Plato, Laws 709d

οὐκοῦν ὅ γε πρὸς ἕκαστόν τι τῶν εἰρημένων ἔχων τὴν τέχνην κἂν εὔξασθαί που δύναιτο ὀρθῶς, τί παρὸν αὐτῷ διὰ τύχης, τῆς τέχνης ἂν μόνον ἐπιδέοι; πάνυ μὲν οὖν. οἵ τε ἄλλοι γε δὴ πάντες οἱ νυνδὴ ῥηθέντες, κελευόμενοι τὴν αὑτῶν εὐχὴν εἰπεῖν, εἴποιεν ἄν. ἦ γάρ; τί μήν; ταὐτὸν δὴ καὶ νομοθέτης οἶμαι δράσειεν. ἔγωγʼ οἶμαι. φέρε δή, νομοθέτα, πρὸς αὐτὸν φῶμεν, τί σοι

Very true. Would not, then, the man who possessed art in regard to each of the crafts mentioned be able to pray aright for that condition which, if it were given by Chance, would need only the supplement of his own art? Certainly. And if all the other craftsmen mentioned just now were bidden to state the object of their prayers, they could do so, could they not? Of course. And the lawgiver, I suppose, could do likewise? I suppose so. Come now, O lawgiver, let us say to him, what are we to give you, and what condition of State, to enable you, when you receive it, thence-forward to manage the State by yourself satisfactorily?
