This paper might be of interest to some readers; the abstract:

This essay examines Anglophone analytic legal philosophy in comparison to Professor Aldo Schiavello's account of Italian (and also, more broadly, non-Anglophone) analytic legal philosophy (in the same volume). The focus, in particular, is on legal positivism in H.L.A. Hart, Norberto Bobbio, and Alf Ross, and some of their striking shared commitments–especially, to methodological positivism (the idea that general jurisprudence can describe what the law is, without taking any position on what it ought to be). Methodological positivism is defended against a variety of objections raised by Schiavello.
