"But we do the contrary of this; and moreover, if any one be suspected of speaking with a view to his own advantage, though at the same time what is best, through grudging him the gain of which we have but an uncertain idea, we deprive the state of its certain benefit.
And thus good advice, given in a straightforward manner, has come to be no less suspected than bad; so that it is equally necessary for one who wishes to carry the most dreadful measures to win over the multitude by trickery, and for one who speaks on the better side to gain credit by falsehood.
