RT Journal Article SR Electronic T1 Defending human enhancement technologies: unveiling normativity JF Journal of Medical Ethics JO J Med Ethics FD BMJ Publishing Group Ltd and Institute of Medical Ethics SP 483 OP 487 DO 10.1136/jme.2010.036095 VO 36 IS 8 A1 de Melo-Martín, Inmaculada YR 2010 UL http://jme.bmj.com/content/36/8/483.abstract AB Recent advances in biotechnologies have led to speculations about enhancing human beings. Many of the moral arguments presented to defend human enhancement technologies have been limited to discussions of their risks and benefits. The author argues that in so far as ethical arguments focus primarily on risks and benefits of human enhancement technologies, these arguments will be insufficient to provide a robust defence of these technologies. This is so because the belief that an assessment of risks and benefits is a sufficient ethical evaluation of these technologies incorrectly presupposes that risk assessments do not involve value judgements. Second, it presupposes a reductionist conception of ethics as merely a risk management instrument. Each of these assumptions separates ethical evaluation from discussion and appraisal of ends and means and thus leaves important—indeed, essential—ethical considerations out of view. Once these problematic assumptions are rejected, it becomes clear that an adequate defence of human enhancement technologies requires more than a simple balance of their risks and benefits.
