What unique features does a foetus have that entitles it to moral consideration?
It has none, in my opinion, that aren't shared with cows or chickens, unless you include potential to become a human being.
Potential seems pretty abstract, to me. It might even include, say, a human ovum.
I'm also struck by our blithe moral inconsistency in applying moral consideration to extant humans (see Lyndon's post, above).
Potential, in this case, is pretty much everything. It might be different if that foetus had the potential to become anything BUT a human adult, but it doesn't.
There are only two choices here: this foetus becomes a specific, unique human adult....or it dies along the way. That's it.
A human ovum has the potential to become any one of, literally, billions of human adults, male or female, and even that potential isn't applicable unless it combines with a sperm cell.
I am pretty firmly against abortion, and for me, too, 'science' is the reason, not my religion. Shoot, if I went only with my religious beliefs, I could be more accepting of the idea. Not a great deal more accepting, true, but still....
No. At the moment of conception, when a sperm cell and ovum combine to one (or more, for identicals) unique human individuals. From THAT instant, the 'potential' you so discard narrows down to just two possibilities; death or eventual human adulthood. That's it.
Now I know of no modern human societies that think it is permissible to dash an infant's head against a rock because it only has the 'potential' to become a human adult....what's the difference between a foetus and that newborn, except the stage of its development?
Now me, I think that the rules of self defense apply here, too...the mother has the right to save her life at the expense of the foetus...especially since the choice is generally 'lose one or lose both.' I can even...though I hate this and wouldn't do it personally...see why a woman would want to abort a pregnancy that was the result of rape or incest (and incest IS rape), because THAT pregnancy was absolutely uninvited.
Abortion 'just because' is wrong. It is ending a human life...and in most cases, it's ending a human life whose beginning was the result of gross negligence on the part of the parents. There is very little excuse for an unplanned pregnancy nowadays, is there?
I mean, really.......there isn't.
Abortion isn't murder because murder is a legal term. It SHOULD be murder...and I note that in some cases, the law counts the death of a fetus at the hands of another AS murder; the murder of a pregnant woman is quite often counted as two, yes?
Ah, I'm shouting against the wind, here.
