Legal Philosopher

Jurisprudence, also known as theory of law or philosophy of law, is the examination in a general perspective of what law is and what it ought to be. It investigates issues such as the definition of law; legal validity; legal norms and values; and the relationship between law and other fields of study, including economics, ethics, history, sociology, and political philosophy.

Modern jurisprudence began in the 18th century and was based on the first principles of natural law, civil law, and the law of nations. Contemporary philosophy of law 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. 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:

* Natural law holds that there are rational objective limits to the power of rulers, the foundations of law are accessible through reason, and it is from these laws of nature that human laws gain force.
* Analytic jurisprudence attempts to describe what law is. The two historically dominant theories in analytic jurisprudence are legal positivism and natural law theory. According to Legal Positivists, what law is and what law ought to be have no necessary connection to one another, so it is theoretically possible to engage in analytic jurisprudence without simultaneously engaging in normative jurisprudence. According to Natural Law Theorists, there is a necessary connection between what law is and what it ought to be, so it is impossible to engage in analytic jurisprudence without simultaniously engaging in normative jurisprudence.
* Normative jurisprudence attempts to prescribe what law ought to be. It is concerned with the goal or purpose of law and what moral or political theories provide a foundation for the law. It attempts to determine what the proper function of law should be, what sorts of acts should be subject to legal sanctions, and what sorts of punishment should be permitted.
* Sociological jurisprudence studies the nature and functions of law in the light of social scientific knowledge. It emphasises variation of legal phenomena between different cultures and societies. It relies especially on empirically-oriented social theory, but draws theoretical resources from diverse disciplines.
* Experimental jurisprudence seeks to investigate the content of legal concepts using the methods of social science, unlike the philosophical methods of traditional jurisprudence.
The terms "philosophy of law" and "jurisprudence" are often used interchangeably, though jurisprudence sometimes encompasses forms of reasoning that fit into economics or sociology.

Overview

Whereas lawyers are interested in what the law is on a specific issue in a specific jurisdiction, analytical philosophers of law are interested in identifying the features of law shared across cultures, times, and places. Taken together, these foundational features of law offer the kind of universal definition philosophers are after. The general approach allows philosophers to ask questions about, for example, what separates law from morality, politics, or practical reason. While the field has traditionally focused on giving an account of law's nature, some scholars have begun to examine the nature of domains within law, e.g. tort law, contract law, or criminal law. These scholars focus on what makes certain domains of law distinctive and how one domain differs from another. A particularly fecund area of research has been the distinction between tort law and criminal law, which more generally bears on the difference between civil and criminal law.

In addition to analytic jurisprudence, legal philosophy is also concerned with normative theories of law. "Normative jurisprudence involves normative, evaluative, and otherwise prescriptive questions about the law."

Etymology and terminology

The English word is derived from the Latin, . is the genitive form of meaning law, and meaning prudence (also: discretion, foresight, forethought, circumspection). 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 , which appeared earlier.

History

Ancient jurisprudence begins with various Dharmaśāstra texts of India. Dharmasutras of Āpastaṃba and Baudhāyana are examples.

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 offences, or in extraordinary situations, additions made to the ''edicta''. A ''iudex'' (originally a magistrate, later a private individual appointed to judge a specific case) 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 Justinian's was born.

Modern jurisprudence began in the 18th century and was based on the first principles of natural law, civil law, and the law of nations.

Natural law

Natural law holds that there are rational objective limits to the power of rulers, the foundations of law are accessible through reason, and it is from these laws of nature that human laws gain force. The moral theory of natural law asserts that law is inherent in nature and constitutive of morality, at least in part, and that an objective moral order, external to human legal systems, underlies natural law.
On this view, while legislators can enact and even successfully enforce immoral laws, such laws are ''legally'' invalid. The view is captured by the maxim: " an unjust law is no law at all", where 'unjust' means 'contrary to the natural law.' Natural law theory has medieval origins in the philosophy of Thomas Aquinas, especially in his ''Treatise on law''. In late 20th century, John Finnis revived interest in the theory and provided a modern reworking of it. For one, Finnis has argued that the maxim "an unjust law is no law at all" is a poor guide to the classical Thomist position.

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 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).
*''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.

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 (''dikaion physikon'', ''δικαίον φυσικόν'', Latin ''ius naturale''). 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''). Aquinas's influence was such as to affect a number of early translations of these passages, though more recent translations render them more literally.

Aristotle's 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.''Nicomachean Ethics'', Bk. V, ch. 3 When a person's 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 Aristotle's 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 one's 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. Aristotle's theoretical paternity of the natural law tradition is consequently disputed.

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 Theologiae''. One of the thirty-five Doctors of the Church, he is considered by many Catholics to be the Church's greatest theologian. Consequently, many institutions of learning have been named after him.

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

* Eternal law refers to divine reason, known only to God. It is God's plan for the universe. Man needs this plan, for without it he would totally lack direction.
*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 God's positive law for mankind
* Human law is supported by reason and enacted for the common good.

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.

School of Salamanca

Francisco de Vitoria was perhaps the first to develop a theory of ''ius gentium'' (law of nations), 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 Hugo Grotius, and argued for Vitoria and, later, Suárez's 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 Suárez, 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.

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.

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 theorist's 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.

Analytic jurisprudence

Unlike experimental jurisprudence, which investigates the content of legal concepts using the methods of social science, analytical jurisprudence seeks to provide a general account of the nature of law through the tools of conceptual analysis. The account is general in the sense of targeting universal features of law that hold at all times and places.

Analytic, or ''clarificatory'', jurisprudence takes a neutral point of view and uses descriptive language when referring to various aspects of legal systems. This was a philosophical development that rejected natural law's fusing of what law is and what it ought to be.See H L A Hart, 'Positivism and the Separation of Law and Morals' (1958) 71 ''Harv. L. Rev.'' 593 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.

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.

Sociological jurisprudence

An effort 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 (e.g. Ernst Fuchs, Hermann Kantorowicz, Eugen Ehrlich and François Gény) 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 Pound's lead or developed distinctive approaches to sociological jurisprudence. In Australia, Julius Stone strongly defended and developed Pound's 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. As an approach to jurisprudence, sociological jurisprudence uses the resources of social science to serve value-oriented juristic purposes. As such, it should be distinguished from sociology of law which as a field of social science has no necessary commitment to juristic aims.

Legal positivism

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

Legal positivism has traditionally been associated with three doctrines: the pedigree thesis, the separability thesis, and the discretion thesis. The pedigree thesis says that the right way to determine whether a directive is law is to look at the directive's source. The thesis claims that it is the fact that the directive was issued by the proper official within a legitimate government, for example, that determines the directive's legal validity—not the directive's moral or practical merits. The separability thesis states that law is conceptually distinct from morality. While law might contain morality, the separability thesis states that "it is in no sense a necessary truth that laws reproduce or satisfy certain demands of morality, though in fact they have often done so." Legal positivists disagree about the extent of the separability thesis. Exclusive legal positivists, notably Joseph Raz, go further than the standard thesis and deny that it is possible for morality to be a part of law at all. The discretion thesis states that judges create new law when they are given discretion to adjudicate cases where existing law underdetermines the result.

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 Hobbes's 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.

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 sovereign's 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. Bentham's 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. Austin's 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". H. L. A. Hart criticized Austin and Bentham's early legal positivism because the command theory failed to account for individual's compliance with the law.

Hans Kelsen

Hans Kelsen is considered one of the preeminent 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 ()—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.

H. L. A. Hart

In the English-speaking world, the most influential legal positivist of the twentieth century was H. L. A. 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 Kelsen's 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 of 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 is 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 , but do not necessarily, determine the legal validity of a norm.

Joseph Raz

Joseph Raz's theory of legal positivism argues against the incorporation of moral values to explain law's validity. In Raz's 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 law's 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. Raz claims it is a necessary truth that there are vices that a legal system cannot possibly have (for example, it cannot commit rape or murder).

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 Holmes's ''The Common Law'', he claims that " e life of the law has not been logic: it has been experience". This view was a reaction to legal formalism that was popular the time due to the Christopher Columbus Langdell. Holmes's writings on jurisprudence also laid the foundations for the predictive theory of law. In his article "The Path of the Law", Holmes argues that "the object of egalstudy...is 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 (other influences include Roscoe Pound, Karl Llewellyn, and Justice Benjamin Cardozo). 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 Hägerström, 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.

Critical legal studies

Critical legal studies are a new theory of jurisprudence that has developed since the 1970s. In 1977 a group of members of the Law and Society Association struck out on a new theoretical direction. The legal ideas of Peter Gabel, Morton Horwitz, Duncan Kennedy, Karl Klare, Mark Tushnet, and Roberto Unger have now found influence in many law schools. 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".Alan Hunt, "The Theory of Critical Legal Studies", Oxford Journal of Legal Studies, Vol. 6, No. 1 (1986): 1-45, esp. 1, 5. Se

DOI, 10.1093/ojls/6.1.1. 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. Roberto Mangabeira Unger and other authors in the movement contrast critical legal studies as a method, critical in approach, from the impersonal purposes and principles made necessary in legal reasoning such as formalism. He writes that it was "consequently also by rejecting judges as the chief addressees of legal analysis, and refusing to take the question—how should judges decide cases?—as the defining problem in jurisprudence." According to Unger the new American legal analysis will unlock the democratic potential of free societies in the same way earlier capitalistic economies benefited from the protection of private rights such as contracts and property.

Constitutionalism

Legal interpretivism

American legal philosopher Ronald Dworkin's legal theory attacks legal positivists that separate law's content from morality. In his book ''Law's 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 society's legal tradition. It follows from Dworkin's 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 Dworkin's view—in contrast with the views of legal positivists or legal realists—that in a society may know what its laws are, because no-one may know the best moral justification for its practices.

Interpretation, according to Dworkin's "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 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.

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.

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.

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.

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.

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 Bentham's 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.

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 Rawls's 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 constitutionalism, critical legal studies and libertarian theories of law.

Experimental jurisprudence

Experimental jurisprudence seeks to investigate the content of legal concepts using the methods of social science, unlike the philosophical methods of traditional jurisprudence.
