Is "The Moratorium on Brains" one of the greatest chapters ever written? If you don't remember it's the chapter where the train blows up in the tunnel. The entire chapter is just dazzling, it's one massive cause-and-effect chain, where people keep passing the buck to someone else, and the tension keeps progressively ramping up. It is one of the most extraordinary examples of increasing drama that I've ever seen; we see the moral deliberations of every character in the chain. From the very start, you know what is going to happen, so the entire chapter just has this palpable sense of tragedy.
