OK, let’s continue. Since last time you asked the questions, it is my turn to answer.
So, in your view, did she cease being a living human being?
She still had human DNA (which is not a precise term, due to some mutations) and her brain was reduced to vegetative functions. But to reduce a human “being” to having a human DNA, is not a good idea. It would elevate a tumor to the status of a “being”.
From where do you get that definition?
Common knowledge. The sapience is the highest brain function, being able to reach abstractions.
Unfertilized eggs are not an issue for me in this discussion (let me know if/why they are for you).
No, not for me. However many people equate a human being (or even person!) with the moment of fertilization, so for them losing a fertilized egg would be as significant as the miscarriage of a 3 month old fetus - if they would be rational about it.
Exactly - meaning that, just as the acorn/chicken egg comparison has holes in it, so does the chicken egg/human egg comparison.
No analogy is ever perfect. OK, here is another one.
Jane wishes to be a doctor, so she enrolls in a medical school. She made the
first step on the long road to become a physician. Does that first step allow her to be qualified as a doctor? Obviously not. Then she keeps learning, and every time her knowledge grows. At every successful exam she
makes another step on the road to become a doctor.
After the final exam, she has all the knowledge which is necessary to call her “Doctor Jane”. But she is STILL not allowed to use that label until she receives her diploma. It is a somewhat “artificial” requirement, but that is the case. Speaking about potential and actual distinction, the actual medical student is a potential doctor.
The steps for the zygote are blastocyst, embryo, fetus - then BIRTH - and finally a baby. However, contrary to the artificial boundary of receiving a diploma, the birth is more than an artificial dividing line. That is the moment when the symbiotic / parasitic relationship between the baby and the mother ends, when the baby becomes an independent human being. (Personhood is still an issue, but let’s leave it alone.) It still needs a lot of caring, but not the direct bodily resources of a woman.
Looks like we are making progress.
