In his Petersburg world all people were divided into utterly opposed classes. One, the lower class, vulgar, stupid, and, above all, ridiculous people, who believe that one husband ought to live with the one wife whom he has lawfully married; that a girl should be innocent, a woman modest, and a man manly, self-controlled, and strong; that one ought to bring up one’s children, earn one’s bread, and pay one’s debts; and various similar absurdities. This was the class of old-fashioned and ridiculous people. But there was another class of people, the real people. To this class they all belonged, and in it the great thing was to be elegant, generous, plucky, gay, to abandon oneself without a blush to every passion, and to laugh at everything else.
— Anna Karenina by Leo Tolstoy
