Sloth,
I have to applaud you. You are the first person I’ve heard/seen in a long time who is willing to state his beliefs and back them up with their reasoning. I actually agree with most of your opinions (if not for the religious reasons behind them) but I have to say that the abortion thing seems to be a bit more complex than most people make it.
The question as to when life begins is all to often argued, one way or the other, by quick summations and one line statements. Such as “it has DNA, it’s a life” or “it doesn’t breath, it doesn’t count” etc… I find myself in awe of the fact that people can oversimplify something of such seeming importance.
To determine when life begins, i.e. whether or not a fetus is, in fact, a life and counts as a person, we first need to define life and person. These are matters of philosophy and science, not morality. So what defines life? How does one distinguish between the living and the non living?
Wikipedia gives this as the conventional scientific definition of life:
Certainly an early term fetus can be said to meet the requirements of 2, 3, 4, and 7 (as a function of 4). However, 1, 5, and 6 are not so clear cut.
A fetus relies almost entirely on the mother for homeostasis (point 1). Later in the pregnancy the fetus may or may not be capable of handling these functions on it’s own, but it doesn’t actually do so until birth. So judging by that, a fetus doesn’t count as a life until it’s capable of maintaining homeostasis on it’s own.
Next, Adaptation. Does a fetus have the ability to change over a period of time in response to its environment. Well, to use a terrible example, look at FAS (Fetal Alcohol Syndrome) or crack babies. Babies are capable of getting addicted to drugs used by the mother, hence adapting to this substance introduced into their environment. It’s not necessarily good adaptation, but it seems to meet the requirements.
Third we have response to stimuli. Is a fetus able to respond to some form of external stimulus. Here we have the same issue as with number 1. After a certain stage in the pregnancy, yes, babies can kick and move and do all sorts of things in response to being poked or exposed to music, etc… But in the early stages of pregnancy, I’d have to say no, this requirement is not met.
So, for the most part, especially in later pregnancy, a fetus meets the requirements for life by the conventional scientific definition. Great, so do cats, dogs, mice, birds, plants, and even amoeba and algae. Should it be illegal to kill algae? Or pick flowers? What about euthanizing a sick petor eating meat? No, obviously none of these things constitute homicide. So we come to our second big question, does a fetus constitute a person and how do we define person?
This is where things can get philosophical, but from a purely scientific point of view, yes, a fetus has the genetic characteristics of Homo Sapiens Sapiens. However, so do hair clippings, and severed limbs, and dead people for a while, and as far as I know, it’s not illegal to kill them, again. But obviously, a fetus is not the same as a cadaver. But also, as we established earlier, the fetus doesn’t quite meet all the requirements for life. So we’re stuck somewhere in the middle. Not technically alive, but obviously not dead. This poses an awkward conundrum. Traditionally life and death are mutually exclusive. If something isn’t alive, it’s dead, and vice versa (except of course zombies, vampires, and inorganic materials like minerals, metals, etc…). This sticking point is the same as last year’s Terry Schaivo(sp?) debate. How does one classify something or someone who doesn’t meet all the requirements for life, but at the same time, doesn’t lack enough of them to be qualified as dead? This I don’t have an answer for so I put it to you for debate.
Regardless of the answer to that question, we still need to define what separates humans from other living beings, and determine whether or not a fetus meets those requirements. This, however, is a much more complex question that philosophers and scientists have been discussing and debating for ages and I’m not sure I’m qualified to discuss it, so I won’t. I just wanted to express my opinion that the issue of abortion is infinitely more complex than it’s made out to be in typical arguments.
However, when it comes down to it, right now, it’s legal in this country and until someone can prove that the Roe v. Wade judgment was legally (not morally or ethically) flawed, or someone concretely and scientifically demonstrates that a fetus is, in fact, alive and fully qualifies as a person in both the scientific and philosophical sense, then there is no legal justification for changing the law.
Just my $.02,
Jay
