The branch of philosophy that asks what law is and how it functions as a normative institution, rather than addressing specific legal questions bound to one jurisdiction. Its foundational question, simply, is what is law, and it presupposes that law has identifiable characteristics that philosophical analysis can uncover. A central dispute divides legal positivists, who hold that legal validity depends on social facts alone, from natural law theorists, who hold that a norm's moral content partly determines whether it counts as law at all.

Facts
Central Question
What is law, and what, if anything, is the relationship between law and morality? 1
Key Debate
Legal positivism against natural law theory: whether the grounds of legality are exclusively social facts, such as legislation and custom, as positivists argue, or partly moral in nature, so that a sufficiently unjust rule fails to count as law at all, as natural law theorists argue. The Stanford Encyclopedia of Philosophy notes that the claim that the moral content of norms partly determines their legality has been fiercely challenged by the legal positivism tradition. 1
Disputed
Key Debate
Whether there is a moral duty to obey an unjust law: legal positivists such as H.L.A. Hart separate a law's validity from its morality and treat obedience as a further question, while natural law theorists hold that a sufficiently unjust rule fails to bind in conscience at all. 2
Debates over civil disobedience, from Thoreau through the twentieth century civil rights movement, kept this question live outside the seminar room as well as inside it.
