What Is Law?


Law is the system of rules that a particular country or community recognizes as regulating the actions of its members. It is often defined as a set of rules backed by the threat of sanctions that people must follow, and it has a wide variety of applications in society. For example, contract law defines the rights and duties of people when exchanging goods or services, while property law defines people’s rights and responsibilities toward tangible properties (e.g., houses and cars) and intangible assets (e.g., bank accounts and shares of stock).

The precise definition of law is a topic of longstanding debate. One common understanding is that it refers to a set of rules that are enforced by social or governmental institutions, and that this enforcement requires the use of force, typically by the police or military. Another view is that the term law covers a wider range of activities, including rules that are created and maintained by communities, such as local customs and social norms. Some philosophers have also analyzed the relationship between law and morality. For example, Jeremy Bentham’s utilitarian theory of law states that it is simply “commands, backed by the threat of sanctions, from a sovereign to whom people have a habit of obedience.” Others have taken a naturalistic approach, such as Jean-Jacques Rousseau, who believed that laws reflect the innate morality of humans.

For more information on the legal system, see criminal law; civil law; international law; family law; and labor law. Law is also used to refer to the professions of attorneys, judges, and other judicial officials.

Whether the term law is used to describe a specific rule or the broader system of laws in a country, it plays an important role in modern societies. It is a vital component of a well-run government and helps to maintain peace and order in a society. In addition to regulating commercial transactions, protecting the lives of citizens, and enforcing moral standards, it also serves the purpose of providing protections against fraud and ensuring that all parties are treated fairly. In the end, the success of any nation-state depends on its ability to maintain a strong and stable rule of law. A number of nations struggle to do this, leading to revolts against existing political-legal authority. In the most extreme cases, these rebellions may lead to a revolution in the form of a new government. In other instances, these revolutions simply lead to the aspiration for greater political-legal rights for citizens. In either case, the principle of equality under the law is a pillar of any democracy. The difference in the way that rich and poor citizens experience the law, however, is as measurable as the difference in the speed of light. This is because wealth and power distort the sense of fairness that the law provides. This distortion is an enduring problem, as it can undermine democratic principles and lead to the abuse of power by those with the greatest influence in society.
