"The secret source of humor is not joy but sorrow; there is no humor in Heaven."

"′Classic′ - a book which people praise and don't read."

"The reports of my death are greatly exaggerated."

"Good friends, good books and a sleepy conscience: this is the ideal life."

"When we remember we are all mad, the mysteries disappear and life stands explained."
