For nearly all of history, people’s lives have been governed primarily by ignorance. … Failures of ignorance we can forgive. If the knowledge of the best thing to do in a given situation does not exist, we are happy to have people simply make their best effort. But if the knowledge exists and is not applied correctly, it is difficult not to be infuriated. … It is not for nothing that philosophers gave these failures so unmerciful a name—ineptitude.
