You cannot, I suppose, have a proud and chivalrous spirit if your conduct is mean and paltry; for whatever a man's actions are, such must be his spirit.
ἔστι δ᾿ οὐδέποτ᾿, οἶμαι, μέγα καὶ νεανικὸν φρόνημα λαβεῖν μικρὰ καὶ φαῦλα πράττοντας· ὁποῖ᾿ ἄττα γὰρ ἂν τὰ ἐπιτηδεύματα τῶν ἀνθρώπων ᾖ, τοιοῦτον ἀνάγκη καὶ τὸ φρόνημα ἔχειν.
