There is no great share of probity necessary to support a monarchical or despotic government. The force of laws in one, and the prince's arm in the other, are sufficient to direct and maintain the whole. But in a popular state, one spring more is necessary, namely, virtue....
When virtue is banished, ambition invades the minds of those who are disposed to receive it, and avarice possesses the whole community. The objects of their desires are changed; what they were fond of before has become indifferent; they were free while under the restraint of laws, but they would fain now be free to act against law; and as each citizen is like a slave who has run away from his master, that which was a maxim of equity he calls rigour; that which was a rule of action he styles constraint; and to precaution he gives the name of fear. Frugality, and not the thirst of gain, now passes for avarice. Formerly the wealth of individuals constituted the public treasure; but now this has become the patrimony of private persons. The members of the commonwealth riot on the public spoils, and its strength is only the power of a few, and the licence of many.
Charles-Louis de Secondat (Baron de Montesquieu), The Spirit of the Laws III.3
