As one anonymous commentator noted, one of the problems with slippery slope arguments is that they fail to argue against the thing they claim to argue against. They seem to argue against more extreme things. To illustrate this point, two bioethicist types argue in the Washington Post:

>We have seen where this amoral logic leads us — to shameful abuses of research subjects, which surely no one wants to repeat. But we have also seen, in the stem cell debate, how moral lines erode quickly — from using only “spare” embryos left over in fertility clinics to creating human embryos solely for research to creating (or trying to create) cloned embryos solely for research. What will be next? Probably proposals for “fetal farming” — the gestation of human embryos to later developmental stages, when potentially more useful stabilized stem cells can be obtained and organ primordia can be “harvested.”

They forgot to mention soylent green. The problem, of course, is that it isn’t logic that leads us there. It’s the hyperbolized rhetoric of policy advocates, such as the authors of this piece. So, by way of illustrating the observation of the commentator, what is wrong with stem cell research as it is now (or as it is proposed by various bills)? When you answer, don’t tell us about embryo farming. But if you do tell us about that, tell us what is wrong with it. For the real slippery slope, such as this one, argues neither against the top nor the bottom of the slope.
