women say "It's my body." Well, not really. The father contributes
more genetic material to an embryo than the mother does. In any case, the
developing child has his own blood type and his own DNA, similar to his
parents', but not identical. Medical opinion, based upon observance, realizes
that an unborn child is a separate entity, and simply not an appendage in the
mother's uterus, which she can remove if she so wills.
One of the arguments for abortion says that since the fetus or embryo is not yet a sentient being, his life has no moral value. Take the case of a sleeping adult. There may be some mental activity going on, but for most purposes, she is not sentient so we are justified in terminating her life? But, the argument goes, when she awakes, she is sentient again. Suppose, as a result of a serious accident, she lapses into a coma. She is certainly not sentient then. Would it be permissible to end her life then? Not really, because she still has the potential of returning to a sentient state. The potential. Yes, exactly what a fetus has - the potential.
Take another argument. Some will say that a being so small cannot possibly have a moral value. Taking that argument, we would have to say that a basketball player is more human than say, a ten-year-old child because he is bigger. Viable babies as young as 24 weeks have been safely delivered, and although they need constant care to preserve that infant life, it is still life. Deprived of sustenance for a few days or even a few hours he will die. In the same way, any healthy adult deprived of air for a few minutes, water for a few days and food for a few weeks will also die.
A few years ago I attended a moderated debate on whether abortion was justified or not. Both debaters advanced logical arguments, but I think both of them missed the point. The point being that young women faced with an unexpected pregnancy don't weigh the logical pros and cons, but decide on the basis of emotion.
Is she prepared to terminate the life of a human being that she knows full well is growing inside her? Is she prepared to deal with the thoughts that come crowding into her mind when she wakes up at three in the morning just after an abortion? Is she prepared to face the fact that just a few days ago there was a living human being sharing her life, but now there is nothing - just an emptiness that no amount of logical debate can fill? These are questions that demand an answer, and so far, abortion activists seem incapable of answering them.
