Thanks MG for your informed comments. Someone correct me if I'm wrong, but if I am correct in believeing that the TAW were first published around 1985 or so, it might be assumed that he had been working on them since the 70s up to that point. I wonder if his ideas have evolved (or refined, or what you want to call it) since then, and maybe he might come to different conclusions based on scholarship of the last 30 years? I know I would disagree on some (okay, many) points with the "myself" of 20 tears ago.
