It's not mine, and it's a long story. The short version is that a chap I know - nowin his 70s - never finished his PhD. We were chatting about the SWH and linguistic relativism and he mentioned it. I asked to see it, he loaned it to me - with permission to copy - provided I never made any of it public.

I'm slowly trying to persuade him that it wouldn't be a bad thing, but it's slow work. He also has the early symptoms of Alzheimer's, so it may never happen.
