@ Jag. Jim said on the Harker thread that it was the most difficult book he had ever read. This was about 30 years ago. I don't see what was particularly difficult about it, especially for somebody presumably familiar with the class based approach of A L Lloyd. Not compared with some material we have looked at. And in view of the fact that much of what Harker says had been said before, especially about some of the mediators. But I don't get the feeling that Jim remembers what the book said or its argument or much detail, and that this affects the responses he makes to people trying to discuss it as well as the aspects mentioned by Jeri in the post above.
