de ingenuis moribus et liberalibus adulescentiae studiis, XII:
“They desire to excel, and in their eagerness to appear to know many things, they are rather apt to reveal secrets; and, in thus throwing themselves about, they are often discovered to be liars. At the same time, because they lack experience, they are most frequently deceived when they think that they are speaking the truth.”
appetunt enim excellere, propter quod volentes videri multa nosse, faciles sunt operta revelare, et seipsos iactantes, plerumque mendaces inveniuntur. Simul et quia inexperti sunt, existimantes vera dicere, in plurimis falluntur.
