Aretēs

Τίνι μὲν γὰρ δεῖ πλείονος φρονήσεως ἢ τῷ βουλευομένῳ περὶ τῶν μεγίστων; τίνι δὲ ἀκριβεστέρας δικαιοσύνης ἢ τῷ μείζονι τῶν νόμων; τίνι δὲ σωφροσύνης ἐγκρατεστέρας ἢ ὅτῳ πάντα ἔξεστι; τίνι δὲ ἀνδρείας ἰσχυροτέρας ἢ ὑφ’ οὗ πάντα σῴζεται; τίνα δὲ μᾶλλον εὐφραίνει τὰ ἔργα τῆς ἀρετῆς ἢ τὸν σύμπαντας ἀνθρώπους θεατὰς καὶ μάρτυρας ἔχοντα τῆς αὑτοῦ ψυχῆς; ὥστε μήποτε πράξαντι μηδὲν οἷόν τε λαθεῖν, οὐ μᾶλλον ἢ τῷ ἡλίῳ πορεύεσθαι διὰ σκότους· πάντα γὰρ τἄλλα ἀναφαίνων πρῶτον ἑαυτὸν ἐπιδείκνυσι.
(Dio Chrysostom, Or. 3.10-11)

Who, in fact, must exercise greater wisdom than he who is concerned with the weightiest matters; who, a keener sense of justice than he who is above the law; who, a more rigorous self-control than he to whom all things are permissible; who, a stouter courage than he upon whom the safety of everything depends? And who takes greater delight in the works of virtue than he who has all men as spectators and witnesses of his own soul? — so that nothing he may do can ever be hidden any more than the sun can run its course in darkness; for, in bringing all other things to light, it reveals itself first.
