In this passage we are taught how hateful a thing is calumny in all free States, as, indeed, in every society, and how we must neglect no means which may serve to check it. And there can be no more effectual means for checking calumny than by affording ample facilities for impeachment, which is as useful in a commonwealth as the other is pernicious. And between them there is this difference, that calumny needs neither witness, nor circumstantial proof to establish it, so that any man may be calumniated by any other; but not impeached; since impeachment demands that there be substantive charges made, and trustworthy evidence to support them. Again, it is before the magistrates, the people, or the courts of justice that men are impeached; but in the streets and market places that they are calumniated. Calumny, therefore, is most rife in that State wherein impeachment is least practised, and the laws least favour it. For which reasons the legislator should so shape the laws of his State that it shall be possible therein to impeach any of its citizens without fear or favour; and, after duly providing for this, should visit calumniators with the sharpest punishments. Those punished will have no cause to complain, since it was in their power to have impeached openly where they have secretly calumniated. Where this is not seen to, grave disorders will always ensue. For calumnies sting without disabling; and those who are stung being more moved by hatred of their detractors than by fear of the things they say against them, seek revenge.
This matter, as we have said, was well arranged for in Rome, but has always been badly regulated in our city of Florence. And as the Roman ordinances with regard to it were productive of much good, so the want of them in Florence has bred much mischief. For any one reading the history of our city may perceive, how many calumnies have at all times been aimed against those of its citizens who have taken a leading part in its affairs. Thus, of one it would be said that he had plundered the public treasury, of another, that he had failed in some enterprise because he had been bribed; of a third, that this or the other disaster
