Quantity and Quality Fail to Appear Among the Primary Genera

The distinction to be established does not proceed from simpleness or compositeness but of simpleness and what completes being. Quantity is not a primary genus because it is posterior to being. Why does quality also fail to appear among the primary genera? Because quality also is posterior to them. It does indeed follow after being. The four other categories do not together form quality. They do not form a certain being. Movement evidently does not introduce any quality in essence. That number is to be posited among stable things while dimension belongs among those in movement. But as said above all this will be treated of later.
