We don't care about areas of philosophy.
You most certainly do.... any statement about value - whether you want to acknowledge it or not - is philosophical statement.
I by no means think the answer to the abortion question is obvious or undebatable or that my position is infallible, even though I've been strongly persuaded to call myself pro-choice. I don't think otherwise well meaning people are ghouls for having different values which lead to different conclusions, even if I think those values are misguided.
And furthermore, whether you like it or not, you are in a nation whose laws enshrine values that directly contradict your own. You're in a nation where at least half the population stands in direct philosophical opposition to your values.. so you better care about the relevant areas of philosophy if you intend to actually claim that your position is justified. And just as an aside, under such conditions, an appropriately cautious and humble person might just make a little room for the possibility that they are wrong on the issue, and not be so dogmatic and extremist as to wish death upon those who disagree.
We are talking about a beating heart. Stopping a beating heart. We are talking about a human.
So you think beating hearts are valuable (guess what... that's philosophy). I don't particularly care about them. I'm open to being convinced, but as I see it right now, hearts are just muscles. And muscles by themselves have no real morally significant qualities. I'd also argue that you don't really care all that much about them either, since newly conceived eggs don't have beating hearts... yet you want to protect them too no?
I don't particularly care about whether something is human or not. Living cadavers are human, the skin cells we are constantly shedding are human... the spit deposited on the dugout floor by a baseball player is human... heck, dead cadavers are human. The boundaries of my moral sphere do not start or end with things human...
The boundaries start and end with minds. At the moment, I see no good reason why I should care so much about things that do not have them. Now, eventually, a developing baby WILL have a mind, and there is definitely something to be said for that. I think we should value that potential. But in my opinion - the woman's rights and wishes is what really matters the most.
