"Cowen: I was told to come here and tell you all stories, but what I'd like to do is instead tell you why I'm suspicious of stories, why stories make me nervous. In fact, the more inspired a story makes me feel, very often the more nervous I get. So the best stories are often the trickiest ones. The good and bad things about stories is they're a kind of filter. They take a lot of information, and they leave some of it out, and they keep some of it in. But the thing about this filter, it always leaves the same things in. You're always left with the same few stories. There's the old saying, just about every story can be summed up as, "A stranger came to town." There's a book by Christopher Booker, he claims there are really just seven types of stories. There's monster, rags to riches, quest, voyage and return, comedy, tragedy, rebirth. You don't have to agree with that list exactly, but the point is this: if you think in terms of stories, you're telling yourself the same things over and over again."
