I have not generally tried to "do philosophy" on my blogs, though I have often linked to jurisprudential work by myself and others. But, as an experiment, I've created a new blog in which I'm going to work through some issues in legal philosophy. The posts will not be aimed at a generalist audience, but at specialists (students or scholars) in jurisprudence. The first substantive post discusses Brian Simpson's well-known paper on "The Common Law and Legal Theory." If writing up my thoughts or the comments on them proves instructive, I'll probably keep this up.
