The invisible hand is not perfect. Indeed, the invisible hand is a little bit arthritic ... I'm a believer in free markets, but I think we need to be less naïve. We need to accept that markets give us pretty good solutions, but occasionally they will lock in something inferior.

Complexity is looking at interacting elements and asking how they form patterns and how the patterns unfold. It's important to point out that the patterns may never be finished. They're open-ended. In standard science this hit some things that most scientists have a negative reaction to. Science doesn't like perpetual novelty.

We're facing a danger that economics is rigorous deduction based upon faulty assumptions. Science after science gets that way from time to time. When it does, we're in real trouble.
