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.
No one longs to live more than someone growing old.
There is no happiness where there is no wisdom.
Look how men live, always precariously balanced between good and bad fortune.
Let a man nobly live or nobly die.
Knowledge must come through action.
