One of the greatest crimes is to destroy a work of art.

Repentance absolves one from every fault.

Shut no door that you will not be able to open.

The strongest man is he who can fight against himself.

Be respectful alike to your teacher and to those you teach.

Everything must be according to reason, and reason itself must be polite.

Polite manners are the best patrimony that fathers can bequeath to their children.

Master your indignation and the fury of your anger, until your anger leaves you, and wisdom returns.

Anger is a raging fire. Whoever can subdue his anger, puts out the fire: whoever cannot, gets burnt himself.

Beware of anger, which begins from madness, and ends with repentence.
