In this reading Hume argues that utility is the sole origin and moral foundation of justice. His argument here follows from his contention that justice exists because of our limited benevolence in a world of limited scarcity. In this reading he argues that justice would not exist in those cases of over abundance, absolute scarcity, altruism, absence of benevolence, and self-sufficiency. He concludes that justice exists and is moral because of its utility.
This Reading is Taken From: An Enquiry Concerning the Principals of Morals, Section III Of Justice, Part 1
