Plato, Laws 690a

εἶεν· ἀξιώματα δὲ δὴ τοῦ τε ἄρχειν καὶ ἄρχεσθαι ποῖά ἐστι καὶ πόσα, ἔν τε πόλεσιν μεγάλαις καὶ σμικραῖς ἔν τε οἰκίαις ὡσαύτως; ἆρʼ οὐχὶ ἓν μὲν τό τε πατρὸς καὶ μητρός; καὶ ὅλως γονέας ἐκγόνων ἄρχειν ἀξίωμα ὀρθὸν πανταχοῦ ἂν εἴη; καὶ μάλα. τούτῳ δέ γε ἑπόμενον γενναίους ἀγεννῶν ἄρχειν· καὶ τρίτον ἔτι τούτοις συνέπεται τὸ πρεσβυτέρους μὲν ἄρχειν δεῖν, νεωτέρους δὲ ἄρχεσθαι. τί μήν;

Very well then: what and how many are the agreed rights or claims in the matter of ruling and being ruled, alike in States, large or small, and in households? Is not the right of father and mother one of them? And in general would not the claim of parents to rule over offspring be a claim universally just? Certainly. And next to this, the right of the noble to rule over the ignoble; and then, following on these as a third claim, the right of older people to rule and of younger to be ruled. To be sure.
