Beyond Humanity? The Ethics of Biomedical Enhancement
Allen Buchanan’s latest book, Beyond Humanity, is a refreshingly subtle, biologically informed defense of biomedical enhancement. Buchanan doesn’t take a proenhancement position so much as (in his words) an ‘antianti-enhancement’ position (13). This distinguishes him from conservatives like Leon Kass and Michael Sandel, who decry the use of medicine to improve our existing capacities, but who tepidly embrace it to treat disease. But it also sets him apart from ethicists like Julian Savulescu, who recently suggested that we have a moral obligation to enhance ourselves and our children under certain conditions.
