I confess that I never succeeded in gathering any measure of interest for chronological debates, especially when the whole discussion starts from what I believe to be an exegetical mistake (in this case, connecting the start of the 70 weeks in Daniel 9 with the reconstruction of Jerusalem's walls under Artaxerxes' rule). But (to wobble's question) I found looking at Furuli's personal chronology (he's got a Wiki entry: http://en.wikipedia.org/wiki/Rolf_Furuli) quite instructive. For some reason (maybe because of his position as "lecturer" and the fact he apparently hadn't got a PhD until recently; I still don't know if he has) I pictured him as a relatively young scholar and I really wondered how he could corner himself at an early stage of his career with often desperate WT apologetics within (e.g. Hebrew verbal syntax) or outside (e.g. Persian chronology) of his own academic field. The dates in his bio- and bibliography, if correct, suggest that he is first of all a JW, whose "career" was mainly within the WT organization (travelling overseer in the 70s) before he engaged in scholarship (first publication in 1995 is his MA dissertation, at 53; he's 67 now); also that the defense of WT chronology was actually his first interest (1984, after Jonsson I suppose), prior to his academic training in a different field (Semitic languages).
Disclaimer: this is admittedly off the main topic of this thread, hence not an (ad hominem) argument at all. As a complete outsider to the field of Persian chronology I would rather watch the reception (or lack thereof) of Furuli's thesis by specialists of that field (I vaguely remember one such review has been posted before, and it was mostly negative). This is not a personal attack either. I don't know Furuli, and from what I read he comes across as a bright, sincere and comparatively reasonable JW. But still a (nearly) 100 % committed JW.
