We decide, therefore, that the three first things (matter, form, and
their combination) contribute to the formation of a single genus,
which, by a figure of speech, we call ("corporeal) Being," a genus
which is common to them, and whose name applies to all three. Then
come the other genera; such as relation, quantity and quality; the
(relation of) being "contained in place," and "in time"; movement; and
place and time. But as the category of "time" and "place" would render
superfluous that of "being in place" and of "being in time,"[353] we
should limit ourselves to the recognition of five genera, of which the
first ("being") comprises matter, form and the combination.[354] If,
however, we should not count matter, form and combination as a single
genus, our analysis will assume the following shape: matter, form,
combination, relation, quantity, quality, and movement. Otherwise, the
latter three might be subsumed under relation, which possesses more
extension than they.
