Plato, Laws 817b

ἐμοὶ μὲν γὰρ δοκεῖ τάδε· ὦ ἄριστοι, φάναι, τῶν ξένων, ἡμεῖς ἐσμὲν τραγῳδίας αὐτοὶ ποιηταὶ κατὰ δύναμιν ὅτι καλλίστης ἅμα καὶ ἀρίστης· πᾶσα οὖν ἡμῖν ἡ πολιτεία συνέστηκε μίμησις τοῦ καλλίστου καὶ ἀρίστου βίου, ὃ δή φαμεν ἡμεῖς γε ὄντως εἶναι τραγῳδίαν τὴν ἀληθεστάτην. ποιηταὶ μὲν οὖν ὑμεῖς, ποιηταὶ δὲ καὶ ἡμεῖς ἐσμὲν τῶν αὐτῶν, ὑμῖν ἀντίτεχνοί τε καὶ ἀνταγωνισταὶ τοῦ καλλίστου δράματος, ὃ δὴ νόμος ἀληθὴς μόνος ἀποτελεῖν πέφυκεν, ὡς

we ourselves, to the best of our ability, are the authors of a tragedy at once superlatively fair and good; at least, all our polity is framed as a representation of the fairest and best life, which is in reality, as we assert, the truest tragedy. Thus we are composers of the same things as yourselves, rivals of yours as artists and actors of the fairest drama, which, as our hope is, true law, and it alone, is by nature competent to complete.
