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.
