Peter, this is very interesting, thank you! Is this the entire book or just an extract? It seems to end abruptly.
BTW, in order to download it directly from Academia.edu, one must have an account. For those who don't already have an account, it's free to create one, but I recommend checking and adjusting the notification and privacy settings carefully; otherwise you will get a lot of email from them. I've had an account for about 10 years. I use a disposable email address that I can turn off at any time. When you click to download the file, just ignore the option to "download your PDF package" and click the fine print which says, "No thanks, I just want this paper."
Thanks also for offering to provide the PDF for those who don't have an account.
