Lest it be forgotten, this now extensive and multi-named thread began with my simple suggestion, in response to a P.S. in a post by Sabri, that Roemer's work raised issues that were of relevance to Marx's analysis in Volume I of Capital. This modest assessment was not intended as a referendum on "Marx's general method and theoretical framework," nor as a defense of Roemer's general analytical method, despite Jim Devine's evident interest in enlarging the discussion to embrace these much larger issues. Nor were these larger questions engaged by my subsequent suggestion, in a response to Andrew K, that Veneziani's work, whatever its considerable merits, did not serve to "demolish" Roemer's contribution. Given these rather humble claims, I'm somewhat astonished that Jim took it upon himself to contact Roberto Veneziani concerning my comments on the latter's paper (noting that Jim has not been equally zealous in contacting Roemer to get his assessment of the much more extensive and negative critical comments that have been made here about his work, e.g.). It suggests to me that Jim might be taking this discussion way too seriously.
That said, though, I think Jim did a real service to PEN-L in enlisting Veneziani. I indicated my opinion of the quality of his theoretical work in an earlier post. Although I think it's unlikely to engage the interest of most listmembers, I look forward to discussing the set of issues raised by Roberto's paper. Since, as he notes in his recent post, his initial response (conveyed by Jim below) were made before he was aware of my full comments, I'll not address the remarks below, but instead respond directly to his separate posting.
