Intelligence, therefore, essentially constitutes all beings; and when Intelligence thinks them, they are not outside of Intelligence, and neither precede nor follow it. Intelligence is the first legislator, or rather, it is the very law of existence. Parmenides therefore was right in saying, “Thought is identical with existence.” The knowledge of immaterial things is therefore identical with those things themselves. That is why I recognize myself as a being, and why I have reminiscences of intelligible entities. Indeed, none of those beings is outside of Intelligence, nor is contained in any location; all of them subsist in themselves as immutable and indestructible. That is why they really are beings. If they were born, or perished, they would possess existence only in an incidental manner, they would no longer be beings; it would be the existence they possessed which would be essence. It is only by participation that sense-things are what they are said to be; the nature that constitutes their substance derives its shape from elsewhere, as the metal receives its shape from the sculptor, and wood from the carpenter; while the image of art penetrates into the matter, the art itself remains in its identity, and within itself possesses the genuine existence of the statue or of the bed. That is how the bodies’ general necessity of participating in images shows that they are different from the beings; for they change, while the entities are immutable, possess within themselves their own foundation, and have no need of existing in any location, since they have no extension, and since they subsist in an intellectual and absolute existence. Again, the existence of the bodies needs to be guarded by some other principle, while intelligence, which furnishes the existence for objects in themselves perishable, has need of nothing to make itself subsist. [Ennead V,9 (5) 5]
Is “essence” something different from “being”? Does essence indicate an abstraction of the other (four categories), and is being, on the contrary, essence with the other (four categories), motion and rest, identity and difference? Are these the elements of being? Yes: “being” is the totality of these things, of which one is essence, the other is motion, and so forth. Motion, therefore, is accidental essence. Is it also accidental “being?” Or is it being completely? Motion is being, because all intelligible things are beings. But why is not each of the sense-things a being? The reason is, that on high all things form only a single group of totality, while here below they are distinct one from another because they are images that have been distinguished. Likewise, in a seminal (reason), all things are together, and each of them is all the others; the hand is not distinct from the head; while, on the contrary, in a body all the organs are separate, because they are images instead of being genuine beings. [Ennead II,6 (17) 1]
Is the intelligible (Being) then so varied and manifold? It is indeed varied, but it is simultaneously simple; it is both one and manifold; for reason (which is the essence of the universal Soul), is both one and manifold. The universal (Being) is also one; though any difference in it (in this sense, that it contains different essences), results from its own constitution; the difference inheres in its nature, for it could not belong to non-being. The constitution of Essence is such as to be inseparable from unity; unity is present wherever essence is, and the one Essence subsists in itself. It is indeed possible that an essence which in a certain respect is separated from another essence, is, however, entirely present with it. But there are different kinds of presence; first, when sense-things are present with intelligible things, at least to those to which they can be present; second, when intelligible entities are present to each other; likewise, when the body is present to the soul; another, when a science is present to the soul; further, when a science is present to another science, and both coexist in the same intelligence; last, when a body is present to another body. [Ennead VI,4 (22) 11]
If this be so, what opinion shall we form of matter? How can it be the matter of beings? Because matter potentially constitutes the beings. But, since matter already exists potentially, may we not already say that it exists, when we consider what it is to be? The being of matter is only what is to be; it consists of what is going to be; therefore matter exists potentially; but it is potentially not any determinate thing, but all things. Therefore, being nothing by itself, and being what it is, namely, matter, it is nothing actually. If it were something actually, what it would actually be would not be matter; consequently, matter would no longer be absolutely matter; it would be matter only relatively, like metal. Matter is, therefore, non-being; it is not something which merely differs from being, like movement, which relates to matter because it proceeds from matter, and operates in it. Matter is denuded and despoiled of all properties; it can not transform itself, it remains ever what it was at the beginning, non-being. From the very being it actually was no being, since it had withdrawn from all beings, and had never even become any of them; for never was it able to keep a reflection of the beings whose forms it ever aspired to assume. Its permanent condition is to trend towards something else, to exist potentially in respect of the things that are to follow. As it appears where ends the order of intelligible beings, and as it is contained by the sense-beings which are begotten after it, it is their last degree. Being contained in both intelligible and sense-things, it does not actually exist in respect of either of these classes of beings. It exists only potentially; it limits itself to being a feeble and obscure image, which can not assume any form. May we not thence conclude that matter is the image actually; and consequently, is actually deception? Yes, it truly is deception, that is, it is essentially non-being. If then matter actually be non-being, it is the highest degree of non-being, and thus again essentially is non-being. Since non-being is its real nature, it is, therefore, far removed from actually being any kind of a being. If it must at all be, it must actually be non-being, so that, far from real-being, its “being” (so to speak) consists in non-being. To remove the deception of deceptive beings, is to remove their “being.” To introduce actuality in the things which possess being and essence potentially, is to annihilate their reason for being, because their being consists in existing potentially. [Ennead V,5 (25) 5]
If theory belong to imagination, and if both the rational and irrational souls possess memory, we will have two kinds of imagination (intellectual and sensual); and if both souls are separate, each of them will possess one kind of imagination. The theory of two kinds of imagination within us in the same principle would not account for there being two kinds of imagination; and it would leave unsolved the question to which of them memory belongs. If memory belong to both kinds of imagination, there will always be two kinds of imagination — for it cannot be said that the memory of intelligible things belongs to the one, and that of sense-things to the other; otherwise we would have two animate beings with nothing in common. If then memory equally belong to both imaginations, what difference is there between them? Besides, why do we not notice this difference? Here is the cause. [Ennead IV,3 (27) 31]
When the soul departs from the intelligible world; when instead of continuing to form a unity with it, she wishes to become independent, to become distinct, and to belong to herself; when she inclines towards the things here below, then she remembers herself. The memory of intelligible things hinders her from falling, that of terrestrial things makes her descend here below, and that of celestial things makes her dwell in heaven. In general, the soul is and becomes what she remembers. Indeed, to remember is to think or imagine; now, to imagine is not indeed to possess a thing, but to see it and to conform to it. If the soul see sense-things, by the very act of looking at them she somehow acquires some extension. As she is things other than herself only secondarily, she is none of them perfectly. Placed and established on the confines of the sense and intelligible worlds, she may equally move towards either. [Ennead IV,4 (28) 3]
What is the origin of the cause of what is a form, which is characteristic of Intelligence? It is not from Intelligence, because the form is not separable from Intelligence, combining with it to form one single and same thing. If then Intelligence possess the forms in their fulness, this fulness of forms implies that they contain their cause. Intelligence contains the cause of each of the forms it contains. It consists of all these forms taken together, or separately. None of them needs discovery of the cause of its production, for simultaneously with its production, it has contained the cause of its hypostatic existence. As it was not produced by chance, it contains all that belongs to its cause; consequently, it also possesses the whole perfection of its cause. Sense-things which participate in form do not only receive their nature from it, but also the cause of this nature. If all the things of which this universe is composed be intimately concatenated; and if the universe, containing all things, also contain the cause of each of them; if its relation with them be the same as that of the body with its organs, which do not mature successively, but which, towards each other, are mutually related as cause and effect; so much the more, in the intelligible world, must things have their “causes,” all of them in general in respect to the totality, and each independently in respect to itself. [Ennead VI,7 (38) 2]
But there are some (Aristotelians or Peripatetics) who might think that the intelligible Man and the sense-man form but one. Let us first discuss this point. Does the sense-man have a being different from the soul which produces him, and makes him live and reason? Is he the soul that is disposed in some special manner? Is he the soul that uses the body in some particular way? If man be a reasonable living organism, and if the latter be composed of soul and body, this definition of man will not be identical with that of the soul. If the man be defined as being the composite of the reasonable soul and the body, how can he be an immortal hypostatic existence? This definition suits the sense-man only from the moment that the union of the soul and the body has occurred; it expresses what will be, instead of setting forth what we call the Man-in-himself; rather than being a real determination of his characteristics, it would be only a description which would not reveal the original being. Instead of defining form engaged in matter, it indicates what is the composite of soul and body, after the union has occurred. In this case, we do not yet know what is man considered in his being, which is intelligible. To the claim that the definition of sense-things should express something composite, it might be answered, that we do acknowledge that we must not determine the consistence of each thing. Now if it be absolutely necessary to define the forms engaged in matter, we must also define the being that constitutes the man; that is necessary especially for those (Peripateticians) who, by a definition, mean a statement of a being’s original “characteristics.” [Ennead VI,7 (38) 4]
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]
(Now let us pass to the other question we asked). How does it happen that all the Animals who, like the Horse itself, are contained in divine Intelligence, do not incline towards the things here below (by generating them)? Doubtless, to beget a horse, or any other animal here below, divine Intelligence must hold its conception; nevertheless it must not be believed that it first had the volition of producing the horse, and only later its conception. Evidently, it could not have wished to produce the horse, but because it already had the conception thereof; and it could not have had the conception thereof but because it had to produce the horse. Consequently, the Horse who was not begotten preceded the horse who later was to be begotten. Since the first Horse has been anterior to all generation, and was not conceived to be begotten, it is not because the divine Intelligence inclines towards the things here below, nor because it produces them, that it contains the intelligible Horse and the other beings. The intelligible entities existed already in Intelligence (before it begat) and the sense-things were later begotten by necessary consequence; for it was impossible that the procession should cease with the intelligibles. Who indeed could have stopped this power of the (Intelligence) which is capable of simultaneous procession, and of remaining within itself? [Ennead VI,7 (38) 8]
Can the qualities seen in the sense-world, and those that exist in the intelligible world, be classified together in one kind? This question demands an answer from those who claim that there are also qualities in the intelligible world. Should it also be asked of those who do not admit of the existence on high of kinds, but who limit themselves to attributing some habit to Intelligence? It is evident that Wisdom exists in Intelligence; if this Wisdom be homonymous (similar in name only) with the wisdom which we know here below, it is not reckoned among sense-things; if, on the contrary it be synonymous (similar in nature also) with the wisdom which we know here below, quality would be found in intelligible entities, as well as in sense-things (which is false); unless indeed it be recognized that all intelligible things are essences, and that thought belongs among them. [Ennead VI,1 (42) 12]
The questions here to be solved are, how unity subsists within essence, how they both divide, and in general how any genera divide; and whether their two divisions be identical, or different. To solve these questions, we shall first have to ask how in general any thing whatever is said to be one, and is one; then, if it can be said in the same sense that essence is one, in what sense this is said. Evidently, unity is not the same for everything. It cannot even be understood in the same sense in respect to sense-things, and intelligible things; not any more than essence is identical for these two order of (beings), or even for sense-things compared to each other. The idea of unity is not the same in reference to a choric ballet, an army, a vessel or a house; it is even less so in respect of one of these things, and when it deals with continuous objects. And nevertheless, by their unity all these things imitate the same archetype, some from far, some from near. Intelligence, surely, is assuredly that which most approaches absolute Unity; for although the soul already possess unity, Intelligence possesses it far more intensely; for it is the one essence. [Ennead VI,2 (43) 11]
If, however, it be further objected, that the other things could not exist without being in matter, we will answer that that is true only for sense-things. But if matter be anterior to sense-things, that does not hinder itself being posterior to many other things, and to all intelligible things; for the existence of matter is far more obscure than the things in matter, if these things be (”seminal) reasons,” which participate deeper in essence, while matter is completely irrational, being an adumbration, and a decay of reason. [Ennead VI,3 (44) 7]
We have already explained that discrete quantity is clearly distinguished from continuous quantity, both by its own definition, and the general definition (for quantity). We may add that numbers are distinguished from each other by being even and odd. If besides there be other differences amidst the even and odd numbers, these differences will have to be referred to the objects in which are the numbers, or to the numbers composed of unities, and not any more to those which exist in sense-beings. If reason separate sense-things from the numbers they contain, nothing hinders us then from attributing to these numbers the same differences (as to the numbers composed of unities).
