I very much want to write a follow-up that would go into less detail on elementary particle physics and quantum mechanics, and would discuss much more issues of emergence, issues of evolution, cultural evolution as well as biological, but primarily would go into regularity versus randomness, and complex adaptive systems and the… the identification by complex adaptive systems of what to them is regularity and what is randomness. Because it does depend on what complex adaptive system is observing the entity under consideration, what is regularity and what is randomness. I like to use the example of neckties; of course we don't wear them here, but four-in-hand neckties. A necktie may have a very simple pattern, just a few stripeswhich are very easily… with the regularities of that necktie very easy to describe; or you may have a very complex necktie, such as the ones that were fashionable a few years ago where it would take a very long time to describe the regularities in the pattern. But how do you know we're concerned with a pattern? How… why is the pattern where the regularities reside? I mean we would say that the soup stains don't matter, it's just the pattern. The little irregularities in the weave don't matter, it's just the pattern. But if you're a dry cleaner, it's only the stains that matter, are they soup stains, ink stains, blood stains, and so on; dry cleaners are notoriously insensitive to the pattern, they care only about the stains. So it depends on the complex adaptive system that's observing, what is treated as irregularity and what is treated as randomness and so on. I think that's a very deep set of issues and I'd love to write about them, but getting the leisure to do so is not so easy.
