A person can be true to oneself even while transforming and even creating the person one is. One's self is not something merely waiting to be discovered, after all. To some extent, part of the human endeavor is deciding and trying to become who we want to be.

Appeals to the idea of human nature are frequent in the voluminous literature on the ethics of enhancing human beings through biotechnology. Two chief concerns about the impact of enhancements on human nature have been voiced. The first is that enhancement may alter or destroy human nature. The second is that if enhancement alters or destroys human nature, this will undercut our ability to ascertain the good because, for us, the good is determined by our nature. The first concern assumes (...) that altering or destroying human nature is in itself a bad thing. The second concern assumes that human nature provides a standard without which we cannot make coherent, defensible judgments about what is good. I will argue (1) that there is nothing wrong, per se, with altering or destroying human nature, because, on a plausible understanding of what human nature is, it contains bad as well as good characteristics and there is no reason to believe that eliminating some of the bad would so imperil the good as to make the elimination of the bad impermissible, and (2) that altering or destroying human nature need not result in the loss of our ability to make judgments about the good, because we possess a conception of the good by which we can and do evaluate human nature. I will argue that appeals to human nature tend to obscure rather than illuminate the debate over the ethics of enhancement and can be eliminated in favor of more cogent considerations. (shrink)

This chapter concentrates mainly on biomedical cognitive enhancements, but many of the remarks apply equally to enhancements that work on non‐cognitive capacities, and to non‐biomedical means of enhancement. Proponents of a positive right to enhancements could argue their case on grounds of fairness or equality, or on grounds of a public interest in the promotion of the capacities required for autonomous agency. The societal benefits of effective cognitive enhancement may turn out to be so large and unequivocal that it would (...) be economically efficient to subsidize enhancement for the poor, just as the state now subsidizes education. The example on iodine deficiency illustrates that cognitive enhancement policy need not center on preparing the ground for sophisticated, yet‐to‐be‐realized technologies. “Smart policy” should, rather, take as its starting point the recognition that effective cognition is not only subjectively valuable to individuals, but also delivers significant social, cultural, financial, and scientific benefits.

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.

It is my view that one essential difference between persons and other creatures is to be found in the structure of a person's will. Besides wanting and choosing and being moved to do this or that, men may also want to have certain desires and motives. They are capable of wanting to be different, in their preferences and purposes, from what they are. Many animals appear to have the capacity for what I shall call "first-order desires" or "desires of the (...) first order," which are simply desires to do or not to do one thing or another. No animal other than man, however, appears to have the capacity for reflective self-evaluation that is manifested in the formation of second-order desires. (shrink)

This chapter explores the questions “What policy tools do we have to deal with human biological enhancements?” as well as “What policy tools do we need?.” After discussing the policy tools available in the United States, it examines their adequacy in coping with human biological enhancements in two respects – how easy they would be to adopt and how easy they would be to enforce. In each category, three major issues raised by human biological enhancement are considered: safety, coercion, and (...) fairness. It looks first at the adoption of, then at the enforcement of, policy tools available in the United States to cope with three real problems raised by such enhancements. It concludes that some policy tools needed to deal with enhancement already exist but need to be better focused. New legislation is the most direct way for the federal government to implement policy, but it is rarely easy. (shrink)

Advances in biotechnology have enabled interventions in the human organism that promise to increase physical and intellectual perform over the 'normal' or 'natural' boundary, as well as make possible targeted changes in human experience. The author investigates ethical debates surrounding these issues with a particular focus on arguments that employ a normative concept of a person in order to establish that particular interventions are permissible or impermissible. He develops an integrated model that 'maps' of the concept of a human being, (...) thereby bringing the normative elements of the concept to the fore. Nevertheless, with a view to issues of risk and justice, the author argues that anthropological arguments are only one elements of a comprehensive ethics of enhancement. (shrink)

We respond to a number of objections raised by John Harris in this journal to our argument that we should pursue genetic and other biological means of morally enhancing human beings (moral bioenhancement). We claim that human beings now have at their disposal means of wiping out life on Earth and that traditional methods of moral education are probably insufficient to achieve the moral enhancement required to ensure that this will not happen. Hence, we argue, moral bioenhancement should be sought (...) and applied. We argue that cognitive enhancement and technological progress raise acute problems because it is easier to harm than to benefit. We address objections to this argument. We also respond to objections that moral bioenhancement: (1) interferes with freedom; (2) cannot be made to target immoral dispositions precisely; (3) is redundant, since cognitive enhancement by itself suffices.

Beginning with the assumptions that genetic technology will make possible the enhancement of some significant human capacities and that our society will have self-evident reasons to pursue such enhancements, this essay suggests less evident reasons to proceed with extreme caution. The essay asks: Will we, in our attempts to enhance humans by reducing their subjection to chance and change, inadvertently impoverish them? It explores how technologies aimed at enhancement might affect the good that is our experience of some forms of (...) the beautiful and the excellent, the good that is relationships of care, and the good that is diversity across the life span. In the end, it speculates about the fundamental philosophical difference that underlies the disagreement between those who would tend to embrace a project to enhance human capacities and those who would tend to criticize such a project.

Prominent thinkers such as Jurgen Habermas and Michael Sandel are warning that biomedical enhancements will undermine fundamental political values. Yet whether biomedical enhancements will undermine such values depends on how biomedical enhancements will function, how they will be administered and to whom. Since only few enhancements are obtainable, it is difficult to tell whether these predictions are sound. Nevertheless, such warnings are extremely valuable. As a society we must, at the very least, be aware of developments that could have harmful (...) consequences. Indeed, if important values were to be jeopardized, we should take appropriate measures to protect them. This paper focuses on four central values: solidarity, personal responsibility, equality and autonomy. It delineates the conditions under which biomedical enhancements would undermine these values. It also details the circumstances under which these values would be unaffected by enhancements as well as those under which they would be promoted. Specifying these conditions is valuable; it would enable society to prepare appropriate ethical guidelines and policy responses in advance. (shrink)

Some philosophers have criticized the use of psychopharmaceuticals on the grounds that even if these drugs enhance the person using them, they threaten their authenticity. Others have replied by pointing out that the conception of authenticity upon which this argument rests is contestable; on a rival conception, psychopharmaceuticals might be used to enhance our authenticity. Since, however, it is difficult to decide between these competing conceptions of authenticity, the debate seems to end in a stalemate. I suggest that we need (...) not resolve this debate to end the stalemate. New technologies which alter the self can be understood within the framework of the first conception of authenticity, I suggest, not as threatening the authentic self, but rather as bringing the outward appearance of the self into line with its deepest essence. Since psychopharmaceutical use can plausibly be understood on this model, it can be seen as enhancing our authenticity on either conception. (shrink)

This comprehensive reference provides an exhaustive guide to current scholarship on the perennial problem of Free Will--perhaps the most hotly and voluminously debated of all philosophical problems. While reference is made throughout to the contributions of major thinkers of the past, the emphasis is on recent research. The essays, most of which are previously unpublished, combine the work of established scholars with younger thinkers who are beginning to make significant contributions. Taken as a whole, the Handbook provides an engaging and (...) accessible roadmap to the state of the art thinking on this enduring topic. (shrink)

This paper identifies human enhancement as one of the most significant areas of bioethical interest in the last twenty years. It discusses in more detail one area, namely moral enhancement, which is generating significant contemporary interest. The author argues that so far from being susceptible to new forms of high tech manipulation, either genetic, chemical, surgical or neurological, the only reliable methods of moral enhancement, either now or for the foreseeable future, are either those that have been in human and (...) animal use for millennia, namely socialization, education and parental supervision or those high tech methods that are general in their application. By that is meant those forms of cognitive enhancement that operate across a wide range of cognitive abilities and do not target specifically ‘ethical’ capacities. The paper analyses the work of some of the leading contemporary advocates of moral enhancement and finds that in so far as they identify moral qualities or moral emotions for enhancement they have little prospect of success.

Recent developments in biotechnology and genetic research are raising complex ethical questions concerning the legitimate scope and limits of genetic intervention. As we begin to contemplate the possibility of intervening in the human genome to prevent diseases, we cannot help but feel that the human species might soon be able to take its biological evolution in its own hands. 'Playing God' is the metaphor commonly used for this self-transformation of the species, which, it seems, might soon be within our grasp. (...) In this important new book, Jurgen Habermas - the most influential philosopher and social thinker in Germany today - takes up the question of genetic engineering and its ethical implications and subjects it to careful philosophical scrutiny. His analysis is guided by the view that genetic manipulation is bound up with the identity and self-understanding of the species. We cannot rule out the possibility that knowledge of one's own hereditary factors may prove to be restrictive for the choice of an individual's way of life and may undermine the symmetrical relations between free and equal human beings. In the concluding chapter - which was delivered as a lecture on receiving the Peace Prize of the German Book Trade for 2001 - Habermas broadens the discussion to examine the tension between science and religion in the modern world, a tension which exploded, with such tragic violence, on September 11th.

Cognitive enhancement may be defined as the amplification or extension of core capacities of the mind through improvement or augmentation of internal or external information processing systems. Cognition refers to the processes an organism uses to organize information. These include acquiring information (perception), selecting (attention), representing (understanding) and retaining (memory) information, and using it to guide behavior (reasoning and coordination of motor outputs). Interventions to improve cognitive function may be directed at any of these core faculties.

This book, written by four internationally renowned bioethicists and first published in 2000, was the first systematic treatment of the fundamental ethical issues underlying the application of genetic technologies to human beings. Probing the implications of the remarkable advances in genetics, the authors ask how should these affect our understanding of distributive justice, equality of opportunity, the rights and obligations as parents, the meaning of disability, and the role of the concept of human nature in ethical theory and practice. The (...) book offers a historical context to contemporary debate over the use of these technologies by examining the eugenics movement of the late nineteenth and early twentieth centuries. The questions raised in this book will be of interest to any reflective reader concerned about science and society and the rapid development of biotechnology, as well as to professionals in such areas as philosophy, bioethics, medical ethics, health management, law, and political science.
