Having participated in a number of these debates over the past few years, I've been surprised by how often certain arguments are trotted out with great solemnity, as if they were obviously right and true, even though a casual observer can quickly recognize their notable flaws and inadequacies...More
...I did my best to avoid letting our discussion slip into a polemic about what might work best, about efficiency, even though this was one of the key arguments used by my opponent. He stressed how embryonic stem cells appear to have certain desirable characteristics, and may one day be able to work better than adult stem cells, and if cures end up being derived from embryonic stem cells in the future, then, in effect, it must be ethical to do such research, and to destroy human embryos. This argument in one form or another has been put forward widely by the media, and has won over many Hollywood personalities, patient advocacy groups, and Washington politicians...
...A second argument that comes up quite often in debates about the embryo is the so-called argument from wastage. The starting point for this argument is the medical observation that most pregnancies don't survive and are flushed from a woman's body. One well-known embryology textbook summarizes it this way: "The total loss of conceptuses from fertilization to birth is believed to be considerable, perhaps even as high as 50% to nearly 80%". The fact that most embryos don't survive is then taken and used as a justification for destroying embryos to get stem cells. As another opponent of mine once put it during a debate at Southern Methodist University in Texas, "If Mother Nature destroys so many embryos naturally, why shouldn't we be able to as well? Why get all worked up about using frozen embryos in research, when so many early embryos die naturally from miscarriages?"
But the difference between a natural miscarriage and the intentional destruction of embryos is precisely the difference between the unfortunate case of Sudden Infant Death Syndrome vs. the unconscionable case of smothering an infant with a pillow. What Mother Nature does and what I freely choose to do as an acting person are two separate realities, not to be confused.
