Despite the overuse of the word in movies, political speeches, and news reports, “evil” is generally seen as either flagrant rhetoric or else an outdated concept: a medieval holdover with no bearing on our complex everyday reality. In A Philosophy of Evil, however, acclaimed philosopher Lars Svendsen argues that evil remains a concrete moral problem: that we’re all its victims, and all guilty of committing evil acts.”It’s normal to be evil,” he writes—the problem is, we’ve lost the vocabulary to talk about it.Taking up this problem—how do we speak about evil?—A Philosophy of Evil treats evil as an ordinary aspect of contemporary life, with implications that are moral, practical, and above all, political. Because, as Svendsen says, “Evil should neither be justified nor explained away—evil must be fought.”
