The aim of my comment on William Twining's recent book Globalisation and Legal Scholarship (2011) is to present and contrast two models of general (or universal) jurisprudence: the one favoured by Twining and the other adopted by Jeremy Bentham. Twining's model aims to be general by capturing the great variety of laws as they exist in the world; by contrast, Bentham argued that it is mostly prescriptive claims about law that can be universal. I argue that the descriptive model suffers from serious flaws: it either has to posit arbitrary boundaries between law and non-law (this is the problem from which HLA Hart's version of descriptive jurisprudence suffers) or it does away with all boundaries, resulting in a shapeless barrage of data (this is the problem with Twining's version of this model). By contrast, I argue, the Benthamite version of general jurisprudence is free from these problems. I then argue that Twining's descriptive approach leads him to various prescriptive recommendations, which I believe are unattractive.
