190. All things which exist in the world, about which a threefold dimension is predicated, or which are called composite, consist of degrees of height or discrete degrees. But examples will make this clear. It is known from ocular experience that every muscle in the human body consists of minute fibres and that these, gathered together into little bundles, form larger fibres, called motor fibres and that from groups of these exists the composite thing called a muscle. It is the same with nerves. In these from most minute fibres knitted together are formed greater ones which appear as filaments. From these massed together is woven the nerve. It is the same in the rest of the combinations, bundles and groupings out of which organs and viscera are made up; for these are composites out of fibres and vessels variously put together through similar degrees. It is also the same with each and every thing of the vegetable kingdom, and of the mineral kingdom. In woods there are combinations of filaments in threefold order. In metals and stones there are massed together parts also in threefold order. From these examples it is clear what discrete degrees are, namely, that one thing exists from another, and from this other, a third which is called a composite; and that each degree is discreted from the other.
