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 of essential importance in such disciplines as 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".
Natural and legal rights
Natural rights are rights which are "natural" in the sense of "not artificial, not man-made", as in rights deriving from human nature or from the edicts of a god. They are universal; that is, they apply to all people, and do not derive from the laws of any specific society. They exist necessarily, inhere in every individual, and cannot be taken away. For example, it has been argued that humans have a natural right to life. These are sometimes called moral rights or inalienable rights.
Legal rights, in contrast, are based on a society's customs, laws, statutes or actions by legislatures. An example of a legal right is the right to vote of citizens. Citizenship, itself, is often considered as the basis for having legal rights, and has been defined as the "right to have rights". Legal rights are sometimes called civil rights or statutory rights and are culturally and politically relative since they depend on a specific societal context to have meaning.
Some thinkers see rights in only one sense while others accept that both senses have a measure of validity. There has been considerable philosophical debate about these senses throughout history. For example, Jeremy Bentham believed that legal rights were the essence of rights, and he denied the existence of natural rights; whereas Thomas Aquinas held that rights purported by positive law but not grounded in natural law were not properly rights at all, but only a facade or pretense of rights.
