Epictetus, Works, book 3, Περὶ Κυνισμοῦ. 32:

πῶσ ἠμέληται; ἀγνοεῖ τὴν οὐσίαν τοῦ ἀγαθοῦ πρὸσ ἣν πέφυκε καὶ τὴν τοῦ κακοῦ καὶ τί ἴδιον ἔχει καὶ τί ἀλλότριον. καὶ ὅταν τι τῶν ἀλλοτρίων κακῶσ ἔχῃ, λέγει "οὐαί μοι, οἱ γὰρ Ἕλληνεσ κινδυνεύουσι" 3. ταλαίπωρον ἡγεμονικὸν καὶ μόνον ἀτημέλητον καὶ ἀθεράπευτον.
