201. The perfections of life, forces and forms increasing or decreasing according to degrees of breadth, that is, continuous degrees, will not be discussed here because these degrees are known in the world, but perfections of life, forces and forms ascending or descending according to degrees of height or discrete degrees will be discussed, for those degrees are not known in the world. But how perfections ascend and descend according to those degrees can he little understood from things visible in the natural world, but clearly from things visible in the spiritual world. From things visible in the natural world, it is only discovered that the more they are looked into, the more do wonders appear, as, for example, in the eyes, ears, tongue, in muscles, heart, lung, liver, pancreas, kidneys and other viscera; also in seeds, fruits and flowers; and again in metals, minerals and stones. It is well known that in all these, wonders appear the more they are looked into. But yet from these things it has been little suspected that these objects are interiorly more perfect according to degrees of height or discrete degrees. Ignorance of those degrees has concealed the fact. But because the same degrees stand out conspicuously in the spiritual world, for the whole of that world, from highest to lowest, is distinctly discreted into these degrees, therefore from that world knowledge of these degrees can be drawn. Then conclusions can be drawn therefrom about perfection of forces and forms which are in similar degrees in the natural world.
