I have just posted a detailed response to Timothy Sandefur's reply to my Independent Review critique of his article.

Unlike the briefer one I posted here because the Studies in Emergent Order site was being redesigned, I deal with his points in some depth.

I think the issues we are discussing are important for the intellectual development of the classical liberal tradition.
