"This man, who for twenty-five years has been reading and writing about art, and in all that time has never understood anything about art, has for twenty-five years been hashing over other people's ideas about realism, naturalism and all that nonsense; for twenty-five years he has been reading and writing about what intelligent people already know and about what stupid people don't want to know--which means that for twenty-five years he's been taking nothing and making nothing out of it. And with it all, what conceit! What pretension!"
