Plato, Laws 718c

αὑτῷ τε καὶ ἐκείνοις οἷς νομοθετήσει, τὰ λοιπὰ πάντα εἰς δύναμιν διεξελθόντα, τὸ μετὰ τοῦτο ἄρχεσθαι τῆς θέσεως τῶν νόμων. ἔστιν δὲ δὴ τὰ τοιαῦτα ἐν τίνι μάλιστα σχήματι κείμενα; οὐ πάνυ ῥᾴδιον ἐν ἑνὶ περιλαβόντα εἰπεῖν αὐτὰ οἷόν τινι τύπῳ, ἀλλʼ οὑτωσί τινα τρόπον λάβωμεν, ἄν τι δυνώμεθα περὶ αὐτῶν βεβαιώσασθαι. λέγε τὸ ποῖον. βουλοίμην ἂν αὐτοὺς ὡς εὐπειθεστάτους πρὸς ἀρετὴν εἶναι, καὶ δῆλον ὅτι πειράσεται τοῦτο ὁ νομοθέτης ἐν ἁπάσῃ ποιεῖν τῇ νομοθεσίᾳ.

for whom he is legislating, and, after expounding all other matters as best he can, pass on next to commencing the task of legislation. What is the special form in which such matters are laid down? It is by no means easy to embrace them all in a single model of statement (so to speak) but let us conceive of them in some such way as this, in case we may succeed in affirming something definite about them. Tell us what that something is. I should desire the people to be as docile as possible in the matter of virtue; and this evidently is what the legislator will endeavor to effect in all his legislation.
