We want elite pilots to fly our planes, elite troops to undertake our most critical missions, elite athletes to represent us in competition and elite scientists to devote the most productive years of their lives to curing our diseases. Ask yourself: how has "elitism" become a bad word in American politics? There is simply no other walk of life in which extraordinary talent and rigorous training are denigrated. “What is so unnerving about the candidacy of Sarah Palin is the degree to which she represents-and her supporters celebrate-the joyful marriage of confidence and ignorance. Every time you scratch your nose, you have committed a Holocaust of potential human beings.”
But almost every cell in your body is a potential human being, given our recent advances in genetic engineering. Perhaps you think that the crucial difference between a fly and a human blastocyst is to be found in the latter's potential to become a fully developed human being. If you are concerned about suffering in this universe, killing a fly should present you with greater moral difficulties than killing a human blastocyst. If it is acceptable to treat a person whose brain has died as something less than a human being, it should be acceptable to treat a blastocyst as such. It is worth remembered, in this context, that when a person's brain has died, we currently deem it acceptable to harvest his organs (provided he has donated them for this purpose) and bury him in the ground.
Consequently, there is no reason to believe they can suffer their destruction in any way at all. The human embryos that are destroyed in stem-cell research do not have brains, or even neurons. There are, for the sake of comparison, more than 100,000 cells in the brain of a fly. “A three-day-old human embryo is a collection of 150 cells called a blastocyst.
