Eugenics: some lessons from the past

Eugenics was first debated by the ancient Greeks, particularly Plato and Aristotle, developed in the nineteenth century by Francis Galton and Charles Darwin, and then abused in the twentieth century by right-wing politicians. With the new methods of assisted conception combined with the use of genetic markers, all the old problems of eugenics have resurfaced. Gender selection, embryo selection, preimplantation genetic diagnosis of common disease, and gene replacement techniques (somatic cells) have added greatly to the power of the modern eugenicist. How are these procedures to be monitored and regulated? What is the role of the State compared with individual families for the implementation of the new methodologies? Some of these issues will be discussed.
