Psalm 94:9

Verse 9. The eye. As illustrating the wisdom displayed in the eye we have selected the following. "Our physical good demands that we should have the power of comprehending the world in all the respects in which it is possible for matter or its forces to affect our bodies." The senses completely meet this want... We are too apt to confine ourselves to the mere mechanism of the eye or ear, without considering how the senses supplement each other, and without considering the provision made in the world that it may be a fit place for the exercise of the senses. The eye would be useless without all the properties of light; the ear would have no power in a world without an atmosphere. Sight enables us to avoid danger, and seek distant needful objects. What a vast length of time and wearisome labour would it require for a blind man to learn what one glance of the eye may give to one blessed with sight. A race of blind men could not exist on this globe.

The sense of sight alone, as a means of adapting us to the world, would strike us as wonderful in its results, and worthy of the conception of the highest intelligence in adapting means to ends, if we knew nothing of the adjustments by which sight is secured. We can conceive of the power of sight as direct perception, without the aid of light, or of a special organ corresponding to the eye. But constituted as we are, we see only through the agency of light; and we perceive light only by a special organ; and objects only in consequence of a peculiar structure of that organ. Of all these relationships of light to objects, and of light to the eye, and of the parts of the eye to each other, not one of them is a necessary condition of matter. The arrangement of so many things by which this wonderful power of perceiving distant objects is secured, is the only one that will secure the end desired, out of an endless number of arrangements that can be conceived of... Whoever contrived the organ through which we are to perceive, understood perfectly all the properties of light, and the wants of the being that was to use it. The eye of man, though limited in its power to a certain range, gives all that the common wants of life demand. And if man needs greater range of vision, he has but to study the eye itself, and fashion instruments to increase its power; as he is able when the proper time has come in his civilization, to increase by science and art the efficacy of nearly all his physical powers. For the ordinary purposes of life, neither telescopic nor microscopic adjustment of the eye is needful.

But the eye has not only the power of vision so necessary to man, but it is an instrument of power, an instrument made up of distinct parts, of solids and liquids, of transparent and opaque tissues, of curtains, and lenses, and screens. Its mechanism can be accurately examined and the use of each part as perfectly understood as any of the works of man. We examine every part of it as we would a microscope. We have first the solid case which is to hold all the machinery, and upon which are to be fastened the cords and pulleys of its skilful mounting. This covering, opaque, white, and glistening, like silver on the back and sides of the eye, in front, where the light must enter, suddenly becomes transparent as the clearest crystal. Within this is a second coating that coming to the front changes just as suddenly into an opaque screen, through the tissues of which no ray of light can pass. That screen is self adjusting, with a network that no art of man ever equalled. Whether expanding or contracting, its opening in the centre always remains a perfect circle, adapted in size to the intensity of the light. How much light shall enter the eye it determines without aid from us. Next there must be connection with the brain, the seat of the being for whom the provision is made. These two coatings are pierced upon the back part of the eye, and a thread draw out from the brain is passed through this opening and spread out within the eye as a delicate screen upon which all impressions are to be made. To fill the larger portion of the cavity, there is packed into it a clear jelly, and imbedded in this a lens, fashioned with a skill that no artist can equal, to refract the light and throw the image on the perceptive screen. In front of this lens is another humour, not like jelly as the other, because in this, that delicate fringe the iris, is to float, and nothing but a watery fluid will answer its purpose. Here then we have a great variety of materials all brought together, of the exact quality and in the quantity needed, placed in the exact position which they ought to occupy, so perfectly adjusted that the most that man can do is to imitate the eye without ever hoping to equal it.

Nor is the curious structure of the eye itself all that is worthy of our attention. The instrument when finished must be mounted for use. A cavity is formed in solid bone, with grooves and perforations for all the required machinery. The eye, when placed, is packed with soft elastic cushions and fastened by strings and pulleys to give it variety and rapidity of motion. Its outer case is to cover it when not in use, and protect it when in danger. The delicate fringe upon its border never needs clipping; and set like a well arranged defence, its points all gracefully turned back, that no ray of light may be obstructed. Above the protecting brow is another defence to turn aside the acrid fluids from the forehead, while near the eye is placed a gland that bathes the whole organ with a clear soothing fluid, to prevent all friction and keep its outward lens free from dust, and polished for constant use. When we consider all this, the perfect adaptation of the eye to our wants, the arrangement of every part of its structure on strict mechanical and optical principles, and all the provisions for its protection, we pronounce the instrument perfect, the work of a Being like man, but raised immeasurably above the most skilful human workman. What shall we say when we learn that this instrument was prepared in long anticipation of its use; that there is a machinery within it to keep it in constant repair; that the Maker not only adjusted the materials, but that he was the chemist who formed all these substances from the dust of the earth? We may be told that the architect found this dust ready at hand, existing from all eternity. We may not be able to prove the contrary, nor do we need to do so for this argument. It is enough for our present purpose to know that the eyes with which we now see, these wonderfully complex and perfect instruments, were not long since common earth, dust upon which we perchance have trod.

We can understand the mechanism of the eye, we can comprehend the wisdom that devised it; but the preparation of materials, and the adjustment of parts, speak of a power and skill to which man can never hope to attain. When he sees his most cunning workmanship surpassed both in plan and execution, shall he fail to recognise design? "Shall we fail to recognise a builder when we contemplate such a work?" P. A. Chadbourne, in "Lectures on Natural Theology"; or, Nature and the Bible from the same Author. New York, 1867.

Verse 9. Shall he not see? A god or a saint that should really cast the glance of a pure eye into the conscience of the worshipper would not long be held in repute. The grass would grow again around that idol's shrine. A seeing god would not do: the idolater wants a blind god. The first cause of idolatry is a desire in an impure heart to escape from the look of the living God, and none but a dead image would serve the turn. William Arnot.

Verse 9. He who made the sun itself, and causes it to revolve, being a small portion of his works, if compared with the whole, is he unable to perceive all things? Epictus.

Verse 9. That is wise counsel of the Rabbins, that the three best safeguards against falling into sin are to remember, first, that there is an ear which hears everything; secondly, that there is an eye which sees everything; thirdly, that there is a hand which writes everything in the Book of Knowledge, which shall be opened at the Judgment. J. M. Neale.

Verse 9-10. It was no limited power that could make this eye to see, this ear to hear, this heart to understand; and, if that eye which he hath given us, can see all things that are within our prospect, and that ear, that he hath planted, can hear all sounds that are within our compass, and that heart, that he hath given us, can know all matters within the reach of our comprehension; how much more shall the sight, and hearing, and knowledge of that Infinite Spirit, which can admit of no bounds, extend to all the actions and events of all the creatures, that lie open before him that made them! Joseph Hall.

Verse 10. He that teacheth man knowledge. The question posts midway (for the words in Italics are not Scripture), the point of application being too obvious to need mention. "He that teacheth man all his knowledge." (Fill out the rest yourselves; think, What then?) Henry Cowles.
