The Concept of Law

H.L.A. Hart, a prominent 20th-century legal philosopher, developed a significant theory of law, primarily outlined in his influential book, The Concept of Law. Hart critiqued earlier "command theories" of law, such as those by Jeremy Bentham and John Austin, arguing they failed to account for laws that grant powers rather than simply command actions backed by punishment.12

Hart proposed that legal systems are formed by a combination of different types of norms. Central to his theory is the concept of a "rule of recognition," which is a social rule that officials within a legal system follow to identify valid laws. This rule specifies the criteria for legal validity, typically referencing sources like legislation or court decisions. Hart's positivism emphasizes the separability of law and morality, meaning laws do not need to be morally just to be considered valid.21
