Here is a link to chapter 8 of my book, and an apology.
The apology is because astute readers will notice I posted substantially the same chapter as a stand-alone post back in March. At that time I hadn’t decided to link to the entire book online, and it seemed a relevant topic. Publishing it in sequence here at least enables it to be downloaded in the same pdf format as the other chapters, as well as providing the footnotes.
The fact that I’ve posted another essay this week may be felt to be some compensation!
