The greatest thing that helps to make regimes lasting is education relative to the regime. This means not that democratic people should be educated democratically, but rather that they should be educated oligarchically, and vice versa, to counteract the natural tendency of the regime toward its extreme form. The problem with democracies is that they define freedom badly. In monarchy, the causes of revolution are as follows. Kingship and tyranny are distinguished from one another in that the tyrant seeks his own pleasure while the king seeks noble goals.
Tyranny encompasses the evils of both democracy and oligarchy.
Attacks on monarchs occur sometimes because of their disgraceful behavior to others, or because of fear, contempt, ambition, or desire for profit. Tyranny is often destroyed from the outside by a superior regime. It is also destroyed from within when the rulers fall into factional conflict. Kingship is rarely destroyed from outside. Kingships are preserved by limiting the king's authority.
