(25) But the organ is not the only requisite to vision or to perception of any kind: there must be a state of the soul inclining it towards the sphere of sense.

Now it is the soul's character to be ever in the Intellectual sphere, and even though it were apt to sense-perception, this could not accompany that intention towards the highest; to ourselves when absorbed in the Intellectual, vision and the other acts of sense are in abeyance for the time; and, in general, any special attention blurs every other. The desire of apprehension from part to part- a subject examining itself- is merely curiosity even in beings of our own standing, and, unless for some definite purpose, is waste of energy: and the desire to apprehend something external- for the sake of a pleasant sight- is the sign of suffering or deficiency.

Smelling, tasting flavours may perhaps be described as mere accessories, distractions of the soul, while seeing and hearing would belong to the sun and the other heavenly bodies as incidentals to their being. This would not be unreasonable if seeing and hearing are means by which they apply themselves to their function.

But if they so apply themselves, they must have memory; it is impossible that they should have no remembrance if they are to be benefactors, their service could not exist without memory.

(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;

(4) But there is the question of the linked light that must relate the visual organ to its object.

Now, firstly: since the intervening air is not necessary- unless in the purely accidental sense that air may be necessary to light- the light that acts as intermediate in vision will be unmodified: vision depends upon no modification whatever. This one intermediate, light, would seem to be necessary, but, unless light is corporeal, no intervening body is requisite: and we must remember that intervenient and borrowed light is essential not to seeing in general but to distant vision; the question whether light absolutely requires the presence of air we will discuss later. For the present one matter must occupy us:

If, in the act of vision, that linked light becomes ensouled, if the soul or mind permeates it and enters into union with it, as it does in its more inward acts such as understanding- which is what vision really is- then the intervening light is not a necessity: the process of seeing will be like that of touch; the visual faculty of the soul will perceive by the fact of having entered into the light; all that intervenes remains unaffected, serving simply as the field over which the vision ranges.

This brings up the question whether the sight is made active over its field by the sheer presence of a distance spread before it, or by the presence of a body of some kind within that distance.

If by the presence of such a body, then there will be vision though there be no intervenient; if the intervenient is the sole attractive agent, then we are forced to think of the visible object as being a Kind utterly without energy, performing no act. But so inactive a body cannot be: touch tells us that, for it does not merely announce that something is by and is touched: it is acted upon by the object so that it reports distinguishing qualities in it, qualities so effective that even at a distance touch itself would register them but for the accidental that it demands proximity.

We catch the heat of a fire just as soon as the intervening air does; no need to wait for it to be warmed: the denser body, in fact, takes in more warmth than the air has to give; in other words, the air transmits the heat but is not the source of our warmth.

When on the one side, that of the object, there is the power in any degree of an outgoing act, and on the other, that of the sight, the capability of being acted upon, surely the object needs no medium through which to be effective upon what it is fully equipped to affect: this would be needing not a help but a hindrance.

Or, again, consider the Dawn: there is no need that the light first flood the air and then come to us; the event is simultaneous to both: often, in fact, we see when the light is not as yet round our eyes at all but very far off, before, that is, the air has been acted upon: here we have vision without any modified intervenient, vision before the organ has received the light with which it is to be linked.

It is difficult to reconcile with this theory the fact of seeing stars or any fire by night.

If the percipient mind or soul remains within itself and needs the light only as one might need a stick in the hand to touch something at a distance, then the perception will be a sort of tussle: the light must be conceived as something thrusting, something aimed at a mark, and similarly, the object, considered as an illuminated thing, must be conceived to be resistant; for this is the normal process in the case of contact by the agency of an intervenient.

Besides, even on this explanation, the mind must have previously been in contact with the object in the entire absence of intervenient; only if that has happened could contact through an intervenient bring knowledge, a knowledge by way of memory, and, even more emphatically, by way of reasoned comparison : but this process of memory and comparison is excluded by the theory of first knowledge through the agency of a medium.

Finally, we may be told that the impinging light is modified by the thing to be seen and so becomes able to present something perceptible before the visual organ; but this simply brings us back to the theory of an intervenient changed midway by the object, an explanation whose difficulties we have already indicated.

(107) Rightly therefore Plato "accustoms the best natures to attain to that study which formerly we said was the highest, both to see the good and to accomplish that ascent. And this, as appears, is not the throwing of the potsherds; but the turning round of the soul from a nocturnal day to that which is a true return to that which really is, which we shall assert to be the true philosophy." Such as are partakers of this he judges to belong to the golden race, when he says: "Ye are all brethren; and those who are of the golden race are most capable of judging most accurately in every respect."

(9) And this inner vision, what is its operation?

Newly awakened it is all too feeble to bear the ultimate splendour. Therefore the Soul must be trained- to the habit of remarking, first, all noble pursuits, then the works of beauty produced not by the labour of the arts but by the virtue of men known for their goodness: lastly, you must search the souls of those that have shaped these beautiful forms.

But how are you to see into a virtuous soul and know its loveliness?

Withdraw into yourself and look. And if you do not find yourself beautiful yet, act as does the creator of a statue that is to be made beautiful: he cuts away here, he smoothes there, he makes this line lighter, this other purer, until a lovely face has grown upon his work. So do you also: cut away all that is excessive, straighten all that is crooked, bring light to all that is overcast, labour to make all one glow of beauty and never cease chiselling your statue, until there shall shine out on you from it the godlike splendour of virtue, until you shall see the perfect goodness surely established in the stainless shrine.

When you know that you have become this perfect work, when you are self-gathered in the purity of your being, nothing now remaining that can shatter that inner unity, nothing from without clinging to the authentic man, when you find yourself wholly true to your essential nature, wholly that only veritable Light which is not measured by space, not narrowed to any circumscribed form nor again diffused as a thing void of term, but ever unmeasurable as something greater than all measure and more than all quantity- when you perceive that you have grown to this, you are now become very vision: now call up all your confidence, strike forward yet a step- you need a guide no longer- strain, and see.

This is the only eye that sees the mighty Beauty. If the eye that adventures the vision be dimmed by vice, impure, or weak, and unable in its cowardly blenching to see the uttermost brightness, then it sees nothing even though another point to what lies plain to sight before it. To any vision must be brought an eye adapted to what is to be seen, and having some likeness to it. Never did eye see the sun unless it had first become sunlike, and never can the soul have vision of the First Beauty unless itself be beautiful.

Therefore, first let each become godlike and each beautiful who cares to see God and Beauty. So, mounting, the Soul will come first to the Intellectual-Principle and survey all the beautiful Ideas in the Supreme and will avow that this is Beauty, that the Ideas are Beauty. For by their efficacy comes all Beauty else, but the offspring and essence of the Intellectual-Being. What is beyond the Intellectual-Principle we affirm to be the nature of Good radiating Beauty before it. So that, treating the Intellectual-Kosmos as one, the first is the Beautiful: if we make distinction there, the Realm of Ideas constitutes the Beauty of the Intellectual Sphere; and The Good, which lies beyond, is the Fountain at once and Principle of Beauty: the Primal Good and the Primal Beauty have the one dwelling-place and, thus, always, Beauty's seat is There.
