The history of eugenics and the future of gene therapy.

In this commentary, I shall provide an overview of some recent histories of eugenics and suggest some lessons that this history may have for today. This commentary is not an argument against gene therapy. Rather, it is a plea for historical understanding of what has been done,..."in the name of eugenics."... There is a temptation to parody misgivings about gene therapy. I suggest that there are justified reasons to think about the social consequences of gene therapy. I do not hold that we ought to stop the program now, but I do believe that scientists, physicians, and the public ought to be aware of the slippery slope on which we as a society -- and we are all members of society -- have embarked.
