Jurisprudence is known as the philosophy of law which delves into the theoretical foundations of law and legal systems. It examines the nature, purposes, sources, and validity of laws, seeking to answer fundamental questions such as: What is law? What constitutes a legal system? How does law relate to morality and society? The jurisprudence provides an in depth understanding of how laws operate and their impact on society.

Definitions of Famous Jurists

The definitions provided by famous jurists about jurisprudence establish different interpretations regarding law as well as its nature and function and application and thus influence legal understanding and interpretation. Further below you will find selected explanations about the following definitions.

• John Austin: Defined law as "the command of the sovereign backed by sanction." According to him laws are directives issued by a sovereign authority, enforced through the threat of penalties.
• H.L.A. Hart: Critiquing Austin's command theory, Hart introduced the concept of law as a system of rules, differentiating between primary rules (obligations) and secondary rules (rules about rules). He emphasized the "internal point of view," where members of a society accept and follow rules not merely out of fear of sanctions but because they see them as standards to guide their behavior.
• Hans Kelsen: Proposed the "Pure Theory of Law," asserting that law is a normative science distinct from morality and other social sciences. He introduced the idea of a "Grundnorm" or basic norm, which serves as the foundational premise upon which a legal system is built.
• Ronald Dworkin: His criticism addressed legal positivism by showing the existence of principles along with law's rule structure. According to Hart he believed judges should bring both moral principles and rights into law interpretation since law and morality exist as interconnected elements.

The key concepts of jurisprudence include fundamental legal theories and doctrines that define law, its sources, interpretation, and role in society and justice. Some of them are as under-

Schools under Jurisprudence Notes

Some of the important schools of jurisprudence are as under-

Conclusion

Jurisprudence is the foundation of legal theory which provides a philosophical and analytical structure to understand the nature, purpose and function of law. By exploring different schools of thought-Natural Law, Legal Positivism, Legal Realism, and Critical Legal Studies- jurisprudence helps in shaping legal reasoning and judicial interpretation.

The development of jurisprudence is characterised by landmark judgments which redefine various legal principles and constitutional interpretations. The legal doctrines such as Stare Decisis, Ratio Decidendi, and the Rule of Law, jurisprudence ensures consistency and stability in legal systems.

The study of jurisprudence becomes crucial for future judges and scholars because it instructs them about critical analysis together with analytical methods alongside societal role understanding for law. Students together with professionals can understand the relationship between law and morality along with politics and social transformation by actively studying vital questions and legal cases.

Jurisprudence functions as a fundamental tool to analyze both the current legal definition and the proper legal direction that should exist.
