Calumniae non temere credundum

The engines that they use against the hearer are deceit, lying, perjury, insistence, impudence, and a thousand other unprincipled means; but the most important of all is flattery, a bosom friend, yes, an own sister to slander. Nobody is so high-minded and has a soul so well protected by walls of adamant that he cannot succumb to the assaults of flattery, especially when he is being undermined and his foundations sapped by slander.
All this is on the outside, while on the inside there are many traitors who help the enemy, holding out their hands to him, opening the gates, and in every way furthering the capture of the hearer. First there is fondness for novelty, which is by nature common to all mankind, and ennui also; and secondly, a tendency to be attracted by startling rumours. Somehow or other we all like to hear stories that are slyly whispered in our ear, and are packed with innuendo: indeed, I know men who get as much pleasure from having their ears titillated with slander as some do from being tickled with feathers.
Therefore, when the enemy falls on with all these forces in league with him, he takes the fort by storm, I suppose, and his victory cannot even prove difficult, since nobody mans the walls or tries to repel his attacks. No, the hearer surrenders of his own accord, and the slandered person is not aware of the design upon him: slandered men are murdered in their sleep, just as when a city is captured in the night.
The saddest thing of all is that the slandered man, unaware of all that has taken place, meets his friend cheerfully, not being conscious of any misdeed, and speaks and acts in his usual manner, when he is beset on every side, poor fellow, with lurking foes. The other, if he is noble, gentlemanly, and outspoken, at once lets his anger burst out and vents his wrath, and then at last, on permitting a defence to be made, finds out that he was incensed at_ his friend for nothing.
