Reading edition
Xenoph. Mem. iii. 9, 4-5. σοφίαν δὲ καὶ σωφροσύνην οὐ διώριζεν, &c.
Compare the discussion of σωφροσύνη, iv. 5, 9-11, where Sokrates enforces the practice of it on the ground that it ensured to a man both more pleasures and greater pleasures, of which he would deprive himself if he were foolish enough to be intemperate.
