Plato, Laws 626c

δοκεῖς μοι λέγειν οὕτω κεκοσμημένην οἰκεῖν δεῖν, ὥστε πολέμῳ νικᾶν τὰς ἄλλας πόλεις. ἦ γάρ; πάνυ μὲν οὖν· οἶμαι δὲ καὶ τῷδε οὕτω συνδοκεῖν. πῶς γὰρ ἂν ἄλλως ἀποκρίναιτο, ὦ θεῖε, Λακεδαιμονίων γε ὁστισοῦν; πότερʼ οὖν δὴ πόλεσι μὲν πρὸς πόλεις ὀρθὸν τοῦτʼ ἐστί, κώμῃ δὲ πρὸς κώμην ἕτερον; οὐδαμῶς. ἀλλὰ ταὐτόν; ναί. τί δέ; πρὸς οἰκίαν οἰκίᾳ τῶν ἐν τῇ κώμῃ, καὶ πρὸς ἄνδρα ἀνδρὶ ἑνὶ πρὸς ἕνα, ταὐτὸν ἔτι; ταὐτόν.

you appear to me to imply that it ought to be organized in such a way as to be victorious in war over all other States. Is that so? Certainly it is; and I think that our friend here shares my opinion. No Lacedaemonian, my good sir, could possibly say otherwise. If this, then, is the right attitude for a State to adopt towards a State, is the right attitude for village towards village different? By no means. It is the same, you say? Yes. Well then, is the same attitude right also for one house in the village towards another, and for each man towards every other? It is.
