Should we make people healthier, smarter, and longer-lived if genetic and medical advances enable us to do so? Matti Hayry asks this question in the context of genetic testing and selection, cloning and stem cell research, gene therapies and enhancements. The ethical questions explored include parental responsibility, the use of people as means, the role of hope and fear in risk assessment, and the dignity and meaning of life. Taking as a starting point the arguments presented by Jonathan Glover, John Harris, Ronald M. Green, Jurgen Habermas, Michael J. Sandel, and Leon R. Kass, who defend a particular normative view as the only rational or moral answer, Matti Hayry argues that many coherent rationalities and moralities exist in the field, and that to claim otherwise is mistaken.
