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 law's 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. The English word is derived from the Latin, iurisprudentia. Juris is the genitive form of jus meaning law, and prudentia means 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 jurisprudence, which appeared earlier. Ancient Indian jurisprudence is mentioned in various Dharmaśāstra 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.
