Oswald J. (Oswald Joseph) Reichel translation
Sext. Math. xi. 169: Ἐπίκουρος ἔλεγε τὴν φιλοσοφίαν ἐνέργειαν εἶναι λόγοις καὶ διαλογισμοῖς τὸν εὐδαίμονα βίον περιποιοῦσαν. Conf. Epic. in Diog. 122: The demand to study philosophy in youth, as well as in age, is supported on the ground that it is never too early nor too late to be happy. ↑
