BODIES MAY BE CLASSIFIED NOT ONLY BY FORMS; BUT BY QUALITIES; ETC.
10. Bodies may also be distinguished by heat or dryness, wetness or cold, or in any other desired manner, by taking two qualities simultaneously, then considering these things as a composition and mixture, and ceasing at the combination thereof. Or, bodies may be divided in terrestrial bodies, that dwell on the earth, or distribute them according to their forms, and the differences of animals; by classifying not the animals themselves, but their bodies, which are their instruments,[378] as it were. It is proper to establish a classification according to the forms, as it is equally reasonable to classify bodies according to their qualities, such as heat, cold, and so forth. If it be objected that bodies are constituted rather by their qualities, it may be answered that they are just as much classified by their blends, their colors, and their figures. When analyzing sense-being, it is not unreasonable to classify it according to the differences that appear to the senses.[379] This ("being") does not possess absolute (Essence); it is the totality of the matter and qualities which constitutes the sense-being, since we have said that its hypostatic existence consists in the union of the things perceived by the senses, and that it is according to the testimony of their senses that men believe in the existence of things.
