Many things are unknown to the wisest, and the best men can never wholly divest themselves of passions and affections... nothing can or ought to be permanent but that which is perfect.

We cannot distinguish truth from falsehood, right from wrong, or know what obedience we owe to the magistrate, or what we may justly expect from him, unless we know what he is, why he is, and by whom he is made to be what he is.... I cannot know how to obey unless I know in what, and to whom; nor in what unless I know what ought to be commanded; nor what ought to be commanded unless I understand the original right of the commander, which is the great arcanum.

Machiavel, discoursing on these matters, finds virtue to be so essentially necessary to the establishment and preservation of liberty, that he thinks it impossible for a corrupted people to set up a good government, or for a tyranny to be introduced if they be virtuous; and makes this conclusion, 'That where the matter (that is, the body of the people) is not corrupted, tumults and disorders do not hurt; and where it is corrupted, good laws do no good:' which being confirmed by reason and experience, I think no wise man has ever contradicted him.

Nay, all laws must fall, human societies that subsist by them be dissolved, and all innocent persons be exposed to the violence of the most wicked, if men might not justly defend themselves against injustice by their own natural right, when the ways prescribed by publick authority cannot be taken.

Fruits are always of the same nature with the seeds and roots from which they come, and trees are known by the fruits they bear: as a man begets a man, and a beast a beast, that society of men which constitutes a government upon the foundation of justice, virtue, and the common good, will always have men to promote those ends; and that which intends the advancement of one man's desire and vanity, will abound in those that will foment them.

That is the best Government, which best provides for war.

[A]ll popular and well-mixed governments [republics] . . . are ever established by wise and good men, and can never be upheld otherwise than by virtue: The worst men always conspiring against them, they must fall, if the best have not power to preserve them. . . . [and] unless they be preserved in a great measure free from vices . . . .
