Nicholas Agar (born 1965) is a New Zealand professor of ethics at the University of Waikato. Agar has a BA from the University of Auckland, an MA from the Victoria University of Wellington, and a PhD from the Australian National University. He has been teaching at Victoria since 1996. Work on human enhancement Agar has written extensively on the debate about human enhancement and eugenics. His first significant contribution was the 2004 book Liberal Eugenics: In Defence of Human Enhancement. In the state-sponsored eugenics defended by the followers of Francis Galton individuals would defer to the state and its experts empowered to impose on all a centrally-determined conception of the good life. Agar argued that a vigorous defense of procreative freedom could turn the morally misguided authoritarian eugenics into a morally defensible liberal eugenics. Agar would encourage prospective parents to consult their own conceptions of the good life to choose some of their children's characteristics. A liberal state should ban choices judged injurious to children's well-being. It would exercise the same kinds of control over harmful genetic choices that it currently does over choices about how to raise children. Later work clarified Agar's philosophical focus on enhancement. The 2010 book Humanity's End argued against the doctrine of radical enhancement sometimes identified with the transhumanist movement. Agar claims that enhancement is a good thing that it is nevertheless possible to overdo. He advances a species-relativist view about the value of human experiences and achievements. Viewed from the perspective of our species-relativist preference a little enhancement goes a long way. Humanity's End was a 2011 Choice Magazine Outstanding Academic Title. In his 2013 book Truly Human Enhancement Agar presented too much enhancement as an instance of transformative change. Agar defines transformative change as altering "the state of an individual's mental or physical characteristics in a way that causes and warrants a significant change in how that individual evaluates a wide range of their own experiences, beliefs, or achievements." He uses examples from the movie Invasion of the Body Snatchers to make the case that there are transformative changes that we correctly predict we will endorse once we have undergone them but that conflict with our prudential values. The central characters in the body snatchers movies resist snatching by the aliens even if they expect to be content about this change once they have undergone it. We may predict that we will enjoy
