“If one hears bad music, it is one's duty to drown it in conversation.”

“If one plays good music, people don't listen, and if one plays bad music people don't talk.”

“I like Wagner's music better than anybody's. It is so loud that one can talk the whole time without other people hearing what one says.”

“The first duty in life is to be as artificial as possible.  What the second duty is no one has as yet discovered.”

“Duty is what one expects from others.”

“The one duty we owe to history is to rewrite it.”

“On an occasion of this kind it becomes more than a moral duty to speak one's mind. It becomes a pleasure.”
