Cognitive enhancement takes many and diverse forms. Various methods of cognitive enhancement have implications for the near future. At the same time, these technologies raise a range of ethical issues. For example, they interact with notions of authenticity, the good life, and the role of medicine in our lives. Present and anticipated methods for cognitive enhancement also create challenges for public policy and regulation.

Does human enhancement threaten our dignity as some prominent commentators have asserted? Or could our dignity perhaps be technologically enhanced? After disentangling several different concepts of dignity, this essay focuses on the idea of dignity as a quality, a kind of excellence admitting of degrees and applicable to entities both within and without the human realm. I argue that dignity in this sense interacts with enhancement in complex ways which bring to light some fundamental issues in value theory, and that (...) the effects of any given enhancement must be evaluated in its appropriate empirical context. Yet it is possible that through enhancement we could become better able to appreciate and secure many forms of dignity that are overlooked or missing under current conditions. I also suggest that in a posthuman world, dignity as a quality could grow in importance as an organizing moral/aesthetic idea. (shrink)

Positions on the ethics of human enhancement technologies can be (crudely) characterized as ranging from transhumanism to bioconservatism. Transhumanists believe that human enhancement technologies should be made widely available, that individuals should have broad discretion over which of these technologies to apply to themselves, and that parents should normally have the right to choose enhancements for their children-to-be. Bioconservatives (whose ranks include such diverse writers as Leon Kass, Francis Fukuyama, George Annas, Wesley Smith, Jeremy Rifkin, and Bill McKibben) are generally (...) opposed to the use of technology to modify human nature. A central idea in bioconservativism is that human enhancement technologies will undermine our human dignity. To forestall a slide down the slippery slope towards an ultimately debased ‘posthuman’ state, bioconservatives often argue for broad bans on otherwise promising human enhancements. This paper distinguishes two common fears about the posthuman and argues for the importance of a concept of dignity that is inclusive enough to also apply to many possible posthuman beings. Recognizing the possibility of posthuman dignity undercuts an important objection against human enhancement and removes a distortive double standard from our field of moral vision. (shrink)

A provocative work by medical ethicist James Hughes, Citizen Cyborg argues that technologies pushing the boundaries of humanness can radically improve our quality of life if they are controlled democratically. Hughes challenges both the technophobia of Leon Kass and Francis Fukuyama and the unchecked enthusiasm of others for limitless human enhancement. He argues instead for a third way, "democratic transhumanism," by asking the question destined to become a fundamental issue of the twenty-first century: How can we use new cybernetic and (...) biomedical technologies to make life better for everyone? These technologies hold great promise, but they also pose profound challenges to our health, our culture, and our liberal democratic political system. By allowing humans to become more than human - "posthuman" or "transhuman" - the new technologies will require new answers for the enduring issues of liberty and the common good. What limits should we place on the freedom of people to control their own bodies? Who should own genes and other living things? Which technologies should be mandatory, which voluntary, and which forbidden? For answers to these challenges, Citizen Cyborg proposes a radical return to a faith in the resilience of our democratic institutions. (shrink)

A controversial scientific vision predicts a time in which humans and machines will merge and create a new form of non-biological intelligence, explaining how the occurrence will solve such issues as pollution, hunger, and aging.

Francis Fukuyama's controversial new book, Our Posthuman Future: Consequences of the Biotechnology Revolution, has elicited varied reactions, but like it or not, it seems likely to be influential. Here are three opinions. —Ed.

In Enhancing Evolution, leading bioethicist John Harris dismantles objections to genetic engineering, stem-cell research, designer babies, and cloning and makes an ethical case for biotechnology that is both forthright and rigorous. Human enhancement, Harris argues, is a good thing--good morally, good for individuals, good as social policy, and good for a genetic heritage that needs serious improvement. Enhancing Evolution defends biotechnological interventions that could allow us to live longer, healthier, and even happier lives by, for example, providing us with immunity (...) from cancer and HIV/AIDS. Further, Harris champions the possibility of influencing the very course of evolution to give us increased mental and physical powers--from reasoning, concentration, and memory to strength, stamina, and reaction speed. Indeed, he says, it's not only morally defensible to enhance ourselves; in some cases, it's morally obligatory. In a new preface, Harris offers a glimpse at the new science and technology to come, equipping readers with the knowledge to assess the ethics and policy dimensions of future forms of human enhancement.

Bioethics represents a dramatic revision of the centuries-old professional ethics that governed the behavior of physicians and their relationships with patients. This venerable ethics code was challenged in the years after World War II by the remarkable advances in the biomedical sciences and medicine that raised questions about the definition of death, the use of life-support systems, organ transplantation, and reproductive interventions. In response, philosophers and theologians, lawyers and social scientists joined together with physicians and scientists to rethink and revise (...) the old standards. Governments established commissions to recommend policies. Courts heard arguments and legislatures passed laws. This book is the first broad history of the growing field of bioethics. Covering the period 1947-1987, it examines the origin and evolution of the debates over human experimentation, genetic engineering, organ transplantation, termination of life-sustaining treatment, and new reproductive technologies. It assesses the contributions of philosophy, theology, law and the social sciences to the expanding discourse of bioethics. Written by one of the field's founders, The Birth of Bioethics is based on extensive archival research into sources that are difficult to obtain and on interviews with many of the leading figures in the moral debates in medicine. A very readable and comprehensive account of the evolution of bioethics, this book stresses the history of ideas but does not neglect the social and cultural context and the people involved. It will serve the information needs of philosophers, ethicists, social historians, and everyone interested in the origins of some of today's most hotly debated issues. (shrink)

With the rapid progress and considerable promise of nanobiotechnology/neurosciences there is the potential of transforming the very nature of human beings and of how humans can conceive of themselves as rational animals through technological innovations. The interface between humans and machines (neuro-digital interface), can potentially alter what it means to be human, i.e., the very idea of human nature and of normal functioning will be changed. In this paper, I argue that we are potentially on the verge of a paradigm (...) shift in terms of the ends and goals of techno-science and its applications in the biomedical sciences. In particular, the development of brain-computer interfaces could reconceptualize the very notion of what it means to be human. Hence, we should not limit our reflections of applications in terms of therapy and enhancement but also include an examination of applications aiming at the alteration of human nature. To this end I will first delineate the potential paradigm shift and then map out four distinct clusters of concerns in relation to the brain-computer interface. Finally, I argue that our moral and philosophical reflections should follow a procedural model based on managed consensus due to our pluralistic context. (shrink)

This review essay examines H. Tristram Engelhardt, Jr.'s The Foundations of Bioethics, a contemporary nonfeminist text in mainstream biomedical ethics. It focuses upon a central concept, Engelhardt's idea of the moral community and argues that the most serious problem in the book is its failure to take account of the political and social structures of moral communities, structures which deeply affect issues in biomedical ethics.

The book challenges the values of much of contemporary bioethics and health care policy by confronting their failure to secure the moral norms they seek to apply.

In October 2005, the United Nations Educational, Scientific and Cultural Organization adopted the Universal Declaration on Bioethics and Human Rights . A concept of central importance in the declaration is that of “human dignity”. However, there is lack of clarity about its scope, especially concerning the question of whether prenatal human life has the same dignity and rights as born human beings. This ambiguity has implications for the interpretation of important articles of the delcaration, including 2, 4, 8, 10 and (...) 11. The paper applies relevant provisions of the UDBHR to specific cases, addresses problems of internal consistency and considers attempts at clarifying the scope of “human dignity” by the negotiating parties. An analysis of the important relationship between the UDBHR and the Universal Declaration of Human Rights, to which the UDBHR refers in its title and elsewhere, shows that because of a crucial emphatic asymmetry, a broad reading according to which the UDBHR must be understood to ascribe human rights and dignity to prenatal life is untenable. However, the view that the UDBHR confers human rights and dignity on humans from the moment of birth onwards is robust and defensible. This conclusion is important for a proper understanding of the declaration and its use, as stated in Articles 1 and 22, the latter urging states “… to give effect to the principles … in this declaration”. Similarly, it has implications for the use of the declaration in the wider context of bioethics-related law and policy, as well as in academic and other discussions where increasing reference to the UDBHR is likely.
