but it's based on the assumption that a mind is not a continuous entity but a series of unrelated instances
Uh, what is absurd about that? Why would dead human beings have rights?
This is fine if we're talking about subjects where there's no disconnect between what the teleology says it's natural and what individuals usually want
On the subject of abortion, that brings us back to the familiar question: does a fetus have a presumed interest to become a person?
But what do the biologists mean when they say life?
So you claim that killing foetuses is wrong but don't need to point to some measurable property of being wrong because "wrong" is an adjective, and others claim that foetuses aren't people and need to point to some measurable property of being a person because "person" is a noun?
Such an argument from grammar is special pleading.
I don't understand your reply. You say there is no means to determine personhood, yet (if I follow you correctly) you agree that a country's legal system has to make that decision.
I don’t understand why I need to point to a property of “wrongness”. I also never said someone needs to point to a measurable property of being a person. I was saying there is no such measurable property, so it makes zero sense that I would say you need to point to one. — NOS4A2
My argument this whole time is that it’s wrong to intentionally kill a human being (unless he deserves it or it is in self-defense), to deprive him of life. A fetus is a human being. — NOS4A2

Echarmion asked "is this supposed to mean that there's no evidence for personhood?"
You responded with "I understand, and have no problem with either term in common usage, but if I were to ask you to point to whatever it is you're referring to you would invariably point to your body, which has existed and grown since conception. That's what I'm hung up on."
I am simply explaining that being (or not being) able to point to something has no bearing on whether or not someone is a person, just as being (or not being) able to point to something has no bearing on whether or not something is wrong.
If I ask you to show me what makes it a person... — NOS4A2
If you’re going to condemn some human beings to death because you’ve relegated them to the status of non-person, you better have something better than your own thoughts and feelings. — NOS4A2
And if I ask you to show me what makes killing a human embryo wrong?
There is a very real biological difference between an embryo and a baby. They might share the same kind of DNA, but there is much more to an organism than its DNA.
The baby was an embryo. — NOS4A2
I would refrain as best as possible from positing phantom properties and folk biology. — NOS4A2
It was an embryo, but now isn't. There is a very real biological difference between a baby and an embryo. That very real biological difference has moral relevance and is why it is wrong to kill a baby but not wrong to kill an embryo.
So are you now saying that it isn't wrong to kill a human embryo? Or are you refusing to show me what makes killing a human embryo wrong? This is why you are special pleading; you demand that we show you what makes something a person but refusing to show us what makes killing a human embryo wrong.
What biological differences make it not wrong to kill and embryo, but wrong to kill a baby? — NOS4A2
I’ve already described my reasoning and the entities it applies to as best as possible. — NOS4A2
The biggest and most relevant difference is that a baby is no longer being carried in the womb of its mother, and so for the most part the mother's bodily rights are no longer an issue.
Another significant difference is that the thalamocortical connections that are required for consciousness do not develop until ~26 weeks of pregnancy.
You've asserted that it is wrong to kill anything with human DNA (except in self-defence, etc.). You haven't justified this.
A sperm and egg are alive: no one disputes that. The fact is, also, that a human being begins to exist upon conception of those two. A sperm is alive, but is not a human; an egg is alive but is not a human, but a fertilized egg is a human. — Bob Ross
Yes, it is wrong to intentionally kill a fetus for the same reasons it is wrong to kill any other human being. — NOS4A2
You can disagree with the premise that a fetus is a human being, or that it is not wrong to kill human beings, but it’s difficult to reasonably do so. — NOS4A2
What if the mother wants the child. Does the zygote then deserve a chance at life and become worthy of protection.. — NOS4A2
All else being equal, we would expect the doctors to do everything they can to rehabilitate them and keep them alive. Circumstances matter, though, as, e.g., the doctors may have to prioritize one sick patient over another; but this is a reflection of limited resources and not a disrespect for human life. — Bob Ross
my human skill cell (which is a redundant way to put it btw) is not a human. — Bob Ross
A skin cell can be cloned and I think you'd need to be a biologist to distinguish a skin cell from a zygote, so it's amusing that you say a skin cell is not a human.
