Jurisprudence or legal theory is the theoretical study of law. Scholars of jurisprudence seek to explain the nature of law in its most general form and provide a deeper understanding of legal reasoning, legal systems, legal institutions, and the role of law in society.

Modern jurisprudence began in the 18th century and was focused on the first principles of natural law, civil law, and the law of nations. General jurisprudence can be divided into categories both by the type of question scholars seek to answer and by the theories of jurisprudence, or schools of thought, regarding how those questions are best answered. Contemporary philosophy of law, which deals with general jurisprudence, addresses problems internal to law and legal systems and problems of law as a social institution that relates to the larger political and social context in which it exists.

This article addresses three distinct branches of thought in general jurisprudence. Ancient natural law is the idea that there are rational objective limits to the power of legislative rulers. The foundations of law are accessible through reason, and it is from these laws of nature that human laws gain whatever force they have. Analytic jurisprudence Clarificatory jurisprudence rejects natural laws fusing of what law is and what it ought to be. It espouses the use of a neutral point of view and descriptive language when referring to aspects of legal systems. It encompasses such theories of jurisprudence as "legal positivism", which holds that there is no necessary connection between law and morality and that the force of law comes from basic social facts; and "legal realism", which argues that the real-world practice of law determines what law is, the law having the force that it does because of what legislators, lawyers, and judges do with it. Normative jurisprudence is concerned with "evaluative" theories of law. It deals with what the goal or purpose of law is, or what moral or political theories provide a foundation for the law. It not only addresses the question "What is law?", but also tries to determine what the proper function of law should be, or what sorts of acts should be subject to legal sanctions, and what sorts of punishment should be permitted.


1. Etymology

The English word is derived from the Latin, iurisprudentia. Juris is the genitive form of jus meaning law, and prudentia meaning prudence. It refers to the exercise of good judgment, common sense, and caution, especially in the conduct of practical matters. The word first appeared in written English in 1628, at a time when the word prudence meant knowledge of, or skill in, a matter. It may have entered English via the French jurisprudence, which appeared earlier.


2. History

Ancient Indian jurisprudence is mentioned in various Dharmasāstra texts, starting with the Dharmasutra of Bhodhayana.

In Ancient China, the Daoists, Confucians, and Legalists all had competing theories of jurisprudence.

Jurisprudence in Ancient Rome had its origins with the periti - experts in the jus mos maiorum traditional law, a body of oral laws and customs.

Praetors established a working body of laws by judging whether or not singular cases were capable of being prosecuted either by the edicta, the annual pronunciation of prosecutable offense, or in extraordinary situations, additions made to the edicta. An iudex would then prescribe a remedy according to the facts of the case.

The sentences of the iudex were supposed to be simple interpretations of the traditional customs, but - apart from considering what traditional customs applied in each case - soon developed a more equitable interpretation, coherently adapting the law to newer social exigencies. The law was then adjusted with evolving institutiones legal concepts, while remaining in the traditional mode. Praetors were replaced in the 3rd century BC by a laical body of prudentes. Admission to this body was conditional upon proof of competence or experience.

Under the Roman Empire, schools of law were created, and practice of the law became more academic. From the early Roman Empire to the 3rd century, a relevant body of literature was produced by groups of scholars, including the Proculians and Sabinians. The scientific nature of the studies was unprecedented in ancient times.

After the 3rd century, juris prudentia became a more bureaucratic activity, with few notable authors. It was during the Eastern Roman Empire 5th century that legal studies were once again undertaken in depth, and it is from this cultural movement that Justinians Corpus Juris Civilis was born.


3. Natural law

In its general sense, natural law theory may be compared to both state-of-nature law and general law understood on the basis of being analogous to the laws of physical science. Natural law is often contrasted to positive law which asserts law as the product of human activity and human volition.

Another approach to natural-law jurisprudence generally asserts that human law must be in response to compelling reasons for action. There are two readings of the natural-law jurisprudential stance.

  • The weak natural law thesis holds that if a human law fails to be in response to compelling reasons, then it can still be called a "law", but it must be recognised as a defective law.
  • The strong natural law thesis holds that if a human law fails to be in response to compelling reasons, then it is not properly a "law" at all. This is captured, imperfectly, in the famous maxim: lex iniusta non est lex an unjust law is no law at all.

Notions of an objective moral order, external to human legal systems, underlie natural law. What is right or wrong can vary according to the interests one is focused on. John Finnis, one of the most important of modern natural lawyers, has argued that the maxim "an unjust law is no law at all" is a poor guide to the classical Thomist position.

Strongly related to theories of natural law are classical theories of justice, beginning in the West with Platos Republic.


3.1. Natural law Aristotle

Aristotle is often said to be the father of natural law. Like his philosophical forefathers Socrates and Plato, Aristotle posited the existence of natural justice or natural right. His association with natural law is largely due to how he was interpreted by Thomas Aquinas. This was based on Aquinas conflation of natural law and natural right, the latter of which Aristotle posits in Book V of the Nicomachean Ethics Book IV of the Eudemian Ethics. Aquinass influence was such as to affect a number of early translations of these passages, though more recent translations render them more literally.

Aristotles theory of justice is bound up in his idea of the golden mean. Indeed, his treatment of what he calls "political justice" derives from his discussion of "the just" as a moral virtue derived as the mean between opposing vices, just like every other virtue he describes. His longest discussion of his theory of justice occurs in Nicomachean Ethics and begins by asking what sort of mean a just act is. He argues that the term "justice" actually refers to two different but related ideas: general justice and particular justice. When a persons actions toward others are completely virtuous in all matters, Aristotle calls them "just" in the sense of "general justice"; as such, this idea of justice is more or less coextensive with virtue. "Particular" or "partial justice", by contrast, is the part of "general justice" or the individual virtue that is concerned with treating others equitably.

Aristotle moves from this unqualified discussion of justice to a qualified view of political justice, by which he means something close to the subject of modern jurisprudence. Of political justice, Aristotle argues that it is partly derived from nature and partly a matter of convention. This can be taken as a statement that is similar to the views of modern natural law theorists. But it must also be remembered that Aristotle is describing a view of morality, not a system of law, and therefore his remarks as to nature are about the grounding of the morality enacted as law, not the laws themselves.

The best evidence of Aristotles having thought there was a natural law comes from the Rhetoric, where Aristotle notes that, aside from the "particular" laws that each people has set up for itself, there is a "common" law that is according to nature. The context of this remark, however, suggests only that Aristotle thought that it could be rhetorically advantageous to appeal to such a law, especially when the "particular" law of ones own city was adverse to the case being made, not that there actually was such a law. Aristotle, moreover, considered certain candidates for a universally valid, natural law to be wrong. Aristotles theoretical paternity of the natural law tradition is consequently disputed.


3.2. Natural law Thomas Aquinas

Thomas Aquinas is the foremost classical proponent of natural theology, and the father of the Thomistic school of philosophy, for a long time the primary philosophical approach of the Roman Catholic Church. The work for which he is best known is the Summa Theologica. One of the thirty-five Doctors of the Church, he is considered by many Catholics to be the Churchs greatest theologian. Consequently, many institutions of learning have been named after him.

Aquinas distinguished four kinds of law: eternal, natural, divine, and human:

  • Natural law is the "participation" in the eternal law by rational human creatures, and is discovered by reason
  • Divine law is revealed in the scriptures and is Gods positive law for mankind
  • Human law is supported by reason and enacted for the common good.
  • Eternal law refers to divine reason, known only to God. It is Gods plan for the universe. Man needs this plan, for without it he would totally lack direction.

Natural law is based on "first principles":

. this is the first precept of the law, that good is to be done and promoted, and evil is to be avoided. All other precepts of the natural law are based on this.

The desires to live and to procreate are counted by Aquinas among those basic natural human values on which all other human values are based.


3.3. Natural law School of Salamanca

Francisco de Vitoria was perhaps the first to develop a theory of ius gentium the rights of peoples, and thus is an important figure in the transition to modernity. He extrapolated his ideas of legitimate sovereign power to international affairs, concluding that such affairs ought to be determined by forms respecting of the rights of all and that the common good of the world should take precedence before the good of any single state. This meant that relations between states ought to pass from being justified by force to being justified by law and justice. Some scholars have upset the standard account of the origins of International law, which emphasises the seminal text De iure belli ac pacis by Grotius, and argued for Vitoria and, later, Suarezs importance as forerunners and, potentially, founders of the field. Others, such as Koskenniemi, have argued that none of these humanist and scholastic thinkers can be understood to have founded international law in the modern sense, instead placing its origins in the post-1870 period.

Francisco Suarez, regarded as among the greatest scholastics after Aquinas, subdivided the concept of ius gentium. Working with already well-formed categories, he carefully distinguished ius inter gentes from ius intra gentes. Ius inter gentes which corresponds to modern international law was something common to the majority of countries, although, being positive law, not natural law, it was not necessarily universal. On the other hand, ius intra gentes, or civil law, is specific to each nation.


3.4. Natural law Lon Fuller

Writing after World War II, Lon L. Fuller defended a secular and procedural form of natural law. He emphasised that the natural law must meet certain formal requirements such as being impartial and publicly knowable. To the extent that an institutional system of social control falls short of these requirements, Fuller argued, we are less inclined to recognise it as a system of law, or to give it our respect. Thus, the law must have a morality that goes beyond the societal rules under which laws are made.


3.5. Natural law John Finnis

Sophisticated positivist and natural law theories sometimes resemble each other and may have certain points in common. Identifying a particular theorist as a positivist or a natural law theorist sometimes involves matters of emphasis and degree, and the particular influences on the theorists work. The natural law theorists of the distant past, such as Aquinas and John Locke made no distinction between analytic and normative jurisprudence, while modern natural law theorists, such as John Finnis, who claim to be positivists, still argue that law is moral by nature. In his book Natural Law and Natural Rights 1980, 2011, John Finnis provides a restatement of natural law doctrine.


4. Analytic jurisprudence

Analytic, or "clarificatory", jurisprudence means taking a neutral point of view and using descriptive language when referring to various aspects of legal systems. This was a philosophical development that rejected natural laws fusing of what law is and what it ought to be. David Hume argued, in A Treatise of Human Nature, that people invariably slip from describing what the world is to asserting that we therefore ought to follow a particular course of action. But as a matter of pure logic, one cannot conclude that we ought to do something merely because something is the case. So analysing and clarifying the way the world is must be treated as a strictly separate question from normative and evaluative questions of what ought to be done.

The most important questions of analytic jurisprudence are: "What are laws?"; "What is the law?"; "What is the relationship between law and power/sociology?"; and "What is the relationship between law and morality?" Legal positivism is the dominant theory, although there is a growing number of critics who offer their own interpretations.


4.1. Analytic jurisprudence Historical school

Historical jurisprudence came to prominence during the debate on the proposed codification of German law. In his book On the Vocation of Our Age for Legislation and Jurisprudence, Friedrich Carl von Savigny argued that Germany did not have a legal language that would support codification because the traditions, customs, and beliefs of the German people did not include a belief in a code. Historicists believe that law originates with society.


4.2. Analytic jurisprudence Sociological jurisprudence

An effort to systematically to inform jurisprudence from sociological insights developed from the beginning of the twentieth century, as sociology began to establish itself as a distinct social science, especially in the United States and in continental Europe. In Germany, Austria and France, the work of the "free law" theorists encouraged the use of sociological insights in the development of legal and juristic theory. The most internationally influential advocacy for a "sociological jurisprudence" occurred in the United States, where, throughout the first half of the twentieth century, Roscoe Pound, for many years the Dean of Harvard Law School, used this term to characterise his legal philosophy. In the United States, many later writers followed Pounds lead or developed distinctive approaches to sociological jurisprudence. In Australia, Julius Stone strongly defended and developed Pounds ideas. In the 1930s, a significant split between the sociological jurists and the American legal realists emerged. In the second half of the twentieth century, sociological jurisprudence as a distinct movement declined as jurisprudence came more strongly under the influence of analytical legal philosophy; but with increasing criticism of dominant orientations of legal philosophy in English-speaking countries in the present century, it has attracted renewed interest. Increasingly, its contemporary focus is on providing theoretical resources for jurists to aid their understanding of new types of regulation for example, the diverse kinds of developing transnational law and the increasingly important interrelations of law and culture, especially in multicultural Western societies.


4.3. Analytic jurisprudence Legal positivism

Legal positivism is the view that the content of law is dependent on social facts and that a legal systems existence is not constrained by morality. Within legal positivism, theorists agree that laws content is a product of social facts, but theorists disagree whether laws validity can be explained by incorporating moral values. Legal positivists who argue against the incorporation of moral values to explain laws validity are labeled exclusive or hard legal positivists. Joseph Razs legal positivism is an example of exclusive legal positivism. Legal positivists who argue that laws validity can be explained by incorporating moral values are labeled inclusive or soft legal positivists. The legal positivist theories of HLA Hart and Jules Coleman are examples of inclusive legal positivism.


4.4. Analytic jurisprudence Thomas Hobbes

Hobbes was a social contractarian and believed that the law had peoples tacit consent. He believed that society was formed from a state of nature to protect people from the state of war that would exist otherwise. In Leviathan, Hobbes argues that without an ordered society life would be "solitary, poor, nasty, brutish and short." It is commonly said that Hobbess views on human nature were influenced by his times. The English Civil War and the Cromwellian dictatorship had taken place; and, in reacting to that, Hobbes felt that absolute authority vested in a monarch, whose subjects obeyed the law, was the basis of a civilized society.


4.5. Analytic jurisprudence Bentham and Austin

John Austin and Jeremy Bentham were early legal positivists who sought to provide a descriptive account of law that describes the law as it is. Austin explained the descriptive focus for legal positivism by saying, "The existence of law is one thing; its merit and demerit another. Whether it be or be not is one enquiry; whether it be or be not conformable to an assumed standard, is a different enquiry." For Austin and Bentham, a society is governed by a sovereign who has de facto authority. Through the sovereigns authority come laws, which for Austin and Bentham are commands backed by sanctions for non-compliance. Along with Hume, Bentham was an early and staunch supporter of the utilitarian concept, and was an avid prison reformer, advocate for democracy, and firm atheist. Benthams views about law and jurisprudence were popularized by his student John Austin. Austin was the first chair of law at the new University of London, from 1829. Austins utilitarian answer to "what is law?" was that law is "commands, backed by threat of sanctions, from a sovereign, to whom people have a habit of obedience". HLA Hart criticized Austin and Benthams early legal positivism because the command theory failed to account for individuals compliance with the law.


4.6. Analytic jurisprudence Hans Kelsen

Hans Kelsen is considered one of the prominent jurists of the 20th century and has been highly influential in Europe and Latin America, although less so in common-law countries. His Pure Theory of Law describes law as "binding norms", while at the same time refusing to evaluate those norms. That is, "legal science" is to be separated from "legal politics". Central to the Pure Theory of Law is the notion of a "basic norm" Grundnorm - a hypothetical norm, presupposed by the jurist, from which all "lower" norms in the hierarchy of a legal system, beginning with constitutional law, are understood to derive their authority or the extent to which they are binding. Kelsen contends that the extent to which legal norms are binding, their specifically "legal" character, can be understood without tracing it ultimately to some suprahuman source such as God, personified Nature or - of great importance in his time - a personified State or Nation.


4.7. Analytic jurisprudence HLA Hart

In the English-speaking world, the most influential legal positivist of the twentieth century was HLA Hart, professor of jurisprudence at Oxford University. Hart argued that the law should be understood as a system of social rules. In The Concept of Law, Hart rejected Kelsens views that sanctions were essential to law and that a normative social phenomenon, like law, cannot be grounded in non-normative social facts.

Hart claimed that law is the union primary rules and secondary rules. Primary rules require individuals to act or not act in certain ways and create duties for the governed to obey. Secondary rules are rules that confer authority to create new primary rules or modify existing ones. Secondary rules are divided into rules of adjudication how to resolve legal disputes, rules of change how laws are amended, and the rule of recognition how laws are identified as valid. The validity of a legal system comes from the "rule of recognition," which is a customary practice of officials especially barristers and judges who identify certain acts and decisions as sources of law. In 1981, Neil MacCormick wrote a pivotal book on Hart second edition published in 2008, which further refined and offered some important criticisms that led MacCormick to develop his own theory the best example of which his Institutions of Law, 2007. Other important critiques include those of Ronald Dworkin, John Finnis, and Joseph Raz.

In recent years, debates on the nature of law have become increasingly fine-grained. One important debate is within legal positivism. One school is sometimes called "exclusive legal positivism" and is associated with the view that the legal validity of a norm can never depend on its moral correctness. A second school is labeled "inclusive legal positivism", a major proponent of which is Wil Waluchow, and is associated with the view that moral considerations may, but do not necessarily, determine the legal validity of a norm.


4.8. Analytic jurisprudence Joseph Raz

Joseph Razs theory of legal positivism argues against the incorporation of moral values to explain laws validity. In Razs 1979 book The Authority of Law, he criticised what he called the "weak social thesis" to explain law. He formulates the weak social thesis as "a Sometimes the identification of some laws turn on moral arguments, but also with, b In all legal systems the identification of some law turns on moral argument." Raz argues that laws authority is identifiable purely through social sources, without reference to moral reasoning. This view he calls "the sources thesis." Raz suggests that any categorisation of rules beyond their role as authority is better left to sociology than to jurisprudence. Some philosophers used to contend that positivism was the theory that held that there was "no necessary connection" between law and morality; but influential contemporary positivists - including Joseph Raz, John Gardner, and Leslie Green - reject that view. As Raz points out, it is a necessary truth that there are vices that a legal system cannot possibly have for example, it cannot commit rape or murder.


4.9. Analytic jurisprudence Legal realism

Legal realism is the view that a theory of law should be descriptive and account for the reasons why judges decide cases as they do. Legal realism had some affinities with the sociology of law and sociological jurisprudence. The essential tenet of legal realism is that all law is made by humans and thus should account for reasons besides legal rules that led to a legal decision.

There are two separate schools of legal realism: American legal realism and Scandinavian legal realism. American legal realism grew out of the writings of Oliver Wendell Holmes. At the start of Holmess The Common Law, he claims that" prediction, the prediction of the incidence of the public force through the instrumentality of the courts."

For the American legal realists of the early twentieth century, legal realism sought to describe the way judges decide cases. For legal realists such as Jerome Frank, judges start with the facts before them and then move to legal principles. Before legal realism, theories of jurisprudence turned this method around where judges were thought to begin with legal principles and then look to facts.

It has become common today to identify Justice Oliver Wendell Holmes, Jr., as the main precursor of American Legal Realism. Karl Llewellyn, another founder of the U.S. legal realism movement, similarly believed that the law is little more than putty in the hands of judges who are able to shape the outcome of cases based on their personal values or policy choices.

The Scandinavian school of legal realism argued that law can be explained through the empirical methods used by social scientists. Prominent Scandinavian legal realists are Alf Ross, Axel Hagerstrom, and Karl Olivecrona. Scandinavian legal realists also took a naturalist approach to law.

Despite its decline in popularity, legal realism continues to influence a wide spectrum of jurisprudential schools today, including critical legal studies, feminist legal theory, critical race theory, sociology of law, and law and economics.


4.10. Analytic jurisprudence Critical legal studies

Critical legal studies are a new theory of jurisprudence that has developed since the 1970s. The theory can generally be traced to American legal realism and is considered "the first movement in legal theory and legal scholarship in the United States to have espoused a committed Left political stance and perspective". It holds that the law is largely contradictory, and can be best analyzed as an expression of the policy goals of a dominant social group.


4.11. Analytic jurisprudence Critical rationalism

Karl Popper originated the theory of critical rationalism. According to Reinhold Zippelius many advances in law and jurisprudence take place by operations of critical rationalism. He writes, "daS die Suche nach dem Begriff des Rechts, nach seinen Bezugen zur Wirklichkeit und nach der Gerechtigkeit experimentierend voranschreitet, indem wir Problemlosungen versuchsweise entwerfen, uberprufen und verbessern".


4.12. Analytic jurisprudence Legal interpretivism

American legal philosopher Ronald Dworkins legal theory attacks legal positivists that separate laws content from morality. In his book Laws Empire, Dworkin argued that law is an "interpretive" concept that requires barristers to find the best-fitting and most just solution to a legal dispute, given their constitutional traditions. According to him, law is not entirely based on social facts, but includes the best moral justification for the institutional facts and practices that form a societys legal tradition. It follows from Dworkins view that one cannot know whether a society has a legal system in force, or what any of its laws are, until one knows some truths about the moral justifications of the social and political practices of that society. It is consistent with Dworkins view - in contrast with the views of legal positivists or legal realists - that no-one in a society may know what its laws are, because no-one may know the best moral justification for its practices.

Interpretation, according to Dworkins "integrity theory of law", has two dimensions. To count as an interpretation, the reading of a text must meet the criterion of "fit". Of those interpretations that fit, however, Dworkin maintains that the correct interpretation is the one that portrays the practices of the community in their best light, or makes them "the best that they can be". But many writers have doubted whether there is a single best moral justification for the complex practices of any given community, and others have doubted whether, even if there is, it should be counted as part of the law of that community.


4.13. Analytic jurisprudence Therapeutic jurisprudence

Consequences of the operation of legal rules or legal procedures - or of the behavior of legal actors such as lawyers and judges - may be either beneficial therapeutic or harmful anti-therapeutic to people. Therapeutic jurisprudence "TJ" studies law as a social force or agent and uses social science methods and data to study the extent to which a legal rule or practice affects the psychological well-being of the people it impacts.


5. Normative jurisprudence

In addition to the question, "What is law?", legal philosophy is also concerned with normative, or "evaluative" theories of law. What is the goal or purpose of law? What moral or political theories provide a foundation for the law? What is the proper function of law? What sorts of acts should be subject to punishment, and what sorts of punishment should be permitted? What is justice? What rights do we have? Is there a duty to obey the law? What value has the rule of law? Some of the different schools and leading thinkers are discussed below.


5.1. Normative jurisprudence Virtue jurisprudence

Aretaic moral theories, such as contemporary virtue ethics, emphasize the role of character in morality. Virtue jurisprudence is the view that the laws should promote the development of virtuous character in citizens. Historically, this approach has been mainly associated with Aristotle or Thomas Aquinas. Contemporary virtue jurisprudence is inspired by philosophical work on virtue ethics.


5.2. Normative jurisprudence Deontology

Deontology is the "theory of duty or moral obligation". The philosopher Immanuel Kant formulated one influential deontological theory of law. He argued that any rule we follow must be able to be universally applied, i.e. we must be willing for everyone to follow that rule. A contemporary deontological approach can be found in the work of the legal philosopher Ronald Dworkin.


5.3. Normative jurisprudence Utilitarianism

Utilitarianism is the view that the laws should be crafted so as to produce the best consequences for the greatest number of people. Historically, utilitarian thinking about law has been associated with the philosopher Jeremy Bentham. John Stuart Mill was a pupil of Benthams and was the torch bearer for utilitarian philosophy throughout the late nineteenth century. In contemporary legal theory, the utilitarian approach is frequently championed by scholars who work in the law and economics tradition.


5.4. Normative jurisprudence John Rawls

John Rawls was an American philosopher; a professor of political philosophy at Harvard University; and author of A Theory of Justice 1971, Political Liberalism, Justice as Fairness: A Restatement, and The Law of Peoples. He is widely considered one of the most important English-language political philosophers of the 20th century. His theory of justice uses a method called "original position" to ask us which principles of justice we would choose to regulate the basic institutions of our society if we were behind a "veil of ignorance". Imagine we do not know who we are - our race, sex, wealth, status, class, or any distinguishing feature - so that we would not be biased in our own favour. Rawls argued from this "original position" that we would choose exactly the same political liberties for everyone, like freedom of speech, the right to vote, and so on. Also, we would choose a system where there is only inequality because that produces incentives enough for the economic well-being of all society, especially the poorest. This is Rawlss famous "difference principle". Justice is fairness, in the sense that the fairness of the original position of choice guarantees the fairness of the principles chosen in that position.

There are many other normative approaches to the philosophy of law, including critical legal studies and libertarian theories of law.
