Note 8 — Chapter XXXVII · REPUBLIC — REMARKS ON THE PLATONIC COMMONWEALTH.
Reading edition
See Charmidês, pp. 161-162. Heindorf observes in his note on this passage:— “A sophistis ergo vulgata hæc σωφροσύνης definitio: ad justitiam quoque ab iisdem ut videtur, translata. Republ. iv. p. 433 (the passage cited in note preceding). Quo pertinent illa Ciceronis, De Officiis, i. 9, 2. Item ad prudentiam, Aristot. Eth. Nicom. vi. 8, Philosopho vero hoc tribuit Sokrates, Gorgias, p. 526).”
The definition given in the Charmidês appears plainly ascribed to Kritias as its author (p. 162 D). The affirmation that it was “a sophistis vulgata,” and afterwards transferred by these same to Justice, is made without any authority produced; and is expressed in the language usual with the Platonic commentators, who treat the Sophists as a philosophical sect or school.
