Passages
From the texts
The same quality, moreover, is said to subsist in a thing in varying degrees at different times.
— Aristotle, Categories
The primary quality is the differentia of the essence, and of this the quality in numbers is a part; for it is a differentia of essences, but either not of things that move or not of them qua moving.
— Aristotle, Metaphysics
