Now Here's a Debate on the Beginning of Human Life
George and Tollefsen assume a clear distinction between wholes and parts. Eggs and sperm are parts, they reason, while an embryo is a whole. At conception, the parts become a whole, the program launches, and personhood begins. But it isn't that simple. Some embryos divide after conception to become two or more people. Are those embryos, prior to twinning, an individual?And:
The egg-embryo distinction, too, is permeable. George and Tollefsen write that eggs must combine with sperm or die. They say an organism "was never itself a sperm cell or an ovum." But look what just happened at a zoo in Kansas: another case of parthenogenesis—eggs becoming offspring without fertilization. This process has produced adults in dozens of vertebrate species, including sharks and turkeys.I highly recommend that you read the whole article (and George and Tollefsen's response to Saletan's original review). It's a fascinating, intelligent back-and-forth on this blog's signature topic, the beginning of human life.
