6. ἀλλήλων καὶ τοῦ ὅλου: so the MSS. and Heindorf (who suggests ἀλλήλων τε καὶ τοῦ ὅλου): recent editors mostly omit either ἀλλήλων or τὰ ἕτερα τῶν ἑτέρων. τὰ ἕτερα τῶν ἑτέρων should be taken quite generally, τῶν ἑτέρων (and thus, by implication, τὰ ἕτερα) having its meaning defined by the clause ἀλλήλων καὶ τοῦ ὅλου. τὰ ἕτερα τῶν ἑτέρων could be dropped without injury to the sense, but hardly ἀλλήλων: without ἀλλήλων Plato would have written οὐδὲν διαφέρει τὸ ἕτερον τοῦ ἑτέρου καὶ τοῦ ὅλου: cf. 330Aἆρ᾽ οὖν οὕτω καὶ τὰ τῆς ἀρετῆς μόρια οὐκ ἔστιν τὸ ἕτερον οἷον τὸ ἕτερον (not τὰ ἕτερα οἷα τὰ ἕτερα); and so 330E 331A 331D 349B 359A
