The Republic - pg. 222

"It won't be hard for you to hear them," I said. "For those
I mean are also the ones having names; the one that is
praised by the many, that Cretan and Laconian regime;
and second in place and second in praise, the one called oligarchy,
a regime filled with throngs of evils; and this regime's
adversary, arising next in order, democracy; and then the
noble tyranny at last, excelling all of these, the fourth and
extreme illness of a city.. Or have you some other >idea
of a regime and dits into some distinct form? For dynasties
and purchased kingships and certain regimes of the sort
are somewhere between these, and one would find them
no less among the barbarians than the Greeks."
