Wisdom is harder to DO than it is to know.
Great wisdom is generous petty wisdom is contentious. Great speech is impassioned, small speech cantankerous.
Wisdom is a variable possession. Every man is wise when pursued by a mad dog, fewer when pursued by a mad woman; only the wisest survive when attacked by a mad notion.
It requires wisdom to understand wisdom the music is nothing if the audience is deaf.
Wisdom doesn’t necessarily come with age. Sometimes age just shows up all by itself.
When I can look life in the eyes, grown calm and very coldly wise, life will have given me the truth, and taken in exchange – my youth.
He who devotes sixteen hours a day to hard study may become at sixty as wise as he thought himself at twenty.
