The thing that’s easy to forget about history is that so much of it is bullshit. It’s the result of modern people trying to piece together the past from fragments, all of it skewed by their own point of view. And that screwed-up understanding of the past changes how we think about the present. For instance, we assume ancient women probably didn’t fight wars or make art because we didn’t allow women to do so until embarrassingly recently.

Who wouldn’t want the fruit of his or her artistic labors to reach and influence the lives of millions? The right book can alter the way its readers think. It can inspire them into action. Sometimes, though, that influence reaches farther and in different directions than the author anticipated. Sometimes, authors grow to hate these publications that make them famous.
