You should read John Allen Paulos’s latest column on complexity — it’s a central concept in the various debates that go on around here, and no one on the other side evinces any sign of actually understanding the subject. It’s always “complexity implies design” this, and “complexity only arises by intent” that. I’ll also second his recommendation of Stuart Kauffman’s At Home in the Universe: The Search for the Laws of Self-Organization and Complexity(amzn/b&n/abe/pwll) — it’s a very good book full of interesting ideas and empirical demonstrations of order arising out of randomness.
Another reason to read the column: the ABC news site gets a more diverse mix of commenters than we do here, and if you want to get a wider sample of the American mindset, they’re much more representative. And far more terrifying.
