sIfirst read this book back in '76 and it made quite an impression. I finely re-read it this past week and now I'm not so sure. All of it seemed so new back then and struck me as a most likely hypothesis. This read-through was painful....all the four syllable words and pseudo-blah-blah makes you wonder if Eckert wasn't paid by the pound. I still believe the theory is on the right track and have read other research on threads from the book. a surprising amount of this has turned on ats and i'm sure there'll be more that would contribute to the subject.
