I want to know how to say, "Double negation affirms by accident" or "Double negation affirms accidentally." Would it be duplex negatio affirmat per accidens? This is in reference to the idea from logic and grammar that double negation affirms and from the idea in metaphysics that properties either are essential or accidental.
I'm coming to this in specific reference to the following excerpt from Arist. Int. 14.23b15-17: “Si ergo quod bonum et bonum et non malum est, et hoc quidem secundum se, illud vero secundum accidens (accidit enim ei malum non esse).” In the 'original' Classical Attic this was: "εἰ οὖν τὸ ἀγαθὸν καὶ ἀγαθὸν καὶ οὐ κακόν ἐστιν, καὶ τὸ μὲν καθ’ αὑτὸ τὸ δὲ κατὰ συμβεβηκός (συμβέβηκε γὰρ αὐτῷ οὐ κακῷ εἶναι)."
