Calumniae non temere credundum

As you see, flattery and slander were most likely to find an opening when they were framed with reference to Alexander's weak point. In a siege the enemy do not attack the high, sheer and secure parts of the wall, but wherever they notice that any portion is unguarded, unsound or low, they move all their forces against that place because they can very easily get in there and take the city. Just so with slanderers: they assail whatever part of the soul they perceive to be weak, unsound and easy of access, bringing their siege-engines to bear on it

and finally capturing it, as no one opposes them or notices their assault. Then, when they are once within the walls, they fire everything and smite and slay and banish ; for all these things are likely to happen when the soul is captured and put in bondage.
