Where are you located and how soon do you need it? I may have the possibility of getting the relevant sections to you some way. The article I wrote on the "Refutation" is a short summary, but doesn't give all of the information. It would be a shame if you had do redo the work I did, and I would be very interested in hearing about any new ideas, as well as corrections, that you have on what I wrote. I have not had time to return to this aspect of Abu Ra'ita, but I think it is very much worth researching.
