I might check that book out because it sounds interesting, but the Wikipedia article makes him sound like an idiot.
More specifically, this strikes me as absolutely stupid:
"instead of treating cases of ethical or legal deviation as occasions when a person should be taught personal responsibility"
The brain operates through electrical signals and chemical reactions. I'm not an expert, but I think I recall hearing that certain mental illnesses show signs of different activity when we view brain activity. Different parts of the brain can also be shaped/sized slightly differently with disastrous results. Illnesses or even lifelong habits can cause physical changes in the size of different parts of the brain.
Furthermore, as a person with a mental illness, in some ways it seems like its partly a way to categorize people with different personality traits, ways of processing information, etc.
I think there's more to it than assuming that everyone that ever does anything wrong just has a discipline problem. I haven't read the book so I have to withhold judgement, but I'm guessing he's going to turn out to be a quack.
