Good to see stuff from both of you.

My own dark hunch is that Ridley is introducing a book and, bored with Darwin, reaches to complexity and the next rock in his stream. Dawkins, perhaps with the same boredom, was driven to attack religion...a most peculiar move when the UK is a cusp for Islam.

As for "chaos," I don't understand it and, perhaps by definition, no one is supposed to. It becomes a scientific exit line when we don't understand what occurs. Skinner had one answer - when you don't understand what happens, it means you haven't looked at the right stuff.

I still scan the arXiv site for relevant things and every so often, there is a bit of order that I can understand.
