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.
