In Discourses, Sidney reviews the history of governments from Biblical, through Greek, Roman and English eras. In one of its most significant passages, he discusses and analyzes the characteristics of "Good and Bad Magistrates." This selection is quoted verbatim by Trenchard and Gordon in their Cato's Letters (published as pamphlets in Great Britain from 1720-1723) which were popular in the American colonies at the time of the revolution. Sidney's insights into what makes a magistrate (a government leader) "good" or "bad" are still applicable today:
"Reason and experience instruct us, that every man acts according to the end he proposes to himself. The good magistrate seeks the good of the people committed to his care, that he may perform the end of his institution: and knowing that chiefly to consist in justice and virtue, he endeavors to plant and propagate them; and by doing this he procures his own good as well as that of the public. He knows there is no safety where there is no strength, no strength without union, no union without justice; no justice where faith and truth, in accomplishing public and private contracts, is wanting. This he perpetually inculcates, and thinks it a great part of his duty, by precept and example, to educate the youth in a love of virtue and truth, that they may be seasoned with them, and filled with an abhorrence of vice and falsehood, before they attain that age which is exposed to the most violent temptations, and in the which they may, by their crimes, bring great mischiefs upon the public. He would do all this, tho' it were to his own prejudice. But as good actions always carry a reward with them, these contribute in a high measure to his own advantage. By preferring the interest of the people before his own, he gains their affection, and all that is in their power comes with it; whilst he unites them to one another, he unites all to himself: in leading them to virtue, he increases their strength, and by that means provides for his own safety, glory, and power.
"On the other side, such as seek different ends must take different ways. When a magistrate fancies he is not made for the people, but the people for him; that he does not govern for them, but for himself; and that the people live only to increase his glory, or furnish matter for his pleasures; he does not inquire what he may do for them, but what he may draw from them. By this means he sets up an interest of profit, pleasure, or pomp, in himself, repugnant to the good of the public, for which he is made to be what he is. These contrary ends certainly divide the nation into parties; and whilst every one endeavors to advance that to which he is addicted, occasions of hatred for injuries every day done, or thought to be done, and received, must necessarily arise. This creates a most fierce and irreconcilable enmity, because the occasions are frequent, important, and universal, and the causes thought to be most just. The people think it the greatest of all crimes, to convert that power to their hurt, which was instituted for their good; and that the injustice is aggravated by perjury and ingratitude, which comprehend all manner of ill; and the magistrate gives the name of sedition or rebellion to whatsoever they do for the preservation of themselves, and their own rights. When men's spirits are thus prepared, a small matter sets them on fire; but if no accident happens to blow them into a flame, the course of justice is certainly interrupted, the public affairs are neglected; and when any occasion, whether foreign or domestic arises, in which the magistrate stands in need of the people's assistance, they, whose affections are alienated, not only shew an unwillingness to serve him with their persons and estates, but fear that by delivering him from his distress, they strengthen their enemy, and enable him to oppress them; and he, fancying his will to be unjustly opposed, or his due more unjustly denied, is filled with a dislike of what he sees, and a fear of worse of the future. Whilst he endeavors to ease himself of the one, and to provide against the other, he usually increases the evils of both and jealousies are on both sides multiplied. Every man knows that the governed are in a great measure under the power of the governor; but as no man, or number of men, is willingly subject to those who seek their ruin, such as fall in so great a misfortune continue no longer under it than force, fear, or necessity, may be able to oblige them. But as such a necessity can hardly lie longer upon a great people, than till the evil be fully discovered and comprehended, and their virtue, strength, and power, be united to expel it; the ill magistrate looks upon all things, that may conduce to that end, as so many preparatives to his ruin; and by the help of those, who are of his party, will endeavor to prevent that union, and diminish that strength, virtue, power, and courage, which he knows to be bent against him. And as truth, faithful dealing due performance of contracts, and integrity of manners, are bonds of union, and helps to good, he will always by tricks, artifices, cavils, and all means possible, endeavor to establish falsehood and dishonesty; whilst other emissaries and instruments of iniquity, by corrupting the oath, and seducing such as can be brought to lewdness and debauchery, bring the people to such a pass, that they may neither care nor dare to vindicate their rights, and that those who would do it, may so far suspect each other, as not to confer upon, much less to join in, any action tending to the public deliverance.
"This distinguishes the good from the bad magistrate, that faithful from the unfaithful; and those who adhere to either, living in the same principle, must walk in the same ways. They who uphold the rightful power of a just magistracy, encourage virtue and justice; teach men what they ought to do, suffer, or expect from others; fix them upon principles of honesty; and generally advance every thing that tends to the increase of the valour, strength, greatness, and happiness of the nation, creating a good union among them, and bringing every man to an exact understanding of his own and the public rights. On the other side, he that would introduce an ill magistrate, make one evil who was good, or preserve him in the exercise of injustice when he is corrupted, must always open the way for him by vitiating the people, corrupting their manners, destroying the validity of oaths and contracts, teaching such evasions, equivocations, and frauds, as are inconsistent with the thoughts, that become men of virtue and courage; and overthrowing the confidence they ought to have in each other, make it impossible for them to unite among themselves. The like arts must be used with the magistrate: he cannot be for their turn, till he is persuaded to believe he has no dependence upon, and owes no duty to the people; that he is of himself, and not by their institution; that no man ought to inquire into, nor be judge of his actions; that all obedience is due to him, whether he be good or bad, wise or foolish, a father or an enemy to his country. This being calculated for his personal interest, he must pursue the same designs, or his kingdom is divided within itself, and cannot subsist. By this means those who flatter his humor, come to be accounted his friends, and the only men that are thought worthy of great trusts, whilst such as are of another mind are exposed to all persecution. These are always such as excel in virtue, wisdom, and greatness of spirit: they have eyes, and they will always see the way they go; and, leaving fools to be guided by implicit faith, will distinguish between good and evil, and chose that which is best; they will judge of men by their actions, and by them discovering whose servant every man is, know whether he is to be obeyed or not. Those who are ignorant of all good, careless, or enemies to it, take a more compendious way; their slavish, vicious, and base natures, inclining them to seek only private and present advantages, they easily slide into a blind dependence upon one who has wealth and power; and desiring only to know his will, care not what injustice they do, if they may be rewarded. They worship what they find in the temple, tho' it be the vilest of idols; and always like the best which is worst, because it agrees with their inclinations and principles. When a party comes to be erected upon such a foundation, debauchery, lewdness, and dishonesty, are the true badges of it. Such as wear them are cherished; but the principal marks of favor are reserved for those, who are the most industrious in mischief, either by seducing the people with allurements of sensual pleasures, or corrupting their understandings by false and slavish doctrines. By this means, a man who calls himself a philosopher, or a divine, is often more useful than a great number of tapsters, cooks, buffoons, players, fidlers, whores, or bawds. These are the devil's ministers of a lower order; they seduce single persons; and such as fall into their snares, are for the most part men of the simpler sort; but the principal supporters of this kingdom are they, who by false doctrines poison the springs of religion and virtue, and by preaching or writing (if their falsehood and wickedness were not detected) would extinguish all principles of common honesty, and bring whole nations to be best satisfied with themselves, when their actions are most abominable. And as the means must always be suitable to the end proposed, the governments that are to be established or supported by such ways must needs be the worst of all, and comprehend all manner of evil."
