16 f.
τὸ ἀδικεῖν . . . εἶναι: is cited as an example of rather uncommon use of the indir. disc. inf. after εἶπον (GMT. 753, 3), but the clause is to be looked at rather as the object of εἶπον in the sense of “declare.”
καὶ ἐξηλέγχθην ὑπὸ σοῦ: of course the addition of Socrates after Polus' reply throws a quite different coloring over this sentence. Polus' self-assurance is apparent in ϝαὶ μὰ Δία, his positiveness in ἀληθῆ γε οἰόμενος. ἴσως shows no uncertainty, but is only the conscious under-statement which is common in English. See on 480 a.
