Is it true, prince, that you once declared that ‘beauty would save the world’? Great Heaven! The prince says that beauty saves the world! And I declare that he only has such playful ideas because he’s in love! Gentlemen, the prince is in love. I guessed it the moment he came in. Don’t blush, prince; you make me sorry for you. What beauty saves the world? Colia told me that you are a zealous Christian; is it so? Colia says you call yourself a Christian.” The prince regarded him attentively, but said nothing.
From The Idiot by Fyodor Dostoyevsky.
