This is the process used in the sciences, where theories are compared not just against each other but against how things are. — Banno
And science is the process where we inquire about what a human being is, what a pregnancy is, comparing newborns to adults to zygotes. Science, like metaphysics, physics and biology, theory of mind, psychology, but in the context of abortion, really mostly biology and medicine.
In ethics we compare the theory against how things ought be. The point of doing ethics is that how things are never tells us how things ought to be. We have to decide that for ourselves. — Banno
I agree that morality and ethics are a separate inquiry, where we take what science tells us, whatever we now agree is most rational/factual/state of affairs, develop our ethical/moral/legal norms, and apply them to the state of affairs. We say “this a pregnant woman and as a human being, she is entitled to many rights, and ought be treated as all human beings ought be treated.”
So how should things be? Well, for one thing, a bunch of cells ought not be evaluated as of the same worth as Mrs Smith. Mrs Smith has qualities not had by the cyst that qualify her as of greater value. If a theory does not agree with this evaluation, it has gone astray. — Banno
Mrs. Smith is a bunch of cells. Calling a human zygote a bunch of cells or a cyst doesn’t say anything.
Saying Mrs. Smith “has qualities not had by the [zygote cyst creature you call it]” is an assertion about what a human being is, but it’s not an argument.
Are you saying that only entities who demonstrate certain “qualities” that are of “greater value” shall be recognized as human beings? (That’s a scientific question.)
Or are you saying that a human zygote is a human being, and Mrs. Smith is a human being, but because Smith at the later stage has these high value qualities, and the zygote human doesn’t, we can kill the zygote anyway due to some moral law manipulation and exception creation surrounding the prohibition against killing human beings? (That’s the moral/legal question?)
The monotony of this for all of us is that some pretend the science to talk about ethics, and others pretend the ethics to talk about science. No one is attempting to simply get it right.
And we should do the science first. Who cares about abortions in the first month if we metaphysicians and biologists can say “a 4 week old human fetus can’t be a human being because all humans must have A, B, and C, and a zygote doesn’t have any of those.”??
The answer to when in the unfolding of time does a new human being come into being (such that we can no longer kill it morally) is an essential part of this debate, because only after there is any human being can there possibly be a life of any sort or value that could be be treated immorally.
So let me ask you the scientific question: Does a brand spanking new born baby have enough of the same high value qualities as Mrs. Smith, that it makes sense to protect them both as human beings, as persons (which the whole world already does)?? Why are new babies more special than “cysts” or the human zygote stage? What are the qualities of living bunches of cells that cross the threshold and have to be called “human beings” and when in the history of any of us adult humans does that threshold get crossed?
I’m hoping you to choose some behavior and functioning (some qualities is better) occurring after conception and before natural, adult death.
I’d be surprised if the human qualities you state, beyond having human DNA, will include both a newborn baby (which is more like a plant, or like a fetus without its needed uterus/ life support system) and Mrs. Smith? What human qualities cover the adult and the newborn but leave out the human zygote? Maybe some abortions do not involve killing human beings (at 3 weeks) while others do (at 8 months)? So what are the high value qualities of human being that cover both? Or should we be making it legal to kill unwanted baby children? I’m open to those discussions if the science takes us there.
