Book III Of the Principles of the Three Kinds of Government
Chapter 3 Of the Principle of Democracy
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.
What I have here advanced is confirmed by the entire body of history, and is extremely agreeable to the nature of things. For it is clear that in a monarchy, where he who commands the execution of the laws generally thinks himself above them, there is less need of virtue than in a popular government, where the person entrusted with the execution of the laws is sensible of his being subject to their direction.
Clear is it also that a monarch who, through bad advice or indolence, ceases to enforce the execution of the laws, may easily repair the evil; he has only to follow other advice; or to shake off this indolence. But when, in a popular government, there is a suspension of the laws, as this can proceed only from the corruption of the republic, the state is certainly undone.
A very droll spectacle it was in the last century to behold the impotent efforts of the English towards the establishment of democracy. As they who had a share in the direction of public affairs were void of virtue; as their ambition was inffamed by the success of the most daring of their members;  as the prevailing parties were successively animated by the spirit of faction, the government was continually changing: the people, amazed at so many revolutions, in vain attempted to erect a democracy. At length, when the country had undergone the most violent shocks, they were obliged to have recourse to the very government which they had so wantonly proscribed.
When Sylla thought of restoring Rome to her liberty, this unhappy city was incapable of receiving that blessing. She had only the feeble remains of virtue, which were continually diminishing. Instead of being roused from her lethargy by Cæsar, Tiberius, Caius Claudius, Nero, and Domitian, she riveted every day her chains; if she struck some blows, her aim was at the tyrant, not at the tyranny.
The politic Greeks, who lived under a popular government, knew no other support than virtue. The modern inhabitants of that country are entirely taken up with manufacture, commerce, finances, opulence, and luxury.
When virtue is banished, ambition invades the hearts 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.
Athens was possessed of the same number of forces when she triumphed so gloriously as when with such infamy she was enslaved. She had twenty thousand citizens  when she defended the Greeks against the Persians, when she contended for empire with Lacedaemonia, and invaded Sicily. She had twenty thousand when Demetrius of Phalereus numbered them  as slaves are told by the head in a market-place. When Philip attempted to lord it over Greece, and appeared at the gates of Athens  she had even then lost nothing but time. We may see in Demosthenes how difficult it was to awaken her; she dreaded Philip, not as the enemy of her liberty, but of her pleasures.  This famous city, which had withstood so many defeats, and having been so often destroyed had as often risen out of her ashes, was overthrown at Chæronea, and at one blow deprived of all hopes of resource. What does it avail her that Philip sends back her prisoners, if he does not return her men? It was ever after as easy to triumph over the forces of Athens as it had been difficult to subdue her virtue.
How was it possible for Carthage to maintain her ground? When Hannibal, upon his being made prætor, endeavoured to hinder the magistrates from plundering the republic, did not they complain of him to the Romans? Wretches, who would fain be citizens without a city, and be beholden for their riches to their very destroyers! Rome soon insisted upon having three hundred of their principal citizens as hostages; she obliged them next to surrender their arms and ships; and then she declared war.  From the desperate efforts of this defenceless city, one may judge of what she might have performed in her full vigour, and assisted by virtue.
Chapter 4 Of the Principle of Aristocracy
As virtue is necessary in a popular government, it is requisite also in an aristocracy. True it is that in the latter it is not so absolutely requisite.
The people, who in respect to the nobility are the same as the subjects with regard to a monarch, are restrained by their laws. They have, therefore, less occasion for virtue than the people in a democracy. But how are the nobility to be restrained? They who are to execute the laws against their colleagues will immediately perceive that they are acting against themselves. Virtue is therefore necessary in this body, from the very nature of the constitution.
An aristocratic government has an inherent vigour, unknown to democracy. The nobles form a body, who by their prerogative, and for their own particular interest, restrain the people; it is sufficient that there are laws in being to see them executed.
But easy as it may be for the body of the nobles to restrain the people, it is difficult to restrain themselves.  Such is the nature of this constitution, that it seems to subject the very same persons to the power of the laws, and at the same time to exempt them.
Now such a body as this can restrain itself only in two ways; either by a very eminent virtue, which puts the nobility in some measure on a level with the people, and may be the means of forming a great republic; or by an inferior virtue, which puts them at least upon a level with one another, and upon this their preservation depends.
Moderation is therefore the very soul of this government; a moderation, I mean, founded on virtue, not that which proceeds from indolence and pusillanimity.
Chapter 5 That Virtue is Not the Principle of a Monarchical Government
In monarchies, policy effects great things with as little virtue as possible. Thus in the nicest machines, art has reduced the number of movements, springs, and wheels.
The state subsists independently of the love of our country, of the thirst of true glory, of self-denial, of the sacrifice of our dearest interests, and of all those heroic virtues which we admire in the ancients, and to us are known only by tradition.
The laws supply here the place of those virtues; they are by no means wanted, and the state dispenses with them: an action performed here in secret is in some measure of no consequence.
Though all crimes be in their own nature public, yet there is a distinction between crimes really public and those that are private, which are so called because they are more injurious to individuals than to the whole society.
Now in republics private crimes are more public, that is, they attack the constitution more than they do individuals; and in monarchies, public crimes are more private, that is, they are more prejudicial to the fortunes of private people than to the constitution of the state itself.
I beg that no one will be offended with what I have been saying; my observations are founded on all the histories. I am not ignorant that virtuous princes are so very rare; but I venture to affirm that in a monarchy it is extremely difficult for the people to be virtuous. 
Let us compare what the historians of all ages have asserted concerning the courts of monarchs; let us recollect the conversations and sentiments of people of all countries, in respect to the wretched character of courtiers, and we shall find that these are not airy speculations, but truths confirmed by a sad and melancholy experience.
Ambition in idleness; meanness in pride; a desire of riches without industry; aversion to truth; flattery, perfidy, violation of engagements, contempt of the duties of a citizen, fear of the prince's virtue, hope from his weakness, but, above all, a perpetual ridicule cast upon virtue, are, I think, the characteristics by which most courtiers in all ages and countries have been constantly distinguished. Now, it is exceedingly difficult for the leading men of the state to be knaves, and the inferior sort to be honest; for the former to be cheats, and the latter to rest satisfied with being only dupes.
But if there should chance to be some unlucky good man  among the people. Cardinal Richelieu, in his political testament, seems to hint that a prince should take care not to employ him.  So true is it that virtue is not the spring of this government! It is not indeed excluded, but it is not the spring of government.
Chapter 6 In What Manner Virtue is Supplied in a Monarchical Government
But it is high time for me to have done with this subject, lest I should be suspected of writing a satire against monarchical government. Far be it from me; if monarchy wants one spring, it is provided with another. HONOUR, that is, the prejudice of every person and rank, supplies the place of the political virtue of which I have been speaking, and is everywhere her representative: here it is capable of inspiring the most glorious actions, and, joined with the force of laws, may lead us to the end of government as well as virtue itself.
Hence, in well-regulated monarchies, they are almost all good citizens, and very few good men; for to be a good man  a good intention is necessary,  and we should love our country, not so much on our own account, as out of regard to the community.
Chapter 7 Of the Principle of Monarchy
A monarchical government supposes, as we have already observed, pre-eminences and ranks, as likewise a noble descent. Now since it is the nature of honour to aspire to preferences and distinctions, it is properly placed in this government.
Ambition is pernicious in a republic. But in a monarchy it has some good effects; it gives life to the government, and is attended with this advantage, that it is in no way dangerous, because it may be continually checked.
It is with this kind of government as with the system of the universe, in which there is a power that constantly repels all bodies from the centre, and a power of gravitation that attracts them to it. Honour sets all the parts of the body politic in motion, and by its very action connects them; thus each individual advances the public good, while he only thinks of promoting his own interest.
True it is that, philosophically speaking, it is a false honour which moves all the parts of the state; but even this false honour is as useful to the public as true honour could possibly be to private persons.
Is it not very exacting to oblige men to perform the most difficult actions, such as require an extraordinary exertion of fortitude and resolution, without other recompense than that of glory and applause?
Chapter 8 That Honour is Not the Principle of Despotic Government
Honour is far from being the principle of despotic government: mankind being here all upon a level, no one person can prefer himself to another; and as on the other hand they are all slaves, they can give themselves no sort of preference.
Besides, as honour has its laws and rules, as it knows not how to submit; as it depends in a great measure on a man's own caprice, and not on that of another person; it can be found only in states in which the constitution is fixed, and where they are governed by settled laws.
How can despotism abide with honour? The one glories in the contempt of life; and the other is founded on the power of taking it away. How can honour, on the other hand, bear with despotism? The former has its fixed rules, and peculiar caprices; but the latter is directed by no rule, and its own caprices are subversive of all others.
Honour, therefore, a thing unknown in arbitrary governments, some of which have not even a proper word to express it,  is the prevailing principle in monarchies; here it gives life to the whole body politic, to the laws, and even to the virtues themselves.
As virtue is necessary in a republic, and in a monarchy honour, so fear is necessary in a despotic government: with regard to virtue, there is no occasion for it, and honour would be extremely dangerous.
Here the immense power of the prince devolves entirely upon those whom he is pleased to entrust with the administration. Persons capable of setting a value upon themselves would be likely to create disturbances. Fear must therefore depress their spirits, and extinguish even the least sense of ambition.
A moderate government may, whenever it pleases, and without the least danger, relax its springs. It supports itself by the laws, and by its own internal strength. But when a despotic prince ceases for one single moment to uplift his arm, when he cannot instantly demolish those whom he has entrusted with the highest employments,  all is over: for as fear, the spring of this government, no longer subsists, the people are left without a protector.
It is probably in this sense the Cadis maintained that the Grand Seignior was not obliged to keep his word or oath, when he limited thereby his authority. 
It is necessary that the people should be judged by laws, and the great men by the caprice of the prince, that the lives of the lowest subject should be safe, and the pasha's head ever in danger. We cannot mention these monstrous governments without horror. The Sophi of Persia, dethroned in our days by Mahomet, the son of Miriveis, saw the constitution subverted before this resolution, because he had been too sparing of blood. 
History informs us that the horrid cruelties of Domitian struck such a terror into the governors that the people recovered themselves a little during his reign.  Thus a torrent overflows one side of a country, and on the other leaves fields untouched on the other, where the eye is refreshed by the prospect of fine meadows.
