ἀνάγειν πρῶτον ἐπ᾽ ἐκεῖνα ἐν οἷς ταὐτὰ ταῦτα ὀρθῶς ἐδόξαζον, ἀναγαγόντας δὲ τιθέναι παρὰ τὰ μήπω (278b) γιγνωσκόμενα, καὶ παραβάλλοντας ἐνδεικνύναι τὴν αὐτὴν ὁμοιότητα καὶ φύσιν ἐν ἀμφοτέραις οὖσαν ταῖς συμπλοκαῖς, μέχριπερ ἂν πᾶσι τοῖς ἀγνοουμένοις τὰ δοξαζόμενα ἀληθῶς παρατιθέμενα δειχθῇ, δειχθέντα δέ, παραδείγματα οὕτω γιγνόμενα, ποιήσῃ τῶν στοιχείων ἕκαστον πάντων ἐν πάσαις ταῖς συλλαβαῖς τὸ μὲν ἕτερον ὡς τῶν ἄλλων ἕτερον ὄν, τὸ (278c) δὲ ταὐτὸν ὡς ταὐτὸν ἀεὶ κατὰ ταὐτὰ ἑαυτῷ προσαγορεύεσθαι.
eng tr. Jowett 1817-1893STRANGER:
To refer them first of all to cases in which they judge correctly about the letters in question, and then to compare these with the cases in which they do not as yet know, and to show them that the letters are the same, and have the same character in both combinations, until all cases in which they are right have been placed side by side with all cases in which they are wrong. In this way they have examples, and are made to learn that each letter in every combination is always the same and not another, and is always called by the same name.
