Monarchies, in a word, are preserved by means contrary to what I have already mentioned as the cause of their destruction; but to speak to each separately: the stability of a kingdom will depend upon the power of the king's being kept within moderate bounds; for by how much the less extensive his power is, by so much the longer will his government continue; for he will be less despotic and more upon an equality of condition with those he governs; who, on that account, will envy him the less.
