Maybe within a framework of "necessity" but def not "morality".Has the philosophy of what constitutes "life" and "sentience" been completely explored, established and agreed upon? Is it fact that fetuses have no unique sentience of their own? Who decides that? And if that is all still up in the air, then why take the position where innocent life pays the price instead of protecting it?
What if you're wrong? What if the arbitrary number/age assigned to sentience was wrong? What if the child fears/feels everything during abortion (there are hints to this at 8 weeks btw). Imagine sentencing someone to the death penalty even tho guilt isn't even all that clear yet. Imagine sentencing a helpless, innocent child to that.
Sentience is relative. And so is the system of assigning rights within a level of perceived "sentience". Does a mentally underdeveloped child now have less rights to life than a fully developed one? Is killing an underdeveloped child now less wrong that killing a normal one? As arguably, one can claim that one has a higher sentience than the other? To claim morality/justice, right to life has to be consistent throughout. We don't get to pick and choose.
See, I'll have to completely disagree with this line of thought. Who are we to decide what is proper or functioning? Newborns are no more "proper" nor
"functioning" by the definition of the word than fetuses, yet they seem to have rights to life. We need to be consistent on who gets the right to life and who does not.
To the first question of 'who decides'- that's an excellent question that is at the centre of the debate. Basically, right now, it's the law. But to take the UK as an example- when abortion was legalised, it was set at a maximum development point where it was felt after which the fetus could survive outside the mother, so that was the criteria taken.
But that was always silly as, inevitably, decades later, medical technology has advanced so that fetuses have become viable much earlier so any moral strength that limit had is lost- it's now just an arbitrary number. But no-one can think of a better alternative.
Has the philosophy of life etc been completely explored? Absolutely not, and hence the ongoing nature of this debate. Why not use science? Because generally people don't have faith that scientists have accurately defined what a sentient human is either- an organic human, maybe, but that's not the same thing. The doubters, incidentally, include the majority of the scientists, where this debate is just as strong as anywhere.
When you say 'what if 'you' are wrong'- I didn't state a position, so I am assuming you mean an average pro-choice proponent. Well, then the answer is, if they are wrong, there is a lot of moral murder going on. But what if the pro-life person is wrong? Then there is a staggeringly huge amount of destroyed lives going on when abortion is not available- and that one we know for certain, unlike the murder thing which is speculative.
All that about mentally undeveloped children is an irrelevance I am afraid. Relativity does not enter into this- the view by pro-choicers is that fetuses before a certain point have zero sentience- none at all. When sentience starts to develop would be a theoretical cut-off point.
The simple truth is we don't know for sure the absolute truth of this- and all we can do is debate about a time limit with the best information we have. But I am afraid your idea that science has it cut and dry has no wider acceptance in any culture. Most fervent pro-lifers base their thinking on religious philosophy.
