The defining debate in this new century will be about technology and human enhancement, according to many across the political spectrum.[1] Our ability to use science to enhance our bodies and minds – as opposed to its application for therapeutic purposes – is one of the most personal and therefore passionate issues in an era where emerging technologies seduce us with new and fantastic possibilities for our future. But in the process, we are forced to rethink what it means to be human or, essentially, our own identity. For some, technology holds the promise of making us superhuman; for others, it offers a darker path toward becoming Frankenstein’s monster. This paper will look at a growing chorus of calls for human enhancement to be embraced and unrestricted. Specifically, we will critically examine recent “pro-enhancement” arguments – articulated in More Than Human by Ramez Naam,[2] as one of the most visible works on the subject today – and conclude that they ultimately need to be strengthened, if they are to be convincing. Our overarching motive here is not so much that we are against human enhancement technologies; that seems to be too premature a conclusion given the state of research and debate, and such technologies may be inevitable anyway. However, we believe that a skeptical eye should be applied to claims that there should be no restrictions on any particular action. Even our most cherished human rights are bounded by reason or societal norms, for whatever they are worth. For instance, our right to free speech still does not allow us to yell “Fire!” in a crowded theater or to slander others. Our right to fall in love and to make love with whom we want does not extend to children. And for all the talk about the virtues of a “free market” or “free trade”, the invisible hand of our economy is still occasionally slapped by anti-trust lawsuits, which would not be an issue if the market were truly free. So even if human enhancement seems to be a reasonable practice and even a right, restrictions may still be required to mitigate undesirable circumstances or unintended consequences – which would be consistent with how functioning societies treat other liberties, values and rights.

Nanoethics is a contentious field for several reasons. Some believe it should not be recognized as a proper area of study, because they believe that nanotechnology itself is not a true category but rather an amalgamation of other sciences, such as chemistry, physics, and engineering. Critics also allege that nanoethics does not raise any new issues but rather revisits familiar ones such as privacy. This paper answers such criticisms and sets the context for the papers that follow in this nanoethics symposium.

With multi-year funding from the U.S. National Science Foundation (NSF), a team of researchers has just released a comprehensive report detailing ethical issues arising from human enhancement (Allhoff et al. 2009). While we direct the interested reader to that (much longer) report, we also thank the editors of this journal for the invitation to provide an executive summary thereof. This summary highlights key results from each section of that report and does so in a self-standing way; in other words, this summary presupposes no familiarity with the report and offers the opportunity to gain quick familiarity with its most central findings.

Human enhancement – our ability to use technology to enhance our bodies and minds, as opposed to its application for therapeutic purposes – is a critical issue facing nanotechnology. It will be involved in some of the near-term applications of nanotechnology, with such research labs as MIT’s Institute for Soldier Technologies working on exoskeletons and other innovations that increase human strength and capabilities. It is also a core issue related to far-term predictions in nanotechnology, such as longevity, nanomedicine, artificial intelligence and other issues

This paper presents the principal findings from a three-year research project funded by the US National Science Foundation on ethics of human enhancement technologies. To help untangle this ongoing debate, we have organized the discussion as a list of questions and answers, starting with background issues and moving to specific concerns, including: freedom & autonomy, health & safety, fairness & equity, societal disruption, and human dignity. Each question-and-answer pair is largely self-contained, allowing the reader to skip to those issues of interest without affecting continuity.
