I will select the example of weaving, or, more precisely, weaving of wool.
In the first place, all possessions are either productive or preventive; of
the preventive sort are spells and antidotes, divine and human, and also
defences, and defences are either arms or screens, and screens are veils
and also shields against heat and cold, and shields against heat and cold
are shelters and coverings, and coverings are blankets or garments, and
garments are in one piece or have many parts; and of these latter, some are
stitched and others are fastened, and of these again some are made of
fibres of plants and some of hair, and of these some are cemented with
water and earth, and some are fastened with their own material; the latter
are called clothes, and are made by the art of clothing, from which the art
of weaving differs only in name, as the political differs from the royal
science. Thus we have drawn several distinctions, but as yet have not
distinguished the weaving of garments from the kindred and co-operative
arts. For the first process to which the material is subjected is the
opposite of weaving--I mean carding. And the art of carding, and the whole
art of the fuller and the mender, are concerned with the treatment and
production of clothes, as well as the art of weaving.
