Here's an article from Carl Zimmer talking about how insects create order by following very simple rules. What's interesting is that in the article Zimmer mentions that experiments were run with humans to mimic this order making phenomenon. I couldn't help but wonder why they had to run experiments with humans, because you could easily study human society to find similar spontaneous orders. Medieval law, language, the market process and other aspects of human culture can be traced to individuals following simple rules.
I will have more to say about this in future blog posts when I continue my live blogging of "Law, Legislation, and Liberty."
