Guthrie-Plotinus: notions

Are the notions of virtue, and other intelligible entities by the soul thought eternal, or does virtue arise and perish? If so, by what being, and how will it be formed? It is the same problem that remains to be solved. Intelligible entities must therefore be eternal and immutable, like geometrical notions, and consequently cannot be corporeal. Further, the subject in whom they exist must be of a nature similar to theirs, and therefore not be corporeal; for the nature of body is not to remain immutable, but to be in a perpetual flow. [Ennead IV,7 (2) 8]

For he has ascended to the divinity, and has become assimilated thereto. As purification permits one to know the better things, so the notions we have within us, and which constitute real science, are made clear. Indeed, it is not by an excursion among external objects that the soul attains the intuition of wisdom and virtue, but by re-entering into herself, in thinking herself in her primitive condition. Then she clears up and recognizes in herself the divine statues, soiled by the rust of time. Likewise, if a piece of gold were animated and released itself from the earth by which it was covered, after first having been ignorant of its real nature because it did not see its own splendor, it would admire itself when considering itself in its purity; it would find that it had no need of a borrowed beauty, and would consider itself happy to remain isolated from everything else. [Ennead IV,7 (2) 10]

(17). (The Stoics), indeed, claim that every soul is perishable. In this case, everything should long since have been destroyed. Others might say that our soul were mortal, while the universal Soul were immortal. On them, however, is the burden of proof of a difference between the individual and universal souls. Both of them, indeed, are a principle of movement; both live by themselves; both grasp the same object by the same faculty, either by thinking the things contained in heaven, or by considering the nature (“being”) of each being, ascending unto the first principle. Since our soul thinks absolute essences either by the notions she finds within herself, or by reminiscence, she evidently is prior to the body. Possessing knowledge of eternal entities, she herself must be eternal. All that dissolves, existing only by its compositeness, can naturally dissolve in the same manner that it became composite. But the soul is a single, simple actualization, whose essence is life; not in this manner therefore can the soul perish. Neither could the soul perish by division into a number of parts; for, as we have shown, the soul is neither a mass nor a quantity. As little could the soul perish by alteration; for when alteration destroys anything, it may remove its form, but leaves its matter; alteration, therefore, is a characteristic of something composite. Consequently as the soul cannot perish in any of these ways, she is imperishable. [Ennead IV,7 (2) 12]

The scientific notions that the soul forms of sense-objects, by discursive reason, and which should rather be called opinions, are posterior to the objects (they deal with); and consequently, are no more than images of them. But true scientific notions received from intelligence by discursive reasons do not contain any sense-conceptions. So far as they are scientific notions, they are the very things of which they are the conceptions; they reveal the intimate union of intelligence and thought. Interior Intelligence, which consists of the primary (natures) possesses itself intimately, resides within itself since all eternity, and is an actualization. It does not direct its glances outside of itself, because it possesses everything within itself; it does not acquire, and does not reason to discover things that may not be present to them. Those are operations characteristic of the soul. Intelligence, remaining fixed within itself, is all things simultaneously. Nevertheless, it is not thought which makes each of them subsist; it is only because intelligence thought the divinity or movement, for instance, that the divinity or movement exists. When we say that thoughts are forms, we are mistaken if thereby we mean that the intelligible exists only because Intelligence thinks it. On the contrary, it is only because the intelligible exists, that Intelligence can think. Otherwise, how would Intelligence come to think the intelligible? It cannot meet the intelligible by chance, nor waste itself in fruitless efforts. [Ennead V,9 (5) 7]

Since the thought is something essentially one (?), the form, which is the object of thought, and the idea, are one and the same thing. Which is this thing? Intelligence and the intellectual “being,” for no idea is foreign to intelligence; each form is intelligence, and the whole intelligence is all the forms; every particular form is a particular intelligence. Likewise science, taken in its totality, is all the notions it embraces; every notion is a part of the total science; it is not separated from the science locally, and exists potentially in the whole science. Intelligence resides within itself, and by possessing itself calmly, is the eternal fulness of all things. If we conceived it as being prior to essence, we would have to say that it was the action and thought of Intelligence which produced and begat all beings. But as, on the contrary, it is certain that essence is prior to Intelligence, we should, within the thinking principle, first conceive the beings, then actualization and thought, just as (the nature) of fire is joined by the actualization of the fire, so that beings have innate intelligence as their actualization. Now essence is an actualization; therefore essence and intelligence are but a single actualization, or rather both of them fuse. Consequently, they form but a single nature, as beings, the actualization of essence, and intelligence. In this case the thought is the form, and the shape is the actualization of the being. When, however, in thought we separate essence from Intelligence, we must conceive one of these principles as prior to the other. The Intelligence which operates this separation is indeed different from the essence from which it separates; but the Intelligence which is inseparable from essence and which does not separate thought from essence is itself essence and all things. [Ennead V,9 (5) 8]

It may be objected that in science a part is not the total science. Doubtless, the notion which is actualized, and which is studied to the exclusion of others, because there is special need of it, is only partially an actualization. Nevertheless, in a latent manner it potentially comprises all the other notions it implies. Thus, all the notions are contained in each part of the science, and in this respect each part is the total science; for what is only partially actualized (potentially) comprises all the notions of science. Each notion that one wishes to render explicit is at one’s disposition; and this in every part of the science that is considered; but if it be compared with the whole science, it seems to be there only potentially. It must not, however, be thought that the particular notion does not contain anything of the other notions; in this case, there would be nothing systematic or scientific about it; it would be nothing more than a sterile conception. Being a really scientific notion, it potentially contains all the notions of the science; and the genuine scientist knows how to discover all its notions in a single one, and how to develop its consequences. The geometrical expert shows in his demonstrations how each theorem contains all the preceding ones, to which he harks back by analysis, and how each theorem leads to all the following ones, by deduction. [Ennead IV,9 (8) 5]

Such as imagine that beings are governed by luck or chance, and that they depend on material causes are far removed from the divinity, and from the conception of unity. It is not such men that we are addressing, but such as admit the existence of a nature different from the corporeal one, and who at least rise (to an acknowledgment of the existence of) the Soul. These should apply themselves to the study of the nature of the soul, learning, among other truths, that she proceeds from Intelligence, and that she can achieve virtue by participating in Intelligence through reason. They must then acknowledge the existence of an Intelligence superior to the intelligence that reasons, namely, to discursive reason. They must (also realize) that reasonings imply an interval (between notions), and a movement (by which the soul bridges this interval). They must be brought to see that scientific knowledge consists also of reasons of the same nature (namely, rational notions), reasons suitable to the soul, but which have become clear, because the soul has received the succession of intelligence which is the source of scientific knowledge. By intelligence (which belongs to her), the soul sees the divine Intellect, which to it seems sensual, in this sense that it is perceptible by intelligence, which dominates the soul, and is her father; that is, the intelligible world, a calm intellect which vibrates without issuing from its tranquility, which contains everything, and which is all. It is both definite and indefinite manifoldness, for the ideas it contains are not distinct like the reasons (the rational notions), which are conceived one by one. Nevertheless, they do not become confused. Each of them becomes distinct from the others, just as in a science all the notions, though forming an indivisible whole, yet each has its own separate individual existence. This multitude of ideas taken together constitutes the intelligible world. This is the (entity) nearest to the First. Its existence is inevitably demonstrated by reason, as much as the necessity of the existence of the Soul herself; but though the intelligible world is something superior to the Soul, it is nevertheless not yet the First, because it is neither one, nor simple, while the one, the principle of all beings, is perfectly simple. [Ennead VI,9 (9) 5]

Besides, the intelligible world has much more unity than the sense-world; otherwise, there would be two sense-worlds, since the intelligible sphere would not differ from the sense-sphere if the former did not have more unity than the latter. In respect to unity, therefore, the intelligible world would surpass the sense-sphere. It would indeed be ridiculous to admit that one of the two spheres would have an extension suitable to its nature; while the other, without any necessity, would extend, and would withdraw from its centre. Why would not all things conspire together to unity, in the intelligible world? There, indeed, no one thing hinders another by impenetrability, any more than the conception that you have of a notion or of a proposition in no wise hinders the one that I have in myself, any more than different notions mutually hinder each other in the same soul. To the objection that such a union could not take place for (separate) beings, an affirmative answer may be given, but only if one dare to suppose that veritable beings are corporeal masses. [Ennead VI,5 (23) 10]

Further, the soul’s appetite is intemperate when it alone is active; for then, in the absence of the principles that ought to command or direct her, it alone does everything. Besides, the rational part, whose function it is to see (by considering the notions it receives from intelligence), is occupied with something else, for it does not do everything simultaneously, being busy with some other action; it considers other than corporeal things, so far as it can. Perhaps also the virtue or vice of the appetite depend considerably on the good or evil condition of the organs; so that, in either case, nothing is added to the soul. [Ennead III,6 (26) 2]

(According to Aristotle  ), it is absolutely necessary that what can be affected must have powers and qualities opposed to the things that approach it, and affect it. Thus, it is the cold that alters the heat of an object, and humidity that alters its dryness, and we say that the substrate is altered, when it ceases being hot, and grows cold; and ceasing to be dry, becomes humid. Another proof of this truth is the destruction of the fire that, by changing, becomes another element. Then we say that it is the fire, but not the matter that has been destroyed. What is affected is therefore that which is destroyed; for it is always a passive modification that occasions destruction. Consequently being destroyed and being affected are inseparable notions. Now it is impossible for matter to be destroyed; for how could it be destroyed, and in what would it change? [Ennead III,6 (26) 8]

It (may be objected) that nothing hinders Intelligence from knowing the changes of other beings, such as, for instance, the periodical revolutions of the world, without itself undergoing any change. But then it would have to follow the changes of the moving object, as it would think first of one thing, and then of another. Besides, thought is something else than memory, and we must not apply to self-consciousness the name of memory. Indeed, intelligence does not busy itself with retaining its thoughts, and with hindering them from escaping; otherwise it might also fear lest it lose its own nature (“Being”). For the soul herself, remembering is not the same as recalling innate notions. When the soul has descended here below, she may possess these notions without thinking of them, especially if it be only recently that she entered into the body. The ancient philosophers seem to have applied the terms memory and reminiscence to the actualization by which the soul thinks of the entities she possesses; that (however) is a quite special kind of memory, entirely independent of time. [Ennead IV,3 (27) 25]

Can memory be referred to sensibility? Is the faculty that feels also the one that remembers? But if the image of the soul (the irrational soul) possess the memory, as we said above, there would be in us two faculties that will feel. Further, if sensibility be capable of grasping notions, it will also have to perceive the conceptions of discursive reason, or it will be another faculty that will perceive both. [Ennead IV,3 (27) 29]

Are our notions of intellectual entities actualized by the potentiality which constitutes memory? If these notions be not intuitions, it is by memory that they become actualized; if they are intuitions, it is by the potentiality which has given them to us on high. This power awakes in us every time that we rise to intelligible things, in it is that which sees what we later talk about. We do not perceive intelligible entities by imagination or reasoning, which itself is forced to draw its principles from elsewhere; it is by our faculty of contemplation, which alone enables us to speak of them while we are here below. We see them by awaking in ourselves here below the same potentiality which we are to arouse when we are in the intelligible world. We resemble a man who, climbing the peak of a rock, should, by his glance, discover objects invisible for those who have not climbed with him. [Ennead IV,4 (28) 5]

The principle which presides over the order of the universe is double; from one point of view he is the demiurge; from the other, the universal Soul. By the name of Jupiter, therefore, we designate both the demiurge, and the “Governor of the universe.” As to the demiurge, we must dismiss all notions of past or future, and attribute to him nothing but a life that is uniform, immutable, and independent, of time. But the life of the governor of the universe (which is the universal Soul), raises the question whether she be also free from any necessity of reasoning, and of planning what is to be done? Surely, for the order which is to rule has already been devised and decided, and that without having been ordered; for that which is in order was that which became, and the process of becoming eventuates in order. The latter is the activity of the Soul which depends from an abiding wisdom, a wisdom whose image is the order existing within the soul. As the wisdom contemplated by the soul does not change, neither does its action. Indeed, the Soul contemplates wisdom perpetually; if she ceased, she would lapse into incertitude, for the soul is as unitary as her work. This unitary principle that governs the world dominates perpetually, and not only occasionally; for whence should there be several powers, to struggle among each other, or get into uncertainties? The principle that administers the universe is therefore unitary, and ever wills the same. Why, indeed, should she desire now one thing, and then another, and thus involve herself in uncertainties? Still, even if she altered herself under unitary conditions, she would not be involved in difficulties. That the universe contains a great number and kinds of parts opposed to each other is no reason that the Soul does not with certainty know how to arrange them. She does not begin by objects of lowest rank, nor by parts; she directs by the principles. Starting from these, she easily succeeds in putting everything in order. She dominates because she persists in a single and identical function. What would induce her to wish first one thing, and then another? Besides, in such a state of affairs, she would hesitate about what she ought to do, and her action would be weakened, and this would result in a weakness of her activities, while deliberating about still undecided plans. [Ennead IV,4 (28) 10]

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]

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

But, in order that this truth may appear in its full light, we shall first have to clear away all the other opinions, and especially have to refute the teaching opposite to ours. This is the question asked of us: “What will be the fruit gathered by him who has the intelligence necessary to acquire one of these goods (such as existence and life), if on hearing them named, he be not impressed thereby, because he does not understand them, either because they seem to him no more than words, or because his conception of each of these things should differ (from our view of them), or because in his search for the Good he seeks some sense-object, such as wealth, or the like?” The person who thus scorns these things (existence and life), thereby implicitly recognizes that there is within him a certain good, but that, without knowing in what it consists, he nevertheless values these things according to his own notion of the Good; for it is impossible to say, “that is not the good,” without having some sort of knowledge of the good, or acquaintance therewith. The above speaker seems to betray a suspicion that the Good in itself is above Intelligence. Besides, if in considering the Good in itself, or the good which most approaches it, he do not discern it, he will nevertheless succeed in getting a conception of it by its contraries; otherwise, he would not even know that the lack of intelligence is an evil, though every man desire to be intelligent, and glory in being such, as is seen by the sensations which aspire to become notions. If intelligence, and especially primary Intelligence, be beautiful and venerable, what admiration might not then be felt by him who could contemplate the generating principle, the Father of Intelligence? Consequently, he who affects to scorn existence and life receives a refutation from himself and from all the affections he feels. They who are disgusted of life are those who consider not the true life, but the life which is mingled with death. [Ennead VI,7 (38) 29]

Consequently, the Good does not think itself either as good, nor as anything else; for it possesses nothing different from itself. It only has “a simple perception of itself in respect to itself”; but as there is no distance or difference in this perception it has of itself, what could this perception be but itself? That is why it perceives a difference where being and intelligence appear. In order to think, intelligence must admit identity and difference simultaneously. On the one hand, without the relation between the Intelligible and itself, the (mind) will not distinguish itself from (the intelligible); and on the other, without the arising of an “otherness” which would enable it to be everything, it would not contemplate all (earthly) entities. (Without this difference), intelligence would not even be a “pair.” Then, since intelligence thinks, if it think really, it will not think itself alone, for why should it not think all things? (Would it not do so) because it was impotent to do so? In short, the principle which thinks itself ceases to be simple, because in thinking itself it must think itself as something different, which is the necessary condition of thinking itself. We have already said that intelligence cannot think itself without contemplating itself as something different. Now in thinking, intelligence becomes manifold (that is, fourfold): intelligible object (thing thought) and intelligent subject (thinker); movement (or, moved), and everything else that belongs to intelligence. Besides, it must be noticed, as we have pointed out elsewhere, that, to be thought, any thought, must offer variety; but (in the divinity) this movement is so simple and identical that it may be compared to some sort of touch, and partakes in nothing of intellectual actualization (therefore, thought cannot be attributed to the divinity). What? Will (the divinity) know neither others nor Himself, and will He remain immovable in His majesty? (Surely). All things are posterior to Him; He was what He is before them. The thought of these things is adventitious, changeable, and does not apply to permanent objects. Even if it did apply to permanent objects, it would still be multiple, for we could not grant that in inferior beings thought was joined to being, while the thoughts of intelligence would be empty notions. The existence of Providence is sufficiently accounted for by its being that from which proceed all (beings). How then (in regard to all the beings that refer to Him) could (the divinity) think them, since He does not even think Himself, but remains immovable in His majesty? That is why Plato, speaking of “being,” says that it doubtless thinks, but that it does not remain immovable in its majesty. By that he means that, no doubt, “being” thinks, but that that which does not think remains immovable in its majesty; using this expression for lack of a better one. Thus Plato considers the Principle which is superior to thought as possessing more majesty, nay, sovereign majesty. [Ennead VI,7 (38) 39]

What are our thoughts when we inquire whether something depends on us? Under what circumstances do we question this responsibility? We ask ourselves whether we are anything, and whether really anything depends on us when undergoing the buffets of fortune, of necessity, of violent passions that dominate our souls, till we consider ourselves mastered, enslaved, and carried away by them? Therefore we consider as dependent on ourselves what we do without the constraint of circumstances, necessity, or violence of passions — that is, voluntarily, and without an obstacle to our will. Hence the following definition: We are responsible for that which depends on our will, which happens or which is omitted according to our volition. We indeed call voluntary what we unconstrainedly do and consciously. On us depends only that of which we are the masters to do or not to do. These two notions are usually connected, though they differ theoretically. There are cases when one of them is lacking; one might, for instance, have the power to commit a murder; and nevertheless if it were one’s own father that he had ignorantly killed, it would not be a voluntary act. In this case, the action was free, but not voluntary. The voluntariness of an action depends on the knowledge, not only of the details, but also of the total relations of the act. Otherwise, why should killing a friend, without knowing it, be called a voluntary action? Would not the murder be equally involuntary if one did not know that he was to commit it? On the contrary hypothesis, it may be answered that one had been responsible for providing oneself with the necessary information; but nevertheless it is not voluntarily that one is ignorant, or that one was prevented from informing oneself about it. [Ennead VI,8 (39) 1]

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]

The cognition of intelligible things still less admits of an experience or impression; for the soul finds the intelligible things within herself, while it is outside of herself that she contemplates sense-objects. Consequently the soul’s notions of intelligible entities are actualizations of a nature superior to those of sense-objects, being the actualizations of the soul herself, that is, spontaneous actualizations. We shall however have to relegate to another place the question whether the soul sees herself as double, contemplating herself as another object, so to speak, and whether she sees intelligence as single in a manner such that both herself and intelligence seem but one. [Ennead IV,6 (41) 2]

Let us, therefore, suppose that Intelligence was in a state in which it did not yet attach itself to anything in particular, so that it had not yet become an individual intelligence. Let us conceive it similar to knowledge considered by itself before the notions of the particular species, or to the knowledge of a species taken before the notions of the contained parts. Universal Knowledge, without (in actualization) being any particular notion, potentially lies within all notions, and reciprocally, each particular notion is one single thing in actualization, but all things in potentiality; likewise with universal Knowledge. The notions which thus refer to a species exist potentially in universal Knowledge, because, while applying itself to a species, they potentially are also universal Knowledge. Universal Knowledge is predicated of each particular notion, without the particular notion being predicated of universal Knowledge; but universal Knowledge must none the less subsist in itself without blending (with anything else). [Ennead VI,2 (43) 20]

The case is similar with Intelligence. There is a kind of existence of universal Intelligence, which is located above the particular actualized intelligences, and is different from that of the particular intelligences. These are filled with universal notions: universal Intelligence furnishes to the particular intelligences the notions they possess. It is the potentiality of these intelligences all of which it contains in its universality; on their side, these, in their particularity, contain universal Intelligence just as a particular science implies universal science. The great Intelligence exists in itself, and the particular intelligences also exist in themselves; they are implied in universal Intelligence, just as this one is implied in the particular intelligences. Each one of the particular intelligences exists simultaneously in itself, and in something else (in the universal Intelligence), just as universal Intelligence exists simultaneously in itself and in all the others. In universal Intelligence, which exists in itself, all particular intelligences exist potentially, because it actually is all the intelligences, and potentially each of them separately. On the contrary, these are actualizations of the particular intelligences, and potentially universal Intelligence. Indeed, so far as they are what is predicated of them, they are actualizations of what is predicated; so far as they exist in the genus that contains them, they are this genus potentially. Genus, as such, is potentially all the species it embraces; it is none of them in actuality; but all are implied therein. So far as genus is in actualization what exists before the species, it is the actualization of the things which are not particular. As occurs in the species, these particular things achieve such actualization only by the actualization which emanates from the genus, and which, with regard to them, acts as cause. [Ennead VI,2 (43) 20]

A further possibility is that these things should be classified according to their effects, and that it is reasonable to do so with invisible entities, such as sciences; but this would not be applicable to sense-objects. When indeed we divide sciences by their effects, and when, in general, we classify them according to the powers of the soul, by concluding from the diversity of their effects that they differ, our mind grasps the difference of these powers, and it determines not only with what objects they deal, but it also defines their reason (or, essence). Let us admit that it is easy to distinguish arts according to their reasons, and according to the notions they include; but is it possible to divide corporeal qualities in that manner? Even when one studies the intelligible world, there is room for doubt as to how the different reasons distinguish themselves from each other; it is easy enough to see that white differs from black; but in what does it do so? [Ennead VI,3 (44) 17]

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]
