From my view that IS what you are saying. I'm just not cashing the check you are trying to write. A human life is a human life at whatever the stage of development. It IS a rationalization, but abortion proponents have that problem within their arguments. I know I'm not going to change minds.
To answer your question: If a woman's life is in danger and the physician was able to determine that her life could only be saved by her aborting the unborn child, than without question it would be morally acceptable to perform the procedure to save her life. This is a specific circumstance that I'm sure occurs, but that circumstance in no way changes the dynamic of the argument that abortion is a moral evil.
I don't know the whole of the philosophy to which you ascribe, but I know enough from the few conversations we've had that, and the comments of yours over time, to know I'm close enough for the purposes of this conversation.
You don't deny that science continues to provide more evidence that embryos, fetuses (is that the plural of fetus? Feti?), but you're point of view doesn't change to reflect that or even allow for the possibility that it is a human life. The crux of the matter is that the taking of a human life is unjustifiable killing. I don't believe that you, Octavia, would support murder under any circumstances, but you really need to think about this outside of this conversation, because you could find yourself doing just that as science continues to provide additional evidence. What, do you think, would a scientific inquiry have to provide to convince you otherwise? Are you even convince-able?
You surprised me. I thought everyone would assume that human life is intrinsically valuable and worthy of protection. You didn't say so, but since you point out that is not science but my worldview (which is true), it sounds like you have a different view and I would be interested in hearing it. Maybe this is where we part company. If you don't believe in the intrinsic value of human life, then you WOULD have an easier time terminating a baby at an early form of its development, because there's nothing special about being human. But you have to be careful with that kind of thinking. It's a slippery slope.
