The kind of man who always thinks that he is right, that his opinions, his pronouncements, are the final word, when once exposed shows nothing there. But a wise man has much to learn without a loss of dignity.
Men should pledge themselves to nothing; for reflection makes a liar of their resolution.
All a man's affairs become diseased when he wishes to cure evils by evils.
It is no weakness for the wisest man to learn when he is wrong.
Kindness will always attract kindness.
Evil counsel travels fast.
