“Keep the extent of your abilities unknown.The wise man does not allow his knowledge and abilities to be sounded to the bottom, if he desires to be honored at all. He allows you to know them but not to comprehend them. No one must know the extent of his abilities, lest he be disappointed. No one ever has an opportunity of fathoming him entirely. For guesses and doubts about the extent of his talents arouse more veneration than accurate knowledge of them, be they ever so great.”

“Real knowledge is to know the extent of one's ignorance.”

“The footman burst in, announcing, 'Monsieur le Duc de ---.''Hold your tongue, you fool,' said the Duke as he entered the room.

“For every man in the world functions to the best of his ability, and no one does less than his best, no matter what he may think about it.”

“The aim of our orator, then, when speaking of things that are just and holy and good--and he should not speak of anything else--the aim, as I say, that he pursues to the best of his ability when he speaks of these things is to be listened to with understanding, with pleasure, and with obedience. He should be in no doubt that any ability he has and however much he has derives more from his devotion to prayer than his dedication to oratory; and so, by praying for himself and for those he is about to address, he must become a man of prayer before becoming a man of words.”
