Calumniae non temere credundum

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.
