I was hoping to hear from an unbiased source. wkmac?
From all that I've read, the moment life begins is the moment of conception when you have a zygote. But at what point does that sub-dividing cell takes on the form of human and human consciousness? That is the great question that is the philosophical question of our age.
As for abortion, I'm personally against it on the grounds that it violates the non-aggression principle but my dilemma is I can't answer when that moment is that the fetus takes on some measure of self awareness and self consciousness. But then my other dilemma is I also can't use force against the mother (violates the non-aggression principle) because I can't answer that self aware problem and therefore if I impose my will, I could be wrong in doing so. I'm left with only I'll never get an abortion because of my philosophical position but then I'll never need one to begin with so there I am.
At this point I'm left with leaving it up entirely to the woman, hoping she makes the best decision, help her in any way to do so and thank goodness that the number of abortions have been trending down over the years. Let's just hope one day there will be no such thing anymore. I do agree with Rod, this issue is going nowhere and thus it should just be left as it is and move on to more important matter but the religious political movement in this country will not let it go.
I know it's not a cut and dry answer but for me there no clear answer at this point. Sorry that this is as little as I can give. You might find something worthwhile from
