Fools learn nothing from wise men, but wise men learn much from fools.

Depend on no man, on no friend but him who can depend on himself. He only who acts conscientiously toward himself, will act so toward others.

He who has not forgiven an enemy has not yet tasted one of the most sublime enjoyments of life.

Who makes quick use of the moment is a genius of prudence.

What do I owe to my times, to my country, to my neighbors, to my friends? Such are the questions which a virtuous man ought often to ask himself.

Great minds comprehend more in a word, a look, a pressure of the hand than ordinary men in long conversations, or the most elaborate correspondence.

Trust him not with your secrets, who, when left alone in your room, turns over your papers.

He who seldom speaks, and with one calm well-timed word can strike dumb the loquacious, is a genius or a hero.

He alone is an acute observer, who can observe minutely without being observed.

Don't speak evil of someone if you don't know for certain, and if you do know ask yourself, why am I telling it?

You may depend upon it that he is a good man whose intimate friends are all good, and whose enemies are decidedly bad.

Where there is much pretension, much has been borrowed; nature never pretends.

He who can conceal his joys, is greater than he who can hide his griefs.

Intuition is the clear conception of the whole at once.
