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.
