ἀφροσύνην τι καλεῖς . See above on 330C

πότερον δὲ ὅταν . Here begins the proof that σωφροσύνη is ἐναντίον ἀφροσύνῃ . (1) τὸ ὀρθῶς and ὠφελίμως πράττειν is σωφρονεῖν , and σωφροσύνη is that by which one σωφρονεῖ ; (2) τὸ μὴ ὀρθῶς πράττειν is ἀφρόνως πράττειν and οὐ σωφρονεῖν : from which it is inferred that ἀφρόνως πράττειν is the opposite of σωφρόνως πράττειν , or (as is worked out at inordinate length) that ἀφροσύνη is the opposite of σωφροσύνη . In equating μὴ ὀρθῶς with ἀφρόνως πράττειν in (2) Socrates again confounds contradictory and contrary: see on 331A

ἢ τοὐναντίον . So Stallbaum, after Heindorf's ἢ τοὐναντίον πράττειν : the MSS. have ἢ εἰ τοὐναντίον ἔπραττον , which is faulty both because it in no way corresponds to the answer σωφρονεῖν and because εἰ with the imperfect is here unsuitable. In ἢ τοὐναντίον it will be observed that Socrates already allows no middle position between σωφρονεῖν and its opposite: see above on l. 3.

φέρε δή . From here to l. 24 Socrates tries to prove that a thing can have but one ἐναντίον . This is true only if we confine ἐναντίον to the meaning of ‘contradictorily opposite’ throughout, e.g. if we are always content merely to assert that the ἐναντίον of καλόν is μὴ καλόν : as soon as we say that its ἐναντίον is αἰσχρόν we have given to the thing two opposites (one of them multiform)—since μὴ καλόν is not αἰσχρόν but may be anything in the whole world except καλόν . This part of the argument is therefore also vitiated by neglecting the difference between contrary and contradictory terms.

ἀναλογισώμεθα : of reckoning up and reflecting as in Rep. I. 330E X. 618C.

ἔμπροσθεν : 332A

τό does not belong to ἕν but to the clause ἓν ἑνὶ μόνον ἐναντίον εἶναι : cf. τὸ εἰ βούλει τοῦτο in 331C ἐκεῖνον refers to ch. XVIII.
