世界称之为不道德的书，是那些向世界展示其自身羞耻的书。
The books that the world calls immoral are books that show the world its own shame.
Happiness and unhappiness depend upon the opinion we have of things.
夢は、追いかけるものではなく、追いかけてくるものだ。
"The act of writing is an act of discovery."
"The world is a book, and those who do not travel read only one page."
