I guess I should start by saying that while I consider myself very liberal my own views on abortion are still in the process of being hashed-out, hence this thread. I am not at all religious so I have tended to approach the debate in a purely secular manner based on my own ethics, morals, and (limited) understanding of human development. It seems to me that far too often the issue of whether we should allow abortion is separated into a “no abortions never” vs. “any attempt to restrict any type of abortion is an assault on a woman’s right to choose” dichotomy. This approach does not make much sense to me mainly because of the historical stances of the more extreme voices in these two camps: today, most people probably believe that contraceptives such as condoms are ok and most people also probably believe that infanticide is not-so-ok, but this has not always been the case. I can understand how opposition to things like legislation restricting “late-term” abortion have are partially based on the belief that one concession on an issue will lead to more down the road, but it seems to me that many of the interested parties are approaching the issue with a tactical, political bent and not addressing the single-most important question here, which is when (or at what stage) exactly does the act of destroying the product of a sperm cell and egg cell (or a sperm or egg cell itself, for that matter) constitute an immoral act. It seems reasonable to me that a woman should have control over a part of her body that could not exist without her supporting it (ie abortion in the early stages), but due to advances in medicine we now have the ability to keep some alive today which would have died outside of the woman’s body before, and we can only assume these capabilities will continue to change with further advances. Does this mean that the point in development at which such an act is immoral depends on the context of the scientific capabilities in which the pregnant woman lives (ie the immorallity of aborition is not a universal concept)? I guess my main issue is to try and determine where, if anywhere, we can draw a line in the span of a human’s development that seperates whether its destruction is moral or immoral. It seems like two easily definable points, ones that many have latched onto for their pro-life or pro-choice arguments, are the point of conception and the moment of birth. I don’t really think these two points are all that reasonable (partially for the reasons mentioned above) and I feel likethe vast majority of Americans agree with me. So is there some other easily definable point in our development that should serve as the marker? Is it when we become self-aware? (Is that even before we are born?) Is it when we are able to survive on our own, and, like I mentioned before, does that take into account the current state of medical technology in the society in which we live? I would be very interested to read what other people think about this issue.
ps - I found one other thread that seemed to touch on this subject, http://boards.straightdope.com/sdmb/showthread.php?t=29746, but it was old and the discussion broke down toward the end.
