185. Each and all things that have existence in the spiritual world and in the natural world, have conjoint existence from discrete degrees and from continuous degrees together, that is, from degrees of height and from degrees of breadth. The dimension which consists of discrete degrees is called height, and the dimension that consists of continuous degrees is called breadth; their position relatively to the sight of the eye does not alter the designation. Without a knowledge of these degrees nothing can be known of how the three heavens differ from each other; nor can anything be known of the differences of love and wisdom of the angels there; nor of the differences of heat and light in which they are; nor of the differences of atmospheres which environ and contain these. Nor without a knowledge of these degrees can anything be known of the differences among the interior powers of the minds of men, thus nothing of their state as regards reformation and regeneration; nor anything of the differences among the exterior powers of the bodies both of angels and men; and nothing whatever can be known of the distinction between spiritual and natural, thus nothing of correspondence. Nor, indeed, can anything be known of any difference between the life of men and that of beasts, or between the more perfect and the less perfect animals; neither of the differences among the forms of the vegetable kingdom, nor among the matters of the mineral kingdom. From which it can be seen that they who are ignorant of these degrees are unable to see causes from anything of judgment; they see only effects, and from these judge of causes, which is done for the most part by an induction that is continuous with effects. But causes produce effects not continuously but discretely; for cause is one thing, and effect is another. The difference between the two is like the difference between prior and subsequent, or between that which forms and that which is formed.
186. That it may be still better comprehended what discrete degrees are, what their nature is, and how they differ from continuous degrees, the angelic heavens may serve as an example. There are three heavens, and these are separated by degrees of height; therefore the heavens are one below another, nor do they communicate with each other except by influx, which proceeds from the Lord through the heavens in their order to the lowest; and not contrariwise. Each heaven by itself, however, is divided not by degrees of height but by degrees of breadth. Those who are in the middle, that is, at the center, are in the light of wisdom; but those who are around about, even to the boundaries, are in the shade of wisdom. Thus wisdom grows less and less even to ignorance, as light decreases to shade, which takes place continuously. It is the same with men. The interiors belonging to their minds are separated into as many degrees as the angelic heavens; and these degrees are one above another; therefore the interiors of men which belong to their minds are separated by discrete degrees, that is, degrees of height. Consequently a man may be in the lowest degree, then in a higher, and also in the highest degree, according to the degree of his wisdom; moreover, when he is in the lowest degree only, the higher degree is shut, - but is opened as he receives wisdom from the Lord. There are also in a man, as in heaven, continuous degrees, that is degrees of breadth. A man is like the heavens because as regards the interiors of his mind, he is a heaven in least form, in the measure in which he is in love and wisdom from the Lord. That man as regards the interiors of his mind is a heaven in least form may be seen in the work Heaven and Hell (n. 51-58.)
187. From all this it can be seen, that one who knows nothing about discrete degrees, that is, degrees of height, can know nothing about the state of man as regards his reformation and regeneration, which are effected through the reception of love and wisdom of the Lord, and then through the opening of the interior degrees of his mind in their order. Nor can he know anything about influx from the Lord through the heavens nor anything about the order into which he was created. For if anyone thinks about these, not from discrete degrees or degrees of height but from continuous degrees or degrees of breadth, he is not able to perceive anything about them from causes, but only from effects; and to see from effects only is to see from fallacies, from which come errors, one after another; and these may be so multiplied by inductions that at length enormous falsities are called truths.
188. I am not aware that anything has been known hitherto about discrete degrees or degrees of height, only continuous degrees or degrees of breadth have been known; yet nothing of the real truth about cause can become known without a knowledge of degrees of both kinds. These degrees therefore shall be treated of throughout this Part; for it is the object of this little work to uncover causes, that effects may-be seen from them, and thus the darkness may be dispelled in which the man of the church is in respect to God and the Lord, and in respect to Divine things in general which are called spiritual things. This I may mention, that the angels are in grief for the darkness on the earth; saying that they see light hardly anywhere, and that men eagerly lay hold of fallacies and confirm them, thereby multiplying falsities upon falsities; and to confirm fallacies men search out, by means of reasonings from falsities and from truths falsified, such things as cannot be controverted, owing to the darkness in respect to causes and the ignorance respecting truths. The angels lament especially over confirmations respecting faith separate from charity and justification thereby; also over men's ideas about God, angels and spirits, and their ignorance of what love and wisdom are.
189. DEGREES OF HEIGHT ARE HOMOGENEOUS, AND ONE IS FROM THE OTHER IN SUCCESSION LIKE END, CAUSE, AND EFFECT.
As degrees of breadth, that is continuous degrees, are like gradations from light to shade, from heat to cold, from hard to soft, from dense to rare, from thick to thin, and so forth; and as these degrees are known from sensuous and ocular experience, while degrees of height, or discrete degrees, are not, the latter kind shall be treated of especially in this Part; for without a knowledge of these degrees, causes cannot be seen. It is known indeed that end, cause, and effect follow in order, like prior, subsequent, and final; also that the end begets the cause, and, through the cause, the effect, that the end may have form; also about these many other things are known; and yet to know these things, and not to see them in their applications to existing things is simply to know abstractions, which remain in the memory only so long as the mind is in analytical ideas from metaphysical thought. From this it is that although end, cause, and effect advance according to discrete degrees, little if anything is known in the world about these degrees. For a mere knowledge of abstractions is like an airy something which flies away; but when abstractions are applied to such things as are in the world, they become like what is seen with the eyes on earth, and remains in the memory.
190. All things which have existence in the world, of which threefold dimension is predicated, that is, which are called compounds, consist of degrees of height, that is, discrete degrees; as examples will make clear. It is known from ocular experience, that every muscle in the human body consists of minute fibers, and these put together into little bundles form larger fibers, called motor fibers, and groups of these form the compound called a muscle. It is the same with nerves; in these from minute fibers larger fibers are compacted, which appear as filaments, and these grouped together compose the nerve. The same is true of the rest of the combinations, bundlings and groupings out of which the organs and viscera are made up; for these are compositions of fibers and vessels variously put together according to like degrees. It is the same also with each and every thing of the vegetable and mineral kingdoms. In woods there are combinations of filaments in threefold order. In metals and stones there are groupings of parts, also in threefold order. From all this the nature of discrete degrees can be seen, namely, that one is from the other, and through the second there is a third which is called the composite; and that each degree is discreted from the others.
191. From these examples a conclusion may be formed respecting those things that are not visible to the eye, for with those it is the same; for example, with the organic substances which are the receptacles and abodes of thoughts and affections in the brains; with atmospheres; with heat and light; and with love and wisdom. For atmospheres are receptacles of heat and light; and heat and light are receptacles of love and wisdom; consequently, as there are degrees of atmospheres, there are also like degrees of heat and light, and of love and wisdom; for the same principle applies to the latter as to the former.
192. That these degrees are homogeneous, that is, of the same character and nature, appears from what has just been said. The motor fibers of muscles, least, larger, and largest, are homogeneous. Woody filaments, from the least to the composite formed of these, are homogeneous. So likewise are parts of stones and metals of every kind. The organic substances which are receptacles and abodes of thoughts and affections, from the most simple to their general aggregate which is the brain, are homogeneous. The atmospheres, from pure ether to air, are homogeneous. The degrees of heat and light in series, following the degrees of atmospheres, are homogeneous, therefore the degrees of love and wisdom are also homogeneous. Things which are not of the same character and nature are heterogeneous, and do not harmonize with things homogeneous; thus they cannot form discrete degrees with them, but only with their own, which are of the same character and nature and with which they are homogeneous.
193. That these things in their order are like ends, causes, and effects, is evident; for the first, which is the least, effectuates its cause by means of the middle, and its effect by means of the last.
