Note 135 — Chapter III · CATEGORIÆ.
Reading edition
Plotinus (Ennead. vi. 1. 80) disapproves greatly the number of disparates ranked under τὸ πὼς ἔχον, which has (he contends) no discoverable unity as a generic term. It is curious to see how he cites the Aristotelian Categories, as if the decuple distinction which they marked out were indefeasible.
Simplikius says that the Stoics distinguished between τὸ πρός τι and τὸ πρός τι πὼς ἔχον; and Trendelenburg, (pp. 228, 229) explains and illustrate this distinction, which, however, appears to be very obscure.
