  However, also this richer understanding of concept possession, and the meatier picture of conceptual analysis it gives rise to, has been widely criticized (Marmor 2013, 215–217; Raz 2004, 10; Leiter 2007, 177–79). One question that immediately arises is which concept of law, exactly, constitutes the proper target of a theory of law. Is it the concept of law that is possessed by the legal practitioners in a particular jurisdiction? Or is it some universally shared concept of law? Worries loom either way. If a legal theory only aims to capture the concept of law employed in a particular jurisdiction, then that would render the theory parochial and it might lose its interest for those who are not concerned with that particular jurisdiction. On the other hand, one might doubt that there really is a universally shared concept of law that is employed by practitioners in all jurisdictions—or if there is one, it is doubtful that it is anything more than the sort of thin concept that one possesses in virtue of knowing what the word “law” in its juridical sense means.
