Kenneth M. Ehrenberg, University of Alabama, Department of Philosophy, and School of Law, has published Law's Artifactual Nature: How Legal Institutions Generate Normativity, in Reasons and Intentions in Law and Practical Agency 247-266 (George Pavlakos and Veronica Rodriguez-Blanco, eds.; Cambridge University Press, 2015). Here is the abstract.
I argue that law is best understood as an institutionalized abstract artifact.
