I believe former Secretary Rumsfeld defined that as a "known unknown".
Besides, for those of us who don't actually believe in 'rights', which definition of 'rights' one wants to use doesn't really matter. The discussion will always come down to the same issues of existence and origin regardless. That is to say, if rights do exist, where did they come from?
With that definition, and the wonders of subjective relativism, you can define just about anything and everything as a 'right'. And so can everyone else on the planet.
I respectfully submit that is a non-functional definition.
As far as I'm concerned, the OP defines 'rights' as perfectly as they can or ever will be.
If electrons exist, where did they come from?
If we define rights in terms of political law, then rights have no legitimacy but force, for political law has no legitimacy but force.
We are dealing with what Edward Hall would call extension transference. Political law is an extension of the human mind. It is not based on reality other than the reality of the Human brain. However, in assigning reality to the extension, we are confusing the map for the mapped.
These are legal rights, and legal rights are arbitrary and capricious and depend on the whim of the political moment. They are a component of law, and law serves as the whore of faction. Faction is composed of shifting vectors. I really see no advantage to even address legal rights as other than privileges granted by the state. What the state gives, the state can take away.
Those who live in civilized states must face the reality of civilization. Civilizations rests on slavery, and law chains the slave. This would seem to be the fundamental nature of civilization, and you can alter this only by destroying civilization.
However, states are composed of individual Humans. In Humans, evolution, to use Hall’s terminology, is the evolution of extensions. Man is his culture, culture is limited by biology, but man is his culture. Cultural evolution in Civilized states is through war. Those states which lose, either perish or are exploited by the victors, and through exploitation lose their original identity.
As a consequence states are forced by necessity to conform to the requisites of war. This is not only on the battlefield but in the social order itself. Modern warfare depends on resources crafted within the social order and extensions developed to best produce and utilize these resources.
The state must therefor maximize its use of the Human component for military potency. This can only be done by shaping the social order in accordance with the demands of the nature of Man. If a state tries to force its human components into patterns in disagreement with the nature of Man, then it will suffer the consequences in impaired efficiency in meeting its military goals.
The name is not the named. Right is merely a word and words are but pointers to meaning. In this case, I am assigning the pointer to those societal requisites which are necessary for a Human to perform in accordance with his innate potential. They are based on the nature of Man and Mankind, and the Universe.
If a state ignores these requisites, it will pay the price. If it recognizes these requisites, it will advance its survival capacity in the evolutionary struggle.
This is competence, and the antithesis of competence is not evil, but incompetence.
