 It gets more and more philosophical, I would have to say. And, you know, I think a lot of the themes of this book, you know, transient and strange, deal with things that are ephemeral and difficult to understand. And, you know, just trying to make sense of meaning in a universe that can be pretty meaningless. It's a very human activity, whether scientists are doing it or whether kids are doing it or whether, you know, you at any age are doing it.
