Gentlemen, let us suppose that man is not stupid. (Indeed one cannot refuse to suppose that, if only from the one consideration, that, if man is stupid, then who is wise?) But if he is not stupid, he is monstrously ungrateful! Phenomenally ungrateful. In fact, I believe that the best definition of man is the ungrateful biped.
Fyodor DostoevskyNothing could be more absurd than moral lessons at such a moment! Oh, self-satisfied people: with what proud self-satisfaction such babblers are ready to utter their pronouncements! If they only knew to what degree I myself understand all the loathsomeness of my present condition, they wouldn't have the heart to teach me.
