What is law?
1. The English word "law" means various forms of behavior. Some laws are descriptive: they simply describe how people, or even natural phenomena, usually behave. An example is the law of gravity; another is laws of economics. Other laws are prescriptive − they prescribe how people ought to behave. For example, the speed limits are laws that prescribe how fast we should drive.
2. In all societies, relations between people are regulated by prescriptive laws. Some of them are customs - that is informal rules of social and moral behavior. Some are rules we accept if we belong to particular social and cultural groups. And some are laws made by nations and enforced against all citizens.
3. Customs need not be made by governments, and they need not be written down. We learn how we are to behave in society through the instruction of family and teachers, the advice of friends, etc. Sometimes, we can break these rules without any penalty. But if we continually break the rules, other members of society may criticize us, or refuse to have anything to do with us. The rules of social instructions are more formal than customs, carrying penalties for those who break them. Sports clubs, for example, often have detailed rules for their members. But if a member breaks a rule and refuses to accept any punishment, the club may ask him or her to leave the club.
4. However, when governments make laws for their citizens, they use a system of courts and the police to enforce these laws. Of course, there may be instances where the law is not enforced against someone - such as when young children commit crimes, or when certain people are able to escape justice by using their money or influence.
