Plato, Laws 694c

πῇ δὴ οὖν ποτε ἀπώλετο ἐπὶ Καμβύσου καὶ πάλιν ἐπὶ Δαρείου σχεδὸν ἐσώθη; βούλεσθε οἷον μαντείᾳ διανοηθέντες χρώμεθα; φέρει γοῦν ἡμῖν σκέψιν τοῦτο ἐφʼ ὅπερ ὡρμήκαμεν. μαντεύομαι δὴ νῦν περί γε Κύρου, τὰ μὲν ἄλλʼ αὐτὸν στρατηγόν τε ἀγαθὸν εἶναι καὶ φιλόπολιν, παιδείας δὲ ὀρθῆς οὐχ ἧφθαι τὸ παράπαν, οἰκονομίᾳ τε οὐδὲν τὸν νοῦν προσεσχηκέναι. πῶς δὴ τὸ τοιοῦτον φῶμεν;

How came it, then, that they were ruined in Cambyses’ reign, and nearly restored again under Darius? Shall I use a kind of divination to picture this? Yes that certainly will help us to gain a view of the object of our search. What I now divine regarding Cyrus is this,—that, although otherwise a good and patriotic commander, he was entirely without a right education, and had paid no attention to household management. What makes us say this?
