"Stop someone from what?"
Doing anything they want.
"that doesn't mean that it is in the long term interests of the majority."
I'm sure that the majority is always thinking of its long term interests.

"The history of moral evolution has proceeded in fits and starts, but it has progressed to the point where a large number of people can coexist with each other in relative peace and harmony."
That's some wishful thinking and historical revision if I've ever seen it. It was only in the last century that we saw some of the worst abuses in the history of humanity. Abuses still persist. They just don't make the headline news.
"It didn't take you long to play the Nazi card."
Because it's the same d*mn thing. One group of persons deciding another group of persons aren't persons at all.
"Again, the majority opinion does not always work in achieving a stable, peaceful society, which is, after all, one of the goals of society."
You are clearly not grasping the point. You are actually conceding my point. If personhood resides in the consensus of the majority (or, a minority with the power) then at no point can any human consider himself safe. Your argument that eventually (or hopefully) the majority will conform their moral system to what is in their 'best interests' is irrelevant to my assertion. You are admitting that I am correct in my analysis.
Naturally, I believe that a proper moral system will in fact lead to 'peace and harmony' and a 'stable, peaceful, society.' However, I understand something you do not, which is if what is 'moral' is dependent on the ruminations of each individual human, then there is no basis for negotiation.
To put it simply for you, you are assuming that a society has a purpose- safety and security. But that is just your opinion. Others have thought that the purpose of society was something else, and their morality- since it was of their own making just as their views on the purpose of society is- was geared towards that.
In short, your approach will never achieve the peace and harmony you seek. There will always be atrocities and genocides where ever your approach is tried. You apparently are ignorant of the fact that it
was tried at the end of the 19th century.
"According to you, the answer would be divine revelation. Wink"
Why the wink? That is in fact my answer.
"Divine revelation is not needed to prevent us from treating infants as if they were not real persons."
I think history shows otherwise.
"For starters, it lacks a brain."
I'm sorry, but where is it written that a thing needs to have a brain in order to be considered a person? How did you arrive at this conclusion? Seems like arbitrary plucking to me.
"Part of what we mean by "person" is that the entity so categorized is capable of rational thought."
This sums up the utter incoherency of your position. The idea that what we mean by 'person' means 'is capable of rational thought' is at best, a mere 'majority consensus.' At any time any one likes, on your terms, we could change the definition so as to mean anything anyone wants.
It hasn't apparently occurred to you that between the two of us, it is me trying to get you to understand the 'long term interests of the majority.' Only one of us has a view that will perpetuate human life and dignity, even the weakest humans among us. Your views certainly will appear to be in the 'long term interests of the majority' but of course here again, 'long term interests' is derived from consensus, and the way things are looking a lot of policy makers are looking at the bottom line in order to make that calculation. If you are on your death bed and the state won't give you the medicine that would save your life because the medicine is expensive and you are not deemed productive to society, don't blame me.
After all, one of the definitions of 'personhood' is that a person is productive to society.
"The difference is insignificant. If science were able to clone full human beings from any body cell, that would not change their status as non-persons. Embryonic masses of cells are not 'persons', regardless of what they would become if allowed to develop."
So cloned human beings are non-persons? I was wondering where you would stand on that.
"Forcing women to bring pregnancies to term is cruel, irresponsible, and immoral."
Well, that's just your opinion. Opinions change as morality evolves. We need not think much of your view here.
"You are becoming seriously confused. My position is that embryonic cells do not qualify as 'persons'. Yours is that they do. You equate the potential with reality."
No, that's not what is going on. You invoked potentiality, not me. You tried to say that the potential of an embryo is the same as the potential of any living cell in a human. An embryo will indisputably turn into a human. Living cells in our bodies indisputably will not. Your assessment that we will with scientific technology be able to turn living cells into humans and this is the same kind of potential is completely flawed. For one thing, this same technology (which does not exist and may never, even if 100% unleashed) could take those living cells and turn them into, say, kidneys. An embryo will never turn into a kidney.
So even if you are right that we could make humans out of any living cells that does not mean it has the same kind of potential.
An embryo is like an arrow in its flight path. It will always arrive at a specific, predictable flight path, unless someone meddles in the meantime. An embryo is just the arrow 1 second after it leaves the bow. That is the kind of potential here.
A living cell is like a rock falling to the ground. It's potential is that it will complete its cycle and die, without producing a copy of the thing which created it. If someone catches the rock as it falls, you can argue that he can run over and put it right on the same target that the arrow would have hit, but he also could take it into his house to use as a paper weight. Or he can bean someone in the head with it.
The use of 'potential' in these two situations are categorically different senses of the term.
"This is a tired straw man, and we've covered this territory before."
It is the future if you and your ilk get their way.
"Dying and comatose people are full members of society, unlike embryos and fetuses."
Remember what you said:
"Part of what we mean by "person" is that the entity so categorized is capable of rational thought"
Comatose people are not capable of rational thought. Hence they are not persons. This isn't a strawman, this is you not being consistent. Everywhere you turn you bang your head against a piece of objective morality that alerts you to the fact that your perspective, if pursued to its logical end, would result in barbarism. Your answers are plainly ad hoc attempts to show how these are not the logical ends. Unfortunately, they are.
"They have formed relationships with people,"
An embryo has a relationship with its mother. Mothers are still people, right?
"they own property,"
Sure, I can totally see why this would be a component of personhood. Now I can see how the southern slave owners were right to deprive blacks from voting as full citizens. After all, blacks didn't own property. (Note to self: In quest to take over the world, if there are any 'humanish' 'things' that I want to exterminate first deprive them of their property and put them into comas. Then I will be able, in good conscience, to hook them up to my own private Matrix or otherwise dispose of them as I will)
"and they have a potential to recover."
The unborn does not have the potential to recover? Sure, if you stick a knife in its skull and suck out its brains I can see that it would be hard to come back from that, but that seems to me to be the case for comatose people, too.
"There is a big difference between fetuses and babies that can live outside of the womb."
It's the Copernicus Comedy Hour. On the one hand, the difference between the potentiality of an embryo and a living cell is 'insignificant.' On the other hand, the difference between a fetus and a baby is 'big.' This is just too much! lol

"You seem to have missed the fact that I have never claimed that what society defined as 'right' was objectively 'right'."
lololol no, I didn't miss it. That was really my point lolol
"it is human well-being that ultimately defines what is moral and what is not."'
That's just your opinion. If you were a cannibal you'd think differently.
