The question of eugenics, which underlies this work throughout, is now discreetly present in biomedical practices that promote procreation (gene therapy, pre-implantation or prenatal diagnosis, reproductive cloning or genetic therapy). This is a completely different eugenics than the one practiced in the first half of the 20th century. Unlike state eugenics practiced in the past, contemporary eugenics does not seek to modify the human species and is not imposed. It is a private, negative eugenics, freely chosen by parents, legitimized by neo-liberal ideology. Since people who choose surrogate mothers and donor fathers, or who decide to eliminate a crippled fetus act on a strictly private and individual basis, what right do they have to interfere with their freedom?
