Jurisprudence is the philosophy and theory of law. It is concerned primarily with both what the law is and what it ought to be. That includes questions of how persons and social relations are understood in legal terms, and of the values in and of law. Work that is counted as jurisprudence is mostly philosophical, but it includes work that also belongs to other disciplines, such as sociology, history, politics and economics.
The Kellogg–Briand Pact or Pact of Paris – officially the General Treaty for Renunciation of War as an Instrument of National Policy – is a 1928 international agreement on peace in which signatory states promised not to use war to resolve "disputes or conflicts of whatever nature or of whatever origin they may be, which may arise among them". The pact was signed by Germany, France, and the United States on 27 August 1928, and by most other states soon after. Sponsored by France and the U.S., the Pact is named after its authors, United States Secretary of State Frank B. Kellogg and French foreign minister Aristide Briand. The pact was concluded outside the League of Nations and remains in effect.
Philosophy of law is a branch of philosophy that examines the nature of law and law's relationship to other systems of norms, especially ethics and political philosophy. It asks questions like "What is law?", "What are the criteria for legal validity?", and "What is the relationship between law and morality?" Philosophy of law and jurisprudence are often used interchangeably, though jurisprudence sometimes encompasses forms of reasoning that fit into economics or sociology.
Legal positivism is a school of thought of philosophy of law and jurisprudence which holds that law is constructed from social facts, without regards to the merits of such law. It was developed largely by legal philosophers during the 18th and 19th centuries, such as Jeremy Bentham and John Austin. While Bentham and Austin developed legal positivist theory, empiricism provided the theoretical basis for such developments to occur. Some of the most prominent legal positivist writers of the 20th century have been Hans Kelsen, H. L. A. Hart, and Joseph Raz.
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.
Lon Luvois Fuller was an American legal philosopher best known as a proponent of a secular and procedural form of natural law theory. Fuller was a professor of law at Harvard Law School for many years, and is noted in American law for his contributions to both jurisprudence and the law of contracts. His debate in 1958 with the prominent British legal philosopher H. L. A. Hart in the Harvard Law Review was important in framing the modern conflict between legal positivism and natural law theory. In his widely discussed 1964 book The Morality of Law, Fuller argues that all systems of law contain an "internal morality" that imposes on individuals a presumptive obligation of obedience. Robert S. Summers said in 1984: "Fuller was one of the four most important American legal theorists of the last hundred years".
Legality, in respect of an act, agreement, or contract is the state of being consistent with the law or of being lawful or unlawful in a given jurisdiction, and the construct of power.
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 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.

It called for a disarmament conference in 1925.

Analytical jurisprudence is a philosophical approach to law that draws on the resources of modern analytical philosophy to try to understand its nature. Since the boundaries of analytical philosophy are somewhat vague, it is difficult to say how far it extends. H. L. A. Hart was probably the most influential writer in the modern school of analytical jurisprudence, though its history goes back at least to Jeremy Bentham.
Jurisprudence of values or jurisprudence of principles is a school of legal philosophy. This school represents, according to some authors, a step in overcoming the contradictions of legal positivism and, for this reason, it has been considered by some authors as a post-positivism school. Jurisprudence of values is referred to in various works all over the world.

Law's Empire is a 1986 text in legal philosophy by Ronald Dworkin, in which the author continues his criticism of the philosophy of legal positivism as promoted by H.L.A. Hart during the middle to late 20th century. The book introduces Dworkin's Judge Hercules as an idealized version of a jurist with extraordinary legal skills who is able to challenge various predominating schools of legal interpretation and legal hermeneutics prominent throughout the 20th century. Judge Hercules is eventually challenged by Judge Hermes, another idealized version of a jurist who is affected by an affinity to respecting historical legal meaning arguments which do not affect Judge Hercules in the same manner. Judge Hermes' theory of legal interpretation is found by Dworkin in the end to be inferior to the approach of Judge Hercules.

Salmon Oliver Levinson was a practicing attorney who specialized in industrial organizations and corporate law. He was active in the peace movement in the 1920s and was responsible for drafting the Kellogg–Briand Pact, signed in 1928. Levinson noted: "We should have, not as now, laws of war, but laws against war; just as there are no laws of murder or of poisoning, but laws against them.” The treaty was the first international agreement to make war illegal. The treaty commits the parties to "condemn recourse to war for the solution of international controversies, and renounce it, as an instrument of national policy" and agree that all disputes should be settled peacefully.
A legal norm is a binding rule or principle, or norm, that organisations of sovereign power promulgate and enforce in order to regulate social relations. Legal norms determine the rights and duties of individuals who are the subjects of legal relations within the governing jurisdiction at a given point in time. Competent state authorities issue and publish basic aspects of legal norms through a collection of laws that individuals under that government must abide by, which is further guaranteed by state coercion. There are two categories of legal norms: normativity, which regulates the conduct of people, and generality, which is binding on an indefinite number of people and cases. Diplomatic and legislative immunity refers to instances where legal norms are constructed to be targeted towards a minority and are specifically only binding on them, such as soldiers and public officials.
