Rights - whether moral or legal - impose obligations or duties on third parties towards the right-holder. One has a right AGAINST other people and thus can prescribe to them certain obligatory behaviors and proscribe certain acts or omissions. Rights and duties are two sides of the same Janus-like ethical coin.
This duality confuses people. They often erroneously identify rights with their attendant duties or obligations, with the morally decent, or even with the morally permissible. One's rights inform other people how they MUST behave towards one - not how they SHOULD or OUGHT to act morally. Moral behavior is not dependent on the existence of a right. Obligations are.
To complicate matters further, many apparently simple and straightforward rights are amalgams of more basic moral or legal principles. To treat such rights as unities is to mistreat them.
Take the right to life. It is a compendium of no less than eight distinct rights: the right to be brought to life, the right to be born, the right to have one's life maintained, the right not to be killed, the right to have one's life saved, the right to save one's life (wrongly reduced to the right to self-defense), the right to terminate one's life, and the right to have one's life terminated.
None of these rights is self-evident, or unambiguous, or universal, or immutable, or automatically applicable. It is safe to say, therefore, that these rights are not primary as hitherto believed - but derivative.
The Right to be Brought to Life
In most moral systems - including all major religions and Western legal methodologies - it is life that gives rise to rights. The dead have rights only because of the existence of the living. Where there is no life - there are no rights. Stones have no rights (though many animists would find this statement abhorrent).
Hence the vitriolic debate about cloning which involves denuding an unfertilized egg of its nucleus. Is there life in an egg or a sperm cell?
That something exists, does not necessarily imply that it harbors life. Sand exists and it is inanimate. But what about things that exist and have the potential to develop life? No one disputes the existence of eggs and sperms - or their capacity to grow alive.
Is the potential to be alive a legitimate source of rights? Does the egg have any rights, or, at the very least, the right to be brought to life (the right to become or to be) and thus to acquire rights? The much trumpeted right to acquire life pertains to an entity which exists but is not alive - an egg. It is, therefore, an unprecedented kind of right. Had such a right existed, it would have implied an obligation or duty to give life to the unborn and the not yet conceived.
Clearly, life manifests, at the earliest, when an egg and a sperm unite at the moment of fertilization. Life is not a potential - it is a process triggered by an event. An unfertilized egg is neither a process - nor an event. It does not even possess the potential to become alive unless and until it is fertilized.
The potential to become alive is not the ontological equivalent of actually being alive. A potential life cannot give rise to rights and obligations. The transition from potential to being is not trivial, nor is it automatic, or inevitable, or independent of context. Atoms of various elements have the potential to become an egg (or, for that matter, a human being) - yet no one would claim that they ARE an egg (or a human being), or that they should be treated as such (i.e., with the same rights and obligations).
The Right to be Born
While the right to be brought to life deals with potentials - the right to be born deals with actualities. When one or two adults voluntarily cause an egg to be fertilized by a sperm cell with the explicit intent and purpose of creating another life - the right to be born crystallizes. The voluntary and premeditated action of said adults amounts to a contract with the embryo - or rather, with society which stands in for the embryo.
Henceforth, the embryo acquires the entire panoply of human rights: the right to be born, to be fed, sheltered, to be emotionally nurtured, to get an education, and so on.
But what if the fertilization was either involuntary (rape) or unintentional ("accidental" pregnancy)?
Is the embryo's successful acquisition of rights dependent upon the nature of the conception? We deny criminals their loot as "fruits of the poisoned tree". Why not deny an embryo his life if it is the outcome of a crime?
The conventional response - that the embryo did not commit the crime or conspire in it - is inadequate. We would deny the poisoned fruits of crime to innocent bystanders as well. Would we allow a passerby to freely spend cash thrown out of an escape vehicle following a robbery?
Even if we agree that the embryo has a right to be kept alive - this right cannot be held against his violated mother. It cannot oblige her to harbor this patently unwanted embryo. If it could survive outside the womb, this would have solved the moral dilemma. But it is dubious - to say the least - that it has a right to go on using the mother's body, or resources, or to burden her in any way in order to sustain its own life.
The Right to Have One's Life Maintained
This leads to a more general quandary. To what extent can one use other people's bodies, their property, their time, their resources and to deprive them of pleasure, comfort, material possessions, income, or any other thing - in order to maintain one's life?
Even if it were possible in reality, it is indefensible to maintain that I have a right to sustain, improve, or prolong my life at another's expense. I cannot demand - though I can morally expect - even a trivial and minimal sacrifice from another in order to prolong my life. I have no right to do so.
Of course, the existence of an implicit, let alone explicit, contract between myself and another party would change the picture. The right to demand sacrifices commensurate with the provisions of the contract would then crystallize and create corresponding duties and obligations.
No embryo has a right to sustain its life, maintain, or prolong it at its mother's expense. This is true regardless of how insignificant the sacrifice required of her is.
Yet, by knowingly and intentionally conceiving the embryo, the mother can be said to have signed a contract with it. The contract causes the right of the embryo to demand such sacrifices from his mother to crystallize. It also creates corresponding duties and obligations of the mother towards her embryo.
We often find ourselves in a situation where we do not have a given right against other individuals - but we do possess this very same right against society. Society owes us what no constituent-individual does.
Thus, we all have a right to sustain our lives, maintain, prolong, or even improve them at society's expense - no matter how major and significant the resources required. Public hospitals, state pension schemes, and police forces may be needed in order to fulfill society's obligations to prolong, maintain, and improve our lives - but fulfill them it must.
Still, each one of us can sign a contract with society - implicitly or explicitly - and abrogate this right. One can volunteer to join the army. Such an act constitutes a contract in which the individual assumes the duty or obligation to give up his or her life.
