(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.

(56) The Head contains the five Senses, viz. Seeing, Hearing, Smelling, Tasting, and Feeling, wherein the Stars and Elements qualify, and therein exists the Sydereal, or Heavenly Starry or Astral and Natural Spirit in Men and Beasts; in this flow forth Good and Evil, for it is the House of the Stars.

(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;

(2) For by thine eyes thou mayest not conceive of anything, unless it be by the length and the breadth, the smallness and the greatness, the roundness and the squareness, the farness and the nearness, and the colour of it. And by thine ears, nought but noise or some manner of sound. By thine nose, nought but either stench or savour. And by thy taste, nought but either sour or sweet, salt or fresh, bitter or liking. And by thy feeling, nought but either hot or cold, hard or tender, soft or sharp. And truly, neither hath God nor ghostly things none of these qualities nor quantities. And therefore leave thine outward wits, and work not with them, neither within nor without: for all those that set them to be ghostly workers within, and ween that they should either hear, smell, or see, taste or feel, ghostly things, either within them or without, surely they be deceived, and work wrong against the course of nature.

(507) additional nature in order that the one may be able to hear and the other to be heard? Nothing of the sort. No, indeed, I replied; and the same is true of most, if not all, the other senses—you would not say that any of them requires such an addition? Certainly not. But you see that without the addition of some other nature there is no seeing or being seen? How do you mean? Sight being, as I conceive, in the eyes, and he who has eyes wanting to see; colour being also present in them, still unless there be a third nature specially adapted to the purpose, the owner of the eyes will see nothing and the colours will be invisible. Of what nature are you speaking? Of that which you term light, I replied. True, he said. Noble, then, is the bond which links together sight and visibility, and great beyond other bonds by no small difference of nature; for light is their bond, and light is no ignoble thing? Nay, he said, the reverse of ignoble. And which, I said, of the gods in heaven would you say was the lord of this element? Whose is that light which makes the eye to see perfectly and the visible to appear? You mean the sun, as you and all mankind say. May not the relation of sight to this deity be described as follows? How?

(23) A first principle is that the knowing of sensible objects is an act of the soul, or of the living conjoint, becoming aware of the quality of certain corporeal entities, and appropriating the ideas present in them.

This apprehension must belong either to the soul isolated, self-acting, or to soul in conjunction with some other entity.

Isolated, self-acting, how is it possible? Self-acting, it has knowledge of its own content, and this is not perception but intellection: if it is also to know things outside itself it can grasp them only in one of two ways: either it must assimilate itself to the external objects, or it must enter into relations with something that has been so assimilated.

Now as long as it remains self-centred it cannot assimilate: a single point cannot assimilate itself to an external line: even line cannot adapt itself to line in another order, line of the intellectual to line of the sensible, just as fire of the intellectual and man of the intellectual remain distinct from fire and man of the sensible. Even Nature, the soul-phase which brings man into being, does not come to identity with the man it shapes and informs: it has the faculty of dealing with the sensible, but it remains isolated, and, its task done, ignores all but the intellectual as it is itself ignored by the sensible and utterly without means of grasping it.

Suppose something visible lying at a distance: the soul sees it; now, admitting to the full that at first only the pure idea of the thing is seized- a total without discerned part- yet in the end it becomes to the seeing soul an object whose complete detail of colour and form is known: this shows that there is something more here than the outlying thing and the soul; for the soul is immune from experience; there must be a third, something not thus exempt; and it is this intermediate that accepts the impressions of shape and the like.

This intermediate must be able to assume the modifications of the material object so as to be an exact reproduction of its states, and it must be of the one elemental-stuff: it, thus, will exhibit the condition which the higher principle is to perceive; and the condition must be such as to preserve something of the originating object, and yet not be identical with it: the essential vehicle of knowledge is an intermediary which, as it stands between the soul and the originating object, will, similarly, present a condition midway between the two spheres, of sense and the intellectual-linking the extremes, receiving from one side to exhibit to the other, in virtue of being able to assimilate itself to each. As an instrument by which something is to receive knowledge, it cannot be identical with either the knower or the known: but it must be apt to likeness with both- akin to the external object by its power of being affected, and to the internal, the knower, by the fact that the modification it takes becomes an idea.

If this theory of ours is sound, bodily organs are necessary to sense-perception, as is further indicated by the reflection that the soul entirely freed of body can apprehend nothing in the order of sense.

The organ must be either the body entire or some member set apart for a particular function; thus touch for one, vision for another. The tools of craftsmanship will be seen to be intermediaries between the judging worker and the judged object, disclosing to the experimenter the particular character of the matter under investigation: thus a ruler, representing at once the straightness which is in the mind and the straightness of a plank, is used as an intermediary by which the operator proves his work.

Some questions of detail remain for consideration elsewhere: Is it necessary that the object upon which judgement or perception is to take place should be in contact with the organ of perception, or can the process occur across space upon an object at a distance? Thus, is the heat of a fire really at a distance from the flesh it warms, the intermediate space remaining unmodified; is it possible to see colour over a sheer blank intervening between the colour and the eye, the organ of vision reaching to its object by its own power?

For the moment we have one certainty, that perception of things of sense belongs to the embodied soul and takes place through the body.

(2) The Reader should not make himself blind through his Unbelief, and dull Apprehension; for here I bring in the whole or total Nature, with all her Children, for a Witness and Demonstration. And if thou art rational, then look round about thee, and view thyself; also consider thyself aright, and then thou wilt soon find from, or out of what Spirit I write.

(1) We undertook to discuss the question whether sight is possible in the absence of any intervening medium, such as air or some other form of what is known as transparent body: this is the time and place.

It has been explained that seeing and all sense-perception can occur only through the medium of some bodily substance, since in the absence of body the soul is utterly absorbed in the Intellectual Sphere. Sense-perception being the gripping not of the Intellectual but of the sensible alone, the soul, if it is to form any relationship of knowledge, or of impression, with objects of sense, must be brought in some kind of contact with them by means of whatever may bridge the gap.

The knowledge, then, is realized by means of bodily organs: through these, which are almost of one growth with it, being at least its continuations, it comes into something like unity with the alien, since this mutual approach brings about a certain degree of identity .

Admitting, then, that some contact with an object is necessary for knowing it, the question of a medium falls to the ground in the case of things identified by any form of touch; but in the case of sight- we leave hearing over for the present- we are still in doubt; is there need of some bodily substance between the eye and the illumined object?

No: such an intervening material may be a favouring circumstance, but essentially it adds nothing to seeing power. ! Dense bodies, such as clay, actually prevent sight; the less material the intervening substance is, the more clearly we see; the intervening substance, then, is a hindrance, or, if not that, at least not a help.

It will be objected that vision implies that whatever intervenes between seen and seer must first experience the object and be, as it were, shaped to it; we will be reminded that anyone facing to the object from the side opposite to ourselves sees it equally; we will be asked to deduce that if all the space intervening between seen and seer did not carry the impression of the object we could not receive it.

But all the need is met when the impression reaches that which is adapted to receive it; there is no need for the intervening space to be impressed. If it is, the impression will be of quite another order: the rod between the fisher's hand and the torpedo fish is not affected in the same way as the hand that feels the shock. And yet there too, if rod and line did not intervene, the hand would not be affected- though even that may be questioned, since after all the fisherman, we are told, is numbed if the torpedo merely lies in his net.

The whole matter seems to bring us back to that sympathy of which we have treated. If a certain thing is of a nature to be sympathetically affected by another in virtue of some similitude between them, then anything intervening, not sharing in that similitude, will not be affected, or at least not similarly. If this be so, anything naturally disposed to be affected will take the impression more vividly in the absence of intervening substance, even of some substance capable, itself, of being affected.

(2) For as the World’s illumined by the Sun, so is the mind of man illumined by that Light; nay, in [still] fuller measure. For whatsoever thing the Sun doth shine upon, it is anon, by interjection of the Earth or Moon, or by the intervention of the night, robbed of its light. But once the [Higher] Sense hath been commingled with the soul of man, there is at-onement from the happy union of the blending of their natures; so that minds of this kind are never more held fast in errors of the darkness. Wherefore, with reason have they said the [Higher] Senses are the souls of Gods; to which I add: not of all Gods, but of the great ones [only]; nay, even of the principles of these.

(508) Neither sight nor the eye in which sight resides is the sun? No. Yet of all the organs of sense the eye is the most like the sun? By far the most like. And the power which the eye possesses is a sort of effluence which is dispensed from the sun? Exactly. Then the sun is not sight, but the author of sight who is recognised by sight? True, he said. And this is he whom I call the child of the good, whom the good begat in his own likeness, to be in the visible world, in relation to sight and the things of sight, what the good is in the intellectual world in relation to mind and the things of mind: Will you be a little more explicit? he said. Why, you know, I said, that the eyes, when a person directs them towards objects on which the light of day is no longer shining, but the moon and stars only, see dimly, and are nearly blind; they seem to have no clearness of vision in them? Very true. But when they are directed towards objects on which the sun shines, they see clearly and there is sight in them? Certainly. And the soul is like the eye: when resting upon that on which truth and being shine, the soul perceives and understands, and is radiant with intelligence; but when turned towards the twilight of becoming and perishing, then she has opinion only, and goes blinking about, and is first of one opinion and then of another, and seems to have no intelligence? Just so.

(89) Open your Eyes, and consider your Selves: Man is made according to the Similitude, and out of the Power of God in his Ternary. Behold thy inward Man, and then thou wilt see it most plainly and clearly, if thou art not a Fool, and an irrational Beast; therefore observe,

(4) Within in thyself in nature be the powers of thy soul: the which be these three principal, Memory, Reason, and Will; and secondary, Imagination and Sensuality.

(3) Of all these genera, those [species] which are animal have [many] roots, which stretch from the above below, whereas those which are stationary —these from [one] living root send forth a wood of branching greenery up from below into the upper parts. Moreover, some of them are nourished with a two-fold form of food, while others with a single form. Twain are the forms of food—for soul and body, of which [all] animals consist. Their soul is nourished by the ever-restless motion of the World ; their bodies have their growth from foods [drawn] from the water and the earth of the inferior world. Spirit, with which they all are filled, being interblended with the rest, doth make them live; sense being added, and also reason in the case of man—which hath been given to man alone as a fifth part out of the æther. Of all the living things [God] doth adorn, extend, exalt, the sense of man alone unto the understanding of the Reason of Divinity. But since I am impressed to speak concerning Sense, I will a little further on set forth for you the sermon on this [point]; for that it is most holy, and [most] mighty, not less than in the Reason of Divinity itself. VII

(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.

(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.

(2) But as to Sense and all things similar, I will set forth the whole discourse when [I explain] concerning Spirit. For man is the sole animal that is twofold. One part of him is simple: the [man] “essential,” as say the Greeks, but which we call the “form of the Divine Similitude.” He also is fourfold: that which the Greeks call “hylic,” [but] which we call “cosmic”; of which is made the corporal part, in which is vestured what we just have said is the divine in man, —in which the godhead of the Mind alone, together with its kin, that is the Pure Mind’s senses, findeth home and rest, its self with its own self, as though shut in the body’s walls.

(3) For that, in order that a man should be complete in either part, observe that he hath been composed of elements of either part in sets of four;—with hands, and feet, both of them pairs, and with the other members of his body, by means of which he may do service to the lower (that is to say the terrene) world. And to these parts [are added other] four;—of sense, and soul, of memory, and foresight, by means of which he may become acquainted with the rest of things divine, and judge of them. Hence it is brought about that man investigates the differences and qualities, effects and quantities of things, with critical research; yet, as he is held back with the too heavy weight of body’s imperfection, he cannot properly descry the causes of the nature of [all] things which [really] are the true ones.

(24) The next question is whether perception is concerned only with need.

The soul, isolated, has no sense-perception; sensations go with the body; sensation itself therefore must occur by means of the body to which the sensations are due; it must be something brought about by association with the body.

Thus either sensation occurs in a soul compelled to follow upon bodily states- since every graver bodily experience reaches at last to soul- or sensation is a device by which a cause is dealt with before it becomes so great as actually to injure us or even before it has begun to make contact.

At this, sense-impressions would aim at utility. They may serve also to knowledge, but that could be service only to some being not living in knowledge but stupefied as the result of a disaster, and the victim of a Lethe calling for constant reminding: they would be useless to any being free from either need or forgetfulness. This This reflection enlarges the enquiry: it is no longer a question of earth alone, but of the whole star-system, all the heavens, the kosmos entire. For it would follow that, in the sphere of things not exempt from modification, sense-perception would occur in every part having relation to any other part: in a whole, however- having relation only to itself, immune, universally self-directed and self-possessing- what perception could there be?

Granted that the percipient must act through an organ and that this organ must be different from the object perceived, then the universe, as an All, can have no organ distinct from object: it can have self-awareness, as we have; but sense-perception, the constant attendant of another order, it cannot have.

Our own apprehension of any bodily condition apart from the normal is the sense of something intruding from without: but besides this, we have the apprehension of one member by another; why then should not the All, by means of what is stationary in it, perceive that region of itself which is in movement, that is to say the earth and the earth's content?

Things of earth are certainly affected by what passes in other regions of the All; what, then, need prevent the All from having, in some appropriate way, the perception of those changes? In addition to that self-contemplating vision vested in its stationary part, may it not have a seeing power like that of an eye able to announce to the All-Soul what has passed before it? Even granted that it is entirely unaffected by its lower, why, still, should it not see like an eye, ensouled as it is, all lightsome?

Still: "eyes were not necessary to it," we read. If this meant simply that nothing is left to be seen outside of the All, still there is the inner content, and there can be nothing to prevent it seeing what constitutes itself: if the meaning is that such self-vision could serve to no use, we may think that it has vision not as a main intention for vision's sake but as a necessary concomitant of its characteristic nature; it is difficult to conceive why such a body should be incapable of seeing.

(65) For in these Five Qualities rise up the Seeing, Smelling, Tasting and Feeling, and so a Rational Spirit comes to be. As
