ἔστω: be it so; an attempt to make the unavoidable concession without assent.
ὅτι ἀδικοῦσιν: (see on b, 1. 53, above, ὅτι ἀδικεῖ) is here emphatically repeated, as is afterwards ἀδικοῦντες. Thus the attention is held to the question, with reference to the σωφρονεῖν ἀδικοῦντα, whether a εὖ φρονεῖν and εὖ βουλεύεσθαι can be thought of in the particular relation to the ἀδικεῖν, and not in relation to something else with which the ἀδικεῖν might accidentally be associated. By means of the proof that this is inconceivable, Socrates aims to reach the demonstration that <*>ωφροσύνη and δικαιοσύνη are one.
