Aristotle, Eudemian Ethics, Book 3 81:

λυπεῖσθαι ταύτην τὴν λύπην ἣν καλοῦμεν θυμόν. ἐπεὶ δ’ ὥσπερ καὶ ἐπὶ τῶν ἄλλων εἴπομεν, καὶ ἐνταῦθ’ ἐστὶν ὑπερβολὴ καὶ ἔλλειψισ ὁ μὲν γὰρ χαλεπὸσ τοιοῦτοσ ἐστίν, ὁ καὶ θᾶττον καὶ μᾶλλον πάσχων καὶ πλείω χρόνον καὶ ὅτ’ οὐ δεῖ καὶ ὁποίοισ οὐ δεῖ καὶ ἐπὶ πολλοῖσ, ὁ δ’ ἀνδραποδώδησ τοὐναντίον, δῆλον ὅτι ἔστι τισ καὶ ὁ μέσοσ τῆσ ἀνισότητοσ.
