Plato, Laws 737b

γὰρ δεῖ τὰς οὐσίας πρὸς ἀλλήλους κατασκευάζεσθαι ἁμῶς γέ πως, ἢ μὴ προϊέναι πρότερον εἰς τοὔμπροσθεν ἑκόντα εἶναι τῆς ἄλλης κατασκευῆς οἷς ᾖ παλαιὰ ἐγκλήματα πρὸς ἀλλήλους, ὅσοις νοῦ καὶ σμικρὸν μετῇ· οἷς δέ, ὡς ἡμῖν νῦν, θεὸς ἔδωκε καινήν τε πόλιν οἰκίζειν καὶ μή τινας ἔχθρας εἶναί πω πρὸς ἀλλήλους, τούτους ἔχθρας αὑτοῖς αἰτίους γενέσθαι διὰ τὴν διανομὴν τῆς γῆς τε καὶ οἰκήσεων οὐκ ἀνθρώπινος ἂν εἴη μετὰ κάκης πάσης ἀμαθία.

otherwise, for people who have ancient disputes with one another, men will not of their own free will proceed any further with political construction, if they have a grain of sense. But as for those to whom—as to us now—God has given a new State to found, and one free as yet from internal feuds,—that those founders should excite enmity against themselves because of the distribution of land and houses would be a piece of folly combined with utter depravity of which no man could be capable.
