Rights are legal, social, or ethical principles of freedom or entitlement; that is, rights are the fundamental normative rules about what is allowed of people or owed to people according to some legal system, social convention, or ethical theory. Rights are an important concept in law and ethics, especially theories of justice and deontology. The history of social conflicts has often involved attempts to define and redefine rights. According to the Stanford Encyclopedia of Philosophy, "rights structure the form of governments, the content of laws, and the shape of morality as it is currently perceived". Source: Wikipedia (en)
