A successful book is not made of what is in it, but what is... - Mark Twain

"Education: that which reveals to the wise, and conceals from the stupid, the vast limits of their knowledge."

"If books are not good company, where shall I find it?"

"The fear of death follows from the fear of life. A man who lives fully is prepared to die at any time."

"We have not the reverent feeling for the rainbow that the savage has, because we know how it is made. We have lost as much as we gained by prying into that matter."

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