The sea does not contain all the pearls, the earth does not enclose all the treasures, and the flint-stone does not inclose all the diamonds, since the head of man encloses wisdom.

The wise man tells not what he knows. It is not prudent to sport with one's head by revealing the king's secrets.

Whoever interrupts the conversation of others to make a display of his fund of knowledge, makes notorious his own stock of ignorance.

Great God, have pity on the wicked, for thou didst everything for the good, when thou madest them good!

It's no virtue to gain the whole world. Just gain the heart of one person.

Pride thyself on what virtue thou hast, and not on thy parentage.

Better is the sinner who hath thoughts about God, than the saint who hath only the show of sanctity.
