Context: The progressive world is necessarily divided into two classes — those who take the best of what there is and enjoy it — those who wish for something better and try to create it. Without these two classes the world would be badly off. They are the very conditions of progress, both the one and the other. Were there none who were discontented with what they have, the world would never reach anything better.
                                    
“I divide all readers into two classes: those who read to remember and those who read to forget.”
