Book excerpt: Medicine has recently discovered spectacular tools for human enhancement. Yet to date, it has failed to use them well, in part because of ethical objections. Meanwhile, covert attempts flourish to enhance with steroids, mind-enhancing drugs, and cosmetic surgery—all largely unstudied scientifically. The little success to date has been sporadic and financed privately. In How to Build a Better Human, prominent bioethicist Gregory E. Pence argues that people, if we are careful and ethical, can use genetics, biotechnology, and medicine to improve ourselves, and that we should publicly study what people are doing covertly. Pence believes that we need to transcend the two common frame stories of bioethics: bioconservative alarmism and uncritical enthusiasm, and that bioethics should become part of the solution—not the problem—in making better humans.
