Men of sense often learn from their enemies. It is from their foes, not their friends, that cities learn the lesson of building high walls and ships of war.

Youth ages, immaturity is outgrown, ignorance can be educated, and drunkenness sobered, but stupid lasts forever.

Your lost friends are not dead, but gone before, advanced a stage or two upon that road which you must travel in the steps they trod.

High thoughts must have high language.

Ignorance can be cured, but stupidity is forever

By words the mind is winged.

The wise learn many things from their enemies.
