Sometimes it feels as if the world is divided into two classes: one very large class spurns difficulty, while the other very much smaller delights in it. There are readers who, when encountering an unfamiliar word, instead of reaching for a dictionary, choose to regard it as a sign of the author’s contempt or pretension, a deliberate refusal to speak in a language ordinary people can understand.

Others, encountering the same word, happily seize on it as a chance to learn something new, to broaden their horizons. They eagerly seek a literature that upends assumptions, challenges prejudices, turns them inside out and forces them to see the world through new eyes.
