FIVE PHYSICAL CATEGORIES.
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.
