There's a lot we should be able to learn from history. And yet history proves that we never do. In fact, the main lesson of history is that we never learn the lessons of history. This makes us look so stupid that few people care to read it. They'd rather not be reminded. Any good history book is mainly just a long list of mistakes, complete with names and dates. It's very embarrassing.
