Plato, Laws 885d

περὶ νόμων, πρὶν ἀπειλεῖν ἡμῖν σκληρῶς, ὑμᾶς πρότερον ἐπιχειρεῖν πείθειν καὶ διδάσκειν ὡς εἰσὶ θεοί, τεκμήρια λέγοντες ἱκανά, καὶ ὅτι βελτίους ἢ παρὰ τὸ δίκαιον ὑπό τινων δώρων παρατρέπεσθαι κηλούμενοι. νῦν μὲν γὰρ ταῦτα ἀκούοντές τε καὶ τοιαῦθʼ ἕτερα τῶν λεγομένων ἀρίστων εἶναι ποιητῶν τε καὶ ῥητόρων καὶ μάντεων καὶ ἱερέων καὶ ἄλλων μυριάκις μυρίων, οὐκ ἐπὶ τὸ μὴ δρᾶν τὰ ἄδικα τρεπόμεθα οἱ

that before threatening us harshly, you should first try to convince and teach us, by producing adequate proofs, that gods exist, and that they are too good to be wheedled by gifts and turned aside from justice. For as it is, this and such as this is the account of them we hear from those who are reputed the best of poets, orators, seers, priests, and thousands upon thousands of others; and consequently most of us, instead of seeking to avoid wrong-doing, do the wrong and then try to make it good.
