Selections from Arcana Cœlestia ~ Emanuel Swedenborg
The eye is the noblest organ of the face, and communicates more immediately with the understanding than do the rest of man's organs of sense. It is also modified by a more subtle atmosphere than the ear, and therefore the sight penetrates to the internal sensory, which is in the brain, by a shorter and more interior way than does the speech which is perceived by the ear. Hence also it is that certain animals, being devoid of understanding, have as it were two subsidiary brains within the orbits of their eyes, for their intellectual depends on their sight.But with man this is not the case, for he enjoys the use of an ample brain, in order that his intellectual may not depend on the sight, but the sight on the intellectual. That the sight of man depends on the intellectual is very evident from the fact that his natural affections portray themselves representatively in the face, but his more interior affections, which pertain to the thought, appear in the eyes, from a certain flame of life and a consequent vibration of light, which flashes out in accordance with the affection in which is the thought; and this a man knows and observes, without being taught by any science, for the reason that his spirit is in society with spirits and angels in the other life, who know this from a plain and clear perception.
Every man as to his spirit is in society with spirits and angelsThere is a correspondence of the sight of the eye with intellectual sight, plainly appears to those who reflect; for the objects of the world, all of which derive something from the light of the sun, enter through the eye, and bestow themselves in the memory, and this evidently under a like visual figure, for whatever is produced therefrom is seen inwardly. This is the source of man's imagination, the ideas of which are called by philosophers material ideas. When these objects appear still more interiorly they present thought, and this also under some visual figure, but more pure, the ideas of which are called immaterial, and also intellectual. That there is an interior light, in which there is life, and consequently intelligence and wisdom, and that this light illumines the interior sight, and meets the things which have entered in through the external sight, is very evident; and also that the interior light operates according to the disposition of the things present there from the light of the world. The things that enter through the hearing are also inwardly turned into forms like those of the visual images that come from the light of the world.
As the sight of the eye corresponds to intellectual sight, it also corresponds to truths, for all things that are of the understanding bear relation to truth, and likewise to good, in this way - that a man may not only know what is good, but also be affected by it. Moreover all things of the external sight also bear relation to truth and to good, because they bear relation to the symmetries of objects, consequently to their beauties and the derivative charms. A clear-sighted observer can see that each and all things in nature bear relation to truth and to good, and thereby he can also know that universal nature is a theater representative of the Lord's kingdom.
