A Not So New EUGENICS Harris and Savulescu on Human Enhancement BY ROBERT SPARROW

John Harris and Julian Savulescu, leading figures in the “new” eugenics, argue that parents are
morally obligated to use genetic and other technologies to enhance their children. But the argument
they give leads to conclusions even more radical than they acknowledge. Ultimately, the world it would
lead to is not all that different from that championed by eugenicists one hundred years ago.
