Abstract
Law centrally or archetypically is a moral idea, but not so much an ideal as a requirement of justice. Studying it contemplatively, as Simmonds's admirable Law as a Moral Idea does, tends to truncate the investigation of law's moral character and to obscure the extent to which jurisprudence can and should be a critical moral inquiry.
