Perfection of forces is perfection of all things that are actuated and moved by life, in which, however, there is no life. Atmospheres as to their active powers are such forces; the interior and exterior organic substances with man, and with animals of every kind, are such forces; all things in the natural world that are endowed with active powers both immediately and mediately from its sun are such forces.

Perfection of forms and perfection of forces make one, for as the forces are, such are the forms; with the difference only, that forms are substances but forces are their activities; therefore like degrees of perfection belong to both. Forms that are not at the same time forces are also perfect according to degrees.

201. The perfection of life, forces, and forms that increase or decrease according to degrees of breadth, that is, continuous degrees, will not be discussed here, because there is a knowledge of these degrees in the world; but only the perfections of life, forces, and forms that ascend or descend according to degrees of height, that is, discrete degrees; because these degrees are not known in the world. Of the mode in which perfections ascend and descend according to these degrees little can be learned from things visible in the natural world, but this can be seen clearly from things visible in the spiritual world. From things visible in the natural world it is merely found that the more interiorly they are looked into the more do wonders present themselves; as, for instance, in the eyes, ears, tongue; in muscles, heart, lungs, liver, pancreas, kidneys, and other viscera; also, in seeds, fruits and flowers; and in metals, minerals and stones. That wonders increase in all these the more interiorly they are looked into is well known; yet it has become little known thereby that the objects are interiorly more perfect according to degrees of height or discrete degrees. This has been concealed by ignorance of these degrees. But since these degrees stand out conspicuously in the spiritual world (for the whole of that world from highest to lowest is distinctly discreted into these degrees), from that world knowledge of these degrees can be drawn; and afterwards conclusions may be drawn therefrom respecting the perfection of forces and forms that are in similar degrees in the natural world.

202. In the spiritual world there are three heavens, arranged according to degrees of height. In the highest heavens are angels superior in every perfection to the angels in the middle heaven; and in the middle heaven are angels superior in every perfection to the angels in the lowest heaven. The degrees of perfections are such, that angels of the lowest heaven cannot attain to the first threshold of the perfections of the angels of the middle heaven, nor these to the first threshold of the perfections of the angels of the highest heaven. This seems incredible, yet it is a truth. The reason is that they are consociated according to discrete, not according to continuous degrees. I have learned from observation that the difference between the affections and thoughts, and consequently the speech, of the angels of the higher and the lower heavens, is such that they have nothing in common; and that communication takes place only through correspondences, which have existence by immediate influx of the Lord into all the heavens, and by mediate influx through the highest heaven into the lowest. Such being the nature of these differences, they cannot be expressed in natural language, therefore not described; for the thoughts of angels, being spiritual, do not fall into natural ideas. They can be expressed and described only by angels themselves, in their own languages, words, and writings, and not in those that are human. This is why it is said that in the heavens unspeakable things are heard and seen. These differences may be in some measure comprehended when it is known that the thoughts of angels of the highest or third heaven are thoughts of ends; the thoughts of angels of the middle or second heaven thoughts of causes, and the thoughts of angels of the lowest or first heaven thoughts of effects. It must be noted, that it is one thing to think from ends, and another to think about ends; that it is one thing to think from causes, and another to think about causes; and that it is one thing to think from effects, and another to think about effects. Angels of the lower heavens think about causes and about ends, but angels of the higher heavens from causes and from ends; and to think from these is a mark of higher wisdom, but to think about these is the mark of lower wisdom. To think from ends is of wisdom, to think from causes is of intelligence, and to think from effects is of knowledge. From all this it is clear that all perfection ascends and descends along with degrees and according to them.

203. Since the interior things of man, which are of his will and understanding, are like the heavens in respect to degrees (for man, as to the interiors of his mind, is a heaven in least form), their perfections also are like those of the heavens. But these perfections are not apparent to any one so long as he lives in the world, because he is then in the lowest degree; and from the lowest degree the higher degrees cannot be known; but they are known after death, because man then enters into that degree which corresponds to his love and wisdom, for he then becomes an angel, and thinks and speaks things ineffable to his natural man; for there is then an elevation of all things of his mind, not in a single, but in a threefold ratio. Degrees of height are in threefold ratio, but degrees of breadth are in single ratio. But into degrees of height none ascend and are elevated except those who in the world have been in truths, and have applied them to life.

204. It seems as if things prior must be less perfect than things subsequent, that is, things simple than things composite; but things prior out of which things subsequent are formed, that is, things simple out of which things composite are formed, are the more perfect. The reason is that the prior or the simpler are more naked and less covered over with substances and matters devoid of life, and are, as it were, more Divine, consequently nearer to the spiritual sun where the Lord is; for perfection itself is in the Lord, and from Him in that sun which is the first proceeding of His Divine Love and Divine Wisdom, and from that in those things which come immediately after; and thus in order down to things lowest, which are less perfect as they are farther removed. Without such preeminent perfection in things prior and simple, neither man nor any kind of animal could have come into existence from seed, and afterwards continue to exist; nor could the seeds of trees and shrubs vegetate and bear fruit. For the more prior anything prior is, or the more simple anything simple is, the more exempt is it from injury, because it is more perfect.

205. IN SUCCESSIVE ORDER THE FIRST DEGREE MAKES THE HIGHEST, AND THE THIRD THE LOWEST; BUT IN SIMULTANEOUS ORDER THE FIRST DEGREE MAKES THE INNERMOST, AND THE THIRD THE OUTERMOST.

There is successive order and simultaneous order. The successive order of these degrees is from highest to lowest, or from top to bottom. The angelic heavens are in this order; the third heaven there is the highest, the second is the middle, and the first is the lowest; such is their relative situation. In like successive order are the states of love and wisdom with the angels there, also states of heat and light, and of the spiritual atmospheres. In like order are all the perfections of the forms and forces there. When degrees of height, that is, discrete degrees, are in successive order, they may be compared to a column divided into three stories, through which ascent and descent are made. In the upper rooms are things most perfect and most beautiful; in the middle rooms, things less perfect and beautiful; in the lowest, things still less perfect and beautiful. But simultaneous order, which consists of like degrees, has another appearance. In it, the highest things of successive order, which are (as was said above) the most perfect and most beautiful, are in the inmost, the lower things are in the middle, and the lowest in the circumference. They are as if in a solid body composed of these three degrees: in the middle or center are the finest parts, round about this are parts less fine, and in the extremes which constitute the circumference are the parts composed of these and which are therefore grosser. It is like the column mentioned just above subsiding into a plane, the highest part of which forms the innermost of the plane, the middle forms the middle, and the lowest the outermost.

206. As the highest of successive order becomes the innermost of simultaneous order, and the lowest becomes the outermost, so in the Word, "higher" signifies inner, and "lower" signifies outer. "Upwards" and "downwards," and "high" and "deep" have a like meaning.

207. In every outmost there are discrete degrees in simultaneous order. The motor fibers in every muscle, the fibers in every nerve, also the fibers and the little vessels in all viscera and organs, are in such an order. Innermost in these are the most simple things, which are the most perfect; the outermost is a composite of these. There is a like order of these degrees in every seed and in every fruit, also in every metal and stone; their parts, of which the whole is composed, are of such a nature. The innermost, the middle, and the outermost elements of the parts exist in these degrees, for they are successive compositions, that is, bundlings and massings together from simples that are their first substances or matters.
