Risk, Health, and Physical Enhancement: The Dangers of Health Care as Risk Reduction for Christian Bioethics

Medicine increasingly envisions health promotion in terms of reducing risk as determined by quantitative risk factors, such as blood pressure, blood lipids, or genetic variants. This essay argues that this vision of health care as risk reduction is dangerous for Christian bioethics, since risk can be infinitely reduced leading to a self-defeating spiral of iatrogenic effects. Moreover, it endangers character because this vision of health is connected to a reductionist vision of the body and an understanding of individual risk that undermines the more communal virtue of solidarity. The essay concludes by discussing how recent Thomistic analyses in favor of physical enhancements illustrate some of the problems that envisioning health care in terms of risk reduction holds for Christian bioethics.
