'What is law'
'The law is the public conscience.
It is not wisdom but authority that makes a law.'
The word law refers to limits upon various forms of behaviour. Some laws are descriptive they simply describe how people, or even, natural phenomena, usually behave. Other laws are prescriptive, describe how people should behave.
The relations between people are regulated by prescriptive law, in all societies. But most of them are reigned by customs, that is, informal rules of social and moral behaviour. But some of these rules we just accept if we take part of the particular groups where these laws are inserted, such as religious, educational groups. And some of them are precise laws done by nations and enforced to be accepted by all the citizens upon their powers.
Customs aren't made by the government, they don't need to be written down. These laws are taught by the instruction of family, school, the advice of friends and the experiences we acquire during our lives, learning, in this way how to behave in society. If we break these rules we wouldn't be punished by law authorities but society will criticise and ridicule us. They don't have anything to do with government laws.
The rules of social institutions tend to be more formal than the customs, carrying precise penalties for those who break them. The club has authority to ask the member to leave the club if a member breaks any rules.
When government make laws for the citizens, they use a system of courts backed by the power of the police to enforce these laws.
What motives do government have in making and enforcing laws? Social control is one of the answers. Public law establish the authority of the government itself, and civil laws provide the framework of interaction among citizens. Without laws, it is argued, there would be anarchy in society.
Another reason is the implementation of justice. Justice is a concept that most people think is very important. Sometimes a just decision is one that most people think is fair. For instance, when a man kill his wife because she's going through a painful illness and begging him to kill her. It seems unjust to find him guilty of such crime but if this mercy killing become so widespread that abuses will occur.
Justice delayed is justice denied.
Laws are sometimes simply an attempt to implement common sense. It's obvious to most people to dangerous driving should be punished; that fathers should provide financial support for their children if they desert their families; that a person should be compensated for losses when someone else breaks an agreement with him or her. But, in order to be enforced, common sense needs
to be defined in law, and when the definitions are being written, it becomes clear that common sense is not such a simple matter. Laws based on common sense don't necessarily look much like common sense when they have to be put into words.
The laws made by government for its country is different from the laws of other countries due to different life situations . So it's very difficult for someone to write an introductory book to law, since practices in this area are different varying from country to country, an important characteristic of the modern world.
The England and Wales legal system aren the oldest still operating in the modern world. English law has influenced the former English colonies Australia,India,Canada and United States, where the law play an important part in everyday life.
In short implementation of law is important for country's prosperity and better future.
