Portico's Sheila Morrissey posted a valuable comment on the post that provided the background and sources for my CNI plenary. It set out the conventional wisdom against which I was arguing, but at such length that I felt it was inhibiting discussion. It was also difficult to respond to by adding a comment, among other reasons because there was no easy way to connect my responses to their targets in the comment. I therefore saved the text of Sheila's comment, deleted it from the original post, and reproduced it below the fold, together with my responses. Portico has posted a version of her comment here.
