Jurisprudence, also known as the philosophy or theory of law, is a branch of law and philosophy that examines the positive and normative nature of law. It investigates issues such as the definition of law; legal validity; legal norms and values; as well as the relationship between law and other fields of study, including economics, ethics, history, sociology, and political philosophy.
In jurisprudence and legal philosophy, legal positivism is the theory that the existence of the law and its content depend on social facts, such as acts of legislation, judicial decisions, and customs, rather than on morality. This contrasts with natural law theory, which holds that law is necessarily connected to morality in such a way that any law that contradicts morality lacks legal validity.
Legal realism is a naturalistic approach to law; it is the view that jurisprudence should emulate the methods of natural science; that is, it should rely on empirical evidence. Hypotheses must be tested against observations of the world.
Ronald Myles Dworkin was an American legal philosopher, jurist, and scholar of United States constitutional law. At the time of his death, he was Frank Henry Sommer Professor of Law and Philosophy at New York University and Professor of Jurisprudence at University College London. Dworkin had taught previously at Yale Law School and the University of Oxford, where he was the Professor of Jurisprudence, successor to philosopher H. L. A. Hart.
Herbert Lionel Adolphus Hart was an English legal philosopher. One of the most influential legal theorists of the 20th century, he was instrumental in the development of the theory of legal positivism, which was popularised by his book, The Concept of Law. Hart's contributions focused on the nature of law, the relationship between law and morality, and the analysis of legal rules and systems, introducing concepts such as the "rule of recognition" that have shaped modern legal thought.
Pure Theory of Law is a book by jurist and legal theorist Hans Kelsen, first published in German in 1934 as Reine Rechtslehre, and in 1960 in a much revised and expanded edition. The latter was translated into English in 1967 as Pure Theory of Law. The title is the name of his general theory of law, Reine Rechtslehre.
The Concept of Law is a 1961 book by the legal philosopher H. L. A. Hart and his most famous work. The Concept of Law presents Hart's theory of legal positivism—the view that laws are rules made by humans and that there is no inherent or necessary connection between law and morality—within the framework of analytic philosophy. Hart sought to provide a theory of descriptive sociology and analytical jurisprudence. The book addresses a number of traditional jurisprudential topics such as the nature of law, whether laws are rules, and the relation between law and morality. Hart answers these by placing law into a social context while at the same time leaving the capability for rigorous analysis of legal terms, which in effect "awakened English jurisprudence from its comfortable slumbers".
Interpretivism is a school of thought in contemporary jurisprudence and the philosophy of law.

Riggs v. Palmer, 115 N.Y. 506 (1889), is an important New York state civil court case, in which the Court of Appeals of New York issued an 1889 opinion. Riggs was an example of the judiciary using the "social purpose" rule of statutory construction, the process of interpreting and applying legislation.
Leslie John Green is a Scottish-Canadian legal scholar specialising in jurisprudence. He is Professor of the Philosophy of Law and Fellow of Balliol College, Oxford University, and Professor of Law and Distinguished Faculty Fellow at Queen's University, Kingston. A legal positivist, his research also focuses on political philosophy and constitutional theory.
Conventionalism is the philosophical attitude that fundamental principles of a certain kind are grounded on agreements in society, rather than on external reality. Unspoken rules play a key role in the philosophy's structure. Although this attitude is commonly held with respect to the rules of grammar, its application to the propositions of ethics, law, science, biology, mathematics, and logic is more controversial.
Taking Rights Seriously is a 1977 book about the philosophy of law by the philosopher Ronald Dworkin. In the book, Dworkin argues against the dominant philosophy of Anglo-American legal positivism as presented by H. L. A. Hart in The Concept of Law (1961) and utilitarianism by proposing that rights of the individual against the state exist outside of the written law and function as "trumps" against the interests or wishes of the majority.
The Hart–Fuller debate is an exchange between the American law professor Lon L. Fuller and his English counterpart H. L. A. Hart, published in the Harvard Law Review in 1958 on morality and law, which demonstrated the divide between the positivist and natural law philosophy. Hart took the positivist view in arguing that morality and law were separate. Fuller's reply argued for morality as the source of law's binding power.
The Hart–Dworkin debate is a debate in legal philosophy between H. L. A. Hart and Ronald Dworkin. At the heart of the debate lies a Dworkinian critique of Hartian legal positivism, specifically, the theory presented in Hart's book The Concept of Law. While Hart insists that judges are within bounds to legislate on the basis of rules of law, Dworkin strives to show that in these cases, judges work from a set of "principles" which they use to formulate judgments, and that these principles either form the basis, or can be extrapolated from the present rules.

Experimental jurisprudence (X-Jur) is an emerging field of legal scholarship that explores the nature of legal phenomena through psychological investigations of legal concepts. The field departs from traditional analytic legal philosophy in its ambition to elucidate common intuitions in a systematic fashion employing the methods of social science. Equally, unlike research in legal psychology, X-Jur emphasises the philosophical implications of its findings, such as whether, how, and in what respects the law's content is a matter of moral perspective. Whereas some legal theorists have welcomed X-Jur's emergence, others have expressed reservations about the contributions it seeks to make.
