It is often argued that it does not matter morally whether biomedical interventions treat or prevent diseases or enhance nondisease traits; what matters is whether and how much they promote well-being. Therapy and enhancement both promote well-being, the argument goes, so they are not morally distinct but instead continuous. I provide three reasons why this argument should be rejected when it is applied to choices concerning the genetic makeup of future people. First, it rests on too simple a conception of (...) the badness of disease. Second, it wrongly assumes that disease avoidance and enhancement can proceed with similar accuracy. Third, it overlooks that disease avoidance tends to be more urgent than enhancement from the point of view of distributive justice. Although none of these reasons establishes a firm therapy-enhancement distinction, they show that a continuum model is not an attractive alternative. (shrink)

What's wrong with designer children, bionic athletes, and genetic engineering.

In the second half of the twentieth century, humanism— namely, the worldview that underpinned Western thought for several centuries—has been severely critiqued by philosophers who highlighted its theoretical and ethical limitations. Inspired by the emergence of cybernetics and new technologies such as robotics, prosthetics, communications, artificial intelligence, genetic engineering, and nanotechnology, there has been a desire to articulate a new worldview that will fit the posthuman condition. Posthumanism is a description of a new form of human existence in which the (...) boundaries between humans and nature and humans and machines are blurred, as well as a prescription for an ideal situation in which the limitations of human biology are transcended, replaced by machines. The transition from the human condition to the posthuman condition will be facilitated by transhumanism, the project of human enhancement that will ultimately yield the transformation of the human species from the human to the posthuman. As an intellectual movement, transhumanism is still very small, but transhumanist ideas exert deep and broad influence on contemporary culture and society. This essay highlights the religious dimension of transhumanism and argues that it should be seen as a secularist faith: transhumanism secularizes traditional religious themes, concerns, and goals, while endowing technology with religious significance. Science‐Religion Studies is the most appropriate context to explore the cultural significance of transhumanism. (shrink)

Claims that science should be more democratic than it is frequently arouse opposition. In this essay, I distinguish my own views about the democratization of science from the more ambitious theses defended by Paul Feyerabend. I argue that it is unlikely that the complexity of some scientific debates will allow for resolution according to the methodological principles of any formal confirmation theory, suggesting instead that major revolutions rest on conflicts of values. Yet these conflicts should not be dismissed as irresoluble.

In the course of developing his arguments against making genetic enhancements to one's children, Habermas assumes that a clear line can be drawn between the natural and the manufactured. But given the current state of medical science, this is precisely what we can no longer take for granted.

Winner of the 1975 National Book Award, this brilliant and widely acclaimed book is a powerful philosophical challenge to the most widely held political and social positions of our age--liberal, socialist, and conservative.

We are walking too quickly down the road to physical and psychological utopia without pausing to assess the potential damage to our humanity from this brave new ...

We outline a number of ethical objections to genetic technologies aimed at enhancing human capacities and traits. We then argue that, despite the persuasiveness of some of these objections, they are insufficient to stop the development and use of genetic enhancement technologies. We contend that the inevitability of the technologies results from a particular guiding worldview of humans as masters of the human evolutionary future, and conclude that recognising this worldview points to new directions for ethical thinking about genetic enhancement (...) technologies.

Over the years, I have lectured about various enhancements and modifications of the human body; now I am going to deal more with the whys than the hows. I am hoping to demonstrate why the freedom to modify one's body is essential not just to transhumanism, but also to any future democratic society.

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)

This article critically examines one of the most prevalent metaphors in modern biology, namely the machine conception of the organism (MCO). Although the fundamental differences between organisms and machines make the MCO an inadequate metaphor for conceptualizing living systems, many biologists and philosophers continue to draw upon the MCO or tacitly accept it as the standard model of the organism. This paper analyses the specific difficulties that arise when the MCO is invoked in the study of development and evolution. In (...) developmental biology the MCO underlies a logically incoherent model of ontogeny, the genetic program, which serves to legitimate three problematic theses about development: genetic animism, neo-preformationism, and developmental computability. In evolutionary biology the MCO is responsible for grounding unwarranted theoretical appeals to the concept of design as well as to the interpretation of natural selection as an engineer, which promote a distorted understanding of the process and products of evolutionary change. Overall, it is argued that, despite its heuristic value, the MCO today is impeding rather than enabling further progress in our comprehension of living systems. (shrink)

In a near-future world of bionics and biotechnology, the main ethical and political issue will be the definition of who we are. Could biomedical enhancements transform us to such an extent that we would be other than human? Habermas argues that any genetic enhancement intervention that could potentially alter ‘human nature’ should be morally prohibited since it alters the child’s nature or the very essence that makes the child who he is. This practice also commits the child to a specific (...) life project or, in any case, it puts specific restrictions on his freedom to choose a life of his own. Ultimately, genetic enhancement jeopardizes the very foundations of moral equality. I contend that Habermas’ argument is based either on a series of presuppositions that imply a gross misunderstanding of evolution or the relevant factual information cocerning the action we are about to morally assess is not empirically supported. Hence, the argument from human nature is based on a series of false or problematic assumptions, and, as such, it fails to play the normative role intended by Habermas. (shrink)

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.

Unfit for the Future argues that the future of our species depends on radical enhancement of the moral aspects of our nature. Population growth and technological advances are threatening to undermine the conditions of worthwhile life on earth forever. We need to modify the biological bases of human motivation to deal with this challenge.

Stuart Kauffman here presents a brilliant new paradigm for evolutionary biology, one that extends the basic concepts of Darwinian evolution to accommodate recent findings and perspectives from the fields of biology, physics, chemistry and mathematics. The book drives to the heart of the exciting debate on the origins of life and maintenance of order in complex biological systems. It focuses on the concept of self-organization: the spontaneous emergence of order widely observed throughout nature. Kauffman here argues that self-organization plays an (...) important role in the emergence of life itself and may play as fundamental a role in shaping life's subsequent evolution as does the Darwinian process of natural selection. Yet until now no systematic effort has been made to incorporate the concept of self-organization into evolutionary theory. The construction requirements which permit complex systems to adapt remain poorly understood, as is the extent to which selection itself can yield systems able to adapt more successfully. This book explores these themes. It shows how complex systems, contrary to expectations, can spontaneously exhibit stunning degrees of order, and how this order, in turn, is essential for understanding the emergence and development of life on Earth. Topics include the new biotechnology of applied molecular evolution, with its important implications for developing new drugs and vaccines; the balance between order and chaos observed in many naturally occurring systems; new insights concerning the predictive power of statistical mechanics in biology; and other major issues. Indeed, the approaches investigated here may prove to be the new center around which biologicalscience itself will evolve. The work is written for all those interested in the cutting edge of research in the life sciences. (shrink)

Opponents of biomedical enhancement frequently adopt what Allen Buchanan has called the “Personal Goods Assumption.” On this assumption, the benefits of biomedical enhancement will accrue primarily to those individuals who undergo enhancements, not to wider society. Buchanan has argued that biomedical enhancements might in fact have substantial social benefits by increasing productivity. We outline another way in which enhancements might benefit wider society: by augmenting civic virtue and thus improving the functioning of our political communities. We thus directly confront critics (...) of biomedical enhancement who argue that it will lead to a loss of social cohesion and a breakdown in political life. (shrink)

Biomedical enhancements, the applications of medical technology to make better those who are neither ill nor deficient, have made great strides in the past few decades. Using Amartya Sen's capability approach as my framework, I argue in this article that far from being simply permissible, we have a prima facie moral obligation to use these new developments for the end goal of promoting social justice. In terms of both range and magnitude, the use of biomedical enhancements will mark a radical (...) advance in how we compensate the most disadvantaged members of society. (shrink)

There has been considerable recent debate on the ethics of human enhancement. A number of prominent authors have been concerned about or critical of the use of technology to alter or enhance human beings, citing threats to human nature and dignity as one basis for these concerns. Frances Kamm has given a detailed rebuttal of Sandel's arguments, arguing that human enhancement is permissible. Nicholas Agar, in his book Liberal Eugenics, argues that enhancement should be permissible but not obligatory. He argues (...) that what distinguishes liberal eugenics from the objectionable eugenic practices of the Nazis is that it is not based on a single conception of a desirable genome and that it is voluntary and not obligatory. This article takes a more provocative position. It aims to argue that, far from its being merely permissible, we have a moral obligation or moral reason to enhance ourselves and our children. Indeed, we have the same kind of obligation as we have to treat and prevent disease. It begins by considering the current interests in and possibilities of enhancement. It then offers three arguments that we have very strong reasons to seek to enhance. (shrink)

Since it is now broadly acknowledged that ethics should receive early consideration in discourse on emerging technologies, ethical debates tend to flourish even while new fields of technology are still in their infancy. Such debates often liberally mix existing applications with technologies in the pipeline and far-reaching visions. This paper analyses the problems associated with this use of ethics as “preparatory” research, taking discourse on human enhancement in general and on pharmaceutical cognitive enhancement in particular as an example. The paper (...) will outline and discuss the gap between the scientific and technological state of the art and the ethical debates, pointing out epistemic problems in this context. Furthermore, it will discuss the future role of genuine ethical reflection in discourse on human enhancement, arguing also that such discourse needs to include a technology assessment—in the broad sense of the term—which encompasses, inter alia, anthropological perspectives and aspects of social theory.

Julian Savulescu argues for two principles of reproductive ethics: reproductive autonomy and procreative beneficence, where the principle of procreative beneficence is conceptualised in terms of a duty to have the child, of the possible children that could be had, who will have the best opportunity of the best life. Were it to be accepted, this principle would have significant implications for the ethics of reproductive choice and, in particular, for the use of prenatal testing and other reproductive technologies for the (...) avoidance of disability, and for enhancement. In this paper, it is argued that this principle should be rejected, and it is concluded that while potential parents do have important obligations in relation to the foreseeable lives of their future children, these obligations are not best captured in terms of a duty to have the child with the best opportunity of the best life.

This paper argues that both technological determinism (the development of technology is uniquely determined by internal laws) and technological voluntarism (technological change can be externally directed and regulated by the wants and free choice of human beings) are one‐sided and partly mistaken. The determinists are right in the sense that technology has a power to influence our values and behaviour, and thereby appear to direct ‘technological imperatives’ to us. However, such commands are always conditional on some value premises; the voluntarists (...) are thus right in pointing out that we need not obey such imperatives. The principle ‘Can implies Ought’ (all technological possibilities should be realized) is therefore invalid. (shrink)

Much of the debate about the ethics of enhancement has proceeded according to two framing assumptions. The first is that although enhancement carries large social risks, the chief benefits of enhancement are to those who are enhanced (or their parents, in the case of enhancing the traits of children). The second is that, because we now understand the wrongs of state-driven eugenics, enhancements, at least in liberal societies, will be personal goods, chosen or not chosen in a market for enhancement (...) services. This article argues that both framing assumptions must be rejected, once it is understood that some enhancements— especially those that are most likely to garner resources and become widespread— will increase human productivity. Once one appreciates the productivity-increasing potential of enhancements, one can begin to see that enhancement need not be primarily a zero sum affair, that the social costs of forgoing enhancements may be great, and that the state may well take an interest in facilitating biomedical enhancements, just as it does in facilitating education and other productivity-increasing traditional enhancements. Appreciating the productivity-increasing potential of enhancements also makes it possible to view the enhancement debate in a new light, through the lens of the ethics of development. (shrink)

Extreme human enhancement could result in “posthuman” modes of being. After offering some definitions and conceptual clarification, I argue for two theses. First, some posthuman modes of being would be very worthwhile. Second, it could be very good for human beings to become posthuman.

I argue that the title question needs to be taken seriously because there are important questions about how the scientific agenda should be set. Natural answers to the question – declarations of the proper autonomy of science or expressions of faith in market forces – are found inadequate. Instead, I propose a form of democracy with respect to scientific research that will avoid the obvious dangers of a tyranny of ignorance. I conclude with some modest proposals about how the ideal (...) of a democratic science might be implemented and with a response to common objections. (shrink)

An essential introduction to the philosophy of biology This is a concise, comprehensive, and accessible introduction to the philosophy of biology written by a leading authority on the subject. Geared to philosophers, biologists, and students of both, the book provides sophisticated and innovative coverage of the central topics and many of the latest developments in the field. Emphasizing connections between biological theories and other areas of philosophy, and carefully explaining both philosophical and biological terms, Peter Godfrey-Smith discusses the relation between (...) philosophy and science; examines the role of laws, mechanistic explanation, and idealized models in biological theories; describes evolution by natural selection; and assesses attempts to extend Darwin's mechanism to explain changes in ideas, culture, and other phenomena. Further topics include functions and teleology, individuality and organisms, species, the tree of life, and human nature. The book closes with detailed, cutting-edge treatments of the evolution of cooperation, of information in biology, and of the role of communication in living systems at all scales. Authoritative and up-to-date, this is an essential guide for anyone interested in the important philosophical issues raised by the biological sciences. (shrink)

Some writers claim that ethicists involved in assessing future technologies like nanotechnology and human enhancement devote too much time to debating issues that may or may not arise, at the expense of addressing more urgent, current issues. This practice has been claimed to squander the scarce and valuable resource of ethical concern. I assess this view, and consider some alternatives to ‘speculative ethics’ that have been put forward. I argue that attempting to restrict ethical debate so as to avoid considering (...) unacceptably speculative scenarios would not only leave scientific progress devoid of ethical guidance, but would also rule out some of our most important ethical projects. I conclude that the issue of speculation is a red herring: what is most important is not that ethicists concentrate on current issues or those that are most likely to arise; but that ethicists, scientists, and others focus on maximising what is most valuable.

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. (shrink)

:Many critics of bioenhancement go to considerable lengths to establish the existence of reasons against pursuing bioenhancements but do little to establish the absence of reasons in favor. This suggests that they accept what Allen Buchanan has called the conclusive reasons view. According to this view, our reasons against bioenhancement are obviously decisive, so there is no need to balance them against countervailing reasons. Buchanan criticizes the CRV by showing that the reasons most commonly adduced against bioenhancement are not decisive, (...) or, at least, not obviously so.In this article, I suggest that both Buchanan and the authors to whom he is responding underestimate the strength of the case for the CRV. There are, I argue, harm-based reasons against bioenhancement that provide stronger support to the CRV than the reasons that have most often been adduced by critics of enhancement. However, I then argue that even these harm-based reasons are not obviously decisive. Thus, I ultimately agree with Buchanan about the falsity of the CRV, though I disagree with him about the reasons for its falsity. (shrink)

The term “posthuman” has been used in very different senses by different authors.2 I am sympathetic to the view that the word often causes more confusion than clarity, and that we might be better off replacing it with some alternative vocabulary.

Developments in medical science have afforded us the opportunity to improve and enhance the human species in ways unthinkable to previous generations. Whether it's making changes to mitochondrial DNA in a human egg, being prescribed Prozac, or having a facelift, our desire to live longer, feel better and look good has presented philosophers, medical practitioners and policy-makers with considerable ethical challenges. But what exactly constitutes human improvement? What do we mean when we talk of making "better" humans? In this book (...) Michael Hauskeller explores these questions and the ideas of human good that underpin them. Posing some challenging questions about the nature of human enhancement, he interrogates the logic behind its processes and examines the justifications behind its criteria. Questioning common assumptions about what constitutes human improvement, Hauskeller asks whether the criteria proposed by its advocates are convincing. The book draws on recent research as well as popular representations of human enhancement from advertising to the internet, and provides a non-technical and accessible survey of the issues for readers and students interested in the ethics and politics of human enhancement.
