Arrogant men with knowledge make more noise from their mouth than making a sense from their mind.
Kindness is strength. Good-nature is often mistaken for virtue, and good health sometimes passes for genius. Anger blows out the lamp of the mind. In the examination of a great and important question, every one should be serene, slow-pulsed, and calm. Intelligence is not the foundation of arrogance. Insolence is not logic. Epithets are the arguments of malice.
Once he has outgrown his youth, a man will rarely remain a prisoner to his insolence. He had thought it was the only way to behave; then he suddenly discovers that, even for a prince, there are such things as music, literature, not to speak of standing for the post of deputy.
