Like I wrote, I considered the part after the comma a new sentence; the comma as a mistyped period. It's certainly in no way related to the thing before it, unless Wright is both 372 pages covering three parts and 11 chapters and the author of himself. Sorry, I was simply too tired at the time (11:18 PM CET) to consider how to explain the grammar of something that makes no sense. We can of course bicker over how we're supposed to parse the language, but it's certainly not worth the bother: The writing is shit, QED.
Also, trying to give information to an intended reader that most probably does not exist on Slashdot is no excuse for piling on with irrelevant fluff.
