Whosoever formeth an intimacy with the enemies of his friends, does so to injure the latter. O wise man! wash your hands of that friend who associates with your enemies.

A wise man among the ignorant is as a beautiful girl in the company of blind men.

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

An enemy to whom you show kindness becomes your friend.

Anger that has no limit causes terror, and unseasonable kindness does away with respect. Be not so severe as to cause disgust, nor so lenient as to make people presume.

It is wrong to follow the advice of an adversary; nevertheless it is right to hear it, that you may do the contrary; and this is the essence of good policy.

To be over much facetious is the accomplishment of courtiers and blemish of the wise.
