(6) We return, then, to the question whether there could be light if there were no air, the sun illuminating corporeal surfaces across an intermediate void which, as things are, takes the light accidentally by the mere fact of being in the path. Supposing air to be the cause of the rest of things being thus affected, the substantial existence of light is due to the air; light becomes a modification of the air, and of course if the thing to be modified did not exist neither could be modification.

The fact is that primarily light is no appanage of air, and does not depend upon the existence of air: it belongs to every fiery and shining body, it constitutes even the gleaming surface of certain stones.

Now if, thus, it enters into other substances from something gleaming, could it exist in the absence of its container?

There is a distinction to be made: if it is a quality, some quality of some substance, then light, equally with other qualities, will need a body in which to lodge: if, on the contrary, it is an activity rising from something else, we can surely conceive it existing, though there be no neighbouring body but, if that is possible, a blank void which it will overleap and so appear on the further side: it is powerful, and may very well pass over unhelped. If it were of a nature to fall, nothing would keep it up, certainly not the air or anything that takes its light; there is no reason why they should draw the light from its source and speed it onwards.

Light is not an accidental to something else, requiring therefore to be lodged in a base; nor is it a modification, demanding a base in which the modification occurs: if this were so, it would vanish when the object or substance disappeared; but it does not; it strikes onward; so, too it would always have its movement.

But movement, where?

Is space, pure and simple, all that is necessary?

With unchecked motion of the light outward, the material sun will be losing its energy, for the light is its expression.

Perhaps; and we may gather that the light never was an appanage of anything, but is the expressive Act proceeding from a base but not seeking to enter into a base, though having some operation upon any base that may be present.

Life is also an Act, the Act of the soul, and it remains so when anything- the human body, for instance- comes in its path to be affected by it; and it is equally an Act though there be nothing for it to modify: surely this may be true of light, one of the Acts of whatever luminary source there be . Certainly light is not brought into being by the dark thing, air, which on the contrary tends to gloom it over with some touch of earth so that it is no longer the brilliant reality: as reasonable to talk of some substance being sweet because it is mixed with something bitter.

If we are told that light is a mode of the air, we answer that this would necessarily imply that the air itself is changed to produce the new mode; in other words, its characteristic darkness must change into non-darkness; but we know that the air maintains its character, in no wise affected: the modification of a thing is an experience within that thing itself: light therefore is not a modification of the air, but a self-existent in whose path the air happens to be present.

On this point we need dwell no longer; but there remains still a question.

(11) I think, therefore, that those ancient sages, who sought to secure the presence of divine beings by the erection of shrines and statues, showed insight into the nature of the All; they perceived that, though this Soul is everywhere tractable, its presence will be secured all the more readily when an appropriate receptacle is elaborated, a place especially capable of receiving some portion or phase of it, something reproducing it, or representing it, and serving like a mirror to catch an image of it.

It belongs to the nature of the All to make its entire content reproduce, most felicitously, the Reason-Principles in which it participates; every particular thing is the image within matter of a Reason-Principle which itself images a pre-material Reason-Principle: thus every particular entity is linked to that Divine Being in whose likeness it is made, the divine principle which the soul contemplated and contained in the act of each creation. Such mediation and representation there must have been since it was equally impossible for the created to be without share in the Supreme, and for the Supreme to descend into the created.

The Intellectual-Principle in the Supreme has ever been the sun of that sphere- let us accept that as the type of the creative Logos- and immediately upon it follows the Soul depending from it, stationary Soul from stationary Intelligence. But the Soul borders also upon the sun of this sphere, and it becomes the medium by which all is linked to the overworld; it plays the part of an interpreter between what emanates from that sphere down to this lower universe, and what rises- as far as, through soul, anything can- from the lower to the highest.

Nothing, in fact, is far away from anything; things are not remote: there is, no doubt, the aloofness of difference and of mingled natures as against the unmingled; but selfhood has nothing to do with spatial position, and in unity itself there may still be distinction.

These Beings are divine in virtue of cleaving to the Supreme, because, by the medium of the Soul thought of as descending they remain linked with the Primal Soul, and through it are veritably what they are called and possess the vision of the Intellectual Principle, the single object of contemplation to that soul in which they have their being.

(2) Invoking then Jesus, the Paternal Light, the Real, the True, "which lighteth every man coming into the world," "through Whom we have access to the Father," Source of Light, let us aspire, as far as is attainable, to the illuminations handed down by our fathers in the most sacred Oracles, and let us gaze, as we may, upon the Hierarchies of the Heavenly Minds manifested by them symbolically for our instruction. And when we have received, with immaterial and unflinching mental eyes, the gift of Light, primal and super-primal, of the supremely Divine Father, which manifests to us the most blessed Hierarchies of the Angels in types and symbols, let us then, from it, be elevated to its simple splendour. For it never loses its own unique inwardness, but multiplied and going forth, as becomes its goodness, for an elevating and unifying blending of the objects of its care, remains firmly and solitarily centred within itself in its unmoved sameness; and raises, according to their capacity, those who lawfully aspire to it, and makes them one, after the example of its own unifying Oneness. For it is not possible that the supremely Divine Ray should otherwise illuminate us, except so far as it is enveloped, for the purpose of instruction, in variegated sacred veils, and arranged naturally and appropriately, for such as we are, by paternal forethought.

(3) Ever illuminated, receiving light unfailing, the All-Soul imparts it to the entire series of later Being which by this light is sustained and fostered and endowed with the fullest measure of life that each can absorb. It may be compared with a central fire warming every receptive body within range.

Our fire, however, is a thing of limited scope: given powers that have no limitation and are never cut off from the Authentic Existences, how imagine anything existing and yet failing to receive from them?

It is of the essence of things that each gives of its being to another: without this communication, The Good would not be Good, nor the Intellectual-Principle an Intellective Principle, nor would Soul itself be what it is: the law is, "some life after the Primal Life, a second where there is a first; all linked in one unbroken chain; all eternal; divergent types being engendered only in the sense of being secondary."

In other words, things commonly described as generated have never known a beginning: all has been and will be. Nor can anything disappear unless where a later form is possible: without such a future there can be no dissolution.

If we are told that there is always Matter as a possible term, we ask why then should not Matter itself come to nothingness. If we are told it may, then we ask why it should ever have been generated. If the answer comes that it had its necessary place as the ultimate of the series, we return that the necessity still holds.

With Matter left aside as wholly isolated, the Divine Beings are not everywhere but in some bounded place, walled off, so to speak; if that is not possible, Matter itself must receive the Divine light .

(7) We can scarcely do better, in fine, than follow Plato.

Thus:

In the universe as a whole there must necessarily be such a degree of solidity, that is to say, of resistance, as will ensure that the earth, set in the centre, be a sure footing and support to the living beings moving over it, and inevitably communicate something of its own density to them: the earth will possess coherence by its own unaided quality, but visibility by the presence of fire: it will contain water against the dryness which would prevent the cohesion of its particles; it will hold air to lighten its bulky matters; it will be in contact with the celestial fire- not as being a member of the sidereal system but by the simple fact that the fire there and our earth both belong to the ordered universe so that something of the earth is taken up by the fire as something of the fire by the earth and something of everything by everything else.

This borrowing, however, does not mean that the one thing taking-up from the other enters into a composition, becoming an element in a total of both: it is simply a consequence of the kosmic fellowship; the participant retains its own being and takes over not the thing itself but some property of the thing, not air but air's yielding softness, not fire but fire's incandescence: mixing is another process, a complete surrender with a resultant compound not, as in this case, earth- remaining earth, the solidity and density we know- with something of fire's qualities superadded.

We have authority for this where we read:

"At the second circuit from the earth, God kindled a light": he is speaking of the sun which, elsewhere, he calls the all-glowing and, again, the all-gleaming: thus he prevents us imagining it to be anything else but fire, though of a peculiar kind; in other words it is light, which he distinguishes from flame as being only modestly warm: this light is a corporeal substance but from it there shines forth that other "light" which, though it carries the same name, we pronounce incorporeal, given forth from the first as its flower and radiance, the veritable "incandescent body." Plato's word earthy is commonly taken in too depreciatory a sense: he is thinking of earth as the principle of solidity; we are apt to ignore his distinctions and think of the concrete clay.

Fire of this order, giving forth this purest light, belongs to the upper realm, and there its seat is fixed by nature; but we must not, on that account, suppose the flame of earth to be associated with the beings of that higher sphere.

No: the flame of this world, once it has attained a certain height, is extinguished by the currents of air opposed to it. Moreover, as it carries an earthy element on its upward path, it is weighed downwards and cannot reach those loftier regions. It comes to a stand somewhere below the moon- making the air at that point subtler- and its flame, if any flame can persist, is subdued and softened, and no longer retains its first intensity, but gives out only what radiance it reflects from the light above.

And it is that loftier light- falling variously upon the stars; to each in a certain proportion- that gives them their characteristic differences, as well in magnitude as in colour; just such light constitutes also the still higher heavenly bodies which, however, like clear air, are invisible because of the subtle texture and unresisting transparency of their material substance and also by their very distance.

(4) It is, then, possible to frame in one's mind good contemplations from everything, and to depict, from things material, the aforesaid dissimilar similitudes, both for the intelligible and the intelligent; since the intelligent hold in a different fashion things which are attributed to things sensible differently. For instance, appetite, in the irrational creatures, takes its rise in the passions, and their movement, which takes the form of appetite, is full of all kinds of unreasonableness. But with regard to the intelligent, we must think of the appetite in another fashion, as denoting, according to my judgment, their manly style, and their determined persistence in their Godlike and unchangeable steadfastness. In like manner we say, with regard to the irrational creatures, that lust is a certain uncircumspect and earthly passionate attachment, arising incontinently from an innate movement, or intimacy in things subject to change, and the irrational supremacy of the bodily desire, which drives the whole organism towards the object of sensual inclination. But when we attribute "lust" to spiritual beings, by clothing them with dissimilar similitudes, we must think that it is a Divine love of the immaterial, above expression and thought, and the inflexible and determined longing for the supernally pure and passionless contemplation, and for the really perpetual and intelligible fellowship in that pure and most exalted splendour, and in the abiding and beautifying comeliness. And 'incontinence' we may take for the persistent and inflexible, which nothing can repulse, on account of the pure and changeless love for the Divine beauty, and the whole tendency towards the really desired. But with regard to the irrational living beings, or soulless matter, we appropriately call their irrationality and want of sensible perception a deprivation of reason and sensible perception. And with regard to the immaterial and intelligent beings, we reverently acknowledge their superiority, as supermundane beings, over our discursive and bodily reason, and the material perception of the senses which is alien to the incorporeal Minds. It is, then, permissible to depict forms, which are not discordant, to the celestial beings, even from portions of matter which are the least honourable, since even it, having had its beginning from the Essentially Beautiful, has throughout the whole range of matter some echoes of the intellectual comeliness; and it is possible through these to be led to the immaterial archetypes--things most similar being taken, as has been said, dissimilarly, and the identities being denned, not in the same way, but harmoniously, and appropriately, as regards the intellectual and sensible beings.

(7) Consider the act of ocular vision:

There are two elements here; there is the form perceptible to the sense and there is the medium by which the eye sees that form. This medium is itself perceptible to the eye, distinct from the form to be seen, but the cause of the seeing; it is perceived at the one stroke in that form and on it and, hence, is not distinguished from it, the eye being held entirely by the illuminated object. When on the contrary this medium presents itself alone it is seen directly- though even then actual sight demands some solid base; there must be something besides the medium which, unless embracing some object, eludes perception; thus the light inherent to the sun would not be perceived but for the solidity of the mass. If it is objected that the sun is light entire, this would only be a proof of our assertion: no other visible form will contain light which must, then, have no other property than that of visibility, and in fact all other visible objects are something more than light alone.

So it is with the act of vision in the Intellectual Principle.

This vision sees, by another light, the objects illuminated by the First Principle: setting itself among them, it sees veritably; declining towards the lower Nature, that upon which the light from above rests, it has less of that vision. Passing over the visible and looking to the medium by which it sees, then it holds the Light and the source of Light.

But since the Intellectual-Principle is not to see this light as something external we return to our analogy; the eye is not wholly dependent upon an outside and alien light; there is an earlier light within itself, a more brilliant, which it sees sometimes in a momentary flash. At night in the darkness a gleam leaps from within the eye: or again we make no effort to see anything; the eyelids close; yet a light flashes before us; or we rub the eye and it sees the light it contains. This is sight without the act, but it is the truest seeing, for it sees light whereas its other objects were the lit not the light.

It is certainly thus that the Intellectual-Principle, hiding itself from all the outer, withdrawing to the inmost, seeing nothing, must have its vision- not of some other light in some other thing but of the light within itself, unmingled, pure, suddenly gleaming before it;

(11) Let us affirm, then, that the goodness of the Divine Blessedness is always in the same condition and manner, unfolding the beneficent rays of its own light upon all the intellectual visions without grudging. Should, then, the self-choosing self-sufficiency of the contemplators either turn away from the light contemplated, by closing, through love of evil, the faculties for enlightenment naturally implanted within it, it would be separated from the light present to it, not turned away, but shining upon it when shortsighted and turning its face from light generously running to it; or should it overstep the bounds of the visible given to it in due proportion, and rashly undertake to gaze upon the rays superior to its vision, the light indeed will do nothing beyond its proper functions, but it, by imperfectly approaching thing's perfect, would not attain to things unsuitable, and, by stupidly disregarding the due proportion, would fail through its own fault. But, as I said, the Divine Light is always unfolded beneficently to the intellectual visions, and it is possible for them to seize it when present, and always being most ready for the distribution of things appropriate, in a manner becoming God. To this imitation the divine Hierarch is fashioned, unfolding to all, without grudging, the luminous rays of his inspired teaching, and, after the Divine example, being most ready to enlighten the proselyte, neither using a grudging nor an unholy wrath for former back-slidings or excess, but, after the example of God, always enlightening by his conducting light those who approach him, as becomes a Hierarch, in fitness, and order, and in proportion to the aptitude of each for holy things.

(4) But what slipped from our view in the midst of our discourse, the Good is Cause of the celestial movements in their commencements and terminations, of their not increasing, not diminishing, and completely changeless, course, and of the noiseless movements, if one may so speak, of the vast celestial transit, and of the astral orders, and the beauties and lights, and stabilities, and the progressive swift motion of certain stars, and of the periodical return of the two luminaries, which the Oracles call "great," from the same to the same quarter, after which our days and nights being marked, and months and years being measured, mark and number and arrange and comprehend the circular movements of time and things temporal. But, what would any one say of the very ray of the sun? For the light is from the Good, and an image of the Goodness, wherefore also the Good is celebrated under the name of Light; as in a portrait the original is manifested. For, as the goodness of the Deity, beyond all, permeates from the highest and most honoured substances even to the lowest, and yet is above all, neither the foremost outstripping its superiority, nor the things below eluding its grasp, but it both enlightens all that are capable, and forms and enlivens, and grasps, and perfects, and is measure of things existing, and age, and number, and order, and grasp, and cause, and end; so, too, the brilliant likeness of the Divine Goodness, this our great sun, wholly bright and ever luminous, as a most distant echo of the Good, both enlightens whatever is capable of participating in it, and possesses the light in the highest degree of purity, unfolding to the visible universe, above and beneath, the splendours of its own rays, and if anything does not participate in them, this is not owing to the inertness or deficiency of its distribution of light, but is owing to the inaptitude for light-reception of the things which do not unfold themselves for the participation of light. No doubt the ray passing over many things in such condition, enlightens the things after them, and there is no visible thing which it does not reach, with the surpassing greatness of its own splendour. Further also, it contributes to the generation of sensible bodies, and moves them to life, and nourishes, and increases, and perfects, and purifies and renews; and the light is both measure and number of hours, days, and all our time. For it is the light itself, even though it was then without form, which the divine Moses declared to have fixed that first Triad of our days. And, just as Goodness turns all things to Itself, and is chief collector of things scattered, as One-springing and One-making Deity, and all things aspire to It, as Source and Bond and End, and it is the Good, as the Oracles say, from Which all things subsisted, and are being brought into being by an all-perfect Cause; and in Which all things consisted, as guarded and governed in an all-controlling route; and to Which all things are turned, as to their own proper end; and to Which all aspire --the intellectual and rational indeed, through knowledge, and the sensible through the senses, and those bereft of sensible perception by the innate movement of the aspiration after life, and those without life, and merely being, by their aptitude for mere substantial participation; after the same method of its illustrious original, the light also collects and turns to itself all things existing--things with sight -- things with motion--things enlightened--things heated--things wholly held together by its brilliant splendours--whence also, Helios, because it makes all things altogether (ἀολλῆ), and collects things scattered. And all creatures, endowed with sensible perceptions, aspire to it, as aspiring either to see, or to be moved and enlightened, and heated, and to be wholly held together by the light. By no means do I affirm, after the statement of antiquity, that as being God and Creator of the universe, the sun, by itself, governs the luminous world, but that the invisible things of God are clearly seen from the foundation of the world, being understood by the things that are made, even His eternal power and Deity.

(3) But if any one should blame the descriptions as being incongruous, by saying that it is shameful to attribute shapes so repugnant to the Godlike and most holy Orders, it is enough to reply that the method of Divine revelation is twofold; one, indeed, as is natural, proceeding through likenesses that are similar, and of a sacred character, but the other, through dissimilar forms, fashioning them into entire unlikeness and incongruity. No doubt, the mystical traditions of the revealing Oracles sometimes extol the august Blessedness of the super-essential Godhead, as Word, and Mind, and Essence, manifesting its God-becoming expression and wisdom, both as really being Origin, and true Cause of the origin of things being, and they describe It as light, and call it life. While such sacred descriptions are more reverent, and seem in a certain way to be superior to the material images, they yet, even thus, in reality fall short of the supremely Divine similitude. For It is above every essence and life. No light, indeed, expresses its character, and every description and mind incomparably fall short of Its similitude. But at other times its praises are supermundanely sung, by the Oracles themselves, through dissimilar revelations, when they affirm that it is invisible, and infinite, and incomprehensible; and when there is signified, not what it is, but what it is not. For this, as I think, is more appropriate to It, since, as the secret and sacerdotal tradition taught, we rightly describe its non-relationship to things created, but we do not know its superessential, and inconceivable, and unutterable indefinability. If, then, the negations respecting things Divine are true, but the affirmations are inharmonious, the revelation as regards things invisible, through dissimilar representations, is more appropriate to the hiddenness of things unutterable. Thus the sacred descriptions of the Oracles honour, and do not expose to shame, the Heavenly Orders, when they make them known by dissimilar pictorial forms, and demonstrate through these their supermundane superiority over all. material things. And I do not suppose that any sensible man will gainsay that the incongruous elevate our mind more than the similitudes; for there is a likelihood, with regard to the more sublime representations of heavenly things, that we should be led astray, so as to think that the Heavenly Beings are certain creatures with the appearance of gold, and certain men with the appearance of light, and glittering like lightning, handsome, clothed in bright shining raiment, shedding forth innocuous flame, and so with regard to all the other shapes and appropriate forms, with which the Word of God has depicted the Heavenly Minds. In order that men might not suffer from this, by thinking they are nothing more exalted than their beau tiful appearance, the elevating wisdom of the pious theologians reverently conducts to the incongruous dissimilarities, not permitting our earthly part to rest fixed in the base images, but urging the upward tendency of the soul, and goading it by the unseemliness of the phrases (to see) that it belongs neither to lawful nor seeming truth, even for the most earthly conceptions, that the most heavenly and Divine visions are actually like things so base. Further also this must particularly be borne in mind, that not even one of the things existing is altogether deprived of participation in the beautiful, since, as is evident and the truth of the Oracles affirms, all things are very beautiful.

(7) Our investigation may be furthered by enquiring: Whether light finally perishes or simply returns to its source.

If it be a thing requiring to be caught and kept, domiciled within a recipient, we might think of it finally passing out of existence: if it be an Act not flowing out and away- but in circuit, with more of it within than is in outward progress from the luminary of which it is the Act- then it will not cease to exist as long as that centre is in being. And as the luminary moves, the light will reach new points- not in virtue of any change of course in or out or around, but simply because the act of the luminary exists and where there is no impediment is effective. Even if the distance of the sun from us were far greater than it is, the light would be continuous all that further way, as long as nothing checked or blocked it in the interval.

We distinguish two forms of activity; one is gathered within the luminary and is comparable to the life of the shining body; this is the vaster and is, as it were, the foundation or wellspring of all the act; the other lies next to the surface, the outer image of the inner content, a secondary activity though inseparable from the former. For every existent has an Act which is in its likeness: as long as the one exists, so does the other; yet while the original is stationary the activity reaches forth, in some things over a wide range, in others less far. There are weak and faint activities, and there are some, even, that do not appear; but there are also things whose activities are great and far-going; in the case of these the activity must be thought of as being lodged, both in the active and powerful source and in the point at which it settles. This may be observed in the case of an animal's eyes where the pupils gleam: they have a light which shows outside the orbs. Again there are living things which have an inner fire that in darkness shines out when they expand themselves and ceases to ray outward when they contract: the fire has not perished; it is a mere matter of it being rayed out or not.

But has the light gone inward?

No: it is simply no longer on the outside because the fire is no longer outward going but has withdrawn towards the centre.

But surely the light has gone inward too?

No: only the fire, and when that goes inward the surface consists only of the non-luminous body; the fire can no longer act towards the outer.

The light, then, raying from bodies is an outgoing activity of a luminous body; the light within luminous bodies- understand; such as are primarily luminous- is the essential being embraced under the idea of that body. When such a body is brought into association with Matter, its activity produces colour: when there is no such association, it does not give colour- it gives merely an incipient on which colour might be formed- for it belongs to another being with which it retains its link, unable to desert from it, or from its activity.

And light is incorporeal even when it is the light of a body; there is therefore no question, strictly speaking, of its withdrawal or of its being present- these terms do not apply to its modes- and its essential existence is to be an activity. As an example: the image upon a mirror may be described as an activity exercised by the reflected object upon the potential recipient: there is no outgoing from the object ; it is simply that, as long as the object stands there, the image also is visible, in the form of colour shaped to a certain pattern, and when the object is not there, the reflecting surface no longer holds what it held when the conditions were favourable.

So it is with the soul considered as the activity of another and prior soul: as long as that prior retains its place, its next, which is its activity, abides.

But what of a soul which is not an activity but the derivative of an activity- as we maintained the life-principle domiciled in the body to be- is its presence similar to that of the light caught and held in material things?

No; for in those things the colour is due to an actual intermixture of the active element ; whereas the life-principle of the body is something that holds from another soul closely present to it.

But when the body perishes- by the fact that nothing without part in soul can continue in being- when the body is perishing, no longer supported by that primal life-giving soul, or by the presence of any secondary phase of it, it is clear that the life-principle can no longer remain; but does this mean that the life perishes?

No; not even it; for it, too, is an image of that first out-shining; it is merely no longer where it was.

(4) Besides, if rarity were of this dimness The cause thou askest, either through and through This planet thus attenuate were of matter, Or else, as in a body is apportioned The fat and lean, so in like manner this Would in its volume interchange the leaves. Were it the former, in the sun's eclipse It would be manifest by the shining through Of light, as through aught tenuous interfused. This is not so; hence we must scan the other, And if it chance the other I demolish, Then falsified will thy opinion be. But if this rarity go not through and through, There needs must be a limit, beyond which Its contrary prevents the further passing, And thence the foreign radiance is reflected, Even as a colour cometh back from glass, The which behind itself concealeth lead. Now thou wilt say the sunbeam shows itself More dimly there than in the other parts, By being there reflected farther back. From this reply experiment will free thee If e'er thou try it, which is wont to be The fountain to the rivers of your arts.
