Plato, Laws 864c

νῦν φαμεν· οἷς νόμους διαφέροντας ἀλλήλων πέντε εἴδεσιν θετέον ἐν δυοῖν γένεσιν. τίσιν τούτοις; τὸ μὲν διὰ βιαίων καὶ συμφανῶν πράξεων πραττόμενον ἑκάστοτε, τὸ δὲ μετὰ σκότους καὶ ἀπάτης λαθραίως γιγνόμενον, ἔστιν δʼ ὅτε καὶ διʼ ἀμφοῖν τούτοιν πραχθέν· ᾧ δὴ καὶ νόμοι τραχύτατοι γίγνοιντο ἄν, εἰ τὸ προσῆκον μέρος ἔχοιεν. εἰκὸς γοῦν. ἴωμεν δὴ τὰ μετὰ ταῦτα ἐκεῖσε ὁπόθεν ἐξέβημεν δεῦρο, περαίνοντες τὴν θέσιν τῶν νόμων. ἦν δὲ ἡμῖν

we must enact distinct laws, of two main types. What are they? The one concerns acts done on each occasion by violent and open means, the other acts done privily under cover of darkness and deceit, or sometimes acts done in both these ways,—and for acts of this last kind the laws will be most severe, if they are to prove adequate. Naturally. Let us revert next to that point from which we digressed, and proceed with our enactment of the laws.
