(6) Rā was speaking with Amhauf, and a blindness came upon him

(9) The eye (sight) departed, and having been absent for a year, it came round and said: 'How have you been able to live without me?' They replied: 'Like blind people, not seeing, but breathing with the breath, speaking with the tongue, hearing with the ear, thinking with the mind. Thus we lived.' Then the eye went back.

(6) The Eye went off. Having remained away a year, it came back and said: ' How have you been able to live without me?' They said: ' As the blind, not seeing with the eye, but breathing with breath, speaking with speech, hearing with the ear, knowing with the mind, procreating with semen. Thus have we lived.' The eye entered in.

(47) In my own faculties or powers I am as blind a man as ever was, and am able to do nothing; but in the spirit of God my innate [regenerated] spirit seeth through ALL, though not always with long stay or continuance; but only when the spirit of God's love breaketh through my spirit, then is the animated or soulish birth or geniture and the Deity one being, one comprehensibility, and one light.

(12) Our soul indeed is ill because she dwells in a house of poverty, while matter strikes blows at her eyes, wishing to make her blind. For this reason she pursues the word and applies it to her eyes as a medicine them, casting away [...] thought of a [...] blindness in [...] afterwards, when that one is again in ignorance, he is completely darkened and is material. Thus the soul [...] a word every hour, to apply it to her eyes as a medicine in order that she may see, and her light may conceal the hostile forces that fight with her, and she may make them blind with her light, and enclose them in her presence, and make them fall down in sleeplessness, and she may act boldly with her strength and with her scepter.

(17) The cause of what is to be warded off, is the absorption of the Seer in things seen.

(12) His parents answered, We know that this is our son, and that he was born blind: but by what means he now seeth, we know not; he is of age; ask him.

(27) And of causes that are occult, some are occult temporarily, being hidden at one time, and at another again seen clearly; and some are occult by nature, and capable of becoming at no time visible. And of those who are so by nature, some are capable of being apprehended; and these some would not call occult, being apprehended by analogy, through the medium of signs, as, for example, the symmetry of the passages of the senses, which are contemplated by reason.

(518) Any one who has common sense will remember that the bewilderments of the eyes are of two kinds, and arise from two causes, either from coming out of the light or from going into the light, which is true of the mind’s eye, quite as much as of the bodily eye; and he who remembers this when he sees any one whose vision is perplexed and weak, will not be too ready to laugh; he will first ask whether that soul of man has come out of the brighter life, and is unable to see because unaccustomed to the dark, or having turned from darkness to the day is dazzled by excess of light. And he will count the one happy in his condition and state of being, and he will pity the other; or, if he have a mind to laugh at the soul which comes from below into the light, there will be more reason in this than in the laugh which greets him who returns from above out of the light into the den. That, he said, is a very just distinction. But then, if I am right, certain professors of education must be wrong when they say that they can put a knowledge into the soul which was not there before, like sight into blind eyes. They undoubtedly say this, he replied. Whereas, our argument shows that the power and capacity of learning exists in the soul already; and that just as the eye was unable to turn from darkness to light without the whole body, so too the instrument of knowledge can only by the movement of the whole soul be turned from the world of becoming into that of being, and learn by degrees to endure the sight of being, and of the brightest and best of being, or

(2) If sight depends upon the linking of the light of vision with the light leading progressively to the illumined object, then, by the very hypothesis, one intervening substance, the light, is indispensable: but if the illuminated body, which is the object of vision, serves as an agent operating certain changes, some such change might very well impinge immediately upon the eye, requiring no medium; this all the more, since as things are the intervening substance, which actually does exist, is in some degree changed at the point of contact with the eye .

Those who have made vision a forth-going act need not postulate an intervening substance- unless, indeed, to provide against the ray from the eye failing on its path- but this is a ray of light and light flies straight. Those who make vision depend upon resistance are obliged to postulate an intervening substance.

The champions of the image, with its transit through a void, are seeking the way of least resistance; but since the entire absence of intervenient gives a still easier path they will not oppose that hypothesis.

So, too, those that explain vision by sympathy must recognize that an intervening substance will be a hindrance as tending to check or block or enfeeble that sympathy; this theory, especially, requires the admission that any intervenient, and particularly one of kindred nature, must blunt the perception by itself absorbing part of the activity. Apply fire to a body continuous through and through, and no doubt the core will be less affected than the surface: but where we are dealing with the sympathetic parts of one living being, there will scarcely be less sensation because of the intervening substance, or, if there should be, the degree of sensation will still be proportionate to the nature of the separate part, with the intervenient acting merely as a certain limitation; this, though, will not be the case where the element introduced is of a kind to overleap the bridge.

But this is saying that the sympathetic quality of the universe depends upon its being one living thing, and that our amenability to experience depends upon our belonging integrally to that unity; would it not follow that continuity is a condition of any perception of a remote object?

The explanation is that continuity and its concomitant, the bridging substance, come into play because a living being must be a continuous thing, but that, none the less, the receiving of impression is not an essentially necessary result of continuity; if it were, everything would receive such impression from everything else, and if thing is affected by thing in various separate orders, there can be no further question of any universal need of intervening substance.

Why it should be especially requisite in the act of seeing would have to be explained: in general, an object passing through the air does not affect it beyond dividing it; when a stone falls, the air simply yields; nor is it reasonable to explain the natural direction of movement by resistance; to do so would bring us to the absurdity that resistance accounts for the upward movement of fire, which on the contrary, overcomes the resistance of the air by its own essentially quick energy. If we are told that the resistance is brought more swiftly into play by the very swiftness of the ascending body, that would be a mere accidental circumstance, not a cause of the upward motion: in trees the upthrust from the root depends on no such external propulsion; we, too, in our movements cleave the air and are in no wise forwarded by its resistance; it simply flows in from behind to fill the void we make.

If the severance of the air by such bodies leaves it unaffected, why must there be any severance before the images of sight can reach us?

And, further, once we reject the theory that these images reach us by way of some outstreaming from the objects seen, there is no reason to think of the air being affected and passing on to us, in a progression of impression, what has been impressed upon itself.

If our perception is to depend upon previous impressions made upon the air, then we have no direct knowledge of the object of vision, but know it only as through an intermediary, in the same way as we are aware of warmth where it is not the distant fire itself that warms us, but the warmed intervening air. That is a matter of contact; but sight is not produced by contact: the application of an object to the eye would not produce sight; what is required is the illumination of the intervening medium; for the air in itself is a dark substance: If it were not for this dark substance there would probably be no reason for the existence of light: the dark intervening matter is a barrier, and vision requires that it be overcome by light. Perhaps also the reason why an object brought close to the eye cannot be seen is that it confronts us with a double obscuration, its own and that of the air.

(2) Now, with reference to the self. — Just that is the formed [Brahma] which is different from breath (frdna) and from the space which is within the sell (atman). This is mortal, this is stationary, this is actual. The essence of this formed, mortal, stationary, actual [Brahma] is the eye, for it is the essence of the actual.

(47) Timaeus: than which no greater boon ever has come or will come, by divine bestowal, unto the race of mortals. This I affirm to be the greatest good of eyesight. As for all the lesser goods, why should we celebrate them? He that is no philosopher when deprived of the sight thereof may utter vain lamentations! But the cause and purpose of that best good, as we must maintain, is this,—that God devised and bestowed upon us vision to the end that we might behold the revolutions of Reason in the Heaven and use them for the revolvings of the reasoning that is within us, these being akin to those,

(25) What is that? The right Eye of Râ in the period of its distress when he giveth it free course, and it is Thoth who lifteth up the net from it

(23) The association of the Seer with things seen is the cause of the realizing of the nature of things seen, and also of the realizing of the nature of the Seer.

(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.

(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

(34) But, indeed, why should I write much of the blindness of the Heathen; are not our doctors, in their crowned ornaments of hoods and cornered caps, as blind as they? Our doctors know indeed that there is a God, who has created all this, but they know not where that God is, nor how he is.

(2) And he adds more clearly: "Him see I not, for round about, a cloud Has settled; for in mortal eyes are small, And mortal pupils - only flesh and bones grow there."

(4) When this self comes to weakness and to confusedness of mind, as it were, then the breaths gather around him. He takes to himself those particles of energy and descends into the heart. When the person in the eye turns away, back [to the sun], then one becomes non-knowing of forms.
