Moderately amusing the first time you read it, but he's been banging on about it in book after book. Mocking French intellectual poseurs is fair game I guess, but then he started having a go at Feyerabend? Oh dear.
Thanks for the link, I'll have a read later; sadly Feyerabend won't take up your invitation, he died in `94, but if you have a slot in your book schedule, do have a look at Against Method, astonishing (and entertaining).
