I can tell the kind of effect The Dark Knight is having from the fact that, even though I haven’t seen it, I keep running across reasons to blog about it. Whatever one’s opinion of the movie itself, it’s undeniably sparking some thoughtful people to write some perceptive analyses of evil, the human heart, and our Western culture. The latest is a piece by National Review‘s managing editor, Jason Lee Steorts, on the magazine’s website called “Lessons from the Joker”; it’s an interesting meditation on the Joker, moral relativism, the nature of vandalism, and the way to make moral arguments to those who don’t think they believe there’s any such thing as right and wrong. I won’t try to summarize it—I’m still pondering it, at this point; but I encourage you to read it.
