What's wrong with designer children, bionic athletes, and genetic engineering.

In a sense, all technology is biotechnology: machines interacting with human organisms. Technology is designed to overcome the frailties and limitations of human beings in a state of nature -- to make us faster, stronger, longer-lived, smarter, happier. And all technology raises questions about its real contribution to human welfare: are our lives really better for the existence of the automobile, television, nuclear power? These questions are ethical and political, as well as medical; and they even reach to the philosophical (...) and spiritual. On the whole, we seem pretty well adapted to our technology, at least on the face of it -- but there have always been doubts about whether the human soul thrives best in the oppressively technological world we have created for ourselves. (I am continually struck by how much time I have to spend fixing the machines that supposedly improve my life.). (shrink)

Suppose that we develop a medically safe and affordable means of enhancing human intelligence. For concreteness, we shall assume that the technology is genetic engineering (either somatic or germ line), although the argument we will present does not depend on the technological implementation. For simplicity, we shall speak of enhancing “intelligence” or “cognitive capacity,” but we do not presuppose that intelligence is best conceived of as a unitary attribute. Our considerations could be applied to specific cognitive abilities such as verbal (...) fluency, memory, abstract reasoning, social intelligence, spatial cognition, numerical ability, or musical talent. It will emerge that the form of argument that we use can be applied much more generally to help assess other kinds of enhancement technologies as well as other kinds of reform. However, to give a detailed illustration of how the argument form works, we will focus on the prospect of cognitive enhancement. (shrink)

Cognitive enhancement takes many and diverse forms. Various methods of cognitive enhancement have implications for the near future. At the same time, these technologies raise a range of ethical issues. For example, they interact with notions of authenticity, the good life, and the role of medicine in our lives. Present and anticipated methods for cognitive enhancement also create challenges for public policy and regulation.
