So, before I do some more research, you are saying moral personhood should be the defining factor for what is human?
Definition: Human: a thing that possesses moral personhood<---like that?
No. I am saying 3 things.
Moral Personhood is not a sufficient nor a necessary condition of being Human.
Being Human is not morally significant.
Moral Personhood is morally significant.
U sure? You think moral person hood is not a sufficient nor a necessary condition[/u] of being Human? So, in Max brook's book, what would you define the term 'human factor' in world war z? What makes a zombie different from a human?
Do they need to be different? Aren't zombies humans that were infected with the zombie plague?
Am I sure that it is not a sufficient condition? Yes, see chimps.
Am I sure that it is not a necessary condition? Yes, see comatose humans.
Let me first ask if you have read the book. Secondly, look how the people react when they see their human beings, sometimes their loved ones, infected. They are not the same person. Their character has changed. Their 'humanness' is not the same. Kind of one of the moral reasons to get a divorce: your wife is a completely different person than the one you married. Yes, they are human, but their 'humanness was lost.'
Comatose human: still the same guy. Will act the same and think the same. (Mass Effect 2 where they put that guy back together-->still the same person).
Chimps: what are chimps missing that makes them non-human? Also, let's assume the chimp had the same genetics as you and me. It can do a lot of parenting things, but scientists to this day still cannot say if animals actually mourn the loss of their kids and vice versa. Sure, they call out to them when needed, but when they die...it's surprising the reaction. I am conflicted though because of when that military guy died back in 200(6-10)...was all over the news, his dog knew he was dead and mourned.
Now, this brings up an interesting topic: there are people I have seen on video after car crashes that the collision on their head so severe they lost all memory. Was like a 1yr old kid in a 50yr old body. Although they are no longer the same person, they still retain their 'human factor.'
