Plato, Laws 693d

what was it you intended to say that the lawgiver ought to aim at? Listen. There are two mother-forms of constitution, so to call them, from which one may truly say all the rest are derived. Of these the one is properly termed monarchy, the other democracy, the extreme case of the former being the Persian polity, and of the latter the Athenian; the rest are practically all, as I said, modifications of these two. Now it is essential for a polity to partake of both these two forms, if it is to have freedom and friendliness combined with wisdom.
