Law is a system of rules that societies and governments develop in order to regulate behavior and resolve disputes. It is a major topic of study in the fields of philosophy, social science and economic analysis. The precise definition of law is a subject of ongoing debate, but it is generally understood to include such concepts as the rule of reason, sanctity of human life, equality and fairness. The study of law is a rich source for scholarly inquiry and raises important questions concerning social justice.
The word law can also refer to a particular area of law, such as criminal or civil law. Alternatively, it can refer to the legal profession or the process of writing a law review article. A law review article is a work of scholarship written by a law student, usually during their second year of law school or their first year as members of a law journal. A law review article is intended to provide a scholarly perspective on a current issue or trend in law.
The most widely used definition of law is the one given by the Oxford English Dictionary, which defines it as “a system of rules ordained or enacted by some authority and enforced by sanctions”. However, a more precise explanation of law is found in the works of philosopher John Locke. His concept of law is based on the idea that each individual has a unique perception of reality, and that the laws imposed on society are simply an attempt to make all these perceptions of reality match up. This idea has been criticized, but it remains a core part of the theory of law.
Most modern legal systems are based on the concept of law as a set of rules that are binding on all persons. These rules are created and enforced by various means, including legislative statutes, executive orders and judicial decisions. In the US, for example, judges are bound by the principle of stare decisis, which is that a previous decision made by another court will have a binding effect on subsequent cases.
There are also some legal systems that are based on religious precepts. These include the Jewish Halakha, Islamic Sharia and Christian canon law. There are, however, few living cultures that rely on these types of legal systems.
The purpose of a legal system is to establish standards, maintain order, resolve disputes and protect liberty and rights. The exact scope of these functions varies between legal systems. For example, criminal law deals with behaviour that is considered harmful to social order and can lead to imprisonment. Civil law, on the other hand, deals with the resolution of lawsuits (disputes) between individuals or organizations. In addition to these areas, there are many sub-areas of law, such as international law, family law, immigration law, contract law and commercial law. Each of these areas has its own scholarly literature and methodologies.
