Look, self awareness can’t be the defintion of “personhood”, or the point at which the right to life vests, because under that criteria infanticide up to 1 year old would be legal.
We’ve had one poster here on the Dope (Blalron) who argued just that. But I tend to think that’s a pretty fringe position.
So can we all agree that any definition that permits infanticide is a flawed definition? Yes, some people and some cultures actually do or did decide that infanticide was acceptable, but is that what we want today? Do we want a law that gives dolphins human rights but not 1 year old babies?
Of course, in my opinion Bricker’s “unique DNA” test fails also. There are people who share DNA, there are people who have two fused cell lines with distinct DNA. Identical twins are two people, not one, chimeras are one person, not two. Conjoined twins are two people, not one, despite the fact that they share a body.
The point is, there is no scientific way to determine what a “person” is. There is no scientific way to determine who should have the right to vote. There is no scientific way to determine who should have the right to life. These are ethical, religious, and legal ideas, not scientific ones. The question we should be asking ourselves is “what kind of society do I want to live in?” And if others come to some different conclusions, by what criteria can we claim that we’re right and they’re wrong?
I have no problem with the idea that we need not grant a right to life to a developing fetus that still lacks any brain activity. It seems pretty reasonable to me, in fact that’s the position I advocate. But that isn’t because it’s a scientific fact that said fetus isn’t a human being with a right to life. It’s an arbitrary moral decision. It’s a reasonable decision, from my point of view, and if people disagree with me I might try to convince them my position was reasonable. But I couldn’t prove that my belief was the only correct one…it’s just one that I’m comfortable with, one that I can live with.
It’s scientific only in the sense that it isn’t contradictory with any scientific evidence. But I could choose some other criteria, for instance, that only entities who are able to successfully fight for their lives have the right to live. That’s not inconsistent with scientific evidence either. But not many people would subscribe to such a doctrine. I wouldn’t want to live in a society founded on that principle, but that doesn’t mean the principle is wrong, just that I don’t want it.
Now, there are ethical propositions that depend on scientific justifications that are just wrong, like claiming that since fetuses have no brain activity they cannot be human beings. However, it’s factually wrong that fetuses have no brain activity, since a “fetus” refers to the stage after an embryo yet before birth, so a 40 week unborn baby is a fetus, despite the fact that they could have more brain development than a 30 week old premature baby.
So back to abortion. What sort of regulation of abortion do we as a society want? None? Really? What sort of rights does a woman have over a fetus developing inside her body? Absolute rights? Is that what we want? What sort of intervention are we as individuals or as a society prepared to take if someone disagrees with us?
And even if one believes that criminalizing elective abortion isn’t helpful, what about, say, arguing that one ought not to have an elective abortion? Is there anything morally wrong with trying to convince people that abortion is generally the wrong thing to do? Or with holding a position about the ethical status of the fetus that is more nuanced than others? There are some here who seem to argue that any nuance in discussing the moral status of unborn babies is wrong–since any wavering on the issue could or would lead to criminalization of abortion.
The thing is, there are lots of ethical questions that depend on an acceptable ethics of abortion. Take genetic engineering. If an unborn baby is just a thing, then genetically engineering a human embryo is no more problematic than engineering an ear of corn. But could we ethically modify an unborn baby to be a circus freak, or an subnormal slave laborer, or a headless clone for spare parts? If the fetus is just a thing, why not? It seems to me that a pretty simple ethical doctrine allows us to forbid such things, the doctrine of implied consent. If an unconscious person is brought to a hospital they are provided with medical care even though they are unable to consent to that medical care, because we recognize that almost all reasonable people would consent to such care, and if you don’t consent you’d have to make some sort of effort to make sure you don’t get unwanted care. So we can easily imagine that an unconscious person (the unborn baby) would consent to be treated for genetic disease, or perhaps even performance enhancing treatments, but almost no one would consent to be turned into a circus freak or sub-omeguloid laborer.
What’s wrong with the idea that a fetus has some sort of moral significance, even if perhaps it isn’t the same significance as 1 week old baby? Or that more and more moral significance attaches to that unborn baby as it develops, such that a fertillized egg or totipotent cell line has moral significance only in that it can’t be used to create monsters, a fetus with no brain activity has more moral significance but isn’t subject to coercive state protection, a fetus with brain activity can only be destroyed if it has gross abnormalities or harms the mother, and a viable unborn baby can’t be harmed?
