(19) 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 , that we may not be dealing with two categories at once; we shall pass over the objects to that which gives them their name.

But how are we to classify such terms as "not white"? If "not white" signifies some other colour, it is a quality. But if it is merely a negation of an enumeration of things not white, it will be either a meaningless sound, or else a name or definition of something actual: if a sound, it is a kind of motion; if a name or definition, it is a relative, inasmuch as names and definitions are significant. But if not only the things enumerated are in some one genus, but also the propositions and terms in question must be each of them significative of some genus, then we shall assert that negative propositions and terms posit certain things within a restricted field and deny others. Perhaps, however, it would be better, in view of their composite nature, not to include the negations in the same genus as the affirmations.

What view, then, shall we take of privations? If they are privations of qualities, they will themselves be qualities: "toothless" and "blind," for example, are qualities. "Naked" and "dothed," on the other hand, are neither of them qualities but states: they therefore comport a relation to something else.

Passivity, while it lasts, is not a quality but a motion; when it is a past experience remaining in one's possession, it is a quality; if one ceases to possess the experience then regarded as a finished occurrence, one is considered to have been moved- in other words, to have been in Motion. But in none of these cases is it necessary to conceive of anything but Motion; the idea of time should be excluded; even present time has no right to be introduced.

"Well" and similar adverbial expressions are to be referred to the single generic notion .

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.

We shall accordingly maintain that states alone, and not dispositions, constitute qualities: thus, "hot" is a quality but not "growing hot," "ill" but not "turning ill."

(19) Without going deeply into the matter of the application of this particular Cosmic Principle, we may say that one of the fundamental facts of being discovered by the ancient occultists by the application of the said principle is this: That in every thing there is to be found (1) Substance, or Body; (2) Motion or Active Energy; and (3) Consciousness or Awareness. Therefore, when dealing with planes of being of which, at the time, they had but little knowledge, the ancient occultists always assumed the existence in everything on the unknown plane of these three great forms of manifestation. And all future esoteric investigation and discovery tended to disclose facts corroborating and sustaining the original assumption derived by analogy, and the discoveries of modern science have invariably tended in the same direction.

(28) We have already indicated that Activity and Passivity are to be regarded as motions, and that it is possible to distinguish absolute motions, actions, passions.

As for the remaining so-called genera, we have shown that they are reducible to those which we have posited.

With regard to the relative, we have maintained that Relation belongs to one object as compared with another, that the two objects coexist simultaneously, and that Relation is found wherever a substance is in such a condition as to produce it; not that the substance is a relative, except in so far as it constitutes part of a whole- a hand, for example, or head or cause or principle or element.

We may also adopt the ancient division of relatives into creative principles, measures, excesses and deficiencies, and those which in general separate objects on the basis of similarities and differences.

Our investigation into the kinds of Being is now complete.

(1) A distinction is made between things existing actually and things existing potentially; a certain Actuality, also, is spoken of as a really existent entity. We must consider what content there is in these terms.

Can we distinguish between Actuality and the state of being-in-act? And if there is such an Actuality, is this itself in Act, or are the two quite distinct so that this actually existent thing need not be, itself, an Act?

It is indubitable that Potentiality exists in the Realm of Sense: but does the Intellectual Realm similarly include the potential or only the actual? and if the potential exists there, does it remain merely potential for ever? And, if so, is this resistance to actualization due to its being precluded from time-processes?

First we must make clear what potentiality is.

We cannot think of potentiality as standing by itself; there can be no potentiality apart from something which a given thing may be or become. Thus bronze is the potentiality of a statue: but if nothing could be made out of the bronze, nothing wrought upon it, if it could never be anything as a future to what it has been, if it rejected all change, it would be bronze and nothing else: its own character it holds already as a present thing, and that would be the full of its capacity: it would be destitute of potentiality. Whatsoever has a potentiality must first have a character of its own; and its potentiality will consist in its having a reach beyond that character to some other.

Sometimes after it has turned its potentiality into actuality it will remain what it was; sometimes it will sink itself to the fullest extent in the new form and itself disappear: these two different modes are exemplified in (1) bronze as potentially a statue and (2) water as potentially bronze or, again, air as potentially fire.

But if this be the significance of potentiality, may we describe it as a Power towards the thing that is to be? Is the Bronze a power towards a statue?

Not in the sense of an effectively productive force: such a power could not be called a potentiality. Of course Potentiality may be a power, as, for instance, when we are referring not merely to a thing which may be brought into actualization but to Actuality itself : but it is better, as more conducive to clarity, to use "Potentiality" in regard to the process of Actualization and "Power" in regard to the Principle, Actuality.

Potentiality may be thought of as a Substratum to states and shapes- and forms which are to be received, which it welcomes by its nature and even strives for- sometimes in gain but sometimes, also, to loss, to the annulling of some distinctive manner of Being already actually achieved.

(11) For of objects that are moved, some are moved by impulse and appearance, as animals; and some by transposition, as inanimate objects. And of things without life, plants, they say, are moved by transposition in order to growth, if we will concede to them that plants are without life. To stones, then, belongs a permanent state. Plants have a nature; and the irrational animals possess impulse and perception, and likewise the two characteristics already specified.

(3) We come now to the purpose of all this discussion; to make clear in what sense or to what degree Actualization is predicable in the Intellectual Realm and whether all is in Actualization there, each and every member of that realm being an Act, or whether Potentiality also has place there.

Now: if there is no Matter there to harbour potentiality: if nothing there has any future apart from its actual mode: if nothing there generates, whether by changes or in the permanence of its identity; if nothing goes outside of itself to give being to what is other than itself; then, potentiality has no place there: the Beings there possess actuality as belonging to eternity, not to time.

Those, however, who assert Matter in the Intellectual Realm will be asked whether the existence of that Matter does not imply the potential there too; for even if Matter there exists in another mode than here, every Being there will have its Matter, its form and the union of the two . What answer is to be made?

Simply, that even the Matter there is Idea, just as the Soul, an Idea, is Matter to another Being.

But relatively to that higher, the Soul is a potentiality?

No: for the Idea is integral to the Soul and does not look to a future; the distinction between the Soul and its Idea is purely mental: the Idea and the Matter it includes are conceived as a conjunction but are essentially one Kind: remember that Aristotle makes his Fifth Body immaterial.

But surely Potentiality exists in the Soul? Surely the Soul is potentially the living-being of this world before it has become so? Is it not potentially musical, and everything else that it has not been and becomes? Does not this imply potentiality even in the Intellectual Existences?

No: the Soul is not potentially these things; it is a Power towards them.

But after what mode does Actualization exist in the Intellectual Realm?

Is it the Actualization of a statue, where the combination is realized because the Form-Idea has mastered each separate constituent of the total?

No: it is that every constituent there is a Form-Idea and, thus, is perfect in its Being.

There is in the Intellectual Principle no progression from some power capable of intellection to the Actuality of intellection: such a progression would send us in search of a Prior Principle not progressing from Power to Act; there all stands ever realized. Potentiality requires an intervention from outside itself to bring it to the actualization which otherwise cannot be; but what possesses, of itself, identity unchangeable for ever is an actualization: all the Firsts then are actualizations, simply because eternally and of themselves they possess all that is necessary to their completion.

This applies equally to the Soul, not to that in Matter but to that in the Intellectual Sphere; and even that in Matter, the Soul of Growth, is an actualization in its difference; it possesses actually the Being that belongs to it.

Then, everything, in the intellectual is in actualization and so all There is Actuality?

Why not? If that Nature is rightly said to be "Sleepless," and to be Life and the noblest mode of Life, the noblest Activities must be there; all then is actualization there, everything is an Actuality, for everything is a Life, and all Place there is the Place of Life, in the true sense the ground and spring of Soul and of the Intellectual Principle.

(15) 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.

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 , 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.

The truth is not that Being first is and then takes Motion, first is and then acquires Stability: neither Stability nor Motion is a mere modification of Being. Similarly, Identity and Difference are not later additions: Being did not grow into plurality; its very unity was a plurality; but plurality implies Difference, and unity-in-plurality involves Identity.

Substance requires no more than these five constituents; but when we have to turn to the lower sphere, we find other principles giving rise no longer to Substance (as such) but to quantitative Substance and qualitative: these other principles may be regarded as genera but not primary genera.

(7) What, then, are the several entities observable in this plurality?

We have found Substance and life simultaneously present in Soul. Now, this Substance is a common property of Soul, but life, common to all souls, differs in that it is a property of Intellect also.

Having thus introduced Intellect and its life we make a single genus of what is common to all life, namely, Motion. Substance and the Motion, which constitutes the highest life, we must consider as two genera; for even though they form a unity, they are separable to thought which finds their unity not a unity; otherwise, it could not distinguish them.

Observe also how in other things Motion or life is clearly separated from Being- a separation impossible, doubtless, in True Being, but possible in its shadow and namesake. In the portrait of a man much is left out, and above all the essential thing, life: the "Being" of sensible things just such a shadow of True Being, an abstraction from that Being complete which was life in the Archetype; it is because of this incompleteness that we are able in the Sensible world to separate Being from life and life from Being.

Being, then, containing many species, has but one genus. Motion, however, is to be classed as neither a subordinate nor a supplement of Being but as its concomitant; for we have not found Being serving as substrate to Motion. Motion is being Act; neither is separated from the other except in thought; the two natures are one; for Being is inevitably actual, not potential.

No doubt we observe Motion and Being separately, Motion as contained in Being and Being as involved in Motion, and in the individual they may be mutually exclusive; but the dualism is an affirmation of our thought only, and that thought sees either form as a duality within a unity.

Now Motion, thus manifested in conjunction with Being, does not alter Being's nature- unless to complete its essential character- and it does retain for ever its own peculiar nature: at once, then, we are forced to introduce Stability. To reject Stability would be more unreasonable than to reject Motion; for Stability is associated in our thought and conception with Being even more than with Motion; unalterable condition, unchanging mode, single Reason-Principle- these are characteristics of the higher sphere.

Stability, then, may also be taken as a single genus. Obviously distinct from Motion and perhaps even its contrary, that it is also distinct from Being may be shown by many considerations. We may especially observe that if Stability were identical with Being, so also would Motion be, with equal right. Why identity in the case of Stability and not in that of Motion, when Motion is virtually the very life and Act both of Substance and of Absolute Being? However, on the very same principle on which we separated Motion from Being with the understanding that it is the same and not the same- that they are two and yet one- we also separate Stability from Being, holding it, yet, inseparable; it is only a logical separation entailing the inclusion among the Existents of this other genus. To identify Stability with Being, with no difference between them, and to identify Being with Motion, would be to identify Stability with Motion through the mediation of Being, and so to make Motion and Stability one and the same thing.

(10) 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.

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!

Perhaps, however, qualities are conditioned by powers which are posterior to the substances as such . 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.

The differences distinguishing substances from each other are called qualities only by analogy; they are, more strictly, Acts and Reason-Principles, or parts of Reason-Principles, and though they may appear merely to qualify the substance, they in fact indicate its essence.

Qualities in the true sense- those, that is, which determine qualia- being in accordance with our definition powers, will in virtue of this common ground be a kind of Reason-Principle; they will also be in a sense Forms, that is, excellences and imperfections whether of soul or of body.

But how can they all be powers? Beauty or health of soul or body, very well: but surely not ugliness, disease, weakness, incapacity. In a word, is powerlessness a power?

It may be urged that these are qualities in so far as qualia are also named after them: but may not the qualia be so called by analogy, and not in the strict sense of the single principle? Not only may the term be understood in the four ways , but each of the four may have at least a twofold significance.

In the first place, Quality is not merely a question of action and passion, involving a simple distinction between the potentially active 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.

Again, not all qualities can be regarded as Reason-Principles: chronic disease cannot be a Reason-Principle. Perhaps, however, we must speak in such cases of privations, restricting the term "Quantities" to Ideal-Forms and powers. Thus we shall have, not a single genus, but reference only to the unity of a category. Knowledge will be regarded as a Form and a power, ignorance as a privation and powerlessness.

On the other hand, powerlessness and disease are a kind of Form; disease and vice have many powers though looking to evil.

But how can a mere failure be a power? Doubtless the truth is that every quality performs its own function independently of a standard; for in no case could it produce an effect outside of its power.

Even beauty would seem to have a power of its own. Does this apply to triangularity?

Perhaps, after all, it is not a power we must consider, but a disposition. Thus, qualities will be determined by the forms and characteristics of the object qualified: their common element, then, will be Form and ideal type, imposed upon Substance and posterior to it.

But then, how do we account for the powers? We may doubtless remark that even the natural boxer is so by being constituted in a particular way; similarly, with the man unable to box: to generalize, the quality is a characteristic non-essential. Whatever is seen to apply alike to Being and to non-Being, as do heat and whiteness and colours generally, is either different from Being- is, for example, an Act of Being- or else is some secondary of Being, derived from it, contained in it, its image and likeness.

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.

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.

But triangularity is a quality of that in which it is present; it is however no longer triangularity as such, but the triangularity present in that definite object and modified in proportion to its success in shaping that object.

(20) But though not opposed, it is still different from Action and cannot belong to the same genus as activity; though if they are both Motion, it will so belong, on the principle that alteration must be regarded as qualitative motion.

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.

If then an alteration be conditioned by Passivity alone, as is the case with rubbing, on what ground is it assigned to Action rather than to Passivity? Perhaps the Passivity arises from the fact that a counter-rubbing is involved. But are we, in view of this counter-motion, to recognize the presence of two distinct motions? No: one only.

How then can this one motion be both Action and Passion? We must suppose it to be Action in proceeding from an object, and Passion in being directly upon another- though it remains the same motion throughout.

Suppose however Passion to be a different motion from Action: how then does its modification of the patient object change that patient's character without the agent being affected by the patient? For obviously an agent cannot be passive to the operation it performs upon another. Can it be that the fact of motion existing elsewhere creates the Passion, which was not Passion in the agent?

If the whiteness of the swan, produced by its Reason-Principle, is given at its birth, are we to affirm Passion of the swan on its passing into being? If, on the contrary, the swan grows white after birth, and if there is a cause of that growth and the corresponding result, are we to say that the growth is a Passion? Or must we confine Passion to purely qualitative change?

One thing confers beauty and another takes it: is that which takes beauty to be regarded as patient? If then the source of beauty- tin, suppose- should deteriorate or actually disappear, while the recipient- copper- improves, are we to think of the copper as passive and the tin active?

Take the learner: how can he be regarded as passive, seeing that the Act of the agent passes into him ? How can the Act, necessarily a simple entity, be both Act and Passion? No doubt the Act is not in itself a Passion; nonetheless, the learner coming to possess it will be a patient by the fact of his appropriation of an experience from outside: he will not, of course, be a patient in the sense of having himself performed no Act; learning- like seeing- is not analogous to being struck, since it involves the acts of apprehension and recognition.

(1) For every question is solved from pre-existing knowledge. And the knowledge pre-existing of each object of investigation is sometimes merely of the essence, while its functions are unknown (as of stones, and plants, and animals, of whose operations we are ignorant), or [the knowledge] of the properties, or powers, or (so to speak) of the qualities inherent in the objects. And sometimes we may know some one or more of those powers or properties, - as, for example, the desires and affections of the soul, - and be ignorant of the essence, and make it the object of investigation. But in many instances, our understanding having assumed all these, the question is, in which of the essences do they thus inhere; for it is after forming conceptions of both - that is, both of essence and operation - in our mind, that we proceed to the question. And there are also some objects, whose operations, along with their essences, we know, but are ignorant of their modifications.

(5) These are incontrovertible facts in regard to the pseudo-substance of the Sensible realm: if they apply also in some degree to the True Substance of the Intellectual, the coincidence is, doubtless, to be attributed to analogy and ambiguity of terms.

We are aware that "the first" is so called only in relation to the things which come after it: "first" has no absolute significance; the first of one series is subsequent to the last of another. "Substrate," similarly, varies in meaning , while as for passivity its very existence in the Intellectual is questionable; if it does exist there, it is not the passivity of the Sensible.

It follows that the fact of "not being present in a subject is not universally true of Substance, unless presence in a subject be stipulated as not including the case of the part present in the whole or of one thing combining with another to form a distinct unity; a thing will not be present as in a subject in that with which it co-operates in the information of a composite substance. Form, therefore, is not present in Matter as in a subject, nor is Man so present in Socrates, since Man is part of Socrates.

Substance, then, is that which is not present in a subject. But if we adopt the definition "neither present in a subject nor predicated of a subject," we must add to the second "subject" the qualification "distinct," in order that we may not exclude the case of Man predicated of a particular man. When I predicate Man of Socrates, it is as though I affirmed, not that a piece of wood is white, but that whiteness is white; for in asserting that Socrates is a man, I predicate Man of a particular man, I affirm Man of the manhood in Socrates; I am really saying only that Socrates is Socrates, or that this particular rational animal is an animal.

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.

We may be told that neither Time nor Place is present in a subject. But if the definition of Time as the measure of Motion be regarded as denoting something measured, the "measure" will be present in Motion as in a subject, while Motion will be present in the moved: if, on the contrary, it be supposed to signify a principle of measurement, the "measure" will be present in the measurer.

Place is the limit of the surrounding space, and thus is present in that space.

The truth is, however, that the "Substance" of our enquiry may be apprehended in directly opposite ways: it may be determined by one of the properties we have been discussing, by more than one, by all at once, according as they answer to the notions of Matter, Form and the Couplement.

(8) It is a general principle that, to be modified, an object must be opposed in faculty, and in quality to the forces that enter and act upon it.

Thus where heat is present, the change comes by something that chills, where damp by some drying agency: we say a subject is modified when from warm it becomes cold, from dry wet.

A further evidence is in our speaking of a fire being burned out, when it has passed over into another element; we do not say that the Matter has been burned out: in other words, modification affects what is subject to dissolution; the acceptance of modification is the path towards dissolution; susceptibility to modification and susceptibility to dissolution go necessarily together. But Matter can never be dissolved. What into? By what process?

Still: Matter harbours heat, cold, qualities beyond all count; by these it is differentiated; it holds them as if they were of its very substance and they blend within it- since no quality is found isolated to itself- Matter lies there as the meeting ground of all these qualities with their changes as they act and react in the blend: how, then, can it fail to be modified in keeping? The only escape would be to declare Matter utterly and for ever apart from the qualities it exhibits; but the very notion of Substance implies that any and every thing present in it has some action upon it.

(18) There are other questions calling for consideration:

First: Are both Acts and motions to be included in the category of Action, with the distinction that Acts are momentary while Motions, such as cutting, are in time? Or will both be regarded as motions or as involving Motion?

Secondly: Will all activities be related to passivity, or will some- for example, walking and speaking- be considered as independent of it?

Thirdly: Will all those related to passivity be classed as motions and the independent as Acts, or will the two classes overlap? Walking, for instance, which is an independent, would, one supposes, be a motion; thinking, which also does not essentially involve "passivity," an Act: otherwise we must hold that thinking and walking are not even actions. But if they are not in the category of Action, where then in our classification must they fall?

It may perhaps be urged that the act of thinking, together with the faculty of thought, should be regarded as relative to the thought object; for is not the faculty of sensation treated as relative to the sensible object? If then, we may ask, in the analogue the faculty of sensation is treated as relative to the sensible object, why not the sensory act as well? The fact is that even sensation, though related to an external object, has something besides that relation: it has, namely, its own status of being either an Act or a Passion. Now the Passion is separable from the condition of being attached to some object and caused by some object: so, then, is the Act a distinct entity. Walking is similarly attached and caused, and yet has besides the status of being a motion. It follows that thought, in addition to its relationship, will have the status of being either a motion or an Act.

(2) Our first observations must be directed to what passes in the Sensible realm for Substance. It is, we shall agree, only by analogy that the nature manifested in bodies is designated as Substance, and by no means because such terms as Substance or Being tally with the notion of bodies in flux; the proper term would be Becoming.

But Becoming is not a uniform nature; bodies comprise under the single head simples and composites, together with accidentals or consequents, these last themselves capable of separate classification.

Alternatively, Becoming may be divided into Matter and the Form imposed upon Matter. These may be regarded each as a separate genus, or else both may be brought under a single category and receive alike the name of Substance.

But what, we may ask, have Matter and Form in common? In what sense can Matter be conceived as a genus, and what will be its species? What is the differentia of Matter? In which genus, Matter or Form, are we to rank the composite of both? It may be this very composite which constitutes the Substance manifested in bodies, neither of the components by itself answering to the conception of Body: how, then, can we rank them in one and the same genus as the composite? How can the elements of a thing be brought within the same genus as the thing itself? Yet if we begin with bodies, our first-principles will be compounds.

Why not resort to analogy? Admitted that the classification of the Sensible cannot proceed along the identical lines marked out for the Intellectual: is there any reason why we should not for Intellectual-Being substitute Matter, and for Intellectual Motion substitute Sensible Form, which is in a sense the life and consummation of Matter? The inertia of Matter would correspond with Stability, while the Identity and Difference of the Intellectual would find their counterparts in the similarity and diversity which obtain in the Sensible realm.

But, in the first place, Matter does not possess or acquire Form as its life or its Act; Form enters it from without, and remains foreign to its nature. Secondly, Form in the Intellectual is an Act and a motion; in the Sensible Motion is different from Form and accidental to it: Form in relation to Matter approximates rather to Stability than to Motion; for by determining Matter's indetermination it confers upon it a sort of repose.

In the higher realm Identity and Difference presuppose a unity at once identical and different: a thing in the lower is different only by participation in Difference and in relation to some other thing; Identity and Difference are here predicated of the particular, which is not, as in that realm, a posterior.

As for Stability, how can it belong to Matter, which is distorted into every variety of mass, receiving its forms from without, and even with the aid of these forms incapable of offspring.

This mode of division must accordingly be abandoned.

(3) The Whiteness, therefore, in a human being is, clearly, to be classed not as a quality but as an activity- the act of a power which can make white; and similarly what we think of as qualities in the Intellectual Realm should be known as activities; they are activities which to our minds take the appearance of quality from the fact that, differing in character among themselves, each of them is a particularity which, so to speak, distinguishes those Realities from each other.

What, then, distinguishes Quality in the Intellectual Realm from that here, if both are Acts?

The difference is that these in the Supreme do not indicate the very nature of the Reality nor do they indicate variations of substance or of character; they merely indicate what we think of as Quality but in the Intellectual Realm must still be Activity.

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 - 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.

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.

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.

But the Archetypes of all such qualities, the foundation in which they exist primarily, these are Activities of the Intellectual Beings.

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.

Finally, anything which is never Form but always accidental to something else is Quality unmixed and nothing more.

(9) In answer: It must, first, be noted that there are a variety of modes in which an object may be said to be present to another or to exist in another. There is a "presence" which acts by changing the object- for good or for ill- as we see in the case of bodies, especially where there is life. But there is also a "presence" which acts, towards good or ill, with no modification of the object, as we have indicated in the case of the Soul. Then there is the case represented by the stamping of a design upon wax, where the "presence" of the added pattern causes no modification in the substance nor does its obliteration diminish it. And there is the example of Light whose presence does not even bring change of pattern to the object illuminated. A stone becoming cold does not change its nature in the process; it remains the stone it was. A drawing does not cease to be a drawing for being coloured.

The intermediary mass on which these surface changes appear is certainly not transmuted by them; but might there not be a modification of the underlying Matter?

No: it is impossible to think of Matter being modified by, for instance, colour- for, of course we must not talk of modification when there is no more than a presence, or at most a presenting of shape.

Mirrors and transparent objects, even more, offer a close parallel; they are quite unaffected by what is seen in or through them: material things are reflections, and the Matter on which they appear is further from being affected than is a mirror. Heat and cold are present in Matter, but the Matter itself suffers no change of temperature: growing hot and growing cold have to do only with quality; a quality enters and brings the impassible Substance under a new state- though, by the way, research into nature may show that cold is nothing positive but an absence, a mere negation. The qualities come together into Matter, but in most cases they can have no action upon each other; certainly there can be none between those of unlike scope: what effect, for example, could fragrance have on sweetness or the colour-quality on the quality of form, any quality on another of some unrelated order? The illustration of the mirror may well indicate to us that a given substratum may contain something quite distinct from itself- even something standing to it as a direct contrary- and yet remain entirely unaffected by what is thus present to it or merged into it.

A thing can be hurt only by something related to it, and similarly things are not changed or modified by any chance presence: modification comes by contrary acting upon contrary; things merely different leave each other as they were. Such modification by a direct contrary can obviously not occur in an order of things to which there is no contrary: Matter, therefore cannot be modified: any modification that takes place can occur only in some compound of Matter and reality, or, speaking generally, in some agglomeration of actual things. The Matter itself- isolated, quite apart from all else, utterly simplex- must remain immune, untouched in the midst of all the interacting agencies; just as when people fight within their four walls, the house and the air in it remain without part in the turmoil.

We may take it, then, that while all the qualities and entities that appear upon Matter group to produce each the effect belonging to its nature, yet Matter itself remains immune, even more definitely immune than any of those qualities entering into it which, not being contraries, are not affected by each other.

(15) 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.

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 . Consequently the category will be one of Act rather than of Action.

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.

(2) Then the question rises whether Matter- potentially what it becomes by receiving shape- is actually something else or whether it has no actuality at all. In general terms: When a potentiality has taken a definite form, does it retain its being? Is the potentiality, itself, in actualization? The alternative is that, when we speak of the "Actual Statue" and of the "Potential Statue," the Actuality is not predicated of the same subject as the "Potentiality." If we have really two different subjects, then the potential does not really become the actual: all that happens is that an actual entity takes the place of a potential.

The actualized entity is not the Matter but a combination, including the Form-Idea upon the Matter.

This is certainly the case when a quite different thing results from the actualization-statue, for example, the combination, is distinctly different from the bronze, the base; where the resultant is something quite new, the Potentiality has clearly not, itself, become what is now actualized. But take the case where a person with a capacity for education becomes in fact educated: is not potentiality, here, identical with actualization? Is not the potentially wise Socrates the same man as the Socrates actually wise?

But is an ignorant man a being of knowledge because he is so potentially? Is he, in virtue of his non-essential ignorance, potentially an instructed being?

It is not because of his accidental ignorance that he is a being of Knowledge: it is because, ignorant though he be by accident, his mind, apt to knowledge, is the potentiality through which he may become so. Thus, in the case of the potentially instructed who have become so in fact, the potentiality is taken up into the actual; or, if we prefer to put it so, there is on the one side the potentiality while, on the other, there is the power in actual possession of the form.

If, then, the Potentiality is the Substratum while the thing in actualization- the Statue for example a combination, how are we to describe the form that has entered the bronze?

There will be nothing unsound in describing this shape, this Form which has brought the entity from potentiality to actuality, as the actualization; but of course as the actualization of the definite particular entity, not as Actuality the abstract: we must not confuse it with the other actualization, strictly so called, that which is contrasted with the power producing actualization. The potential is led out into realization by something other than itself; power accomplishes, of itself, what is within its scope, but by virtue of Actuality : the relation is that existing between a temperament and its expression in act, between courage and courageous conduct. So far so good:

(12) If then we do not propose to divide Quality in this 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.

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.

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 , 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.

It may however be urged that while the possession of that character makes it a quale, it is a relative in so far as it directs upon an external object the power indicated by its name. Why, then, is not "boxer" a relative, and "boxing" as well? Boxing is entirely related to an external object; its whole theory pre-supposes this external. And in the case of the other arts- or most of them- investigation would probably warrant the assertion that in so far as they affect the soul they are qualities, while in so far as they look outward they are active and as being directed to an external object are relatives. They are relatives in the other sense also that they are thought of as habits.

Can it then be held that there is any distinct reality implied in activity, seeing that the active is something distinct only according as it is a quale? It may perhaps be held that the tendency towards action of living beings, and especially of those having freewill, implies a reality of activity .

But what is the function of the active in connection with those non-living powers which we have classed as qualities? Doubtless to recruit any object it encounters, making the object a participant in its content.

But if one same object both acts and is acted upon, how do we then explain the active? Observe also that the greater- in itself perhaps a fixed three yards' length- will present itself as both greater and less according to its external contacts.

It will be objected that greater and less are due to participation in greatness and smallness; and it might be inferred that a thing is active or passive by participation in activity or passivity.

This is the place for enquiring also whether the qualities of the Sensible and Intellectual realms can be included under one head- a question intended only for those who ascribe qualities to the higher realm as well as the lower. And even if Ideal Forms of qualities are not posited, yet once the term "habit" is used in reference to Intellect, the question arises whether there is anything common to that habit and the habit we know in the lower.

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.

This question, however, applies to all the categories: are the two spheres irreconcilable, or can they be co-ordinated with a unity?
