….No one should underestimate the wrenching challenge of having a disabled child. But we also should not ignore the social consequences of widespread screening of children for “desirable” traits. This kind of “choice” is actually a form of absolute power of one generation over the next — the power to forever define what is “normal,” “straight” and “beautiful.” And it leads inevitably to discrimination. British scientist Robert Edwards has argued, “Soon it will be a sin of parents to have a child that carries the heavy burden of genetic disease.” A sin. Which leaves disabled children who escape the net of screening — the result of parental sin — to be born into a new form of bastardy and prejudice.
This creates an inevitable tension within liberalism. The left in America positions itself as both the defender of egalitarianism and of unrestricted science. In the last presidential election, Sen. John Kerry pledged to “tear down every wall” that inhibited medical research. But what happens when certain scientific views lead to an erosion of the ideal of equality? Yuval Levin of the Ethics and Public Policy Center, a rising academic analyst of these trends, argues: “Watson is anti-egalitarian in the extreme. Science looks at human beings in their animal aspects. As animals, we are not always equal. It is precisely in the ways we are not simply animals that we are equal. So science, left to itself, poses a serious challenge to egalitarianism.”
