(1) In the two orders of things- those whose existence is that of process and those in whom it is Authentic Being- there is a variety of possible relation to Cause.

Cause might conceivably underly all the entities in both orders or none in either. It might underly some, only, in each order, the others being causeless. It might, again, underly the Realm of Process universally while in the Realm of Authentic Existence some things were caused, others not, or all were causeless. Conceivably, on the other hand, the Authentic Existents are all caused while in the Realm of Process some things are caused and others not, or all are causeless.

Now, to begin with the Eternal Existents:

The Firsts among these, by the fact that they are Firsts, cannot be referred to outside Causes; but all such as depend upon those Firsts may be admitted to derive their Being from them.

And in all cases the Act may be referred to the Essence , for their Essence consists, precisely, in giving forth an appropriate Act.

As for Things of Process- or for Eternal Existents whose Act is not eternally invariable- we must hold that these are due to Cause; Causelessness is quite inadmissible; we can make no place here for unwarranted "slantings," for sudden movement of bodies apart from any initiating power, for precipitate spurts in a soul with nothing to drive it into the new course of action. Such causelessness would bind the Soul under an even sterner compulsion, no longer master of itself, but at the mercy of movements apart from will and cause. Something willed- within itself or without- something desired, must lead it to action; without motive it can have no motion.

On the assumption that all happens by Cause, it is easy to discover the nearest determinants of any particular act or state and to trace it plainly to them.

The cause of a visit to the centre of affairs will be that one thinks it necessary to see some person or to receive a debt, or, in a word, that one has some definite motive or impulse confirmed by a judgement of expediency. Sometimes a condition may be referred to the arts, the recovery of health for instance to medical science and the doctor. Wealth has for its cause the discovery of a treasure or the receipt of a gift, or the earning of money by manual or intellectual labour. The child is traced to the father as its Cause and perhaps to a chain of favourable outside circumstances such as a particular diet or, more immediately, a special organic aptitude or a wife apt to childbirth.

And the general cause of all is Nature.

(46) Timaeus: the causes which belong to the Intelligent Nature, and put second all such as are of the class of things which are moved by others, and themselves, in turn, move others because they cannot help it. And we also must act likewise. We must declare both kinds of Causes, but keep distinct those which, with the aid of thought, are artificers of things fair and good, and all those which are devoid of intelligence and produce always accidental and irregular effects. Now regarding the auxiliary causes which have helped the eyes to acquire the power which they now possess, let this statement suffice. Next we must declare the most important

(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:

(28) Timaeus: and has no Becoming? And what is that which is Becoming always and never is Existent? Now the one of these is apprehensible by thought with the aid of reasoning, since it is ever uniformly existent; whereas the other is an object of opinion with the aid of unreasoning sensation, since it becomes and perishes and is never really existent. Again, everything which becomes must of necessity become owing to some Cause; for without a cause it is impossible for anything to attain becoming. But when the artificer of any object, in forming its shape and quality, keeps his gaze fixed on that which is uniform, using a model of this kind, that object, executed in this way, must of necessity

(68) Timaeus: Such, then, being the necessary nature of all these things, the Artificer of the most fair and good took them over at that time amongst things generated when He was engendering the self-sufficing and most perfect God; and their inherent properties he used as subservient causes, but Himself designed the Good in all that was being generated. Wherefore one ought to distinguish two kinds of causes, the necessary and the divine, and in all things to seek after the divine for the sake of gaining a life of blessedness, so far as our nature admits thereof,

(46) Timaeus: the Form of the Most Good; but by the most of men they are supposed to be not auxiliary but primary causes of all things—cooling and heating, solidifying and dissolving, and producing all such effects. Yet they are incapable of possessing reason and thought for any purpose. For, as we must affirm, the one and only existing thing which has the property of acquiring thought is Soul; and Soul is invisible, whereas fire and water and earth and air are all visible bodies; and the lover of thought and knowledge must needs pursue first

(6) We are led thus to the question of receptivity in things of body.

An additional proof that bodies must have some substratum different from themselves is found in the changing of the basic-constituents into one another. Notice that the destruction of the elements passing over is not complete- if it were we would have a Principle of Being wrecked in Non-being- nor does an engendered thing pass from utter non-being into Being: what happens is that a new form takes the place of an old. There is, then, a stable element, that which puts off one form to receive the form of the incoming entity.

The same fact is clearly established by decay, a process implying a compound object; where there is decay there is a distinction between Matter and Form.

And the reasoning which shows the destructible to be a compound is borne out by practical examples of reduction: a drinking vessel is reduced to its gold, the gold to liquid; analogy forces us to believe that the liquid too is reducible.

The basic-constituents of things must be either their Form-Idea or that Primal Matter or a compound of the Form and Matter.

Form-Idea, pure and simple, they cannot be: for without Matter how could things stand in their mass and magnitude?

Neither can they be that Primal Matter, for they are not indestructible.

They must, therefore, consist of Matter and Form-Idea- Form for quality and shape, Matter for the base, indeterminate as being other than Idea.

(7) But Matter, it may be contended, is the source of existence to the Sensible things implanted in it. From what source, then, we retort, does Matter itself derive existence and being?

That Matter is not a Primary we have established elsewhere. If it be urged that other things can have no subsistence without being implanted in Matter, we admit the claim for Sensible things. But though Matter be prior to these, it is not thereby precluded from being posterior to many things-posterior, in fact, to all the beings of the Intellectual sphere. Its existence is but a pale reflection, and less complete than that of the things implanted in it. These are Reason-Principles and more directly derived from Being: Matter has of itself no Reason-Principle whatever; it is but a shadow of a Principle, a vain attempt to achieve a Principle.

But, our critic may pursue, Matter gives existence to the things implanted in it, just as Socrates gives existence to the whiteness implanted in himself? We reply that the higher being gives existence to the lower, the lower to the higher never.

But once concede that Form is higher in the scale of Being than Matter, and Matter can no longer be regarded as a common ground of both, nor Substance as a genus embracing Matter, Form and the Couplement. True, these will have many common properties, to which we have already referred, but their being will nonetheless be different. When a higher being comes into contact with a lower, the lower, though first in the natural order, is yet posterior in the scale of Reality: consequently, if Being does not belong in equal degrees to Matter, to Form and to the Couplement, Substance can no longer be common to all three in the sense of being their genus: to their posteriors it will bear a still different relation, serving them as a common base by being bound up with all alike. Substance, thus, resembles life, dim here, clearer there, or portraits of which one is an outline, another more minutely worked. By measuring Being by its dim manifestation and neglecting a fuller revelation elsewhere, we may come to regard this dim existence as a common ground.

But this procedure is scarcely permissible. Every being is a distinct whole. The dim manifestation is in no sense a common ground, just as there is no common ground in the vegetal, the sensory and the intellectual forms of life.

We conclude that the term "Being" must have different connotations as applied to Matter, to Form and to both conjointly, in spite of the single source pouring into the different streams.

Take a second derived from a first and a third from the second: it is not merely that the one will rank higher and its successor be poorer and of lower worth; there is also the consideration that, even deriving from the same source, one thing, subjected in a certain degree to fire, will give us an earthen jar, while another, taking less of the heat, does not produce the jar.

Perhaps we cannot even maintain that Matter and Form are derived from a single source; they are clearly in some sense different.

(16) But even there we are not to remain always, in that beauty of the multiple; we must make haste yet higher, above this heaven of ours and even that; leaving all else aside we ask in awe "Who produced that realm and how?" Everything There is a single Idea in an individual impression and, informed by The Good, possesses the universal good transcendent over all. Each possessing that Being above, possesses also the total Living-Form in virtue of that transcendent life, possesses, no doubt, much else as well.

But what is the Nature of this Transcendent in view of which and by way of which the Ideas are good?

The best way of putting the question is to ask whether, when Intellectual-Principle looked towards The Good, it had Intellection of that unity as a multiplicity and, itself a unity, plied its Act by breaking into parts what it was too feeble to know as a whole.

No: that would not be Intellection looking upon the Good; it would be a looking void of Intellection. We must think of it not as looking but as living; dependent upon That, it kept itself turned Thither; all the tendance taking place There and upon That must be a movement teeming with life and must so fill the looking Principle; there is no longer bare Act, there is a filling to saturation. Forthwith Intellectual-Principle becomes all things, knows that fact in virtue of its self-knowing and at once becomes Intellectual-Principle, filled so as to hold within itself that object of its vision, seeing all by the light from the Giver and bearing that Giver with it.

In this way the Supreme may be understood to be the cause at once of essential reality and of the knowing of reality. The sun, cause of the existence of sense-things and of their being seen, is indirectly the cause of sight, without being either the faculty or the object: similarly this Principle, The Good, cause of Being and Intellectual-Principle, is a light appropriate to what is to be seen There and to their seer; neither the Beings nor the Intellectual-Principle, it is their source and by the light it sheds upon both makes them objects of Intellection. This filling procures the existence; after the filling, the being; the existence achieved, the seeing followed: the beginning is that state of not yet having been filled, though there is, also, the beginning which means that the Filling Principle was outside and by that act of filling gave shape to the filled.

(2) Thus we have even here the means of knowing the nature of the Intellectual-Principle, though, seeing it more closely than anything else, we still see it at less than its worth. We know that it exists but its cause we do not see, or, if we do, we see that cause as something apart. We see a man- or an eye, if you like- but this is an image or part of an image; what is in that Principle is at once Man and the reason of his being; for There man- or eye- must be, itself, an intellective thing and a cause of its being; it could not exist at all unless it were that cause, whereas here, everything partial is separate and so is the cause of each. In the Intellectual, all is at one so that the thing is identical with the cause.

Even here the thing and its cause are often identical- an eclipse furnishes an example- what then is there to prevent other things too being identical with their cause and this cause being the essence of the thing? It must be so; and by this search after the cause the thing's essence is reached, for the essence of a thing is its cause. I am not here saying that the informing Idea is the cause of the thing- though this is true- but that the Idea itself, unfolded, reveals the cause inherent in it.

A thing of inactivity, even though alive, cannot include its own cause; but where could a Forming-Idea, a member of the Intellectual-Principle, turn in quest of its cause? We may be answered "In the Intellectual-Principle"; but the two are not distinct; the Idea is the Intellectual-Principle; and if that Principle must contain the Ideas complete, their cause must be contained in them. The Intellectual-Principle itself contains every cause of the things of its content; but these of its content are identically Intellectual-Principle, each of them Intellectual-Principle; none of them, thus, can lack its own cause; each springs into being carrying with it the reason of its being. No result of chance, each must rise complete with its cause; it is an integral and so includes the excellence bound up with the cause. This is how all participants in the Idea are put into possession of their cause.

In our universe, a coherent total of multiplicity, the several items are linked each to the other, and by the fact that it is an all every cause is included in it: even in the particular thing the part is discernibly related to the whole, for the parts do not come into being separately and successively but are mutually cause and caused at one and the same moment. Much more in the higher realm must all the singles exist for the whole and each for itself: if then that world is the conjoint reality of all, of an all not chance-ruled and not sectional, the cause There must include the causes: every item must hold, in its very nature, the uncaused possession of its cause; uncaused, independent and standing apart from cause, they must be self-contained, cause and all.

Further, since nothing There is chance-sprung, and the multiplicity in each comprehends the entire content, then the cause of every member can be named; the cause was present from the beginning, inherent, not a cause but a fact of the being; or, rather, cause and manner of being were one. What could an Idea have, as cause, over and above the Intellectual-Principle? It is a thought of that Principle and cannot, at that, be considered as anything but a perfect product. If it is thus perfect we cannot speak of anything in which it is lacking nor cite any reason for such lack. That thing must be present, and we can say why. The why is inherent, therefore, in the entity, that is to say in every thought and activity of the Intellectual-Principle. Take for example the Idea of Man; Man entire is found to contribute to it; he is in that Idea in all his fulness including everything that from the beginning belonged to Man. If Man were not complete There, so that there were something to be added to the Idea, that additional must belong to a derivative; but Man exists from eternity and must therefore be complete; the man born is the derivative.

(4) 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.

But perhaps we may think Substance validly defined as that which is not predicated of anything else. White and black are predicated of an object having one or other of these qualities; double presupposes something distinct from itself- we refer not to the half, but to the length of wood of which doubleness is affirmed. father qua father is a predicate; knowledge is predicated of the subject in whom the knowledge exists; space is the limit of something, time the measure of something. Fire, on the other hand, is predicated of nothing; wood as such is predicated of nothing; and so with man, Socrates, and the composite substance in general.

Equally the Substantial Form is never a predicate, since it never acts as a modification of anything. Form is not an attribute of Matter hence, is not predicable of Matter it is simply a constituent of the Couplement. On the other hand, the Form of a man is not different from the man himself .

Matter, similarly, is part of a whole, and belongs to something else only as to a whole and not as to a separate thing of which it is predicated. White, on the contrary, essentially belongs to something distinct from itself.

We conclude that nothing belonging to something else and predicated of it can be Substance. Substance is that which belongs essentially to itself, or, in so far as it is a part of the differentiated object, serves only to complete the Composite. Each or either part of the Composite belongs to itself, and is only affirmed of the Composite in a special sense: only qua part of the whole is it predicated of something else; qua individual it is never in its essential nature predicated of an external.

It may be claimed as a common element in Matter, Form and the Couplement that they are all substrates. But the mode in which Matter is the substrate of Form is different from that in which Form and the Couplement are substrates of their modifications.

And is it strictly true to say that Matter is the substrate of Form? Form is rather the completion which Matter's nature as pure potentiality demands.

Moreover, Form cannot be said to reside in Matter . When one thing combines with another to form a unity, the one does not reside in the other; both alike are substrates of a third: thus, Man and a man are substrates of their experiences, and are prior to their activities and consequents.

Substance, then, is that from which all other things proceed and to which they owe their existence; it is the centre of passivity and the source of action.

(8) This is the explanation of Plato's Triplicity, in the passage where he names as the Primals the Beings gathered about the King of All, and establishes a Secondary containing the Secondaries, and a Third containing the Tertiaries.

He teaches, also, that there is an author of the Cause, that is of the Intellectual-Principle, which to him is the Creator who made the Soul, as he tells us, in the famous mixing bowl. This author of the causing principle, of the divine mind, is to him the Good, that which transcends the Intellectual-Principle and transcends Being: often too he uses the term "The Idea" to indicate Being and the Divine Mind. Thus Plato knows the order of generation- from the Good, the Intellectual-Principle; from the Intellectual-Principle, the Soul. These teachings are, therefore, no novelties, no inventions of today, but long since stated, if not stressed; our doctrine here is the explanation of an earlier and can show the antiquity of these opinions on the testimony of Plato himself.

Earlier, Parmenides made some approach to the doctrine in identifying Being with Intellectual-Principle while separating Real Being from the realm of sense.

"Knowing and Being are one thing he says, and this unity is to him motionless in spite of the intellection he attributes to it: to preserve its unchanging identity he excludes all bodily movement from it; and he compares it to a huge sphere in that it holds and envelops all existence and that its intellection is not an outgoing act but internal. Still, with all his affirmation of unity, his own writings lay him open to the reproach that his unity turns out to be a multiplicity.

The Platonic Parmenides is more exact; the distinction is made between the Primal One, a strictly pure Unity, and a secondary One which is a One-Many and a third which is a One-and-many; thus he too is in accordance with our thesis of the Three Kinds.

(14) Another approach: Everything to which existence may be attributed is either one with its essence or distinct from it. Thus any given man is distinct from essential man though belonging to the order Man: a soul and a soul's essence are the same- that is, in case of soul pure and unmingled- Man as type is the same as man's essence; where the thing, man, and the essence are different, the particular man may be considered as accidental; but man, the essence, cannot be so; the type, Man, has Real Being. Now if the essence of man is real, not chanced or accidental, how can we think That to be accidental which transcends the order man, author of the type, source of all being, a principle more nearly simplex than man's being or being of any kind? As we approach the simplex, accident recedes; what is utterly simplex accident never touches at all.

Further we must remember what has been already said, that where there is true being, where things have been brought to reality by that Principle- and this is true of whatsoever has determined condition within the order of sense- all that reality is brought about in virtue of something emanating from the divine. By things of determined condition I mean such as contain, inbound with their essence, the reason of their being as they are, so that, later, an observer can state the use for each of the constituent parts- why the eye, why feet of such and such a kind to such and such a being- and can recognise that the reason for the production of each organ is inherent in that particular being and that the parts exist for each other. Why feet of a certain length? Because another member is as it is: because the face is as it is, therefore the feet are what they are: in a word the mutual determinant is mutual adaptation and the reason of each of the several forms is that such is the plan of man.

Thus the essence and its reason are one and the same. The constituent parts arise from the one source not because that source has so conceived each separately but because it has produced simultaneously the plan of the thing and its existence. This therefore is author at once of the existence of things and of their reasons, both produced at the one stroke. It is in correspondence with the things of process but far more nearly archetypal and authentic and in a closer relation with the Better, their source, than they can be.

Of things carrying their causes within, none arises at hazard or without purpose; this "So it happened to be" is applicable to none. All that they have comes from The Good; the Supreme itself, then, as author of reason, of causation, and of causing essence- all certainly lying far outside of chance- must be the Principle and as it were the examplar of things, thus independent of hazard: it is, the First, the Authentic, immune from chance, from blind effect and happening: God is cause of Himself; for Himself and of Himself He is what He is, the first self, transcendently The Self.

(4) If we had to ascertain the nature of body and the place it holds in the universe, surely we should take some sample of body, say stone, and examine into what constituents it may be divided. There would be what we think of as the substrate of stone, its quantity- in this case, a magnitude; its quality- for example, the colour of stone. As with stone, so with every other body: we should see that in this thing, body, there are three distinguishable characteristics- the pseudo-substance, the quantity, the quality- though they all make one and are only logically trisected, the three being found to constitute the unit thing, body. If motion were equally inherent in its constitution, we should include this as well, and the four would form a unity, the single body depending upon them all for its unity and characteristic nature.

The same method must be applied in examining the Intellectual Substance and the genera and first-principles of the Intellectual sphere.

But we must begin by subtracting what is peculiar to body, its coming-to-be, its sensible nature, its magnitude- that is to say, the characteristics which produce isolation and mutual separation. It is an Intellectual Being we have to consider, an Authentic Existent, possessed of a unity surpassing that of any sensible thing.

Now the wonder comes how a unity of this type can be many as well as one. In the case of body it was easy to concede unity-with-plurality; the one body is divisible to infinity; its colour is a different thing from its shape, since in fact they are separated. But if we take Soul, single, continuous, without extension, of the highest simplicity- as the first effort of the mind makes manifest- how can we expect to find multiplicity here too? We believed that the division of the living being into body and soul was final: body indeed was manifold, composite, diversified; but in soul we imagined we had found a simplex, and boldly made a halt, supposing that we had come to the limit of our course.

Let us examine this soul, presented to us from the Intellectual realm as body from the Sensible. How is its unity a plurality? How is its plurality a unity? Clearly its unity is not that of a composite formed from diverse elements, but that of a single nature comprising a plurality.

This problem attacked and solved, the truth about the genera comprised in Being will thereby, as we asserted, be elucidated also.

(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.

(14) The Reason, then, is the Mind's image, and Mind God's [image]; while Body is [the image] of the Form; and Form [the image] of the Soul. The subtlest part of Matter is, then, Air ; of Air, Soul; of Soul, Mind; and of Mind, God. And God surroundeth all and permeateth all; while Mind Surroundeth Soul, Soul Air, Air Matter. Necessity and Providence and Nature are instruments of Cosmos and of Matter's ordering; while of intelligible things each is Essence, and Sameness is their Essence. But of the bodies of the Cosmos each is many; for through possessiong Sameness, [these] composed bodies, though they do change from one into another of themselves, do natheless keep the incorruption of their Sameness.

(1) The matter which flows through its form (is) a cause by which the invisibility which exists through the powers [...] for them all, for [...], as they beget before them and destroy.

(8) And from the same Cause of all, are the higher and lower intellectual essences of the godlike angels; and those of the souls; and the natures of the whole Cosmos; all things whatsoever said to be either in others, or by reflection. Yea, even the all holy and most honoured Powers veritably being, and established, as it were, in the vestibule of the superessential Triad, are from It, and in It; and have the being and the godlike being; and after them, as regards Angels, the subordinate, subordinately, and the remotest, most remotely, but as regards ourselves, supermundanely. And the souls, and all the other beings, according to the same rule, have their being, and their well-being; and are, and are well; by having from the Pre-existing their being and their well-being. And in It are both being and well-being; and from It, beginning; and in It, guarded; and to It, terminated. And the prerogatives of being he distributes to the superior beings, which the Oracles call even eternal. But being itself never at any time fails all existing beings. And even self-existent being is from the Pre-existent, and of Him is being, and He is not of being;--and in Him is being, and He is not in being; and being possesses Him, and not He possesses being; and He is both age and beginning, and measure of being; being essentiating Source, and Middle and End, of pre-essence, and being and age and all things. And for this reason, by the Oracles, the veritably Pre-existing is represented under many forms, according to every conception of beings, and the "Was" and the "Is," and the "Will be," and the "Became," and the "Becomes," and the "Will become," are properly sung respecting Him. For all these, to those who think worthily of God, signify by every conception His being superessentially, and Cause in every way of things existing. For He is not this, but not that; nor is He in some way, but not in some other; but He is all things, as Cause of all, and containing and pre-holding in Himself all governments, all controls, of all existing things. And He is above all, as superessentially super-being before all. Wherefore, also, all things are predicated of Him and together, and He is none of them all; of every shape, of every kind, without form, without beauty, anticipating in Himself, beginnings and middles, and ends of things existing, irresistibly and preeminently; and shedding forth without flaw, (the light of) being to all, as beseems a One and super-united Cause. For, if our sun, at the same time that he is one and sheds a uniform light, renews the essences and qualities of sensible creatures, although they are many and various, and nourishes and guards, and perfects and distinguishes, and unites, and fosters, and makes to be productive, and increases, and transforms, and establishes, and makes to grow, and awakens, and gives life to all; and each of the whole, in a manner appropriate to itself, participates in the same and one sun; and the one sun anticipated in himself, uniformly, the causes of the many participants; much more with regard to the Cause of it and of all things, ought we to concede that It first presides over, as beseems One superessential Oneness, all the exemplars, of things existing; since He produces even essences, as beseems the egression from essence. But, we affirm that the exemplars are the methods in God, giving essence to things that be, and pre-existing uniformly, which theology calls predeterminations, and Divine and good wills, which define and produce things existing; according to which (predeterminations) the Superessential both predetermined and brought into existence everything that exists.

(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.

(3) How then do we go to work?

Let us begin by distinguishing Matter, Form, the Mixture of both, and the Attributes of the Mixture. The Attributes may be subdivided into those which are mere predicates, and those serving also as accidents. The accidents may be either inclusive or included; they may, further, be classified as activities, experiences, consequents.

Matter will be found common to all substances, not however as a genus, since it has no differentiae- unless indeed differentiae be ascribed to it on the ground of its taking such various forms as fire and air.

It may be held that Matter is sufficiently constituted a genus by the fact that the things in which it appears hold it in common, or in that it presents itself as a whole of parts. In this sense Matter will indeed be a genus, though not in the accepted sense of the term. Matter, we may remark, is also a single element, if the element as such is able to constitute a genus.

Further, if to a Form be added the qualification "bound up with, involved in Matter," Matter separates that Form from other Forms: it does not however embrace the whole of Substantial Form .

We may, again, regard Form as the creator of Substance and make the Reason-Principle of Substance dependent upon Form: yet we do not come thereby to an understanding of the nature of Substance.

We may, also, restrict Substance to the Composite. Matter and Form then cease to be substances. If they are Substance equally with the Composite, it remains to enquire what there is common to all three.

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.

The first three entities 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 , Time-during-which and Place-in-which become superfluous.

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.
