κεκτημένη. See cr. n. Bekker's silence is often untrustworthy, and as he omitted Α and Ξ as well as v in the list of MSS which read κεκτημένην, it is doubtful if even v has the nominative here. κεκτημένην is however very awkward from its position between τὴν προτέραν μιμήσεται and πολεμοῦσα, and the error is so easy and common that I agree with Bekker and others in rejecting the accusative. See § 5. In illustration of what Plato says we may contrast Pausanias for example and Lysander with Brasidas and Callicratidas. The former were σοφοί but far from ἁπλοῖ: the latter θυμοειδεῖς and ἁπλούστεροι.

τοὺς τοιούτους: i.q. τοὺς σοφούς. With μεικτούς cf. 547 A.

ἁπλουστέρους = ‘more singleminded.’ Since they distrust σοφοί because their σοφοί are not ἁπλοῖ, it is natural enough that they should seek ἁπλούστεροι, and find them in θυμοειδεῖς, whose single all-engrossing idea is war (548 A) and φιλονικίαι (548 C). The text would hardly have been suspected if critics had grasped the meaning of ἁπλοῦς (see on I 351 A, II 370 B and IV 434 C). As it is, there is a host of superfluous conjectures: ἀλλοκωτέρους, αὐστηρούς, αὐθαδεστέρους, ποικιλωτέρους (Ast), πολλαπλουστέρους (Stallbaum), ἀγχινουστέρους (Müller), ὑποαμουσοτέρους (Herwerden), ἀμουσοτέρους (Herwerden, Apelt, Richards). It should be remembered that the Spartans prided themselves upon τὸ ἁπλοῦν in the ordinary sense of the term.
