “relayed transmission.” To begin with, it is a wild venture to predicate a “predominating principle” of the soul. How indeed could we divide the soul and distinguish several parts therein? By what superiority, quantity or quality are we going to distinguish the “predominating part” in a single continuous mass? Further, under this hypothesis, we may ask, Who is going to feel? Will it be the “predominating part” exclusively, or the other parts with it? If that part exclusively, it will feel only so long as the received impression will have been transmitted to itself, in its particular residence; but if the impression impinge on some other part of the soul, which happens to be incapable of sensation, this part will not be able to transmit the impression to the (predominating) part that directs, and sensation will not occur. Granting further that the impression does reach the predominating part itself, it might be received in a twofold manner; either by one of its (subdivided) parts, which, having perceived the sensation, will not trouble the other parts to feel it, which would be useless; or, by several parts simultaneously, and then we will have manifold, or even infinite sensations which will all differ from each other. For instance, the one might say, “It is I who first received the impression”; the other one might say, “I received the impression first received by another”; while each, except the first, will be in ignorance of the location of the impression; or again, each part will make a mistake, thinking that the impression occurred where itself is. Besides, if every part of the soul can feel as well as the predominating part, why at all speak of a “predominating part?” What need is there for the sensation to reach through to it? How indeed would the soul recognize as an unity the result of multiple sensations; for instance, of such as come from the ears or eyes? [Ennead IV,2 (21) 2]

Whence originates extension in our universe, and in the animals? The world of life contains no extension. Sensation, whose testimony hinders us from believing what we are told in this respect, reveals to us here and there the world of life. But reason tells us that, if we see it thus, it is not that it is really extended here and there, but that all that possesses extension has participated in the world of life, which, however, has no extension. [Ennead VI,4 (22) 13]

How could that part of the soul that is superior to sensation and passion remain unalterable, while admitting vice, false opinions, and ignorance (or folly); when it has desires or aversions; when it yields itself to joy or pain, to hate, jealousy, and appetite; when, in one word, it never remains calm, but when all the things that happen to it agitate it, and produce changes within it? [Ennead III,6 (26) 1]

There are desires and aversions in the soul, which demand consideration. It is impossible to deny that pain, anger, joy, appetite and fear are changes and affections which occur in the soul, and that move her. We must here draw a distinction, for it would be denying the evidence to insist that there are in us no changes or perception of these changes. We cannot attribute them to the soul, which would amount to the admission that she blushes, or grows pale, without reflecting that these “passions,” though produced by the soul, occur in a different substance. For the soul, shame consists in the opinion that something is improper; and, as the soul contains the body, or, to speak more exactly, as the body is a dependency of the animating soul, the blood, which is very mobile, rushes to the face. Likewise, the principle of fear is in the soul; paleness occurs in the body because the blood concentrates within the interior parts. In joy, the noticeable dilation belongs to the body also; what the body feels is not a “passion.” Likewise with pain and appetite; their principle is in the soul, where it remains in a latent condition; what proceeds therefrom is perceived by sensation. When we call desires, opinions and reasonings “movements of the soul,” we do not mean that the soul becomes excited in the production of these movements, but that they originate within her. When we call life a movement, we do not by this word mean an alteration; for to act according to one’s nature is the simple and indivisible life of each part of the soul. [Ennead III,6 (26) 3]

Such are the objections that may be raised against those who consider all beings as corporeal; who wish to judge of their existence only by impressions they receive therefrom, and who try to found the certitude of truth on the images of sensation. They resemble sleeping men who take as realities the visions they have in their dreams. Sensation is the dream of the soul; so long as the soul is in the body, she dreams; the real awakening of the soul consists in genuine separation from the body, and not in rising along with the body. To rise with the body is to pass from one sleep into another kind; from one bed to another; really to awake is to separate oneself completely from the body. The body, whose nature is contrary to that of the soul, consequently has a nature contrary to that of “being.” This is proved by the generation, flux, and decay of bodies, all processes contrary to the nature of “being.” [Ennead III,6 (26) 6]

The objects that concentrate the rays of the sun, are themselves visible, by receiving from the fire of sensation what takes fire in their hearth. They appear because the images that form themselves are around and near them, and touch each other, and finally because there are two limits in these objects. But when the (“seminal) reason” is in matter, it remains exterior to matter in an entirely different manner; it has a different nature. Here it is not necessary that there be two limits; matter and reason are strangers to each other by difference of nature, and by the difference between their natures that makes any mixture of them impossible. The cause that each remains in itself is that what enters into matter does not possess it, any more than matter possesses what enters into it. That is how opinion and imagination do not mingle in our soul, and each remains what it was, without entailing or leaving anything, because no mingling can occur. These powers are foreign to each other, not in that there is a mere juxtaposition, but because between them obtains a difference that is grasped by reason, instead of being seen by sight. Here imagination is a kind of phantom, though the soul herself be no phantom, and though she seem to accomplish, and though she really accomplish many deeds as she desires to accomplish them. [Ennead III,6 (26) 15]

This is the better illustration: the soul is present in the body as light is present in air. Light is indeed present in air without being present to it; that is, light is present to the whole air without mingling with it, and light remains within itself while the air escapes. When the air, within which light radiates, withdraws from the light, the air keeps none of the light; but it is illuminated so long as the air remains subject to the action of light. Air, therefore, is in light, rather than light is in air. While explaining the generation of the universe, therefore, Plato properly locates the body (of the world) in the soul, and not the soul in the body. He also states that there is a part of the soul that contains the body, and another in which there is no body, in this sense, that there are soul-powers of which the body has no need. The case is similar with the other souls. Their powers in general are not present to bodies, and only those powers of which the body stands in need are present to it. These however are present to the body without being built up either on the members, or upon the body as a whole. For sensation, the faculty of feeling is entirely present to the whole organ which is feeling (as, for instance, to the whole brain); likewise for the other functions, the different faculties are each present to a different organ. I shall explain myself. [Ennead IV,3 (27) 22]

Since, for the body, being animated amounts to being penetrated by the light shed by the soul, every part of the body participates therein in some particular manner. Each organ, according to its fitness, receives the power suitable to the function it fulfils. Thus we may say that the power of sight resides in the eyes; that of hearing in the ears; that of taste in the tongue; that of smell in the nose; that of touch in the whole body, since, for the latter sense, the whole body is the organ of the soul. Now as the instruments for touch are the first nerves, which also possess the power of moving the organism, as they are the seat of this power; as, besides, the nerves originate in the brain, in the brain has been localized the principle of sensation and appetite — in short, the principle of the whole organism; no doubt because it was thought that the power which uses the organs is present in that part of the body where are the origins of these organs. It would have been better to say that it is the action of the power that makes use of the organs that originates in the brain; for that part of the body from which starts the movement impressed on the organ had to serve somewhat as a foundation for the power of the workman, a power whose nature is in harmony with that of the organ (it sets in motion); or rather, this part of the body does not serve as foundation for this power, for this power is everywhere, but the principle of the action is in that part of the body in which is the very principle of that organ. [Ennead IV,3 (27) 23]

On the other hand, as the power of sensation and the power of appetite, which belong to the sensible and imaginative soul, are beneath reason, because they are related to what is inferior, while reason is above, the result was that the ancients localized reason in the highest part of the animal, in the head; not that reason is in the brain, but because reason is seated in the sense-power, by the intermediation of which, only, reason may be said to reside in the brain. The sense-power, surely, had to be attributed to the body, and, within the body, to the organs most capable of lending themselves to its action. Reason, which has no (direct) dealing with the body, had however to be in relation with the sense-power, which is a form of the soul, and can participate in reason. The sense-power, does, to a certain extent, judge; and the power of imagination has something intellectual. Last, the appetite, and the desire somehow connect with imagination and reason. Reason, therefore, is in the head, not as in a locality, but because it is in relation with the sense-power which resides in that organ, as has been shown above. [Ennead IV,3 (27) 23]

If the two elements which compose the animal share in the act of sensation, the sensation is common to the soul and the body, such as the acts of piercing or weaving. Thus, in sensation, the soul plays the part of the workman, and the body that of his tool; the body undergoes the experience, and serves as messenger to the soul; the soul perceives the impression produced in the body, or by the body; or she forms a judgment about the experience she has undergone. Consequently sensation is an operation common to the soulsoul and body. [Ennead IV,3 (27) 26]

This could not be the state of affairs with memory, by which the soul, having already through sensation perceived the impression produced in the body, preserves it, or dismisses it. It might be claimed that memory also is common to the soulsoul and body, because its efficiency depends on the adjustments of the bodies. No doubt the body can hinder or promote the exercise of memory, without this faculty ceasing to be peculiar to the soul. How shall we try to prove that the memory of knowledge acquired by study, belongs to the compound, and not to the soul alone? If the organism be the composite of soul and body, in the sense that it is some third object begotten by their union, it will be absurd to say that it is neither soul nor body. Indeed, it could not be anything different from the soul and body, neither if the soul and body were transformed into the composite of which they are the elements, nor if they formed a mixture, so that the soul would be no more than potentially in the organism. Even in this case, it is still the soul, and the soul alone, that would remember. Thus in a mixture of honey and wine, it is the honey alone that should be credited with any sweetness that may be tasted. [Ennead IV,3 (27) 26]

Does memory belong to the powers by which we feel and know? Is it by appetite that we remember the things that excite our desires, and by anger that we remember the things that irritate us? Some will think so. It is indeed the same faculty which feels pleasure, and retains remembrance thereof. Thus when, for instance, appetite meets an object which has already made it experience pleasure, it remembers this pleasure on seeing this object. Why indeed should appetite not be similarly moved by some other object? Why is it not moved in some manner by the same object? Why should we not thus attribute to it the sensation of things of this kind? Further, why should appetite itself not be reduced to the power of sensation, and not do likewise for everything, naming each thing, by what predominates therein? [Ennead IV,3 (27) 28]

Must we attribute sensation to each power, but in a different manner? In this case, for instance, it will be sight, and not appetite, which will perceive sense-objects; but appetite will be later wakened by sensation which will be “relayed,” (as the Stoics would say); and though it does not judge of sensation, it will unconsciously feel the characteristic affection. The same state of affairs will obtain with anger. It will be sight which will show us an injustice, but it will be anger which will resent it. Just so, when a shepherd notices a wolf near his flock, the dog, though he have not yet observed anything, will be excited by the smell or noise of the wolf. It certainly is appetite which experiences pleasure, and which keeps a trace of it; but this trace constitutes an affection or disposition, and not a memory. It is another power which observes the enjoyment of pleasure, and which remembers what occurred. This is proved by the fact that memory is often ignorant of the things in which appetite has participated, though appetite still preserve traces thereof. [Ennead IV,3 (27) 28]

Are we compelled to remember sensations by sensibility, whether it be the same power which feels sensation, and which remembers sensation, or is it also discursive reason which conceives and remembers conceptions. But the men who reason the best are not those who also remember the best; and those who have equally delicate senses, do not all, on that account, have an equally good memory. On the contrary, some have delicate senses, while others have a good memory, without however being capable of perceiving equally well. On the other hand, if feeling and remembering be mutually independent, there will be (outside of sensibility) another power which will remember things formerly perceived by sensation, and this power will have to feel what it is to remember. [Ennead IV,3 (27) 29]

(To solve all these difficulties) it may be stated that nothing hinders the admission that the actualization of the sensation produces in memory an image, and that the imagination, which differs (from sensation), possesses the power of preserving and recalling these images. It is indeed imagination in which sensation culminates; and when sensation ceases, imagination preserves its representation. If then this power preserve the image of the absent object, it constitutes memory. According as the image remains for a longer or shorter time, memory is or is not faithful; and our memories last, or are effaced. Memory of sense-objects therefore belongs to the imagination. If this faculty of memory be possessed by different persons in unequal degrees, this difference depends either on the difference of forces, or on practice (or exercise), or on the absence or presence of certain bodily dispositions which may or may not influence memory, or disturb it. But elsewhere we shall study the question further. [Ennead IV,3 (27) 29]

Indeed, as the whole soul feels, she localizes the passion in the organ which has received the blow, and which suffers. If she herself experienced the suffering, as the whole of her is present in the whole body, she could not localize the suffering in one organ; the whole of her would feel the suffering; she would not relate it to any one part of the body, but to all in general: for she is present everywhere in the body. The finger suffers, and the man feels this suffering, because it is his finger. It is generally said that the man suffers in his finger, just as it is said that he is blond, because his eyes are blue. It is therefore the same entity that undergoes passion’ and suffering, unless the word “suffering’ should not here designate both the passion, and the sensation which follows it; in this case no more is meant than that the state of suffering is accompanied by sensation. The sensation itself is not the suffering, but the knowledge of the suffering. The potentiality which knows must be impassible to know well, and well to indicate what is perceived. For if the faculty which is to indicate the passions itself suffer, it will either not indicate them, or it will indicate them badly. [Ennead IV,4 (28) 19]

Consequently, it may be said that the origin of the desires should be located in the common (combination) and in the physical nature. To desire and seek something would not be characteristic of a body in any state whatever (which would not be alive). On the other hand, it is not the soul which seeks after sweet or bitter flavors, but the body. Now the body, by the very fact that it is not simply a body (that it is a living body), moves much more than the soul, and is obliged to seek out a thousand objects to satisfy its needs: at times it needs sweet flavors, at others, bitter flavors; again humidity, and later, heat; all of them being things about which it would not care, were it alone. As the suffering is accompanied by knowledge, the soul, to avoid the object which causes the suffering, makes an effort which constitutes flight, because she perceives the passion experienced by the organ, that contracts to escape the harmful object. Thus everything that occurs in the body is known by sensation, and by that part of the soul called nature, and which gives the body a trace of the soul. On one hand, desire, which has its origin in the body, and reaches its highest degree in nature, attaches itself thereto. On the other hand, sensation begets imagination, as a consequence of which the soul satisfies her need, or abstains, and restrains herself; without listening to the body which gave birth to desire, nor the faculty which later felt its reaction. [Ennead IV,4 (28) 20]

Let us now examine to what beings sensation belongs, and whereby it operates. Let us see whether sensation can take place even without organs. Of what use to the earth could sensation be? For it does not serve the earth as means of knowledge; the knowledge which consists in wisdom suffices for the beings to whom sensation is of no use. This consideration might however be denied, for the knowledge of sense-objects offers, besides utility, some of the charms of the Muses. Such is, for example, the knowledge of the sun and the other stars, whose contemplation itself is agreeable. This problem will therefore demand solution. [Ennead IV,4 (28) 22]

We must therefore first investigate if the earth possess senses, to what animals sensation naturally belongs, and how sensation operates. It will be necessary to begin by discussing the doubtful points that we have indicated, and to examine in general if sensation can operate without organs, and if the senses have been given for utility, admitting even that they can procure some other advantage. [Ennead IV,4 (28) 22]

The soul and the exterior object do not therefore suffice (to explain sensation); for there would be nothing that suffers. There must therefore be a third term that suffers, that is, which receives the sense-form, or, shape. This third term must “sympathize,” or, share the passion of the exterior object, it must also experience the same passion, and it must be of the same matter; and, on the other hand, its passion must be known by another principle; last, passion must keep something of the object which produces it, without however being identical with it. The organ which suffers must therefore be of a nature intermediary between the object which produces the passion and the soul, between the sensible and the intelligible, and thus play the part of a term intermediary between the two extremes, being receptive on one side, making announcements on the other, and becoming equally similar to both. The organ that is to become the instrument of knowledge must be identical neither with the subject that knows, nor with the object that is known. It must become similar to both of them; to the exterior object because it suffers, and to the cognizing soul because the passion which it experiences becomes a form. Speaking more accurately, the sensations operate by the organs. This results from the principle asserted above, that the soul isolated from the body can grasp nothing in the sense-world. As used here, the word “organ” either refers to the whole body, or to some part of the body fitted to fulfil some particular function; as in the case of touch or sight. Likewise, it is easy to see that tools of artisans play a part intermediary between the mind which judges, and the object which is judged; and that they serve to discover the properties of substances. For instance, a (foot) rule, which is equally conformed to the idea of straightness in the mind, and to the property of straightness in the wood, serves the artisan’s mind as intermediary to judge if the wood he works be straight. [Ennead IV,4 (28) 23]

We have just demonstrated that sensation belongs exclusively to an embodied soul, and that this implies organs. But we have nothing to do with the question whether the perceived object must be in contact with the organ, or whether the sensation can take place at a distance from the sense-object, by means of an intermediary; as the case of the fire which is located at a distance from our body, without the intermediary’s suffering in any manner. It happens again where, empty space serving as intermediary between the eye and the color, one may well ask whether, to see, it suffice to possess the potentiality proper to that organ. But it is sure that sensation is some activity of the soul in a body, or through a body. [Ennead IV,4 (28) 23]

Whether the senses were given us for the sake of utility must be examined as follows. If the soul were separated from the body, she would not feel; she feels only when united to a body; therefore she feels by and for the body. It is from the soul’s intimacy with the body that sensation results, either because all passions, when keen enough, reach the soul; or whether the senses were made for us to take care that no object approaches too near us, or exercises on our organs an action strong enough to destroy them. If so, the senses were given us for the sake of utility. Even if the senses do serve to acquire knowledge and information, they would be of no use to a being who possesses knowledge, but only to one who needs to learn he has the misfortune of being ignorant, or who needs to remember, because he is subject to forgetfulness. They are therefore not found in the being who has no need to learn, and who does not forget. [Ennead IV,4 (28) 24]

Let us consider what consequences may be drawn therefrom for the earth, the stars, and especially for the heavens and the whole world. From what we have seen, the parts of the world which suffer may possess sensation in their relation with other parts. But is the entire world, capable of feeling, as it is entirely impassible in its relations with itself? If sensation demand on one hand an organ, and on the other the sense-object, the world which includes everything, can have neither organ to perceive, nor exterior object to be perceived. We may therefore ascribe to the world a sort of intimate sensation, such as we ourselves possess, and deny to it the perception of other objects. When we feel something unusual in our bodies, we perceive it as being external. Now as we perceive not only exterior objects, but even some part of our body through some other part of the body itself, similarly the world might very well perceive the sphere of the planets by means of the sphere of the fixed stars; and perceive the earth with all the objects it contains by means of the sphere of the planets? If these beings (the stars and the planets) do not feel the passions felt by other beings, why might they not also possess different senses? Might not the sphere of the planets not only by itself possess sight by itself, but in addition be the eye destined to transmit what it sees to the universal Soul? Since she is luminous and animated, she might see as does an eye, supposing that she did not feel the other passions. (Plato), however, said, “that the heavens have no need of eyes.” Doubtless the heavens have nothing outside of themselves to see; and consequently, they may not have need of eyes, as we have; but they contain something to contemplate, namely, themselves. If it should be objected that it is useless for them to see themselves, it may be answered that they were not made principally for this purpose, and that if they see themselves, it is only a necessary consequence of their natural constitution. Nothing therefore hinders them from seeing, as their body is diaphanous. [Ennead IV,4 (28) 24]

It would seem that in order to see, and in general to feel, mere possession of the necessary organs by the soul, is not enough; the soul must also be disposed to direct her attention to things of sense. But it is usual for the (universal) Soul to be ever applied to the contemplation of intelligible things; and mere possession of the faculty of sensation would not necessarily imply its exercise, because it would be entirely devoted to objects of a higher nature. So when we apply ourselves to the contemplation of intelligible things, we notice neither the sensation of sight, nor those of other senses; and, in general, the attention that we give to one thing hinders us from seeing the others. Even among us human beings, to wish to perceive one of our members through another, as, for instance, looking at ourselves, is both superfluous and vain, unless this has some very good purpose. Moreover, it is a characteristic of an imperfect and fallible being to contemplate some external thing, merely because it is beautiful. It may therefore well be said that if to feel, hear and taste are distractions of a soul that attaches herself to outer objects, the sun and the other stars cannot see or hear, except accidentally. It would however not be unreasonable to admit that they turn towards us through the exercise of the senses of sight or hearing. Now, if they turn towards us, they must be mindful of human affairs. It would be absurd that they should not remember the men to whom they do so much good; how indeed would they do good, if they had no memory? [Ennead IV,4 (28) 25]

The stars know our desires through the agreement and sympathy established between them and us by the harmony reigning in the universe. Our desires are granted by the same method. Likewise, magic is founded on the harmony of the universe; it acts by means of the forces which are interconnected by sympathy. If so, why should we not attribute to the earth the faculty of sensation? Granting this, what sort of sensations would we attribute to it? To begin with, why should we not attribute to it touch, whether by one part feeling the condition of another, and by the transmission of the sensation to the governing power, or by the whole earth feeling the fire, and other similar things; for if the terrestrial element is inert, it certainly is not insensible. The earth will therefore feel the great things, and not those of minor importance. Why should it feel? Surely if the earth have a soul, she will not ignore the strongest motions therein. The earth must also be supposed to feel, in order to dispose all that depends on her for the benefit of humanity. All these things she will suitably dispose by the laws of harmony. She can hear and grant the prayers addressed to her, but in a manner other than we ourselves would do. Besides, she might exercise other senses in her relations, either with herself, or with foreign things; as, for example, to have the sensations of taste and smell perceived by other beings. Perhaps even she has need to perceive the odors of the liquids to fulfil her providential functions in respect to animals, and to take care of her own body. [Ennead IV,4 (28) 26]

If the earth communicate to plant-life the power of begetting and growing, it possesses this power within itself, and gives only a trace of it to the plants which derive from it all their fruitfulness, and as it were are the living flesh of its body. It gives to them what is best in them; this can be seen in the difference between a plant growing in the soil, and of a branch cut from it; the former is a real plant, the latter is only a piece of wood. What is communicated to the body of the earth by the Soul which presides over it? To see this it is sufficient to notice the difference between some earth resting within the soil, and a piece that is detached therefrom. It is likewise easy to recognize that stones increase in size as long as they are in the bosom of the earth, while they remain in the same state when they have been plucked out therefrom. Everything therefore bears within itself a trace of the universal vegetative (power) shed abroad over the whole earth, and belonging particularly to no one of its parts. As to the earth’s power of sensation, it is not (like its vegetative power) mingled with the body of the earth; it only hovers above and guides it. Moreover, the earth possesses also, higher than the above powers, a soul and an intelligence. They bear respectively the names of Ceres and Vesta, according to the revelations of men of prophetic nature, who allow themselves to be inspired by the divine. [Ennead IV,4 (28) 27]

First, what is the nature of anger? We grow irritated at maltreatment of ourselves or of a person dear to us; in general, when we witness some outrage. Therefore anger implies a certain degree of sensation, or even intelligence, and we should have to suppose that anger originates in some principle other than the vegetative power. Certain bodily conditions, however, predispose us to anger; such as being of a fiery disposition, and being bilious; for people are far less disposed to anger if of a cold-blooded nature. Besides, animals grow irritated especially by the excitement of this particular part, and by threats of harm to their bodily condition. Consequently we would once more be led to refer anger to the condition of the body and to the principle which presides over the constitution of organism. Since men are more irritable when sick than when well, when they are hungry, more than when well satisfied, anger or its principle should evidently be referred to the organized and living body; evidently, attacks of anger are excited by the blood or the bile, which are living parts of the animal. As soon as the body suffers, the blood as well as the bile boils, and there arises a sensation which arouses the imagination; the latter then instructs the soul of the state of the organism, and disposes the soul to attack what causes this suffering. On the other hand, when the reasonable soul judges that we have been injured, she grows excited, even if there were no disposition to anger in the body. This affection seems therefore to have been given to us by nature to make us, according to the dictates of our reasons, repel and threatens us. (There are then two possible states of affairs.) Either the irascible power first is moved in us without the aid of reason, and later communicates its disposition to reason by means of the imagination; or, reason first enters into action, and then reason communicates its impulse to that part of our being which is disposed to anger. In either case, anger arises in the vegetative and generative power, which, in organizing the body, has rendered it capable to seek out what is agreeable, and to avoid what is painful; diffusing the bitter bile through the organism, imparting to it a trace of the soul, thus communicating to it the faculty of growing irritated in the presence of harmful objects, and, after having been harmed, of harming other things, and to render them similar to itself. Anger is a trace of the soul, of the same nature as the soul’s faculty of desire, because those least seek objects agreeable to the body, and who even scorn the body, are least likely to abandon themselves to the blind transports of anger. Although plant-life possesses the vegetative power, it does not possess the faculty of anger because it has neither blood nor bile. These are the two things which, in the absence of sensation, leads one to boil with indignation. When however sensation joins these two elements, there arises an impulse to fight against the harmful object. If the irrational part of the soul were to be divided into the faculty of desire, and that of anger, and if the former were to be considered the vegetative power, and the other, on the contrary, as a trace of the vegetative power, residing in either the heart or blood, or in both; this division would not consist of opposed members, because the second would proceed from the first. But there is an alternative: both members of this division, the faculties of desire and anger, might be considered two powers derived from one and the same principle (the vegetative power). Indeed, when the appetites are divided, it is their nature, and not the being from which they depend, that is considered. This essence itself, however, is not the appetite, but completes it, harmonizing with it the actions proceeding from the appetite. It is also reasonable to assign the heart as seat of the trace of the soul which constitutes anger; for the heart is not the seat of the soul, but the source of the (arterially) circulating blood. [Ennead IV,4 (28) 28]

If these images do not reach us by some sort of effluence, why should the air be affected, and why should we ourselves be affected only as a result of the affection experienced by the air? If we felt only because the air had been affected before us, we would attribute the sensation of sight not to the visible object, but to the air located near us, as occurs with heat. In the latter case it is not the distant fire, but the air located near us which, being heated, then warms us; for the sensation of heat presupposes contact, which does not occur with vision. We see, not because the sense-object is imposed on the eye (but because the medium is illuminated); now it is necessary for the medium to be illuminated because the air by itself is dark. If the air were not dark, it would have no need of light; for (to effectuate vision) the obscurity, which forms an obstacle to vision, must be overcome by light. That is perhaps the reason why an object placed very near the eye is not seen; for it brings with it the darkness of the air, together with its own. [Ennead IV,5 (29) 2]

It might indeed be objected that without medium, vision ceases. This occurs not because of the lack of medium, but because the sympathy of the (universal) organism is in such a case destroyed since a medium presupposes that all the parts of this organism together form but a single being. It would indeed seem to be a general condition necessary for sensation that the universal organism be sympathetic with itself; otherwise, no one thing could participate in the power of any other thing that might happen to be very distant. [Ennead IV,5 (29) 3]

Every organism is coherent (that is, is sympathetic with itself). In the case of a single organism, our demonstration suffices, and all things will experience common affections so far as they constitute parts of the single organism. The plea that a body exterior to the world could be felt because of its resemblance is ill-founded because perception is characteristic of an organism and because it is the organism that possesses perception. For its organ resembles (the perceived object); thus sensation would be the perception presented to the soul by means of organs similar to the perceived objects. If then the organism feel not only its contents, but also objects resembling them, it will perceive these things by virtue of its organic nature; and these things will be perceived not because they are contents thereof, but by virtue of their resemblance thereto. It seems rather that perceived objects must be perceived in the measure of their resemblance, because the soul has familiarized herself with them, and has assimilated them to herself. If then the soul which has assimilated these objects to herself differ from them, the things which were supposed to have become assimilated to her will remain entirely foreign to her. The absurdity of this consequence shows us that there is a flaw in the hypothesis; for it affirms simultaneously that the soul exists, and does not exist, that the things are both conformable and different, similar and dissimilar. Since then this hypothesis implies contradictories, it is not admissible; for it supposes that the soul exists in this world, as a result of the world, both being and not being universal, both being and not being different, both being and not being perfect. The above hypothesis must therefore be abandoned; and since it implies a contradiction, no reasonable consequence could be deduced therefrom. [Ennead IV,5 (29) 8]

These words signify that nature is a soul begotten by a superior Soul that possesses a more potent life, and contains her contemplation silently within herself, without inclining towards that which is higher or lower. Abiding within her own essence (“being”) that is, within her own rest and self-consciousness, having discovered, so far as it was possible for her, what was below her, without going out of her way to seek it, nature produced an agreeable and brilliant object. If it is desired to attribute some sort of cognition or sensation to nature, these will resemble true cognition and sensation only as those of a man who is awake resemble those of a man who is asleep. For nature peaceably contemplates her object, which was born in her as effect of nature’s abiding within and with herself, of herself being an object of contemplation, and herself being a silent, if weak contemplation. There is, indeed, another power that contemplates more strongly; the nature which is the image of another contemplation. Consequently, what she has produced is very weak, because a weakened contemplation can beget a weak object only. [Ennead III,8 (30) 4]

(5). The purpose of action is to contemplate, and to possess the contemplated object. The object or activity, therefore, is contemplation. It seeks to achieve indirectly what it is unable to accomplish directly. It is not otherwise when one has achieved the object of one’s desires. One’s real desire is not to possess the desired object without knowing it, but to know it more thoroughly, to present it to the sight of the soul, and to be able to contemplate it therein. Indeed, activity always has in view some good; one desires to posses it interiorly, to appropriate it, and to possess the result of one’s action. Now as Good can be possessed only by the soul, activity once more brings us back to contemplation. Since the soul is a “reason,” what she is capable of possessing could be no more than a silent “reason,” being so much the more silent as it is more a “reason,” for perfect “reason” seeks nothing farther; it rests in the manifestation of that with which it is filled; the completer the manifestation, the calmer is the contemplation, and the more does it unite the soul. Speaking seriously, there is identity between knowing subject and known object in the actualization of knowledge. If they were not identical, they would be different, being alien to each other, without any real bond, just as reasons (are foreign to the soul) when they slumber within her, without being perceived. The reason must therefore not remain alien to the learning soul, but become united thereto, and become characteristic of her. Therefore when the soul has appropriated a “reason,” and has familiarized herself therewith, the soul as it were draws it out of her (breast) to examine it. Thus she observes the thing that she (unconsciously) possessed, and by examining it, distinguishes herself therefrom, and by the conception she forms of it, considers it as something foreign to her; for though the soul herself be a “reason” and a kind of intelligence, nevertheless when she considers something, she considers it as something distinct from herself, because she does not possess the true fulness, and is defective in respect to her principle (which is intelligence). Besides, it is with calmness that she observes what she has drawn from within herself; for she does not draw from within herself anything of which she did not formerly have even a notion. But she only drew from within herself that of which her view was incomplete, and which she wished to know better. In her actualizations (such as sensation), she adapts the “reasons” she possesses to exterior objects. On one hand, as she possesses (the intelligible entities) better than does nature, she is also calmer and more contemplative; on the other hand, as she does not possess (the intelligible entities) perfectly, more (than intelligence) she desires to have direct experimental knowledge and contemplation of the object she contemplates. After having (temporarily) withdrawn from her own higher part, and having (by discursive reason) run through the series of differences, she returns to herself, and again gives herself up to contemplation by her higher part (intelligence) from which she had withdrawn (to observe the differences); for the higher part does not deal with differences, as it abides within herself. Consequently the wise mind is identical with reason, and in itself possesses what it manifests to others. It contemplates itself; it arrives at unity not only in respect to exterior objects, but also in respect to itself; it rests in this unity, and finds all things within itself. [Ennead III,8 (30) 6]

(6). Thus everything (ultimately) derives from contemplation; everything (really) is contemplation, including the true beings, and the beings by the former secondarily begotten by giving themselves up to contemplation, and which themselves are objects of contemplation either for sensation, or for knowledge or opinion. Actions, and also desire, result in knowledge. Generation originates in speculation, and ends in the production of a form, that is: in an object of contemplation. In general, all beings that are images of generating principles produce forms and objects of contemplation. Begotten substances, being imitations of beings, show that the purpose of generating principles is neither generation nor action, but the production of works which themselves are to be contemplated. Contemplation is aimed at by both discursive thought, and beneath it, by sensation, the end of both of which is knowledge. Further, beneath discursive thought and sensation is the nature which, bearing within herself an object of contemplation, that is, a (“seminal) reason,” produces another “reason.” Such are the truths that are self-evident, or that can be demonstrated by reasoning. Besides it is clear that, since the intelligible objects devote themselves to contemplation, all other beings must aspire thereto; for the origin of beings is also their end. [Ennead III,8 (30) 7]

(7). Since contemplation rises by degrees, from nature to the Soul, from the Soul to Intelligence; and as within it thought becomes more and more (intimate or) interior, more and more united to the thinker; and as in the perfect Soul the things known are identical with the knower; and because they aspire to Intelligence, the subject must then evidently within Intelligence be identical with the object; not through any appropriation thereof, as the perfect Soul does indeed appropriate it, but because their essence (“being”) is identical, because of the identity between thinking and being (“essence”). Within intelligence no longer do we have on one side the object, and on the other the subject; otherwise we would need another principle where this difference would no longer exist. Within it, then, these two things, the subject and the object, form but a single (entity). That is a living contemplation, and no longer an object of contemplation which seems to inhere in something else; for existence within a living being is not identical with living by oneself. Therefore if it is to be alive, the object of contemplation and of thought must be life itself, and not the life of plants, that of sensation, or psychic life. Those are different thoughts, the one being the thought of plants, the thought of sensation, and psychic thought. They are thoughts because they are “reasons.” [Ennead III,8 (30) 8]

But how can one be united to beauty, without seeing it? If it be seen as some thing distinct from oneself, he is not yet fused with it. If the act of vision imply a relation with an exterior object, we have no vision; or, at least, this vision consists in the identity of seer and seen. This vision is a kind of conscience, of self-consciousness; and if this feeling be too acute, there is even danger of breaking up this unity. Besides, one must not forget that the sensations of evils make stronger impressions, and yield feebler knowledge, because the latter are frittered away by the force of impressions. Thus sickness strikes sharply (but arouses only an obscure notion); health, on the contrary, thanks to the calm that characterizes it, yields us a clearer notion of itself, for it remains quietly within us, because it is proper to us, and fuses with us. On the contrary, sickness is not proper to us, but foreign. Consequently it manifests itself vividly, because it is opposed to our nature; while we, on the contrary, enjoy but a feeble feeling of ourselves and of what belongs to us. The state in which we grasp ourselves best is the one in which our consciousness of ourselves fuses with us. Consequently on high, at the very moment when our knowledge by intelligence is at its best, we believe that we are ignorant of it, because we consult sensation, which assures us that it has seen nothing. Indeed it has not seen anything, and it never could see anything such (as the intelligible beings). It is therefore the sensation that doubts; but he who has the ability to see differs therefrom. Before the seer could doubt, he would have to cease believing in his very existence; for he could not, so to speak, externalize himself to consider himself with the eyes of the body. [Ennead V,8 (31) 11]

Surely, nobody could believe that the veritable and real Intelligence could be deceived, and admit the existence of things that do not exist? Its very name guarantees its intelligent nature. It therefore possesses knowledge without being subject to forgetfulness, and its knowledge is neither conjectural, doubtful, nor borrowed, nor acquired by demonstration. Even if we did admit that some of its knowledge was derived from demonstration, no one will deny that it possesses certain knowledge from within itself. It would be wiser, however, to be entirely reasonable and say that it derives everything from within itself. Without this, it would be difficult to distinguish what knowledge it derived from itself, and what was derived from outside. Even the certainty of the knowledge derived from itself would vanish, and it would lose the right to believe that things really are such as it imagines. Indeed, though the things whose knowledge we derive from the senses seem capable of producing in us the highest evidential value, it may still be asked whether their apparent nature do not derive more from modifications in us than from the objects themselves. Even so, belief in them demands assent of the intelligence, or at least of the discursive reason, for though we admit that things perceived by the senses exist in sensible objects, it is none the less recognized that what is perceived by sensation is only a representation of the exterior object, and that sensation does not reach to this object itself, since it remains exterior to sensation. But when intelligence cognizes, and is cognizing intelligibles, intelligence could never even meet them if they are cognized as lying outside of Intelligence. One explanation would be that intelligence does not at all meet them, nor cognize them. If it be by chance that intelligence meets them, the cognition of them will also be accidental and transient. The explanation that cognition operates by union of the intelligence with the intelligible depends on explanation of the bond that unites them. Under this hypothesis, the cognitions of the intelligible gathered by intelligence will consist of impressions (or, types) of reality, and will consequently be only accidental impressions. Such, however, could not exist in Intelligence; for what would be their form? As they would remain exterior to Intelligence, their knowledge would resemble sensation. The only distinction of this knowledge from sensation would be that intelligence cognizes more tenuous entities. Intelligence would never know that it really perceives them. It would never really know for certain that a thing was good, just or beautiful. In this case the good, just and beautiful would be exterior and foreign to it; Intelligence, in itself, will not possess any forms to regulate its judgments, and deserve its confidence; they, just as much as truth, would remain outside of it. [Ennead V,5 (32) 1]

On the other hand, the intelligible entities are either deprived of feeling, life and intelligence, or they are intelligent. If they be intelligent, they, like truth, fuse with intelligence into the primary Intelligence. In this case we shall have to inquire into the mutual relations of intelligence, intelligible entity, and truth. Do these constitute but one single entity, or two? What in the world could intelligible entities be, if they be without life or intelligence? They are surely neither propositions, axioms, nor words, because in this case they would be enunciating things different from themselves, and would not be things themselves; thus, when you say that the good is beautiful, it would be understood that these two notions are foreign to each other. Nor can we think that the intelligibles — for instance, beauty and justice — are entities that are simple, but completely separate from each other; because the intelligible entity would have lost its unity, and would no longer dwell within a unitary subject. It would be dispersed into a crowd of particular entities, and we would be forced to consider into what localities these divers elements of the intelligible were scattered. Besides, how could intelligence embrace these elements and follow them in their vicissitudes? How could intelligence remain permanent? How could it fix itself on identical objects? What will be the forms or figures of the intelligibles? Will they be like statues of gold, or like images and effigies made of some other material? In this case, the intelligence that would contemplate them would not differ from sensation. What would be the differentiating cause that would make of one justice, and of the other something else? Last, and most important, an assertion that the intelligible entities are external to Intelligence would imply that in thus contemplating objects exterior to itself Intelligence will not gain a genuine knowledge of them, having only a false intuition of them. Since, under this hypothesis, true realities will remain exterior to Intelligence, the latter, while contemplating them, will not possess them; and in knowing them will grasp only their images. Thus reduced to perceiving only images of truth, instead of possessing truth itself, it will grasp only deceptions, and will not reach realities. In this case (intelligence will be in the dilemma) of either acknowledging that it grasps only deceptions, and thus does not possess truth; or intelligence will be ignorant of this, being persuaded it possesses truth, when it really lacks it. By thus doubly deceiving itself, intelligence will by that very fact be still further from the truth. That is, in my opinion, the reason why sensation cannot attain the truth. Sensation is reduced to opinion because it is a receptive power — as indeed is expressed by the word “opinion”; — and because sensation receives something foreign, since the object, from which sensation receives what it possesses remains external to sensation. Therefore, to seek truth outside of intelligence is to deprive intelligence of truth or verity of intelligence. It would amount to annihilating Intelligence, and the truth (which was to dwell within it) will no longer subsist anywhere. [Ennead V,5 (32) 1]

Those who complain of the nature of the world do not know what they are doing, nor the extent of their audacity. Many men are ignorant of the close concatenation which unites the entities of the first, second, and third ranks, and which descends even to those of the lowest degree. Instead of blaming what is subordinate to first principles, we should gently submit to the laws of the universe, rise to first principles, not undergo those tragic terrors, inspired in certain people by the spheres of the world which exert on us nothing but a beneficent influence. What is so terrible in them? Why should they be feared by these men foreign to philosophy and all sound learning? Though celestial spheres do have fiery bodies, they should not inspire us with any fear, because they are perfectly harmonious with the universe and with the earth. We must besides consider the souls of the stars to which those (Gnostics) consider themselves so superior, while their bodies, which surpass ours so much in size and beauty, efficaciously concur in the production of things that are conformed to the order of nature; for such things could not be born if first principles alone existed. Finally the stars complete the universe, and are important members thereof. If even man holds a great superiority over animals, there must be a far greater superiority in those stars which exist as ornaments to the universe, and to establish order therein, and not to exert thereover a tyrannical influence. The events that are said to flow from the stars are rather signs thereof than causes. Besides, the events that really do flow from the stars differ among each other by circumstances. It is not therefore possible that the same things should happen to all men, separated as they are by their times of birth, the places of their residence, and the dispositions of their souls. It is just as unreasonable to expect that all would be good, nor, because of the impossibility of this, to go and complain on the grounds that all sense-objects should be similar to intelligible objects. Moreover, evil is nothing but what is less complete in respect to wisdom, and less good, in a decreasing gradation. For instance, nature (that is, the power of growth and generation) should not be called evil because she is not sensation; nor sensation be called evil, because it is not reason. Otherwise, we might be led to think that there was evil in the intelligible world. Indeed, the Soul is inferior to Intelligence, and Intelligence is inferior to the One. [Ennead II,9 (33) 13]

(To solve this problem) let us begin by setting aside sensation, and let us contemplate Intelligence by our intelligence exclusively. Above all, let us clearly understand that, as in us life and intelligence do not consist of a corporeal mass, but in a power without mass, likewise veritable “Being” is deprived of all corporeal extension, and constitutes a power founded on itself. It does not indeed consist in something without force, but in a power sovereignly vital and intellectual, which possesses life in the highest degree, intelligence, and being. Consequently, whatever touches this power participates in the same characteristics according to the manner of its touch; in a higher degree, if the touch be close; in a lower degree, if the touch be distant. If existence be desirable, the completest existence (or, essence) is more desirable still. Likewise, if intelligence deserve to be desired, perfect Intelligence deserves to be desired above everything; and the same state of affairs prevails in respect to life. If then we must grant that the Essence is the first, and if we must assign the first rank to Essence, the second to Intelligence, and the third to the Organism, as the latter seems already to contain all things, and Intelligence justly occupies the second rank, because it is the actualization of “Being” — then number could not enter into the Organism, for before the organism already existed one and two (“Being” and Intelligence). Nor could number exist in Intelligence, for before Intelligence was “Being,” which is both one and manifold. (Number therefore must exist, or originate, in the primary Being.) [Ennead VI,6 (34) 8]

What is the relation of the sense-power within the superior Soul (or, in the rational soul)? Intelligible sensation perceives (intelligible) objects that, speaking strictly, are not sensible, and corresponds to the (intelligible) manner in which they are perceivable. Thus (by this intelligible sense-power) the Soul perceives the supersensual harmony and also the sensual, but in a manner such as the sense-man perceives it, relating it so far as possible to the superior harmony, just as he relates the earthly fire to the intelligible Fire, which is above, and which the superior Soul felt in a manner suitable to the nature of this fire. If the bodies which are here below were up there also, the superior Soul would feel them and perceive them. The man who exists on high is a Soul disposed in some particular manner, capable of perceiving these objects; hence the man of the last degree (the sense-man) being the image of the intelligible Man, has reasons (faculties) which are also images (faculties possessed by the superior Man). The man who exists in the divine Intelligence constitutes the Man superior to all men. He illuminates the second (the reasonable man), who in his turn illuminates the third (the sense-man). The man of this last degree somewhat possesses the two others; he is not produced by them, he is rather united to them. The man who constitutes us actualizes himself as the man of the last degree. The third receives something of the second; and the second is the actualization of the first. Each man’s nature depends on the “man” according to whom he acts (the man is intellectual, reasonable, or sensual according as he exercises intelligence, discursive reason, or sensibility). Each one of us possesses the three men in one sense (potentially); and does not possess them in another (in actualization; that is, he does not simultaneously exercise intellect, reason, or sense). [Ennead VI,7 (38) 6]

Such considerations have been arrived at merely as result of scrutiny of the consequences of the principles laid down. Our purpose was to discover how sensibility occurs in the man himself, without intelligible things falling into generation. We recognized and demonstrated that intelligible things do not incline towards sense-things, but that, on the contrary, it is the latter that aspire and rise to the former, and imitate them; that the sense-man derives from the intellectual man the power of contemplating intelligible entities, though the sense-man remain united to sense-things, as the intellectual man remains united to the intelligible entities. Indeed, intelligible things are in some respects sensual; and we may call them such because (ideally) they are Bodies, but they are perceived in a manner different from bodies. Likewise, our sensations are less clear than the perception which occurs in the intelligible world, and that we also call Sensation, because it refers to Bodies (which exist on high only in an ideal manner). Consequently, we call the man here below sensual because he perceives less well things which themselves are less good; that is, which are only images of intelligible things. We might therefore say that sensations here below are obscure thoughts, and that the Thoughts on high are distinct Sensations. Such are our views about sensibility. [Ennead VI,7 (38) 7]

The good must then be desirable; but it is good not because it is desirable, but it is desirable because it is good. Thus in the order of beings, rising from the last to the First, it will be found that the good of each of them is in the one immediately preceding, so long as this ascending scale remain proportionate and increasing. Then we will stop at Him who occupies the supreme rank, beyond which there is nothing more to seek. That is the First, the veritable, the sovereign Good, the author of all goodness in other beings. The good of matter is form; for if matter became capable of sensation it would receive it with pleasure. The good of the body is the soul; for without her it could neither exist nor last. The good of the soul is virtue; and then higher (waits), Intelligence. Last, the good of Intelligence is the principle called the Primary nature. Each of these goods produces something within the object whose good it is. It confers order and beauty (as form does on matter); or life (as the soul does on the body); or wisdom and happiness (as intelligence does on soul). Last, the Good communicates to Intelligence its influx, and actualization emanating from the Good, and shedding on Intelligence what has been called the light of the Good. The nature of this we shall study later. [Ennead VI,7 (38) 25]

Recognition of goodness and so-called “possession” thereof consist of enjoyment of the presence of good by the being who has received from nature the faculty of sensation. How could it make a mistake about the matter? The possibility of its being deceived implies the existence of some counterfeit; in this case, the error of this being was caused by that which resembled its good; for this being withdraws from what had deceived it as soon as the Good presents itself. The existence of a particular good for each being is demonstrated by its desire and inclination. Doubtless, the inanimate being receives its good from without; but, in the animated being, the desire spontaneously starts to pursue the Good. That is why lifeless bodies are the objects of solicitude and care of living beings, while the living beings watch over themselves. [Ennead VI,7 (38) 26]

All we have said above goes on the assumption that matter is the evil. But if it were something else, as, for instance, malice, and if the essence of matter were to receive sensation, would intimacy with what is better still be the good of matter? But if it were not the malice itself of matter which choose the good, it was what had become evil in matter. If the essence (of matter) were identical with evil, how could matter wish to possess this good? Would evil love itself, if it had self-consciousness? But how could that which is not lovable be loved? For we have demonstrated that a being’s good does not consist in that which is suitable to it. Enough about this, however. [Ennead VI,7 (38) 28]

This is proved by what happens to lovers; so far as their eyes remain fixed on a sense-object, they do not yet love genuinely. Love is born only when they rise above the sense-object, and arrive at representing in their indivisible soul an image which has nothing more of sensation. To calm the ardor that devours them they do indeed still desire to contemplate the beloved object; but as soon as they come to understand that they have to rise to something beyond the form, they desire the latter; for since the very beginning they felt within themselves the love for a great light inspired by a feeble glow. The Shape indeed is the trace of the shapeless. Without himself having any shape, He begets shape whenever matter approaches Him. Now matter must necessarily be very distant from Him, because matter does not possess forms of even the last degree. Since form inherent in matter is derived from the soul, not even mere form-fashioned matter is lovable in itself, as matter; and as the soul herself is a still higher form, but yet is inferior to and less lovable than intelligence, there is no escape from the conclusion that the primary nature of the Beautiful is superior to form. [Ennead VI,7 (38) 33]

Some person might try to establish a distinction founded on the fact that the animal and the soul do not act unconsciously. If they know it by mere sensation, how far does that sensation contribute to the freedom of will? For sensation, limiting itself to perception, does not yield the percipient mastery over anything. If they know it by knowledge, and if this knowledge contain only the accomplished fact, their actions are then determined by some other principle. If, even independently of desire, reason or knowledge make us perform certain actions, or dominate us, to what faculty shall the action be ascribed, and how does it occur? If reason produce another desire, how does it do so? If reason manifest itself and liberate us by the process of calming our desires, the free will lies no longer in the action, but in intelligence; for every action, however much directed by reason, would then be something mixed, not revealing an unconfused free will. [Ennead VI,8 (39) 2]

If we deny that sensations are images impressed on the soul, similar to the impression of a seal, we shall also, for the sake of consistency, have to deny that memories are notions or sensations preserved in the soul by the permanence of the impression, inasmuch as, according to our opinion, the soul did not originally receive any impression. The two questions, therefore, hang together. Either we shall have to insist that sensation consists in an image impressed on the soul, and memory, in its preservation; or, if either one of these opinions be rejected, the other will have to be rejected also. However, since we regard both of them as false, we shall have to consider the true operation of both sensation and memory; for we declare that sensation is as little the impression of an image as memory is its permanence. The true solution of the question, on the contrary, will be disclosed by an examination of the most penetrating sense, and then by induction transferring the same laws to the other senses. [Ennead IV,6 (41) 8]

In general the sensation of sight consists of perception of the visible object, and by sight we attain it in the place where the object is placed before our eyes, as if the perception operated in that very place, and as if the soul saw outside of herself. This occurs, I think, without any image being produced nor producing itself outside of the soul, without the soul receiving any impression similar to that imparted by the seal to the wax. Indeed, if the soul already in herself possessed the image of the visible object, the mere possession of this image (or type) would free her from the necessity of looking outside of herself. The calculation of the distance of the object’s location, and visibility proves that the soul does not within herself contain the image of the object. In this case, as the object would not be distant from her, the soul would not see it as located at a distance. Besides, from the image she would receive from within herself, the soul could not judge of the size of the object, or even determine whether it possessed any magnitude at all. For instance, taking as an example the sky, the image which the soul would develop of it would not be so great (as it is, when the soul is surprised at the sky’s extent). Besides, there is a further objection, which is the most important of all. If we perceive only the images of the objects we see, instead of seeing the objects themselves, we would see only their appearances or adumbrations. Then the realities would differ from the things that we see. The true observation that we cannot discern an object placed upon the pupil, though we can see it at some little distance, applies with greater cogency to the soul. If the image of the visible object be located within her, she will not see the object that yields her this image. We have to distinguish two things, the object seen, and the seeing subject; consequently, the subject that sees the visible object must be distinct from it, and see it as located elsewhere than within itself. The primary condition of the act of vision therefore is, not that the image of the object be located in the soul, but that it be located outside of the soul. [Ennead IV,6 (41) 8]

After denying that sensation consists of such an operation, it is our duty to point out the true state of affairs. Though it be objected that thus the soul would be considered as judging of things she does not possess, it is nevertheless plain that it is the characteristic of a power, not to experience or suffer, but to develop its force, to carry out the function to which it is destined. If the soul is to discern a visible or audible object the latter must consist of neither images nor experiences, but actualizations relative to the objects which naturally belong to the domain of these actualizations of the soul. Those who deny that any faculty can know its object without receiving some impulsion from it imply that the faculty suffers, without really cognizing the object before it; for this soul-faculty should dominate the object instead of being thereby dominated. [Ennead IV,6 (41) 2]

The case of hearing is similar to that of sight. The impression is in the air; the sounds consist in a series of distinct vibrations, similar to letters traced by some person who is speaking. By virtue of her power and her being, the soul reads the characters traced in the air, when they present themselves to the faculty which is suitable to reception of them. As to taste and smell also, we must distinguish between the experience and the cognition of it; this latter cognition constitutes sensation, or a judgment of the experience, and differs therefrom entirely. [Ennead IV,6 (41) 2]

Still another argument: in sensations, it is not the weak and impotent organ which perceives by itself; it is not, for instance, the eye that sees, but the active potentiality of the soul. That is why old people have both sensations and memories that are weaker. Both sensation and memory, therefore, imply some energy. [Ennead IV,6 (41) 3]

Last, as we have seen that sensation is not the impression of an image in the soul, memory could not be the storage-place of images it could not have received. [Ennead IV,6 (41) 3]

Let us now consider relation. Let us see whether, in relative matters, there be something common that constitutes a kind, or which is a point of union in any other manner. Let us, before everything else, examine whether relation (as, for example, left and right, double and half, and so forth) be a kind of “hypostasis,” or substantial act, or an habituation; or, whether it be a kind of hypostatic existence in certain things, while in others it is not so; or whether it be this under no circumstances. What is there indeed that is particular in relations such as double and half; surpasser and surpassed; in possession, and in disposition; lying down, standing, sitting; in the relation of father and son; of master and slave; in the like and different; the equal and unequal; the active and passive; measurer and measured; sensation and knowledge? Knowledge, for instance, relates to the object which can be known, and sensation to sense-object; for the relation of knowledge to the object which can be known has a kind of hypostatic existence in the actualization relative to the form of the object which can be known; likewise with the relation of sensation to the sense-object. The same may be said about the relation of the “active” to the “passive,” which results in a single actualization, as well as about the relation between the measure and the measured object, from which results mensuration. But what results from the relation of the similar to the similar? If in this relation there be nothing begotten, one can at least discover there something which is its foundation, namely, the identity of quality; nevertheless, neither of these two terms would then have anything beside their proper quality. The same may be said of equal things, because the identity of quantity precedes the manner of being of both things; this manner of being has no foundation other than our judgment, when we say, This one or that one are of the same size; this one has begotten that one, this one surpasses that one. What are standing and sitting outside of him who stands or sits? As to the possession, if it apply to him who possesses, it rather signifies the fact of possession; if it apply to what is possessed, it is a quality. As much can be said of disposition. What then exists outside of the two relative terms, but the comparison established by our judgment? In the relation of the thing which surpasses the thing which is surpassed, the first is some one size, and the second is some other size; those are two independent things, while as to the comparison, it does not exist in them, except in our judgment. The relation of left to right and that of the former to the latter consist in the different positions. It is we who have imagined the distinction of right to left; there is nothing in the objects themselves that answers thereto. The former and the latter are two relations of time, but it is we who have established that distinction. [Ennead VI,1 (42) 6]

It must therefore be granted that in the things of which we first spoke, such as knowing and doing (active being), there is an actualization, an habituation, and an actualizing reason; while in the other things there is a participation in form and reason. For indeed, if the bodies were the only essences, the relative habituations would bear no reality. If, on the contrary, we assign the first rank in existence to incorporeal things, and to the reasons, and if we define the habituations as reasons that participate in the forms, we should say that what is double has the double for its cause, and what is half, has the half as its cause; and that other things are what they are named because of the presence of the same, or of the contrary form. Now either two things simultaneously receive one the double, and the other the half, and one greatness, and the other smallness; or contraries such as resemblance and dissimilarity are to be found in each thing, as well as identity and difference; and everything finds itself simultaneously similar and dissimilar, identical and different. It might be objected that if one object were ugly, and another uglier still, they are such because they participate in a form. Not so; for if these two objects be equally ugly, they are equal in the absence of the form. If they be unequally ugly, the least ugly is such because it participates in a form which does not sufficiently subdue matter, and the uglier is such because it participates in a form which does so still less. They could, besides, be judged from the standpoint of deprivation, comparing them to each other as if they contained some form. The sensation is a form that results from two things (of that which feels, and that which is felt); so also with knowledge. In respect to the thing possessed, possession is an act which contains, which has a kind of efficacy. As to mensuration, which is an actualization of measure, in respect of the measured object, it consists in a reason. [Ennead VI,1 (42) 9]

We must further examine if the Aristotelians have the right to say that acting contains both actualizations and movements, the actualizations producing themselves instantaneously, and the movements successively; as, for instance, dividing implies time. Or will they say that all actualizations are movements, or, at least, are accompanied by movements? Will they trace all actions to “experiencing” (or, reactions), or will they acknowledge absolute actions, like walking or speaking? Or will they distinguish all actions that relate to “experiencing” as movements, and all absolute actions as actualizations? Or will they place actions of both kinds among movements, and among actualizations? They would no doubt classify walking, which is an absolute thing, as movement; and thinking, which is a verb without passive voice, as an actualization. Otherwise the Aristotelians will be obliged to insist that there is nothing active in walking or thinking. But if walking and thinking do not belong to the category of acting, it will be necessary to explain to what they do belong. Will it be said that thinking relates to the thinkable (the intelligible), as intellection does, because sensation relates to the sense-object? If sensation be related to the sense-object, why do they not equally relate “sensing” (feeling) to the sense-object? Sensation, relating to something else, has a relation with that thing; but, besides that relation, it has the property of being an “action” or an “experience” (or, reaction). If therefore reaction (or, suffering), besides belonging to something else, or depending on something else, has the property of itself being something, like actualization, then walking, besides belonging to something else (to the feet), and depending on something else (on the motive power), nevertheless by itself possesses the property of being movement. In this case, it will have to be recognized that intellection, besides being a relation, by itself also is a movement or an actualization. [Ennead VI,1 (42) 18]

Thus, in everything, acting forms but a single genus along with reacting, which (by the Aristotelians) is considered its opposite. Reacting is what follows acting, without being its contrary; to be burnt, for instance, follows burning, but is not its contrary. In this case, the reaction is what results in the object itself from the fact of burning, or of being burnt, which form but one (process), whether the result be suffering, or something else, as, for instance, depreciation. It might be objected, When one (being) makes another suffer, is it not true that the one acts, and the other reacts? Here from a single actualization result two facts, an action, and a reaction. Besides, it is not necessary to include in the action the will to cause suffering; it has only produced something else as a result of which it causes suffering, something which occurring in the being that suffers, and being one single (occurrence), that causes suffering. What then is this one identical thing which is anterior to the suffering? When there is no suffering, is there not nevertheless a reaction in him in whom is the modification? For instance, in him who hears? No: to hear is not to react, and sensation is not really a reaction; but to suffer is to experience a reaction, and the reaction is not the contrary of the action (in the sense we have explained). [Ennead VI,1 (42) 19]

The Stoic theory raises numberless further objections; but we halt here lest we ourselves incur ridicule in combating so evident an absurdity. It suffices if we have demonstrated that these philosophers mistake non-essence for absolute essence; (putting the cart before the horse), they assign the First rank to what should occupy the last. The cause of their error is that they have chosen sensation as guide, and have consulted nothing else in determining both their principles, and consequences. Being persuaded that the bodies are genuine essences, and refusing to believe that they transform themselves into each other, they believed that what subsisted in them (in the midst of their changes) is the real essence, just as one might imagine that place, because it is indestructible, is more essential than (metabolic) bodies. Although in the system of the Stoics place remain unaltered, these philosophers should not have regarded as essence that which subsists in any manner soever; they should, first, have considered what are the characteristics necessarily possessed by essence, the presence of which (characteristics) makes it subsist without undergoing any alteration. Let us indeed suppose that a shadow would continuously subsist by following something which changes continuously; the shadow, however, would not be no more real than the object it follows. The sense-world, taken together with its multiple objects, is more of an essence than the things it contains, merely because it is their totality. Now if this subject, taken in its totality, be non-essence, how could it be a subject? The most surprising thing, however, is that the (Stoics), in all things following the testimony of sensation, should not also have affirmed that essence can be perceived by sensation; for, to matter, they do not attribute impenetrability, because it is a quality (and because, according to them, matter has no quality). If they insist that matter is perceived by intelligence, it could only be an irrational intelligence which would consider itself inferior to matter, and attribute to it, rather than to itself, the privilege of constituting genuine essence. Since in their system intelligence is non-essence, how could any credibility attach to that intelligence when it speaks of things superior to it, and with which it possesses no affinity? But we have said enough of the nature of these subjects, elsewhere. [Ennead VI,1 (42) 28]

Besides, it is not necessary to divide the combination in form and matter, now that we speak of sense-being, a “being” which has to be perceived by the senses, rather than by reason. Neither is it necessary to add of what this being is composed; for the elements which compose it are not beings, or at least not sense-beings. What has to be done here is to embrace in a single genus what is common to stone, to earth, to water, and to the things compounded of them; namely, to plants and animals so far as they respond to sensation. In this way, we shall consider both form and matter; for sense-being contains them both. Thus fire, earth, and their intermediaries are both matter and form; as to the combinations, they contain several beings united together. What then is the common characteristic of all these beings, which separates them from other things? They serve as subjects to other things, and are not contained in one subject, and do not belong to something else; in short, all the characteristics we have enumerated above suit sense-being. [Ennead VI,3 (44) 8]

But how is white distinguished from black? Sensation or intelligence tell us that those things are different without informing us of their reason; either sensation, because its function is not to set forth the reason of things, but only to bring them somehow to our attention; or intelligence, because it discerns things that are simple by intuition, without having to resort to ratiocination, and limits itself to the statement that something is such or such. Besides, in each one of the operations of intelligence there is a difference (a special distinctive characteristic) which enables it to distinguish different things, without this difference (which is proper to each of the operations of intelligence) itself having need to be discerned by the help of some other difference. [Ennead VI,3 (44) 18]

Those who deny the privilege of living well to plants, because these lack sensation, are not on that account obliged to grant it to all animals. For, if sensation consist in the knowledge of the experienced affection, this affection must already be good before the occurrence of the knowledge. For instance, the being must be in a state conformable to nature even though ignorant thereof. He must fulfil his proper function even when he does not know it. He must possess pleasure before perceiving it. Thus if, by the possession of this pleasure, the being already possesses the Good, he thereby possesses even well-being. What need then is there to join thereto sensation, unless indeed well-being be defined as sensation and knowledge (of an affection or state of the soul) rather than in the latter affection and state of the soul itself? [Ennead I,4 (46) 2]

The Good would thus be reduced to no more than sensation, or the actualization of the sense-life. In this case, to possess it, it is sufficient to perceive irrespective of the content of that perception. Other persons might assert that goodness results from the union of these two things: of the state of the soul, and of the knowledge the soul has of it. If then the Good consist in the perception of some particular state, we shall have to ask how elements which, by themselves, are indifferent could, by their union, constitute the good. Other theories are that the Good consists in some particular state, or in possession of some particular disposition, and conscious enjoyment of the presence of the Good. These would, however, still have to answer the question whether, for good living, it be sufficient that the being knows he possesses this state; or must he know not only that this state is pleasant, but also that it is the Good? If then it be necessary to realize that it is the Good, the matter is one no longer of the function of sensation, but of a faculty higher than the senses. To live well, in this case, it will no longer be sufficient to possess pleasure, but we shall have to know that pleasure is the Good. The cause of happiness will not be the presence of pleasure itself, but the power of judging that pleasure is a good. Now judgment is superior to affection; it is reason or intelligence, while pleasure is only an affection, and what is irrational could not be superior to reason. How would reason forget itself to recognize as superior what is posited in a genus opposed to it? These men who deny happiness to plants, who explain it as some form of sensation, seems to us, in spite of themselves, to be really seeking happiness of a higher nature, and to consider it as this better thing which is found only in a completer life. [Ennead I,4 (46) 2]

There is a greater chance of being right in the opinion that happiness consists in the reasonable life, instead of mere life, even though united to sensation. Still even this theory must explain why happiness should be the privilege of the reasonable animal. Should we add to the idea of an animal the quality of being reasonable, because reason is more sagacious, more skilful in discovering, and in procuring the objects necessary to satisfy the first needs of nature? Would you esteem reason just as highly if it were incapable of discovering, or procuring these objects? If we value reason only for the objects it aids us in getting, happiness might very well belong to the very irrational beings, if they are, without reason, able to procure themselves the things necessary to the satisfaction of the first needs of their nature. In this case, reason will be nothing more than an instrument. It will not be worth seeking out for itself, and its perfection, in which virtue has been shown to consist, will be of little importance. The opposite theory would be that reason does not owe its value to its ability to procure for us objects necessary to the satisfaction of the first needs of nature, but that it deserves to be sought out for itself. But even here we would have to explain its function, its nature, and set forth how it becomes perfect. If it were to be improvable, it must not be defined as the contemplation of sense-objects, for its perfection and essence (being) consist in a different (and higher) function. It is not among the first needs of nature, nor among the objects necessary to the satisfaction of its needs; it has nothing to do with them, being far superior. Otherwise, these philosophers would be hard pressed to explain its value. Until they discover some nature far superior to the class of objects with which they at present remain, they will have to remain where it suits them to be, ignorant of what good living is, and both how to reach that goal, and to what beings it is possible. [Ennead I,4 (46) 2]

Since the work under consideration is the entire world, we would, were our intelligence attentively to listen to its voice, hear it exclaim as follows: “It is a divinity who has made Me, and from the divinity’s hands I issued complete, including all animated beings, entire and self-sufficient, standing in need of nothing, since everything is contained within Me; plants, animals, the whole of Nature, the multitude of the divinities, the troupe of guardians, excellent souls, and the men who are happy because of virtue. This refers not only to the earth, which is rich in plants and animals of all kinds; the power of the Soul extends also to the sea. Nor are the air and entire heaven inanimate. They are the seat of all the excellent Souls, which communicate life to the stars, and which preside over the circular revolution of the heaven, a revolution that is eternal and full of harmony, which imitates the movement of Intelligence by the eternal and regular movement of the stars around one and the same centre, because heaven has no need to seek anything outside of itself. All the beings I contain aspire to the Good; all achieve Him, each according to its potentiality. Indeed, from the Good depends the entire heaven, my whole Soul, the divinities that inhabit my various parts, all the animals, all the plants, and all my apparently inanimate beings. In this aggregation of beings some seem to participate only in existence, others in life, others in sensation, others in intelligence, while still others seem to participate in all the powers of life at one time; for we must not expect equal faculties for unequal things, as for instance sight for the fingers, as it is suitable to the eye; while the finger needs something else; it needs its own form, and has to fulfil its function.” [Ennead III,2 (47) 3]

Although I am able to make any desired decision, nevertheless my decision enters into the plan of the universe, because my nature has not been introduced into this plan subsequently; but it includes me and my character. But whence originates my character? This includes two points: is the cause of any man’s character to be located in Him who formed him, or in that man himself? Must we, on the other hand, give up seeking its cause? Surely: just as it is hopeless to ask why plants have no sensation, or why animals are not men; it would be the same as asking why men are not gods. Why should we complain that men do not have a more perfect nature, if in the case of plants and animals nobody questions or accuses either these beings themselves, nor the power which has made them? (This would be senseless, for two reasons): if we say that they might have been better, we are either speaking of the qualities which each of them is capable of acquiring by himself; and in this case we should blame only him who has not acquired them — or, we are speaking of those qualities which he should derive not from himself, but from the Creator, in which case it would be as absurd to claim for man more qualities than he has received, than it would be to do so in the case of plants or animals. What we should examine is not if one being be inferior to another, but if it be complete within its own sphere; for evidently natural inequalities are unavoidable. This again depends on conformity to nature, not that inequalities depend on the will of the principle which has regulated all things. [Ennead III,3 (48) 3]

Men (therefore, not being only what they were made) possess another principle (free intelligence with reason); but not all make use of all the principles they possess; some make use of the one<one principle (their intelligence), while others make use of the other (principle of reason), or even of the lower principle (of imagination and sensation). All these principles are present in the man, even when they do not react on him; and even in this case, they are not inert; each fulfils its peculiar office; only they do not all act simultaneously upon him (or, are not perceived by his consciousness). It may seem difficult to understand how this may be the case with all of them present, and it might seem easier to consider them absent; but they are present in us, in the sense that we lack none of them; although we might consider them absent in the sense that a principle that does not react on a man might be considered absent from him. It might be asked why these principles do not react on all men, since they are part of them? We might, referring chiefly to this (free, intelligent, reasonable) principle, say that first, it does not belong to animals; second, it is not even (practiced) by all men. If it be not present in all men, so much the more is it not alone in them, because the being in whom this principle alone is present lives according to this principle, and lives according to other principles only so far as he is compelled by necessity. The cause (which hinders intelligence and reason from dominating us) will have to be sought in the (Stoic) substrate of the man, either because our corporeal constitution troubles the superior principle (of reason and intelligence), or because of the predominance of our passions. [Ennead III,3 (48) 4]

Must thought, and self-consciousness imply being composed of different parts, and on their mutual contemplation? Must that which is absolutely simple be unable to turn towards itself, to know itself? ls it, on the contrary, possible that for that which is not composite to know itself? Self-consciousness, indeed, does not necessarily result from a thing’s knowing itself because it is composite, and that one of its parts grasps the other; as, for instance, by sensation we perceive the form and nature of our body. In this case the whole will not be known, unless the part that knows the others to which it is united also knows itself; otherwise, we would find the knowledge of one entity, through another, instead of one entity through itself. [Ennead V,3 (49) 1]

While, therefore, asserting that a simple principle does know itself, we must examine into the possibility of this. Otherwise, we would have to give up hope of real self-knowledge. But to resign this would imply many absurdities; for if it be absurd to deny that the soul possesses self-knowledge, it would be still more absurd to deny it of intelligence. How could intelligence have knowledge of other beings, if it did not possess the knowledge and science of itself? Indeed, exterior things are perceived by sensation, and even, if you insist, by discursive reason and opinion; but not by intelligence. It is indeed worth examining whether intelligence does, or does not have knowledge of such external things. Evidently, intelligible entities are known by intelligence. Does intelligence limit itself to knowledge of these entities, or does it, while knowing intelligible entities, also know itself? In this case, does it know that it knows only intelligible entities, without being able to know what itself is? While knowing that it knows what belongs to it, is it unable to know what itself, the knower, is? Or can it at the same time know what belongs to it, and also know itself? Then how does this knowledge operate, and how far does it go? This is what we must examine. [Ennead V,3 (49) 1]

Besides the above, the soul possesses the discursive reason, which judges of sense-representations, combining and dividing them. Under the form of images, she also considers the conceptions received from intelligence, and operates on these images as on images furnished by sensation. Finally, she still is the power of understanding, since she distinguishes the new images from the old, and harmonizes them by comparing them; whence, indeed, our reminiscences are derived. [Ennead V,3 (49) 2]

But why should this whole (soul-) part that is superior to sensation be assigned to the soul rather than to intelligence? Because the power of the soul consists in reasoning, and because all these operations belong to the discursive reason. But why can we not simply assign to it, in addition, self-consciousness, which would immediately clear up this inquiry? Because the nature of discursive reason consists in considering exterior things, and in scrutinizing their diversity, while to intelligence we attribute the privilege of contemplating itself, and of contemplating its own contents. But what hinders discursive reason, by some other faculty of the soul, from considering what belongs to it? Because, in this case, instead of discursive reason and reasoning, we would have pure Intelligence. But what then hinders the presence of pure Intelligence within the soul? Nothing, indeed. Shall we then have a right to say that pure Intelligence is a part of the soul? No indeed; but still we would have the right to call it “ours.” It is different from, and higher than discursive reason; and still it is “ours,” although we cannot count it among the parts of the soul. In one respect it is “ours,” and in another, is not “ours;” for at times we make use of it, and at other times we make use of discursive reason; consequently, intelligence is “ours” when we make use of it; and it is not “ours” when we do not make use of it. But what is the meaning of “making use of intelligence”? Does it mean becoming intelligence, and speaking in that character, or does it mean speaking in conformity with intelligence? For we are not intelligence; we speak in conformity with intelligence by the first part of discursive reason, the part that receives impressions from Intelligence. We feel through sensation, and it is we who feel. Is it also we who conceive and who simultaneously are conceived? Or is it we who reason, and who conceive the intellectual notions which enlighten discursive reason? We are indeed essentially constituted by discursive reason. The actualizations of Intelligence are superior to us, while those of sensation are inferior; as to us, “we” are the principal part of the soul, the part that forms a middle power between these two extremes, now lowering ourselves towards sensation, now rising towards Intelligence. We acknowledge sensibility to be ours because we are continually feeling. It is not as evident that intelligence is ours, because we do not make use of it continuously, and because it is separated, in this sense, that it is not intelligence that inclines towards us, but rather we who raise our glances towards intelligence. Sensation is our messenger, Intelligence is our king. [Ennead V,3 (49) 3]

We must, therefore, contemplate the soul and her divinest part in order to discover the nature of Intelligence. This is how we may accomplish it: From man, that is from yourself, strip off the body; then that power of the soul that fashions the body; then sensation, appetite, and anger, and all the lower passions that incline you towards the earth. What then remains of the soul is what we call the “image of intelligence,” an image that radiates from Intelligence, as from the immense globe of the sun radiates the surrounding luminary sphere. Of course, we would not say that all the light that radiates from the sun remains within itself around the sun; only a part of this light remains around the sun from which it emanates; another part, spreading by relays, descends to us on the earth. But we consider light, even that which surrounds the sun, as located in something else, so as not to be forced to consider the whole space between the sun and us as empty of all bodies. On the contrary, the soul is a light which remains attached to Intelligence, and she is not located in any space because Intelligence itself is not spatially located. While the light of the sun is in the air, on the contrary the soul, in the state in which we consider her here, is so pure that she can be seen in herself by herself, and by any other soul that is in the same condition. The soul needs to reason, in order to conceive of the nature of Intelligence according to her own nature; but Intelligence conceives of itself without reasoning because it is always present to itself. We, on the contrary, are present both to ourselves and to Intelligence when we turn towards it, because our life is divided into several lives. On the contrary, Intelligence has no need of any other life, nor of anything else; what Intelligence gives is not given to itself, but to other things; neither does Intelligence have any need of what is inferior to it; nor could Intelligence give itself anything inferior, since Intelligence possesses all things; instead of possessing in itself the primary images of things (as in the case of the soul), Intelligence is these things themselves. [Ennead V,3 (49) 9]

If one should find himself unable to rise immediately to pure thought, which is the highest, or first, part of the soul, he may begin by opinion, and from it rise to Intelligence. If even opinion be out of the reach of his ability, he may begin with sensation, which already represents general forms; for sensation which contains the forms potentially may possess them even in actualization. If, on the contrary, the best he can do is to descend, let him descend to the generative power, and to the things it produces; then, from the last forms, one may rise again to the higher forms, and so on to the primary forms. [Ennead V,3 (49) 9]

This Principle, therefore, is really indescribable. We are individualizing it in any statement about it. That which is above everything, even above the venerable Intelligence, really has no name, and all that we can state about Him is, that He is not anything. Nor can He be given any name, since we cannot assert anything about Him. We refer to Him only as best we can. In our uncertainty we say, “What does He not feel? is He not self-conscious? does He not know Himself?” Then we must reflect that by speaking thus we are thinking of things, that are opposed to Him of whom we are now thinking. When we suppose that He can be known, or that He possesses self-consciousness, we are already making Him manifold. Were we to attribute to Him thought, it would appear that He needed this thought. If we imagine thought as being within Him, thought seems to be superfluous. For of what does thought consist? Of the consciousness of the totality formed by the two terms that contribute to the act of thought, and which fuse therein. That is thinking oneself, and thinking oneself is real thinking; for each of the two elements of thought is itself an unity to which nothing is lacking. On the contrary, the thought of objects exterior (to Intelligence) is not perfect, and is not true thought. That which is supremely simple and supremely absolute stands in need of nothing. The absolute that occupies the second rank needs itself, and, consequently, needs to think itself. Indeed, since Intelligence needs something relatively to itself, it succeeds in satisfying this need, and consequently, in being absolute, only by possessing itself entirely. It suffices itself only by uniting all the elements constituting its nature (“being”), only by dwelling within itself, only by remaining turned towards itself while thinking; for consciousness is the sensation of manifoldness, as is indicated by the etymology of the word “con-scious-ness,” or, “conscience.” If supreme Thought occur by the conversion of Intelligence towards itself, it evidently is manifold. Even if it said no more than “I am existence,” Intelligence would say it as if making a discovery, and Intelligence would be right, because existence is manifold. Even though it should apply itself to something simple, and should say, “I am existence,” this would not imply successful grasp of itself or existence. Indeed, when Intelligence speaks of existence in conformity with reality, intelligence does not speak of it as of a stone, but, merely, in a single word expresses something manifold. The existence that really and essentially deserves the name of existence, instead of having of it only a trace which would not be existence, and which would be only an image of it, such existence is a multiple entity. Will not each one of the elements of this multiple entity be thought? No doubt you will not be able to think it if you take it alone and separated from the others; but existence itself is in itself something manifold. Whatever object you name, it possesses existence. Consequently, He who is supremely simple cannot think Himself; if He did, He would be somewhere, (which is not the case). Therefore He does not think, and He cannot be grasped by thought. [Ennead V,3 (49) 13]

How do Guardians participate in matter, and of what matter are they formed? This their matter is not corporeal, otherwise they would be animals with sensation. In fact, whether they have aerial or fire-like bodies, they must have had a nature primitively different (from pure Intelligence) to have ultimately united each with his own body, for that which is entirely pure could not have immediately united with a body, although many philosophers think that the being of every Guardian, as guardian, is united to an air-like or fire-like body. But why is the being of every Guardian mingled with a body, while the being of every deity is pure, unless in the first case there be a cause which produces the mingling (with matter)? This cause must be the existence of an intelligible matter, so that whatever participates in it might, by its means, come to unite with sense-matter. [Ennead III,5 (50) 6]

Just as much as the soul, matter is included within the order of beings. For both, so to speak, there is but a single locality; for it would be an error to imagine two different localities, one for matter, and the other for the soul; such as, for instance, earth might be for matter, and air for the soul. The expression that “soul occupies a locality different from matter” means only that the soul is not in matter; that is, that the soul is not united to matter; that the soul does not together with matter constitute something unitary; and that for the soul matter is not a substrate that could contain the soul. That is how the soul is separated from matter. But the soul possesses several powers, since she contains the principle (intelligence), the medium (the discursive reason), and the goal (the power of sensation) (united to the generative and growing powers). Now, just like the beggar who presents himself at the door of the banquet-hall, and with importunity asks to be admitted, matter tries to penetrate into the place occupied by the soul. But every place is sacred, because nothing in it is deprived of the presence of the soul. Matter, on exposing itself to its rays is illuminated by it, but it cannot harbor the principle that illuminates her (the soul). The latter indeed, does not sustain matter, although she be present, and does not even see it, because it is evil. Matter obscures, weakens the light that shines down upon her, by mingling its darkness with her. To the soul, matter affords the opportunity of producing generation, by clearing free access towards matter; for if matter were not present, the soul would not approach it. The fall of the soul is, therefore, a descent into matter; hence comes her “weakness,” which means, that not all of the soul’s faculties are exercised; because matter hinders their action, intruding on the place occupied by the soul and forcing her, so to speak, to retrench. Until the soul can manage to accomplish her return into the intelligible world, matter degrades what it has succeeded in abstracting from the soul. For the soul, therefore, matter is a cause of weakness and vice. Therefore, by herself, the soul is primitively evil, and is the first evil. By its presence, matter is the cause of the soul’s exerting her generative powers, and being thus led to suffering; it is matter that causes the soul to enter into dealings with matter, and thus to become evil. The soul, indeed, would never have approached matter unless the latter’s presence had not afforded the soul an opportunity to produce generation. [Ennead I,8 (51) 14]

A being that were so unreceptive to anything external would have no ground for fear of anything external. Fear might indeed be natural to something. Neither would she be bold, for this sentiment, implies shelter from what is terrifying. As to such desires which are satisfied by the emptying or filling of the body, they belong only to some nature foreign enough to be emptied or filled. How could she participate in a mixture, inasmuch as the essential is unmingled? Further she would not wish to have anything introduced (in herself), for this would imply striving to become something foreign to herself. She would also be far from suffering, for how could she grieve, and about what? For that which is of simple being is self-sufficient, in that she remains in her own being. Neither will she rejoice at any increase, as not even the good could happen to her. What she is, she ever will be. Nor could we attribute to the pure soul sensation, ratiocination or opinion; for sensation is the perception, of a form or of an impassible body; and besides ratiocination and opinion (depend) on sensation. We shall, however, have to examine whether or no we should attribute to the soul thought; also, whether pure pleasure can affect a soul while she remains alone. [Ennead I,1 (53) 2]

Whether the soul, according to her being, be located in the body, above or within this latter, the soul forms with the body an entity called (a “living being” or) organism. In this case, the soul using the body as a tool is not forced to participate in its passions, any more than workmen participate in the experiences of their tools. As to sensations, of course, the soul must perceive them, since in order to use her instrument, the soul must, by means of sensation, cognize the modifications that this instrument may receive from without. Thus seeing consists of using the eyes; and the soul at the same time feels the evils which may affect the sight. Similar is the case with griefs, pains and any corporeal exigency; also with the desires which arise from the soul’s need to take recourse to the ministry of the body. But how do passions from the body penetrate into the soul? For a body could communicate her own properties to some other body; but how could she do so to a soul? [Ennead I,1 (53) 3]

Now let us suppose the soul is mingled with the body. In this mixture, the worse part, or body, will gain, while the soul will lose. The body will improve by participation with the soul; and the soul will deteriorate by association with death and irrationality. Well, does the soul, in somewhat losing life, gain the accession of sensation? On the other hand, would not the body, by participation in life, gain sensation and its derived passions? It is the latter, then, which will desire, inasmuch as it will enjoy the desired objects, and will feel fear about them. It is the latter which may be exposed to the escape of the objects of its desire, and to decay. [Ennead I,1 (53) 4]

We shall later on consider the organized body; here we must find how the conjunction of soul and body could experience suffering. The theory that the affection of the body modifies it so as to produce a sensation which itself would end in the soul, leaves unexplained the origin of sensation. To the theory that suffering has its principle in this opinion or judgment, that a misfortune is happening to ourselves or some one related to us, whence results disagreeable emotion first in the body, and then in the whole living organism, there is this objection, that it is yet uncertain to which opinion belongs; to the soul, or to the conjunction of soul and body. Besides, the opinion of the presence of an evil does not always entail suffering; it is possible that, in spite of such an opinion, one feels no affliction; as, for instance, one may not become irritated at believing oneself scorned; or in experiencing no desire even in the expectation of some good. [Ennead I,1 (53) 5]

It would, however, probably be better to put the matter thus: by their presence, the faculties of the soul cause reaction in the organs which possess them, so that while they themselves remain unmoved, they give them the power to enter into movement. In this case, however, when the living organism experiences suffering, the life-imparting cause must itself remain impassible, while the passions and energies belong wholly to that which receives life. In this case, therefore, the life will not belong exclusively to the soul, but to the conjunction of the soul and body; or, at least, the latter’s life will not be identical with the soul’s, nor will it be the faculty of sensation, which will feel, but the being in whom that faculty inheres. [Ennead I,1 (53) 6]

If, however, sensation, which is no more than a corporeal emotion, finds its term in the soul, the soul must surely feel sensation; therefore it does not occur as an effect of the presence of the faculty of sensation, for this ignores the feeling agent back of it. Nor is it the conjunction of soul and body, for unless the faculty of sensation operate, that aggregate could not feel, and it would then no longer include as elements either the soul, or the faculty of sensation. [Ennead I,1 (53) 6]

The aggregate results from the presence of the soul, not indeed that the soul enters into the aggregate, or constitutes one of its elements. Out of this organized body, and of a kind of light furnished by herself, the soul forms the animal nature, which differs both from soul and body, and to which belongs sensation, as well as all the passions attributed to the animal. 296 [Ennead I,1 (53) 7]

As to the faculty of sensation which is peculiar to the soul, it cannot be the power of perceiving the sense-objects themselves, but only their typical forms, impressed on the animal by sensation. These have already somewhat of the intelligible nature; the exterior sensation peculiar to the animal is only the image of the sensation peculiar to the soul; which, by its very essence is truer and more real, since it consists only in contemplating images while remaining impassible. Ratiocination, opinion and thought, which principally constitute us, deal exclusively with these images, by which the soul has the power of directing the organism. [Ennead I,1 (53) 7]

She seems to be present in the bodies, and illuminates them, making living beings out of them. This occurs not as a mixture of herself and bodies, but by remaining individual, giving out images of herself, just as a single face in several mirrors. Of these, the first is sensation, which resides in the common part, the organism; then come all the other forms of the soul-forms which successively derive each from the other, down to the faculties of generation and increase, and generally, the power of producing and fashioning that which is different from self — which indeed the soul does as soon as she turns towards the object she fashions. [Ennead I,1 (53) 8]

In this conception of the soul, she will be foreign to the cause of the evils which the man does and suffers. These refer to the organism, that common part, understood as above. Although opinion be deceptive, and makes us commit much evil, and although opinion and ratiocination both belong to the soul, yet the soul may be sinless, inasmuch as we are only mastered by the worse part of our nature. Often, indeed, we yield to appetite, to anger, and we are the dupes of some imperfect image. The conception of false things, the imagination does not await the judgment of discursive reason. There are still other cases where we yield to the lower part of ourselves; in sensation, for instance, we see things that do not exist, because we rely on the common sensation of soul and body, before having discerned its objects by discursive reason. [Ennead I,1 (53) 9]

We have distinguished from things common to soul and body, those peculiar to the soul. The former are corporeal, and cannot be produced without the organs, while the latter’s occurrence is independent of the body. Ratiocination is the essential and constitutive faculty of the real soul, because it determines the typical forms derived from sensation, it looks, it somehow feels the images, and really is the dominating part of the soul. The conception of true things is the act of intuitive thoughts. [Ennead I,1 (53) 9]

We might define the animating principle of animals. If it be true, according to common opinion, that animal bodies contain human souls that have sinned, the separable part of these souls does not properly belong to these bodies; although these souls assist these bodies, the souls are not actually present to them. In them the sensation is common to the image of the soul and to the body; — but to the latter only in so far as it is organized and fashioned by the image of the soul. As to the animals into whose bodies no human soul entered, they are produced by an illumination of the universal Soul. [Ennead I,1 (53) 10]
