Enneads VI.1: Of the Ten Aristotelian and Four Stoic Categories
4. Relation; the Stoics Confuse the New with the Anterior
31If the Stoics did not, along with the other discussed categories, reduce relation to a common kind, there might be good grounds to examine whether they attributed substantial (or, hypostatic) reality to these manners of “being”; for often, they do not attribute to them any. But what is to be said of their confusing things new and anterior in one same classification? This is evidently an absurdity; for surely one and two must exist before the half or the double.
As to the philosophers (Plato, for instance), who have taught other opinions about essences and their principles, considered as finite or infinite, corporeal or incorporeal, or both simultaneously corporeal or incorporeal, we will examine each of these opinions separately, considering also the historic objections of the ancient (philosophers).
