But if Matter is devoid of quality how can it be evil? It is described as being devoid of quality in the sense only that it does not essentially possess any of the qualities which it admits and which enter into it as into a substratum. No one says that it has no nature; and if it has any nature at all, why may not that nature be evil though not in the sense of quality? Quality qualifies something not itself: it is therefore an accidental; it resides in some other object. Matter does not exist in some other object but is the substratum in which the accidental resides. Matter, then, is said to be devoid of Quality in that it does not in itself possess this thing which is by nature an accidental. If, moreover, Quality itself be devoid of Quality, how can Matter, which is the unqualified, be said to have it? Thus, it is quite correct to say at once that Matter is without Quality and that it is evil: it is Evil not in the sense of having Quality but, precisely, in not having it; give it Quality and in its very Evil it would almost be a Form, whereas in Truth it is a Kind contrary to Form. Enneads I,8,
The imaging of Quantity upon Matter by an outside power is not more surprising than the imaging of Quality; Quality is no doubt a Reason-Principle, but Quantity also – being measure, number – is equally so. Enneads II,4,
But this notion reduces all existence to qualified things or qualities: Quantity itself becomes a Quality and so does even Existence. Now this cannot be: if such things as Quantity and Existence are qualified, they are, by that very fact, not qualities: Quality is an addition to them; we must not commit the absurdity of giving the name Quality to something distinguishable from Quality, something therefore that is not Quality. Enneads II,4,
Is it suggested that its mere Alienism is a quality in Matter? If this Alienism is difference-absolute [the abstract entity] it possesses no Quality: absolute Quality cannot be itself a qualified thing. Enneads II,4,
An absence is neither a Quality nor a qualified entity; it is the negation of a Quality or of something else, as noiselessness is the negation of noise and so on. A lack is negative; Quality demands something positive. The distinctive character of Matter is unshape, the lack of qualification and of form; surely then it is absurd to pretend that it has Quality in not being qualified; that is like saying that sizelessness constitutes a certain size. Enneads II,4,
Sixth tractate – Quality and form-idea. Enneads: II VI.
But we must enquire into Quality in itself: to know its nature is certainly the way to settle our general question. Enneads: II VI.
But is not the Form of Quality? No, the Form is not a Quality: it is a Reason-Principle. Enneads: II VI.
Thus: Quality is a condition superadded to a Reality whose existence does not depend upon it, whether this something more be a later acquirement or an accompaniment from the first; it is something in whose absence the Reality would still be complete. It will sometimes come and go, sometimes be inextricably attached, so that there are two forms of Quality, the moveable and the fixed. Enneads: II VI.
What, then, distinguishes Quality in the Intellectual Realm from that here, if both are Acts? The difference is that these [“Quality-Activities”] in the Supreme do not indicate the very nature of the Reality [as do the corresponding Activities here] nor do they indicate variations of substance or of [essential] character; they merely indicate what we think of as Quality but in the Intellectual Realm must still be Activity. Enneads: II VI.
In other words this thing, considered in its aspect as possessing the characteristic property of Reality is by that alone recognised as no mere Quality. But when our reason separates what is distinctive in these [“Quality-Activities”] – not in the sense of abolishing them but rather as taking them to itself and making something new of them – this new something is Quality: reason has, so to speak, appropriated a portion of Reality, that portion manifest to it on the surface. Enneads: II VI.
By this analogy, warmth, as a concomitant of the specific nature of fire, may very well be no quality in fire but an Idea-Form belonging to it, one of its activities, while being merely a Quality in other things than fire: as it is manifested in any warm object, it is not a mode of Reality but merely a trace, a shadow, an image, something that has gone forth from its own Reality – where it was an Act – and in the warm object is a quality. Enneads: II VI.
All, then, that is accident and not Act; all but what is Idea-form of the Reality; all that merely confers pattern; all this is Quality: qualities are characteristics and modes other than those constituting the substratum of a thing. Enneads: II VI.
And; one and the same thing cannot be both Quality and non-quality: the thing void of Real-Existence is Quality; but the thing accompanying Reality is either Form or Activity: there is no longer self-identity when, from having its being in itself, anything comes to be in something else with a fall from its standing as Form and Activity. Enneads: II VI.
Finally, anything which is never Form but always accidental to something else is Quality unmixed and nothing more. Enneads: II VI.
By the conditions of Manifestation, colour rises from non-colour [= from the colourless prototype of colour in the Ideal Realm]. Quality, known by the one name with its parallel in the sphere of Primals, rises, similarly, from non-quality: in precisely the same mode, the Magnitude appearing upon Matter rises from non-Magnitude or from that Primal which is known to us by the same name; so that material things become visible through standing midway between bare underlie and Pure Idea. All is perceptible by virtue of this origin in the Intellectual Sphere but all is falsity since the base in which the manifestation takes place is a non-existent. Enneads III,6,
The Intellectual Kosmos thus a manifold, Number and Quantity arise: Quality is the specific character of each of these ideas which stand as the principles from which all else derives. Enneads: V I
Suppose however that we do possess ourselves of objective truth when in comparing two points of time we pronounce one prior, or posterior, to the other, that priority does entail something distinct from the objects to which it refers; admit an objective truth behind the relation of left and right: does this apply also to magnitudes, and is the relation exhibiting excess and deficiency also something distinct from the quantities involved? Now one thing is double of another quite apart from our speech or thought; one thing possesses and another is possessed before we notice the fact; equals do not await our comparison but – and this applies to Quality as well as Quantity – rest upon an identity existing between the objects compared: in all the conditions in which we assert Relation the mutual relation exists over and above the objects; we perceive it as already existent; our knowledge is directed upon a thing, there to be known – a clear testimony to the reality of Relation. Enneads: VI I
As regards Quality, the source of what we call a “quale,” we must in the first place consider what nature it possesses in accordance with which it produces the “qualia,” and whether, remaining one and the same in virtue of that common ground, it has also differences whereby it produces the variety of species. If there is no common ground and the term Quality involves many connotations, there cannot be a single genus of Quality. Enneads: VI I
What then will be the common ground in habit, disposition, passive quality, figure, shape? In light, thick and lean? If we hold this common ground to be a power adapting itself to the forms of habits, dispositions and physical capacities, a power which gives the possessor whatever capacities he has, we have no plausible explanation of incapacities. Besides, how are figure and the shape of a given thing to be regarded as a power? Moreover, at this, Being will have no power qua Being but only when Quality has been added to it; and the activities of those substances which are activities in the highest degree, will be traceable to Quality, although they are autonomous and owe their essential character to powers wholly their own! Enneads: VI I
Perhaps, however, qualities are conditioned by powers which are posterior to the substances as such [and so do not interfere with their essential activities]. Boxing, for example, is not a power of man qua man; reasoning is: therefore reasoning, on this hypothesis, is not quality but a natural possession of the mature human being; it therefore is called a quality only by analogy. Thus, Quality is a power which adds the property of being qualia to substances already existent. Enneads: VI I
In the first place, Quality is not merely a question of action and passion, involving a simple distinction between the potentially active [quality] and the passive: health, disposition and habit, disease, strength and weakness are also classed as qualities. It follows that the common ground is not power, but something we have still to seek. Enneads: VI I
But if Quality is determined by formation and characteristic and Reason-Principle, how explain the various cases of powerlessness and deformity? Doubtless we must think of Principles imperfectly present, as in the case of deformity. And disease – how does that imply a Reason-Principle? Here, no doubt, we must think of a principle disturbed, the Principle of health. Enneads: VI I
But it is not necessary that all qualities involve a Reason-Principle; it suffices that over and above the various kinds of disposition there exist a common element distinct from Substance, and it is what comes after the substance that constitutes Quality in an object. Enneads: VI I
But if these considerations are sound, why has Quality more than one species? What is the ground for distinguishing between habit and disposition, seeing that no differentia of Quality is involved in permanence and non-permanence? A disposition of any kind is sufficient to constitute a quality; permanence is a mere external addition. It might however be urged that dispositions are but incomplete “forms” – if the term may pass – habits being complete ones. But incomplete, they are not qualities; if already qualities, the permanence is an external addition. Enneads: VI I
Another point: why is natural ability to be distinguished from that acquired by learning? Surely, if both are qualities, they cannot be differentiae of Quality: gained by practice or given in nature, it is the same ability; the differentia will be external to Quality; it cannot be deduced from the Ideal Form of boxing. Whether some qualities as distinguished from others are derived from experience is immaterial; the source of the quality makes no difference – none, I mean, pointing to variations and differences of Quality. Enneads: VI I
A further question would seem to be involved: If certain qualities are derived from experience but here is a discrepancy in the manner and source of the experience, how are they to be included in the same species? And again, if some create the experience, others are created by it, the term Quality as applied to both classes will be equivocal. Enneads: VI I
If then we do not propose to divide Quality in this [fourfold] manner, what basis of division have we? We must examine whether qualities may not prove to be divisible on the principle that some belong to the body and others to the soul. Those of the body would be subdivided according to the senses, some being attributed to sight, others to hearing and taste, others to smell and touch. Those of the soul would presumably be allotted to appetite, emotion, reason; though, again, they may be distinguished by the differences of the activities they condition, in so far as activities are engendered by these qualities; or according as they are beneficial or injurious, the benefits and injuries being duly classified. This last is applicable also to the classification of bodily qualities, which also produce differences of benefit and injury: these differences must be regarded as distinctively qualitative; for either the benefit and injury are held to be derived from Quality and the quale, or else some other explanation must be found for them. Enneads: VI I
A point for consideration is how the quale, as conditioned by Quality, can belong to the same category: obviously there can be no single genus embracing both. Enneads: VI I
Further, if “boxer” is in the category of Quality, why not “agent” as well? And with agent goes “active.” Thus “active” need not go into the category of Relation; nor again need “passive,” if “patient” is a quale. Moreover, agent” is perhaps better assigned to the category of Quality for the reason that the term implies power, and power is Quality. But if power as such were determined by Substance [and not by Quality], the agent, though ceasing to be a quale, would not necessarily become a relative. Besides, “active” is not like “greater”: the greater, to be the greater, demands a less, whereas “active” stands complete by the mere possession of its specific character. Enneads: VI I
Wisdom too is generally admitted to exist There. Obviously, if it shares only its name with our wisdom, it is not to be reckoned among things of this sphere; if, however, the import is in both cases the same, then Quality is common to both realms – unless, of course, it be maintained that everything There, including even intellection, is Substance. Enneads: VI I
The “category of Action”: The quantum has been regarded as a single genus on the ground that Quantity and Number are attributes of Substance and posterior to it; the quale has been regarded as another genus because Quality is an attribute of Substance: on the same principle it is maintained that since activity is an attribute of Substance, Action constitutes yet another genus. Enneads: VI I
Does then the action constitute the genus, or the activity from which the action springs, in the same way as Quality is the genus from which the quale is derived? Perhaps activity, action and agent should all be embraced under a single head? But, on the one hand, the action – unlike activity – tends to comport the agent; and on the other, it signifies being in some activity and therefore Being-in-Act [actual as distinct from potential Being]. Consequently the category will be one of Act rather than of Action. Enneads: VI I
Act moreover incontestably manifests itself in Substance, as was found to be the case with Quality: it is connected with Substance as being a form of motion. But Motion is a distinct genus: for, seeing that Quality is a distinct attribute of Substance, and Quality a distinct attribute, and Relative takes its being from the relation of one substance to another, there can be no reason why Motion, also an attribute of Substance, should not also constitute a distinct genus. Enneads: VI I
Does it follow that whenever alteration proceeds from Quality, it will be activity and Action, the quale remaining impassive? It may be that if the quale remains impassive, the alteration will be in the category of Action; whereas if, while its energy is directed outwards, it also suffers – as in beating – it will cease to belong to that category: or perhaps there is nothing to prevent its being in both categories at one and the same moment. Enneads: VI I
If however Possession is not to be predicated of Quality because Quality stands recognised as a category, nor of Quantity because the category of Quantity has been received, nor of parts because they have been assigned to the category of Substance, why should we predicate Possession of weapons, when they too are comprised in the accepted category of Substance? Shoes and weapons are clearly substances. Enneads: VI I
But the error in this theory is fundamental. To set Matter the potential above everything, instead of recognising the primacy of actuality, is in the highest degree perverse. If the potential holds the primacy among the Existents, its actualization becomes impossible; it certainly cannot bring itself into actuality: either the actual exists previously, and so the potential is not the first-principle, or, if the two are to be regarded as existing simultaneously, the first-principles must be attributed to hazard. Besides, if they are simultaneous, why is not actuality given the primacy? Why is the potential more truly real than the actual? Supposing however that the actual does come later than the potential, how must the theory proceed? Obviously Matter does not produce Form: the unqualified does not produce Quality, nor does actuality take its origin in the potential; for that would mean that the actual was inherent in the potential, which at once becomes a dual thing. Enneads: VI I
Again, how can Matter be a first-principle, seeing that it is body? Body must necessarily be a plurality, since all bodies are composite of Matter and Quality. If however body in this case is to be understood in some different way, then Matter is identified with body only by an equivocation. Enneads: VI I
If the possession of three dimensions is given as the characteristic of body, then we are dealing simply with mathematical body. If resistance is added, we are no longer considering a unity: besides, resistance is a quality or at least derived from Quality. Enneads: VI I
But is it not a paradox that, while Matter, the Substrate, is to them an existence, bodies should not have more claim to existence, the universe yet more, and not merely a claim grounded on the reality of one of its parts? It is no less paradoxical that the living form should owe existence not to its soul but to its Matter only, the soul being but an affection of Matter and posterior to it. From what source then did Matter receive ensoulment? Whence, in short, is soul’s entity derived? How does it occur that Matter sometimes turns into bodies, while another part of it turns into Soul? Even supposing that Form might come to it from elsewhere, that accession of Quality to Matter would account not for Soul, but simply for organized body soulless. If, on the contrary, there is something which both moulds Matter and produces Soul, then prior to the produced there must be Soul the producer. Enneads: VI I
And what is this state implanted in Matter? It is either real, or unreal: if real, absolutely bodiless: if unreal, it is introduced to no purpose; Matter is all there is; Quality therefore is nothing. The same is true of State, for that is even more unreal; the alleged Fourth Category more so. Enneads: VI I
Further, how can States constitute a single genus, when there is such manifold diversity among them? How can we group together three yards long” and “white” – Quantity and Quality respectively? Or again Time and Place? How can “yesterday,” “last year,” “in the Lyceum,” “in the Academy,” be States at all? How can Time be in any sense a State? Neither is Time a State nor the events in Time, neither the objects in Space nor Space itself. Enneads: VI I
The above considerations – to which others, doubtless, might be added – suffice to show that these five are primary genera. But that they are the only primary genera, that there are no others, how can we be confident of this? Why do we not add unity to them? Quantity? Quality? Relation, and all else included by our various forerunners? As for unity: If the term is to mean a unity in which nothing else is present, neither Soul nor Intellect nor anything else, this can be predicated of nothing, and therefore cannot be a genus. If it denotes the unity present in Being, in which case we predicate Being of unity, this unity is not primal. Enneads VI,2,
We turn to ask why Quantity is not included among the primary genera, and Quality also. Enneads VI,2,
Why is Quality, again, not included among the Primaries? Because like Quantity it is a posterior, subsequent to Substance. Primary Substance must necessarily contain Quantity and Quality as its consequents; it cannot owe its subsistence to them, or require them for its completion: that would make it posterior to Quality and Quantity. Enneads VI,2,
Now in the case of composite substances – those constituted from diverse elements – number and qualities provide a means of differentiation: the qualities may be detached from the common core around which they are found to group themselves. But in the primary genera there is no distinction to be drawn between simples and composites; the difference is between simples and those entities which complete not a particular substance but Substance as such. A particular substance may very well receive completion from Quality, for though it already has Substance before the accession of Quality, its particular character is external to Substance. But in Substance itself all the elements are substantial. Enneads VI,2,
How then do the four genera complete Substance without qualifying it or even particularizing it? It has been observed that Being is primary, and it is clear that none of the four – Motion, Stability, Difference, Identity – is distinct from it. That this Motion does not produce Quality is doubtless also clear, but a word or two will make it clearer still. Enneads VI,2,
If Motion is the Act of Substance, and Being and the Primaries in general are its Act, then Motion is not an accidental attribute: as the Act of what is necessarily actual [what necessarily involves Act], it is no longer to be considered as the complement of Substance but as Substance itself. For this reason, then, it has not been assigned to a posterior class, or referred to Quality, but has been made contemporary with Being. Enneads VI,2,
As we survey this Magnitude with the beauty of Being within it and the glory and light around it, all contained in Intellect, we see, simultaneously, Quality already in bloom, and along with the continuity of its Act we catch a glimpse of Magnitude at Rest. Then, with one, two and three in Intellect, Magnitude appears as of three dimensions, with Quantity entire. Quantity thus given and Quality, both merging into one and, we may almost say, becoming one, there is at once shape. Difference slips in to divide both Quantity and Quality, and so we have variations in shape and differences of Quality. Identity, coming in with Difference, creates equality, Difference meanwhile introducing into Quantity inequality, whether in number or in magnitude: thus are produced circles and squares, and irregular figures, with number like and unlike, odd and even. Enneads VI,2,
Life, too, burst upon Being, or rather was inseparably bound up with it; and thus it was that all living things of necessity came to be. Body too was there, since Matter and Quality were present. Enneads VI,2,
The “mere predicates” fall under the category of Relation: such are cause and element. The accidents included in the composite substances ire found to be either Quality or Quantity; those which are inclusive are of the nature of Space and Time. Activities and experiences comprise Motions; consequents Space and Time, which are consequents respectively of the Composites and of Motion. Enneads VI,3,
The first three entities [Matter, Form, Composite] go, as we have discovered, to make a single common genus, the Sensible counterpart of Substance. Then follow in order Relation, Quantity, Quality, Time-during-which, Place-in-which, Motion; though, with Time and Space already included [under Relation], Time-during-which and Place-in-which become superfluous. Enneads VI,3,
Thus we have five genera, counting the first three entities as one. If the first three are not massed into a unity, the series will be Matter, Form, Composite, Relation, Quantity, Quality, Motion. The last three may, again, be included in Relation, which is capable of bearing this wider extension. Enneads VI,3,
What, then, we have to ask, is the constant element in the first three entities? What is it that identifies them with their inherent Substance? Is it the capacity to serve as a base? But Matter, we maintain, serves as the base and seat of Form: Form, thus, will be excluded from the category of Substance. Again, the Composite is the base and seat of attributes: hence, Form combined with Matter will be the basic ground of Composites, or at any rate of all posteriors of the Composite – Quantity, Quality, Motion, and the rest. Enneads VI,3,
It may be objected that non-presence in a subject is not peculiar to Substance, inasmuch as the differentia of a substance is no more present in a subject than the substance itself; but this objection results from taking a part of the whole substance, such as “two-footed” in our example, and asserting that this part is not present in a subject: if we take, not “two-footed” which is merely an aspect of Substance, but “two-footedness” by which we signify not Substance but Quality, we shall find that this “two-footedness” is indeed present in a subject. Enneads VI,3,
Do we infer that fire and water are not Substance? They certainly are not Substance because they are visible. Why, then? Because they possess Matter? No. Or Form? No. Nor because they involve a Couplement of Matter and Form. Then why are they Substance? By existing. But does not Quantity exist, and Quality? This anomaly is to be explained by an equivocation in the term “existence.” Enneads VI,3,
The distinction between First and Second Substances, between Fire and a given example of fire, entails a difference of a peculiar kind – the difference between universal and particular. This however is not a difference characteristic of Substance; there is also in Quality the distinction between whiteness and the white object, between grammar and some particular grammar. Enneads VI,3,
How are we to classify the straight line? Shall we deny that it is a magnitude? The suggestion may be made that it is a qualified magnitude. May we not, then, consider straightness as a differentia of “line”? We at any rate draw on Quality for differentiae of Substance. Enneads VI,3,
If however by classing the triangle and the rectangle as qualia we propose to bring figures under Quality, we are not thereby precluded from assigning the same object to more categories than one: in so far as it is a magnitude – a magnitude of such and such a size – it will belong to Quantity; in so far as it presents a particular shape, to Quality. Enneads VI,3,
It may be urged that the triangle is essentially a particular shape. Then what prevents our ranking the sphere also as a quality? To proceed on these lines would lead us to the conclusion that geometry is concerned not with magnitudes but with Quality. But this conclusion is untenable; geometry is the study of magnitudes. The differences of magnitudes do not eliminate the existence of magnitudes as such, any more than the differences of substances annihilate the substances themselves. Enneads VI,3,
Again, when I find Quality bound up with Substance, I regard it as substantial quality: I am not less, but far more, disposed to see in figures or shapes [qualitative] varieties of Quantity. Besides, if we are not to regard them as varieties of magnitude, to what genus are we to assign them? Suppose, then, that we allow differences of magnitude; we commit ourselves to a specific classification of the magnitudes so differentiated. Enneads VI,3,
How far is it true that equality and inequality are characteristic of Quantity? Triangles, it is significant, are said to be similar rather than equal. But we also refer to magnitudes as similar, and the accepted connotation of similarity does not exclude similarity or dissimilarity in Quantity. It may, of course, be the case that the term “similarity” has a different sense here from that understood in reference to Quality. Enneads VI,3,
Furthermore, if we are told that equality and inequality are characteristic of Quantity, that is not to deny that similarity also may be predicated of certain quantities. If, on the contrary, similarity and dissimilarity are to be confined to Quality, the terms as applied to Quantity must, as we have said, bear a different meaning. Enneads VI,3,
But suppose similarity to be identical in both genera; Quantity and Quality must then be expected to reveal other properties held in common. Enneads VI,3,
It remains to enquire whether similarity and dissimilarity are characteristic of Quality. Enneads VI,3,
We have spoken of Quality as combining with other entities, Matter and Quantity, to form the complete Sensible Substance; this Substance, so called, may be supposed to constitute the manifold world of Sense, which is not so much an essence as a quale. Thus, for the essence of fire we must look to the Reason-Principle; what produces the visible aspect is, properly speaking, a quale. Enneads VI,3,
When each of the entities bound up with the pseudo-substance is taken apart from the rest, the name of Quality is given to that one among them, by which without pointing to essence or quantity or motion we signify the distinctive mark, the type or aspect of a thing – for example, the beauty or ugliness of a body. This beauty – need we say? – is identical in name only with Intellectual Beauty: it follows that the term “Quality” as applied to the Sensible and the Intellectual is necessarily equivocal; even blackness and whiteness are different in the two spheres. Enneads VI,3,
But the beauty in the germ, in the particular Reason-Principle – is this the same as the manifested beauty, or do they coincide only in name? Are we to assign this beauty – and the same question applies to deformity in the soul – to the Intellectual order, or to the Sensible? That beauty is different in the two spheres is by now clear. If it be embraced in Sensible Quality, then virtue must also be classed among the qualities of the lower. But merely some virtues will take rank as Sensible, others as Intellectual qualities. Enneads VI,3,
Geometry and arithmetic are, we shall maintain, of a twofold character; in their earthly types they rank with Sensible Quality, but in so far as they are functions of pure Soul, they necessarily belong to that other world in close proximity to the Intellectual. This, too, is in Plato’s view the case with music and astronomy. Enneads VI,3,
The arts concerned with material objects and making use of perceptible instruments and sense-perception must be classed with Sensible Quality, even though they are dispositions of the Soul, attendant upon its apostasy. Enneads VI,3,
Are we, then, to rank the individual soul, as containing these Reason-Principles, with Sensible Substance? But we do not even identify the Principles with body; we merely include them in Sensible Quality on the ground that they are connected with body and are activities of body. The constituents of Sensible Substance have already been specified; we have no intention whatever of adding to them Substance bodiless. Enneads VI,3,
As for Qualities, we hold that they are invariably bodiless, being affections arising within Soul; but, like the Reason-Principles of the individual soul, they are associated with Soul in its apostasy, and are accordingly counted among the things of the lower realm: such affections, torn between two worlds by their objects and their abode, we have assigned to Quality, which is indeed not bodily but manifested in body. Enneads VI,3,
But we refrain from assigning Soul to Sensible Substance, on the ground that we have already referred to Quality [which is Sensible] those affections of Soul which are related to body. On the contrary, Soul, conceived apart from affection and Reason-Principle, we have restored to its origin, leaving in the lower realm no substance which is in any sense Intellectual. Enneads VI,3,
Here a difficulty may be raised: we divide the varieties of Substance and their functions and activities, fair or foul or indeed of any kind whatsoever, on the basis of Quality, Quantity rarely, if ever, entering into the differences which produce species; Quantity, again, we divide in accordance with qualities of its own: how then are we to divide Quality itself into species? what differences are we to employ, and from what genus shall we take them? To take them from Quality itself would be no less absurd than setting up substances as differences of substances. Enneads VI,3,
But consider the sweet as beneficial, the bitter as injurious: then bitter and sweet are distinguished, not by Quality, but by Relation. We might also be disposed to identify the sweet with the thick, and the Pungent with the thin: “thick” however hardly reveals the essence but merely the cause of sweetness – an argument which applies equally to pungency. Enneads VI,3,
We must therefore reflect whether it may be taken as an invariable rule that Quality is never a differentia of Quality, any more than Substance is a differentia of Substance, or Quantity of Quantity. Enneads VI,3,
In the case of virtue and vice, whole must be compared with whole, and the differentiation conducted on this basis. As for the differentia being derived from the same genus as themselves, namely, Quality, and from no other genus, if we proceed on the principle that virtue is bound up with pleasure, vice with lust, virtue again with the acquisition of food, vice with idle extravagance, and accept these definitions as satisfactory, then clearly we have, here too, differentiae which are not qualities. Enneads VI,3,
With Quality we have undertaken to group the dependent qualia, in so far as Quality is bound up with them; we shall not however introduce into this category the qualified objects [qua objects], that we may not be dealing with two categories at once; we shall pass over the objects to that which gives them their [specific] name. Enneads VI,3,
It remains to consider whether blushing should be referred to Quality, even though the person blushing is not included in this category. The fact of becoming flushed is rightly not referred to Quality; for it involves passivity – in short, Motion. But if one has ceased to become flushed and is actually red, this is surely a case of Quality, which is independent of time. How indeed are we to define Quality but by the aspect which a substance presents? By predicating of a man redness, we clearly ascribe to him a quality. Enneads VI,3,
Nonetheless, we must endeavour to find a meaning for the term “contrary.” Can we accept the principle that when things have a certain similarity which is not generic nor in any sense due to admixture, but a similarity residing in their forms – if the term be permitted – they differ in degree but are not contraries; contraries being rather those things which have no specific identity? It would be necessary to stipulate that they belong to the same genus, Quality, in order to cover those immediate contraries which [apparently] have nothing conducing to similarity, inasmuch as there are no intermediates looking both ways, as it were, and having a mutual similarity to each other; some contraries are precluded by their isolation from similarity. Enneads VI,3,
As for Degree [subsisting in Quality], it was given as our opinion that it exists in the objects participating in Quality, though whether it enters into qualities as such – into health and justice – was left open to question. If indeed these qualities possess an extension quite apart from their participants, we must actually ascribe to them degrees: but in truth they belong to a sphere where each entity is the whole and does not admit of degree. Enneads VI,3,
Clearly it cannot be identified with either the Substance or the Quality of the things which possess it. It cannot, further, be consigned to Action, for Passivity also comprises a variety of motions; nor again to Passivity itself, because many motions are actions: on the contrary, actions and passions are to be referred to Motion. Enneads VI,3,
Furthermore, it cannot lay claim to the category of Relation on the mere ground that it has an attributive and not a self-centred existence: on this ground, Quality too would find itself in that same category; for Quality is an attribute and contained in an external: and the same is true of Quantity. Enneads VI,3,
If we are agreed that Quality and Quantity, though attributive, are real entities, and on the basis of this reality distinguishable as Quality and Quantity respectively: then, on the same principle, since Motion, though an attribute has a reality prior to its attribution, it is incumbent upon us to discover the intrinsic nature of this reality. We must never be content to regard as a relative something which exists prior to its attribution, but only that which is engendered by Relation and has no existence apart from the relation to which it owes its name: the double, strictly so called, takes birth and actuality in juxtaposition with a yard’s length, and by this very process of being juxtaposed with a correlative acquires the name and exhibits the fact of being double. Enneads VI,3,
What, then, is that entity, called Motion, which, though attributive, has an independent reality, which makes its attribution possible – the entity corresponding to Quality, Quantity and Substance? But first, perhaps, we should make sure that there is nothing prior to Motion and predicated of it as its genus. Enneads VI,3,
