Note 160 — Chapter XIII · DAILY DUTIES.
Reading edition
The emphasis occasionally laid on εὐφυΐα (bona indoles) reflects aristocratic and Platonic influences, see Pearson, pp. 205, 206; ‘those who have a good natural disposition (οἱ εὐφυεῖς), even if you try to turn them aside, cling still more to reason’ Epict. Disc. iii 6, 9.
