22. φθήσεται ἄρα ἐπʼ εὐθείας p. 314, ἐπειδὴ τὸ Α αὐτὸ οὐχ ὁρᾶται ἐν τῷ ἐσόπτρῳ, ἀλλὰ τὸ εἴδωλον αὐτοῦ, ὃ ἔσω που τῇ νοήσει τοῦ ἐσόπτρου ὁρώμενον κατὰ τὴν σύμπτωσιν ὁρᾶται κατὰ τὸ Ε, ἐπειδή, εἰ ἐπʼ εὐθείας εἰσὶν αἱ ὁράσεις, τὸ Β ἔσω που τοῦ ἐνόπτρου ὄψεται, εἰ δὲ ἔσω, ἀνάγκη ἀπὸ τοῦ ὁρωμένου ἀχθεῖσαν εἰς σύμπτωσιν αὐτῆς φθάσαι, ὡς ἔσται τόπος τοῦ ἔσω δοκοῦντος ἐν τῷ ἐνόπτρῳ φαίνεσθαι.
