“And, indeed, if the intellectual ability of kings and magistrates were exerted to the same degree in peace as in war, human affairs would be more orderly and settled, and you would not see governments shifted from hand to hand, and things universally changed and confused. For dominion is easily secured by those qualities by which it was at first obtained. But when sloth has introduced itself in the place of industry, and covetousness and pride in that of moderation and equity, the fortune of a state is altered together with its morals; and thus authority is always transferred from the less to the more deserving.”
Quod si regum atque imperatorum animi virtus in pace ita ut in bello valeret, aequabilius atque constantius sese res humanae haberent neque aliud alio ferri neque mutari ac misceri omnia cerneres. Nam imperium facile iis artibus retinetur, quibus initio partum est. Verum ubi pro labore desidia, pro continentia et aequitate lubido atque superbia invasere, fortuna simul cum moribus inmutatur. Ita imperium semper ad optumum quemque a minus bono transferetur.
