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.
