Plato, Laws 810c

γράμμαθʼ ἡμῖν ἐστιν παρά τινων τῶν πολλῶν τοιούτων ἀνθρώπων καταλελειμμένα· οἷς, ὦ πάντων βέλτιστοι νομοφύλακες, τί χρήσεσθε; ἢ τί ποθʼ ὑμῖν ὁ νομοθέτης χρῆσθαι προστάξας ὀρθῶς ἂν τάξειε; καὶ μάλα ἀπορήσειν αὐτὸν προσδοκῶ. τί ποτε τοῦτο, ὦ ξένε, φαίνῃ πρὸς σαυτὸν ὄντως ἠπορηκὼς λέγειν; ὀρθῶς ὑπέλαβες, ὦ Κλεινία. πρὸς δὲ δὴ κοινωνοὺς ὑμᾶς ὄντας περὶ νόμων ἀνάγκη τό τε φαινόμενον εὔπορον καὶ τὸ μὴ φράζειν.

and some of the many composers of this sort have bequeathed to us writings of a dangerous character. How will you deal with these, O my most excellent Law-wardens? Or what method of dealing with them will the lawgiver rightly ordain? He will be vastly perplexed, I verily believe. What does this mean, Stranger? Evidently you are addressing yourself, and are really perplexed. You are right in your supposition, Clinias. As you are my partners in this investigation of laws, I am bound to explain to you both what seems easy and what hard.
