Sono maggiori li spaventi ch'e mali. - Niccolò Machiavelli

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.

There is no other way of guarding against adulation, than to make people understand that they will not offend you by speaking the truth. On the other hand, when everyone feels at liberty to tell you the truth, they will be apt to be lacking in respect to you.

In peace one is despoiled by the mercenaries, in war by one's enemies.
