190. All phenomena that occur in the world which exhibit a threefold dimension, or which are what we call composites, consist of degrees of height or discrete degrees. But let examples serve to illustrate. We know from visual observation that every muscle in the human body consists of minute fibers, that these are composed into fascicles to form larger fibers called motor fibers, and that bundles of these constitute the composite which we call a muscle. It is the same with nerves. In them minute fibers are woven together to form larger ones, which look like threads. Aggregations of these are woven together to form the nerve.  The same is the case in all the other weavings, bundlings and aggregations which make up the organs and viscera. For these are compositions of fibers and vessels variously formed in accordance with the same degrees. The same is also the case in each and all constituents of the plant kingdom, and in each and all constituents of the mineral kingdom. In pieces of wood we find combinations of fibers woven together in a threefold arrangement. In metals and stones we find aggregations of their constituents also in a threefold arrangement. This makes apparent the nature of discrete degrees, namely, that from one arises another, and through this a third, which is called the composite; and that each degree is distinct from any other.
