Hans Kelsen

Hans Kelsen was an influential legal philosopher known for his work on the nature of law and legal systems. He proposed the "Pure Theory of Law," which separates law from morality and politics, focusing purely on legal norms and their systematic structure. Kelsen argued that law is a set of rules that derives its authority from a basic norm, or "Grundnorm." His ideas emphasize that understanding law requires examining its internal logic and hierarchy, making significant contributions to legal positivism and the philosophy of constitutional law.
