Philosophy of law

Philosophy of law (or legal philosophy) is concerned with providing a general philosophical analysis of law and legal institutions. Issues in the field range from abstract conceptual questions about the nature of law and legal systems to normative questions about the relationship between law and morality and the justification for various legal institutions.

Topics in legal philosophy tend to be more abstract than related topics in political philosophy and applied ethics. For example, whereas the question of how properly to interpret the U.S. Constitution belongs to democratic theory (and hence falls under the heading of political philosophy), the analysis of legal interpretation falls under the heading of legal philosophy. Likewise, whereas the question of whether capital punishment is morally permissible falls under the heading of applied ethics, the question of whether the institution of punishment can be justified falls under the heading of legal philosophy.

There are roughly three categories into which the topics of legal philosophy fall: analytic jurisprudence, normative jurisprudence, and critical theories of law. Analytic jurisprudence involves providing an analysis of the essence of law so as to understand what differentiates it from other systems of norms, such as ethics. Normative jurisprudence involves the examination of normative, evaluative, and otherwise prescriptive issues about the law, such as restrictions on freedom, obligations to obey the law, and the grounds for punishment. Finally, critical theories of law, such as critical legal studies and feminist jurisprudence, challenge more traditional forms of legal philosophy.

Traditionally, philosophy of law proceeds by articulating and defending propositions about law that are general and abstract—i.e., that are true not of a specific legal system at a particular time (e.g., the United Kingdom in 1900) but of all legal systems in the present or perhaps of all laws at all times. Philosophy of law often aims to distinguish law from other systems of norms, such as morality (see ethics) or other social conventions. Views about the nature of law often depend upon, and occasionally have contributed to, answers to some of the most-fundamental philosophical questions—for example, regarding the foundations of morality, justice, and rights; the nature of human action and intention; the relations between social practices and values; the nature of knowledge and truth; and the justification of political rule (see political philosophy). The philosophy of law is therefore an integral part of philosophy more generally.
