When you come across a sentence with one or several lacunae, how do you translate it? For instance here: ὀυδὲν δὲ ἀδύνατον τὸ ἀυτὸ κατ’ ἄλλο καὶ ἄλλο … καὶ ὄργανον εἰπεῖν καὶ φυσικὸν καὶ τεχνικὸν.
nothing can be the same as asserted of different things … and to say it is an instrument, natural and artificial.
