Since, then, according to our first method in treating of the different
forms of government, we have divided those which are regular into three
sorts, the kingly, the aristocratical, the free states, and shown
the three excesses which these are liable to: the kingly, of becoming
tyrannical; the aristocratical, oligarchical; and the free state,
democratical: and as we have already treated of the aristocratical and
kingly; for to enter into an inquiry what sort of government is best
is the same thing as to treat of these two expressly; for each of
them desires to be established upon the principles of virtue: and as,
moreover, we have already determined wherein a kingly power and an
aristocracy differ from each other, and when a state may be said to be
governed by a king, it now remains that we examine into a free state,
and also these other governments, an oligarchy, a democracy, and a
[1289b] tyranny; and it is evident of these three excesses which must be
the worst of all, and which next to it; for, of course, the excesses of
the best and most holy must be the worst; for it must necessarily happen
either that the name of king only will remain, or else that the king
will assume more power than belongs to him, from whence tyranny will
arise, the worst excess imaginable, a government the most contrary
possible to a free state. The excess next hurtful is an oligarchy; for
an aristocracy differs much from this sort of government: that which is
least so is a democracy. This subject has been already treated of by one
of those writers who have gone before me, though his sentiments are not
the same as mine: for he thought, that of all excellent constitutions,
as a good oligarchy or the like, a democracy was the worst, but of all
bad ones, the best.
