Note 122 — Concerning that which is Eternal, for the Purpose of demonstrating the Eternity of the World.
Thomas Taylor translation
Ὄντως in the original, which means indeed literally, truly. But the philosophical reader will please to observe that as it is an adverb derived from the participle ὤν, or being; its full meaning is truly according to being. So that by true life, we must understand life according to the truth of being; and so of the rest.
