At its most fundamental, a right is a claim, on other persons, that is acknowledged and reciprocated among the principals associated with that claim. The most basic of rights is a principle of interaction between people which amounts to the simplest version of the Golden Rule (do unto others as you would have them do unto you). In other words, it is a mutually beneficial agreement between two or more people; each of them agrees to behave in a certain way towards the others so that they will behave in the same way towards him/her.
Other than that, an entity (person or group) can make any sort of claim on other persons, but those claims remain simple assertions until the other persons acknowledge that claim as binding upon them. At that point, the claim becomes a privilege (a one-sided acknowledged claim). If all parties (including the originating claimant) also agree to reciprocate acknowledgement of such a claim, it becomes applicable to all, that is, applicable to everyone in the same sense and at the same time, and thus a right.
On that basis, additional structures [of social interaction] can be erected.
Legal rights
In jurisprudence and law, a right is the legal or moral entitlement to do or refrain from doing something or to obtain or refrain from obtaining an action, thing or recognition in civil society. Compare with privilege.
Generally speaking a right corresponds with a complementary obligation that others have on the same object or realm; for instance if someone has a right on a thing, simultaneously another party or parties have an obligation to do something (or to abstain from doing something) in order to respect that right or to give concrete execution to that right. Property rights provide a good example: society recognizes that individuals have title to particular property as defined by the transaction by which they acquired the property granting the individual free use and possession of the property. In many cases, especially regarding ideological and similar rights, the obligation depends on the legal system in its entirety, or on the state, or on the generical universality of other subjects submitted to the law.
The right can therefore be a faculty of doing something, of omitting or refusing to do something or of claiming something. Some interpretations express a typical form of right in the faculty of using something, and this is more often related to the right of property. The faculty (in all the above mentioned senses) can be originated by a (generical or specific) law, or by a private contract (which is sometimes exactly defined as a specific law between or among volunteer parties).
Other interpretations consider the right as a sort of freedom of something or as the object of justice. One of the definitions of justice is in fact the obligation that the legal system has toward the individual or toward the collectivity to grant respect or execution to his/her/its right, ordinarily with no need of explicit claim.
Rights can be divided into individual rights, that are held by citizens as individuals (or corporations) recognised by the legal system, and collective rights, held by an ensemble of citizens or a subgroup of citizens who have a certain characteristic in common. In some cases there can be an amount of tension between individual and collective rights.
With reference to the object of the right, a common general distinction is among:
intellectual rights, which include:
civil rights
religious rights
rights of opinion
real rights (from the Latin word “res”, thing), which include:
property rights
rights of use
liberties
See also: human rights, positive rights, negative rights, exclusive rights.
Particular systems can (or could in the past) include special rights like:
fief rights, which included:
economical rights (like the right to collect taxes)
performance rights (like the jus primae noctis or corvee)
